+# Client IP address middleware
+
+PSR-7 Middleware that determines the client IP address and stores it as an `ServerRequest` attribute called `ip_address`.
+
+[![Build status][Master image]][Master]
+
+
+This middleware checks the 'X-Forwarded-For', 'X-Forwarded', 'X-Cluster-Client-Ip', 'Client-Ip' headers for the first IP address it can find. If none of the headers exist, or do not have a valid IP address, then the `$_SERVER['REMOTE_ADDR']` is used.
+
+*Note that the proxy headers are only checked if the first parameter to the constructor is set to `true`. If set to false, then only `$_SERVER['REMOTE_ADDR']` is used*
+
+**Trusted Proxies**
+
+You can set a list of proxies that are trusted as the second constructor parameter. If this list is set, then the proxy headers will only be checked if the `REMOTE_ADDR` is in the trusted list.
+
+
+## Installation
+
+`composer require akrabat/rka-ip-address-middleware`
+
+## Usage
+
+In Slim 3:
+
+```php
+$checkProxyHeaders = true; // Note: Never trust the IP address for security processes!
+$trustedProxies = ['10.0.0.1', '10.0.0.2']; // Note: Never trust the IP address for security processes!
+$app->add(new RKA\Middleware\IpAddress($checkProxyHeaders, $trustedProxies));
+
+$app->get('/', function ($request, $response, $args) {
+    $ipAddress = $request->getAttribute('ip_address');
+
+    return $response;
+});
+```
+
+## Testing
+
+* Code coverage: ``$ vendor/bin/phpcs``
+* Unit tests: ``$ vendor/bin/phpunit``
+* Code coverage: ``$ vendor/bin/phpunit --coverage-html ./build``

+# Contribute to PHP-Cache*
+
+Thank you for contributing to PHP-Cache!
+
+Before we can merge your Pull-Request here are some guidelines that you need to follow.
+These guidelines exist not to annoy you, but to keep the code base clean,
+unified and future proof.
+
+## We only accept PRs  to "master"
+
+Our branching strategy is "everything to master first", even
+bugfixes and we then merge them into the stable branches. You should only 
+open pull requests against the master branch. Otherwise we cannot accept the PR.
+
+There is one exception to the rule, when we merged a bug into some stable branches
+we do occasionally accept pull requests that merge the same bug fix into earlier
+branches.
+
+## Coding Standard
+
+We use PSR-1 and PSR-2:
+
+* https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-1-basic-coding-standard.md
+* https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md
+
+with some exceptions/differences:
+
+* Keep the nesting of control structures per method as small as possible
+* Align equals (=) signs
+* Prefer early exit over nesting conditions
+
+All pull requests will end up getting run through Style CI, which is required to pass.
+
+## Unit-Tests
+
+Please try to add a test for your pull-request.
+
+* If your test is specific for an adapter/library, put it in the library tests.
+* If it is adapter agnostic, put it in the src/IntegrationTests directory
+
+You can run the unit-tests by calling `composer test` from the root of the project.
+It will run all the tests for each library.
+
+In order to do that, you will need a fresh copy of php-cache/cache, and you
+will have to run a composer installation in the project:
+
+```sh
+git clone git@github.com:php-cache/cache.git
+cd cache
+curl -sS https://getcomposer.org/installer | php --
+./composer.phar install
+```
+
+## Travis
+
+We automatically run your pull request through [Travis CI](http://www.travis-ci.org)
+against on all of the adapters. If you break the tests, we cannot merge your code,
+so please make sure that your code is working before opening up a Pull-Request.
+
+## Getting merged
+
+Please allow us time to review your pull requests. We will give our best to review
+everything as fast as possible, but cannot always live up to our own expectations.
+
+Thank you very much again for your contribution!
+
+\* Any similarities to the Doctrine contributing file is NOT coincidence. We've used their CONTRIBUTING.md file as a basis for ours :)

+
+This directory contains the scripts that travis uses to build the project.
+
+The scripts in [the php directory](php/) are ran when travis is testing the given version and adapter. [`all.sh`](php/all.sh) is ran for all adapters but for one php version.

+Tests are ran using [`runTest.sh`](runTest.sh). This file changes the directory to the library subdirectory, installs composer, and runs the tests.

+This is a PSR-6 cache implementation using a chain of other PSR-6 cache pools. It is a part of the PHP Cache organisation. To read about 
+features like tagging and hierarchy support please read the shared documentation at [www.php-cache.com](http://www.php-cache.com). 
+
+### Install
+
+```bash
+composer require cache/chain-adapter
+```
+
+### Use
+
+You do not need to do any configuration to use the `CachePoolChain`.
+
+```php
+$redisPool = new RedisCachePool($redisClient);
+$apcPool = new ApcCachePool();
+$pool = new CachePoolChain([$apcPool, $redisPool]);
+```
+

+# Change Log
+
+The change log describes what is "Added", "Removed", "Changed" or "Fixed" between each release. 
+
+## 1.0.0
+
+No changes since 0.4.0.
+
+## 0.4.0
+
+### Added
+
+* `AbstractCachePool` has 4 new abstract methods: `getList`, `removeList`, `appendListItem` and `removeListItem`.
+* `AbstractCachePool::invalidateTags` and `AbstractCachePool::invalidateTags` 
+* Added interfaces for our items and pools `PhpCachePool` and `PhpCacheItem`
+* Trait to help adapters to support tags. `TagSupportWithArray`.
+
+### Changed
+
+* First parameter to `AbstractCachePool::storeItemInCache` must be a `PhpCacheItem`. 
+* Return value from `AbstractCachePool::fetchObjectFromCache` must be a an array with 4 values. Added expiration timestamp. 
+* `HasExpirationDateInterface` is replaced by `HasExpirationTimestampInterface`
+* We do not work with `\DateTime` internally anymore. We work with timestamps. 
+
+## 0.3.3
+
+### Fixed
+
+* Bugfix when you fetch data from the cache storage that was saved as "non-tagging item" but fetch as a tagging item.
+
+## 0.3.2
+
+### Added
+
+* Cache pools do implement `LoggerAwareInterface`
+
+## 0.3.0
+
+### Changed
+
+* The `AbstractCachePool` does not longer implement `TaggablePoolInterface`. However, the `CacheItem` does still implement `TaggableItemInterface`.
+* `CacheItem::getKeyFromTaggedKey` has been removed
+* The `CacheItem`'s second parameter is a callable that must return an array with 3 elements; [`hasValue`, `value`, `tags`].
+ 
+## 0.2.0
+ 
+No changelog before this version

+This is a PSR-6 cache implementation using Doctrine cache. It is a part of the PHP Cache organisation. To read about 
+features like tagging and hierarchy support please read the shared documentation at [www.php-cache.com](http://www.php-cache.com). 
+
+This is a PSR-6 to Doctrine bridge. If you are interested in a Doctrine to PSR-6 bridge you should have a look at 
+[PSR-6 Doctrine Bridge](https://github.com/php-cache/doctrine-bridge).
+
+### Install
+
+```bash
+composer require cache/doctrine-adapter
+```
+
+## Use
+
+```php
+use Doctrine\Common\Cache\MemcachedCache;
+use Cache\Adapter\Doctrine\DoctrineCachePool;
+
+
+$memcached = new \Memcached();
+$memcached->addServer('localhost', 11211);
+
+// Create a instance of Doctrine's MemcachedCache
+$doctrineCache = new MemcachedCache();
+$doctrineCache->setMemcached($memcached);
+
+// Wrap Doctrine's cache with the PSR-6 adapter
+$pool = new DoctrineCachePool($doctrineCache);
+```

+
+This is a PSR-6 cache implementation using Filesystem. It is a part of the PHP Cache organisation. To read about 
+features like tagging and hierarchy support please read the shared documentation at [www.php-cache.com](http://www.php-cache.com). 
+
+This implementation is using the excellent [Flysystem](http://flysystem.thephpleague.com/).
+
+### Install
+
+```bash
+composer require cache/filesystem-adapter
+```
+
+### Use
+
+To create an instance of `FilesystemCachePool` you need to configure a `Filesystem` and its adapter. 
+
+```php
+use League\Flysystem\Adapter\Local;
+use League\Flysystem\Filesystem;
+use Cache\Adapter\Filesystem\FilesystemCachePool;
+
+$filesystemAdapter = new Local(__DIR__.'/');
+$filesystem        = new Filesystem($filesystemAdapter);
+
+$pool = new FilesystemCachePool($filesystem);
+```
+
+You can change the folder the cache pool will write to through the `setFolder` setter:
+
+```php
+$pool = new FilesystemCachePool($filesystem);
+$pool->setFolder('path/to/cache');
+```
+
+### Contribute
+
+Contributions are very welcome! Send a pull request to the [main repository](https://github.com/php-cache/cache) or 
+report any issues you find on the [issue tracker](http://issues.php-cache.com).

+This is a PSR-6 cache implementation using Memcached. It is a part of the PHP Cache organisation. To read about 
+features like tagging and hierarchy support please read the shared documentation at [www.php-cache.com](http://www.php-cache.com). 
+
+### Install
+
+```bash
+composer require cache/memcached-adapter
+```
+
+### Use
+
+To create an instance of `MemcachedCachePool` you need to configure a `\Memcached` client. 
+
+```php
+$client = new \Memcached();
+$client->addServer('localhost', 11211);
+$pool = new MemcachedCachePool($client);
+```

+This is a PSR-6 cache implementation using Predis. It is a part of the PHP Cache organisation. To read about 
+features like tagging and hierarchy support please read the shared documentation at [www.php-cache.com](http://www.php-cache.com). 
+
+This implementation is using [Predis](https://github.com/nrk/predis). If you want an adapter with 
+[PhpRedis](https://github.com/phpredis/phpredis) you should look at our [Redis adapter](https://github.com/php-cache/redis-adapter). 
+
+### Install
+
+```bash
+composer require cache/predis-adapter
+```
+
+### Use
+
+To create an instance of `PredisCachePool` you need to configure a `\Predis\Client` object. 
+
+```php
+$client = new \Predis\Client('tcp:/127.0.0.1:6379');
+$pool = new PredisCachePool($client);

+
+This is a PSR-6 cache implementation using Redis. It is a part of the PHP Cache organisation. To read about 
+features like tagging and hierarchy support please read the shared documentation at [www.php-cache.com](http://www.php-cache.com). 
+
+This implementation is using [PhpRedis](https://github.com/phpredis/phpredis). If you want an adapter with 
+[Predis](https://github.com/nrk/predis) you should look at our [Predis adapter](https://github.com/php-cache/predis-adapter). 
+
+### Install
+
+```bash
+composer require cache/redis-adapter
+```
+
+### Use
+
+To create an instance of `RedisCachePool` you need to configure a `\Redis` client. 
+
+```php
+$client = new \Redis();
+$client->connect('127.0.0.1', 6379);
+$pool = new RedisCachePool($client);
+```
+
+
+### Contribute
+
+Contributions are very welcome! Send a pull request to the [main repository](https://github.com/php-cache/cache) or 
+report any issues you find on the [issue tracker](http://issues.php-cache.com).

+
+This library provides a PSR-6 compliant bridge between Doctrine and a Cache Pool. The bridge implements the
+`Doctrine\Common\Cache\Cache` interface. This is useful for projects that require an implementation of
+`Doctrine\Common\Cache\Cache`, but you still want to use a PSR-6 implementation.
+
+### Install
+
+```bash
+composer require cache/psr-6-doctrine-bridge
+```
+
+### Usage
+
+```php
+use Cache\Bridge\Doctrine\DoctrineCacheBridge;
+
+// Assuming $pool is an instance of \Psr\Cache\CacheItemPoolInterface
+$cacheProvider = new DoctrineCacheBridge($pool);
+
+$cacheProvider->contains($key);
+$cacheProvider->fetch($key);
+$cacheProvider->save($key, $value, $ttl);
+$cacheProvider->delete($key);
+
+// Also, if you need it:
+$cacheProvider->getPool(); // same as $pool
+```
+
+### Contribute
+
+Contributions are very welcome! Send a pull request to the [main repository](https://github.com/php-cache/cache) or

+This is a bridge that converts a PSR-6 cache implementation to PSR-16 (SimpleCache). It is a part of the PHP Cache organisation. To read about 
+features like tagging and hierarchy support please read the shared documentation at [www.php-cache.com](http://www.php-cache.com). 
+
+### Install
+
+```bash
+composer require cache/simple-cache-bridge
+```
+
+### Use
+
+You need an existing PSR-6 pool as a cnstructor argument to the bridge. 
+
+```php
+$psr6pool = new ArrayCachePool();
+$simpleCache = new SimpleCacheBridge($psr6pool);
+```

+
+This repository has a encryption wrapper that makes the PSR-6 cache implementation encrypted.
+
+Encryption and decryption are both expensive operations, and frequent reads from an encrypted data store can quickly become a bottleneck in otherwise performant applications. Use encrypted caches sparingly.
+
+
+### Install
+
+```bash
+composer require cache/encryption-cache
+```
+
+### Use
+
+Read the [documentation on usage](http://www.php-cache.com/en/latest/encryption/).
+
+### Implement
+
+Read the [documentation on implementation](http://www.php-cache.com/en/latest/implementing-cache-pools/encryption/).
+
+### Contribute
+
+Contributions are very welcome! Send a pull request to the [main repository](https://github.com/php-cache/cache) or
+report any issues you find on the [issue tracker](http://issues.php-cache.com).

+
+This is a PHP session handler that supports PSR-6 cache. It is a part of the PHP Cache organisation. Find more 
+documentation at [www.php-cache.com](http://www.php-cache.com). 
+
+
+### Install
+
+```bash
+composer require cache/session-handler
+```
+
+### Use
+
+```php
+$pool = new ArrayCachePool();
+$config = ['ttl'=>3600, 'prefix'=>'foobar'];
+
+$sessionHandler = new Psr6SessionHandler($pool, $config);
+```
+
+Note that this session handler does no kind of locking, so it will lose or overwrite your session data if you run scripts concurrently. You have been warned.

+# Changelog
+
+The change log describes what is "Added", "Removed", "Changed" or "Fixed" between each release.
+
+## UNRELEASED
+
+## 1.0.0
+
+### Added
+
+* `Cache\Taggable\Exception\InvalidArgumentException`
+
+### Changed
+
+* We do not throw `Cache\Adapter\Common\Exception\InvalidArgumentException` anymore. Instead we throw 
+`Cache\Taggable\Exception\InvalidArgumentException`. Both exceptions do implement `Psr\Cache\InvalidArgumentException`
+* We do not require `cache/adapter-common`
+
+### Removed
+
+* Deprecated interfaces `TaggableItemInterface` and `TaggablePoolInterface`
+
+## 0.5.1
+
+### Fixed
+
+* Bug on `TaggablePSR6ItemAdapter::isItemCreatedHere` where item value was `null`.
+
+## 0.5.0
+
+### Added
+
+* Support for `TaggableCacheItemPoolInterface`
+
+### Changed
+
+* The behavior of `TaggablePSR6ItemAdapter::getTags()` has changed. It will not return the tags stored in the cache storage. 
+
+### Removed
+
+* `TaggablePoolTrait`
+* Deprecated `TaggablePoolInterface` in favor of `Cache\TagInterop\TaggableCacheItemPoolInterface`
+* Deprecated `TaggableItemInterface` in favor of `Cache\TagInterop\TaggableCacheItemInterface`
+* Removed support for `TaggablePoolInterface` and `TaggableItemInterface`
+* `TaggablePSR6ItemAdapter::getTags()`. Use `TaggablePSR6ItemAdapter::getPreviousTags()`
+* `TaggablePSR6ItemAdapter::addTag()`. Use `TaggablePSR6ItemAdapter::setTags()`
+
+## 0.4.3
+
+### Fixed
+
+* Do not lose the data when you start using the `TaggablePSR6PoolAdapter`
+
+## 0.4.2
+
+### Changed
+
+* Updated version for integration tests
+* Made `TaggablePSR6PoolAdapter::getTags` protected instead of private
+
+## 0.4.1
+
+### Fixed
+
+* Saving an expired value should be the same as removing that value
+
+## 0.4.0
+
+This is a big BC break. The API is rewritten and how we store tags has changed. Each tag is a key to a list in the
+cache storage. The list contains keys to items that uses that tag.
+
+* The `TaggableItemInterface` is completely rewritten. It extends `CacheItemInterface` and has three methods: `getTags`, `setTags` and `addTag`.
+* The `TaggablePoolInterface` is also rewritten. It has a new `clearTags` function.
+* The `TaggablePoolTrait` has new methods to manipulate the list of tags.
+
+## 0.3.1
+
+No changelog before this version

+This repository has a adapter that makes any PSR-6 pool taggable. All PHPC ache pools support tagging out of the box. 
+Using tags allow you to tag related items, and then clear the cached data for that tag only. It is a part of the PHP Cache 
+organisation. To read about features like tagging and hierarchy support please read the shared documentation at [www.php-cache.com](http://www.php-cache.com).

+ * This adapter lets you make any PSR-6 cache pool taggable. If a pool is
+ * already taggable, it is simply returned by makeTaggable. Tags are stored
+ * either in the same cache pool, or a a separate pool, and both of these
+ * appoaches come with different caveats.
+ *
+ * A general caveat is that using this adapter reserves any cache key starting
+ * with '__tag.'.
+ *
+ * Using the same pool is precarious if your cache does LRU evictions of items
+ * even if they do not expire (as in e.g. memcached). If so, the tag item may
+ * be evicted without all of the tagged items having been evicted first,
+ * causing items to lose their tags.
+ *
+ * In order to mitigate this issue, you may use a separate, more persistent
+ * pool for your tag items. Do however note that if you are doing so, the
+ * entire pool is reserved for tags, as this pool is cleared whenever the
+ * main pool is cleared.

+# Container Interoperability

+
+## Deprecation warning!
+
+Starting Feb. 13th 2017, container-interop is officially deprecated in favor of [PSR-11](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-11-container.md).
+Container-interop has been the test-bed of PSR-11. From v1.2, container-interop directly extends PSR-11 interfaces.
+Therefore, all containers implementing container-interop are now *de-facto* compatible with PSR-11.
+
+- Projects implementing container-interop interfaces are encouraged to directly implement PSR-11 interfaces instead.
+- Projects consuming container-interop interfaces are very strongly encouraged to directly type-hint on PSR-11 interfaces, in order to be compatible with PSR-11 containers that are not compatible with container-interop.
+
+Regarding the delegate lookup feature, that is present in container-interop and not in PSR-11, the feature is actually a design pattern. It is therefore not deprecated. Documentation regarding this design pattern will be migrated from this repository into a separate website in the future.
+
+## About
+
+*container-interop* tries to identify and standardize features in *container* objects (service locators,
+dependency injection containers, etc.) to achieve interoperability.
+
+Through discussions and trials, we try to create a standard, made of common interfaces but also recommendations.
+
+If PHP projects that provide container implementations begin to adopt these common standards, then PHP
+applications and projects that use containers can depend on the common interfaces instead of specific
+implementations. This facilitates a high-level of interoperability and flexibility that allows users to consume
+*any* container implementation that can be adapted to these interfaces.
+
+The work done in this project is not officially endorsed by the [PHP-FIG](http://www.php-fig.org/), but it is being
+worked on by members of PHP-FIG and other good developers. We adhere to the spirit and ideals of PHP-FIG, and hope
+this project will pave the way for one or more future PSRs.
+
+
+## Installation
+
+You can install this package through Composer:
+
+```json
+composer require container-interop/container-interop
+```
+
+The packages adheres to the [SemVer](http://semver.org/) specification, and there will be full backward compatibility
+between minor versions.
+
+## Standards
+
+### Available
+
+- [`ContainerInterface`](src/Interop/Container/ContainerInterface.php).
+[Description](docs/ContainerInterface.md) [Meta Document](docs/ContainerInterface-meta.md).
+Describes the interface of a container that exposes methods to read its entries.
+- [*Delegate lookup feature*](docs/Delegate-lookup.md).
+[Meta Document](docs/Delegate-lookup-meta.md).
+Describes the ability for a container to delegate the lookup of its dependencies to a third-party container. This
+feature lets several containers work together in a single application.

+## Workflow
+
+Everyone is welcome to join and contribute.
+
+The general workflow looks like this:
+
+1. Someone opens a discussion (GitHub issue) to suggest an interface
+1. Feedback is gathered
+1. The interface is added to a development branch
+1. We release alpha versions so that the interface can be experimented with
+1. Discussions and edits ensue until the interface is deemed stable by a general consensus
+1. A new minor version of the package is released
+
+We try to not break BC by creating new interfaces instead of editing existing ones.
+
+While we currently work on interfaces, we are open to anything that might help towards interoperability, may that
+be code, best practices, etc.

+# ContainerInterface Meta Document
+
+## Introduction
+
+This document describes the process and discussions that lead to the `ContainerInterface`.
+Its goal is to explain the reasons behind each decision.
+
+## Goal
+
+The goal set by `ContainerInterface` is to standardize how frameworks and libraries make use of a
+container to obtain objects and parameters.
+
+By standardizing such a behavior, frameworks and libraries using the `ContainerInterface`
+could work with any compatible container.
+That would allow end users to choose their own container based on their own preferences.
+
+It is important to distinguish the two usages of a container:
+
+- configuring entries
+- fetching entries
+
+Most of the time, those two sides are not used by the same party.
+While it is often end users who tend to configure entries, it is generally the framework that fetch
+entries to build the application.
+
+This is why this interface focuses only on how entries can be fetched from a container.
+
+## Interface name
+
+The interface name has been thoroughly discussed and was decided by a vote.
+
+The list of options considered with their respective votes are:
+
+- `ContainerInterface`: +8
+- `ProviderInterface`: +2
+- `LocatorInterface`: 0
+- `ReadableContainerInterface`: -5
+- `ServiceLocatorInterface`: -6
+- `ObjectFactory`: -6
+- `ObjectStore`: -8
+- `ConsumerInterface`: -9
+
+[Full results of the vote](https://github.com/container-interop/container-interop/wiki/%231-interface-name:-Vote)
+
+The complete discussion can be read in [the issue #1](https://github.com/container-interop/container-interop/issues/1).
+
+## Interface methods
+
+The choice of which methods the interface would contain was made after a statistical analysis of existing containers.
+The results of this analysis are available [in this document](https://gist.github.com/mnapoli/6159681).
+
+The summary of the analysis showed that:
+
+- all containers offer a method to get an entry by its id
+- a large majority name such method `get()`
+- for all containers, the `get()` method has 1 mandatory parameter of type string
+- some containers have an optional additional argument for `get()`, but it doesn't have the same purpose between containers
+- a large majority of the containers offer a method to test if it can return an entry by its id
+- a majority name such method `has()`
+- for all containers offering `has()`, the method has exactly 1 parameter of type string
+- a large majority of the containers throw an exception rather than returning null when an entry is not found in `get()`
+- a large majority of the containers don't implement `ArrayAccess`
+
+The question of whether to include methods to define entries has been discussed in
+[issue #1](https://github.com/container-interop/container-interop/issues/1).
+It has been judged that such methods do not belong in the interface described here because it is out of its scope
+(see the "Goal" section).
+
+As a result, the `ContainerInterface` contains two methods:
+
+- `get()`, returning anything, with one mandatory string parameter. Should throw an exception if the entry is not found.
+- `has()`, returning a boolean, with one mandatory string parameter.
+
+### Number of parameters in `get()` method
+
+While `ContainerInterface` only defines one mandatory parameter in `get()`, it is not incompatible with
+existing containers that have additional optional parameters. PHP allows an implementation to offer more parameters
+as long as they are optional, because the implementation *does* satisfy the interface.
+
+This issue has been discussed in [issue #6](https://github.com/container-interop/container-interop/issues/6).
+
+### Type of the `$id` parameter
+
+The type of the `$id` parameter in `get()` and `has()` has been discussed in
+[issue #6](https://github.com/container-interop/container-interop/issues/6).
+While `string` is used in all the containers that were analyzed, it was suggested that allowing
+anything (such as objects) could allow containers to offer a more advanced query API.
+
+An example given was to use the container as an object builder. The `$id` parameter would then be an
+object that would describe how to create an instance.
+
+The conclusion of the discussion was that this was beyond the scope of getting entries from a container without
+knowing how the container provided them, and it was more fit for a factory.

+Container interface
+===================
+
+This document describes a common interface for dependency injection containers.
+
+The goal set by `ContainerInterface` is to standardize how frameworks and libraries make use of a
+container to obtain objects and parameters (called *entries* in the rest of this document).
+
+The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
+"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be
+interpreted as described in [RFC 2119][].
+
+The word `implementor` in this document is to be interpreted as someone
+implementing the `ContainerInterface` in a dependency injection-related library or framework.
+Users of dependency injections containers (DIC) are referred to as `user`.
+
+[RFC 2119]: http://tools.ietf.org/html/rfc2119
+
+1. Specification
+-----------------
+
+### 1.1 Basics
+
+- The `Interop\Container\ContainerInterface` exposes two methods : `get` and `has`.
+
+- `get` takes one mandatory parameter: an entry identifier. It MUST be a string.
+  A call to `get` can return anything (a *mixed* value), or throws an exception if the identifier
+  is not known to the container. Two successive calls to `get` with the same
+  identifier SHOULD return the same value. However, depending on the `implementor`
+  design and/or `user` configuration, different values might be returned, so
+  `user` SHOULD NOT rely on getting the same value on 2 successive calls.
+  While `ContainerInterface` only defines one mandatory parameter in `get()`, implementations
+  MAY accept additional optional parameters.
+
+- `has` takes one unique parameter: an entry identifier. It MUST return `true`
+  if an entry identifier is known to the container and `false` if it is not.
+  `has($id)` returning true does not mean that `get($id)` will not throw an exception.
+  It does however mean that `get($id)` will not throw a `NotFoundException`.
+
+### 1.2 Exceptions
+
+Exceptions directly thrown by the container MUST implement the
+[`Interop\Container\Exception\ContainerException`](../src/Interop/Container/Exception/ContainerException.php).
+
+A call to the `get` method with a non-existing id SHOULD throw a
+[`Interop\Container\Exception\NotFoundException`](../src/Interop/Container/Exception/NotFoundException.php).
+
+### 1.3 Additional features
+
+This section describes additional features that MAY be added to a container. Containers are not
+required to implement these features to respect the ContainerInterface.
+
+#### 1.3.1 Delegate lookup feature
+
+The goal of the *delegate lookup* feature is to allow several containers to share entries.
+Containers implementing this feature can perform dependency lookups in other containers.
+
+Containers implementing this feature will offer a greater lever of interoperability
+with other containers. Implementation of this feature is therefore RECOMMENDED.
+
+A container implementing this feature:
+
+- MUST implement the `ContainerInterface`
+- MUST provide a way to register a delegate container (using a constructor parameter, or a setter,
+  or any possible way). The delegate container MUST implement the `ContainerInterface`.
+
+When a container is configured to use a delegate container for dependencies:
+
+- Calls to the `get` method should only return an entry if the entry is part of the container.
+  If the entry is not part of the container, an exception should be thrown
+  (as requested by the `ContainerInterface`).
+- Calls to the `has` method should only return `true` if the entry is part of the container.
+  If the entry is not part of the container, `false` should be returned.
+- If the fetched entry has dependencies, **instead** of performing
+  the dependency lookup in the container, the lookup is performed on the *delegate container*.
+
+Important! By default, the lookup SHOULD be performed on the delegate container **only**, not on the container itself.
+
+It is however allowed for containers to provide exception cases for special entries, and a way to lookup
+into the same container (or another container) instead of the delegate container.
+
+2. Package
+----------
+
+The interfaces and classes described as well as relevant exception are provided as part of the
+[container-interop/container-interop](https://packagist.org/packages/container-interop/container-interop) package.
+
+3. `Interop\Container\ContainerInterface`
+-----------------------------------------
+
+```php

+     * @throws ContainerException Error while retrieving the entry.
+     *
+     * @return mixed Entry.
+     */
+    public function get($id);
+
+    /**
+     * Returns true if the container can return an entry for the given identifier.
+     * Returns false otherwise.
+     *
+     * `has($id)` returning true does not mean that `get($id)` will not throw an exception.
+     * It does however mean that `get($id)` will not throw a `NotFoundException`.
+     *
+     * @param string $id Identifier of the entry to look for.
+     *
+     * @return boolean
+     */
+    public function has($id);
+}
+```
+
+4. `Interop\Container\Exception\ContainerException`
+---------------------------------------------------
+
+```php
+<?php
+namespace Interop\Container\Exception;
+
+/**
+ * Base interface representing a generic exception in a container.
+ */
+interface ContainerException
+{
+}
+```
+
+5. `Interop\Container\Exception\NotFoundException`
+---------------------------------------------------
+
+```php
+<?php
+namespace Interop\Container\Exception;
+
+/**
+ * No entry was found in the container.
+ */
+interface NotFoundException extends ContainerException
+{
+}

+Delegate lookup feature Meta Document
+=====================================
+
+1. Summary
+----------
+
+This document describes the *delegate lookup feature*.
+Containers are not required to implement this feature to respect the `ContainerInterface`.
+However, containers implementing this feature will offer a greater lever of interoperability
+with other containers, allowing multiple containers to share entries in the same application.
+Implementation of this feature is therefore recommanded.
+
+2. Why Bother?
+--------------
+
+The [`ContainerInterface`](../src/Interop/Container/ContainerInterface.php) ([meta doc](ContainerInterface.md))
+standardizes how frameworks and libraries make use of a container to obtain objects and parameters.
+
+By standardizing such a behavior, frameworks and libraries relying on the `ContainerInterface`
+could work with any compatible container.
+That would allow end users to choose their own container based on their own preferences.
+
+The `ContainerInterface` is also enough if we want to have several containers side-by-side in the same
+application. For instance, this is what the [CompositeContainer](https://github.com/jeremeamia/acclimate-container/blob/master/src/CompositeContainer.php) 
+class of [Acclimate](https://github.com/jeremeamia/acclimate-container) is designed for:
+
+![Side by side containers](images/side_by_side_containers.png)
+
+However, an instance in container 1 cannot reference an instance in container 2.
+
+It would be better if an instance of container 1 could reference an instance in container 2,
+and the opposite should be true. 
+
+![Interoperating containers](images/interoperating_containers.png)
+
+In the sample above, entry 1 in container 1 is referencing entry 3 in container 2.
+
+3. Scope
+--------
+
+### 3.1 Goals
+
+The goal of the *delegate lookup* feature is to allow several containers to share entries.
+
+4. Approaches
+-------------
+
+### 4.1 Chosen Approach
+
+Containers implementing this feature can perform dependency lookups in other containers.
+
+A container implementing this feature:
+
+- must implement the `ContainerInterface`
+- must provide a way to register a *delegate container* (using a constructor parameter, or a setter, or any
+possible way). The *delegate container* must implement the `ContainerInterface`.
+
+When a *delegate container* is configured on a container:
+
+- Calls to the `get` method should only return an entry if the entry is part of the container.
+If the entry is not part of the container, an exception should be thrown (as required in the `ContainerInterface`).
+- Calls to the `has` method should only return *true* if the entry is part of the container.
+If the entry is not part of the container, *false* should be returned.
+ - Finally, the important part: if the entry we are fetching has dependencies,
+**instead** of perfoming the dependency lookup in the container, the lookup is performed on the *delegate container*.
+
+Important! By default, the lookup should be performed on the delegate container **only**, not on the container itself.
+
+It is however allowed for containers to provide exception cases for special entries, and a way to lookup into 
+the same container (or another container) instead of the delegate container.
+
+### 4.2 Typical usage
+
+The *delegate container* will usually be a composite container. A composite container is a container that
+contains several other containers. When performing a lookup on a composite container, the inner containers are 
+queried until one container returns an entry.
+An inner container implementing the *delegate lookup feature* will return entries it contains, but if these
+entries have dependencies, the dependencies lookup calls will be performed on the composite container, giving
+a chance to all containers to answer.
+
+Interestingly enough, the order in which containers are added in the composite container matters. Indeed,
+the first containers to be added in the composite container can "override" the entries of containers with
+lower priority.
+
+![Containers priority](images/priority.png)
+
+In the example above, "container 2" contains a controller "myController" and the controller is referencing an 
+"entityManager" entry. "Container 1" contains also an entry named "entityManager".
+Without the *delegate lookup* feature, when requesting the "myController" instance to container 2, it would take 
+in charge the instanciation of both entries.
+
+However, using the *delegate lookup* feature, here is what happens when we ask the composite container for the 
+"myController" instance:
+
+- The composite container asks container 1 if if contains the "myController" instance. The answer is no.
+- The composite container asks container 2 if if contains the "myController" instance. The answer is yes.
+- The composite container performs a `get` call on container 2 for the "myController" instance.
+- Container 2 sees that "myController" has a dependency on "entityManager".
+- Container 2 delegates the lookup of "entityManager" to the composite container.
+- The composite container asks container 1 if if contains the "entityManager" instance. The answer is yes.
+- The composite container performs a `get` call on container 1 for the "entityManager" instance.
+
+In the end, we get a controller instanciated by container 2 that references an entityManager instanciated
+by container 1.
+
+### 4.3 Alternative: the fallback strategy
+
+The first proposed approach we tried was to perform all the lookups in the "local" container,
+and if a lookup fails in the container, to use the delegate container. In this scenario, the
+delegate container is used in "fallback" mode.
+
+This strategy has been described in @moufmouf blog post: http://mouf-php.com/container-interop-whats-next (solution 1).
+It was also discussed [here](https://github.com/container-interop/container-interop/pull/8#issuecomment-33570697) and
+[here](https://github.com/container-interop/container-interop/pull/20#issuecomment-56599631).
+
+Problems with this strategy:
+
+- Heavy problem regarding infinite loops
+- Unable to overload a container entry with the delegate container entry
+
+### 4.4 Alternative: force implementing an interface
+
+The first proposed approach was to develop a `ParentAwareContainerInterface` interface.
+It was proposed here: https://github.com/container-interop/container-interop/pull/8
+
+The interface would have had the behaviour of the delegate lookup feature but would have forced the addition of
+a `setParentContainter` method:
+
+```php
+interface ParentAwareContainerInterface extends ReadableContainerInterface {
+    /**
+     * Sets the parent container associated to that container. This container will call
+     * the parent container to fetch dependencies.
+     *
+     * @param ContainerInterface $container
+     */
+    public function setParentContainer(ContainerInterface $container);
+}
+```
+
+The interface idea was first questioned by @Ocramius [here](https://github.com/container-interop/container-interop/pull/8#issuecomment-51721777).
+@Ocramius expressed the idea that an interface should not contain setters, otherwise, it is forcing implementation
+details on the class implementing the interface. 
+Then @mnapoli made a proposal for a "convention" [here](https://github.com/container-interop/container-interop/pull/8#issuecomment-51841079),
+this idea was further discussed until all participants in the discussion agreed to remove the interface idea
+and replace it with a "standard" feature.
+
+**Pros:**
+
+If we had had an interface, we could have delegated the registration of the delegate/composite container to the
+the delegate/composite container itself.
+For instance:
+
+```php
+$containerA = new ContainerA();
+$containerB = new ContainerB();
+
+$compositeContainer = new CompositeContainer([$containerA, $containerB]);
+
+// The call to 'setParentContainer' is delegated to the CompositeContainer
+// It is not the responsibility of the user anymore.
+class CompositeContainer {
+	...
+	
+	public function __construct($containers) {
+		foreach ($containers as $container) {
+			if ($container instanceof ParentAwareContainerInterface) {
+				$container->setParentContainer($this);
+			}
+		}
+		...
+	}
+}
+
+``` 
+
+**Cons:**
+
+Cons have been extensively discussed [here](https://github.com/container-interop/container-interop/pull/8#issuecomment-51721777).
+Basically, forcing a setter into an interface is a bad idea. Setters are similar to constructor arguments,
+and it's a bad idea to standardize a constructor: how the delegate container is configured into a container is an implementation detail. This outweights the benefits of the interface.
+
+### 4.4 Alternative: no exception case for delegate lookups
+
+Originally, the proposed wording for delegate lookup calls was:
+
+> Important! The lookup MUST be performed on the delegate container **only**, not on the container itself.
+
+This was later replaced by:
+
+> Important! By default, the lookup SHOULD be performed on the delegate container **only**, not on the container itself.
+>
+> It is however allowed for containers to provide exception cases for special entries, and a way to lookup 
+> into the same container (or another container) instead of the delegate container.
+
+Exception cases have been allowed to avoid breaking dependencies with some services that must be provided
+by the container (on @njasm proposal). This was proposed here: https://github.com/container-interop/container-interop/pull/20#issuecomment-56597235
+
+### 4.5 Alternative: having one of the containers act as the composite container
+
+In real-life scenarios, we usually have a big framework (Symfony 2, Zend Framework 2, etc...) and we want to
+add another DI container to this container. Most of the time, the "big" framework will be responsible for
+creating the controller's instances, using it's own DI container. Until *container-interop* is fully adopted,
+the "big" framework will not be aware of the existence of a composite container that it should use instead
+of its own container.
+
+For this real-life use cases, @mnapoli and @moufmouf proposed to extend the "big" framework's DI container
+to make it act as a composite container.
+
+This has been discussed [here](https://github.com/container-interop/container-interop/pull/8#issuecomment-40367194) 
+and [here](http://mouf-php.com/container-interop-whats-next#solution4).
+
+This was implemented in Symfony 2 using:
+
+- [interop.symfony.di](https://github.com/thecodingmachine/interop.symfony.di/tree/v0.1.0)
+- [framework interop](https://github.com/mnapoli/framework-interop/)
+
+This was implemented in Silex using:
+
+- [interop.silex.di](https://github.com/thecodingmachine/interop.silex.di)
+
+Having a container act as the composite container is not part of the delegate lookup standard because it is
+simply a temporary design pattern used to make existing frameworks that do not support yet ContainerInterop
+play nice with other DI containers.
+

+Delegate lookup feature
+=======================
+
+This document describes a standard for dependency injection containers.
+
+The goal set by the *delegate lookup* feature is to allow several containers to share entries.
+Containers implementing this feature can perform dependency lookups in other containers.
+
+Containers implementing this feature will offer a greater lever of interoperability
+with other containers. Implementation of this feature is therefore RECOMMENDED.
+
+The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
+"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be
+interpreted as described in [RFC 2119][].
+
+The word `implementor` in this document is to be interpreted as someone
+implementing the delegate lookup feature in a dependency injection-related library or framework.
+Users of dependency injections containers (DIC) are referred to as `user`.
+
+[RFC 2119]: http://tools.ietf.org/html/rfc2119
+
+1. Vocabulary
+-------------
+
+In a dependency injection container, the container is used to fetch entries.
+Entries can have dependencies on other entries. Usually, these other entries are fetched by the container.
+
+The *delegate lookup* feature is the ability for a container to fetch dependencies in
+another container. In the rest of the document, the word "container" will reference the container
+implemented by the implementor. The word "delegate container" will reference the container we are
+fetching the dependencies from.
+
+2. Specification
+----------------
+
+A container implementing the *delegate lookup* feature:
+
+- MUST implement the [`ContainerInterface`](ContainerInterface.md)
+- MUST provide a way to register a delegate container (using a constructor parameter, or a setter,
+  or any possible way). The delegate container MUST implement the [`ContainerInterface`](ContainerInterface.md).
+
+When a container is configured to use a delegate container for dependencies:
+
+- Calls to the `get` method should only return an entry if the entry is part of the container.
+  If the entry is not part of the container, an exception should be thrown
+  (as requested by the [`ContainerInterface`](ContainerInterface.md)).
+- Calls to the `has` method should only return `true` if the entry is part of the container.
+  If the entry is not part of the container, `false` should be returned.
+- If the fetched entry has dependencies, **instead** of performing
+  the dependency lookup in the container, the lookup is performed on the *delegate container*.
+
+Important: By default, the dependency lookups SHOULD be performed on the delegate container **only**, not on the container itself.
+
+It is however allowed for containers to provide exception cases for special entries, and a way to lookup
+into the same container (or another container) instead of the delegate container.
+
+3. Package / Interface
+----------------------
+
+This feature is not tied to any code, interface or package.

+# Upgrade to 1.4
+
+## Minor BC Break: `Doctrine\Common\Cache\FileCache#$extension` is now `private`.
+
+If you need to override the value of `Doctrine\Common\Cache\FileCache#$extension`, then use the
+second parameter of `Doctrine\Common\Cache\FileCache#__construct()` instead of overriding
+the property in your own implementation.
+
+## Minor BC Break: file based caches paths changed
+
+`Doctrine\Common\Cache\FileCache`, `Doctrine\Common\Cache\PhpFileCache` and
+`Doctrine\Common\Cache\FilesystemCache` are using a different cache paths structure.
+
+If you rely on warmed up caches for deployments, consider that caches generated
+with `doctrine/cache` `<1.4` are not compatible with the new directory structure,
+and will be ignored.

+# Instantiator
+
+This library provides a way of avoiding usage of constructors when instantiating PHP classes.

+
+## Installation
+
+The suggested installation method is via [composer](https://getcomposer.org/):
+
+```sh
+php composer.phar require "doctrine/instantiator:~1.0.3"
+```
+
+## Usage
+
+The instantiator is able to create new instances of any class without using the constructor or any API of the class
+itself:
+
+```php
+$instantiator = new \Doctrine\Instantiator\Instantiator();
+
+$instance = $instantiator->instantiate(\My\ClassName\Here::class);
+```
+
+## Contributing
+
+Please read the [CONTRIBUTING.md](CONTRIBUTING.md) contents if you wish to help out!
+
+## Credits
+
+This library was migrated from [ocramius/instantiator](https://github.com/Ocramius/Instantiator), which
+has been donated to the doctrine organization, and which is now deprecated in favour of this package.

+PHP-JWT
+=======
+A simple library to encode and decode JSON Web Tokens (JWT) in PHP, conforming to [RFC 7519](https://tools.ietf.org/html/rfc7519).
+
+Installation
+------------
+
+Use composer to manage your dependencies and download PHP-JWT:
+
+```bash
+composer require firebase/php-jwt
+```
+
+Example
+-------
+```php
+<?php
+use \Firebase\JWT\JWT;
+
+$key = "example_key";
+$token = array(
+    "iss" => "http://example.org",
+    "aud" => "http://example.com",
+    "iat" => 1356999524,
+    "nbf" => 1357000000
+);
+
+/**
+ * IMPORTANT:
+ * You must specify supported algorithms for your application. See
+ * https://tools.ietf.org/html/draft-ietf-jose-json-web-algorithms-40
+ * for a list of spec-compliant algorithms.
+ */
+$jwt = JWT::encode($token, $key);
+$decoded = JWT::decode($jwt, $key, array('HS256'));
+
+print_r($decoded);
+
+/*
+ NOTE: This will now be an object instead of an associative array. To get
+ an associative array, you will need to cast it as such:
+*/
+
+$decoded_array = (array) $decoded;
+
+/**
+ * You can add a leeway to account for when there is a clock skew times between
+ * the signing and verifying servers. It is recommended that this leeway should
+ * not be bigger than a few minutes.
+ *
+ * Source: http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#nbfDef
+ */

+
+Tests
+-----
+Run the tests using phpunit:
+
+```bash
+$ pear install PHPUnit
+$ phpunit --configuration phpunit.xml.dist
+PHPUnit 3.7.10 by Sebastian Bergmann.
+.....
+Time: 0 seconds, Memory: 2.50Mb
+OK (5 tests, 5 assertions)
+```
+
+New Lines in private keys
+-----
+
+If your private key contains `\n` characters, be sure to wrap it in double quotes `""`
+and not single quotes `''` in order to properly interpret the escaped characters.

+
+## 6.0.2 - 2015-07-04
+
+* Fixed a memory leak in the curl handlers in which references to callbacks
+  were not being removed by `curl_reset`.
+* Cookies are now extracted properly before redirects.
+* Cookies now allow more character ranges.
+* Decoded Content-Encoding responses are now modified to correctly reflect
+  their state if the encoding was automatically removed by a handler. This
+  means that the `Content-Encoding` header may be removed an the
+  `Content-Length` modified to reflect the message size after removing the
+  encoding.
+* Added a more explicit error message when trying to use `form_params` and
+  `multipart` in the same request.
+* Several fixes for HHVM support.
+* Functions are now conditionally required using an additional level of
+  indirection to help with global Composer installations.
+
+## 6.0.1 - 2015-05-27
+
+* Fixed a bug with serializing the `query` request option where the `&`
+  separator was missing.
+* Added a better error message for when `body` is provided as an array. Please
+  use `form_params` or `multipart` instead.
+* Various doc fixes.
+
+## 6.0.0 - 2015-05-26
+
+* See the UPGRADING.md document for more information.
+* Added `multipart` and `form_params` request options.
+* Added `synchronous` request option.
+* Added the `on_headers` request option.
+* Fixed `expect` handling.
+* No longer adding default middlewares in the client ctor. These need to be
+  present on the provided handler in order to work.
+* Requests are no longer initiated when sending async requests with the
+  CurlMultiHandler. This prevents unexpected recursion from requests completing
+  while ticking the cURL loop.
+* Removed the semantics of setting `default` to `true`. This is no longer
+  required now that the cURL loop is not ticked for async requests.
+* Added request and response logging middleware.
+* No longer allowing self signed certificates when using the StreamHandler.
+* Ensuring that `sink` is valid if saving to a file.
+* Request exceptions now include a "handler context" which provides handler
+  specific contextual information.
+* Added `GuzzleHttp\RequestOptions` to allow request options to be applied
+  using constants.
+* `$maxHandles` has been removed from CurlMultiHandler.
+* `MultipartPostBody` is now part of the `guzzlehttp/psr7` package.
+
+## 5.3.0 - 2015-05-19
+
+* Mock now supports `save_to`
+* Marked `AbstractRequestEvent::getTransaction()` as public.
+* Fixed a bug in which multiple headers using different casing would overwrite
+  previous headers in the associative array.
+* Added `Utils::getDefaultHandler()`
+* Marked `GuzzleHttp\Client::getDefaultUserAgent` as deprecated.
+* URL scheme is now always lowercased.
+
+## 6.0.0-beta.1
+
+* Requires PHP >= 5.5
+* Updated to use PSR-7
+  * Requires immutable messages, which basically means an event based system
+    owned by a request instance is no longer possible.
+  * Utilizing the [Guzzle PSR-7 package](https://github.com/guzzle/psr7).
+  * Removed the dependency on `guzzlehttp/streams`. These stream abstractions
+    are available in the `guzzlehttp/psr7` package under the `GuzzleHttp\Psr7`
+    namespace.
+* Added middleware and handler system
+  * Replaced the Guzzle event and subscriber system with a middleware system.
+  * No longer depends on RingPHP, but rather places the HTTP handlers directly
+    in Guzzle, operating on PSR-7 messages.
+  * Retry logic is now encapsulated in `GuzzleHttp\Middleware::retry`, which
+    means the `guzzlehttp/retry-subscriber` is now obsolete.
+  * Mocking responses is now handled using `GuzzleHttp\Handler\MockHandler`.
+* Asynchronous responses
+  * No longer supports the `future` request option to send an async request.
+    Instead, use one of the `*Async` methods of a client (e.g., `requestAsync`,
+    `getAsync`, etc.).
+  * Utilizing `GuzzleHttp\Promise` instead of React's promise library to avoid
+    recursion required by chaining and forwarding react promises. See
+    https://github.com/guzzle/promises
+  * Added `requestAsync` and `sendAsync` to send request asynchronously.
+  * Added magic methods for `getAsync()`, `postAsync()`, etc. to send requests
+    asynchronously.
+* Request options
+  * POST and form updates
+    * Added the `form_fields` and `form_files` request options.
+    * Removed the `GuzzleHttp\Post` namespace.
+    * The `body` request option no longer accepts an array for POST requests.
+  * The `exceptions` request option has been deprecated in favor of the
+    `http_errors` request options.
+  * The `save_to` request option has been deprecated in favor of `sink` request
+    option.
+* Clients no longer accept an array of URI template string and variables for
+  URI variables. You will need to expand URI templates before passing them
+  into a client constructor or request method.
+* Client methods `get()`, `post()`, `put()`, `patch()`, `options()`, etc. are
+  now magic methods that will send synchronous requests.
+* Replaced `Utils.php` with plain functions in `functions.php`.
+* Removed `GuzzleHttp\Collection`.
+* Removed `GuzzleHttp\BatchResults`. Batched pool results are now returned as
+  an array.
+* Removed `GuzzleHttp\Query`. Query string handling is now handled using an
+  associative array passed into the `query` request option. The query string
+  is serialized using PHP's `http_build_query`. If you need more control, you
+  can pass the query string in as a string.
+* `GuzzleHttp\QueryParser` has been replaced with the
+  `GuzzleHttp\Psr7\parse_query`.
+
+## 5.2.0 - 2015-01-27
+
+* Added `AppliesHeadersInterface` to make applying headers to a request based
+  on the body more generic and not specific to `PostBodyInterface`.
+* Reduced the number of stack frames needed to send requests.
+* Nested futures are now resolved in the client rather than the RequestFsm
+* Finishing state transitions is now handled in the RequestFsm rather than the
+  RingBridge.
+* Added a guard in the Pool class to not use recursion for request retries.
+
+## 5.1.0 - 2014-12-19
+
+* Pool class no longer uses recursion when a request is intercepted.
+* The size of a Pool can now be dynamically adjusted using a callback.
+  See https://github.com/guzzle/guzzle/pull/943.
+* Setting a request option to `null` when creating a request with a client will
+  ensure that the option is not set. This allows you to overwrite default
+  request options on a per-request basis.
+  See https://github.com/guzzle/guzzle/pull/937.
+* Added the ability to limit which protocols are allowed for redirects by
+  specifying a `protocols` array in the `allow_redirects` request option.
+* Nested futures due to retries are now resolved when waiting for synchronous
+  responses. See https://github.com/guzzle/guzzle/pull/947.
+* `"0"` is now an allowed URI path. See
+  https://github.com/guzzle/guzzle/pull/935.
+* `Query` no longer typehints on the `$query` argument in the constructor,
+  allowing for strings and arrays.
+* Exceptions thrown in the `end` event are now correctly wrapped with Guzzle
+  specific exceptions if necessary.
+
+## 5.0.3 - 2014-11-03
+
+This change updates query strings so that they are treated as un-encoded values
+by default where the value represents an un-encoded value to send over the
+wire. A Query object then encodes the value before sending over the wire. This
+means that even value query string values (e.g., ":") are url encoded. This
+makes the Query class match PHP's http_build_query function. However, if you
+want to send requests over the wire using valid query string characters that do
+not need to be encoded, then you can provide a string to Url::setQuery() and
+pass true as the second argument to specify that the query string is a raw
+string that should not be parsed or encoded (unless a call to getQuery() is
+subsequently made, forcing the query-string to be converted into a Query
+object).
+
+## 5.0.2 - 2014-10-30
+
+* Added a trailing `\r\n` to multipart/form-data payloads. See
+  https://github.com/guzzle/guzzle/pull/871
+* Added a `GuzzleHttp\Pool::send()` convenience method to match the docs.
+* Status codes are now returned as integers. See
+  https://github.com/guzzle/guzzle/issues/881
+* No longer overwriting an existing `application/x-www-form-urlencoded` header
+  when sending POST requests, allowing for customized headers. See
+  https://github.com/guzzle/guzzle/issues/877
+* Improved path URL serialization.
+
+  * No longer double percent-encoding characters in the path or query string if
+    they are already encoded.
+  * Now properly encoding the supplied path to a URL object, instead of only
+    encoding ' ' and '?'.
+  * Note: This has been changed in 5.0.3 to now encode query string values by
+    default unless the `rawString` argument is provided when setting the query
+    string on a URL: Now allowing many more characters to be present in the
+    query string without being percent encoded. See http://tools.ietf.org/html/rfc3986#appendix-A
+
+## 5.0.1 - 2014-10-16
+
+Bugfix release.
+
+* Fixed an issue where connection errors still returned response object in
+  error and end events event though the response is unusable. This has been
+  corrected so that a response is not returned in the `getResponse` method of
+  these events if the response did not complete. https://github.com/guzzle/guzzle/issues/867
+* Fixed an issue where transfer statistics were not being populated in the
+  RingBridge. https://github.com/guzzle/guzzle/issues/866
+
+## 5.0.0 - 2014-10-12
+
+Adding support for non-blocking responses and some minor API cleanup.
+
+### New Features
+
+* Added support for non-blocking responses based on `guzzlehttp/guzzle-ring`.
+* Added a public API for creating a default HTTP adapter.
+* Updated the redirect plugin to be non-blocking so that redirects are sent
+  concurrently. Other plugins like this can now be updated to be non-blocking.
+* Added a "progress" event so that you can get upload and download progress
+  events.
+* Added `GuzzleHttp\Pool` which implements FutureInterface and transfers
+  requests concurrently using a capped pool size as efficiently as possible.
+* Added `hasListeners()` to EmitterInterface.
+* Removed `GuzzleHttp\ClientInterface::sendAll` and marked
+  `GuzzleHttp\Client::sendAll` as deprecated (it's still there, just not the
+  recommended way).
+
+### Breaking changes
+
+The breaking changes in this release are relatively minor. The biggest thing to
+look out for is that request and response objects no longer implement fluent
+interfaces.
+
+* Removed the fluent interfaces (i.e., `return $this`) from requests,
+  responses, `GuzzleHttp\Collection`, `GuzzleHttp\Url`,
+  `GuzzleHttp\Query`, `GuzzleHttp\Post\PostBody`, and
+  `GuzzleHttp\Cookie\SetCookie`. This blog post provides a good outline of
+  why I did this: http://ocramius.github.io/blog/fluent-interfaces-are-evil/.
+  This also makes the Guzzle message interfaces compatible with the current
+  PSR-7 message proposal.
+* Removed "functions.php", so that Guzzle is truly PSR-4 compliant. Except
+  for the HTTP request functions from function.php, these functions are now
+  implemented in `GuzzleHttp\Utils` using camelCase. `GuzzleHttp\json_decode`
+  moved to `GuzzleHttp\Utils::jsonDecode`. `GuzzleHttp\get_path` moved to
+  `GuzzleHttp\Utils::getPath`. `GuzzleHttp\set_path` moved to
+  `GuzzleHttp\Utils::setPath`. `GuzzleHttp\batch` should now be
+  `GuzzleHttp\Pool::batch`, which returns an `objectStorage`. Using functions.php
+  caused problems for many users: they aren't PSR-4 compliant, require an
+  explicit include, and needed an if-guard to ensure that the functions are not
+  declared multiple times.
+* Rewrote adapter layer.
+    * Removing all classes from `GuzzleHttp\Adapter`, these are now
+      implemented as callables that are stored in `GuzzleHttp\Ring\Client`.
+    * Removed the concept of "parallel adapters". Sending requests serially or
+      concurrently is now handled using a single adapter.
+    * Moved `GuzzleHttp\Adapter\Transaction` to `GuzzleHttp\Transaction`. The
+      Transaction object now exposes the request, response, and client as public
+      properties. The getters and setters have been removed.
+* Removed the "headers" event. This event was only useful for changing the
+  body a response once the headers of the response were known. You can implement
+  a similar behavior in a number of ways. One example might be to use a
+  FnStream that has access to the transaction being sent. For example, when the
+  first byte is written, you could check if the response headers match your
+  expectations, and if so, change the actual stream body that is being
+  written to.
+* Removed the `asArray` parameter from
+  `GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+  value as an array, then use the newly added `getHeaderAsArray()` method of
+  `MessageInterface`. This change makes the Guzzle interfaces compatible with
+  the PSR-7 interfaces.
+* `GuzzleHttp\Message\MessageFactory` no longer allows subclasses to add
+  custom request options using double-dispatch (this was an implementation
+  detail). Instead, you should now provide an associative array to the
+  constructor which is a mapping of the request option name mapping to a
+  function that applies the option value to a request.
+* Removed the concept of "throwImmediately" from exceptions and error events.
+  This control mechanism was used to stop a transfer of concurrent requests
+  from completing. This can now be handled by throwing the exception or by
+  cancelling a pool of requests or each outstanding future request individually.
+* Updated to "GuzzleHttp\Streams" 3.0.
+    * `GuzzleHttp\Stream\StreamInterface::getContents()` no longer accepts a
+      `maxLen` parameter. This update makes the Guzzle streams project
+      compatible with the current PSR-7 proposal.
+    * `GuzzleHttp\Stream\Stream::__construct`,
+      `GuzzleHttp\Stream\Stream::factory`, and
+      `GuzzleHttp\Stream\Utils::create` no longer accept a size in the second
+      argument. They now accept an associative array of options, including the
+      "size" key and "metadata" key which can be used to provide custom metadata.
+
+## 4.2.2 - 2014-09-08
+
+* Fixed a memory leak in the CurlAdapter when reusing cURL handles.
+* No longer using `request_fulluri` in stream adapter proxies.
+* Relative redirects are now based on the last response, not the first response.
+
+## 4.2.1 - 2014-08-19
+
+* Ensuring that the StreamAdapter does not always add a Content-Type header
+* Adding automated github releases with a phar and zip
+
+## 4.2.0 - 2014-08-17
+
+* Now merging in default options using a case-insensitive comparison.
+  Closes https://github.com/guzzle/guzzle/issues/767
+* Added the ability to automatically decode `Content-Encoding` response bodies
+  using the `decode_content` request option. This is set to `true` by default
+  to decode the response body if it comes over the wire with a
+  `Content-Encoding`. Set this value to `false` to disable decoding the
+  response content, and pass a string to provide a request `Accept-Encoding`
+  header and turn on automatic response decoding. This feature now allows you
+  to pass an `Accept-Encoding` header in the headers of a request but still
+  disable automatic response decoding.
+  Closes https://github.com/guzzle/guzzle/issues/764
+* Added the ability to throw an exception immediately when transferring
+  requests in parallel. Closes https://github.com/guzzle/guzzle/issues/760
+* Updating guzzlehttp/streams dependency to ~2.1
+* No longer utilizing the now deprecated namespaced methods from the stream
+  package.
+
+## 4.1.8 - 2014-08-14
+
+* Fixed an issue in the CurlFactory that caused setting the `stream=false`
+  request option to throw an exception.
+  See: https://github.com/guzzle/guzzle/issues/769
+* TransactionIterator now calls rewind on the inner iterator.
+  See: https://github.com/guzzle/guzzle/pull/765
+* You can now set the `Content-Type` header to `multipart/form-data`
+  when creating POST requests to force multipart bodies.
+  See https://github.com/guzzle/guzzle/issues/768
+
+## 4.1.7 - 2014-08-07
+
+* Fixed an error in the HistoryPlugin that caused the same request and response
+  to be logged multiple times when an HTTP protocol error occurs.
+* Ensuring that cURL does not add a default Content-Type when no Content-Type
+  has been supplied by the user. This prevents the adapter layer from modifying
+  the request that is sent over the wire after any listeners may have already
+  put the request in a desired state (e.g., signed the request).
+* Throwing an exception when you attempt to send requests that have the
+  "stream" set to true in parallel using the MultiAdapter.
+* Only calling curl_multi_select when there are active cURL handles. This was
+  previously changed and caused performance problems on some systems due to PHP
+  always selecting until the maximum select timeout.
+* Fixed a bug where multipart/form-data POST fields were not correctly
+  aggregated (e.g., values with "&").
+
+## 4.1.6 - 2014-08-03
+
+* Added helper methods to make it easier to represent messages as strings,
+  including getting the start line and getting headers as a string.
+
+## 4.1.5 - 2014-08-02
+
+* Automatically retrying cURL "Connection died, retrying a fresh connect"
+  errors when possible.
+* cURL implementation cleanup
+* Allowing multiple event subscriber listeners to be registered per event by
+  passing an array of arrays of listener configuration.
+
+## 4.1.4 - 2014-07-22
+
+* Fixed a bug that caused multi-part POST requests with more than one field to
+  serialize incorrectly.
+* Paths can now be set to "0"
+* `ResponseInterface::xml` now accepts a `libxml_options` option and added a
+  missing default argument that was required when parsing XML response bodies.
+* A `save_to` stream is now created lazily, which means that files are not
+  created on disk unless a request succeeds.
+
+## 4.1.3 - 2014-07-15
+
+* Various fixes to multipart/form-data POST uploads
+* Wrapping function.php in an if-statement to ensure Guzzle can be used
+  globally and in a Composer install
+* Fixed an issue with generating and merging in events to an event array
+* POST headers are only applied before sending a request to allow you to change
+  the query aggregator used before uploading
+* Added much more robust query string parsing
+* Fixed various parsing and normalization issues with URLs
+* Fixing an issue where multi-valued headers were not being utilized correctly
+  in the StreamAdapter
+
+## 4.1.2 - 2014-06-18
+
+* Added support for sending payloads with GET requests
+
+## 4.1.1 - 2014-06-08

+## 3.7.0 - 2013-06-10
+
+* See UPGRADING.md for more information on how to upgrade.
+* Requests now support the ability to specify an array of $options when creating a request to more easily modify a
+  request. You can pass a 'request.options' configuration setting to a client to apply default request options to
+  every request created by a client (e.g. default query string variables, headers, curl options, etc.).
+* Added a static facade class that allows you to use Guzzle with static methods and mount the class to `\Guzzle`.
+  See `Guzzle\Http\StaticClient::mount`.
+* Added `command.request_options` to `Guzzle\Service\Command\AbstractCommand` to pass request options to requests
+      created by a command (e.g. custom headers, query string variables, timeout settings, etc.).
+* Stream size in `Guzzle\Stream\PhpStreamRequestFactory` will now be set if Content-Length is returned in the
+  headers of a response
+* Added `Guzzle\Common\Collection::setPath($path, $value)` to set a value into an array using a nested key
+  (e.g. `$collection->setPath('foo/baz/bar', 'test'); echo $collection['foo']['bar']['bar'];`)
+* ServiceBuilders now support storing and retrieving arbitrary data
+* CachePlugin can now purge all resources for a given URI
+* CachePlugin can automatically purge matching cached items when a non-idempotent request is sent to a resource

+* `Guzzle\Common\Exception\ExceptionCollection` now creates a more readable exception message
+* Fixing BC break: Added back the MonologLogAdapter implementation rather than extending from PsrLog so that older
+  Symfony users can still use the old version of Monolog.
+* Fixing BC break: Added the implementation back in for `Guzzle\Http\Message\AbstractMessage::getTokenizedHeader()`.
+  Now triggering an E_USER_DEPRECATED warning when used. Use `$message->getHeader()->parseParams()`.
+* Several performance improvements to `Guzzle\Common\Collection`
+* Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+* Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+* Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+* Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+* Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+* Added `Guzzle\Stream\StreamInterface::isRepeatable`
+* Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or

+* Removed `Guzzle\Http\Message\RequestInterface::isRedirect`
+* Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+* You can now enable E_USER_DEPRECATED warnings to see if you are using a deprecated method by setting
+  `Guzzle\Common\Version::$emitWarnings` to true.
+* Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use
+      `$request->getResponseBody()->isRepeatable()` instead.

+  `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+* Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+* Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+* Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+* Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand.
+  These will work through Guzzle 4.0
+* Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use [request.options][params].
+* Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+* Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use $client->getConfig()->getPath('request.options/headers')`.
+* Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use $client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`.
+* Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+* Marked `Guzzle\Common\Collection::inject()` as deprecated.
+* Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest');`
+* CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+* Always setting X-cache headers on cached responses
+* Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+* `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+* `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+* `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`

+  CanCacheStrategyInterface $canCache = null)`
+* Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+## 3.6.0 - 2013-05-29
+
+* ServiceDescription now implements ToArrayInterface
+* Added command.hidden_params to blacklist certain headers from being treated as additionalParameters
+* Guzzle can now correctly parse incomplete URLs
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+* Added the ability to cast Model objects to a string to view debug information.
+
+## 3.5.0 - 2013-05-13
+
+* Bug: Fixed a regression so that request responses are parsed only once per oncomplete event rather than multiple times
+* Bug: Better cleanup of one-time events across the board (when an event is meant to fire once, it will now remove
+  itself from the EventDispatcher)
+* Bug: `Guzzle\Log\MessageFormatter` now properly writes "total_time" and "connect_time" values
+* Bug: Cloning an EntityEnclosingRequest now clones the EntityBody too
+* Bug: Fixed an undefined index error when parsing nested JSON responses with a sentAs parameter that reference a
+  non-existent key
+* Bug: All __call() method arguments are now required (helps with mocking frameworks)
+* Deprecating Response::getRequest() and now using a shallow clone of a request object to remove a circular reference
+  to help with refcount based garbage collection of resources created by sending a request
+* Deprecating ZF1 cache and log adapters. These will be removed in the next major version.
+* Deprecating `Response::getPreviousResponse()` (method signature still exists, but it's deprecated). Use the
+  HistoryPlugin for a history.
+* Added a `responseBody` alias for the `response_body` location
+* Refactored internals to no longer rely on Response::getRequest()
+* HistoryPlugin can now be cast to a string
+* HistoryPlugin now logs transactions rather than requests and responses to more accurately keep track of the requests
+  and responses that are sent over the wire
+* Added `getEffectiveUrl()` and `getRedirectCount()` to Response objects
+
+## 3.4.3 - 2013-04-30
+

+* LogPlugin now writes to php://output when STDERR is undefined
+* Added the ability to set multiple POST files for the same key in a single call
+* application/x-www-form-urlencoded POSTs now use the utf-8 charset by default
+* Added the ability to queue CurlExceptions to the MockPlugin
+* Cleaned up how manual responses are queued on requests (removed "queued_response" and now using request.before_send)
+* Configuration loading now allows remote files
+
+## 3.4.1 - 2013-04-16
+
+* Large refactoring to how CurlMulti handles work. There is now a proxy that sits in front of a pool of CurlMulti
+  handles. This greatly simplifies the implementation, fixes a couple bugs, and provides a small performance boost.
+* Exceptions are now properly grouped when sending requests in parallel
+* Redirects are now properly aggregated when a multi transaction fails
+* Redirects now set the response on the original object even in the event of a failure
+* Bug fix: Model names are now properly set even when using $refs
+* Added support for PHP 5.5's CurlFile to prevent warnings with the deprecated @ syntax
+* Added support for oauth_callback in OAuth signatures
+* Added support for oauth_verifier in OAuth signatures
+* Added support to attempt to retrieve a command first literally, then ucfirst, the with inflection
+

+* Bug fix: Fixed "array to string" error when validating a union of types in a service description
+* Bug fix: Removed code that attempted to determine the size of a stream when data is written to the stream
+* Bug fix: Not including an `oauth_token` if the value is null in the OauthPlugin.
+* Bug fix: Now correctly aggregating successful requests and failed requests in CurlMulti when a redirect occurs.
+* The new default CURLOPT_TIMEOUT setting has been increased to 150 seconds so that Guzzle works on poor connections.
+* Added a feature to EntityEnclosingRequest::setBody() that will automatically set the Content-Type of the request if
+  the Content-Type can be determined based on the entity body or the path of the request.
+* Added the ability to overwrite configuration settings in a client when grabbing a throwaway client from a builder.
+* Added support for a PSR-3 LogAdapter.
+* Added a `command.after_prepare` event
+* Added `oauth_callback` parameter to the OauthPlugin
+* Added the ability to create a custom stream class when using a stream factory
+* Added a CachingEntityBody decorator
+* Added support for `additionalParameters` in service descriptions to define how custom parameters are serialized.
+* The bundled SSL certificate is now provided in the phar file and extracted when running Guzzle from a phar.
+* You can now send any EntityEnclosingRequest with POST fields or POST files and cURL will handle creating bodies
+* POST requests using a custom entity body are now treated exactly like PUT requests but with a custom cURL method. This
+  means that the redirect behavior of POST requests with custom bodies will not be the same as POST requests that use
+  POST fields or files (the latter is only used when emulating a form POST in the browser).
+* Lots of cleanup to CurlHandle::factory and RequestFactory::createRequest
+
+## 3.3.1 - 2013-03-10
+
+* Added the ability to create PHP streaming responses from HTTP requests
+* Bug fix: Running any filters when parsing response headers with service descriptions

+  response location visitors.
+* Bug fix: Removed the possibility of creating configuration files with circular dependencies
+* RequestFactory::create() now uses the key of a POST file when setting the POST file name
+* Added xmlAllowEmpty to serialize an XML body even if no XML specific parameters are set
+
+## 3.3.0 - 2013-03-03

+* Bug fix: Fixed bug in `Guzzle\Http\Message\Response` where wrapping quotes were stripped from `getEtag()`
+* BC: Removed `Guzzle\Http\Utils` class
+* BC: Setting a service description on a client will no longer modify the client's command factories.
+* BC: Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using
+  the 'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
+* BC: `Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getSteamType()` are no longer converted to
+  lowercase
+* Operation parameter objects are now lazy loaded internally
+* Added ErrorResponsePlugin that can throw errors for responses defined in service description operations' errorResponses
+* Added support for instantiating responseType=class responseClass classes. Classes must implement
+  `Guzzle\Service\Command\ResponseClassInterface`

+  additional properties also support locations and can be used to parse JSON responses where the outermost part of the
+  JSON is an array
+* Added support for nested renaming of JSON models (rename sentAs to name)
+* CachePlugin
+    * Added support for stale-if-error so that the CachePlugin can now serve stale content from the cache on error
+    * Debug headers can now added to cached response in the CachePlugin
+
+## 3.2.0 - 2013-02-14
+
+* CurlMulti is no longer reused globally. A new multi object is created per-client. This helps to isolate clients.
+* URLs with no path no longer contain a "/" by default
+* Guzzle\Http\QueryString does no longer manages the leading "?". This is now handled in Guzzle\Http\Url.
+* BadResponseException no longer includes the full request and response message

+* Various updates to classes to use ServiceDescriptionInterface type hints rather than ServiceDescription
+* Header values can now be normalized into distinct values when multiple headers are combined with a comma separated list
+* xmlEncoding can now be customized for the XML declaration of a XML service description operation
+* Guzzle\Http\QueryString now uses Guzzle\Http\QueryAggregator\QueryAggregatorInterface objects to add custom value
+  aggregation and no longer uses callbacks
+* The URL encoding implementation of Guzzle\Http\QueryString can now be customized
+* Bug fix: Filters were not always invoked for array service description parameters
+* Bug fix: Redirects now use a target response body rather than a temporary response body
+* Bug fix: The default exponential backoff BackoffPlugin was not giving when the request threshold was exceeded

+
+## 3.1.2 - 2013-01-27
+

+Guzzle, PHP HTTP client
+=======================
+
+[![Latest Version](https://img.shields.io/github/release/guzzle/guzzle.svg?style=flat-square)](https://github.com/guzzle/guzzle/releases)
+[![Build Status](https://img.shields.io/travis/guzzle/guzzle.svg?style=flat-square)](https://travis-ci.org/guzzle/guzzle)
+[![Total Downloads](https://img.shields.io/packagist/dt/guzzlehttp/guzzle.svg?style=flat-square)](https://packagist.org/packages/guzzlehttp/guzzle)
+
+Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
+trivial to integrate with web services.
+
+- Simple interface for building query strings, POST requests, streaming large
+  uploads, streaming large downloads, using HTTP cookies, uploading JSON data,
+  etc...
+- Can send both synchronous and asynchronous requests using the same interface.
+- Uses PSR-7 interfaces for requests, responses, and streams. This allows you
+  to utilize other PSR-7 compatible libraries with Guzzle.
+- Abstracts away the underlying HTTP transport, allowing you to write
+  environment and transport agnostic code; i.e., no hard dependency on cURL,
+  PHP streams, sockets, or non-blocking event loops.
+- Middleware system allows you to augment and compose client behavior.
+
+```php
+$client = new \GuzzleHttp\Client();
+$res = $client->request('GET', 'https://api.github.com/repos/guzzle/guzzle');
+echo $res->getStatusCode();
+// 200
+echo $res->getHeaderLine('content-type');
+// 'application/json; charset=utf8'
+echo $res->getBody();
+// '{"id": 1420053, "name": "guzzle", ...}'
+
+// Send an asynchronous request.
+$request = new \GuzzleHttp\Psr7\Request('GET', 'http://httpbin.org');
+$promise = $client->sendAsync($request)->then(function ($response) {
+    echo 'I completed! ' . $response->getBody();
+});
+$promise->wait();
+```
+
+## Help and docs

+- [Stack Overflow](http://stackoverflow.com/questions/tagged/guzzle)
+- [Gitter](https://gitter.im/guzzle/guzzle)
+
+
+## Installing Guzzle
+
+The recommended way to install Guzzle is through
+[Composer](http://getcomposer.org).
+
+```bash
+# Install Composer
+curl -sS https://getcomposer.org/installer | php
+```
+
+Next, run the Composer command to install the latest stable version of Guzzle:
+
+```bash
+php composer.phar require guzzlehttp/guzzle
+```
+
+After installing, you need to require Composer's autoloader:
+
+```php
+require 'vendor/autoload.php';
+```
+
+You can then later update Guzzle using composer:
+
+ ```bash
+composer.phar update
+ ```
+

+Guzzle Upgrade Guide
+====================
+
+5.0 to 6.0
+----------
+
+Guzzle now uses [PSR-7](http://www.php-fig.org/psr/psr-7/) for HTTP messages.
+Due to the fact that these messages are immutable, this prompted a refactoring
+of Guzzle to use a middleware based system rather than an event system. Any
+HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be
+updated to work with the new immutable PSR-7 request and response objects. Any
+event listeners or subscribers need to be updated to become middleware
+functions that wrap handlers (or are injected into a
+`GuzzleHttp\HandlerStack`).
+
+- Removed `GuzzleHttp\BatchResults`
+- Removed `GuzzleHttp\Collection`
+- Removed `GuzzleHttp\HasDataTrait`
+- Removed `GuzzleHttp\ToArrayInterface`
+- The `guzzlehttp/streams` dependency has been removed. Stream functionality
+  is now present in the `GuzzleHttp\Psr7` namespace provided by the
+  `guzzlehttp/psr7` package.
+- Guzzle no longer uses ReactPHP promises and now uses the
+  `guzzlehttp/promises` library. We use a custom promise library for three
+  significant reasons:
+  1. React promises (at the time of writing this) are recursive. Promise
+     chaining and promise resolution will eventually blow the stack. Guzzle
+     promises are not recursive as they use a sort of trampolining technique.
+     Note: there has been movement in the React project to modify promises to
+     no longer utilize recursion.
+  2. Guzzle needs to have the ability to synchronously block on a promise to
+     wait for a result. Guzzle promises allows this functionality (and does
+     not require the use of recursion).
+  3. Because we need to be able to wait on a result, doing so using React
+     promises requires wrapping react promises with RingPHP futures. This
+     overhead is no longer needed, reducing stack sizes, reducing complexity,
+     and improving performance.
+- `GuzzleHttp\Mimetypes` has been moved to a function in
+  `GuzzleHttp\Psr7\mimetype_from_extension` and
+  `GuzzleHttp\Psr7\mimetype_from_filename`.
+- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query
+  strings must now be passed into request objects as strings, or provided to
+  the `query` request option when creating requests with clients. The `query`
+  option uses PHP's `http_build_query` to convert an array to a string. If you
+  need a different serialization technique, you will need to pass the query
+  string in as a string. There are a couple helper functions that will make
+  working with query strings easier: `GuzzleHttp\Psr7\parse_query` and
+  `GuzzleHttp\Psr7\build_query`.
+- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware
+  system based on PSR-7, using RingPHP and it's middleware system as well adds
+  more complexity than the benefits it provides. All HTTP handlers that were
+  present in RingPHP have been modified to work directly with PSR-7 messages
+  and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces
+  complexity in Guzzle, removes a dependency, and improves performance. RingPHP
+  will be maintained for Guzzle 5 support, but will no longer be a part of
+  Guzzle 6.
+- As Guzzle now uses a middleware based systems the event system and RingPHP
+  integration has been removed. Note: while the event system has been removed,
+  it is possible to add your own type of event system that is powered by the
+  middleware system.
+  - Removed the `Event` namespace.
+  - Removed the `Subscriber` namespace.
+  - Removed `Transaction` class
+  - Removed `RequestFsm`
+  - Removed `RingBridge`
+  - `GuzzleHttp\Subscriber\Cookie` is now provided by
+    `GuzzleHttp\Middleware::cookies`
+  - `GuzzleHttp\Subscriber\HttpError` is now provided by
+    `GuzzleHttp\Middleware::httpError`
+  - `GuzzleHttp\Subscriber\History` is now provided by
+    `GuzzleHttp\Middleware::history`
+  - `GuzzleHttp\Subscriber\Mock` is now provided by
+    `GuzzleHttp\Handler\MockHandler`
+  - `GuzzleHttp\Subscriber\Prepare` is now provided by
+    `GuzzleHttp\PrepareBodyMiddleware`
+  - `GuzzleHttp\Subscriber\Redirect` is now provided by
+    `GuzzleHttp\RedirectMiddleware`
+- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in
+  `GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone.
+- Static functions in `GuzzleHttp\Utils` have been moved to namespaced
+  functions under the `GuzzleHttp` namespace. This requires either a Composer
+  based autoloader or you to include functions.php.
+- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to
+  `GuzzleHttp\ClientInterface::getConfig`.
+- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed.
+- The `json` and `xml` methods of response objects has been removed. With the
+  migration to strictly adhering to PSR-7 as the interface for Guzzle messages,
+  adding methods to message interfaces would actually require Guzzle messages
+  to extend from PSR-7 messages rather then work with them directly.
+
+## Migrating to middleware
+
+The change to PSR-7 unfortunately required significant refactoring to Guzzle
+due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event
+system from plugins. The event system relied on mutability of HTTP messages and
+side effects in order to work. With immutable messages, you have to change your
+workflow to become more about either returning a value (e.g., functional
+middlewares) or setting a value on an object. Guzzle v6 has chosen the
+functional middleware approach.
+
+Instead of using the event system to listen for things like the `before` event,
+you now create a stack based middleware function that intercepts a request on
+the way in and the promise of the response on the way out. This is a much
+simpler and more predictable approach than the event system and works nicely
+with PSR-7 middleware. Due to the use of promises, the middleware system is
+also asynchronous.
+
+v5:
+
+```php
+use GuzzleHttp\Event\BeforeEvent;
+$client = new GuzzleHttp\Client();
+// Get the emitter and listen to the before event.
+$client->getEmitter()->on('before', function (BeforeEvent $e) {
+    // Guzzle v5 events relied on mutation
+    $e->getRequest()->setHeader('X-Foo', 'Bar');
+});
+```
+
+v6:
+
+In v6, you can modify the request before it is sent using the `mapRequest`
+middleware. The idiomatic way in v6 to modify the request/response lifecycle is
+to setup a handler middleware stack up front and inject the handler into a
+client.
+
+```php
+use GuzzleHttp\Middleware;
+// Create a handler stack that has all of the default middlewares attached
+$handler = GuzzleHttp\HandlerStack::create();
+// Push the handler onto the handler stack
+$handler->push(Middleware::mapRequest(function (RequestInterface $request) {
+    // Notice that we have to return a request object
+    return $request->withHeader('X-Foo', 'Bar');
+}));
+// Inject the handler into the client
+$client = new GuzzleHttp\Client(['handler' => $handler]);
+```
+
+## POST Requests
+
+This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params)
+and `multipart` request options. `form_params` is an associative array of
+strings or array of strings and is used to serialize an
+`application/x-www-form-urlencoded` POST request. The
+[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart)
+option is now used to send a multipart/form-data POST request.
+
+`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add
+POST files to a multipart/form-data request.
+
+The `body` option no longer accepts an array to send POST requests. Please use
+`multipart` or `form_params` instead.
+
+The `base_url` option has been renamed to `base_uri`.
+
+4.x to 5.0
+----------
+
+## Rewritten Adapter Layer
+
+Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send
+HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor
+is still supported, but it has now been renamed to `handler`. Instead of
+passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP
+`callable` that follows the RingPHP specification.
+
+## Removed Fluent Interfaces
+
+[Fluent interfaces were removed](http://ocramius.github.io/blog/fluent-interfaces-are-evil)
+from the following classes:
+
+- `GuzzleHttp\Collection`
+- `GuzzleHttp\Url`
+- `GuzzleHttp\Query`
+- `GuzzleHttp\Post\PostBody`
+- `GuzzleHttp\Cookie\SetCookie`
+
+## Removed functions.php
+
+Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following
+functions can be used as replacements.
+
+- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode`
+- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath`
+- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path`
+- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however,
+  deprecated in favor of using `GuzzleHttp\Pool::batch()`.
+
+The "procedural" global client has been removed with no replacement (e.g.,
+`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client`
+object as a replacement.
+
+## `throwImmediately` has been removed
+
+The concept of "throwImmediately" has been removed from exceptions and error
+events. This control mechanism was used to stop a transfer of concurrent
+requests from completing. This can now be handled by throwing the exception or
+by cancelling a pool of requests or each outstanding future request
+individually.
+
+## headers event has been removed
+
+Removed the "headers" event. This event was only useful for changing the
+body a response once the headers of the response were known. You can implement
+a similar behavior in a number of ways. One example might be to use a
+FnStream that has access to the transaction being sent. For example, when the
+first byte is written, you could check if the response headers match your
+expectations, and if so, change the actual stream body that is being
+written to.
+
+## Updates to HTTP Messages
+
+Removed the `asArray` parameter from
+`GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
+value as an array, then use the newly added `getHeaderAsArray()` method of
+`MessageInterface`. This change makes the Guzzle interfaces compatible with
+the PSR-7 interfaces.
+
+3.x to 4.0
+----------
+
+## Overarching changes:
+
+- Now requires PHP 5.4 or greater.
+- No longer requires cURL to send requests.
+- Guzzle no longer wraps every exception it throws. Only exceptions that are
+  recoverable are now wrapped by Guzzle.
+- Various namespaces have been removed or renamed.
+- No longer requiring the Symfony EventDispatcher. A custom event dispatcher
+  based on the Symfony EventDispatcher is
+  now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant
+  speed and functionality improvements).
+
+Changes per Guzzle 3.x namespace are described below.
+
+## Batch
+
+The `Guzzle\Batch` namespace has been removed. This is best left to
+third-parties to implement on top of Guzzle's core HTTP library.
+
+## Cache
+
+The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement
+has been implemented yet, but hoping to utilize a PSR cache interface).
+
+## Common
+
+- Removed all of the wrapped exceptions. It's better to use the standard PHP
+  library for unrecoverable exceptions.
+- `FromConfigInterface` has been removed.
+- `Guzzle\Common\Version` has been removed. The VERSION constant can be found
+  at `GuzzleHttp\ClientInterface::VERSION`.
+
+### Collection
+
+- `getAll` has been removed. Use `toArray` to convert a collection to an array.
+- `inject` has been removed.
+- `keySearch` has been removed.
+- `getPath` no longer supports wildcard expressions. Use something better like
+  JMESPath for this.
+- `setPath` now supports appending to an existing array via the `[]` notation.
+
+### Events
+
+Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses
+`GuzzleHttp\Event\Emitter`.
+
+- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by
+  `GuzzleHttp\Event\EmitterInterface`.
+- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by
+  `GuzzleHttp\Event\Emitter`.
+- `Symfony\Component\EventDispatcher\Event` is replaced by
+  `GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in
+  `GuzzleHttp\Event\EventInterface`.
+- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and
+  `HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the
+  event emitter of a request, client, etc. now uses the `getEmitter` method
+  rather than the `getDispatcher` method.
+
+#### Emitter
+
+- Use the `once()` method to add a listener that automatically removes itself
+  the first time it is invoked.
+- Use the `listeners()` method to retrieve a list of event listeners rather than
+  the `getListeners()` method.
+- Use `emit()` instead of `dispatch()` to emit an event from an emitter.
+- Use `attach()` instead of `addSubscriber()` and `detach()` instead of
+  `removeSubscriber()`.
+
+```php
+$mock = new Mock();
+// 3.x
+$request->getEventDispatcher()->addSubscriber($mock);
+$request->getEventDispatcher()->removeSubscriber($mock);
+// 4.x
+$request->getEmitter()->attach($mock);
+$request->getEmitter()->detach($mock);
+```
+
+Use the `on()` method to add a listener rather than the `addListener()` method.
+
+```php
+// 3.x
+$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } );
+// 4.x
+$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } );
+```
+
+## Http
+
+### General changes
+
+- The cacert.pem certificate has been moved to `src/cacert.pem`.
+- Added the concept of adapters that are used to transfer requests over the
+  wire.
+- Simplified the event system.
+- Sending requests in parallel is still possible, but batching is no longer a
+  concept of the HTTP layer. Instead, you must use the `complete` and `error`
+  events to asynchronously manage parallel request transfers.
+- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`.
+- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`.
+- QueryAggregators have been rewritten so that they are simply callable
+  functions.
+- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in
+  `functions.php` for an easy to use static client instance.
+- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from
+  `GuzzleHttp\Exception\TransferException`.
+
+### Client
+
+Calling methods like `get()`, `post()`, `head()`, etc. no longer create and
+return a request, but rather creates a request, sends the request, and returns
+the response.
+
+```php
+// 3.0
+$request = $client->get('/');
+$response = $request->send();
+
+// 4.0
+$response = $client->get('/');
+
+// or, to mirror the previous behavior
+$request = $client->createRequest('GET', '/');
+$response = $client->send($request);
+```
+
+`GuzzleHttp\ClientInterface` has changed.
+
+- The `send` method no longer accepts more than one request. Use `sendAll` to
+  send multiple requests in parallel.
+- `setUserAgent()` has been removed. Use a default request option instead. You
+  could, for example, do something like:
+  `$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`.
+- `setSslVerification()` has been removed. Use default request options instead,
+  like `$client->setConfig('defaults/verify', true)`.
+
+`GuzzleHttp\Client` has changed.
+
+- The constructor now accepts only an associative array. You can include a
+  `base_url` string or array to use a URI template as the base URL of a client.
+  You can also specify a `defaults` key that is an associative array of default
+  request options. You can pass an `adapter` to use a custom adapter,
+  `batch_adapter` to use a custom adapter for sending requests in parallel, or
+  a `message_factory` to change the factory used to create HTTP requests and
+  responses.
+- The client no longer emits a `client.create_request` event.
+- Creating requests with a client no longer automatically utilize a URI
+  template. You must pass an array into a creational method (e.g.,
+  `createRequest`, `get`, `put`, etc.) in order to expand a URI template.
+
+### Messages
+
+Messages no longer have references to their counterparts (i.e., a request no
+longer has a reference to it's response, and a response no loger has a
+reference to its request). This association is now managed through a
+`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to
+these transaction objects using request events that are emitted over the
+lifecycle of a request.
+
+#### Requests with a body
+
+- `GuzzleHttp\Message\EntityEnclosingRequest` and
+  `GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The
+  separation between requests that contain a body and requests that do not
+  contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface`
+  handles both use cases.
+- Any method that previously accepts a `GuzzleHttp\Response` object now accept a
+  `GuzzleHttp\Message\ResponseInterface`.
+- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to
+  `GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create
+  both requests and responses and is implemented in
+  `GuzzleHttp\Message\MessageFactory`.
+- POST field and file methods have been removed from the request object. You
+  must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface`
+  to control the format of a POST body. Requests that are created using a
+  standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use
+  a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if
+  the method is POST and no body is provided.
+
+```php
+$request = $client->createRequest('POST', '/');
+$request->getBody()->setField('foo', 'bar');
+$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r')));
+```
+
+#### Headers
+
+- `GuzzleHttp\Message\Header` has been removed. Header values are now simply
+  represented by an array of values or as a string. Header values are returned
+  as a string by default when retrieving a header value from a message. You can
+  pass an optional argument of `true` to retrieve a header value as an array
+  of strings instead of a single concatenated string.
+- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to
+  `GuzzleHttp\Post`. This interface has been simplified and now allows the
+  addition of arbitrary headers.
+- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most
+  of the custom headers are now handled separately in specific
+  subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has
+  been updated to properly handle headers that contain parameters (like the
+  `Link` header).
+
+#### Responses
+
+- `GuzzleHttp\Message\Response::getInfo()` and
+  `GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event
+  system to retrieve this type of information.
+- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed.
+- `GuzzleHttp\Message\Response::getMessage()` has been removed.
+- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific
+  methods have moved to the CacheSubscriber.
+- Header specific helper functions like `getContentMd5()` have been removed.
+  Just use `getHeader('Content-MD5')` instead.
+- `GuzzleHttp\Message\Response::setRequest()` and
+  `GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event
+  system to work with request and response objects as a transaction.
+- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the
+  Redirect subscriber instead.
+- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have
+  been removed. Use `getStatusCode()` instead.
+
+#### Streaming responses
+
+Streaming requests can now be created by a client directly, returning a
+`GuzzleHttp\Message\ResponseInterface` object that contains a body stream
+referencing an open PHP HTTP stream.
+
+```php
+// 3.0
+use Guzzle\Stream\PhpStreamRequestFactory;
+$request = $client->get('/');
+$factory = new PhpStreamRequestFactory();
+$stream = $factory->fromRequest($request);
+$data = $stream->read(1024);
+
+// 4.0
+$response = $client->get('/', ['stream' => true]);
+// Read some data off of the stream in the response body
+$data = $response->getBody()->read(1024);
+```
+
+#### Redirects
+
+The `configureRedirects()` method has been removed in favor of a
+`allow_redirects` request option.
+
+```php
+// Standard redirects with a default of a max of 5 redirects
+$request = $client->createRequest('GET', '/', ['allow_redirects' => true]);
+
+// Strict redirects with a custom number of redirects
+$request = $client->createRequest('GET', '/', [
+    'allow_redirects' => ['max' => 5, 'strict' => true]
+]);
+```
+
+#### EntityBody
+
+EntityBody interfaces and classes have been removed or moved to
+`GuzzleHttp\Stream`. All classes and interfaces that once required
+`GuzzleHttp\EntityBodyInterface` now require
+`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no
+longer uses `GuzzleHttp\EntityBody::factory` but now uses
+`GuzzleHttp\Stream\Stream::factory` or even better:
+`GuzzleHttp\Stream\create()`.
+
+- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface`
+- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream`
+- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream`
+- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream`
+- `Guzzle\Http\IoEmittyinEntityBody` has been removed.
+
+#### Request lifecycle events
+
+Requests previously submitted a large number of requests. The number of events
+emitted over the lifecycle of a request has been significantly reduced to make
+it easier to understand how to extend the behavior of a request. All events
+emitted during the lifecycle of a request now emit a custom
+`GuzzleHttp\Event\EventInterface` object that contains context providing
+methods and a way in which to modify the transaction at that specific point in
+time (e.g., intercept the request and set a response on the transaction).
+
+- `request.before_send` has been renamed to `before` and now emits a
+  `GuzzleHttp\Event\BeforeEvent`
+- `request.complete` has been renamed to `complete` and now emits a
+  `GuzzleHttp\Event\CompleteEvent`.
+- `request.sent` has been removed. Use `complete`.
+- `request.success` has been removed. Use `complete`.
+- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`.
+- `request.exception` has been removed. Use `error`.
+- `request.receive.status_line` has been removed.
+- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to
+  maintain a status update.
+- `curl.callback.write` has been removed. Use a custom `StreamInterface` to
+  intercept writes.
+- `curl.callback.read` has been removed. Use a custom `StreamInterface` to
+  intercept reads.
+
+`headers` is a new event that is emitted after the response headers of a
+request have been received before the body of the response is downloaded. This
+event emits a `GuzzleHttp\Event\HeadersEvent`.
+
+You can intercept a request and inject a response using the `intercept()` event
+of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and
+`GuzzleHttp\Event\ErrorEvent` event.
+
+See: http://docs.guzzlephp.org/en/latest/events.html
+
+## Inflection
+
+The `Guzzle\Inflection` namespace has been removed. This is not a core concern
+of Guzzle.
+
+## Iterator
+
+The `Guzzle\Iterator` namespace has been removed.
+
+- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and
+  `Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of
+  Guzzle itself.
+- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent
+  class is shipped with PHP 5.4.
+- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because
+  it's easier to just wrap an iterator in a generator that maps values.
+
+For a replacement of these iterators, see https://github.com/nikic/iter
+
+## Log
+
+The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The
+`Guzzle\Log` namespace has been removed. Guzzle now relies on
+`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been
+moved to `GuzzleHttp\Subscriber\Log\Formatter`.
+
+## Parser
+
+The `Guzzle\Parser` namespace has been removed. This was previously used to
+make it possible to plug in custom parsers for cookies, messages, URI
+templates, and URLs; however, this level of complexity is not needed in Guzzle
+so it has been removed.
+
+- Cookie: Cookie parsing logic has been moved to
+  `GuzzleHttp\Cookie\SetCookie::fromString`.
+- Message: Message parsing logic for both requests and responses has been moved
+  to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only
+  used in debugging or deserializing messages, so it doesn't make sense for
+  Guzzle as a library to add this level of complexity to parsing messages.
+- UriTemplate: URI template parsing has been moved to
+  `GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL
+  URI template library if it is installed.
+- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously
+  it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary,
+  then developers are free to subclass `GuzzleHttp\Url`.
+
+## Plugin
+
+The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`.
+Several plugins are shipping with the core Guzzle library under this namespace.
+
+- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar
+  code has moved to `GuzzleHttp\Cookie`.
+- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin.
+- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is
+  received.
+- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin.
+- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before
+  sending. This subscriber is attached to all requests by default.
+- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin.
+
+The following plugins have been removed (third-parties are free to re-implement
+these if needed):
+
+- `GuzzleHttp\Plugin\Async` has been removed.
+- `GuzzleHttp\Plugin\CurlAuth` has been removed.
+- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This
+  functionality should instead be implemented with event listeners that occur
+  after normal response parsing occurs in the guzzle/command package.
+
+The following plugins are not part of the core Guzzle package, but are provided
+in separate repositories:
+
+- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler
+  to build custom retry policies using simple functions rather than various
+  chained classes. See: https://github.com/guzzle/retry-subscriber
+- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to
+  https://github.com/guzzle/cache-subscriber
+- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to
+  https://github.com/guzzle/log-subscriber
+- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to
+  https://github.com/guzzle/message-integrity-subscriber
+- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to
+  `GuzzleHttp\Subscriber\MockSubscriber`.
+- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to
+  https://github.com/guzzle/oauth-subscriber
+
+## Service
+
+The service description layer of Guzzle has moved into two separate packages:
+
+- http://github.com/guzzle/command Provides a high level abstraction over web
+  services by representing web service operations using commands.
+- http://github.com/guzzle/guzzle-services Provides an implementation of
+  guzzle/command that provides request serialization and response parsing using
+  Guzzle service descriptions.
+
+## Stream
+
+Stream have moved to a separate package available at
+https://github.com/guzzle/streams.
+
+`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take
+on the responsibilities of `Guzzle\Http\EntityBody` and
+`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number
+of methods implemented by the `StreamInterface` has been drastically reduced to
+allow developers to more easily extend and decorate stream behavior.
+
+## Removed methods from StreamInterface
+
+- `getStream` and `setStream` have been removed to better encapsulate streams.
+- `getMetadata` and `setMetadata` have been removed in favor of
+  `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been
+  removed. This data is accessible when
+  using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`.
+- `rewind` has been removed. Use `seek(0)` for a similar behavior.
+
+## Renamed methods
+
+- `detachStream` has been renamed to `detach`.
+- `feof` has been renamed to `eof`.
+- `ftell` has been renamed to `tell`.
+- `readLine` has moved from an instance method to a static class method of
+  `GuzzleHttp\Stream\Stream`.
+
+## Metadata streams
+
+`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams
+that contain additional metadata accessible via `getMetadata()`.
+`GuzzleHttp\Stream\StreamInterface::getMetadata` and
+`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed.
+
+## StreamRequestFactory
+
+The entire concept of the StreamRequestFactory has been removed. The way this
+was used in Guzzle 3 broke the actual interface of sending streaming requests
+(instead of getting back a Response, you got a StreamInterface). Streaming
+PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`.
+
+3.6 to 3.7
+----------
+
+### Deprecations
+
+- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.:
+
+```php
+\Guzzle\Common\Version::$emitWarnings = true;
+```
+
+The following APIs and options have been marked as deprecated:
+
+- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$request->getResponseBody()->isRepeatable()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
+- Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
+- Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
+- Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
+- Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
+- Marked `Guzzle\Common\Collection::inject()` as deprecated.
+- Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use
+  `$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or
+  `$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));`
+
+3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational
+request methods. When paired with a client's configuration settings, these options allow you to specify default settings
+for various aspects of a request. Because these options make other previous configuration options redundant, several
+configuration options and methods of a client and AbstractCommand have been deprecated.
+
+- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`.
+- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`.
+- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')`
+- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0
+
+        $command = $client->getCommand('foo', array(
+            'command.headers' => array('Test' => '123'),
+            'command.response_body' => '/path/to/file'
+        ));
+
+        // Should be changed to:
+
+        $command = $client->getCommand('foo', array(
+            'command.request_options' => array(
+                'headers' => array('Test' => '123'),
+                'save_as' => '/path/to/file'
+            )
+        ));
+
+### Interface changes
+
+Additions and changes (you will need to update any implementations or subclasses you may have created):
+
+- Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
+  createRequest, head, delete, put, patch, post, options, prepareRequest
+- Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
+- Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
+- Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
+  `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
+  resource, string, or EntityBody into the $options parameter to specify the download location of the response.
+- Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
+  default `array()`
+- Added `Guzzle\Stream\StreamInterface::isRepeatable`
+- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
+
+The following methods were removed from interfaces. All of these methods are still available in the concrete classes
+that implement them, but you should update your code to use alternative methods:
+
+- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
+  `$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
+  `$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or
+  `$client->setDefaultOption('headers/{header_name}', 'value')`. or
+  `$client->setDefaultOption('headers', array('header_name' => 'value'))`.
+- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`.
+- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail.
+- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail.
+- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin.
+- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin.
+
+### Cache plugin breaking changes
+
+- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
+  CacheStorageInterface. These two objects and interface will be removed in a future version.
+- Always setting X-cache headers on cached responses
+- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
+- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
+  $request, Response $response);`
+- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
+- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
+- Added `CacheStorageInterface::purge($url)`
+- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
+  $plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
+  CanCacheStrategyInterface $canCache = null)`
+- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
+
+3.5 to 3.6
+----------
+
+* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
+* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
+* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
+  For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader().
+  Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request.
+* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
+  HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
+  CacheControl header implementation.
+* Moved getLinks() from Response to just be used on a Link header object.
+
+If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the
+HeaderInterface (e.g. toArray(), getAll(), etc.).
+
+### Interface changes
+
+* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
+* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
+* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
+  Guzzle\Http\Curl\RequestMediator
+* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
+* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
+* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
+
+### Removed deprecated functions
+
+* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
+* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
+
+### Deprecations
+
+* The ability to case-insensitively search for header values
+* Guzzle\Http\Message\Header::hasExactHeader
+* Guzzle\Http\Message\Header::raw. Use getAll()
+* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
+  instead.
+
+### Other changes
+
+* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
+* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
+  directly via interfaces
+* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
+  but are a no-op until removed.
+* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
+  `Guzzle\Service\Command\ArrayCommandInterface`.
+* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
+  on a request while the request is still being transferred
+* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
+
+3.3 to 3.4
+----------
+
+Base URLs of a client now follow the rules of http://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs.
+
+3.2 to 3.3
+----------
+
+### Response::getEtag() quote stripping removed
+
+`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header
+
+### Removed `Guzzle\Http\Utils`
+
+The `Guzzle\Http\Utils` class was removed. This class was only used for testing.
+
+### Stream wrapper and type
+
+`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getStreamType()` are no longer converted to lowercase.
+
+### curl.emit_io became emit_io
+
+Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the
+'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
+
+3.1 to 3.2
+----------
+
+### CurlMulti is no longer reused globally
+
+Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added
+to a single client can pollute requests dispatched from other clients.
+
+If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the
+ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is
+created.
+
+```php
+$multi = new Guzzle\Http\Curl\CurlMulti();
+$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json');
+$builder->addListener('service_builder.create_client', function ($event) use ($multi) {
+    $event['client']->setCurlMulti($multi);
+}
+});
+```
+
+### No default path
+
+URLs no longer have a default path value of '/' if no path was specified.
+
+Before:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com/
+```
+
+After:
+
+```php
+$request = $client->get('http://www.foo.com');
+echo $request->getUrl();
+// >> http://www.foo.com
+```
+
+### Less verbose BadResponseException
+
+The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and
+response information. You can, however, get access to the request and response object by calling `getRequest()` or
+`getResponse()` on the exception object.
+
+### Query parameter aggregation
+
+Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a
+setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is
+responsible for handling the aggregation of multi-valued query string variables into a flattened hash.
+
+2.8 to 3.x
+----------
+
+### Guzzle\Service\Inspector
+
+Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig`
+
+**Before**
+
+```php
+use Guzzle\Service\Inspector;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Inspector::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```
+
+**After**
+
+```php
+use Guzzle\Common\Collection;
+
+class YourClient extends \Guzzle\Service\Client
+{
+    public static function factory($config = array())
+    {
+        $default = array();
+        $required = array('base_url', 'username', 'api_key');
+        $config = Collection::fromConfig($config, $default, $required);
+
+        $client = new self(
+            $config->get('base_url'),
+            $config->get('username'),
+            $config->get('api_key')
+        );
+        $client->setConfig($config);
+
+        $client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
+
+        return $client;
+    }
+```

+```
+
+### Guzzle\Http\Plugin\CurlAuthPlugin
+
+Now `Guzzle\Plugin\CurlAuth\CurlAuthPlugin`.
+
+### Guzzle\Http\Plugin\ExponentialBackoffPlugin
+
+Now `Guzzle\Plugin\Backoff\BackoffPlugin`, and other changes.
+
+**Before**
+
+```php
+use Guzzle\Http\Plugin\ExponentialBackoffPlugin;
+
+$backoffPlugin = new ExponentialBackoffPlugin($maxRetries, array_merge(
+        ExponentialBackoffPlugin::getDefaultFailureCodes(), array(429)
+    ));
+
+$client->addSubscriber($backoffPlugin);
+```
+
+**After**
+
+```php
+use Guzzle\Plugin\Backoff\BackoffPlugin;
+use Guzzle\Plugin\Backoff\HttpBackoffStrategy;
+
+// Use convenient factory method instead -- see implementation for ideas of what
+// you can do with chaining backoff strategies
+$backoffPlugin = BackoffPlugin::getExponentialBackoff($maxRetries, array_merge(
+        HttpBackoffStrategy::getDefaultFailureCodes(), array(429)
+    ));
+$client->addSubscriber($backoffPlugin);
+```
+
+### Known Issues
+
+#### [BUG] Accept-Encoding header behavior changed unintentionally.
+
+(See #217) (Fixed in 09daeb8c666fb44499a0646d655a8ae36456575e)
+
+In version 2.8 setting the `Accept-Encoding` header would set the CURLOPT_ENCODING option, which permitted cURL to
+properly handle gzip/deflate compressed responses from the server. In versions affected by this bug this does not happen.
+See issue #217 for a workaround, or use a version containing the fix.

+# Features
+
+- [Promises/A+](https://promisesaplus.com/) implementation.
+- Promise resolution and chaining is handled iteratively, allowing for
+  "infinite" promise chaining.
+- Promises have a synchronous `wait` method.
+- Promises can be cancelled.
+- Works with any object that has a `then` function.
+- C# style async/await coroutine promises using
+  `GuzzleHttp\Promise\coroutine()`.
+
+
+# Quick start
+
+A *promise* represents the eventual result of an asynchronous operation. The
+primary way of interacting with a promise is through its `then` method, which
+registers callbacks to receive either a promise's eventual value or the reason
+why the promise cannot be fulfilled.
+
+
+## Callbacks
+
+Callbacks are registered with the `then` method by providing an optional 
+`$onFulfilled` followed by an optional `$onRejected` function.
+
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(
+    // $onFulfilled
+    function ($value) {
+        echo 'The promise was fulfilled.';
+    },
+    // $onRejected
+    function ($reason) {
+        echo 'The promise was rejected.';
+    }
+);
+```
+
+*Resolving* a promise means that you either fulfill a promise with a *value* or
+reject a promise with a *reason*. Resolving a promises triggers callbacks
+registered with the promises's `then` method. These callbacks are triggered
+only once and in the order in which they were added.
+
+
+## Resolving a promise
+
+Promises are fulfilled using the `resolve($value)` method. Resolving a promise
+with any value other than a `GuzzleHttp\Promise\RejectedPromise` will trigger
+all of the onFulfilled callbacks (resolving a promise with a rejected promise
+will reject the promise and trigger the `$onRejected` callbacks).
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise
+    ->then(function ($value) {
+        // Return a value and don't break the chain
+        return "Hello, " . $value;
+    })
+    // This then is executed after the first then and receives the value
+    // returned from the first then.
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Resolving the promise triggers the $onFulfilled callbacks and outputs
+// "Hello, reader".
+$promise->resolve('reader.');
+```
+
+
+## Promise forwarding
+
+Promises can be chained one after the other. Each then in the chain is a new
+promise. The return value of a promise is what's forwarded to the next
+promise in the chain. Returning a promise in a `then` callback will cause the
+subsequent promises in the chain to only be fulfilled when the returned promise
+has been fulfilled. The next promise in the chain will be invoked with the
+resolved value of the promise.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$nextPromise = new Promise();
+
+$promise
+    ->then(function ($value) use ($nextPromise) {
+        echo $value;
+        return $nextPromise;
+    })
+    ->then(function ($value) {
+        echo $value;
+    });
+
+// Triggers the first callback and outputs "A"
+$promise->resolve('A');
+// Triggers the second callback and outputs "B"
+$nextPromise->resolve('B');
+```
+
+## Promise rejection
+
+When a promise is rejected, the `$onRejected` callbacks are invoked with the
+rejection reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+
+$promise->reject('Error!');
+// Outputs "Error!"
+```
+
+## Rejection forwarding
+
+If an exception is thrown in an `$onRejected` callback, subsequent
+`$onRejected` callbacks are invoked with the thrown exception as the reason.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    throw new \Exception($reason);
+})->then(null, function ($reason) {
+    assert($reason->getMessage() === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+You can also forward a rejection down the promise chain by returning a
+`GuzzleHttp\Promise\RejectedPromise` in either an `$onFulfilled` or
+`$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise->then(null, function ($reason) {
+    return new RejectedPromise($reason);
+})->then(null, function ($reason) {
+    assert($reason === 'Error!');
+});
+
+$promise->reject('Error!');
+```
+
+If an exception is not thrown in a `$onRejected` callback and the callback
+does not return a rejected promise, downstream `$onFulfilled` callbacks are
+invoked using the value returned from the `$onRejected` callback.
+
+```php
+use GuzzleHttp\Promise\Promise;
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new Promise();
+$promise
+    ->then(null, function ($reason) {
+        return "It's ok";
+    })
+    ->then(function ($value) {
+        assert($value === "It's ok");
+    });
+
+$promise->reject('Error!');
+```
+
+# Synchronous wait
+
+You can synchronously force promises to complete using a promise's `wait`
+method. When creating a promise, you can provide a wait function that is used
+to synchronously force a promise to complete. When a wait function is invoked
+it is expected to deliver a value to the promise or reject the promise. If the
+wait function does not deliver a value, then an exception is thrown. The wait
+function provided to a promise constructor is invoked when the `wait` function
+of the promise is called.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    $promise->resolve('foo');
+});
+
+// Calling wait will return the value of the promise.
+echo $promise->wait(); // outputs "foo"
+```
+
+If an exception is encountered while invoking the wait function of a promise,
+the promise is rejected with the exception and the exception is thrown.
+
+```php
+$promise = new Promise(function () use (&$promise) {
+    throw new \Exception('foo');
+});
+
+$promise->wait(); // throws the exception.
+```
+
+Calling `wait` on a promise that has been fulfilled will not trigger the wait
+function. It will simply return the previously resolved value.
+
+```php
+$promise = new Promise(function () { die('this is not called!'); });
+$promise->resolve('foo');
+echo $promise->wait(); // outputs "foo"
+```
+
+Calling `wait` on a promise that has been rejected will throw an exception. If
+the rejection reason is an instance of `\Exception` the reason is thrown.
+Otherwise, a `GuzzleHttp\Promise\RejectionException` is thrown and the reason
+can be obtained by calling the `getReason` method of the exception.
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+$promise->wait();
+```
+
+> PHP Fatal error:  Uncaught exception 'GuzzleHttp\Promise\RejectionException' with message 'The promise was rejected with value: foo'
+
+
+## Unwrapping a promise
+
+When synchronously waiting on a promise, you are joining the state of the
+promise into the current state of execution (i.e., return the value of the
+promise if it was fulfilled or throw an exception if it was rejected). This is
+called "unwrapping" the promise. Waiting on a promise will by default unwrap
+the promise state.
+
+You can force a promise to resolve and *not* unwrap the state of the promise
+by passing `false` to the first argument of the `wait` function:
+
+```php
+$promise = new Promise();
+$promise->reject('foo');
+// This will not throw an exception. It simply ensures the promise has
+// been resolved.
+$promise->wait(false);
+```
+
+When unwrapping a promise, the resolved value of the promise will be waited
+upon until the unwrapped value is not a promise. This means that if you resolve
+promise A with a promise B and unwrap promise A, the value returned by the
+wait function will be the value delivered to promise B.
+
+**Note**: when you do not unwrap the promise, no value is returned.
+
+
+# Cancellation
+
+You can cancel a promise that has not yet been fulfilled using the `cancel()`
+method of a promise. When creating a promise you can provide an optional
+cancel function that when invoked cancels the action of computing a resolution
+of the promise.
+
+
+# API
+
+
+## Promise
+
+When creating a promise object, you can provide an optional `$waitFn` and
+`$cancelFn`. `$waitFn` is a function that is invoked with no arguments and is
+expected to resolve the promise. `$cancelFn` is a function with no arguments
+that is expected to cancel the computation of a promise. It is invoked when the
+`cancel()` method of a promise is called.
+
+```php
+use GuzzleHttp\Promise\Promise;
+
+$promise = new Promise(
+    function () use (&$promise) {
+        $promise->resolve('waited');
+    },
+    function () {
+        // do something that will cancel the promise computation (e.g., close
+        // a socket, cancel a database query, etc...)
+    }
+);
+
+assert('waited' === $promise->wait());
+```
+
+A promise has the following methods:
+
+- `then(callable $onFulfilled, callable $onRejected) : PromiseInterface`
+  
+  Appends fulfillment and rejection handlers to the promise, and returns a new promise resolving to the return value of the called handler.
+
+- `otherwise(callable $onRejected) : PromiseInterface`
+  
+  Appends a rejection handler callback to the promise, and returns a new promise resolving to the return value of the callback if it is called, or to its original fulfillment value if the promise is instead fulfilled.
+
+- `wait($unwrap = true) : mixed`
+
+  Synchronously waits on the promise to complete.
+  
+  `$unwrap` controls whether or not the value of the promise is returned for a
+  fulfilled promise or if an exception is thrown if the promise is rejected.
+  This is set to `true` by default.
+
+- `cancel()`
+
+  Attempts to cancel the promise if possible. The promise being cancelled and
+  the parent most ancestor that has not yet been resolved will also be
+  cancelled. Any promises waiting on the cancelled promise to resolve will also
+  be cancelled.
+
+- `getState() : string`
+
+  Returns the state of the promise. One of `pending`, `fulfilled`, or
+  `rejected`.
+
+- `resolve($value)`
+
+  Fulfills the promise with the given `$value`.
+
+- `reject($reason)`
+
+  Rejects the promise with the given `$reason`.
+
+
+## FulfilledPromise
+
+A fulfilled promise can be created to represent a promise that has been
+fulfilled.
+
+```php
+use GuzzleHttp\Promise\FulfilledPromise;
+
+$promise = new FulfilledPromise('value');
+
+// Fulfilled callbacks are immediately invoked.
+$promise->then(function ($value) {
+    echo $value;
+});
+```
+
+
+## RejectedPromise
+
+A rejected promise can be created to represent a promise that has been
+rejected.
+
+```php
+use GuzzleHttp\Promise\RejectedPromise;
+
+$promise = new RejectedPromise('Error');
+
+// Rejected callbacks are immediately invoked.
+$promise->then(null, function ($reason) {
+    echo $reason;
+});
+```
+
+
+# Promise interop
+
+This library works with foreign promises that have a `then` method. This means
+you can use Guzzle promises with [React promises](https://github.com/reactphp/promise)
+for example. When a foreign promise is returned inside of a then method
+callback, promise resolution will occur recursively.
+
+```php
+// Create a React promise
+$deferred = new React\Promise\Deferred();
+$reactPromise = $deferred->promise();
+
+// Create a Guzzle promise that is fulfilled with a React promise.
+$guzzlePromise = new \GuzzleHttp\Promise\Promise();
+$guzzlePromise->then(function ($value) use ($reactPromise) {
+    // Do something something with the value...
+    // Return the React promise
+    return $reactPromise;
+});
+```
+
+Please note that wait and cancel chaining is no longer possible when forwarding
+a foreign promise. You will need to wrap a third-party promise with a Guzzle
+promise in order to utilize wait and cancel functions with foreign promises.
+
+
+## Event Loop Integration
+
+In order to keep the stack size constant, Guzzle promises are resolved
+asynchronously using a task queue. When waiting on promises synchronously, the
+task queue will be automatically run to ensure that the blocking promise and
+any forwarded promises are resolved. When using promises asynchronously in an
+event loop, you will need to run the task queue on each tick of the loop. If
+you do not run the task queue, then promises will not be resolved.
+
+You can run the task queue using the `run()` method of the global task queue
+instance.
+
+```php
+// Get the global task queue
+$queue = \GuzzleHttp\Promise\queue();
+$queue->run();
+```
+
+For example, you could use Guzzle promises with React using a periodic timer:
+
+```php
+$loop = React\EventLoop\Factory::create();
+$loop->addPeriodicTimer(0, [$queue, 'run']);
+```
+
+*TODO*: Perhaps adding a `futureTick()` on each tick would be faster?
+
+
+# Implementation notes
+
+
+## Promise resolution and chaining is handled iteratively
+
+By shuffling pending handlers from one owner to another, promises are
+resolved iteratively, allowing for "infinite" then chaining.
+
+```php
+<?php
+require 'vendor/autoload.php';
+
+use GuzzleHttp\Promise\Promise;
+
+$parent = new Promise();
+$p = $parent;
+
+for ($i = 0; $i < 1000; $i++) {
+    $p = $p->then(function ($v) {
+        // The stack size remains constant (a good thing)
+        echo xdebug_get_stack_depth() . ', ';
+        return $v + 1;
+    });
+}
+
+$parent->resolve(0);
+var_dump($p->wait()); // int(1000)
+
+```
+
+When a promise is fulfilled or rejected with a non-promise value, the promise
+then takes ownership of the handlers of each child promise and delivers values
+down the chain without using recursion.
+
+When a promise is resolved with another promise, the original promise transfers
+all of its pending handlers to the new promise. When the new promise is
+eventually resolved, all of the pending handlers are delivered the forwarded
+value.
+
+
+## A promise is the deferred.
+
+Some promise libraries implement promises using a deferred object to represent
+a computation and a promise object to represent the delivery of the result of
+the computation. This is a nice separation of computation and delivery because
+consumers of the promise cannot modify the value that will be eventually
+delivered.
+
+One side effect of being able to implement promise resolution and chaining
+iteratively is that you need to be able for one promise to reach into the state
+of another promise to shuffle around ownership of handlers. In order to achieve
+this without making the handlers of a promise publicly mutable, a promise is
+also the deferred value, allowing promises of the same parent class to reach
+into and modify the private properties of promises of the same type. While this
+does allow consumers of the value to modify the resolution or rejection of the
+deferred, it is a small price to pay for keeping the stack size constant.
+
+```php
+$promise = new Promise();
+$promise->then(function ($value) { echo $value; });
+// The promise is the deferred value, so you can deliver a value to it.
+$promise->resolve('foo');
+// prints "foo"
+```

+# CHANGELOG
+
+## 1.4.2 - 2017-03-20
+
+* Reverted BC break to `Uri::resolve` and `Uri::removeDotSegments` by removing 
+  calls to `trigger_error` when deprecated methods are invoked.
+
+## 1.4.1 - 2017-02-27
+
+* Reverted BC break by reintroducing behavior to automagically fix a URI with a
+  relative path and an authority by adding a leading slash to the path. It's only
+  deprecated now.
+* Added triggering of silenced deprecation warnings.
+
+## 1.4.0 - 2017-02-21
+
+* Fix `Stream::read` when length parameter <= 0.
+* `copy_to_stream` reads bytes in chunks instead of `maxLen` into memory.
+* Fix `ServerRequest::getUriFromGlobals` when `Host` header contains port.
+* Ensure `ServerRequest::getUriFromGlobals` returns a URI in absolute form.
+* Allow `parse_response` to parse a response without delimiting space and reason.
+* Ensure each URI modification results in a valid URI according to PSR-7 discussions.
+  Invalid modifications will throw an exception instead of returning a wrong URI or
+  doing some magic.
+  - `(new Uri)->withPath('foo')->withHost('example.com')` will throw an exception
+    because the path of a URI with an authority must start with a slash "/" or be empty
+  - `(new Uri())->withScheme('http')` will return `'http://localhost'`
+* Fix compatibility of URIs with `file` scheme and empty host.
+* Added common URI utility methods based on RFC 3986 (see documentation in the readme):
+  - `Uri::isDefaultPort`
+  - `Uri::isAbsolute`
+  - `Uri::isNetworkPathReference`
+  - `Uri::isAbsolutePathReference`
+  - `Uri::isRelativePathReference`
+  - `Uri::isSameDocumentReference`
+  - `Uri::composeComponents`
+  - `UriNormalizer::normalize`
+  - `UriNormalizer::isEquivalent`
+  - `UriResolver::relativize`
+* Deprecated `Uri::resolve` in favor of `UriResolver::resolve`
+* Deprecated `Uri::removeDotSegments` in favor of `UriResolver::removeDotSegments`
+
+## 1.3.1 - 2016-06-25
+
+* Fix `Uri::__toString` for network path references, e.g. `//example.org`.
+* Fix missing lowercase normalization for host.
+* Fix handling of URI components in case they are `'0'` in a lot of places,
+  e.g. as a user info password.
+* Fix `Uri::withAddedHeader` to correctly merge headers with different case.
+* Fix trimming of header values in `Uri::withAddedHeader`. Header values may
+  be surrounded by whitespace which should be ignored according to RFC 7230
+  Section 3.2.4. This does not apply to header names.
+* Fix `Uri::withAddedHeader` with an array of header values.
+* Fix `Uri::resolve` when base path has no slash and handling of fragment.
+* Fix handling of encoding in `Uri::with(out)QueryValue` so one can pass the
+  key/value both in encoded as well as decoded form to those methods. This is
+  consistent with withPath, withQuery etc.
+* Fix `ServerRequest::withoutAttribute` when attribute value is null.
+
+## 1.3.0 - 2016-04-13
+
+* Added remaining interfaces needed for full PSR7 compatibility
+  (ServerRequestInterface, UploadedFileInterface, etc.).
+* Added support for stream_for from scalars.
+* Can now extend Uri.
+* Fixed a bug in validating request methods by making it more permissive.
+
+## 1.2.3 - 2016-02-18
+
+* Fixed support in `GuzzleHttp\Psr7\CachingStream` for seeking forward on remote
+  streams, which can sometimes return fewer bytes than requested with `fread`.
+* Fixed handling of gzipped responses with FNAME headers.
+
+## 1.2.2 - 2016-01-22
+
+* Added support for URIs without any authority.
+* Added support for HTTP 451 'Unavailable For Legal Reasons.'
+* Added support for using '0' as a filename.
+* Added support for including non-standard ports in Host headers.
+
+## 1.2.1 - 2015-11-02
+
+* Now supporting negative offsets when seeking to SEEK_END.
+
+## 1.2.0 - 2015-08-15
+
+* Body as `"0"` is now properly added to a response.
+* Now allowing forward seeking in CachingStream.
+* Now properly parsing HTTP requests that contain proxy targets in
+  `parse_request`.
+* functions.php is now conditionally required.
+* user-info is no longer dropped when resolving URIs.
+
+## 1.1.0 - 2015-06-24
+
+* URIs can now be relative.
+* `multipart/form-data` headers are now overridden case-insensitively.
+* URI paths no longer encode the following characters because they are allowed
+  in URIs: "(", ")", "*", "!", "'"
+* A port is no longer added to a URI when the scheme is missing and no port is
+  present.
+
+## 1.0.0 - 2015-05-19
+
+Initial release.
+
+Currently unsupported:
+

+# PSR-7 Message Implementation
+
+This repository contains a full [PSR-7](http://www.php-fig.org/psr/psr-7/)
+message implementation, several stream decorators, and some helpful
+functionality like query string parsing.
+
+
+[![Build Status](https://travis-ci.org/guzzle/psr7.svg?branch=master)](https://travis-ci.org/guzzle/psr7)
+
+
+# Stream implementation
+
+This package comes with a number of stream implementations and stream
+decorators.
+
+
+## AppendStream
+
+`GuzzleHttp\Psr7\AppendStream`
+
+Reads from multiple streams, one after the other.
+
+```php
+use GuzzleHttp\Psr7;
+
+$a = Psr7\stream_for('abc, ');
+$b = Psr7\stream_for('123.');
+$composed = new Psr7\AppendStream([$a, $b]);
+
+$composed->addStream(Psr7\stream_for(' Above all listen to me'));
+
+echo $composed; // abc, 123. Above all listen to me.
+```
+
+
+## BufferStream
+
+`GuzzleHttp\Psr7\BufferStream`
+
+Provides a buffer stream that can be written to fill a buffer, and read
+from to remove bytes from the buffer.
+
+This stream returns a "hwm" metadata value that tells upstream consumers
+what the configured high water mark of the stream is, or the maximum
+preferred size of the buffer.
+
+```php
+use GuzzleHttp\Psr7;
+
+// When more than 1024 bytes are in the buffer, it will begin returning
+// false to writes. This is an indication that writers should slow down.
+$buffer = new Psr7\BufferStream(1024);
+```
+
+
+## CachingStream
+
+The CachingStream is used to allow seeking over previously read bytes on
+non-seekable streams. This can be useful when transferring a non-seekable
+entity body fails due to needing to rewind the stream (for example, resulting
+from a redirect). Data that is read from the remote stream will be buffered in
+a PHP temp stream so that previously read bytes are cached first in memory,
+then on disk.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for(fopen('http://www.google.com', 'r'));
+$stream = new Psr7\CachingStream($original);
+
+$stream->read(1024);
+echo $stream->tell();
+// 1024
+
+$stream->seek(0);
+echo $stream->tell();
+// 0
+```
+
+
+## DroppingStream
+
+`GuzzleHttp\Psr7\DroppingStream`
+
+Stream decorator that begins dropping data once the size of the underlying
+stream becomes too full.
+
+```php
+use GuzzleHttp\Psr7;
+
+// Create an empty stream
+$stream = Psr7\stream_for();
+
+// Start dropping data when the stream has more than 10 bytes
+$dropping = new Psr7\DroppingStream($stream, 10);
+
+$dropping->write('01234567890123456789');
+echo $stream; // 0123456789
+```
+
+
+## FnStream
+
+`GuzzleHttp\Psr7\FnStream`
+
+Compose stream implementations based on a hash of functions.
+
+Allows for easy testing and extension of a provided stream without needing
+to create a concrete class for a simple extension point.
+
+```php
+
+use GuzzleHttp\Psr7;
+
+$stream = Psr7\stream_for('hi');
+$fnStream = Psr7\FnStream::decorate($stream, [
+    'rewind' => function () use ($stream) {
+        echo 'About to rewind - ';
+        $stream->rewind();
+        echo 'rewound!';
+    }
+]);
+
+$fnStream->rewind();
+// Outputs: About to rewind - rewound!
+```
+
+
+## InflateStream
+
+`GuzzleHttp\Psr7\InflateStream`
+
+Uses PHP's zlib.inflate filter to inflate deflate or gzipped content.
+
+This stream decorator skips the first 10 bytes of the given stream to remove
+the gzip header, converts the provided stream to a PHP stream resource,
+then appends the zlib.inflate filter. The stream is then converted back
+to a Guzzle stream resource to be used as a Guzzle stream.
+
+
+## LazyOpenStream
+
+`GuzzleHttp\Psr7\LazyOpenStream`
+
+Lazily reads or writes to a file that is opened only after an IO operation
+take place on the stream.
+
+```php
+use GuzzleHttp\Psr7;
+
+$stream = new Psr7\LazyOpenStream('/path/to/file', 'r');
+// The file has not yet been opened...
+
+echo $stream->read(10);
+// The file is opened and read from only when needed.
+```
+
+
+## LimitStream
+
+`GuzzleHttp\Psr7\LimitStream`
+
+LimitStream can be used to read a subset or slice of an existing stream object.
+This can be useful for breaking a large file into smaller pieces to be sent in
+chunks (e.g. Amazon S3's multipart upload API).
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for(fopen('/tmp/test.txt', 'r+'));
+echo $original->getSize();
+// >>> 1048576
+
+// Limit the size of the body to 1024 bytes and start reading from byte 2048
+$stream = new Psr7\LimitStream($original, 1024, 2048);
+echo $stream->getSize();
+// >>> 1024
+echo $stream->tell();
+// >>> 0
+```
+
+
+## MultipartStream
+
+`GuzzleHttp\Psr7\MultipartStream`
+
+Stream that when read returns bytes for a streaming multipart or
+multipart/form-data stream.
+
+
+## NoSeekStream
+
+`GuzzleHttp\Psr7\NoSeekStream`
+
+NoSeekStream wraps a stream and does not allow seeking.
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for('foo');
+$noSeek = new Psr7\NoSeekStream($original);
+
+echo $noSeek->read(3);
+// foo
+var_export($noSeek->isSeekable());
+// false
+$noSeek->seek(0);
+var_export($noSeek->read(3));
+// NULL
+```
+
+
+## PumpStream
+
+`GuzzleHttp\Psr7\PumpStream`
+
+Provides a read only stream that pumps data from a PHP callable.
+
+When invoking the provided callable, the PumpStream will pass the amount of
+data requested to read to the callable. The callable can choose to ignore
+this value and return fewer or more bytes than requested. Any extra data
+returned by the provided callable is buffered internally until drained using
+the read() function of the PumpStream. The provided callable MUST return
+false when there is no more data to read.
+
+
+## Implementing stream decorators
+
+Creating a stream decorator is very easy thanks to the
+`GuzzleHttp\Psr7\StreamDecoratorTrait`. This trait provides methods that
+implement `Psr\Http\Message\StreamInterface` by proxying to an underlying
+stream. Just `use` the `StreamDecoratorTrait` and implement your custom
+methods.
+
+For example, let's say we wanted to call a specific function each time the last
+byte is read from a stream. This could be implemented by overriding the
+`read()` method.
+
+```php
+use Psr\Http\Message\StreamInterface;
+use GuzzleHttp\Psr7\StreamDecoratorTrait;
+
+class EofCallbackStream implements StreamInterface
+{
+    use StreamDecoratorTrait;
+
+    private $callback;
+
+    public function __construct(StreamInterface $stream, callable $cb)
+    {
+        $this->stream = $stream;
+        $this->callback = $cb;
+    }
+
+    public function read($length)
+    {
+        $result = $this->stream->read($length);
+
+        // Invoke the callback when EOF is hit.
+        if ($this->eof()) {
+            call_user_func($this->callback);
+        }
+
+        return $result;
+    }
+}
+```
+
+This decorator could be added to any existing stream and used like so:
+
+```php
+use GuzzleHttp\Psr7;
+
+$original = Psr7\stream_for('foo');
+
+$eofStream = new EofCallbackStream($original, function () {
+    echo 'EOF!';
+});
+
+$eofStream->read(2);
+$eofStream->read(1);
+// echoes "EOF!"
+$eofStream->seek(0);
+$eofStream->read(3);
+// echoes "EOF!"
+```
+
+
+## PHP StreamWrapper
+
+You can use the `GuzzleHttp\Psr7\StreamWrapper` class if you need to use a
+PSR-7 stream as a PHP stream resource.
+
+Use the `GuzzleHttp\Psr7\StreamWrapper::getResource()` method to create a PHP
+stream from a PSR-7 stream.
+
+```php
+use GuzzleHttp\Psr7\StreamWrapper;
+
+$stream = GuzzleHttp\Psr7\stream_for('hello!');
+$resource = StreamWrapper::getResource($stream);
+echo fread($resource, 6); // outputs hello!
+```
+
+
+# Function API
+
+There are various functions available under the `GuzzleHttp\Psr7` namespace.
+
+
+## `function str`
+
+`function str(MessageInterface $message)`
+
+Returns the string representation of an HTTP message.
+
+```php
+$request = new GuzzleHttp\Psr7\Request('GET', 'http://example.com');
+echo GuzzleHttp\Psr7\str($request);
+```
+
+
+## `function uri_for`
+
+`function uri_for($uri)`
+
+This function accepts a string or `Psr\Http\Message\UriInterface` and returns a
+UriInterface for the given value. If the value is already a `UriInterface`, it
+is returned as-is.
+
+```php
+$uri = GuzzleHttp\Psr7\uri_for('http://example.com');
+assert($uri === GuzzleHttp\Psr7\uri_for($uri));
+```
+
+
+## `function stream_for`
+
+`function stream_for($resource = '', array $options = [])`
+
+Create a new stream based on the input type.
+
+Options is an associative array that can contain the following keys:
+
+* - metadata: Array of custom metadata.
+* - size: Size of the stream.
+
+This method accepts the following `$resource` types:
+
+- `Psr\Http\Message\StreamInterface`: Returns the value as-is.
+- `string`: Creates a stream object that uses the given string as the contents.
+- `resource`: Creates a stream object that wraps the given PHP stream resource.
+- `Iterator`: If the provided value implements `Iterator`, then a read-only
+  stream object will be created that wraps the given iterable. Each time the
+  stream is read from, data from the iterator will fill a buffer and will be
+  continuously called until the buffer is equal to the requested read size.
+  Subsequent read calls will first read from the buffer and then call `next`
+  on the underlying iterator until it is exhausted.
+- `object` with `__toString()`: If the object has the `__toString()` method,
+  the object will be cast to a string and then a stream will be returned that
+  uses the string value.
+- `NULL`: When `null` is passed, an empty stream object is returned.
+- `callable` When a callable is passed, a read-only stream object will be
+  created that invokes the given callable. The callable is invoked with the
+  number of suggested bytes to read. The callable can return any number of
+  bytes, but MUST return `false` when there is no more data to return. The
+  stream object that wraps the callable will invoke the callable until the
+  number of requested bytes are available. Any additional bytes will be
+  buffered and used in subsequent reads.
+
+```php
+$stream = GuzzleHttp\Psr7\stream_for('foo');
+$stream = GuzzleHttp\Psr7\stream_for(fopen('/path/to/file', 'r'));
+
+$generator function ($bytes) {
+    for ($i = 0; $i < $bytes; $i++) {
+        yield ' ';
+    }
+}
+
+$stream = GuzzleHttp\Psr7\stream_for($generator(100));
+```
+
+
+## `function parse_header`
+
+`function parse_header($header)`
+
+Parse an array of header values containing ";" separated data into an array of
+associative arrays representing the header key value pair data of the header.
+When a parameter does not contain a value, but just contains a key, this
+function will inject a key with a '' string value.
+
+
+## `function normalize_header`
+
+`function normalize_header($header)`
+
+Converts an array of header values that may contain comma separated headers
+into an array of headers with no comma separated values.
+
+
+## `function modify_request`
+
+`function modify_request(RequestInterface $request, array $changes)`
+
+Clone and modify a request with the given changes. This method is useful for
+reducing the number of clones needed to mutate a message.
+
+The changes can be one of:
+
+- method: (string) Changes the HTTP method.
+- set_headers: (array) Sets the given headers.
+- remove_headers: (array) Remove the given headers.
+- body: (mixed) Sets the given body.
+- uri: (UriInterface) Set the URI.
+- query: (string) Set the query string value of the URI.
+- version: (string) Set the protocol version.
+
+
+## `function rewind_body`
+
+`function rewind_body(MessageInterface $message)`
+
+Attempts to rewind a message body and throws an exception on failure. The body
+of the message will only be rewound if a call to `tell()` returns a value other
+than `0`.
+
+
+## `function try_fopen`
+
+`function try_fopen($filename, $mode)`
+
+Safely opens a PHP stream resource using a filename.
+
+When fopen fails, PHP normally raises a warning. This function adds an error
+handler that checks for errors and throws an exception instead.
+
+
+## `function copy_to_string`
+
+`function copy_to_string(StreamInterface $stream, $maxLen = -1)`
+
+Copy the contents of a stream into a string until the given number of bytes
+have been read.
+
+
+## `function copy_to_stream`
+
+`function copy_to_stream(StreamInterface $source, StreamInterface $dest, $maxLen = -1)`
+
+Copy the contents of a stream into another stream until the given number of
+bytes have been read.
+
+
+## `function hash`
+
+`function hash(StreamInterface $stream, $algo, $rawOutput = false)`
+
+Calculate a hash of a Stream. This method reads the entire stream to calculate
+a rolling hash (based on PHP's hash_init functions).
+
+
+## `function readline`
+
+`function readline(StreamInterface $stream, $maxLength = null)`
+
+Read a line from the stream up to the maximum allowed buffer length.
+
+
+## `function parse_request`
+

+
+Parses a request message string into a request object.
+
+
+## `function parse_response`
+
+`function parse_response($message)`
+
+Parses a response message string into a response object.
+
+
+## `function parse_query`
+
+`function parse_query($str, $urlEncoding = true)`
+
+Parse a query string into an associative array.
+
+If multiple values are found for the same key, the value of that key value pair
+will become an array. This function does not parse nested PHP style arrays into
+an associative array (e.g., `foo[a]=1&foo[b]=2` will be parsed into
+`['foo[a]' => '1', 'foo[b]' => '2']`).
+
+
+## `function build_query`
+
+`function build_query(array $params, $encoding = PHP_QUERY_RFC3986)`
+
+Build a query string from an array of key value pairs.
+
+This function can use the return value of parse_query() to build a query string.
+This function does not modify the provided keys when an array is encountered
+(like http_build_query would).
+
+
+## `function mimetype_from_filename`
+
+`function mimetype_from_filename($filename)`
+
+Determines the mimetype of a file by looking at its extension.
+
+
+## `function mimetype_from_extension`
+
+`function mimetype_from_extension($extension)`
+
+Maps a file extensions to a mimetype.
+
+
+# Additional URI Methods
+
+Aside from the standard `Psr\Http\Message\UriInterface` implementation in form of the `GuzzleHttp\Psr7\Uri` class,
+this library also provides additional functionality when working with URIs as static methods.
+
+## URI Types
+
+An instance of `Psr\Http\Message\UriInterface` can either be an absolute URI or a relative reference.
+An absolute URI has a scheme. A relative reference is used to express a URI relative to another URI,
+the base URI. Relative references can be divided into several forms according to
+[RFC 3986 Section 4.2](https://tools.ietf.org/html/rfc3986#section-4.2):
+
+- network-path references, e.g. `//example.com/path`
+- absolute-path references, e.g. `/path`
+- relative-path references, e.g. `subpath`
+
+The following methods can be used to identify the type of the URI.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolute`
+
+`public static function isAbsolute(UriInterface $uri): bool`
+
+Whether the URI is absolute, i.e. it has a scheme.
+
+### `GuzzleHttp\Psr7\Uri::isNetworkPathReference`
+
+`public static function isNetworkPathReference(UriInterface $uri): bool`
+
+Whether the URI is a network-path reference. A relative reference that begins with two slash characters is
+termed an network-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isAbsolutePathReference`
+
+`public static function isAbsolutePathReference(UriInterface $uri): bool`
+
+Whether the URI is a absolute-path reference. A relative reference that begins with a single slash character is
+termed an absolute-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isRelativePathReference`
+
+`public static function isRelativePathReference(UriInterface $uri): bool`
+
+Whether the URI is a relative-path reference. A relative reference that does not begin with a slash character is
+termed a relative-path reference.
+
+### `GuzzleHttp\Psr7\Uri::isSameDocumentReference`
+
+`public static function isSameDocumentReference(UriInterface $uri, UriInterface $base = null): bool`
+
+Whether the URI is a same-document reference. A same-document reference refers to a URI that is, aside from its
+fragment component, identical to the base URI. When no base URI is given, only an empty URI reference
+(apart from its fragment) is considered a same-document reference.
+
+## URI Components
+
+Additional methods to work with URI components.
+
+### `GuzzleHttp\Psr7\Uri::isDefaultPort`
+
+`public static function isDefaultPort(UriInterface $uri): bool`
+
+Whether the URI has the default port of the current scheme. `Psr\Http\Message\UriInterface::getPort` may return null
+or the standard port. This method can be used independently of the implementation.
+
+### `GuzzleHttp\Psr7\Uri::composeComponents`
+
+`public static function composeComponents($scheme, $authority, $path, $query, $fragment): string`
+
+Composes a URI reference string from its various components according to
+[RFC 3986 Section 5.3](https://tools.ietf.org/html/rfc3986#section-5.3). Usually this method does not need to be called
+manually but instead is used indirectly via `Psr\Http\Message\UriInterface::__toString`.
+
+### `GuzzleHttp\Psr7\Uri::fromParts`
+
+`public static function fromParts(array $parts): UriInterface`
+
+Creates a URI from a hash of [`parse_url`](http://php.net/manual/en/function.parse-url.php) components.
+
+
+### `GuzzleHttp\Psr7\Uri::withQueryValue`
+
+`public static function withQueryValue(UriInterface $uri, $key, $value): UriInterface`
+
+Creates a new URI with a specific query string value. Any existing query string values that exactly match the
+provided key are removed and replaced with the given key value pair. A value of null will set the query string
+key without a value, e.g. "key" instead of "key=value".
+
+
+### `GuzzleHttp\Psr7\Uri::withoutQueryValue`
+
+`public static function withoutQueryValue(UriInterface $uri, $key): UriInterface`
+
+Creates a new URI with a specific query string value removed. Any existing query string values that exactly match the
+provided key are removed.
+
+## Reference Resolution
+
+`GuzzleHttp\Psr7\UriResolver` provides methods to resolve a URI reference in the context of a base URI according
+to [RFC 3986 Section 5](https://tools.ietf.org/html/rfc3986#section-5). This is for example also what web browsers
+do when resolving a link in a website based on the current request URI.
+
+### `GuzzleHttp\Psr7\UriResolver::resolve`
+
+`public static function resolve(UriInterface $base, UriInterface $rel): UriInterface`
+
+Converts the relative URI into a new URI that is resolved against the base URI.
+
+### `GuzzleHttp\Psr7\UriResolver::removeDotSegments`
+
+`public static function removeDotSegments(string $path): string`
+
+Removes dot segments from a path and returns the new path according to
+[RFC 3986 Section 5.2.4](https://tools.ietf.org/html/rfc3986#section-5.2.4).
+
+### `GuzzleHttp\Psr7\UriResolver::relativize`
+
+`public static function relativize(UriInterface $base, UriInterface $target): UriInterface`
+
+Returns the target URI as a relative reference from the base URI. This method is the counterpart to resolve():
+
+```php
+(string) $target === (string) UriResolver::resolve($base, UriResolver::relativize($base, $target))
+```
+
+One use-case is to use the current request URI as base URI and then generate relative links in your documents
+to reduce the document size or offer self-contained downloadable document archives.
+
+```php
+$base = new Uri('http://example.com/a/b/');
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/c'));  // prints 'c'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/x/y'));  // prints '../x/y'.
+echo UriResolver::relativize($base, new Uri('http://example.com/a/b/?q')); // prints '?q'.
+echo UriResolver::relativize($base, new Uri('http://example.org/a/b/'));   // prints '//example.org/a/b/'.
+```
+
+## Normalization and Comparison
+
+`GuzzleHttp\Psr7\UriNormalizer` provides methods to normalize and compare URIs according to
+[RFC 3986 Section 6](https://tools.ietf.org/html/rfc3986#section-6).
+
+### `GuzzleHttp\Psr7\UriNormalizer::normalize`
+
+`public static function normalize(UriInterface $uri, $flags = self::PRESERVING_NORMALIZATIONS): UriInterface`
+
+Returns a normalized URI. The scheme and host component are already normalized to lowercase per PSR-7 UriInterface.
+This methods adds additional normalizations that can be configured with the `$flags` parameter which is a bitmask
+of normalizations to apply. The following normalizations are available:
+
+- `UriNormalizer::PRESERVING_NORMALIZATIONS`
+
+    Default normalizations which only include the ones that preserve semantics.
+
+- `UriNormalizer::CAPITALIZE_PERCENT_ENCODING`
+
+    All letters within a percent-encoding triplet (e.g., "%3A") are case-insensitive, and should be capitalized.
+
+    Example: `http://example.org/a%c2%b1b` → `http://example.org/a%C2%B1b`
+
+- `UriNormalizer::DECODE_UNRESERVED_CHARACTERS`
+
+    Decodes percent-encoded octets of unreserved characters. For consistency, percent-encoded octets in the ranges of
+    ALPHA (%41–%5A and %61–%7A), DIGIT (%30–%39), hyphen (%2D), period (%2E), underscore (%5F), or tilde (%7E) should
+    not be created by URI producers and, when found in a URI, should be decoded to their corresponding unreserved
+    characters by URI normalizers.
+
+    Example: `http://example.org/%7Eusern%61me/` → `http://example.org/~username/`
+
+- `UriNormalizer::CONVERT_EMPTY_PATH`
+
+    Converts the empty path to "/" for http and https URIs.
+
+    Example: `http://example.org` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DEFAULT_HOST`
+
+    Removes the default host of the given URI scheme from the URI. Only the "file" scheme defines the default host
+    "localhost". All of `file:/myfile`, `file:///myfile`, and `file://localhost/myfile` are equivalent according to
+    RFC 3986.
+
+    Example: `file://localhost/myfile` → `file:///myfile`
+
+- `UriNormalizer::REMOVE_DEFAULT_PORT`
+
+    Removes the default port of the given URI scheme from the URI.
+
+    Example: `http://example.org:80/` → `http://example.org/`
+
+- `UriNormalizer::REMOVE_DOT_SEGMENTS`
+
+    Removes unnecessary dot-segments. Dot-segments in relative-path references are not removed as it would
+    change the semantics of the URI reference.
+
+    Example: `http://example.org/../a/b/../c/./d.html` → `http://example.org/a/c/d.html`
+
+- `UriNormalizer::REMOVE_DUPLICATE_SLASHES`
+
+    Paths which include two or more adjacent slashes are converted to one. Webservers usually ignore duplicate slashes
+    and treat those URIs equivalent. But in theory those URIs do not need to be equivalent. So this normalization
+    may change the semantics. Encoded slashes (%2F) are not removed.
+
+    Example: `http://example.org//foo///bar.html` → `http://example.org/foo/bar.html`
+
+- `UriNormalizer::SORT_QUERY_PARAMETERS`
+
+    Sort query parameters with their values in alphabetical order. However, the order of parameters in a URI may be
+    significant (this is not defined by the standard). So this normalization is not safe and may change the semantics
+    of the URI.
+
+    Example: `?lang=en&article=fred` → `?article=fred&lang=en`
+
+### `GuzzleHttp\Psr7\UriNormalizer::isEquivalent`
+
+`public static function isEquivalent(UriInterface $uri1, UriInterface $uri2, $normalizations = self::PRESERVING_NORMALIZATIONS): bool`
+
+Whether two URIs can be considered equivalent. Both URIs are normalized automatically before comparison with the given
+`$normalizations` bitmask. The method also accepts relative URI references and returns true when they are equivalent.
+This of course assumes they will be resolved against the same base URI. If this is not the case, determination of
+equivalence or difference of relative references does not mean anything.

The method will find the best fitting aspect ratio of your given width and height on the current image automatically, cut it out and resize it to the given dimension. You may pass an optional Closure callback as third parameter, to prevent possible upsizing and a custom position of the cutout as fourth parameter.
+ * @method \Intervention\Image\Image gamma(float $correction)                                                                                                             Performs a gamma correction operation on the current image.

Pass an optional Closure callback as third parameter, to apply additional constraints like preventing possible upsizing.
+ * @method \Intervention\Image\Image insert(mixed $source, string $position = 'top-left', int $x = 0, int $y = 0)                                                 Paste a given image source over the current image with an optional position and a offset coordinate. This method can be used to apply another image as watermark because the transparency values are maintained.
+ * @method \Intervention\Image\Image interlace(boolean $interlace = true)                                                                                                 Determine whether an image should be encoded in interlaced or standard mode by toggling interlace mode with a boolean parameter. If an JPEG image is set interlaced the image will be processed as a progressive JPEG.
+ * @method \Intervention\Image\Image invert()                                                                                                                             Reverses all colors of the current image.

Mask will be resized to the current image size. By default a greyscale version of the mask is converted to alpha values, but you can set mask_with_alpha to apply the actual alpha channel. Any transparency values of the current image will be maintained.
+ * @method \Intervention\Image\Image opacity(int $transparency)                                                                                                       Set the opacity in percent of the current image ranging from 100% for opaque and 0% for full transparency.
+ * @method \Intervention\Image\Image orientate()                                                                                                                          This method reads the EXIF image profile setting 'Orientation' and performs a rotation on the image to display the image correctly.
+ * @method mixed                     pickColor(int $x, int $y, string $format = 'array')                                                                          Pick a color at point x, y out of current image and return in optional given format.
+ * @method \Intervention\Image\Image pixel(mixed $color, int $x, int $y)                                                                                          Draw a single pixel in given color on x, y position.
+ * @method \Intervention\Image\Image pixelate(int $size)                                                                                                              Applies a pixelation effect to the current image with a given size of pixels.

To contraint the resize command, pass an optional Closure callback as third parameter.
+ * @method \Intervention\Image\Image resizeCanvas(int $width, int $height, string $anchor = 'center', boolean $relative = false, mixed $bgcolor = null)           Resize the boundaries of the current image to given width and height. An anchor can be defined to determine from what point of the image the resizing is going to happen. Set the mode to relative to add or subtract the given width or height to the actual image dimensions. You can also pass a background color for the emerging area of the image.
+ * @method mixed                     response(string $format = null, int $quality = 90)                                                                               Sends HTTP response with current image in given format and quality.

+
+OAuth 1 Client is an OAuth [RFC 5849 standards-compliant](http://tools.ietf.org/html/rfc5849) library for authenticating against OAuth 1 servers.
+
+It has built in support for:
+
+- Bitbucket
+- Trello
+- Tumblr
+- Twitter
+- Xing
+
+Adding support for other providers is trivial. The library requires PHP 5.3+ and is PSR-2 compatible.
+
+### Third-Party Providers
+
+If you would like to support other providers, please make them available as a Composer package, then link to them
+below.
+
+These providers allow integration with other providers not supported by `oauth1-client`. They may require an older version
+so please help them out with a pull request if you notice this.
+
+- [Intuit](https://packagist.org/packages/wheniwork/oauth1-intuit)
+- [500px](https://packagist.org/packages/mechant/oauth1-500px)
+- [Etsy](https://packagist.org/packages/y0lk/oauth1-etsy)
+- [Xero](https://packagist.org/packages/Invoiced/oauth1-xero)
+
+#### Terminology (as per the RFC 5849 specification):
+
+    client
+        An HTTP client (per [RFC2616]) capable of making OAuth-
+        authenticated requests (Section 3).
+
+    server
+        An HTTP server (per [RFC2616]) capable of accepting OAuth-
+        authenticated requests (Section 3).
+
+    protected resource
+        An access-restricted resource that can be obtained from the
+        server using an OAuth-authenticated request (Section 3).
+
+    resource owner
+        An entity capable of accessing and controlling protected
+        resources by using credentials to authenticate with the server.
+
+    credentials
+        Credentials are a pair of a unique identifier and a matching
+        shared secret.  OAuth defines three classes of credentials:
+        client, temporary, and token, used to identify and authenticate
+        the client making the request, the authorization request, and
+        the access grant, respectively.
+
+    token
+        A unique identifier issued by the server and used by the client
+        to associate authenticated requests with the resource owner
+        whose authorization is requested or has been obtained by the
+        client.  Tokens have a matching shared-secret that is used by
+        the client to establish its ownership of the token, and its
+        authority to represent the resource owner.
+
+    The original community specification used a somewhat different
+    terminology that maps to this specifications as follows (original
+    community terms provided on left):
+
+    Consumer:  client
+
+    Service Provider:  server
+
+    User:  resource owner
+
+    Consumer Key and Secret:  client credentials
+
+    Request Token and Secret:  temporary credentials
+
+    Access Token and Secret:  token credentials
+
+
+## Install
+
+Via Composer
+
+```shell
+$ composer require league/oauth1-client
+```
+
+
+## Usage
+
+### Bitbucket
+
+```php
+$server = new League\OAuth1\Client\Server\Bitbucket(array(
+    'identifier' => 'your-identifier',
+    'secret' => 'your-secret',
+    'callback_uri' => "http://your-callback-uri/",
+));
+```
+
+### Trello
+
+```php
+$server =  new League\OAuth1\Client\Server\Trello(array(
+    'identifier' => 'your-identifier',
+    'secret' => 'your-secret',
+    'callback_uri' => 'http://your-callback-uri/',
+    'name' => 'your-application-name', // optional, defaults to null
+    'expiration' => 'your-application-expiration', // optional ('never', '1day', '2days'), defaults to '1day'
+    'scope' => 'your-application-scope' // optional ('read', 'read,write'), defaults to 'read'
+));
+```
+
+### Tumblr
+
+```php
+$server = new League\OAuth1\Client\Server\Tumblr(array(
+    'identifier' => 'your-identifier',
+    'secret' => 'your-secret',
+    'callback_uri' => "http://your-callback-uri/",
+));
+```
+
+### Twitter
+
+```php
+$server = new League\OAuth1\Client\Server\Twitter(array(
+    'identifier' => 'your-identifier',
+    'secret' => 'your-secret',
+    'callback_uri' => "http://your-callback-uri/",
+));
+```
+
+### Xing
+
+```php
+$server = new League\OAuth1\Client\Server\Xing(array(
+    'identifier' => 'your-consumer-key',
+    'secret' => 'your-consumer-secret',
+    'callback_uri' => "http://your-callback-uri/",
+));
+```
+
+### Showing a Login Button
+
+To begin, it's advisable that you include a login button on your website. Most servers (Twitter, Tumblr etc) have resources available for making buttons that are familiar to users. Some servers actually require you use their buttons as part of their terms.
+
+```html
+<a href="authenticate.php">Login With Twitter</a>
+```
+
+### Retrieving Temporary Credentials
+
+The first step to authenticating with OAuth 1 is to retrieve temporary credentials. These have been referred to as **request tokens** in earlier versions of OAuth 1.
+
+To do this, we'll retrieve and store temporary credentials in the session, and redirect the user to the server:
+
+```php
+// Retrieve temporary credentials
+$temporaryCredentials = $server->getTemporaryCredentials();
+
+// Store credentials in the session, we'll need them later
+$_SESSION['temporary_credentials'] = serialize($temporaryCredentials);
+session_write_close();
+
+// Second part of OAuth 1.0 authentication is to redirect the
+// resource owner to the login screen on the server.
+$server->authorize($temporaryCredentials);
+```
+
+The user will be redirected to the familiar login screen on the server, where they will login to their account and authorise your app to access their data.
+
+### Retrieving Token Credentials
+
+Once the user has authenticated (or denied) your application, they will be redirected to the `callback_uri` which you specified when creating the server.
+
+> Note, some servers (such as Twitter) require that the callback URI you specify when authenticating matches what you registered with their app. This is to stop a potential third party impersonating you. This is actually part of the protocol however some servers choose to ignore this.
+>
+> Because of this, we actually require you specify a callback URI for all servers, regardless of whether the server requires it or not. This is good practice.
+
+You'll need to handle when the user is redirected back. This will involve retrieving token credentials, which you may then use to make calls to the server on behalf of the user. These have been referred to as **access tokens** in earlier versions of OAuth 1.
+
+```php
+if (isset($_GET['oauth_token']) && isset($_GET['oauth_verifier'])) {
+    // Retrieve the temporary credentials we saved before
+    $temporaryCredentials = unserialize($_SESSION['temporary_credentials']);
+
+    // We will now retrieve token credentials from the server
+    $tokenCredentials = $server->getTokenCredentials($temporaryCredentials, $_GET['oauth_token'], $_GET['oauth_verifier']);
+}
+```
+
+Now, you may choose to do what you need with the token credentials. You may store them in a database, in the session, or use them as one-off and then forget about them.
+
+All credentials, (`client credentials`, `temporary credentials` and `token credentials`) all implement `League\OAuth1\Client\Credentials\CredentialsInterface` and have two sets of setters and getters exposed:
+
+```php
+var_dump($tokenCredentials->getIdentifier());
+var_dump($tokenCredentials->getSecret());
+```
+
+In earlier versions of OAuth 1, the token credentials identifier and token credentials secret were referred to as **access token** and  **access token secret**. Don't be scared by the new terminology here - they are the same. This package is using the exact terminology in the RFC 5849 OAuth 1 standard.
+
+> Twitter will send back an error message in the `denied` query string parameter, allowing you to provide feedback. Some servers do not send back an error message, but rather do not provide the successful `oauth_token` and `oauth_verifier` parameters.
+
+### Accessing User Information
+
+Now you have token credentials stored somewhere, you may use them to make calls against the server, as an authenticated user.
+
+While this package is not intended to be a wrapper for every server's API, it does include basic methods that you may use to retrieve limited information. An example of where this may be useful is if you are using social logins, you only need limited information to confirm who the user is.
+
+The four exposed methods are:
+
+```php
+// User is an instance of League\OAuth1\Client\Server\User
+$user = $server->getUserDetails($tokenCredentials);
+
+// UID is a string / integer unique representation of the user
+$uid = $server->getUserUid($tokenCredentials);
+
+// Email is either a string or null (as some providers do not supply this data)
+$email = $server->getUserEmail($tokenCredentials);
+
+// Screen name is also known as a username (Twitter handle etc)
+$screenName = $server->getUserScreenName($tokenCredentials);
+```
+
+> `League\OAuth1\Client\Server\User` exposes a number of default public properties and also stores any additional data in an extra array - `$user->extra`. You may also iterate over a user's properties as if it was an array, `foreach ($user as $key => $value)`.
+
+## Examples
+
+Examples may be found under the [resources/examples](https://github.com/thephpleague/oauth1-client/tree/master/resources/examples) directory, which take the usage instructions here and go into a bit more depth. They are working examples that would only you substitute in your client credentials to have working.
+

+RFC 5849                        OAuth 1.0                     April 2010
+
+
+1.  Introduction
+
+   The OAuth protocol was originally created by a small community of web
+   developers from a variety of websites and other Internet services who
+   wanted to solve the common problem of enabling delegated access to
+   protected resources.  The resulting OAuth protocol was stabilized at
+   version 1.0 in October 2007, and revised in June 2009 (Revision A) as
+   published at <http://oauth.net/core/1.0a>.
+
+   This specification provides an informational documentation of OAuth
+   Core 1.0 Revision A, addresses several errata reported since that
+   time, and makes numerous editorial clarifications.  While this
+   specification is not an item of the IETF's OAuth Working Group, which
+   at the time of writing is working on an OAuth version that can be
+   appropriate for publication on the standards track, it has been
+   transferred to the IETF for change control by authors of the original
+   work.
+
+   In the traditional client-server authentication model, the client
+   uses its credentials to access its resources hosted by the server.
+   With the increasing use of distributed web services and cloud
+   computing, third-party applications require access to these server-
+   hosted resources.
+
+   OAuth introduces a third role to the traditional client-server
+   authentication model: the resource owner.  In the OAuth model, the
+   client (which is not the resource owner, but is acting on its behalf)
+   requests access to resources controlled by the resource owner, but
+   hosted by the server.  In addition, OAuth allows the server to verify
+   not only the resource owner authorization, but also the identity of
+   the client making the request.
+
+   OAuth provides a method for clients to access server resources on
+   behalf of a resource owner (such as a different client or an end-
+   user).  It also provides a process for end-users to authorize third-
+   party access to their server resources without sharing their
+   credentials (typically, a username and password pair), using user-
+   agent redirections.
+
+   For example, a web user (resource owner) can grant a printing service
+   (client) access to her private photos stored at a photo sharing
+   service (server), without sharing her username and password with the
+   printing service.  Instead, she authenticates directly with the photo
+   sharing service which issues the printing service delegation-specific
+   credentials.
+
+

+
+
+   In order for the client to access resources, it first has to obtain
+   permission from the resource owner.  This permission is expressed in
+   the form of a token and matching shared-secret.  The purpose of the
+   token is to make it unnecessary for the resource owner to share its
+   credentials with the client.  Unlike the resource owner credentials,
+   tokens can be issued with a restricted scope and limited lifetime,
+   and revoked independently.
+
+   This specification consists of two parts.  The first part defines a
+   redirection-based user-agent process for end-users to authorize
+   client access to their resources, by authenticating directly with the
+   server and provisioning tokens to the client for use with the
+   authentication method.  The second part defines a method for making
+   authenticated HTTP [RFC2616] requests using two sets of credentials,
+   one identifying the client making the request, and a second
+   identifying the resource owner on whose behalf the request is being
+   made.
+
+   The use of OAuth with any transport protocol other than [RFC2616] is
+   undefined.
+
+1.1.  Terminology
+
+   client
+         An HTTP client (per [RFC2616]) capable of making OAuth-
+         authenticated requests (Section 3).
+
+   server
+         An HTTP server (per [RFC2616]) capable of accepting OAuth-
+         authenticated requests (Section 3).
+
+   protected resource
+         An access-restricted resource that can be obtained from the
+         server using an OAuth-authenticated request (Section 3).
+
+   resource owner
+         An entity capable of accessing and controlling protected
+         resources by using credentials to authenticate with the server.
+
+   credentials
+         Credentials are a pair of a unique identifier and a matching
+         shared secret.  OAuth defines three classes of credentials:
+         client, temporary, and token, used to identify and authenticate
+         the client making the request, the authorization request, and
+         the access grant, respectively.

+
+
+   token
+         A unique identifier issued by the server and used by the client
+         to associate authenticated requests with the resource owner
+         whose authorization is requested or has been obtained by the
+         client.  Tokens have a matching shared-secret that is used by
+         the client to establish its ownership of the token, and its
+         authority to represent the resource owner.
+
+   The original community specification used a somewhat different
+   terminology that maps to this specifications as follows (original
+   community terms provided on left):
+
+   Consumer:  client
+
+   Service Provider:  server
+
+   User:  resource owner
+
+   Consumer Key and Secret:  client credentials
+
+   Request Token and Secret:  temporary credentials
+
+   Access Token and Secret:  token credentials
+
+1.2.  Example
+
+   Jane (resource owner) has recently uploaded some private vacation
+   photos (protected resources) to her photo sharing site
+   'photos.example.net' (server).  She would like to use the
+   'printer.example.com' website (client) to print one of these photos.
+   Typically, Jane signs into 'photos.example.net' using her username
+   and password.
+
+   However, Jane does not wish to share her username and password with
+   the 'printer.example.com' website, which needs to access the photo in
+   order to print it.  In order to provide its users with better
+   service, 'printer.example.com' has signed up for a set of
+   'photos.example.net' client credentials ahead of time:
+
+   Client Identifier
+         dpf43f3p2l4k3l03
+
+   Client Shared-Secret:
+         kd94hf93k423kf44
+
+   The 'printer.example.com' website has also configured its application
+   to use the protocol endpoints listed in the 'photos.example.net' API
+   documentation, which use the "HMAC-SHA1" signature method:

+
+   Token Request URI:
+         https://photos.example.net/token
+
+   Before 'printer.example.com' can ask Jane to grant it access to the
+   photos, it must first establish a set of temporary credentials with
+   'photos.example.net' to identify the delegation request.  To do so,
+   the client sends the following HTTPS [RFC2818] request to the server:
+
+     POST /initiate HTTP/1.1
+     Host: photos.example.net
+     Authorization: OAuth realm="Photos",
+        oauth_consumer_key="dpf43f3p2l4k3l03",
+        oauth_signature_method="HMAC-SHA1",
+        oauth_timestamp="137131200",
+        oauth_nonce="wIjqoS",
+        oauth_callback="http%3A%2F%2Fprinter.example.com%2Fready",
+        oauth_signature="74KNZJeDHnMBp0EMJ9ZHt%2FXKycU%3D"
+
+   The server validates the request and replies with a set of temporary
+   credentials in the body of the HTTP response (line breaks are for
+   display purposes only):
+
+     HTTP/1.1 200 OK
+     Content-Type: application/x-www-form-urlencoded
+
+     oauth_token=hh5s93j4hdidpola&oauth_token_secret=hdhd0244k9j7ao03&
+     oauth_callback_confirmed=true
+
+   The client redirects Jane's user-agent to the server's Resource Owner
+   Authorization endpoint to obtain Jane's approval for accessing her
+   private photos:
+
+     https://photos.example.net/authorize?oauth_token=hh5s93j4hdidpola
+
+   The server requests Jane to sign in using her username and password
+   and if successful, asks her to approve granting 'printer.example.com'
+   access to her private photos.  Jane approves the request and her
+   user-agent is redirected to the callback URI provided by the client
+   in the previous request (line breaks are for display purposes only):
+
+     http://printer.example.com/ready?
+     oauth_token=hh5s93j4hdidpola&oauth_verifier=hfdp7dh39dks9884

+
+
+   The callback request informs the client that Jane completed the
+   authorization process.  The client then requests a set of token
+   credentials using its temporary credentials (over a secure Transport
+   Layer Security (TLS) channel):
+
+     POST /token HTTP/1.1
+     Host: photos.example.net
+     Authorization: OAuth realm="Photos",
+        oauth_consumer_key="dpf43f3p2l4k3l03",
+        oauth_token="hh5s93j4hdidpola",
+        oauth_signature_method="HMAC-SHA1",
+        oauth_timestamp="137131201",
+        oauth_nonce="walatlh",
+        oauth_verifier="hfdp7dh39dks9884",
+        oauth_signature="gKgrFCywp7rO0OXSjdot%2FIHF7IU%3D"
+
+   The server validates the request and replies with a set of token
+   credentials in the body of the HTTP response:
+
+     HTTP/1.1 200 OK
+     Content-Type: application/x-www-form-urlencoded
+
+     oauth_token=nnch734d00sl2jdk&oauth_token_secret=pfkkdhi9sl3r4s00
+
+   With a set of token credentials, the client is now ready to request
+   the private photo:
+
+     GET /photos?file=vacation.jpg&size=original HTTP/1.1
+     Host: photos.example.net
+     Authorization: OAuth realm="Photos",
+        oauth_consumer_key="dpf43f3p2l4k3l03",
+        oauth_token="nnch734d00sl2jdk",
+        oauth_signature_method="HMAC-SHA1",
+        oauth_timestamp="137131202",
+        oauth_nonce="chapoH",
+        oauth_signature="MdpQcU8iPSUjWoN%2FUDMsK2sui9I%3D"
+
+   The 'photos.example.net' server validates the request and responds
+   with the requested photo. 'printer.example.com' is able to continue
+   accessing Jane's private photos using the same set of token
+   credentials for the duration of Jane's authorization, or until Jane
+   revokes access.

+
+
+2.  Redirection-Based Authorization
+
+   OAuth uses tokens to represent the authorization granted to the
+   client by the resource owner.  Typically, token credentials are
+   issued by the server at the resource owner's request, after
+   authenticating the resource owner's identity (usually using a
+   username and password).
+
+   There are many ways in which a server can facilitate the provisioning
+   of token credentials.  This section defines one such way, using HTTP
+   redirections and the resource owner's user-agent.  This redirection-
+   based authorization method includes three steps:
+
+   1.  The client obtains a set of temporary credentials from the server
+       (in the form of an identifier and shared-secret).  The temporary
+       credentials are used to identify the access request throughout
+       the authorization process.
+
+   2.  The resource owner authorizes the server to grant the client's
+       access request (identified by the temporary credentials).
+
+   3.  The client uses the temporary credentials to request a set of
+       token credentials from the server, which will enable it to access
+       the resource owner's protected resources.
+
+   The server MUST revoke the temporary credentials after being used
+   once to obtain the token credentials.  It is RECOMMENDED that the
+   temporary credentials have a limited lifetime.  Servers SHOULD enable
+   resource owners to revoke token credentials after they have been
+   issued to clients.
+
+   In order for the client to perform these steps, the server needs to
+   advertise the URIs of the following three endpoints:
+
+   Temporary Credential Request
+         The endpoint used by the client to obtain a set of temporary
+         credentials as described in Section 2.1.
+
+   Resource Owner Authorization
+         The endpoint to which the resource owner is redirected to grant
+         authorization as described in Section 2.2.
+
+   Token Request
+         The endpoint used by the client to request a set of token
+         credentials using the set of temporary credentials as described
+         in Section 2.3.

+
+
+   The three URIs advertised by the server MAY include a query component
+   as defined by [RFC3986], Section 3, but if present, the query MUST
+   NOT contain any parameters beginning with the "oauth_" prefix, to
+   avoid conflicts with the protocol parameters added to the URIs when
+   used.
+
+   The methods in which the server advertises and documents its three
+   endpoints are beyond the scope of this specification.  Clients should
+   avoid making assumptions about the size of tokens and other server-
+   generated values, which are left undefined by this specification.  In
+   addition, protocol parameters MAY include values that require
+   encoding when transmitted.  Clients and servers should not make
+   assumptions about the possible range of their values.
+
+2.1.  Temporary Credentials
+
+   The client obtains a set of temporary credentials from the server by
+   making an authenticated (Section 3) HTTP "POST" request to the
+   Temporary Credential Request endpoint (unless the server advertises
+   another HTTP request method for the client to use).  The client
+   constructs a request URI by adding the following REQUIRED parameter
+   to the request (in addition to the other protocol parameters, using
+   the same parameter transmission method):
+
+   oauth_callback:  An absolute URI back to which the server will
+                    redirect the resource owner when the Resource Owner
+                    Authorization step (Section 2.2) is completed.  If
+                    the client is unable to receive callbacks or a
+                    callback URI has been established via other means,
+                    the parameter value MUST be set to "oob" (case
+                    sensitive), to indicate an out-of-band
+                    configuration.
+
+   Servers MAY specify additional parameters.
+
+   When making the request, the client authenticates using only the
+   client credentials.  The client MAY omit the empty "oauth_token"
+   protocol parameter from the request and MUST use the empty string as
+   the token secret value.
+
+   Since the request results in the transmission of plain text
+   credentials in the HTTP response, the server MUST require the use of
+   a transport-layer mechanisms such as TLS or Secure Socket Layer (SSL)
+   (or a secure channel with equivalent protections).
+
+
+

+
+
+   For example, the client makes the following HTTPS request:
+
+     POST /request_temp_credentials HTTP/1.1
+     Host: server.example.com
+     Authorization: OAuth realm="Example",
+        oauth_consumer_key="jd83jd92dhsh93js",
+        oauth_signature_method="PLAINTEXT",
+        oauth_callback="http%3A%2F%2Fclient.example.net%2Fcb%3Fx%3D1",
+        oauth_signature="ja893SD9%26"
+
+   The server MUST verify (Section 3.2) the request and if valid,
+   respond back to the client with a set of temporary credentials (in
+   the form of an identifier and shared-secret).  The temporary
+   credentials are included in the HTTP response body using the
+   "application/x-www-form-urlencoded" content type as defined by
+   [W3C.REC-html40-19980424] with a 200 status code (OK).
+
+   The response contains the following REQUIRED parameters:
+
+   oauth_token
+         The temporary credentials identifier.
+
+   oauth_token_secret
+         The temporary credentials shared-secret.
+
+   oauth_callback_confirmed
+         MUST be present and set to "true".  The parameter is used to
+         differentiate from previous versions of the protocol.
+
+   Note that even though the parameter names include the term 'token',
+   these credentials are not token credentials, but are used in the next
+   two steps in a similar manner to token credentials.
+
+   For example (line breaks are for display purposes only):
+
+     HTTP/1.1 200 OK
+     Content-Type: application/x-www-form-urlencoded
+
+     oauth_token=hdk48Djdsa&oauth_token_secret=xyz4992k83j47x0b&
+     oauth_callback_confirmed=true
+
+2.2.  Resource Owner Authorization
+
+   Before the client requests a set of token credentials from the
+   server, it MUST send the user to the server to authorize the request.
+   The client constructs a request URI by adding the following REQUIRED
+   query parameter to the Resource Owner Authorization endpoint URI:

+
+
+   oauth_token
+         The temporary credentials identifier obtained in Section 2.1 in
+         the "oauth_token" parameter.  Servers MAY declare this
+         parameter as OPTIONAL, in which case they MUST provide a way
+         for the resource owner to indicate the identifier through other
+         means.
+
+   Servers MAY specify additional parameters.
+
+   The client directs the resource owner to the constructed URI using an
+   HTTP redirection response, or by other means available to it via the
+   resource owner's user-agent.  The request MUST use the HTTP "GET"
+   method.
+
+   For example, the client redirects the resource owner's user-agent to
+   make the following HTTPS request:
+
+     GET /authorize_access?oauth_token=hdk48Djdsa HTTP/1.1
+     Host: server.example.com
+
+   The way in which the server handles the authorization request,
+   including whether it uses a secure channel such as TLS/SSL is beyond
+   the scope of this specification.  However, the server MUST first
+   verify the identity of the resource owner.
+
+   When asking the resource owner to authorize the requested access, the
+   server SHOULD present to the resource owner information about the
+   client requesting access based on the association of the temporary
+   credentials with the client identity.  When displaying any such
+   information, the server SHOULD indicate if the information has been
+   verified.
+
+   After receiving an authorization decision from the resource owner,
+   the server redirects the resource owner to the callback URI if one
+   was provided in the "oauth_callback" parameter or by other means.
+
+   To make sure that the resource owner granting access is the same
+   resource owner returning back to the client to complete the process,
+   the server MUST generate a verification code: an unguessable value
+   passed to the client via the resource owner and REQUIRED to complete
+   the process.  The server constructs the request URI by adding the
+   following REQUIRED parameters to the callback URI query component:
+
+   oauth_token
+         The temporary credentials identifier received from the client.
+
+

+
+
+   oauth_verifier
+         The verification code.
+
+   If the callback URI already includes a query component, the server
+   MUST append the OAuth parameters to the end of the existing query.
+
+   For example, the server redirects the resource owner's user-agent to
+   make the following HTTP request:
+
+     GET /cb?x=1&oauth_token=hdk48Djdsa&oauth_verifier=473f82d3 HTTP/1.1
+     Host: client.example.net
+
+   If the client did not provide a callback URI, the server SHOULD
+   display the value of the verification code, and instruct the resource
+   owner to manually inform the client that authorization is completed.
+   If the server knows a client to be running on a limited device, it
+   SHOULD ensure that the verifier value is suitable for manual entry.
+
+2.3.  Token Credentials
+
+   The client obtains a set of token credentials from the server by
+   making an authenticated (Section 3) HTTP "POST" request to the Token
+   Request endpoint (unless the server advertises another HTTP request
+   method for the client to use).  The client constructs a request URI
+   by adding the following REQUIRED parameter to the request (in
+   addition to the other protocol parameters, using the same parameter
+   transmission method):
+
+   oauth_verifier
+         The verification code received from the server in the previous
+         step.
+
+   When making the request, the client authenticates using the client
+   credentials as well as the temporary credentials.  The temporary
+   credentials are used as a substitute for token credentials in the
+   authenticated request and transmitted using the "oauth_token"
+   parameter.
+
+   Since the request results in the transmission of plain text
+   credentials in the HTTP response, the server MUST require the use of
+   a transport-layer mechanism such as TLS or SSL (or a secure channel
+   with equivalent protections).

+
+   For example, the client makes the following HTTPS request:

+        oauth_verifier="473f82d3",
+        oauth_signature="ja893SD9%26xyz4992k83j47x0b"
+
+   The server MUST verify (Section 3.2) the validity of the request,
+   ensure that the resource owner has authorized the provisioning of
+   token credentials to the client, and ensure that the temporary
+   credentials have not expired or been used before.  The server MUST
+   also verify the verification code received from the client.  If the
+   request is valid and authorized, the token credentials are included
+   in the HTTP response body using the
+   "application/x-www-form-urlencoded" content type as defined by
+   [W3C.REC-html40-19980424] with a 200 status code (OK).
+
+   The response contains the following REQUIRED parameters:
+
+   oauth_token
+         The token identifier.
+
+   oauth_token_secret
+         The token shared-secret.

+
+     oauth_token=j49ddk933skd9dks&oauth_token_secret=ll399dj47dskfjdk
+
+   The server must retain the scope, duration, and other attributes
+   approved by the resource owner, and enforce these restrictions when
+   receiving a client request made with the token credentials issued.
+
+   Once the client receives and stores the token credentials, it can
+   proceed to access protected resources on behalf of the resource owner
+   by making authenticated requests (Section 3) using the client
+   credentials together with the token credentials received.

+
+
+3.  Authenticated Requests
+
+   The HTTP authentication methods defined by [RFC2617] enable clients
+   to make authenticated HTTP requests.  Clients using these methods
+   gain access to protected resources by using their credentials
+   (typically, a username and password pair), which allow the server to
+   verify their authenticity.  Using these methods for delegation
+   requires the client to assume the role of the resource owner.
+
+   OAuth provides a method designed to include two sets of credentials
+   with each request, one to identify the client, and another to
+   identify the resource owner.  Before a client can make authenticated
+   requests on behalf of the resource owner, it must obtain a token
+   authorized by the resource owner.  Section 2 provides one such method
+   through which the client can obtain a token authorized by the
+   resource owner.
+
+   The client credentials take the form of a unique identifier and an
+   associated shared-secret or RSA key pair.  Prior to making
+   authenticated requests, the client establishes a set of credentials
+   with the server.  The process and requirements for provisioning these
+   are outside the scope of this specification.  Implementers are urged
+   to consider the security ramifications of using client credentials,
+   some of which are described in Section 4.6.
+
+   Making authenticated requests requires prior knowledge of the
+   server's configuration.  OAuth includes multiple methods for
+   transmitting protocol parameters with requests (Section 3.5), as well
+   as multiple methods for the client to prove its rightful ownership of
+   the credentials used (Section 3.4).  The way in which clients
+   discover the required configuration is outside the scope of this
+   specification.
+
+3.1.  Making Requests
+
+   An authenticated request includes several protocol parameters.  Each
+   parameter name begins with the "oauth_" prefix, and the parameter
+   names and values are case sensitive.  Clients make authenticated
+   requests by calculating the values of a set of protocol parameters
+   and adding them to the HTTP request as follows:
+
+   1.  The client assigns value to each of these REQUIRED (unless
+       specified otherwise) protocol parameters:

+

+
+
+       oauth_consumer_key
+         The identifier portion of the client credentials (equivalent to
+         a username).  The parameter name reflects a deprecated term
+         (Consumer Key) used in previous revisions of the specification,
+         and has been retained to maintain backward compatibility.
+
+       oauth_token
+         The token value used to associate the request with the resource
+         owner.  If the request is not associated with a resource owner
+         (no token available), clients MAY omit the parameter.
+
+       oauth_signature_method
+         The name of the signature method used by the client to sign the
+         request, as defined in Section 3.4.
+
+       oauth_timestamp
+         The timestamp value as defined in Section 3.3.  The parameter
+         MAY be omitted when using the "PLAINTEXT" signature method.
+
+       oauth_nonce
+         The nonce value as defined in Section 3.3.  The parameter MAY
+         be omitted when using the "PLAINTEXT" signature method.
+
+       oauth_version
+         OPTIONAL.  If present, MUST be set to "1.0".  Provides the
+         version of the authentication process as defined in this
+         specification.
+
+   2.  The protocol parameters are added to the request using one of the
+       transmission methods listed in Section 3.5.  Each parameter MUST
+       NOT appear more than once per request.
+
+   3.  The client calculates and assigns the value of the
+       "oauth_signature" parameter as described in Section 3.4 and adds
+       the parameter to the request using the same method as in the
+       previous step.
+
+   4.  The client sends the authenticated HTTP request to the server.
+
+   For example, to make the following HTTP request authenticated (the
+   "c2&a3=2+q" string in the following examples is used to illustrate
+   the impact of a form-encoded entity-body):
+
+     POST /request?b5=%3D%253D&a3=a&c%40=&a2=r%20b HTTP/1.1

+
+   The client assigns values to the following protocol parameters using
+   its client credentials, token credentials, the current timestamp, a
+   uniquely generated nonce, and indicates that it will use the
+   "HMAC-SHA1" signature method:
+
+     oauth_consumer_key:     9djdj82h48djs9d2
+     oauth_token:            kkk9d7dh3k39sjv7

+     oauth_timestamp:        137131201
+     oauth_nonce:            7d8f3e4a
+
+   The client adds the protocol parameters to the request using the
+   OAuth HTTP "Authorization" header field:
+
+     Authorization: OAuth realm="Example",
+                    oauth_consumer_key="9djdj82h48djs9d2",

+                    oauth_nonce="7d8f3e4a"
+
+   Then, it calculates the value of the "oauth_signature" parameter
+   (using client secret "j49sk3j29djd" and token secret "dh893hdasih9"),
+   adds it to the request, and sends the HTTP request to the server:

+     Host: example.com

+      via the "oauth_signature" parameter.

+
+
+   o  If using the "HMAC-SHA1" or "RSA-SHA1" signature methods, ensuring
+      that the combination of nonce/timestamp/token (if present)
+      received from the client has not been used before in a previous
+      request (the server MAY reject requests with stale timestamps as
+      described in Section 3.3).
+
+   o  If a token is present, verifying the scope and status of the
+      client authorization as represented by the token (the server MAY
+      choose to restrict token usage to the client to which it was
+      issued).
+
+   o  If the "oauth_version" parameter is present, ensuring its value is
+      "1.0".
+
+   If the request fails verification, the server SHOULD respond with the
+   appropriate HTTP response status code.  The server MAY include
+   further details about why the request was rejected in the response
+   body.
+
+   The server SHOULD return a 400 (Bad Request) status code when
+   receiving a request with unsupported parameters, an unsupported
+   signature method, missing parameters, or duplicated protocol
+   parameters.  The server SHOULD return a 401 (Unauthorized) status
+   code when receiving a request with invalid client credentials, an
+   invalid or expired token, an invalid signature, or an invalid or used
+   nonce.
+
+3.3.  Nonce and Timestamp
+
+   The timestamp value MUST be a positive integer.  Unless otherwise
+   specified by the server's documentation, the timestamp is expressed
+   in the number of seconds since January 1, 1970 00:00:00 GMT.
+
+   A nonce is a random string, uniquely generated by the client to allow
+   the server to verify that a request has never been made before and
+   helps prevent replay attacks when requests are made over a non-secure
+   channel.  The nonce value MUST be unique across all requests with the
+   same timestamp, client credentials, and token combinations.
+
+   To avoid the need to retain an infinite number of nonce values for
+   future checks, servers MAY choose to restrict the time period after
+   which a request with an old timestamp is rejected.  Note that this
+   restriction implies a level of synchronization between the client's
+   and server's clocks.  Servers applying such a restriction MAY provide
+   a way for the client to sync with the server's clock; alternatively,
+   both systems could synchronize with a trusted time service.  Details
+   of clock synchronization strategies are beyond the scope of this
+   specification.

+
+3.4.  Signature
+
+   OAuth-authenticated requests can have two sets of credentials: those
+   passed via the "oauth_consumer_key" parameter and those in the
+   "oauth_token" parameter.  In order for the server to verify the
+   authenticity of the request and prevent unauthorized access, the
+   client needs to prove that it is the rightful owner of the
+   credentials.  This is accomplished using the shared-secret (or RSA
+   key) part of each set of credentials.
+
+   OAuth provides three methods for the client to prove its rightful
+   ownership of the credentials: "HMAC-SHA1", "RSA-SHA1", and
+   "PLAINTEXT".  These methods are generally referred to as signature
+   methods, even though "PLAINTEXT" does not involve a signature.  In
+   addition, "RSA-SHA1" utilizes an RSA key instead of the shared-
+   secrets associated with the client credentials.
+
+   OAuth does not mandate a particular signature method, as each
+   implementation can have its own unique requirements.  Servers are
+   free to implement and document their own custom methods.
+   Recommending any particular method is beyond the scope of this
+   specification.  Implementers should review the Security
+   Considerations section (Section 4) before deciding on which method to
+   support.
+
+   The client declares which signature method is used via the
+   "oauth_signature_method" parameter.  It then generates a signature
+   (or a string of an equivalent value) and includes it in the
+   "oauth_signature" parameter.  The server verifies the signature as
+   specified for each method.
+
+   The signature process does not change the request or its parameters,
+   with the exception of the "oauth_signature" parameter.
+
+3.4.1.  Signature Base String
+
+   The signature base string is a consistent, reproducible concatenation
+   of several of the HTTP request elements into a single string.  The
+   string is used as an input to the "HMAC-SHA1" and "RSA-SHA1"
+   signature methods.
+
+   The signature base string includes the following components of the
+   HTTP request:
+
+   o  The HTTP request method (e.g., "GET", "POST", etc.).
+
+   o  The authority as declared by the HTTP "Host" request header field.

+
+
+   o  The path and query components of the request resource URI.
+
+   o  The protocol parameters excluding the "oauth_signature".
+
+   o  Parameters included in the request entity-body if they comply with
+      the strict restrictions defined in Section 3.4.1.3.
+
+   The signature base string does not cover the entire HTTP request.
+   Most notably, it does not include the entity-body in most requests,
+   nor does it include most HTTP entity-headers.  It is important to
+   note that the server cannot verify the authenticity of the excluded
+   request components without using additional protections such as SSL/
+   TLS or other methods.
+
+3.4.1.1.  String Construction
+
+   The signature base string is constructed by concatenating together,
+   in order, the following HTTP request elements:
+
+   1.  The HTTP request method in uppercase.  For example: "HEAD",
+       "GET", "POST", etc.  If the request uses a custom HTTP method, it
+       MUST be encoded (Section 3.6).
+
+   2.  An "&" character (ASCII code 38).
+
+   3.  The base string URI from Section 3.4.1.2, after being encoded
+       (Section 3.6).
+
+   4.  An "&" character (ASCII code 38).
+
+   5.  The request parameters as normalized in Section 3.4.1.3.2, after
+       being encoded (Section 3.6).
+
+   For example, the HTTP request:
+
+     POST /request?b5=%3D%253D&a3=a&c%40=&a2=r%20b HTTP/1.1
+     Host: example.com
+     Content-Type: application/x-www-form-urlencoded

+
+3.4.1.2.  Base String URI
+
+   The scheme, authority, and path of the request resource URI [RFC3986]
+   are included by constructing an "http" or "https" URI representing
+   the request resource (without the query or fragment) as follows:
+
+   1.  The scheme and host MUST be in lowercase.
+
+   2.  The host and port values MUST match the content of the HTTP
+       request "Host" header field.
+
+   3.  The port MUST be included if it is not the default port for the
+       scheme, and MUST be excluded if it is the default.  Specifically,
+       the port MUST be excluded when making an HTTP request [RFC2616]
+       to port 80 or when making an HTTPS request [RFC2818] to port 443.
+       All other non-default port numbers MUST be included.
+
+   For example, the HTTP request:
+
+     GET /r%20v/X?id=123 HTTP/1.1
+     Host: EXAMPLE.COM:80
+
+   is represented by the base string URI: "http://example.com/r%20v/X".
+
+   In another example, the HTTPS request:
+
+     GET /?q=1 HTTP/1.1
+     Host: www.example.net:8080
+
+   is represented by the base string URI:
+   "https://www.example.net:8080/".
+
+3.4.1.3.  Request Parameters
+
+   In order to guarantee a consistent and reproducible representation of
+   the request parameters, the parameters are collected and decoded to
+   their original decoded form.  They are then sorted and encoded in a
+   particular manner that is often different from their original
+   encoding scheme, and concatenated into a single string.

+
+
+3.4.1.3.1.  Parameter Sources
+
+   The parameters from the following sources are collected into a single
+   list of name/value pairs:
+
+   o  The query component of the HTTP request URI as defined by
+      [RFC3986], Section 3.4.  The query component is parsed into a list
+      of name/value pairs by treating it as an
+      "application/x-www-form-urlencoded" string, separating the names
+      and values and decoding them as defined by
+      [W3C.REC-html40-19980424], Section 17.13.4.
+
+   o  The OAuth HTTP "Authorization" header field (Section 3.5.1) if
+      present.  The header's content is parsed into a list of name/value
+      pairs excluding the "realm" parameter if present.  The parameter
+      values are decoded as defined by Section 3.5.1.
+
+   o  The HTTP request entity-body, but only if all of the following
+      conditions are met:
+
+      *  The entity-body is single-part.
+
+      *  The entity-body follows the encoding requirements of the
+         "application/x-www-form-urlencoded" content-type as defined by
+         [W3C.REC-html40-19980424].
+
+      *  The HTTP request entity-header includes the "Content-Type"
+         header field set to "application/x-www-form-urlencoded".
+
+      The entity-body is parsed into a list of decoded name/value pairs
+      as described in [W3C.REC-html40-19980424], Section 17.13.4.
+
+   The "oauth_signature" parameter MUST be excluded from the signature
+   base string if present.  Parameters not explicitly included in the
+   request MUST be excluded from the signature base string (e.g., the
+   "oauth_version" parameter when omitted).

+3.4.1.3.2.  Parameters Normalization
+
+   The parameters collected in Section 3.4.1.3 are normalized into a
+   single string as follows:
+
+   1.  First, the name and value of each parameter are encoded
+       (Section 3.6).
+
+   2.  The parameters are sorted by name, using ascending byte value
+       ordering.  If two or more parameters share the same name, they
+       are sorted by their value.
+
+   3.  The name of each parameter is concatenated to its corresponding
+       value using an "=" character (ASCII code 61) as a separator, even
+       if the value is empty.
+
+   4.  The sorted name/value pairs are concatenated together into a
+       single string by using an "&" character (ASCII code 38) as
+       separator.
+
+   For example, the list of parameters from the previous section would
+   be normalized as follows:

+3.4.2.  HMAC-SHA1
+
+   The "HMAC-SHA1" signature method uses the HMAC-SHA1 signature

+
+     digest = HMAC-SHA1 (key, text)
+
+   The HMAC-SHA1 function variables are used in following way:

+           Section 3.4.1.1.
+
+   key     is set to the concatenated values of:
+
+           1.  The client shared-secret, after being encoded
+               (Section 3.6).
+
+           2.  An "&" character (ASCII code 38), which MUST be included
+               even when either secret is empty.
+
+           3.  The token shared-secret, after being encoded
+               (Section 3.6).
+
+   digest  is used to set the value of the "oauth_signature" protocol
+           parameter, after the result octet string is base64-encoded
+           per [RFC2045], Section 6.8.

+   The "RSA-SHA1" signature method uses the RSASSA-PKCS1-v1_5 signature
+   algorithm as defined in [RFC3447], Section 8.2 (also known as
+   PKCS#1), using SHA-1 as the hash function for EMSA-PKCS1-v1_5.  To
+   use this method, the client MUST have established client credentials
+   with the server that included its RSA public key (in a manner that is
+   beyond the scope of this specification).
+
+   The signature base string is signed using the client's RSA private
+   key per [RFC3447], Section 8.2.1:
+
+     S = RSASSA-PKCS1-V1_5-SIGN (K, M)
+
+   Where:
+
+   K     is set to the client's RSA private key,
+
+   M     is set to the value of the signature base string from
+         Section 3.4.1.1, and

+
+
+   S     is the result signature used to set the value of the
+         "oauth_signature" protocol parameter, after the result octet
+         string is base64-encoded per [RFC2045] section 6.8.
+
+   The server verifies the signature per [RFC3447] section 8.2.2:
+
+     RSASSA-PKCS1-V1_5-VERIFY ((n, e), M, S)
+
+   Where:
+
+   (n, e) is set to the client's RSA public key,
+
+   M      is set to the value of the signature base string from
+          Section 3.4.1.1, and
+
+   S      is set to the octet string value of the "oauth_signature"
+          protocol parameter received from the client.
+
+3.4.4.  PLAINTEXT
+
+   The "PLAINTEXT" method does not employ a signature algorithm.  It
+   MUST be used with a transport-layer mechanism such as TLS or SSL (or
+   sent over a secure channel with equivalent protections).  It does not
+   utilize the signature base string or the "oauth_timestamp" and
+   "oauth_nonce" parameters.
+
+   The "oauth_signature" protocol parameter is set to the concatenated
+   value of:
+
+   1.  The client shared-secret, after being encoded (Section 3.6).
+
+   2.  An "&" character (ASCII code 38), which MUST be included even
+       when either secret is empty.
+
+   3.  The token shared-secret, after being encoded (Section 3.6).
+
+3.5.  Parameter Transmission
+
+   When making an OAuth-authenticated request, protocol parameters as
+   well as any other parameter using the "oauth_" prefix SHALL be
+   included in the request using one and only one of the following
+   locations, listed in order of decreasing preference:
+
+   1.  The HTTP "Authorization" header field as described in
+       Section 3.5.1.
+
+   2.  The HTTP request entity-body as described in Section 3.5.2.

+
+   3.  The HTTP request URI query as described in Section 3.5.3.
+
+   In addition to these three methods, future extensions MAY define
+   other methods for including protocol parameters in the request.
+
+3.5.1.  Authorization Header
+
+   Protocol parameters can be transmitted using the HTTP "Authorization"
+   header field as defined by [RFC2617] with the auth-scheme name set to
+   "OAuth" (case insensitive).
+
+   For example:
+
+     Authorization: OAuth realm="Example",
+        oauth_consumer_key="0685bd9184jfhq22",
+        oauth_token="ad180jjd733klru7",
+        oauth_signature_method="HMAC-SHA1",
+        oauth_signature="wOJIO9A2W5mFwDgiDvZbTSMK%2FPY%3D",
+        oauth_timestamp="137131200",
+        oauth_nonce="4572616e48616d6d65724c61686176",
+        oauth_version="1.0"
+
+   Protocol parameters SHALL be included in the "Authorization" header
+   field as follows:
+
+   1.  Parameter names and values are encoded per Parameter Encoding
+       (Section 3.6).
+
+   2.  Each parameter's name is immediately followed by an "=" character
+       (ASCII code 61), a """ character (ASCII code 34), the parameter
+       value (MAY be empty), and another """ character (ASCII code 34).
+
+   3.  Parameters are separated by a "," character (ASCII code 44) and
+       OPTIONAL linear whitespace per [RFC2617].
+
+   4.  The OPTIONAL "realm" parameter MAY be added and interpreted per
+       [RFC2617] section 1.2.
+
+   Servers MAY indicate their support for the "OAuth" auth-scheme by
+   returning the HTTP "WWW-Authenticate" response header field upon
+   client requests for protected resources.  As per [RFC2617], such a
+   response MAY include additional HTTP "WWW-Authenticate" header
+   fields:
+
+   For example:
+
+     WWW-Authenticate: OAuth realm="http://server.example.com/"

+
+
+   The realm parameter defines a protection realm per [RFC2617], Section
+   1.2.
+
+3.5.2.  Form-Encoded Body
+
+   Protocol parameters can be transmitted in the HTTP request entity-
+   body, but only if the following REQUIRED conditions are met:
+
+   o  The entity-body is single-part.
+
+   o  The entity-body follows the encoding requirements of the
+      "application/x-www-form-urlencoded" content-type as defined by
+      [W3C.REC-html40-19980424].
+
+   o  The HTTP request entity-header includes the "Content-Type" header
+      field set to "application/x-www-form-urlencoded".
+
+   For example (line breaks are for display purposes only):
+
+     oauth_consumer_key=0685bd9184jfhq22&oauth_token=ad180jjd733klr
+     u7&oauth_signature_method=HMAC-SHA1&oauth_signature=wOJIO9A2W5
+     mFwDgiDvZbTSMK%2FPY%3D&oauth_timestamp=137131200&oauth_nonce=4
+     572616e48616d6d65724c61686176&oauth_version=1.0
+
+   The entity-body MAY include other request-specific parameters, in
+   which case, the protocol parameters SHOULD be appended following the
+   request-specific parameters, properly separated by an "&" character
+   (ASCII code 38).
+
+3.5.3.  Request URI Query
+
+   Protocol parameters can be transmitted by being added to the HTTP
+   request URI as a query parameter as defined by [RFC3986], Section 3.
+
+   For example (line breaks are for display purposes only):
+
+     GET /example/path?oauth_consumer_key=0685bd9184jfhq22&
+     oauth_token=ad180jjd733klru7&oauth_signature_method=HM
+     AC-SHA1&oauth_signature=wOJIO9A2W5mFwDgiDvZbTSMK%2FPY%
+     3D&oauth_timestamp=137131200&oauth_nonce=4572616e48616
+     d6d65724c61686176&oauth_version=1.0 HTTP/1.1
+
+   The request URI MAY include other request-specific query parameters,
+   in which case, the protocol parameters SHOULD be appended following
+   the request-specific parameters, properly separated by an "&"
+   character (ASCII code 38).

+
+
+3.6.  Percent Encoding
+
+   Existing percent-encoding methods do not guarantee a consistent
+   construction of the signature base string.  The following percent-
+   encoding method is not defined to replace the existing encoding
+   methods defined by [RFC3986] and [W3C.REC-html40-19980424].  It is
+   used only in the construction of the signature base string and the
+   "Authorization" header field.
+
+   This specification defines the following method for percent-encoding
+   strings:
+
+   1.  Text values are first encoded as UTF-8 octets per [RFC3629] if
+       they are not already.  This does not include binary values that
+       are not intended for human consumption.
+
+   2.  The values are then escaped using the [RFC3986] percent-encoding
+       (%XX) mechanism as follows:
+
+       *  Characters in the unreserved character set as defined by
+          [RFC3986], Section 2.3 (ALPHA, DIGIT, "-", ".", "_", "~") MUST
+          NOT be encoded.
+
+       *  All other characters MUST be encoded.
+
+       *  The two hexadecimal characters used to represent encoded
+          characters MUST be uppercase.
+
+   This method is different from the encoding scheme used by the
+   "application/x-www-form-urlencoded" content-type (for example, it
+   encodes space characters as "%20" and not using the "+" character).
+   It MAY be different from the percent-encoding functions provided by
+   web-development frameworks (e.g., encode different characters, use
+   lowercase hexadecimal characters).
+
+4.  Security Considerations
+
+   As stated in [RFC2617], the greatest sources of risks are usually
+   found not in the core protocol itself but in policies and procedures
+   surrounding its use.  Implementers are strongly encouraged to assess
+   how this protocol addresses their security requirements.
+
+4.1.  RSA-SHA1 Signature Method
+
+   Authenticated requests made with "RSA-SHA1" signatures do not use the
+   token shared-secret, or any provisioned client shared-secret.  This
+   means the request relies completely on the secrecy of the private key
+   used by the client to sign requests.

+RFC 5849                        OAuth 1.0                     April 2010
+
+
+4.2.  Confidentiality of Requests
+
+   While this protocol provides a mechanism for verifying the integrity
+   of requests, it provides no guarantee of request confidentiality.
+   Unless further precautions are taken, eavesdroppers will have full
+   access to request content.  Servers should carefully consider the
+   kinds of data likely to be sent as part of such requests, and should
+   employ transport-layer security mechanisms to protect sensitive
+   resources.
+
+4.3.  Spoofing by Counterfeit Servers
+
+   This protocol makes no attempt to verify the authenticity of the
+   server.  A hostile party could take advantage of this by intercepting
+   the client's requests and returning misleading or otherwise incorrect
+   responses.  Service providers should consider such attacks when
+   developing services using this protocol, and should require
+   transport-layer security for any requests where the authenticity of
+   the server or of request responses is an issue.
+
+4.4.  Proxying and Caching of Authenticated Content
+
+   The HTTP Authorization scheme (Section 3.5.1) is optional.  However,
+   [RFC2616] relies on the "Authorization" and "WWW-Authenticate" header
+   fields to distinguish authenticated content so that it can be
+   protected.  Proxies and caches, in particular, may fail to adequately
+   protect requests not using these header fields.
+
+   For example, private authenticated content may be stored in (and thus
+   retrievable from) publicly accessible caches.  Servers not using the
+   HTTP "Authorization" header field should take care to use other
+   mechanisms, such as the "Cache-Control" header field, to ensure that
+   authenticated content is protected.
+
+4.5.  Plaintext Storage of Credentials
+
+   The client shared-secret and token shared-secret function the same
+   way passwords do in traditional authentication systems.  In order to
+   compute the signatures used in methods other than "RSA-SHA1", the
+   server must have access to these secrets in plaintext form.  This is
+   in contrast, for example, to modern operating systems, which store
+   only a one-way hash of user credentials.
+
+   If an attacker were to gain access to these secrets -- or worse, to
+   the server's database of all such secrets -- he or she would be able
+   to perform any action on behalf of any resource owner.  Accordingly,
+   it is critical that servers protect these secrets from unauthorized
+   access.

+
+
+4.6.  Secrecy of the Client Credentials
+
+   In many cases, the client application will be under the control of
+   potentially untrusted parties.  For example, if the client is a
+   desktop application with freely available source code or an
+   executable binary, an attacker may be able to download a copy for
+   analysis.  In such cases, attackers will be able to recover the
+   client credentials.
+
+   Accordingly, servers should not use the client credentials alone to
+   verify the identity of the client.  Where possible, other factors
+   such as IP address should be used as well.
+
+4.7.  Phishing Attacks
+
+   Wide deployment of this and similar protocols may cause resource
+   owners to become inured to the practice of being redirected to
+   websites where they are asked to enter their passwords.  If resource
+   owners are not careful to verify the authenticity of these websites
+   before entering their credentials, it will be possible for attackers
+   to exploit this practice to steal resource owners' passwords.
+
+   Servers should attempt to educate resource owners about the risks
+   phishing attacks pose, and should provide mechanisms that make it
+   easy for resource owners to confirm the authenticity of their sites.
+   Client developers should consider the security implications of how
+   they interact with a user-agent (e.g., separate window, embedded),
+   and the ability of the end-user to verify the authenticity of the
+   server website.
+
+4.8.  Scoping of Access Requests
+
+   By itself, this protocol does not provide any method for scoping the
+   access rights granted to a client.  However, most applications do
+   require greater granularity of access rights.  For example, servers
+   may wish to make it possible to grant access to some protected
+   resources but not others, or to grant only limited access (such as
+   read-only access) to those protected resources.
+
+   When implementing this protocol, servers should consider the types of
+   access resource owners may wish to grant clients, and should provide
+   mechanisms to do so.  Servers should also take care to ensure that
+   resource owners understand the access they are granting, as well as
+   any risks that may be involved.

+
+
+4.9.  Entropy of Secrets
+
+   Unless a transport-layer security protocol is used, eavesdroppers
+   will have full access to authenticated requests and signatures, and
+   will thus be able to mount offline brute-force attacks to recover the
+   credentials used.  Servers should be careful to assign shared-secrets
+   that are long enough, and random enough, to resist such attacks for
+   at least the length of time that the shared-secrets are valid.
+
+   For example, if shared-secrets are valid for two weeks, servers
+   should ensure that it is not possible to mount a brute force attack
+   that recovers the shared-secret in less than two weeks.  Of course,
+   servers are urged to err on the side of caution, and use the longest
+   secrets reasonable.
+
+   It is equally important that the pseudo-random number generator
+   (PRNG) used to generate these secrets be of sufficiently high
+   quality.  Many PRNG implementations generate number sequences that
+   may appear to be random, but that nevertheless exhibit patterns or
+   other weaknesses that make cryptanalysis or brute force attacks
+   easier.  Implementers should be careful to use cryptographically
+   secure PRNGs to avoid these problems.
+
+4.10.  Denial-of-Service / Resource-Exhaustion Attacks
+
+   This specification includes a number of features that may make
+   resource exhaustion attacks against servers possible.  For example,
+   this protocol requires servers to track used nonces.  If an attacker
+   is able to use many nonces quickly, the resources required to track
+   them may exhaust available capacity.  And again, this protocol can
+   require servers to perform potentially expensive computations in
+   order to verify the signature on incoming requests.  An attacker may
+   exploit this to perform a denial-of-service attack by sending a large
+   number of invalid requests to the server.
+
+   Resource Exhaustion attacks are by no means specific to this
+   specification.  However, implementers should be careful to consider
+   the additional avenues of attack that this protocol exposes, and
+   design their implementations accordingly.  For example, entropy
+   starvation typically results in either a complete denial of service
+   while the system waits for new entropy or else in weak (easily
+   guessable) secrets.  When implementing this protocol, servers should
+   consider which of these presents a more serious risk for their
+   application and design accordingly.
+

+
+
+4.11.  SHA-1 Cryptographic Attacks
+
+   SHA-1, the hash algorithm used in "HMAC-SHA1" and "RSA-SHA1"
+   signature methods, has been shown to have a number of cryptographic
+   weaknesses that significantly reduce its resistance to collision
+   attacks.  While these weaknesses do not seem to affect the use of
+   SHA-1 with the Hash-based Message Authentication Code (HMAC) and
+   should not affect the "HMAC-SHA1" signature method, it may affect the
+   use of the "RSA-SHA1" signature method.  NIST has announced that it
+   will phase out use of SHA-1 in digital signatures by 2010
+   [NIST_SHA-1Comments].
+
+   Practically speaking, these weaknesses are difficult to exploit, and
+   by themselves do not pose a significant risk to users of this
+   protocol.  They may, however, make more efficient attacks possible,
+   and servers should take this into account when considering whether
+   SHA-1 provides an adequate level of security for their applications.
+
+4.12.  Signature Base String Limitations
+
+   The signature base string has been designed to support the signature
+   methods defined in this specification.  Those designing additional
+   signature methods, should evaluated the compatibility of the
+   signature base string with their security requirements.
+
+   Since the signature base string does not cover the entire HTTP
+   request, such as most request entity-body, most entity-headers, and
+   the order in which parameters are sent, servers should employ
+   additional mechanisms to protect such elements.
+
+4.13.  Cross-Site Request Forgery (CSRF)
+
+   Cross-Site Request Forgery (CSRF) is a web-based attack whereby HTTP
+   requests are transmitted from a user that the website trusts or has
+   authenticated.  CSRF attacks on authorization approvals can allow an
+   attacker to obtain authorization to protected resources without the
+   consent of the User.  Servers SHOULD strongly consider best practices
+   in CSRF prevention at all the protocol authorization endpoints.
+
+   CSRF attacks on OAuth callback URIs hosted by clients are also
+   possible.  Clients should prevent CSRF attacks on OAuth callback URIs
+   by verifying that the resource owner at the client site intended to
+   complete the OAuth negotiation with the server.  The methods for
+   preventing such CSRF attacks are beyond the scope of this
+   specification.

+
+
+4.14.  User Interface Redress
+
+   Servers should protect the authorization process against user
+   interface (UI) redress attacks (also known as "clickjacking").  As of
+   the time of this writing, no complete defenses against UI redress are
+   available.  Servers can mitigate the risk of UI redress attacks using
+   the following techniques:
+
+   o  JavaScript frame busting.
+
+   o  JavaScript frame busting, and requiring that browsers have
+      JavaScript enabled on the authorization page.
+
+   o  Browser-specific anti-framing techniques.
+
+   o  Requiring password reentry before issuing OAuth tokens.
+
+4.15.  Automatic Processing of Repeat Authorizations
+
+   Servers may wish to automatically process authorization requests
+   (Section 2.2) from clients that have been previously authorized by
+   the resource owner.  When the resource owner is redirected to the
+   server to grant access, the server detects that the resource owner
+   has already granted access to that particular client.  Instead of
+   prompting the resource owner for approval, the server automatically
+   redirects the resource owner back to the client.
+
+   If the client credentials are compromised, automatic processing
+   creates additional security risks.  An attacker can use the stolen
+   client credentials to redirect the resource owner to the server with
+   an authorization request.  The server will then grant access to the
+   resource owner's data without the resource owner's explicit approval,
+   or even awareness of an attack.  If no automatic approval is
+   implemented, an attacker must use social engineering to convince the
+   resource owner to approve access.
+
+   Servers can mitigate the risks associated with automatic processing
+   by limiting the scope of token credentials obtained through automated
+   approvals.  Tokens credentials obtained through explicit resource
+   owner consent can remain unaffected.  Clients can mitigate the risks
+   associated with automatic processing by protecting their client
+   credentials.

+
+   This specification includes the following changes made to the
+   original community document [OAuthCore1.0_RevisionA] in order to
+   correct mistakes and omissions identified since the document was
+   originally published at <http://oauth.net>.
+
+   o  Changed using TLS/SSL when sending or requesting plain text
+      credentials from SHOULD to MUST.  This change affects any use of
+      the "PLAINTEXT" signature method, as well as requesting temporary
+      credentials (Section 2.1) and obtaining token credentials
+      (Section 2.3).
+
+   o  Adjusted nonce language to indicate it is unique per token/
+      timestamp/client combination.
+
+   o  Removed the requirement for timestamps to be equal to or greater
+      than the timestamp used in the previous request.
+
+   o  Changed the nonce and timestamp parameters to OPTIONAL when using
+      the "PLAINTEXT" signature method.
+
+   o  Extended signature base string coverage that includes
+      "application/x-www-form-urlencoded" entity-body parameters when
+      the HTTP method used is other than "POST" and URI query parameters
+      when the HTTP method used is other than "GET".
+
+   o  Incorporated corrections to the instructions in each signature
+      method to encode the signature value before inserting it into the
+      "oauth_signature" parameter, removing errors that would have
+      caused double-encoded values.
+
+   o  Allowed omitting the "oauth_token" parameter when empty.
+
+   o  Permitted sending requests for temporary credentials with an empty
+      "oauth_token" parameter.
+
+   o  Removed the restrictions from defining additional "oauth_"
+      parameters.

+
+## 1.0.0
+
+_Released: 2015-08-19_
+
+* We are running code-quality builds through Scrutinizer, and we are running unit test builds on the new Travis CI container-based infrastructure.
+* Cleaned up code, as recommended by Scrutinizer.
+* Documentation updates.
+
+## 1.0.0-beta2
+
+_Released: 2015-08-12_

+* Removed newline characters from MAC Authorization header.
+* Documentation updates, notably:
+  - Moved list of providers to `README.PROVIDERS.md`.
+  - Moved provider creation notes to `README.PROVIDER-GUIDE.md`.
+
+## 1.0.0-alpha1
+
+_Released: 2015-06-25_
+
+This release contains numerous BC breaks from the 0.x series. Please note these breaks and refer to the [upgrade guide](GUIDE-UPGRADING.md).
+
+* BREAK: Requires PHP 5.5.0 and greater.
+* BREAK: All providers have been moved to separate repositories, one for each provider.
+* BREAK: All `public` properties have been set as `protected` or `private` and getters/setters have been introduced for access to these properties.
+* BREAK: The `Provider\ProviderInterface` has been removed. Please extend from and override `Provider\AbstractProvider`.
+* BREAK: The `Entity\User` has been removed. Providers should implement the `Provider\UserInterface` and provide user functionality instead of expecting it in this base library.
+* BREAK: The `Grant\GrantInterface` has been removed. Providers needing to provide a new grant type should extend from and override `Grant\AbstractGrant`.
+* A generic `Provider\StandardProvider` has been introduced, which may be used as a client to integrate with most OAuth 2.0 compatible servers.
+* A `Grant\GrantFactory` has been introduced as a means to register and retrieve singleton grants from a registry.
+* Introduced traits for bearer and MAC authorization (`Tool\BearerAuthorizationTrait` and `Tool\MacAuthorizationTrait`), which providers may use to enable these header authorization types.

+# OAuth 2.0 Client
+
+## Provider Guide
+
+New providers may be created by copying the layout of an existing package. See
+the [list of providers](docs/providers/thirdparty.md) for good examples.
+
+When choosing a name for your package, please don’t use the `league` vendor
+prefix, as this implies that it is officially supported. You should use your own
+username as the vendor prefix, and prepend `oauth2-` to the package name to make
+it clear that your package works with OAuth2 Client. For example, if your GitHub
+username was "santa," and you were implementing the "giftpay" OAuth2 library, a
+good name for your composer package would be `santa/oauth2-giftpay`.
+
+### Implementing your own provider
+
+If you are working with an oauth2 service not supported out-of-the-box or by an
+existing package, it is quite simple to implement your own. Simply extend
+[`League\OAuth2\Client\Provider\AbstractProvider`](src/Provider/AbstractProvider.php)
+and implement the required abstract methods:
+
+```php
+abstract public function getBaseAuthorizationUrl();
+abstract public function getBaseAccessTokenUrl(array $params);
+abstract public function getResourceOwnerDetailsUrl(AccessToken $token);
+abstract protected function getDefaultScopes();
+abstract protected function checkResponse(ResponseInterface $response, $data);
+abstract protected function createResourceOwner(array $response, AccessToken $token);
+```
+
+Each of these abstract methods contain a docblock defining their expectations
+and typical behavior. Once you have extended this class, you can simply follow
+the [usage example in the README](README.md#usage) using your new `Provider`.
+
+If you wish to use the `Provider` to make authenticated requests to the
+service, you will also need to define how you provide the token to the
+service. If this is done via headers, you should override this method:
+
+```php
+protected function getAuthorizationHeaders($token = null);
+```
+
+This package comes with a trait for implementing `Bearer` authorization.
+To use this, you just need to include the trait in your `Provider` class:
+
+```php
+<?php
+class SomeProvider extends AbstractProvider
+{
+    use League\OAuth2\Client\Tool\BearerAuthorizationTrait;
+
+    /** ... **/
+}
+```
+
+
+### Resource owner identifiers in access token responses
+
+In services where the resource owner is a person, the resource owner is sometimes
+referred to as an end-user.
+
+We have decided to abstract away as much of the resource owner details as possible,
+since these are not part of the OAuth 2.0 specification and are very specific to each
+service provider. This provides greater flexibility to each provider, allowing
+them to handle the implementation details for resource owners.
+
+The `AbstractProvider` does not specify an access token resource owner identifier. It is
+the responsibility of the provider class to set the `ACCESS_TOKEN_RESOURCE_OWNER_ID` constant
+to the string value of the key used in the access token response to identify the
+resource owner.
+
+```php
+/**
+ * @var string Key used in the access token response to identify the resource owner.
+ */
+const ACCESS_TOKEN_RESOURCE_OWNER_ID = null;
+```
+
+Once this is set on your provider, when calling `AbstractProvider::getAccessToken()`,
+the `AccessToken` returned will have its `$resourceOwnerId` property set, which you may
+retrieve by calling `AccessToken::getResourceOwnerId()`.
+
+The next step is to implement the `AbstractProvider::createResourceOwner()` method. This
+method accepts as parameters a response array and an `AccessToken`. You may use
+this information in order to request resource owner details from your service and
+construct and return an object that implements
+[`League\OAuth2\Client\Provider\ResourceOwnerInterface`](src/Provider/ResourceOwnerInterface.php).
+This object is returned when calling `AbstractProvider::getResourceOwner()`.
+
+### Make your gateway official
+
+If you want to transfer your provider to the `thephpleague` GitHub organization
+and add it to the list of officially supported providers, please open a pull
+request on the thephpleague/oauth2-client package. Before new providers will be
+accepted, they must have 100% unit test code coverage, and follow the
+conventions and code style used in other OAuth2 Client providers.

+
+---
+
+We are all used to seeing those "Connect with Facebook/Google/etc." buttons around the internet, and social network integration is an important feature of most web applications these days. Many of these sites use an authentication and authorization standard called OAuth 2.0 ([RFC 6749](http://tools.ietf.org/html/rfc6749)).
+
+This OAuth 2.0 client library will work with any OAuth provider that conforms to the OAuth 2.0 standard. Out-of-the-box, we provide a `GenericProvider` that may be used to connect to any service provider that uses [Bearer tokens](http://tools.ietf.org/html/rfc6750) (see example below).
+
+Many service providers provide additional functionality above and beyond the OAuth 2.0 standard. For this reason, this library may be easily extended and wrapped to support this additional behavior. We provide links to [all known provider clients extending this library](docs/providers/thirdparty.md) (i.e. Facebook, GitHub, Google, Instagram, LinkedIn, etc.). If your provider isn't in the list, feel free to add it.
+
+This package is compliant with [PSR-1][], [PSR-2][], [PSR-4][], and [PSR-7][]. If you notice compliance oversights, please send a patch via pull request. If you're interesting in contributing to this library, please take a look at our [contributing guidelines](CONTRIBUTING.md).
+
+## Requirements
+
+The following versions of PHP are supported.
+
+* PHP 5.6
+* PHP 7.0
+* PHP 7.1
+* PHP 7.2
+* HHVM
+
+## Providers
+
+A list of official PHP League providers, as well as third-party providers, may be found in the [providers list README](docs/providers/thirdparty.md).
+
+To build your own provider, please refer to the [provider guide README](README.PROVIDER-GUIDE.md).
+
+## Usage
+
+**In most cases, you'll want to use a specific provider client library rather than this base library.**
+
+Take a look at [providers list README](docs/providers/thirdparty.md) to see a list of provider client libraries.
+
+If using Composer to require a specific provider client library, you **do not need to also require this library**. Composer will handle the dependencies for you.
+
+### Authorization Code Grant
+
+The following example uses the out-of-the-box `GenericProvider` provided by this library. If you're looking for a specific provider (i.e. Facebook, Google, GitHub, etc.), take a look at our [list of provider client libraries](docs/providers/thirdparty.md). **HINT: You're probably looking for a specific provider.**
+
+The authorization code grant type is the most common grant type used when authenticating users with a third-party service. This grant type utilizes a client (this library), a server (the service provider), and a resource owner (the user with credentials to a protected—or owned—resource) to request access to resources owned by the user. This is often referred to as _3-legged OAuth_, since there are three parties involved.
+
+The following example illustrates this using [Brent Shaffer's](https://github.com/bshaffer) demo OAuth 2.0 application named **Lock'd In**. When running this code, you will be redirected to Lock'd In, where you'll be prompted to authorize the client to make requests to a resource on your behalf.
+
+Now, you don't really have an account on Lock'd In, but for the sake of this example, imagine that you are already logged in on Lock'd In when you are redirected there.
+
+```php
+$provider = new \League\OAuth2\Client\Provider\GenericProvider([
+    'clientId'                => 'demoapp',    // The client ID assigned to you by the provider
+    'clientSecret'            => 'demopass',   // The client password assigned to you by the provider
+    'redirectUri'             => 'http://example.com/your-redirect-url/',
+    'urlAuthorize'            => 'http://brentertainment.com/oauth2/lockdin/authorize',
+    'urlAccessToken'          => 'http://brentertainment.com/oauth2/lockdin/token',
+    'urlResourceOwnerDetails' => 'http://brentertainment.com/oauth2/lockdin/resource'
+]);
+
+// If we don't have an authorization code then get one
+if (!isset($_GET['code'])) {
+
+    // Fetch the authorization URL from the provider; this returns the
+    // urlAuthorize option and generates and applies any necessary parameters
+    // (e.g. state).
+    $authorizationUrl = $provider->getAuthorizationUrl();
+
+    // Get the state generated for you and store it to the session.
+    $_SESSION['oauth2state'] = $provider->getState();
+
+    // Redirect the user to the authorization URL.
+    header('Location: ' . $authorizationUrl);
+    exit;
+
+// Check given state against previously stored one to mitigate CSRF attack
+} elseif (empty($_GET['state']) || (isset($_SESSION['oauth2state']) && $_GET['state'] !== $_SESSION['oauth2state'])) {
+
+    if (isset($_SESSION['oauth2state'])) {
+        unset($_SESSION['oauth2state']);
+    }
+    
+    exit('Invalid state');
+
+} else {
+
+    try {
+
+        // Try to get an access token using the authorization code grant.
+        $accessToken = $provider->getAccessToken('authorization_code', [
+            'code' => $_GET['code']
+        ]);
+
+        // We have an access token, which we may use in authenticated
+        // requests against the service provider's API.
+        echo 'Access Token: ' . $accessToken->getToken() . "<br>";
+        echo 'Refresh Token: ' . $accessToken->getRefreshToken() . "<br>";
+        echo 'Expired in: ' . $accessToken->getExpires() . "<br>";
+        echo 'Already expired? ' . ($accessToken->hasExpired() ? 'expired' : 'not expired') . "<br>";
+
+        // Using the access token, we may look up details about the
+        // resource owner.
+        $resourceOwner = $provider->getResourceOwner($accessToken);
+
+        var_export($resourceOwner->toArray());
+
+        // The provider provides a way to get an authenticated API request for
+        // the service, using the access token; it returns an object conforming
+        // to Psr\Http\Message\RequestInterface.
+        $request = $provider->getAuthenticatedRequest(
+            'GET',
+            'http://brentertainment.com/oauth2/lockdin/resource',
+            $accessToken
+        );
+
+    } catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {
+
+        // Failed to get the access token or user details.
+        exit($e->getMessage());
+
+    }
+
+}
+```
+
+### Refreshing a Token
+
+Once your application is authorized, you can refresh an expired token using a refresh token rather than going through the entire process of obtaining a brand new token. To do so, simply reuse this refresh token from your data store to request a refresh.
+
+_This example uses [Brent Shaffer's](https://github.com/bshaffer) demo OAuth 2.0 application named **Lock'd In**. See authorization code example above, for more details._
+
+```php
+$provider = new \League\OAuth2\Client\Provider\GenericProvider([
+    'clientId'                => 'demoapp',    // The client ID assigned to you by the provider
+    'clientSecret'            => 'demopass',   // The client password assigned to you by the provider
+    'redirectUri'             => 'http://example.com/your-redirect-url/',
+    'urlAuthorize'            => 'http://brentertainment.com/oauth2/lockdin/authorize',
+    'urlAccessToken'          => 'http://brentertainment.com/oauth2/lockdin/token',
+    'urlResourceOwnerDetails' => 'http://brentertainment.com/oauth2/lockdin/resource'
+]);
+
+$existingAccessToken = getAccessTokenFromYourDataStore();
+
+if ($existingAccessToken->hasExpired()) {
+    $newAccessToken = $provider->getAccessToken('refresh_token', [
+        'refresh_token' => $existingAccessToken->getRefreshToken()
+    ]);
+
+    // Purge old access token and store new access token to your data store.
+}
+```
+
+### Resource Owner Password Credentials Grant
+
+Some service providers allow you to skip the authorization code step to exchange a user's credentials (username and password) for an access token. This is referred to as the "resource owner password credentials" grant type.
+
+According to [section 1.3.3](http://tools.ietf.org/html/rfc6749#section-1.3.3) of the OAuth 2.0 standard (emphasis added):
+
+> The credentials **should only be used when there is a high degree of trust**
+> between the resource owner and the client (e.g., the client is part of the
+> device operating system or a highly privileged application), and when other
+> authorization grant types are not available (such as an authorization code).
+
+**We do not advise using this grant type if the service provider supports the authorization code grant type (see above), as this reinforces the [password anti-pattern](https://agentile.com/the-password-anti-pattern) by allowing users to think it's okay to trust third-party applications with their usernames and passwords.**
+
+That said, there are use-cases where the resource owner password credentials grant is acceptable and useful. Here's an example using it with [Brent Shaffer's](https://github.com/bshaffer) demo OAuth 2.0 application named **Lock'd In**. See authorization code example above, for more details about the Lock'd In demo application.
+
+``` php
+$provider = new \League\OAuth2\Client\Provider\GenericProvider([
+    'clientId'                => 'demoapp',    // The client ID assigned to you by the provider
+    'clientSecret'            => 'demopass',   // The client password assigned to you by the provider
+    'redirectUri'             => 'http://example.com/your-redirect-url/',
+    'urlAuthorize'            => 'http://brentertainment.com/oauth2/lockdin/authorize',
+    'urlAccessToken'          => 'http://brentertainment.com/oauth2/lockdin/token',
+    'urlResourceOwnerDetails' => 'http://brentertainment.com/oauth2/lockdin/resource'
+]);
+
+try {
+
+    // Try to get an access token using the resource owner password credentials grant.
+    $accessToken = $provider->getAccessToken('password', [
+        'username' => 'demouser',
+        'password' => 'testpass'
+    ]);
+
+} catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {
+
+    // Failed to get the access token
+    exit($e->getMessage());
+
+}
+```
+
+### Client Credentials Grant
+
+When your application is acting on its own behalf to access resources it controls/owns in a service provider, it may use the client credentials grant type. This is best used when the credentials for your application are stored privately and never exposed (e.g. through the web browser, etc.) to end-users. This grant type functions similarly to the resource owner password credentials grant type, but it does not request a user's username or password. It uses only the client ID and secret issued to your client by the service provider.
+
+Unlike earlier examples, the following does not work against a functioning demo service provider. It is provided for the sake of example only.
+
+``` php
+// Note: the GenericProvider requires the `urlAuthorize` option, even though
+// it's not used in the OAuth 2.0 client credentials grant type.
+
+$provider = new \League\OAuth2\Client\Provider\GenericProvider([
+    'clientId'                => 'XXXXXX',    // The client ID assigned to you by the provider
+    'clientSecret'            => 'XXXXXX',    // The client password assigned to you by the provider
+    'redirectUri'             => 'http://my.example.com/your-redirect-url/',
+    'urlAuthorize'            => 'http://service.example.com/authorize',
+    'urlAccessToken'          => 'http://service.example.com/token',
+    'urlResourceOwnerDetails' => 'http://service.example.com/resource'
+]);
+
+try {
+
+    // Try to get an access token using the client credentials grant.
+    $accessToken = $provider->getAccessToken('client_credentials');
+
+} catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {
+
+    // Failed to get the access token
+    exit($e->getMessage());
+
+}
+```
+
+### Using a proxy
+
+It is possible to use a proxy to debug HTTP calls made to a provider. All you need to do is set the `proxy` and `verify` options when creating your Provider instance. Make sure you enable SSL proxying in your proxy.
+
+``` php
+$provider = new \League\OAuth2\Client\Provider\GenericProvider([
+    'clientId'                => 'XXXXXX',    // The client ID assigned to you by the provider
+    'clientSecret'            => 'XXXXXX',    // The client password assigned to you by the provider
+    'redirectUri'             => 'http://my.example.com/your-redirect-url/',
+    'urlAuthorize'            => 'http://service.example.com/authorize',
+    'urlAccessToken'          => 'http://service.example.com/token',
+    'urlResourceOwnerDetails' => 'http://service.example.com/resource',
+    'proxy'                   => '192.168.0.1:8888',
+    'verify'                  => false
+]);
+```

+# Contributing
+
+Contributions are **welcome** and will be fully **credited**.
+
+We accept contributions via Pull Requests on [Github](https://github.com/thephpleague/oauth2-github).
+
+
+## Pull Requests
+
+- **[PSR-2 Coding Standard](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md)** - The easiest way to apply the conventions is to install [PHP Code Sniffer](http://pear.php.net/package/PHP_CodeSniffer).
+
+- **Add tests!** - Your patch won't be accepted if it doesn't have tests.
+
+- **Document any change in behaviour** - Make sure the README and any other relevant documentation are kept up-to-date.
+
+- **Consider our release cycle** - We try to follow SemVer. Randomly breaking public APIs is not an option.
+
+- **Create topic branches** - Don't ask us to pull from your master branch.
+
+- **One pull request per feature** - If you want to do more than one thing, send multiple pull requests.
+
+- **Send coherent history** - Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please squash them before submitting.
+
+- **Ensure tests pass!** - Please run the tests (see below) before submitting your pull request, and make sure they pass. We won't accept a patch until all tests pass.
+
+- **Ensure no coding standards violations** - Please run PHP Code Sniffer using the PSR-2 standard (see below) before submitting your pull request. A violation will cause the build to fail, so please make sure there are no violations. We can't accept a patch if the build fails.
+
+
+## Running Tests
+
+``` bash
+$ ./vendor/bin/phpunit
+```
+
+
+## Running PHP Code Sniffer
+
+``` bash
+$ ./vendor/bin/phpcs src --standard=psr2 -sp
+```
+
+**Happy coding**!

+
+This package provides Github OAuth 2.0 support for the PHP League's [OAuth 2.0 Client](https://github.com/thephpleague/oauth2-client).
+
+## Installation
+
+To install, use composer:
+
+```
+composer require league/oauth2-github
+```
+
+## Usage
+
+Usage is the same as The League's OAuth client, using `\League\OAuth2\Client\Provider\Github` as the provider.
+
+### Authorization Code Flow
+
+```php
+$provider = new League\OAuth2\Client\Provider\Github([
+    'clientId'          => '{github-client-id}',
+    'clientSecret'      => '{github-client-secret}',
+    'redirectUri'       => 'https://example.com/callback-url',
+]);
+
+if (!isset($_GET['code'])) {
+
+    // If we don't have an authorization code then get one
+    $authUrl = $provider->getAuthorizationUrl();
+    $_SESSION['oauth2state'] = $provider->getState();
+    header('Location: '.$authUrl);
+    exit;
+
+// Check given state against previously stored one to mitigate CSRF attack
+} elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {
+
+    unset($_SESSION['oauth2state']);
+    exit('Invalid state');
+
+} else {
+
+    // Try to get an access token (using the authorization code grant)
+    $token = $provider->getAccessToken('authorization_code', [
+        'code' => $_GET['code']
+    ]);
+
+    // Optional: Now you have a token you can look up a users profile data
+    try {
+
+        // We got an access token, let's now get the user's details
+        $user = $provider->getResourceOwner($token);
+
+        // Use these details to create a new profile
+        printf('Hello %s!', $user->getNickname());
+
+    } catch (Exception $e) {
+
+        // Failed to get user details
+        exit('Oh dear...');
+    }
+
+    // Use this to interact with an API on the users behalf
+    echo $token->getToken();
+}
+```
+
+### Managing Scopes
+
+When creating your Github authorization URL, you can specify the state and scopes your application may authorize.
+
+```php
+$options = [
+    'state' => 'OPTIONAL_CUSTOM_CONFIGURED_STATE',
+    'scope' => ['user','user:email','repo'] // array or string
+];
+
+$authorizationUrl = $provider->getAuthorizationUrl($options);
+```
+If neither are defined, the provider will utilize internal defaults.
+
+At the time of authoring this documentation, the [following scopes are available](https://developer.github.com/v3/oauth/#scopes).
+
+- user
+- user:email
+- user:follow
+- public_repo
+- repo
+- repo_deployment
+- repo:status
+- delete_repo
+- notifications
+- gist
+- read:repo_hook
+- write:repo_hook
+- admin:repo_hook
+- admin:org_hook
+- read:org
+- write:org
+- admin:org
+- read:public_key
+- write:public_key
+- admin:public_key
+
+## Testing
+
+``` bash
+$ ./vendor/bin/phpunit
+```

+# Contributing
+
+Contributions are **welcome** and will be fully **credited**.
+
+We accept contributions via Pull Requests on [Github](https://github.com/thephpleague/oauth2-google).
+
+
+## Pull Requests
+
+- **[PSR-2 Coding Standard](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md)** - The easiest way to apply the conventions is to install [PHP Code Sniffer](http://pear.php.net/package/PHP_CodeSniffer).
+
+- **Add tests!** - Your patch won't be accepted if it doesn't have tests.
+
+- **Document any change in behaviour** - Make sure the README and any other relevant documentation are kept up-to-date.
+
+- **Consider our release cycle** - We try to follow SemVer. Randomly breaking public APIs is not an option.
+
+- **Create topic branches** - Don't ask us to pull from your master branch.
+
+- **One pull request per feature** - If you want to do more than one thing, send multiple pull requests.
+
+- **Send coherent history** - Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please squash them before submitting.
+
+- **Ensure tests pass!** - Please run the tests (see below) before submitting your pull request, and make sure they pass. We won't accept a patch until all tests pass.
+
+- **Ensure no coding standards violations** - Please run PHP Code Sniffer using the PSR-2 standard (see below) before submitting your pull request. A violation will cause the build to fail, so please make sure there are no violations. We can't accept a patch if the build fails.
+
+
+## Running Tests
+
+``` bash
+$ ./vendor/bin/phpunit
+```
+
+
+## Running PHP Code Sniffer
+
+``` bash
+$ ./vendor/bin/phpcs src --standard=psr2 -sp
+```
+
+**Happy coding**!

+[![Latest Stable Version](https://img.shields.io/packagist/v/league/oauth2-google.svg)](https://packagist.org/packages/league/oauth2-google)
+
+This package provides Google OAuth 2.0 support for the PHP League's [OAuth 2.0 Client](https://github.com/thephpleague/oauth2-client).
+
+This package is compliant with [PSR-1][], [PSR-2][] and [PSR-4][]. If you notice compliance oversights, please send
+a patch via pull request.
+
+[PSR-1]: https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-1-basic-coding-standard.md
+[PSR-2]: https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md
+[PSR-4]: https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-4-autoloader.md
+
+## Requirements
+
+The following versions of PHP are supported.
+
+* PHP 5.6
+* PHP 7.0
+* PHP 7.1
+* HHVM
+
+[Google Sign In](https://developers.google.com/identity/sign-in/web/sign-in) will also need to be set up, which will provide you with the `{google-app-id}` and `{google-app-secret}` required (see [Usage](#usage) below).
+
+If you're using the default [scopes](#scopes) then you'll also need to enable the [Google+ API](https://developers.google.com/+/web/api/rest/) for your project.
+
+## Installation
+
+To install, use composer:
+
+```
+composer require league/oauth2-google
+```
+
+## Usage
+
+### Authorization Code Flow
+
+```php
+$provider = new League\OAuth2\Client\Provider\Google([
+    'clientId'     => '{google-app-id}',
+    'clientSecret' => '{google-app-secret}',
+    'redirectUri'  => 'https://example.com/callback-url',
+    'hostedDomain' => 'example.com',
+]);
+
+if (!empty($_GET['error'])) {
+
+    // Got an error, probably user denied access
+    exit('Got error: ' . htmlspecialchars($_GET['error'], ENT_QUOTES, 'UTF-8'));
+
+} elseif (empty($_GET['code'])) {
+
+    // If we don't have an authorization code then get one
+    $authUrl = $provider->getAuthorizationUrl();
+    $_SESSION['oauth2state'] = $provider->getState();
+    header('Location: ' . $authUrl);
+    exit;
+
+} elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {
+
+    // State is invalid, possible CSRF attack in progress
+    unset($_SESSION['oauth2state']);
+    exit('Invalid state');
+
+} else {
+
+    // Try to get an access token (using the authorization code grant)
+    $token = $provider->getAccessToken('authorization_code', [
+        'code' => $_GET['code']
+    ]);
+
+    // Optional: Now you have a token you can look up a users profile data
+    try {
+
+        // We got an access token, let's now get the owner details
+        $ownerDetails = $provider->getResourceOwner($token);
+
+        // Use these details to create a new profile
+        printf('Hello %s!', $ownerDetails->getFirstName());
+
+    } catch (Exception $e) {
+
+        // Failed to get user details
+        exit('Something went wrong: ' . $e->getMessage());
+
+    }
+
+    // Use this to interact with an API on the users behalf
+    echo $token->getToken();
+
+    // Use this to get a new access token if the old one expires
+    echo $token->getRefreshToken();
+
+    // Number of seconds until the access token will expire, and need refreshing
+    echo $token->getExpires();
+}
+```
+
+### Refreshing a Token
+
+Refresh tokens are only provided to applications which request offline access. You can specify offline access by setting the `accessType` option in your provider:
+
+```php
+$provider = new League\OAuth2\Client\Provider\Google([
+    'clientId'     => '{google-app-id}',
+    'clientSecret' => '{google-app-secret}',
+    'redirectUri'  => 'https://example.com/callback-url',
+    'accessType'   => 'offline',
+]);
+```
+
+It is important to note that the refresh token is only returned on the first request after this it will be `null`. You should securely store the refresh token when it is returned:
+
+```php
+$token = $provider->getAccessToken('authorization_code', [
+    'code' => $code
+]);
+
+// persist the token in a database
+$refreshToken = $token->getRefreshToken();
+```
+
+If you ever need to get a new refresh token you can request one by forcing the approval prompt:
+
+```php
+$authUrl = $provider->getAuthorizationUrl(['approval_prompt' => 'force']);
+```
+
+Now you have everything you need to refresh an access token using a refresh token:
+
+```php
+$provider = new League\OAuth2\Client\Provider\Google([
+    'clientId'     => '{google-app-id}',
+    'clientSecret' => '{google-app-secret}',
+    'redirectUri'  => 'https://example.com/callback-url',
+]);
+
+$grant = new League\OAuth2\Client\Grant\RefreshToken();
+$token = $provider->getAccessToken($grant, ['refresh_token' => $refreshToken]);
+```
+## Resource Owner Attributes
+
+By default the Google plus API is used to load profile information. If you want to use the OpenIDConnect
+user info endpoint to load profile information then add `useOidcMode => true` to your configuration.
+
+The two endpoints provide attributes with different names and structures. The `GoogleUser` class hides
+these differences for the most common attributes.
+
+## Scopes
+
+If needed, you can include an array of scopes when getting the authorization url. Example:
+
+```
+$authorizationUrl = $provider->getAuthorizationUrl([
+    'scope' => [
+        'https://www.googleapis.com/auth/drive',
+    ]
+]);
+header('Location: ' . $authorizationUrl);
+exit;
+```
+
+Note that the default scopes include `email` and `profile`, which require that the [Google+ API](https://developers.google.com/+/web/api/rest/) is enabled for your project.
+
+## Testing
+
+``` bash
+$ ./vendor/bin/phpunit
+```

+  * Fixed a few PHP 7.0 and 7.1 compatibility issues
+
+### 1.21.0 (2016-07-29)
+
+  * Break: Reverted the addition of $context when the ErrorHandler handles regular php errors from 1.20.0 as it was causing issues
+  * Added support for more formats in RotatingFileHandler::setFilenameFormat as long as they have Y, m and d in order

+  * Added $handleOnlyReportedErrors option on ErrorHandler::registerErrorHandler (default true) to allow logging of all errors no matter the error_reporting level

+  * Fixed a few minor bugs
+
+### 1.19.0 (2016-04-12)

+  * Added `Logger->withName` to clone a logger (keeping all handlers) with a new name

+  * Fixed PHP7 compatibility with regard to Exception/Throwable handling in a few places

+### 1.12.0 (2014-12-29)

+  * Fixed multi-threading support in StreamHandler
+  * Fixed empty headers issue when ChromePHPHandler received no records

+# Monolog - Logging for PHP [![Build Status](https://img.shields.io/travis/Seldaek/monolog.svg)](https://travis-ci.org/Seldaek/monolog)
+
+[![Total Downloads](https://img.shields.io/packagist/dt/monolog/monolog.svg)](https://packagist.org/packages/monolog/monolog)
+[![Latest Stable Version](https://img.shields.io/packagist/v/monolog/monolog.svg)](https://packagist.org/packages/monolog/monolog)
+[![Reference Status](https://www.versioneye.com/php/monolog:monolog/reference_badge.svg)](https://www.versioneye.com/php/monolog:monolog/references)
+
+
+Monolog sends your logs to files, sockets, inboxes, databases and various
+web services. See the complete list of handlers below. Special handlers
+allow you to build advanced logging strategies.
+
+This library implements the [PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
+interface that you can type-hint against in your own libraries to keep
+a maximum of interoperability. You can also use it in your applications to
+make sure you can always use another compatible logger at a later time.
+As of 1.11.0 Monolog public APIs will also accept PSR-3 log levels.
+Internally Monolog still uses its own level scheme since it predates PSR-3.
+
+## Installation
+
+Install the latest version with
+
+```bash
+$ composer require monolog/monolog
+```
+
+## Basic Usage
+
+```php
+<?php
+
+use Monolog\Logger;
+use Monolog\Handler\StreamHandler;
+
+// create a log channel
+$log = new Logger('name');
+$log->pushHandler(new StreamHandler('path/to/your.log', Logger::WARNING));
+
+// add records to the log
+$log->addWarning('Foo');
+$log->addError('Bar');
+```

+
+## Installation
+
+Monolog is available on Packagist ([monolog/monolog](http://packagist.org/packages/monolog/monolog))
+and as such installable via [Composer](http://getcomposer.org/).
+
+```bash
+composer require monolog/monolog
+```
+
+If you do not use Composer, you can grab the code from GitHub, and use any
+PSR-0 compatible autoloader (e.g. the [Symfony2 ClassLoader component](https://github.com/symfony/ClassLoader))
+to load Monolog classes.
+
+## Core Concepts
+
+Every `Logger` instance has a channel (name) and a stack of handlers. Whenever
+you add a record to the logger, it traverses the handler stack. Each handler
+decides whether it fully handled the record, and if so, the propagation of the
+record ends there.
+
+This allows for flexible logging setups, for example having a `StreamHandler` at
+the bottom of the stack that will log anything to disk, and on top of that add
+a `MailHandler` that will send emails only when an error message is logged.
+Handlers also have a `$bubble` property which defines whether they block the
+record or not if they handled it. In this example, setting the `MailHandler`'s
+`$bubble` argument to false means that records handled by the `MailHandler` will
+not propagate to the `StreamHandler` anymore.
+
+You can create many `Logger`s, each defining a channel (e.g.: db, request,
+router, ..) and each of them combining various handlers, which can be shared
+or not. The channel is reflected in the logs and allows you to easily see or
+filter records.
+
+Each Handler also has a Formatter, a default one with settings that make sense
+will be created if you don't set one. The formatters normalize and format
+incoming records so that they can be used by the handlers to output useful
+information.
+
+Custom severity levels are not available. Only the eight
+[RFC 5424](http://tools.ietf.org/html/rfc5424) levels (debug, info, notice,
+warning, error, critical, alert, emergency) are present for basic filtering
+purposes, but for sorting and other use cases that would require
+flexibility, you should add Processors to the Logger that can add extra
+information (tags, user ip, ..) to the records before they are handled.
+
+## Log Levels
+
+Monolog supports the logging levels described by [RFC 5424](http://tools.ietf.org/html/rfc5424).
+
+- **DEBUG** (100): Detailed debug information.
+
+- **INFO** (200): Interesting events. Examples: User logs in, SQL logs.
+
+- **NOTICE** (250): Normal but significant events.
+
+- **WARNING** (300): Exceptional occurrences that are not errors. Examples:
+  Use of deprecated APIs, poor use of an API, undesirable things that are not
+  necessarily wrong.
+
+- **ERROR** (400): Runtime errors that do not require immediate action but
+  should typically be logged and monitored.
+
+- **CRITICAL** (500): Critical conditions. Example: Application component
+  unavailable, unexpected exception.
+
+- **ALERT** (550): Action must be taken immediately. Example: Entire website
+  down, database unavailable, etc. This should trigger the SMS alerts and wake
+  you up.
+
+- **EMERGENCY** (600): Emergency: system is unusable.
+
+## Configuring a logger
+
+Here is a basic setup to log to a file and to firephp on the DEBUG level:
+
+```php
+<?php
+
+use Monolog\Logger;
+use Monolog\Handler\StreamHandler;
+use Monolog\Handler\FirePHPHandler;
+
+// Create the logger
+$logger = new Logger('my_logger');
+// Now add some handlers
+$logger->pushHandler(new StreamHandler(__DIR__.'/my_app.log', Logger::DEBUG));
+$logger->pushHandler(new FirePHPHandler());
+
+// You can now use your logger
+$logger->addInfo('My logger is now ready');
+```
+
+Let's explain it. The first step is to create the logger instance which will
+be used in your code. The argument is a channel name, which is useful when
+you use several loggers (see below for more details about it).
+
+The logger itself does not know how to handle a record. It delegates it to
+some handlers. The code above registers two handlers in the stack to allow
+handling records in two different ways.
+
+Note that the FirePHPHandler is called first as it is added on top of the
+stack. This allows you to temporarily add a logger with bubbling disabled if
+you want to override other configured loggers.
+
+> If you use Monolog standalone and are looking for an easy way to
+> configure many handlers, the [theorchard/monolog-cascade](https://github.com/theorchard/monolog-cascade)
+> can help you build complex logging configs via PHP arrays, yaml or json configs.
+
+## Adding extra data in the records
+
+Monolog provides two different ways to add extra informations along the simple
+textual message.
+
+### Using the logging context
+
+The first way is the context, allowing to pass an array of data along the
+record:
+
+```php
+<?php
+
+$logger->addInfo('Adding a new user', array('username' => 'Seldaek'));
+```
+
+Simple handlers (like the StreamHandler for instance) will simply format
+the array to a string but richer handlers can take advantage of the context
+(FirePHP is able to display arrays in pretty way for instance).
+
+### Using processors
+
+The second way is to add extra data for all records by using a processor.
+Processors can be any callable. They will get the record as parameter and
+must return it after having eventually changed the `extra` part of it. Let's
+write a processor adding some dummy data in the record:
+
+```php
+<?php
+
+$logger->pushProcessor(function ($record) {
+    $record['extra']['dummy'] = 'Hello world!';
+
+    return $record;
+});
+```
+
+Monolog provides some built-in processors that can be used in your project.
+Look at the [dedicated chapter](https://github.com/Seldaek/monolog/blob/master/doc/02-handlers-formatters-processors.md#processors) for the list.
+
+> Tip: processors can also be registered on a specific handler instead of
+  the logger to apply only for this handler.
+
+## Leveraging channels
+
+Channels are a great way to identify to which part of the application a record
+is related. This is useful in big applications (and is leveraged by
+MonologBundle in Symfony2).
+
+Picture two loggers sharing a handler that writes to a single log file.
+Channels would allow you to identify the logger that issued every record.
+You can easily grep through the log files filtering this or that channel.
+
+```php
+<?php
+
+use Monolog\Logger;
+use Monolog\Handler\StreamHandler;
+use Monolog\Handler\FirePHPHandler;
+
+// Create some handlers
+$stream = new StreamHandler(__DIR__.'/my_app.log', Logger::DEBUG);
+$firephp = new FirePHPHandler();
+
+// Create the main logger of the app
+$logger = new Logger('my_logger');
+$logger->pushHandler($stream);
+$logger->pushHandler($firephp);
+
+// Create a logger for the security-related stuff with a different channel
+$securityLogger = new Logger('security');
+$securityLogger->pushHandler($stream);
+$securityLogger->pushHandler($firephp);
+
+// Or clone the first one to only change the channel
+$securityLogger = $logger->withName('security');
+```
+
+## Customizing the log format
+
+In Monolog it's easy to customize the format of the logs written into files,
+sockets, mails, databases and other handlers. Most of the handlers use the
+
+```php
+$record['formatted']
+```
+
+value to be automatically put into the log device. This value depends on the
+formatter settings. You can choose between predefined formatter classes or
+write your own (e.g. a multiline text file for human-readable output).
+
+To configure a predefined formatter class, just set it as the handler's field:
+
+```php
+// the default date format is "Y-m-d H:i:s"
+$dateFormat = "Y n j, g:i a";
+// the default output format is "[%datetime%] %channel%.%level_name%: %message% %context% %extra%\n"
+$output = "%datetime% > %level_name% > %message% %context% %extra%\n";
+// finally, create a formatter
+$formatter = new LineFormatter($output, $dateFormat);
+
+// Create a handler
+$stream = new StreamHandler(__DIR__.'/my_app.log', Logger::DEBUG);
+$stream->setFormatter($formatter);
+// bind it to a logger object
+$securityLogger = new Logger('security');
+$securityLogger->pushHandler($stream);
+```
+
+You may also reuse the same formatter between multiple handlers and share those
+handlers between multiple loggers.

+
+### Wrappers / Special Handlers
+
+- _FingersCrossedHandler_: A very interesting wrapper. It takes a logger as
+  parameter and will accumulate log records of all levels until a record
+  exceeds the defined severity level. At which point it delivers all records,
+  including those of lower severity, to the handler it wraps. This means that
+  until an error actually happens you will not see anything in your logs, but
+  when it happens you will have the full information, including debug and info
+  records. This provides you with all the information you need, but only when
+  you need it.
+- _DeduplicationHandler_: Useful if you are sending notifications or emails
+  when critical errors occur. It takes a logger as parameter and will
+  accumulate log records of all levels until the end of the request (or
+  `flush()` is called). At that point it delivers all records to the handler
+  it wraps, but only if the records are unique over a given time period
+  (60seconds by default). If the records are duplicates they are simply
+  discarded. The main use of this is in case of critical failure like if your
+  database is unreachable for example all your requests will fail and that
+  can result in a lot of notifications being sent. Adding this handler reduces
+  the amount of notifications to a manageable level.
+- _WhatFailureGroupHandler_: This handler extends the _GroupHandler_ ignoring
+   exceptions raised by each child handler. This allows you to ignore issues
+   where a remote tcp connection may have died but you do not want your entire
+   application to crash and may wish to continue to log to other handlers.
+- _BufferHandler_: This handler will buffer all the log records it receives
+  until `close()` is called at which point it will call `handleBatch()` on the
+  handler it wraps with all the log messages at once. This is very useful to
+  send an email with all records at once for example instead of having one mail
+  for every log record.
+- _GroupHandler_: This handler groups other handlers. Every record received is
+  sent to all the handlers it is configured with.
+- _FilterHandler_: This handler only lets records of the given levels through
+   to the wrapped handler.
+- _SamplingHandler_: Wraps around another handler and lets you sample records
+   if you only want to store some of them.
+- _NullHandler_: Any record it can handle will be thrown away. This can be used
+  to put on top of an existing handler stack to disable it temporarily.
+- _PsrHandler_: Can be used to forward log records to an existing PSR-3 logger
+- _TestHandler_: Used for testing, it records everything that is sent to it and
+  has accessors to read out the information.
+- _HandlerWrapper_: A simple handler wrapper you can inherit from to create
+ your own wrappers easily.
+
+## Formatters
+
+- _LineFormatter_: Formats a log record into a one-line string.
+- _HtmlFormatter_: Used to format log records into a human readable html table, mainly suitable for emails.
+- _NormalizerFormatter_: Normalizes objects/resources down to strings so a record can easily be serialized/encoded.
+- _ScalarFormatter_: Used to format log records into an associative array of scalar values.
+- _JsonFormatter_: Encodes a log record into json.
+- _WildfireFormatter_: Used to format log records into the Wildfire/FirePHP protocol, only useful for the FirePHPHandler.
+- _ChromePHPFormatter_: Used to format log records into the ChromePHP format, only useful for the ChromePHPHandler.
+- _GelfMessageFormatter_: Used to format log records into Gelf message instances, only useful for the GelfHandler.
+- _LogstashFormatter_: Used to format log records into [logstash](http://logstash.net/) event json, useful for any handler listed under inputs [here](http://logstash.net/docs/latest).
+- _ElasticaFormatter_: Used to format log records into an Elastica\Document object, only useful for the ElasticSearchHandler.
+- _LogglyFormatter_: Used to format log records into Loggly messages, only useful for the LogglyHandler.
+- _FlowdockFormatter_: Used to format log records into Flowdock messages, only useful for the FlowdockHandler.
+- _MongoDBFormatter_: Converts \DateTime instances to \MongoDate and objects recursively to arrays, only useful with the MongoDBHandler.
+
+## Processors
+
+- _PsrLogMessageProcessor_: Processes a log record's message according to PSR-3 rules, replacing `{foo}` with the value from `$context['foo']`.
+- _IntrospectionProcessor_: Adds the line/file/class/method from which the log call originated.
+- _WebProcessor_: Adds the current request URI, request method and client IP to a log record.
+- _MemoryUsageProcessor_: Adds the current memory usage to a log record.
+- _MemoryPeakUsageProcessor_: Adds the peak memory usage to a log record.
+- _ProcessIdProcessor_: Adds the process id to a log record.
+- _UidProcessor_: Adds a unique identifier to a log record.
+- _GitProcessor_: Adds the current git branch and commit to a log record.
+- _TagProcessor_: Adds an array of predefined tags to a log record.

+# Utilities
+
+- _Registry_: The `Monolog\Registry` class lets you configure global loggers that you
+  can then statically access from anywhere. It is not really a best practice but can

+# Extending Monolog
+
+Monolog is fully extensible, allowing you to adapt your logger to your needs.
+
+## Writing your own handler
+
+Monolog provides many built-in handlers. But if the one you need does not
+exist, you can write it and use it in your logger. The only requirement is
+to implement `Monolog\Handler\HandlerInterface`.
+
+Let's write a PDOHandler to log records to a database. We will extend the
+abstract class provided by Monolog to keep things DRY.
+
+```php
+<?php
+
+use Monolog\Logger;
+use Monolog\Handler\AbstractProcessingHandler;
+
+class PDOHandler extends AbstractProcessingHandler
+{
+    private $initialized = false;
+    private $pdo;
+    private $statement;
+
+    public function __construct(PDO $pdo, $level = Logger::DEBUG, $bubble = true)
+    {
+        $this->pdo = $pdo;
+        parent::__construct($level, $bubble);
+    }
+
+    protected function write(array $record)
+    {
+        if (!$this->initialized) {
+            $this->initialize();
+        }
+
+        $this->statement->execute(array(
+            'channel' => $record['channel'],
+            'level' => $record['level'],
+            'message' => $record['formatted'],
+            'time' => $record['datetime']->format('U'),
+        ));
+    }
+
+    private function initialize()
+    {
+        $this->pdo->exec(
+            'CREATE TABLE IF NOT EXISTS monolog '
+            .'(channel VARCHAR(255), level INTEGER, message LONGTEXT, time INTEGER UNSIGNED)'
+        );
+        $this->statement = $this->pdo->prepare(
+            'INSERT INTO monolog (channel, level, message, time) VALUES (:channel, :level, :message, :time)'
+        );
+
+        $this->initialized = true;
+    }
+}
+```
+
+You can now use this handler in your logger:
+
+```php
+<?php
+
+$logger->pushHandler(new PDOHandler(new PDO('sqlite:logs.sqlite')));
+
+// You can now use your logger
+$logger->addInfo('My logger is now ready');
+```
+
+The `Monolog\Handler\AbstractProcessingHandler` class provides most of the
+logic needed for the handler, including the use of processors and the formatting
+of the record (which is why we use ``$record['formatted']`` instead of ``$record['message']``).

+Sockets Handler
+===============
+
+This handler allows you to write your logs to sockets using [fsockopen](http://php.net/fsockopen)
+or [pfsockopen](http://php.net/pfsockopen).
+
+Persistent sockets are mainly useful in web environments where you gain some performance not closing/opening
+the connections between requests.
+
+You can use a `unix://` prefix to access unix sockets and `udp://` to open UDP sockets instead of the default TCP.
+
+Basic Example
+-------------
+
+```php
+<?php
+
+use Monolog\Logger;
+use Monolog\Handler\SocketHandler;
+
+// Create the logger
+$logger = new Logger('my_logger');
+
+// Create the handler
+$handler = new SocketHandler('unix:///var/log/httpd_app_log.socket');
+$handler->setPersistent(true);
+
+// Now add the handler
+$logger->pushHandler($handler, Logger::DEBUG);
+
+// You can now use your logger
+$logger->addInfo('My logger is now ready');
+
+```
+
+In this example, using syslog-ng, you should see the log on the log server:
+
+    cweb1 [2012-02-26 00:12:03] my_logger.INFO: My logger is now ready [] []

+ * Simple handler wrapper that deduplicates log records across multiple requests

+ * request (or when flush() is called), all those above $deduplicationLevel are checked
+ * against the existing stored logs. If they match and the timestamps in the stored log is
+ * not older than $time seconds, the new log record is discarded. If no log record is new, the
+ * whole data set is discarded.
+ *
+ * This is mainly useful in combination with Mail handlers or things like Slack or HipChat handlers
+ * that send messages to people, to avoid spamming with the same message over and over in case of
+ * a major component failure like a database server being down which makes all requests fail in the

+
+## How?
+
+Install with Composer:
+
+```json
+composer require myclabs/deep-copy
+```
+
+Use simply:
+
+```php
+use DeepCopy\DeepCopy;
+
+$copier = new DeepCopy();
+$myCopy = $copier->copy($myObject);
+```
+
+
+## Why?
+
+- How do you create copies of your objects?
+
+```php
+$myCopy = clone $myObject;
+```
+
+- How do you create **deep** copies of your objects (i.e. copying also all the objects referenced in the properties)?
+
+You use [`__clone()`](http://www.php.net/manual/en/language.oop5.cloning.php#object.clone) and implement the behavior
+yourself.
+
+- But how do you handle **cycles** in the association graph?
+
+Now you're in for a big mess :(
+
+![association graph](doc/graph.png)
+
+
+### Using simply `clone`
+
+![Using clone](doc/clone.png)
+
+
+### Overridding `__clone()`
+
+![Overridding __clone](doc/deep-clone.png)
+
+
+### With `DeepCopy`
+
+![With DeepCopy](doc/deep-copy.png)
+
+
+## How it works
+
+DeepCopy recursively traverses all the object's properties and clones them. To avoid cloning the same object twice it
+keeps a hash map of all instances and thus preserves the object graph.
+
+To use it:
+
+```php
+use function DeepCopy\deep_copy;
+
+$copy = deep_copy($var);
+```
+
+Alternatively, you can create your own `DeepCopy` instance to configure it differently for example:
+
+```php
+use DeepCopy\DeepCopy;
+
+$copier = new DeepCopy(true);
+
+$copy = $copier->copy($var);
+```
+
+You may want to roll your own deep copy function:
+
+```php
+namespace Acme;
+
+use DeepCopy\DeepCopy;
+
+function deep_copy($var)
+{
+    static $copier = null;
+    
+    if (null === $copier) {
+        $copier = new DeepCopy(true);
+    }
+    
+    return $copier->copy($var);
+}
+```
+
+
+## Going further
+
+You can add filters to customize the copy process.
+
+The method to add a filter is `DeepCopy\DeepCopy::addFilter($filter, $matcher)`,
+with `$filter` implementing `DeepCopy\Filter\Filter`
+and `$matcher` implementing `DeepCopy\Matcher\Matcher`.
+
+We provide some generic filters and matchers.
+
+
+### Matchers
+
+  - `DeepCopy\Matcher` applies on a object attribute.
+  - `DeepCopy\TypeMatcher` applies on any element found in graph, including array elements.
+
+
+#### Property name
+
+The `PropertyNameMatcher` will match a property by its name:
+
+```php
+use DeepCopy\Matcher\PropertyNameMatcher;
+
+// Will apply a filter to any property of any objects named "id"
+$matcher = new PropertyNameMatcher('id');
+```
+
+
+#### Specific property
+
+The `PropertyMatcher` will match a specific property of a specific class:
+
+```php
+use DeepCopy\Matcher\PropertyMatcher;
+
+// Will apply a filter to the property "id" of any objects of the class "MyClass"
+$matcher = new PropertyMatcher('MyClass', 'id');
+```
+
+
+#### Type
+
+The `TypeMatcher` will match any element by its type (instance of a class or any value that could be parameter of
+[gettype()](http://php.net/manual/en/function.gettype.php) function):
+
+```php
+use DeepCopy\TypeMatcher\TypeMatcher;
+
+// Will apply a filter to any object that is an instance of Doctrine\Common\Collections\Collection
+$matcher = new TypeMatcher('Doctrine\Common\Collections\Collection');
+```
+
+
+### Filters
+
+- `DeepCopy\Filter` applies a transformation to the object attribute matched by `DeepCopy\Matcher`
+- `DeepCopy\TypeFilter` applies a transformation to any element matched by `DeepCopy\TypeMatcher`
+
+
+#### `SetNullFilter` (filter)
+
+Let's say for example that you are copying a database record (or a Doctrine entity), so you want the copy not to have
+any ID:
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\SetNullFilter;
+use DeepCopy\Matcher\PropertyNameMatcher;
+
+$object = MyClass::load(123);
+echo $object->id; // 123
+
+$copier = new DeepCopy();
+$copier->addFilter(new SetNullFilter(), new PropertyNameMatcher('id'));
+
+$copy = $copier->copy($object);
+
+echo $copy->id; // null
+```
+
+
+#### `KeepFilter` (filter)
+
+If you want a property to remain untouched (for example, an association to an object):
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\KeepFilter;
+use DeepCopy\Matcher\PropertyMatcher;
+
+$copier = new DeepCopy();
+$copier->addFilter(new KeepFilter(), new PropertyMatcher('MyClass', 'category'));
+
+$copy = $copier->copy($object);
+// $copy->category has not been touched
+```
+
+
+#### `DoctrineCollectionFilter` (filter)
+
+If you use Doctrine and want to copy an entity, you will need to use the `DoctrineCollectionFilter`:
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\Doctrine\DoctrineCollectionFilter;
+use DeepCopy\Matcher\PropertyTypeMatcher;
+
+$copier = new DeepCopy();
+$copier->addFilter(new DoctrineCollectionFilter(), new PropertyTypeMatcher('Doctrine\Common\Collections\Collection'));
+
+$copy = $copier->copy($object);
+```
+
+
+#### `DoctrineEmptyCollectionFilter` (filter)
+
+If you use Doctrine and want to copy an entity who contains a `Collection` that you want to be reset, you can use the
+`DoctrineEmptyCollectionFilter`
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\Doctrine\DoctrineEmptyCollectionFilter;
+use DeepCopy\Matcher\PropertyMatcher;
+
+$copier = new DeepCopy();
+$copier->addFilter(new DoctrineEmptyCollectionFilter(), new PropertyMatcher('MyClass', 'myProperty'));
+
+$copy = $copier->copy($object);
+
+// $copy->myProperty will return an empty collection
+```
+
+
+#### `DoctrineProxyFilter` (filter)
+
+If you use Doctrine and use cloning on lazy loaded entities, you might encounter errors mentioning missing fields on a
+Doctrine proxy class (...\\\_\_CG\_\_\Proxy).
+You can use the `DoctrineProxyFilter` to load the actual entity behind the Doctrine proxy class.
+**Make sure, though, to put this as one of your very first filters in the filter chain so that the entity is loaded
+before other filters are applied!**
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\Doctrine\DoctrineProxyFilter;
+use DeepCopy\Matcher\Doctrine\DoctrineProxyMatcher;
+
+$copier = new DeepCopy();
+$copier->addFilter(new DoctrineProxyFilter(), new DoctrineProxyMatcher());
+
+$copy = $copier->copy($object);
+
+// $copy should now contain a clone of all entities, including those that were not yet fully loaded.
+```
+
+
+#### `ReplaceFilter` (type filter)
+
+1. If you want to replace the value of a property:
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\ReplaceFilter;
+use DeepCopy\Matcher\PropertyMatcher;
+
+$copier = new DeepCopy();
+$callback = function ($currentValue) {
+  return $currentValue . ' (copy)'
+};
+$copier->addFilter(new ReplaceFilter($callback), new PropertyMatcher('MyClass', 'title'));
+
+$copy = $copier->copy($object);
+
+// $copy->title will contain the data returned by the callback, e.g. 'The title (copy)'
+```
+
+2. If you want to replace whole element:
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\TypeFilter\ReplaceFilter;
+use DeepCopy\TypeMatcher\TypeMatcher;
+
+$copier = new DeepCopy();
+$callback = function (MyClass $myClass) {
+  return get_class($myClass);
+};
+$copier->addTypeFilter(new ReplaceFilter($callback), new TypeMatcher('MyClass'));
+
+$copy = $copier->copy([new MyClass, 'some string', new MyClass]);
+
+// $copy will contain ['MyClass', 'some string', 'MyClass']
+```
+
+
+The `$callback` parameter of the `ReplaceFilter` constructor accepts any PHP callable.
+
+
+#### `ShallowCopyFilter` (type filter)
+
+Stop *DeepCopy* from recursively copying element, using standard `clone` instead:
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\TypeFilter\ShallowCopyFilter;
+use DeepCopy\TypeMatcher\TypeMatcher;
+use Mockery as m;
+
+$this->deepCopy = new DeepCopy();
+$this->deepCopy->addTypeFilter(
+	new ShallowCopyFilter,
+	new TypeMatcher(m\MockInterface::class)
+);
+
+$myServiceWithMocks = new MyService(m::mock(MyDependency1::class), m::mock(MyDependency2::class));
+// All mocks will be just cloned, not deep copied
+```
+
+
+## Edge cases
+
+The following structures cannot be deep-copied with PHP Reflection. As a result they are shallow cloned and filters are
+not applied. There is two ways for you to handle them:
+
+- Implement your own `__clone()` method
+- Use a filter with a type matcher

+FastRoute - Fast request router for PHP
+=======================================
+
+This library provides a fast implementation of a regular expression based router. [Blog post explaining how the
+implementation works and why it is fast.][blog_post]
+
+Install
+-------
+
+To install with composer:
+
+```sh
+composer require nikic/fast-route
+```
+
+Requires PHP 5.4 or newer.
+
+Usage
+-----
+
+Here's a basic usage example:
+
+```php
+<?php
+
+require '/path/to/vendor/autoload.php';
+
+$dispatcher = FastRoute\simpleDispatcher(function(FastRoute\RouteCollector $r) {
+    $r->addRoute('GET', '/users', 'get_all_users_handler');
+    // {id} must be a number (\d+)
+    $r->addRoute('GET', '/user/{id:\d+}', 'get_user_handler');
+    // The /{title} suffix is optional
+    $r->addRoute('GET', '/articles/{id:\d+}[/{title}]', 'get_article_handler');
+});
+
+// Fetch method and URI from somewhere
+$httpMethod = $_SERVER['REQUEST_METHOD'];
+$uri = $_SERVER['REQUEST_URI'];
+
+// Strip query string (?foo=bar) and decode URI
+if (false !== $pos = strpos($uri, '?')) {
+    $uri = substr($uri, 0, $pos);
+}
+$uri = rawurldecode($uri);
+
+$routeInfo = $dispatcher->dispatch($httpMethod, $uri);
+switch ($routeInfo[0]) {
+    case FastRoute\Dispatcher::NOT_FOUND:
+        // ... 404 Not Found
+        break;
+    case FastRoute\Dispatcher::METHOD_NOT_ALLOWED:
+        $allowedMethods = $routeInfo[1];
+        // ... 405 Method Not Allowed
+        break;
+    case FastRoute\Dispatcher::FOUND:
+        $handler = $routeInfo[1];
+        $vars = $routeInfo[2];
+        // ... call $handler with $vars
+        break;
+}
+```
+
+### Defining routes
+
+The routes are defined by calling the `FastRoute\simpleDispatcher()` function, which accepts
+a callable taking a `FastRoute\RouteCollector` instance. The routes are added by calling
+`addRoute()` on the collector instance:
+
+```php
+$r->addRoute($method, $routePattern, $handler);
+```
+
+The `$method` is an uppercase HTTP method string for which a certain route should match. It
+is possible to specify multiple valid methods using an array:
+
+```php
+// These two calls
+$r->addRoute('GET', '/test', 'handler');
+$r->addRoute('POST', '/test', 'handler');
+// Are equivalent to this one call
+$r->addRoute(['GET', 'POST'], '/test', 'handler');
+```
+
+By default the `$routePattern` uses a syntax where `{foo}` specifies a placeholder with name `foo`
+and matching the regex `[^/]+`. To adjust the pattern the placeholder matches, you can specify
+a custom pattern by writing `{bar:[0-9]+}`. Some examples:
+
+```php
+// Matches /user/42, but not /user/xyz
+$r->addRoute('GET', '/user/{id:\d+}', 'handler');
+
+// Matches /user/foobar, but not /user/foo/bar
+$r->addRoute('GET', '/user/{name}', 'handler');
+
+// Matches /user/foo/bar as well
+$r->addRoute('GET', '/user/{name:.+}', 'handler');
+```
+
+Custom patterns for route placeholders cannot use capturing groups. For example `{lang:(en|de)}`
+is not a valid placeholder, because `()` is a capturing group. Instead you can use either
+`{lang:en|de}` or `{lang:(?:en|de)}`.
+
+Furthermore parts of the route enclosed in `[...]` are considered optional, so that `/foo[bar]`
+will match both `/foo` and `/foobar`. Optional parts are only supported in a trailing position,
+not in the middle of a route.
+
+```php
+// This route
+$r->addRoute('GET', '/user/{id:\d+}[/{name}]', 'handler');
+// Is equivalent to these two routes
+$r->addRoute('GET', '/user/{id:\d+}', 'handler');
+$r->addRoute('GET', '/user/{id:\d+}/{name}', 'handler');
+
+// Multiple nested optional parts are possible as well
+$r->addRoute('GET', '/user[/{id:\d+}[/{name}]]', 'handler');
+
+// This route is NOT valid, because optional parts can only occur at the end
+$r->addRoute('GET', '/user[/{id:\d+}]/{name}', 'handler');
+```
+
+The `$handler` parameter does not necessarily have to be a callback, it could also be a controller
+class name or any other kind of data you wish to associate with the route. FastRoute only tells you
+which handler corresponds to your URI, how you interpret it is up to you.
+
+#### Shorcut methods for common request methods
+
+For the `GET`, `POST`, `PUT`, `PATCH`, `DELETE` and `HEAD` request methods shortcut methods are available. For example:
+
+```php
+$r->get('/get-route', 'get_handler');
+$r->post('/post-route', 'post_handler');
+```
+
+Is equivalent to:
+
+```php
+$r->addRoute('GET', '/get-route', 'get_handler');
+$r->addRoute('POST', '/post-route', 'post_handler');
+```
+
+#### Route Groups
+
+Additionally, you can specify routes inside of a group. All routes defined inside a group will have a common prefix.
+
+For example, defining your routes as:
+
+```php
+$r->addGroup('/admin', function (RouteCollector $r) {
+    $r->addRoute('GET', '/do-something', 'handler');
+    $r->addRoute('GET', '/do-another-thing', 'handler');
+    $r->addRoute('GET', '/do-something-else', 'handler');
+});
+```
+
+Will have the same result as:
+
+ ```php
+$r->addRoute('GET', '/admin/do-something', 'handler');
+$r->addRoute('GET', '/admin/do-another-thing', 'handler');
+$r->addRoute('GET', '/admin/do-something-else', 'handler');
+ ```
+
+Nested groups are also supported, in which case the prefixes of all the nested groups are combined.
+
+### Caching
+
+The reason `simpleDispatcher` accepts a callback for defining the routes is to allow seamless
+caching. By using `cachedDispatcher` instead of `simpleDispatcher` you can cache the generated
+routing data and construct the dispatcher from the cached information:
+
+```php
+<?php
+
+$dispatcher = FastRoute\cachedDispatcher(function(FastRoute\RouteCollector $r) {
+    $r->addRoute('GET', '/user/{name}/{id:[0-9]+}', 'handler0');
+    $r->addRoute('GET', '/user/{id:[0-9]+}', 'handler1');
+    $r->addRoute('GET', '/user/{name}', 'handler2');
+}, [
+    'cacheFile' => __DIR__ . '/route.cache', /* required */
+    'cacheDisabled' => IS_DEBUG_ENABLED,     /* optional, enabled by default */
+]);
+```
+
+The second parameter to the function is an options array, which can be used to specify the cache
+file location, among other things.
+
+### Dispatching a URI
+
+A URI is dispatched by calling the `dispatch()` method of the created dispatcher. This method
+accepts the HTTP method and a URI. Getting those two bits of information (and normalizing them
+appropriately) is your job - this library is not bound to the PHP web SAPIs.
+
+The `dispatch()` method returns an array whose first element contains a status code. It is one
+of `Dispatcher::NOT_FOUND`, `Dispatcher::METHOD_NOT_ALLOWED` and `Dispatcher::FOUND`. For the
+method not allowed status the second array element contains a list of HTTP methods allowed for
+the supplied URI. For example:
+
+    [FastRoute\Dispatcher::METHOD_NOT_ALLOWED, ['GET', 'POST']]
+
+> **NOTE:** The HTTP specification requires that a `405 Method Not Allowed` response include the
+`Allow:` header to detail available methods for the requested resource. Applications using FastRoute
+should use the second array element to add this header when relaying a 405 response.
+
+For the found status the second array element is the handler that was associated with the route
+and the third array element is a dictionary of placeholder names to their values. For example:
+
+    /* Routing against GET /user/nikic/42 */
+
+    [FastRoute\Dispatcher::FOUND, 'handler0', ['name' => 'nikic', 'id' => '42']]
+
+### Overriding the route parser and dispatcher
+
+The routing process makes use of three components: A route parser, a data generator and a
+dispatcher. The three components adhere to the following interfaces:
+
+```php
+<?php
+
+namespace FastRoute;
+
+interface RouteParser {
+    public function parse($route);
+}
+
+interface DataGenerator {
+    public function addRoute($httpMethod, $routeData, $handler);
+    public function getData();
+}
+
+interface Dispatcher {
+    const NOT_FOUND = 0, FOUND = 1, METHOD_NOT_ALLOWED = 2;
+
+    public function dispatch($httpMethod, $uri);
+}
+```
+
+The route parser takes a route pattern string and converts it into an array of route infos, where
+each route info is again an array of it's parts. The structure is best understood using an example:
+
+    /* The route /user/{id:\d+}[/{name}] converts to the following array: */
+    [
+        [
+            '/user/',
+            ['id', '\d+'],
+        ],
+        [
+            '/user/',
+            ['id', '\d+'],
+            '/',
+            ['name', '[^/]+'],
+        ],
+    ]
+
+This array can then be passed to the `addRoute()` method of a data generator. After all routes have
+been added the `getData()` of the generator is invoked, which returns all the routing data required
+by the dispatcher. The format of this data is not further specified - it is tightly coupled to
+the corresponding dispatcher.
+
+The dispatcher accepts the routing data via a constructor and provides a `dispatch()` method, which
+you're already familiar with.
+
+The route parser can be overwritten individually (to make use of some different pattern syntax),
+however the data generator and dispatcher should always be changed as a pair, as the output from
+the former is tightly coupled to the input of the latter. The reason the generator and the
+dispatcher are separate is that only the latter is needed when using caching (as the output of
+the former is what is being cached.)
+
+When using the `simpleDispatcher` / `cachedDispatcher` functions from above the override happens
+through the options array:
+
+```php
+<?php
+
+$dispatcher = FastRoute\simpleDispatcher(function(FastRoute\RouteCollector $r) {
+    /* ... */
+}, [
+    'routeParser' => 'FastRoute\\RouteParser\\Std',
+    'dataGenerator' => 'FastRoute\\DataGenerator\\GroupCountBased',
+    'dispatcher' => 'FastRoute\\Dispatcher\\GroupCountBased',
+]);
+```
+
+The above options array corresponds to the defaults. By replacing `GroupCountBased` by
+`GroupPosBased` you could switch to a different dispatching strategy.
+
+### A Note on HEAD Requests
+
+The HTTP spec requires servers to [support both GET and HEAD methods][2616-511]:
+
+> The methods GET and HEAD MUST be supported by all general-purpose servers
+
+To avoid forcing users to manually register HEAD routes for each resource we fallback to matching an
+available GET route for a given resource. The PHP web SAPI transparently removes the entity body
+from HEAD responses so this behavior has no effect on the vast majority of users.
+
+However, implementers using FastRoute outside the web SAPI environment (e.g. a custom server) MUST
+NOT send entity bodies generated in response to HEAD requests. If you are a non-SAPI user this is
+*your responsibility*; FastRoute has no purview to prevent you from breaking HTTP in such cases.
+
+Finally, note that applications MAY always specify their own HEAD method route for a given
+resource to bypass this behavior entirely.

+The ReflectionDocBlock Component [![Build Status](https://secure.travis-ci.org/phpDocumentor/ReflectionDocBlock.png)](https://travis-ci.org/phpDocumentor/ReflectionDocBlock)
+================================
+
+Introduction
+------------
+
+The ReflectionDocBlock component of phpDocumentor provides a DocBlock parser
+that is 100% compatible with the [PHPDoc standard](http://phpdoc.org/docs/latest).
+
+With this component, a library can provide support for annotations via DocBlocks
+or otherwise retrieve information that is embedded in a DocBlock.
+
+Installation
+------------
+
+```bash
+composer require phpdocumentor/reflection-docblock
+```
+
+Usage
+-----
+
+In order to parse the DocBlock one needs a DocBlockFactory that can be
+instantiated using its `createInstance` factory method like this:
+
+```php
+$factory  = \phpDocumentor\Reflection\DocBlockFactory::createInstance();
+```
+
+Then we can use the `create` method of the factory to interpret the DocBlock. 
+Please note that it is also possible to provide a class that has the 
+`getDocComment()` method, such as an object of type `ReflectionClass`, the
+create method will read that if it exists.
+
+```php
+$docComment = <<<DOCCOMMENT
+/**
+ * This is an example of a summary.
+ *
+ * This is a Description. A Summary and Description are separated by either
+ * two subsequent newlines (thus a whiteline in between as can be seen in this
+ * example), or when the Summary ends with a dot (`.`) and some form of
+ * whitespace.
+ */
+DOCCOMMENT;
+
+$docblock = $factory->create($docComment);
+```
+
+The `create` method will yield an object of type `\phpDocumentor\Reflection\DocBlock`
+whose methods can be queried:
+
+```php
+// Contains the summary for this DocBlock
+$summary = $docblock->getSummary();
+
+// Contains \phpDocumentor\Reflection\DocBlock\Description object
+$description = $docblock->getDescription();
+
+// You can either cast it to string
+$description = (string) $docblock->getDescription();
+
+// Or use the render method to get a string representation of the Description.
+$description = $docblock->getDescription()->render();
+```
+
+> For more examples it would be best to review the scripts in the [`/examples` folder](/examples).

+ * body that can be replaced with a readable output. The replacing is done by passing a Formatter object to the
+ * Description object's `render` method.
+ *
+ * In addition to the above does a Description support two types of escape sequences:
+ *
+ * 1. `{@}` to escape the `@` character to prevent it from being interpreted as part of a tag, i.e. `{{@}link}`
+ * 2. `{}` to escape the `}` character, this can be used if you want to use the `}` character in the description
+ *    of an inline tag.
+ *
+ * If a body consists of multiple lines then this factory will also remove any superfluous whitespace at the beginning
+ * of each line while maintaining any indentation that is used. This will prevent formatting parsers from tripping
+ * over unexpected spaces as can be observed with tag descriptions.

+ * pass the dependencies that you need to construct a tag object.
+ *
+ * > Important: each parameter in addition to the body variable for the `create` method must default to null, otherwise

+TypeResolver and FqsenResolver
+==============================
+
+The specification on types in DocBlocks (PSR-5) describes various keywords and special constructs
+but also how to statically resolve the partial name of a Class into a Fully Qualified Class Name (FQCN).
+
+PSR-5 also introduces an additional way to describe deeper elements than Classes, Interfaces and Traits 
+called the Fully Qualified Structural Element Name (FQSEN). Using this it is possible to refer to methods,
+properties and class constants but also functions and global constants.
+
+This package provides two Resolvers that are capable of 
+
+1. Returning a series of Value Object for given expression while resolving any partial class names, and 
+2. Returning an FQSEN object after resolving any partial Structural Element Names into Fully Qualified Structural 
+   Element names.
+
+## Installing
+
+The easiest way to install this library is with [Composer](https://getcomposer.org) using the following command:
+
+    $ composer require phpdocumentor/type-resolver
+
+## Examples
+
+Ready to dive in and don't want to read through all that text below? Just consult the [examples](examples) folder and
+check which type of action that your want to accomplish.
+
+## On Types and Element Names
+
+This component can be used in one of two ways
+ 
+1. To resolve a Type or
+2. To resolve a Fully Qualified Structural Element Name
+ 
+The big difference between these two is in the number of things it can resolve. 
+
+The TypeResolver can resolve:
+
+- a php primitive or pseudo-primitive such as a string or void (`@var string` or `@return void`).
+- a composite such as an array of string (`@var string[]`).
+- a compound such as a string or integer (`@var string|integer`).
+- an object or interface such as the TypeResolver class (`@var TypeResolver` 
+  or `@var \phpDocumentor\Reflection\TypeResolver`)
+
+  > please note that if you want to pass partial class names that additional steps are necessary, see the 
+  > chapter `Resolving partial classes and FQSENs` for more information.
+
+Where the FqsenResolver can resolve:
+
+- Constant expressions (i.e. `@see \MyNamespace\MY_CONSTANT`)
+- Function expressions (i.e. `@see \MyNamespace\myFunction()`)
+- Class expressions (i.e. `@see \MyNamespace\MyClass`)
+- Interface expressions (i.e. `@see \MyNamespace\MyInterface`)
+- Trait expressions (i.e. `@see \MyNamespace\MyTrait`)
+- Class constant expressions (i.e. `@see \MyNamespace\MyClass::MY_CONSTANT`)
+- Property expressions (i.e. `@see \MyNamespace\MyClass::$myProperty`)
+- Method expressions (i.e. `@see \MyNamespace\MyClass::myMethod()`)
+
+## Resolving a type
+
+In order to resolve a type you will have to instantiate the class `\phpDocumentor\Reflection\TypeResolver`
+and call its `resolve` method like this:
+
+```php
+$typeResolver = new \phpDocumentor\Reflection\TypeResolver();
+$type = $typeResolver->resolve('string|integer');
+```
+
+In this example you will receive a Value Object of class `\phpDocumentor\Reflection\Types\Compound` that has two 
+elements, one of type `\phpDocumentor\Reflection\Types\String_` and one of type 
+`\phpDocumentor\Reflection\Types\Integer`.
+
+The real power of this resolver is in its capability to expand partial class names into fully qualified class names; but
+in order to do that we need an additional `\phpDocumentor\Reflection\Types\Context` class that will inform the resolver 
+in which namespace the given expression occurs and which namespace aliases (or imports) apply.
+
+## Resolving an FQSEN
+
+A Fully Qualified Structural Element Name is a reference to another element in your code bases and can be resolved using
+the `\phpDocumentor\Reflection\FqsenResolver` class' `resolve` method, like this:
+
+```php
+$fqsenResolver = new \phpDocumentor\Reflection\FqsenResolver();
+$fqsen = $fqsenResolver->resolve('\phpDocumentor\Reflection\FqsenResolver::resolve()');
+```
+
+In this example we resolve a Fully Qualified Structural Element Name (meaning that it includes the full namespace, class
+name and element name) and receive a Value Object of type `\phpDocumentor\Reflection\Fqsen`.
+
+The real power of this resolver is in its capability to expand partial element names into Fully Qualified Structural 
+Element Names; but in order to do that we need an additional `\phpDocumentor\Reflection\Types\Context` class that will 
+inform the resolver in which namespace the given expression occurs and which namespace aliases (or imports) apply.
+
+## Resolving partial Classes and Structural Element Names
+
+Perhaps the best feature of this library is that it knows how to resolve partial class names into fully qualified class 
+names.
+
+For example, you have this file:
+
+```php
+namespace My\Example;
+
+use phpDocumentor\Reflection\Types;
+
+class Classy
+{
+    /**
+     * @var Types\Context
+     * @see Classy::otherFunction()
+     */
+    public function __construct($context) {}
+    
+    public function otherFunction(){}
+}
+```
+
+Suppose that you would want to resolve (and expand) the type in the `@var` tag and the element name in the `@see` tag.
+For the resolvers to know how to expand partial names you have to provide a bit of _Context_ for them by instantiating
+a new class named `\phpDocumentor\Reflection\Types\Context` with the name of the namespace and the aliases that are in 
+play.
+
+### Creating a Context
+
+You can do this by manually creating a Context like this:
+
+```php
+$context = new \phpDocumentor\Reflection\Types\Context(
+    '\My\Example', 
+    [ 'Types' => '\phpDocumentor\Reflection\Types']
+);
+```
+
+Or by using the `\phpDocumentor\Reflection\Types\ContextFactory` to instantiate a new context based on a Reflector 
+object or by providing the namespace that you'd like to extract and the source code of the file in which the given
+type expression occurs.
+
+```php
+$contextFactory = new \phpDocumentor\Reflection\Types\ContextFactory();
+$context = $contextFactory->createFromReflector(new ReflectionMethod('\My\Example\Classy', '__construct'));
+```
+
+or
+
+```php
+$contextFactory = new \phpDocumentor\Reflection\Types\ContextFactory();
+$context = $contextFactory->createForNamespace('\My\Example', file_get_contents('My/Example/Classy.php'));
+```
+
+### Using the Context
+
+After you have obtained a Context it is just a matter of passing it along with the `resolve` method of either Resolver 
+class as second argument and the Resolvers will take this into account when resolving partial names.
+
+To obtain the resolved class name for the `@var` tag in the example above you can do:
+
+```php
+$typeResolver = new \phpDocumentor\Reflection\TypeResolver();
+$type = $typeResolver->resolve('Types\Context', $context);
+```
+
+When you do this you will receive an object of class `\phpDocumentor\Reflection\Types\Object_` for which you can call 
+the `getFqsen` method to receive a Value Object that represents the complete FQSEN. So that would be 
+`phpDocumentor\Reflection\Types\Context`.
+
+> Why is the FQSEN wrapped in another object `Object_`?
+> 
+> The resolve method of the TypeResolver only returns object with the interface `Type` and the FQSEN is a common
+> type that does not represent a Type. Also: in some cases a type can represent an "Untyped Object", meaning that it
+> is an object (signified by the `object` keyword) but does not refer to a specific element using an FQSEN.
+
+Another example is on how to resolve the FQSEN of a method as can be seen with the `@see` tag in the example above. To
+resolve that you can do the following:
+
+```php
+$fqsenResolver = new \phpDocumentor\Reflection\FqsenResolver();
+$type = $fqsenResolver->resolve('Classy::otherFunction()', $context);
+```
+
+Because Classy is a Class in the current namespace its FQSEN will have the `My\Example` namespace and by calling the 
+`resolve` method of the FQSEN Resolver you will receive an `Fqsen` object that refers to 
+`\My\Example\Classy::otherFunction()`.

+# Prophecy
+
+[![Stable release](https://poser.pugx.org/phpspec/prophecy/version.svg)](https://packagist.org/packages/phpspec/prophecy)
+[![Build Status](https://travis-ci.org/phpspec/prophecy.svg?branch=master)](https://travis-ci.org/phpspec/prophecy)
+
+Prophecy is a highly opinionated yet very powerful and flexible PHP object mocking
+framework. Though initially it was created to fulfil phpspec2 needs, it is flexible
+enough to be used inside any testing framework out there with minimal effort.
+
+## A simple example
+
+```php
+<?php
+
+class UserTest extends PHPUnit_Framework_TestCase
+{
+    private $prophet;
+
+    public function testPasswordHashing()
+    {
+        $hasher = $this->prophet->prophesize('App\Security\Hasher');
+        $user   = new App\Entity\User($hasher->reveal());
+
+        $hasher->generateHash($user, 'qwerty')->willReturn('hashed_pass');
+
+        $user->setPassword('qwerty');
+
+        $this->assertEquals('hashed_pass', $user->getPassword());
+    }
+
+    protected function setup()
+    {
+        $this->prophet = new \Prophecy\Prophet;
+    }
+
+    protected function tearDown()
+    {
+        $this->prophet->checkPredictions();
+    }
+}
+```
+
+## Installation
+
+### Prerequisites
+
+Prophecy requires PHP 5.3.3 or greater.
+
+### Setup through composer
+
+First, add Prophecy to the list of dependencies inside your `composer.json`:
+
+```json
+{
+    "require-dev": {
+        "phpspec/prophecy": "~1.0"
+    }
+}
+```
+
+Then simply install it with composer:
+
+```bash
+$> composer install --prefer-dist
+```
+
+You can read more about Composer on its [official webpage](http://getcomposer.org).
+
+## How to use it
+
+First of all, in Prophecy every word has a logical meaning, even the name of the library
+itself (Prophecy). When you start feeling that, you'll become very fluid with this
+tool.
+
+For example, Prophecy has been named that way because it concentrates on describing the future
+behavior of objects with very limited knowledge about them. But as with any other prophecy,
+those object prophecies can't create themselves - there should be a Prophet:
+
+```php
+$prophet = new Prophecy\Prophet;
+```
+
+The Prophet creates prophecies by *prophesizing* them:
+
+```php
+$prophecy = $prophet->prophesize();
+```
+
+The result of the `prophesize()` method call is a new object of class `ObjectProphecy`. Yes,
+that's your specific object prophecy, which describes how your object would behave
+in the near future. But first, you need to specify which object you're talking about,
+right?
+
+```php
+$prophecy->willExtend('stdClass');
+$prophecy->willImplement('SessionHandlerInterface');
+```
+
+There are 2 interesting calls - `willExtend` and `willImplement`. The first one tells
+object prophecy that our object should extend specific class, the second one says that
+it should implement some interface. Obviously, objects in PHP can implement multiple
+interfaces, but extend only one parent class.
+
+### Dummies
+
+Ok, now we have our object prophecy. What can we do with it? First of all, we can get
+our object *dummy* by revealing its prophecy:
+
+```php
+$dummy = $prophecy->reveal();
+```
+
+The `$dummy` variable now holds a special dummy object. Dummy objects are objects that extend
+and/or implement preset classes/interfaces by overriding all their public methods. The key
+point about dummies is that they do not hold any logic - they just do nothing. Any method
+of the dummy will always return `null` and the dummy will never throw any exceptions.
+Dummy is your friend if you don't care about the actual behavior of this double and just need
+a token object to satisfy a method typehint.
+
+You need to understand one thing - a dummy is not a prophecy. Your object prophecy is still
+assigned to `$prophecy` variable and in order to manipulate with your expectations, you
+should work with it. `$dummy` is a dummy - a simple php object that tries to fulfil your
+prophecy.
+
+### Stubs
+
+Ok, now we know how to create basic prophecies and reveal dummies from them. That's
+awesome if we don't care about our _doubles_ (objects that reflect originals)
+interactions. If we do, we need to use *stubs* or *mocks*.
+
+A stub is an object double, which doesn't have any expectations about the object behavior,
+but when put in specific environment, behaves in specific way. Ok, I know, it's cryptic,
+but bear with me for a minute. Simply put, a stub is a dummy, which depending on the called
+method signature does different things (has logic). To create stubs in Prophecy:
+
+```php
+$prophecy->read('123')->willReturn('value');
+```
+
+Oh wow. We've just made an arbitrary call on the object prophecy? Yes, we did. And this
+call returned us a new object instance of class `MethodProphecy`. Yep, that's a specific
+method with arguments prophecy. Method prophecies give you the ability to create method
+promises or predictions. We'll talk about method predictions later in the _Mocks_ section.
+
+#### Promises
+
+Promises are logical blocks, that represent your fictional methods in prophecy terms
+and they are handled by the `MethodProphecy::will(PromiseInterface $promise)` method.
+As a matter of fact, the call that we made earlier (`willReturn('value')`) is a simple
+shortcut to:
+
+```php
+$prophecy->read('123')->will(new Prophecy\Promise\ReturnPromise(array('value')));
+```
+
+This promise will cause any call to our double's `read()` method with exactly one
+argument - `'123'` to always return `'value'`. But that's only for this
+promise, there's plenty others you can use:
+
+- `ReturnPromise` or `->willReturn(1)` - returns a value from a method call
+- `ReturnArgumentPromise` or `->willReturnArgument($index)` - returns the nth method argument from call
+- `ThrowPromise` or `->willThrow($exception)` - causes the method to throw specific exception
+- `CallbackPromise` or `->will($callback)` - gives you a quick way to define your own custom logic
+
+Keep in mind, that you can always add even more promises by implementing
+`Prophecy\Promise\PromiseInterface`.
+
+#### Method prophecies idempotency
+
+Prophecy enforces same method prophecies and, as a consequence, same promises and
+predictions for the same method calls with the same arguments. This means:
+
+```php
+$methodProphecy1 = $prophecy->read('123');
+$methodProphecy2 = $prophecy->read('123');
+$methodProphecy3 = $prophecy->read('321');
+
+$methodProphecy1 === $methodProphecy2;
+$methodProphecy1 !== $methodProphecy3;
+```
+
+That's interesting, right? Now you might ask me how would you define more complex
+behaviors where some method call changes behavior of others. In PHPUnit or Mockery
+you do that by predicting how many times your method will be called. In Prophecy,
+you'll use promises for that:
+
+```php
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName('everzet')->will(function () {
+    $this->getName()->willReturn('everzet');
+});
+
+// For PHP 5.3
+$user->setName('everzet')->will(function ($args, $user) {
+    $user->getName()->willReturn('everzet');
+});
+
+// Or
+$user->setName('everzet')->will(function ($args) use ($user) {
+    $user->getName()->willReturn('everzet');
+});
+```
+
+And now it doesn't matter how many times or in which order your methods are called.
+What matters is their behaviors and how well you faked it.
+
+#### Arguments wildcarding
+
+The previous example is awesome (at least I hope it is for you), but that's not
+optimal enough. We hardcoded `'everzet'` in our expectation. Isn't there a better
+way? In fact there is, but it involves understanding what this `'everzet'`
+actually is.
+
+You see, even if method arguments used during method prophecy creation look
+like simple method arguments, in reality they are not. They are argument token
+wildcards.  As a matter of fact, `->setName('everzet')` looks like a simple call just
+because Prophecy automatically transforms it under the hood into:
+
+```php
+$user->setName(new Prophecy\Argument\Token\ExactValueToken('everzet'));
+```
+
+Those argument tokens are simple PHP classes, that implement
+`Prophecy\Argument\Token\TokenInterface` and tell Prophecy how to compare real arguments
+with your expectations. And yes, those classnames are damn big. That's why there's a
+shortcut class `Prophecy\Argument`, which you can use to create tokens like that:
+
+```php
+use Prophecy\Argument;
+
+$user->setName(Argument::exact('everzet'));
+```
+
+`ExactValueToken` is not very useful in our case as it forced us to hardcode the username.
+That's why Prophecy comes bundled with a bunch of other tokens:
+
+- `IdenticalValueToken` or `Argument::is($value)` - checks that the argument is identical to a specific value
+- `ExactValueToken` or `Argument::exact($value)` - checks that the argument matches a specific value
+- `TypeToken` or `Argument::type($typeOrClass)` - checks that the argument matches a specific type or
+  classname
+- `ObjectStateToken` or `Argument::which($method, $value)` - checks that the argument method returns
+  a specific value
+- `CallbackToken` or `Argument::that(callback)` - checks that the argument matches a custom callback
+- `AnyValueToken` or `Argument::any()` - matches any argument
+- `AnyValuesToken` or `Argument::cetera()` - matches any arguments to the rest of the signature
+- `StringContainsToken` or `Argument::containingString($value)` - checks that the argument contains a specific string value
+
+And you can add even more by implementing `TokenInterface` with your own custom classes.
+
+So, let's refactor our initial `{set,get}Name()` logic with argument tokens:
+
+```php
+use Prophecy\Argument;
+
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName(Argument::type('string'))->will(function ($args) {
+    $this->getName()->willReturn($args[0]);
+});
+
+// For PHP 5.3
+$user->setName(Argument::type('string'))->will(function ($args, $user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+// Or
+$user->setName(Argument::type('string'))->will(function ($args) use ($user) {
+    $user->getName()->willReturn($args[0]);
+});
+```
+
+That's it. Now our `{set,get}Name()` prophecy will work with any string argument provided to it.
+We've just described how our stub object should behave, even though the original object could have
+no behavior whatsoever.
+
+One last bit about arguments now. You might ask, what happens in case of:
+
+```php
+use Prophecy\Argument;
+
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName(Argument::type('string'))->will(function ($args) {
+    $this->getName()->willReturn($args[0]);
+});
+
+// For PHP 5.3
+$user->setName(Argument::type('string'))->will(function ($args, $user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+// Or
+$user->setName(Argument::type('string'))->will(function ($args) use ($user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+$user->setName(Argument::any())->will(function () {
+});
+```
+
+Nothing. Your stub will continue behaving the way it did before. That's because of how
+arguments wildcarding works. Every argument token type has a different score level, which
+wildcard then uses to calculate the final arguments match score and use the method prophecy
+promise that has the highest score. In this case, `Argument::type()` in case of success
+scores `5` and `Argument::any()` scores `3`. So the type token wins, as does the first
+`setName()` method prophecy and its promise. The simple rule of thumb - more precise token
+always wins.
+
+#### Getting stub objects
+
+Ok, now we know how to define our prophecy method promises, let's get our stub from
+it:
+
+```php
+$stub = $prophecy->reveal();
+```
+
+As you might see, the only difference between how we get dummies and stubs is that with
+stubs we describe every object conversation instead of just agreeing with `null` returns
+(object being *dummy*). As a matter of fact, after you define your first promise
+(method call), Prophecy will force you to define all the communications - it throws
+the `UnexpectedCallException` for any call you didn't describe with object prophecy before
+calling it on a stub.
+
+### Mocks
+
+Now we know how to define doubles without behavior (dummies) and doubles with behavior, but
+no expectations (stubs). What's left is doubles for which we have some expectations. These
+are called mocks and in Prophecy they look almost exactly the same as stubs, except that
+they define *predictions* instead of *promises* on method prophecies:
+
+```php
+$entityManager->flush()->shouldBeCalled();
+```
+
+#### Predictions
+
+The `shouldBeCalled()` method here assigns `CallPrediction` to our method prophecy.
+Predictions are a delayed behavior check for your prophecies. You see, during the entire lifetime
+of your doubles, Prophecy records every single call you're making against it inside your
+code. After that, Prophecy can use this collected information to check if it matches defined
+predictions. You can assign predictions to method prophecies using the
+`MethodProphecy::should(PredictionInterface $prediction)` method. As a matter of fact,
+the `shouldBeCalled()` method we used earlier is just a shortcut to:
+
+```php
+$entityManager->flush()->should(new Prophecy\Prediction\CallPrediction());
+```
+
+It checks if your method of interest (that matches both the method name and the arguments wildcard)
+was called 1 or more times. If the prediction failed then it throws an exception. When does this
+check happen? Whenever you call `checkPredictions()` on the main Prophet object:
+
+```php
+$prophet->checkPredictions();
+```
+
+In PHPUnit, you would want to put this call into the `tearDown()` method. If no predictions
+are defined, it would do nothing. So it won't harm to call it after every test.
+
+There are plenty more predictions you can play with:
+
+- `CallPrediction` or `shouldBeCalled()` - checks that the method has been called 1 or more times
+- `NoCallsPrediction` or `shouldNotBeCalled()` - checks that the method has not been called
+- `CallTimesPrediction` or `shouldBeCalledTimes($count)` - checks that the method has been called
+  `$count` times
+- `CallbackPrediction` or `should($callback)` - checks the method against your own custom callback
+
+Of course, you can always create your own custom prediction any time by implementing
+`PredictionInterface`.
+
+### Spies
+
+The last bit of awesomeness in Prophecy is out-of-the-box spies support. As I said in the previous
+section, Prophecy records every call made during the double's entire lifetime. This means
+you don't need to record predictions in order to check them. You can also do it
+manually by using the `MethodProphecy::shouldHave(PredictionInterface $prediction)` method:
+
+```php
+$em = $prophet->prophesize('Doctrine\ORM\EntityManager');
+
+$controller->createUser($em->reveal());
+
+$em->flush()->shouldHaveBeenCalled();
+```
+
+Such manipulation with doubles is called spying. And with Prophecy it just works.

+[![Latest Stable Version](https://poser.pugx.org/phpunit/php-code-coverage/v/stable.png)](https://packagist.org/packages/phpunit/php-code-coverage)

+
+# PHP_CodeCoverage
+
+**PHP_CodeCoverage** is a library that provides collection, processing, and rendering functionality for PHP code coverage information.
+
+## Requirements
+
+PHP 5.6 is required but using the latest version of PHP is highly recommended.
+
+### PHP 5
+
+[Xdebug](http://xdebug.org/) is the only source of raw code coverage data supported for PHP 5. Version 2.2.1 of Xdebug is required but using the latest version is highly recommended.
+
+### PHP 7
+
+Version 2.4.0 (or later) of [Xdebug](http://xdebug.org/) as well as [phpdbg](http://phpdbg.com/docs) are supported sources of raw code coverage data for PHP 7.
+
+### HHVM
+
+A version of HHVM that implements the Xdebug API for code coverage (`xdebug_*_code_coverage()`) is required.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phpunit/php-code-coverage
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phpunit/php-code-coverage
+
+## Using the PHP_CodeCoverage API
+
+```php
+<?php
+$coverage = new \SebastianBergmann\CodeCoverage\CodeCoverage;
+$coverage->start('<name of test>');
+
+// ...
+
+$coverage->stop();
+
+$writer = new \SebastianBergmann\CodeCoverage\Report\Clover;
+$writer->process($coverage, '/tmp/clover.xml');
+
+$writer = new \SebastianBergmann\CodeCoverage\Report\Html\Facade;
+$writer->process($coverage, '/tmp/code-coverage-report');
+```

+
+## Installation
+
+## Installation
+
+To add this package as a local, per-project dependency to your project, simply add a dependency on `phpunit/php-text-template` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on Text_Template:
+
+    {
+        "require": {

+
+# PHP_Timer
+
+Utility class for timing things, factored out of PHPUnit into a stand-alone component.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phpunit/php-timer
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phpunit/php-timer
+
+## Usage
+
+### Basic Timing
+
+```php
+PHP_Timer::start();
+
+// ...
+
+$time = PHP_Timer::stop();
+var_dump($time);
+
+print PHP_Timer::secondsToTimeString($time);
+```
+
+The code above yields the output below:
+
+    double(1.0967254638672E-5)
+    0 ms
+
+### Resource Consumption Since PHP Startup
+
+```php
+print PHP_Timer::resourceUsage();
+```
+
+The code above yields the output below:
+
+    Time: 0 ms, Memory: 0.50MB

+# PHPUnit_MockObject
+
+**PHPUnit_MockObject** is the default mock object library for PHPUnit.
+
+## Requirements
+
+* PHP 5.6 is required but using the latest version of PHP is highly recommended
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phpunit/phpunit-mock-objects
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phpunit/phpunit-mock-objects
+

+# Contributor Code of Conduct
+
+As contributors and maintainers of this project, and in the interest of fostering an open and welcoming community, we pledge to respect all people who contribute through reporting issues, posting feature requests, updating documentation, submitting pull requests or patches, and other activities.
+
+We are committed to making participation in this project a harassment-free experience for everyone, regardless of level of experience, gender, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, ethnicity, age, religion, or nationality.
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery
+* Personal attacks
+* Trolling or insulting/derogatory comments
+* Public or private harassment
+* Publishing other's private information, such as physical or electronic
+  addresses, without explicit permission
+* Other unethical or unprofessional conduct
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+By adopting this Code of Conduct, project maintainers commit themselves to fairly and consistently applying these principles to every aspect of managing this project. Project maintainers who do not follow or enforce the Code of Conduct may be permanently removed from the project team.
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community.
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project maintainer at sebastian@phpunit.de. All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. Maintainers are obligated to maintain confidentiality with regard to the reporter of an incident.
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.3.0, available at [http://contributor-covenant.org/version/1/3/0/][version]

+# Contributing to PHPUnit
+
+## Contributor Code of Conduct
+
+Please note that this project is released with a [Contributor Code of Conduct](CODE_OF_CONDUCT.md). By participating in this project you agree to abide by its terms.
+
+## Workflow
+
+* Fork the project.
+* Make your bug fix or feature addition.
+* Add tests for it. This is important so we don't break it in a future version unintentionally.
+* Send a pull request. Bonus points for topic branches.
+
+Please make sure that you have [set up your user name and email address](http://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup) for use with Git. Strings such as `silly nick name <root@localhost>` look really stupid in the commit history of a project.
+
+Pull requests for bug fixes must be based on the current stable branch whereas pull requests for new features must be based on the `master` branch.
+
+We are trying to keep backwards compatibility breaks in PHPUnit to an absolute minimum. Please take this into account when proposing changes.
+
+Due to time constraints, we are not always able to respond as quickly as we would like. Please do not take delays personal and feel free to remind us if you feel that we forgot to respond.
+
+## Coding Guidelines
+
+This project comes with a configuration file for [php-cs-fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer) (`.php_cs`) that you can use to (re)format your sourcecode for compliance with this project's coding guidelines:
+
+```bash
+$ wget http://cs.sensiolabs.org/download/php-cs-fixer-v2.phar -O php-cs-fixer.phar
+
+$ php php-cs-fixer.phar fix
+```
+
+## Using PHPUnit from a Git checkout
+
+The following commands can be used to perform the initial checkout of PHPUnit:
+
+```bash
+$ git clone git://github.com/sebastianbergmann/phpunit.git
+
+$ cd phpunit
+```
+
+Retrieve PHPUnit's dependencies using [Composer](https://getcomposer.org/):
+
+```bash
+$ composer install
+```
+
+The `phpunit` script can be used to invoke the PHPUnit test runner:
+
+```bash
+$ ./phpunit --version
+```
+
+## Running PHPUnit's own test suite
+
+After following the steps shown above, PHPUnit's own test suite is run like this:
+
+```bash
+$ ./phpunit
+```
+
+## Reporting issues
+
+Please use the most specific issue tracker to search for existing tickets and to open new tickets:
+
+* [General problems](https://github.com/sebastianbergmann/phpunit/issues)
+* [Code Coverage](https://github.com/sebastianbergmann/php-code-coverage/issues)
+* [Stub and Mock Objects](https://github.com/sebastianbergmann/phpunit-mock-objects/issues)
+* [DbUnit](https://github.com/sebastianbergmann/dbunit/issues)
+* [Documentation](https://github.com/sebastianbergmann/phpunit-documentation/issues)
+* [Website](https://github.com/sebastianbergmann/phpunit-website/issues)

+# PHPUnit
+
+PHPUnit is a programmer-oriented testing framework for PHP. It is an instance of the xUnit architecture for unit testing frameworks.
+
+[![Latest Stable Version](https://img.shields.io/packagist/v/phpunit/phpunit.svg?style=flat-square)](https://packagist.org/packages/phpunit/phpunit)
+[![Minimum PHP Version](https://img.shields.io/badge/php-%3E%3D%205.6-8892BF.svg?style=flat-square)](https://php.net/)
+[![Build Status](https://img.shields.io/travis/sebastianbergmann/phpunit/5.7.svg?style=flat-square)](https://phpunit.de/build-status.html)
+
+## Installation
+
+We distribute a [PHP Archive (PHAR)](https://php.net/phar) that has all required (as well as some optional) dependencies of PHPUnit bundled in a single file:
+
+```bash
+$ wget https://phar.phpunit.de/phpunit.phar
+
+$ chmod +x phpunit.phar
+
+$ mv phpunit.phar /usr/local/bin/phpunit
+```
+
+You can also immediately use the PHAR after you have downloaded it, of course:
+
+```bash
+$ wget https://phar.phpunit.de/phpunit.phar
+
+$ php phpunit.phar
+```
+
+Alternatively, you may use [Composer](https://getcomposer.org/) to download and install PHPUnit as well as its dependencies. Please refer to the [documentation](https://phpunit.de/documentation.html) for details on how to do this.
+
+## Contribute
+
+Please refer to [CONTRIBUTING.md](https://github.com/sebastianbergmann/phpunit/blob/master/.github/CONTRIBUTING.md) for information on how to contribute to PHPUnit and its related projects.

+/**
+ * A TestCase defines the fixture to run multiple tests.
+ *
+ * To define a TestCase
+ *
+ *   1) Implement a subclass of PHPUnit_Framework_TestCase.
+ *   2) Define instance variables that store the state of the fixture.
+ *   3) Initialize the fixture state by overriding setUp().
+ *   4) Clean-up after a test by overriding tearDown().
+ *
+ * Each test runs in its own fixture so there can be no side effects
+ * among test runs.
+ *
+ * Here is an example:
+ *
+ * <code>
+ * <?php
+ * class MathTest extends PHPUnit_Framework_TestCase
+ * {
+ *     public $value1;
+ *     public $value2;
+ *
+ *     protected function setUp()
+ *     {
+ *         $this->value1 = 2;
+ *         $this->value2 = 3;
+ *     }
+ * }
+ * ?>
+ * </code>
+ *
+ * For each test implement a method which interacts with the fixture.
+ * Verify the expected results with assertions specified by calling
+ * assert with a boolean.
+ *
+ * <code>
+ * <?php
+ * public function testPass()
+ * {
+ *     $this->assertTrue($this->value1 + $this->value2 == 5);
+ * }
+ * ?>

+Pimple
+======
+
+.. caution::
+
+    This is the documentation for Pimple 3.x. If you are using Pimple 1.x, read
+    the `Pimple 1.x documentation`_. Reading the Pimple 1.x code is also a good
+    way to learn more about how to create a simple Dependency Injection
+    Container (recent versions of Pimple are more focused on performance).
+
+Pimple is a small Dependency Injection Container for PHP.
+
+Installation
+------------
+
+Before using Pimple in your project, add it to your ``composer.json`` file:
+
+.. code-block:: bash
+
+    $ ./composer.phar require pimple/pimple "^3.0"
+
+Usage
+-----
+
+Creating a container is a matter of creating a ``Container`` instance:
+
+.. code-block:: php
+
+    use Pimple\Container;
+
+    $container = new Container();
+
+As many other dependency injection containers, Pimple manages two different
+kind of data: **services** and **parameters**.
+
+Defining Services
+~~~~~~~~~~~~~~~~~
+
+A service is an object that does something as part of a larger system. Examples
+of services: a database connection, a templating engine, or a mailer. Almost
+any **global** object can be a service.
+
+Services are defined by **anonymous functions** that return an instance of an
+object:
+
+.. code-block:: php
+
+    // define some services
+    $container['session_storage'] = function ($c) {
+        return new SessionStorage('SESSION_ID');
+    };
+
+    $container['session'] = function ($c) {
+        return new Session($c['session_storage']);
+    };
+
+Notice that the anonymous function has access to the current container
+instance, allowing references to other services or parameters.
+
+As objects are only created when you get them, the order of the definitions
+does not matter.
+
+Using the defined services is also very easy:
+
+.. code-block:: php
+
+    // get the session object
+    $session = $container['session'];
+
+    // the above call is roughly equivalent to the following code:
+    // $storage = new SessionStorage('SESSION_ID');
+    // $session = new Session($storage);
+
+Defining Factory Services
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, each time you get a service, Pimple returns the **same instance**
+of it. If you want a different instance to be returned for all calls, wrap your
+anonymous function with the ``factory()`` method
+
+.. code-block:: php
+
+    $container['session'] = $container->factory(function ($c) {
+        return new Session($c['session_storage']);
+    });
+
+Now, each call to ``$container['session']`` returns a new instance of the
+session.
+
+Defining Parameters
+~~~~~~~~~~~~~~~~~~~
+
+Defining a parameter allows to ease the configuration of your container from
+the outside and to store global values:
+
+.. code-block:: php
+
+    // define some parameters
+    $container['cookie_name'] = 'SESSION_ID';
+    $container['session_storage_class'] = 'SessionStorage';
+
+If you change the ``session_storage`` service definition like below:
+
+.. code-block:: php
+
+    $container['session_storage'] = function ($c) {
+        return new $c['session_storage_class']($c['cookie_name']);
+    };
+
+You can now easily change the cookie name by overriding the
+``cookie_name`` parameter instead of redefining the service
+definition.
+
+Protecting Parameters
+~~~~~~~~~~~~~~~~~~~~~
+
+Because Pimple sees anonymous functions as service definitions, you need to
+wrap anonymous functions with the ``protect()`` method to store them as
+parameters:
+
+.. code-block:: php
+
+    $container['random_func'] = $container->protect(function () {
+        return rand();
+    });
+
+Modifying Services after Definition
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In some cases you may want to modify a service definition after it has been
+defined. You can use the ``extend()`` method to define additional code to be
+run on your service just after it is created:
+
+.. code-block:: php
+
+    $container['session_storage'] = function ($c) {
+        return new $c['session_storage_class']($c['cookie_name']);
+    };
+
+    $container->extend('session_storage', function ($storage, $c) {
+        $storage->...();
+
+        return $storage;
+    });
+
+The first argument is the name of the service to extend, the second a function
+that gets access to the object instance and the container.
+
+Extending a Container
+~~~~~~~~~~~~~~~~~~~~~
+
+If you use the same libraries over and over, you might want to reuse some
+services from one project to the next one; package your services into a
+**provider** by implementing ``Pimple\ServiceProviderInterface``:
+
+.. code-block:: php
+
+    use Pimple\Container;
+
+    class FooProvider implements Pimple\ServiceProviderInterface
+    {
+        public function register(Container $pimple)
+        {
+            // register some services and parameters
+            // on $pimple
+        }
+    }
+
+Then, register the provider on a Container:
+
+.. code-block:: php
+
+    $pimple->register(new FooProvider());
+
+Fetching the Service Creation Function
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When you access an object, Pimple automatically calls the anonymous function
+that you defined, which creates the service object for you. If you want to get
+raw access to this function, you can use the ``raw()`` method:
+
+.. code-block:: php
+
+    $container['session'] = function ($c) {
+        return new Session($c['session_storage']);
+    };
+
+    $sessionFunction = $container->raw('session');
+
+PSR-11 compatibility
+--------------------
+
+For historical reasons, the ``Container`` class does not implement the PSR-11
+``ContainerInterface``. However, Pimple provides a helper class that will let
+you decouple your code from the Pimple container class.
+
+The PSR-11 container class
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``Pimple\Psr11\Container`` class lets you access the content of an
+underlying Pimple container using ``Psr\Container\ContainerInterface``
+methods:
+
+.. code-block:: php
+
+    use Pimple\Container;
+    use Pimple\Psr11\Container as PsrContainer;
+
+    $container = new Container();
+    $container['service'] = function ($c) {
+        return new Service();
+    };
+    $psr11 = new PsrContainer($container);
+
+    $controller = function (PsrContainer $container) {
+        $service = $container->get('service');
+    };
+    $controller($psr11);
+
+Using the PSR-11 ServiceLocator
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sometimes, a service needs access to several other services without being sure
+that all of them will actually be used. In those cases, you may want the
+instantiation of the services to be lazy.
+
+The traditional solution is to inject the entire service container to get only
+the services really needed. However, this is not recommended because it gives
+services a too broad access to the rest of the application and it hides their
+actual dependencies.
+
+The ``ServiceLocator`` is intended to solve this problem by giving access to a
+set of predefined services while instantiating them only when actually needed.
+
+It also allows you to make your services available under a different name than
+the one used to register them. For instance, you may want to use an object
+that expects an instance of ``EventDispatcherInterface`` to be available under
+the name ``event_dispatcher`` while your event dispatcher has been
+registered under the name ``dispatcher``:
+
+.. code-block:: php
+
+    use Monolog\Logger;
+    use Pimple\Psr11\ServiceLocator;
+    use Psr\Container\ContainerInterface;
+    use Symfony\Component\EventDispatcher\EventDispatcher;
+
+    class MyService
+    {
+        /**
+         * "logger" must be an instance of Psr\Log\LoggerInterface
+         * "event_dispatcher" must be an instance of Symfony\Component\EventDispatcher\EventDispatcherInterface
+         */
+        private $services;
+
+        public function __construct(ContainerInterface $services)
+        {
+            $this->services = $services;
+        }
+    }
+
+    $container['logger'] = function ($c) {
+        return new Monolog\Logger();
+    };
+    $container['dispatcher'] = function () {
+        return new EventDispatcher();
+    };
+
+    $container['service'] = function ($c) {
+        $locator = new ServiceLocator($c, array('logger', 'event_dispatcher' => 'dispatcher'));
+
+        return new MyService($locator);
+    };
+
+Referencing a Collection of Services Lazily
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Passing a collection of services instances in an array may prove inefficient
+if the class that consumes the collection only needs to iterate over it at a
+later stage, when one of its method is called. It can also lead to problems
+if there is a circular dependency between one of the services stored in the
+collection and the class that consumes it.
+
+The ``ServiceIterator`` class helps you solve these issues. It receives a
+list of service names during instantiation and will retrieve the services
+when iterated over:
+
+.. code-block:: php
+
+    use Pimple\Container;
+    use Pimple\ServiceIterator;
+
+    class AuthorizationService
+    {
+        private $voters;
+
+        public function __construct($voters)
+        {
+            $this->voters = $voters;
+        }
+
+        public function canAccess($resource)
+        {
+            foreach ($this->voters as $voter) {
+                if (true === $voter->canAccess($resource) {
+                    return true;
+                }
+            }
+
+            return false;
+        }
+    }
+
+    $container = new Container();
+
+    $container['voter1'] = function ($c) {
+        return new SomeVoter();
+    }
+    $container['voter2'] = function ($c) {
+        return new SomeOtherVoter($c['auth']);
+    }
+    $container['auth'] = function ($c) {
+        return new AuthorizationService(new ServiceIterator($c, array('voter1', 'voter2'));
+    }

+# Changelog
+
+All notable changes to this project will be documented in this file, in reverse chronological order by release.
+
+## 1.0.1 - 2016-08-06
+
+### Fixed
+
+- Make spacing consistent in phpdoc annotations php-fig/cache#9 - chalasr
+- Fix grammar in phpdoc annotations php-fig/cache#10 - chalasr
+- Be more specific in docblocks that `getItems()` and `deleteItems()` take an array of strings (`string[]`) compared to just `array` php-fig/cache#8 - GrahamCampbell
+- For `expiresAt()` and `expiresAfter()` in CacheItemInterface fix docblock to specify null as a valid parameters as well as an implementation of DateTimeInterface php-fig/cache#7 - GrahamCampbell
+
+## 1.0.0 - 2015-12-11
+
+Initial stable release; reflects accepted PSR-6 specification

+# Changelog
+
+All notable changes to this project will be documented in this file, in reverse chronological order by release.
+
+## 1.0.1 - 2016-08-06
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Updated all `@return self` annotation references in interfaces to use
+  `@return static`, which more closelly follows the semantics of the
+  specification.
+- Updated the `MessageInterface::getHeaders()` return annotation to use the
+  value `string[][]`, indicating the format is a nested array of strings.
+- Updated the `@link` annotation for `RequestInterface::withRequestTarget()`
+  to point to the correct section of RFC 7230.
+- Updated the `ServerRequestInterface::withUploadedFiles()` parameter annotation
+  to add the parameter name (`$uploadedFiles`).
+- Updated a `@throws` annotation for the `UploadedFileInterface::moveTo()`
+  method to correctly reference the method parameter (it was referencing an
+  incorrect parameter name previously).
+
+## 1.0.0 - 2016-05-18
+
+Initial stable release; reflects accepted PSR-7 specification.

+PSR Http Message
+================
+
+This repository holds all interfaces/classes/traits related to
+[PSR-7](http://www.php-fig.org/psr/psr-7/).
+
+Note that this is not a HTTP message implementation of its own. It is merely an
+interface that describes a HTTP message. See the specification for more details.
+
+Usage
+-----
+
+We'll certainly need some stuff in here.

+PSR Log
+=======
+
+This repository holds all interfaces/classes/traits related to
+[PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md).
+
+Note that this is not a logger of its own. It is merely an interface that
+describes a logger. See the specification for more details.
+
+Usage
+-----
+
+If you need a logger, you can use the interface like this:
+
+```php
+<?php
+
+use Psr\Log\LoggerInterface;
+
+class Foo
+{
+    private $logger;
+
+    public function __construct(LoggerInterface $logger = null)
+    {
+        $this->logger = $logger;
+    }
+
+    public function doSomething()
+    {
+        if ($this->logger) {
+            $this->logger->info('Doing work');
+        }
+
+        // do something useful
+    }
+}
+```
+
+You can then pick one of the implementations of the interface to get a logger.
+
+If you want to implement the interface, you can require this package and
+implement `Psr\Log\LoggerInterface` in your code. Please read the
+[specification text](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
+for details.

+PHP FIG Simple Cache PSR
+========================
+
+This repository holds all interfaces related to PSR-16.
+
+Note that this is not a cache implementation of its own. It is merely an interface that describes a cache implementation. See [the specification](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-16-simple-cache.md) for more details.
+
+You can find implementations of the specification by looking for packages providing the [psr/simple-cache-implementation](https://packagist.org/providers/psr/simple-cache-implementation) virtual package.

+# ramsey/uuid Changelog
+
+## 3.7.3
+
+_Released: 2018-01-19_
+
+  * In rare cases, when using `glob()` to find `/sys/class/net/*/address` files on Linux, `glob()` encountered errors, returning `false` instead of an empty array, causing `array_map()` to emit warnings since its second parameter was not an array; this release gracefully handles cases where `glob()` returns `false` [#203](https://github.com/ramsey/uuid/issues/203)
+  * Fixed an off-by-one error in `DefaultTimeGenerator` and switching to `random_int()` from `mt_rand()` for better random numbers [#206](https://github.com/ramsey/uuid/pull/206)
+
+## 3.7.2
+
+_Released: 2018-01-13_
+
+  * On Linux, first check sysfs to determine node identifier; this provides a reliable way to identify the node on Docker images, etc. [#185](https://github.com/ramsey/uuid/pull/185)
+
+## 3.7.1
+
+_Released: 2017-09-22_
+
+  * Use `random_bytes()` when generating random nodes
+  * Set the multicast bit for random nodes, according to RFC 4122, §4.5, [#170](https://github.com/ramsey/uuid/pull/170), [#171](https://github.com/ramsey/uuid/pull/171), [#182](https://github.com/ramsey/uuid/pull/182)
+
+## 3.7.0
+
+_Released: 2017-08-04_
+
+  * Add UUID version constants [#173](https://github.com/ramsey/uuid/issues/173), [#177](https://github.com/ramsey/uuid/pull/177)
+    * `Uuid::UUID_TYPE_TIME`
+    * `Uuid::UUID_TYPE_IDENTIFIER`

+
+## 3.6.0
+
+_Released: 2017-03-18_
+
+  * Add `InvalidUuidStringException`, thrown when attempting to decode an invalid string UUID; this does not introduce any BC issues, since the new exception inherits from the previously used `InvalidArgumentException` [#162](https://github.com/ramsey/uuid/pull/162)
+  * Improve memory usage when generating large quantities of UUIDs (use `str_pad()` and `dechex()` instead of `sprintf()`) [#160](https://github.com/ramsey/uuid/pull/160)
+  * Minor test and documentation updates

+
+## 3.0.0
+
+_Released: 2015-09-28_
+
+The 3.0.0 release represents a significant step for the ramsey/uuid library. While the simple and familiar API used in previous versions remains intact, this release provides greater flexibility to integrators, including the ability to inject your own number generators, UUID codecs, node and time providers, and more.
+
+  * BREAK: The root namespace for this package has changed from "Rhumsaa" to "Ramsey." In most cases, simply making this change in your applications is the only upgrade path you will need. Everything else should work as expected.
+  * BREAK: The UUID [Doctrine field type](http://doctrine-dbal.readthedocs.org/en/latest/reference/types.html) has been moved to [ramsey/uuid-doctrine](https://github.com/ramsey/uuid-doctrine).
+  * BREAK: The `uuid` console application has been moved to [ramsey/uuid-console](https://github.com/ramsey/uuid-console).
+  * BREAK: The `Uuid::VERSION` package version constant has been removed.
+  * See also the release notes for [3.0.0-alpha1][300-alpha1], [3.0.0-alpha2][300-alpha2], [3.0.0-alpha3][300-alpha3], and [3.0.0-beta1][300-beta1].

+
+## 3.0.0-beta1
+
+_Released: 2015-08-31_
+
+  * Improve GUID support to ensure that:
+    * On little endian (LE) architectures, the byte order of the first three fields is LE.
+    * On big endian (BE) architectures, it is the same as a GUID.
+    * String representation is always the same.
+  * Fix exception message for `DegradedNumberConverter::fromHex()`.
+  * Add Scrutinizer configuration to run code-quality builds through Scrutinizer.
+  * Auto-fix Scrutinizer issues.
+  * Fix support URLs in composer.json to point to the correct GitHub repository.
+
+## 3.0.0-alpha3
+
+_Released: 2015-07-28_
+
+  * Time generator improvements:
+    * Enabled use of custom TimeGenerator implementations.
+      * BREAK: Removed now unnecessary `timeConverter` and `timeProvider` properties, setters, and getters in both `FeatureSet` and `UuidFactory` as those are now exclusively used by the default `TimeGenerator`.
+      * Added a `setTimeGenerator` method on `UuidFactory` to override the default time generator.
+    * Add option to enable `PeclUuidTimeGenerator` via `FeatureSet`.
+
+## 3.0.0-alpha2
+
+_Released: 2015-07-28_
+
+  * BREAK: Removed `PeclUuidFactory` in favor of using pecl-uuid with generators.
+  * NEW: Refactored time-based (version 1) UUIDs into a `TimeGeneratorInterface` to allow for other sources to generate version 1 UUIDs in this library.
+  * NEW: Added `PeclUuidTimeGenerator` and `PeclUuidRandomGenerator` for creating version 1 or version 4 UUIDs using the pecl-uuid extension.
+  * NEW: Add `RandomBytesGenerator` for use with PHP 7. ramsey/uuid will default to use this generator when running on PHP 7.
+  * `RandomLibAdapter` now defaults to a medium-strength generator with [ircmaxell/random-lib](https://github.com/ircmaxell/RandomLib). This is configurable, so other generator strengths may be used.
+  * Migrated to the Travis CI container-based infrastructure for builds.
+  * Documentation updates and corrections.
+
+## 3.0.0-alpha1
+
+_Released: 2015-07-16_
+
+  * BREAK: The root namespace for this package has changed from "Rhumsaa" to "Ramsey." In most cases, simply making this change in your applications is the only upgrade path you will need. Everything else should work as expected.
+  * BREAK: The UUID [Doctrine field type](http://doctrine-dbal.readthedocs.org/en/latest/reference/types.html) has been moved to [ramsey/uuid-doctrine](https://github.com/ramsey/uuid-doctrine).
+  * BREAK: The `uuid` console application has been moved to [ramsey/uuid-console](https://github.com/ramsey/uuid-console).
+  * BREAK: The `Uuid::VERSION` package version constant has been removed.
+  * NEW: The `Uuid` class is no longer marked as `final`. Everything is now based around interfaces and factories, allowing you to use this package as a base to implement other kinds of UUIDs with different dependencies.
+  * NEW: Through setting dependencies on `UuidFactory` and/or extending `FeatureSet`, you may override any package defaults, injecting your own dependencies.
+  * NEW: For random number generation, in addition to `OpenSslGenerator` (used if `openssl_random_pseudo_bytes()` is present) and the fallback `MtRandGenerator`, you may use the bundled `CombGenerator` for sequential UUIDs or the `RandomLibAdapter` if using [ircmaxell/random-lib](https://github.com/ircmaxell/RandomLib).
+  * NEW: In addition to the default UUID generation, this library also supports GUID generation by configuring a `FeatureSet` to use GUIDs.
+  * NEW: While the interface to create UUIDs hasn't changed, if using this package on a 32-bit system, you will now receive an object of type `DegradedUuid` (which extends `Uuid`, which implements `UuidInterface`).
+  * NEW: All UUIDs are now [JsonSerializable](http://php.net/JsonSerializable).
+
+## 2.9.0
+
+_Released: 2016-03-22_
+
+  * Drop support for OpenSSL in favor of [paragonie/random_compat][]. This addresses and fixes the [collision issue][].

+
+## Reporting Bugs
+
+Bugs are tracked in our project's [issue tracker](https://github.com/ramsey/uuid/issues).
+
+When submitting a bug report, please include enough information for us to reproduce the bug. A good bug report includes the following sections:
+
+* Expected outcome
+* Actual outcome
+* Steps to reproduce, including sample code
+* Any other information that will help us debug and reproduce the issue, including stack traces, system/environment information, and screenshots

+
+## Fixing Bugs
+
+We welcome pull requests to fix bugs!
+
+If you see a bug report that you'd like to fix, please feel free to do so. Following the directions and guidelines described in the "Adding New Features" section below, you may create bugfix branches and send us pull requests.
+
+## Adding New Features
+
+If you have an idea for a new feature, it's a good idea to check out our [issues](https://github.com/ramsey/uuid/issues) or active [pull requests](https://github.com/ramsey/uuid/pulls) first to see if the feature is already being worked on. If not, feel free to submit an issue first, asking whether the feature is beneficial to the project. This will save you from doing a lot of development work only to have your feature rejected. We don't enjoy rejecting your hard work, but some features just don't fit with the goals of the project.
+
+When you do begin working on your feature, here are some guidelines to consider:
+
+* Your pull request description should clearly detail the changes you have made. We will use this description to add to our CHANGELOG. If there is no description or it does not adequately describe your feature, we will ask you to update the description.
+* We following the **[PSR-2 coding standard](http://www.php-fig.org/psr/psr-2/)**. Please ensure your code does, too.
+* Please **write tests** for any new features you add.
+* Please **ensure that tests pass** before submitting your pull request. We have Travis CI automatically running tests for pull requests. However, running the tests locally will help save time.
+* **Use topic/feature branches.** Please do not ask us to pull from your master branch.
+* **Submit one feature per pull request.** If you have multiple features you wish to submit, please break them up into separate pull requests.
+* **Send coherent history**. Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please squash them before submitting.
+
+## Running Tests
+
+The following tests must pass before we will accept a pull request. If any of these do not pass, it will result in a complete build failure. Before you can run these, be sure to `composer install`.
+
+```
+composer test
+```
+
+### Locally Test With Emulated MIPS Architecture
+
+The following commands use [Vagrant](https://www.vagrantup.com/) to start an Ubuntu VM, install necessary dependencies, and then run the `tools/run-tests.sh` script that will download a Docker image emulating the MIPS architecture. This is especially helpful for testing UUID generation in a big-endian environment.
+
+```
+vagrant init ubuntu/trusty64
+vagrant up

+_NOTICE: Formerly known as `rhumsaa/uuid`, The package and namespace names have changed to `ramsey/uuid` and `Ramsey\Uuid`, respectively._

+
+ramsey/uuid is a PHP 5.4+ library for generating and working with [RFC 4122][rfc4122] version 1, 3, 4, and 5 universally unique identifiers (UUID).
+
+This project adheres to a [Contributor Code of Conduct][conduct]. By participating in this project and its community, you are expected to uphold this code.
+
+
+## About
+
+From [Wikipedia](http://en.wikipedia.org/wiki/Universally_unique_identifier):
+
+> The intent of UUIDs is to enable distributed systems to uniquely identify information without significant central coordination. In this context the word unique should be taken to mean "practically unique" rather than "guaranteed unique". Since the identifiers have a finite size, it is possible for two differing items to share the same identifier. The identifier size and generation process need to be selected so as to make this sufficiently improbable in practice. Anyone can create a UUID and use it to identify something with reasonable confidence that the same identifier will never be unintentionally created by anyone to identify something else. Information labeled with UUIDs can therefore be later combined into a single database without needing to resolve identifier (ID) conflicts.
+
+Much inspiration for this library came from the [Java][javauuid] and [Python][pyuuid] UUID libraries.
+
+
+## Installation
+
+The preferred method of installation is via [Packagist][] and [Composer][]. Run the following command to install the package and add it as a requirement to your project's `composer.json`:
+
+```bash
+composer require ramsey/uuid
+```
+
+
+## Upgrading from 2.x to 3.x
+
+While we have made significant internal changes to the library, we have made every effort to ensure a seamless upgrade path from the 2.x series of this library to 3.x.
+
+One major breaking change is the transition from the `Rhumsaa` root namespace to `Ramsey`. In most cases, all you will need is to change the namespace to `Ramsey` in your code, and everything will "just work."
+
+Here are full details on the breaking changes to the public API of this library:
+
+1. All namespace references of `Rhumsaa` have changed to `Ramsey`. Simply change the namespace to `Ramsey` in your code and everything should work.
+2. The console application has moved to [ramsey/uuid-console](https://packagist.org/packages/ramsey/uuid-console). If using the console functionality, use Composer to require `ramsey/uuid-console`.
+3. The Doctrine field type mapping has moved to [ramsey/uuid-doctrine](https://packagist.org/packages/ramsey/uuid-doctrine). If using the Doctrine functionality, use Composer to require `ramsey/uuid-doctrine`.
+
+
+## What to do if you see a "rhumsaa/uuid is abandoned" message
+
+When installing your project's dependencies using Composer, you might see the following message:
+
+```
+Package rhumsaa/uuid is abandoned, you should avoid using it. Use ramsey/uuid instead.
+```
+
+Don't panic. Simply execute the following commands with Composer:
+
+``` bash
+composer remove rhumsaa/uuid
+composer require ramsey/uuid=^2.9
+```
+
+After doing so, you will have the latest ramsey/uuid package in the 2.x series, and there will be no need to modify any code; the namespace in the 2.x series is still `Rhumsaa`.
+
+
+## Requirements
+
+Some methods in this library have requirements due to integer size restrictions on 32-bit and 64-bit builds of PHP. A 64-bit build of PHP and the [Moontoast\Math][] library are recommended. However, this library is designed to work on 32-bit builds of PHP without Moontoast\Math, with some degraded functionality. Please check the API documentation for more information.
+
+If a particular requirement is not present, then an `UnsatisfiedDependencyException` is thrown, allowing one to catch a bad call in an environment where the call is not supported and gracefully degrade.
+
+
+## API documentation
+
+The [latest class API documentation][apidocs] is available online.
+
+This project uses [ApiGen](http://apigen.org/) to generate this documentation. To generate the documentation on your own, install dev dependencies and run the following command from the root of the project:
+
+```
+composer build-docs
+```
+
+This will generate documentation in the `build/apidocs/` folder.
+
+
+## Examples
+
+See the [cookbook on the wiki][wiki-cookbook] for more examples and approaches to specific use-cases.
+
+```php
+<?php
+require 'vendor/autoload.php';
+
+use Ramsey\Uuid\Uuid;
+use Ramsey\Uuid\Exception\UnsatisfiedDependencyException;
+
+try {
+
+    // Generate a version 1 (time-based) UUID object
+    $uuid1 = Uuid::uuid1();
+    echo $uuid1->toString() . "\n"; // i.e. e4eaaaf2-d142-11e1-b3e4-080027620cdd
+
+    // Generate a version 3 (name-based and hashed with MD5) UUID object
+    $uuid3 = Uuid::uuid3(Uuid::NAMESPACE_DNS, 'php.net');
+    echo $uuid3->toString() . "\n"; // i.e. 11a38b9a-b3da-360f-9353-a5a725514269
+
+    // Generate a version 4 (random) UUID object
+    $uuid4 = Uuid::uuid4();
+    echo $uuid4->toString() . "\n"; // i.e. 25769c6c-d34d-4bfe-ba98-e0ee856f3e7a
+
+    // Generate a version 5 (name-based and hashed with SHA1) UUID object
+    $uuid5 = Uuid::uuid5(Uuid::NAMESPACE_DNS, 'php.net');
+    echo $uuid5->toString() . "\n"; // i.e. c4a760a8-dbcf-5254-a0d9-6a4474bd1b62
+
+} catch (UnsatisfiedDependencyException $e) {
+
+    // Some dependency was not met. Either the method cannot be called on a
+    // 32-bit system, or it can, but it relies on Moontoast\Math to be present.
+    echo 'Caught exception: ' . $e->getMessage() . "\n";
+
+}
+```

+
+## Intro
+
+Phinx makes it ridiculously easy to manage the database migrations for your PHP app. In less than 5 minutes, you can install Phinx and create your first database migration. Phinx is just about migrations without all the bloat of a database ORM system or framework.
+
+**Check out https://book.cakephp.org/3.0/en/phinx.html ([EN](https://book.cakephp.org/3.0/en/phinx.html), [ZH](https://tsy12321.gitbooks.io/phinx-doc/)) for the comprehensive documentation.**

+
+### Features
+
+* Write database migrations using database agnostic PHP code.
+* Migrate up and down.
+* Migrate on deployment.
+* Seed data after database creation.
+* Get going in less than 5 minutes.
+* Stop worrying about the state of your database.
+* Take advantage of SCM features such as branching.
+* Integrate with any app.
+
+### Supported Adapters
+
+Phinx natively supports the following database adapters:
+
+* MySQL
+* PostgreSQL
+* SQLite
+* Microsoft SQL Server
+
+## Install & Run

+    php composer.phar install
+    ```
+
+1. Execute Phinx:
+
+    ```
+    php vendor/bin/phinx
+    ```
+
+### As a Phar
+
+You can also use the Box application to build Phinx as a Phar archive (https://box-project.github.io/box2/).
+
+1. Clone Phinx from GitHub
+
+    ```
+    git clone https://github.com/cakephp/phinx.git
+    cd phinx
+    ```
+
+1. Install Composer
+
+    ```
+    curl -s https://getcomposer.org/installer | php
+    ```
+
+1. Install the Phinx dependencies
+
+    ```
+    php composer.phar install
+    ```
+
+1. Install Box:
+
+    ```
+    curl -LSs https://box-project.github.io/box2/installer.php | php
+    ```
+
+1. Create a Phar archive
+
+    ```
+    php box.phar build
+    ```

+# Upgrading Phinx to 0.8
+
+* Phinx 0.8 allows for `phinx rollback` and `phinx status` to operate on migrations in reverse execution order,
+rather than reverse creation order. To achieve this new ordering, you will need to add a new entry in your
+`phinx.yml` file (or equivalent).  
+  
+  The setting is called `version_order` and supports 2 values:
+  * `creation` - this is the default value and matches the standard behaviour of executing rollbacks in the
+  reverse order based upon the creation datetime (also known as `version`).
+  * `execution` - this is the new value and will execute rollbacks in the reverse order in which they were
+  applied.
+
+  This feature will be of most importance when development of migrations takes place in different branches
+  within a codebase and are merged in to master for deployment. It will no longer matter when the migrations
+  were created if it becomes necessary to rollback the migrations.

+
+# Comparator
+
+This component provides the functionality to compare PHP values for equality.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/comparator
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/comparator
+
+## Usage
+
+```php
+<?php
+use SebastianBergmann\Comparator\Factory;
+use SebastianBergmann\Comparator\ComparisonFailure;
+
+$date1 = new DateTime('2013-03-29 04:13:35', new DateTimeZone('America/New_York'));
+$date2 = new DateTime('2013-03-29 03:13:35', new DateTimeZone('America/Chicago'));
+
+$factory = new Factory;
+$comparator = $factory->getComparatorFor($date1, $date2);
+
+try {
+    $comparator->assertEquals($date1, $date2);
+    print "Dates match";
+}
+
+catch (ComparisonFailure $failure) {
+    print "Dates don't match";
+}
+```

+# sebastian/diff
+
+Diff implementation for PHP, factored out of PHPUnit into a stand-alone component.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/diff
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/diff
+
+### Usage
+
+The `Differ` class can be used to generate a textual representation of the difference between two strings:
+
+```php
+use SebastianBergmann\Diff\Differ;
+
+$differ = new Differ;
+print $differ->diff('foo', 'bar');
+```
+
+The code above yields the output below:
+
+    --- Original
+    +++ New
+    @@ @@
+    -foo
+    +bar
+
+The `Parser` class can be used to parse a unified diff into an object graph:
+
+```php
+use SebastianBergmann\Diff\Parser;
+use SebastianBergmann\Git;
+
+$git = new Git('/usr/local/src/money');
+
+$diff = $git->getDiff(
+  '948a1a07768d8edd10dcefa8315c1cbeffb31833',
+  'c07a373d2399f3e686234c4f7f088d635eb9641b'
+);
+
+$parser = new Parser;
+
+print_r($parser->parse($diff));
+```
+
+The code above yields the output below:

+# Environment
+
+This component provides functionality that helps writing PHP code that has runtime-specific (PHP / HHVM) execution paths.
+
+[![Latest Stable Version](https://poser.pugx.org/sebastian/environment/v/stable.png)](https://packagist.org/packages/sebastian/environment)
+[![Build Status](https://travis-ci.org/sebastianbergmann/environment.png?branch=master)](https://travis-ci.org/sebastianbergmann/environment)
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/environment
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/environment
+
+## Usage
+
+```php
+<?php
+use SebastianBergmann\Environment\Runtime;
+
+$runtime = new Runtime;
+
+var_dump($runtime->getNameWithVersion());
+var_dump($runtime->getName());
+var_dump($runtime->getVersion());
+var_dump($runtime->getBinary());
+var_dump($runtime->isHHVM());
+var_dump($runtime->isPHP());
+var_dump($runtime->hasXdebug());
+var_dump($runtime->canCollectCodeCoverage());
+```

+[![Build Status](https://secure.travis-ci.org/sebastianbergmann/exporter.png?branch=master)](https://travis-ci.org/sebastianbergmann/exporter)
+
+This component provides the functionality to export PHP variables for visualization.
+
+## Usage
+
+Exporting:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+/*
+Exception Object &0000000078de0f0d000000002003a261 (
+    'message' => ''
+    'string' => ''
+    'code' => 0
+    'file' => '/home/sebastianbergmann/test.php'
+    'line' => 34
+    'trace' => Array &0 ()
+    'previous' => null
+)
+*/
+
+print $exporter->export(new Exception);
+```
+
+## Data Types
+
+Exporting simple types:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+// 46
+print $exporter->export(46);
+
+// 4.0
+print $exporter->export(4.0);
+
+// 'hello, world!'
+print $exporter->export('hello, world!');
+
+// false
+print $exporter->export(false);
+
+// NAN
+print $exporter->export(acos(8));
+
+// -INF
+print $exporter->export(log(0));
+
+// null
+print $exporter->export(null);
+
+// resource(13) of type (stream)
+print $exporter->export(fopen('php://stderr', 'w'));
+
+// Binary String: 0x000102030405
+print $exporter->export(chr(0) . chr(1) . chr(2) . chr(3) . chr(4) . chr(5));
+```
+
+Exporting complex types:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+/*
+Array &0 (
+    0 => Array &1 (
+        0 => 1
+        1 => 2
+        2 => 3
+    )
+    1 => Array &2 (
+        0 => ''
+        1 => 0
+        2 => false
+    )
+)
+*/
+
+print $exporter->export(array(array(1,2,3), array("",0,FALSE)));
+
+/*
+Array &0 (
+    'self' => Array &1 (
+        'self' => Array &1
+    )
+)
+*/
+
+$array = array();
+$array['self'] = &$array;
+print $exporter->export($array);
+
+/*
+stdClass Object &0000000003a66dcc0000000025e723e2 (
+    'self' => stdClass Object &0000000003a66dcc0000000025e723e2
+)
+*/
+
+$obj = new stdClass();
+$obj->self = $obj;
+print $exporter->export($obj);
+```
+
+Compact exports:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+// Array ()
+print $exporter->shortenedExport(array());
+
+// Array (...)
+print $exporter->shortenedExport(array(1,2,3,4,5));
+
+// stdClass Object ()
+print $exporter->shortenedExport(new stdClass);
+
+// Exception Object (...)
+print $exporter->shortenedExport(new Exception);
+
+// this\nis\na\nsuper\nlong\nstring\nt...\nspace
+print $exporter->shortenedExport(
+<<<LONG_STRING
+this
+is
+a
+super
+long
+string
+that
+wraps
+a
+lot
+and
+eats
+up
+a
+lot
+of
+space
+LONG_STRING
+);
+```
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/exporter
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/exporter

+# GlobalState
+
+Snapshotting of global state, factored out of PHPUnit into a stand-alone component.
+
+[![Build Status](https://travis-ci.org/sebastianbergmann/global-state.svg?branch=master)](https://travis-ci.org/sebastianbergmann/global-state)
+
+## Installation
+
+To add this package as a local, per-project dependency to your project, simply add a dependency on `sebastian/global-state` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on GlobalState:
+
+    {
+        "require": {
+            "sebastian/global-state": "1.0.*"
+        }
+    }

+# Version
+
+**Version** is a library that helps with managing the version number of Git-hosted PHP projects.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/version
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/version
+
+## Usage
+
+The constructor of the `SebastianBergmann\Version` class expects two parameters:
+
+* `$release` is the version number of the latest release (`X.Y.Z`, for instance) or the name of the release series (`X.Y`) when no release has been made from that branch / for that release series yet.
+* `$path` is the path to the directory (or a subdirectory thereof) where the sourcecode of the project can be found. Simply passing `__DIR__` here usually suffices.
+
+Apart from the constructor, the `SebastianBergmann\Version` class has a single public method: `getVersion()`.
+
+Here is a contrived example that shows the basic usage:
+
+    <?php
+    $version = new SebastianBergmann\Version(
+      '3.7.10', '/usr/local/src/phpunit'
+    );
+
+    var_dump($version->getVersion());
+    ?>
+
+    string(18) "3.7.10-17-g00f3408"
+
+When a new release is prepared, the string that is passed to the constructor as the first argument needs to be updated.
+
+### How SebastianBergmann\Version::getVersion() works
+
+* If `$path` is not (part of) a Git repository and `$release` is in `X.Y.Z` format then `$release` is returned as-is.
+* If `$path` is not (part of) a Git repository and `$release` is in `X.Y` format then `$release` is returned suffixed with `-dev`.
+* If `$path` is (part of) a Git repository and `$release` is in `X.Y.Z` format then the output of `git describe --tags` is returned as-is.
+* If `$path` is (part of) a Git repository and `$release` is in `X.Y` format then a string is returned that begins with `X.Y` and ends with information from `git describe --tags`.

+# Slim Framework Twig View
+
+[![Build Status](https://travis-ci.org/slimphp/Twig-View.svg?branch=master)](https://travis-ci.org/slimphp/Twig-View)
+
+This is a Slim Framework view helper built on top of the Twig templating component. You can use this component to create and render templates in your Slim Framework application. It works with Twig 1.18+ (PHP5.5+) and with Twig 2 (PHP7).
+
+## Install
+
+Via [Composer](https://getcomposer.org/)
+
+```bash
+$ composer require slim/twig-view
+```
+
+Requires Slim Framework 3 and PHP 5.5.0 or newer.
+
+## Usage
+
+```php
+// Create Slim app
+$app = new \Slim\App();
+
+// Fetch DI Container
+$container = $app->getContainer();
+
+// Register Twig View helper
+$container['view'] = function ($c) {
+    $view = new \Slim\Views\Twig('path/to/templates', [
+        'cache' => 'path/to/cache'
+    ]);
+    
+    // Instantiate and add Slim specific extension
+    $basePath = rtrim(str_ireplace('index.php', '', $c['request']->getUri()->getBasePath()), '/');
+    $view->addExtension(new \Slim\Views\TwigExtension($c['router'], $basePath));
+
+    return $view;
+};
+
+// Define named route
+$app->get('/hello/{name}', function ($request, $response, $args) {
+    return $this->view->render($response, 'profile.html', [
+        'name' => $args['name']
+    ]);
+})->setName('profile');
+
+// Render from string
+$app->get('/hi/{name}', function ($request, $response, $args) {
+    $str = $this->view->fetchFromString('<p>Hi, my name is {{ name }}.</p>', [
+        'name' => $args['name']
+    ]);
+    $response->getBody()->write($str);
+    return $response;
+});
+
+// Run app
+$app->run();
+```
+
+## Custom template functions
+
+`TwigExtension` provides these functions to your Twig templates:
+
+* `path_for()` - returns the URL for a given route.
+* `base_url()` - returns the `Uri` object's base URL.
+* `is_current_path()` - returns true is the provided route name and parameters are valid for the current path.
+* `current_path()` - renders the current path, with or without the query string.
+
+
+You can use `path_for` to generate complete URLs to any Slim application named route and use `is_current_path` to determine if you need to mark a link as active as shown in this example Twig template:
+
+    {% extends "layout.html" %}
+
+    {% block body %}
+    <h1>User List</h1>
+    <ul>
+        <li><a href="{{ path_for('profile', { 'name': 'josh' }) }}" {% if is_current_path('profle', { 'name': 'josh' }) %}class="active"{% endif %}>Josh</a></li>
+        <li><a href="{{ path_for('profile', { 'name': 'andrew' }) }}">Andrew</a></li>
+    </ul>
+    {% endblock %}
+
+
+## Testing
+
+```bash
+phpunit
+```

+Message Headers
+===============
+
+Sometimes you'll want to add your own headers to a message or modify/remove
+headers that are already present. You work with the message's HeaderSet to do
+this.
+
+Header Basics
+-------------
+
+All MIME entities in Swift Mailer -- including the message itself --
+store their headers in a single object called a HeaderSet. This HeaderSet is
+retrieved with the ``getHeaders()`` method.
+
+As mentioned in the previous chapter, everything that forms a part of a message
+in Swift Mailer is a MIME entity that is represented by an instance of
+``Swift_Mime_MimeEntity``. This includes -- most notably -- the message object
+itself, attachments, MIME parts and embedded images. Each of these MIME entities
+consists of a body and a set of headers that describe the body.
+
+For all of the "standard" headers in these MIME entities, such as the
+``Content-Type``, there are named methods for working with them, such as
+``setContentType()`` and ``getContentType()``. This is because headers are a
+moderately complex area of the library. Each header has a slightly different
+required structure that it must meet in order to comply with the standards that
+govern email (and that are checked by spam blockers etc).
+
+You fetch the HeaderSet from a MIME entity like so:
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance();
+
+    // Fetch the HeaderSet from a Message object
+    $headers = $message->getHeaders();
+
+    $attachment = Swift_Attachment::fromPath('document.pdf');
+
+    // Fetch the HeaderSet from an attachment object
+    $headers = $attachment->getHeaders();
+
+The job of the HeaderSet is to contain and manage instances of Header objects.
+Depending upon the MIME entity the HeaderSet came from, the contents of the
+HeaderSet will be different, since an attachment for example has a different
+set of headers to those in a message.
+
+You can find out what the HeaderSet contains with a quick loop, dumping out
+the names of the headers:
+
+.. code-block:: php
+
+    foreach ($headers->getAll() as $header) {
+      printf("%s<br />\n", $header->getFieldName());
+    }
+
+    /*
+    Content-Transfer-Encoding
+    Content-Type
+    MIME-Version
+    Date
+    Message-ID
+    From
+    Subject
+    To
+    */
+
+You can also dump out the rendered HeaderSet by calling its ``toString()``
+method:
+
+.. code-block:: php
+
+    echo $headers->toString();
+
+    /*
+    Message-ID: <1234869991.499a9ee7f1d5e@swift.generated>
+    Date: Tue, 17 Feb 2009 22:26:31 +1100
+    Subject: Awesome subject!
+    From: sender@example.org
+    To: recipient@example.org
+    MIME-Version: 1.0
+    Content-Type: text/plain; charset=utf-8
+    Content-Transfer-Encoding: quoted-printable
+    */
+
+Where the complexity comes in is when you want to modify an existing header.
+This complexity comes from the fact that each header can be of a slightly
+different type (such as a Date header, or a header that contains email
+addresses, or a header that has key-value parameters on it!). Each header in the
+HeaderSet is an instance of ``Swift_Mime_Header``. They all have common
+functionality, but knowing exactly what type of header you're working with will
+allow you a little more control.
+
+You can determine the type of header by comparing the return value of its
+``getFieldType()`` method with the constants ``TYPE_TEXT``,
+``TYPE_PARAMETERIZED``, ``TYPE_DATE``, ``TYPE_MAILBOX``, ``TYPE_ID`` and
+``TYPE_PATH`` which are defined in ``Swift_Mime_Header``.
+
+
+.. code-block:: php
+
+    foreach ($headers->getAll() as $header) {
+      switch ($header->getFieldType()) {
+        case Swift_Mime_Header::TYPE_TEXT: $type = 'text';
+          break;
+        case Swift_Mime_Header::TYPE_PARAMETERIZED: $type = 'parameterized';
+          break;
+        case Swift_Mime_Header::TYPE_MAILBOX: $type = 'mailbox';
+          break;
+        case Swift_Mime_Header::TYPE_DATE: $type = 'date';
+          break;
+        case Swift_Mime_Header::TYPE_ID: $type = 'ID';
+          break;
+        case Swift_Mime_Header::TYPE_PATH: $type = 'path';
+          break;
+      }
+      printf("%s: is a %s header<br />\n", $header->getFieldName(), $type);
+    }
+
+    /*
+    Content-Transfer-Encoding: is a text header
+    Content-Type: is a parameterized header
+    MIME-Version: is a text header
+    Date: is a date header
+    Message-ID: is a ID header
+    From: is a mailbox header
+    Subject: is a text header
+    To: is a mailbox header
+    */
+
+Headers can be removed from the set, modified within the set, or added to the
+set.
+
+The following sections show you how to work with the HeaderSet and explain the
+details of each implementation of ``Swift_Mime_Header`` that may
+exist within the HeaderSet.
+
+Header Types
+------------
+
+Because all headers are modeled on different data (dates, addresses, text!)
+there are different types of Header in Swift Mailer. Swift Mailer attempts to
+categorize all possible MIME headers into more general groups, defined by a
+small number of classes.
+
+Text Headers
+~~~~~~~~~~~~
+
+Text headers are the simplest type of Header. They contain textual information
+with no special information included within it -- for example the Subject
+header in a message.
+
+There's nothing particularly interesting about a text header, though it is
+probably the one you'd opt to use if you need to add a custom header to a
+message. It represents text just like you'd think it does. If the text
+contains characters that are not permitted in a message header (such as new
+lines, or non-ascii characters) then the header takes care of encoding the
+text so that it can be used.
+
+No header -- including text headers -- in Swift Mailer is vulnerable to
+header-injection attacks. Swift Mailer breaks any attempt at header injection by
+encoding the dangerous data into a non-dangerous form.
+
+It's easy to add a new text header to a HeaderSet. You do this by calling the
+HeaderSet's ``addTextHeader()`` method.
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance();
+
+    $headers = $message->getHeaders();
+
+    $headers->addTextHeader('Your-Header-Name', 'the header value');
+
+Changing the value of an existing text header is done by calling it's
+``setValue()`` method.
+
+.. code-block:: php
+
+    $subject = $message->getHeaders()->get('Subject');
+
+    $subject->setValue('new subject');
+
+When output via ``toString()``, a text header produces something like the
+following:
+
+.. code-block:: php
+
+    $subject = $message->getHeaders()->get('Subject');
+
+    $subject->setValue('amazing subject line');
+
+    echo $subject->toString();
+
+    /*
+
+    Subject: amazing subject line
+
+    */
+
+If the header contains any characters that are outside of the US-ASCII range
+however, they will be encoded. This is nothing to be concerned about since
+mail clients will decode them back.
+
+.. code-block:: php
+
+    $subject = $message->getHeaders()->get('Subject');
+
+    $subject->setValue('contains – dash');
+
+    echo $subject->toString();
+
+    /*
+
+    Subject: contains =?utf-8?Q?=E2=80=93?= dash
+
+    */
+
+Parameterized Headers
+~~~~~~~~~~~~~~~~~~~~~
+
+Parameterized headers are text headers that contain key-value parameters
+following the textual content. The Content-Type header of a message is a
+parameterized header since it contains charset information after the content
+type.
+
+The parameterized header type is a special type of text header. It extends the
+text header by allowing additional information to follow it. All of the methods
+from text headers are available in addition to the methods described here.
+
+Adding a parameterized header to a HeaderSet is done by using the
+``addParameterizedHeader()`` method which takes a text value like
+``addTextHeader()`` but it also accepts an associative array of
+key-value parameters.
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance();
+
+    $headers = $message->getHeaders();
+
+    $headers->addParameterizedHeader(
+      'Header-Name', 'header value',
+      array('foo' => 'bar')
+      );
+
+To change the text value of the header, call it's ``setValue()`` method just as
+you do with text headers.
+
+To change the parameters in the header, call the header's ``setParameters()``
+method or the ``setParameter()`` method (note the pluralization).
+
+.. code-block:: php
+
+    $type = $message->getHeaders()->get('Content-Type');
+
+    // setParameters() takes an associative array
+    $type->setParameters(array(
+      'name' => 'file.txt',
+      'charset' => 'iso-8859-1'
+      ));
+
+    // setParameter() takes two args for $key and $value
+    $type->setParameter('charset', 'iso-8859-1');
+
+When output via ``toString()``, a parameterized header produces something like
+the following:
+
+.. code-block:: php
+
+    $type = $message->getHeaders()->get('Content-Type');
+
+    $type->setValue('text/html');
+    $type->setParameter('charset', 'utf-8');
+
+    echo $type->toString();
+
+    /*
+
+    Content-Type: text/html; charset=utf-8
+
+    */
+
+If the header contains any characters that are outside of the US-ASCII range
+however, they will be encoded, just like they are for text headers. This is
+nothing to be concerned about since mail clients will decode them back.
+Likewise, if the parameters contain any non-ascii characters they will be
+encoded so that they can be transmitted safely.
+
+.. code-block:: php
+
+    $attachment = Swift_Attachment::newInstance();
+
+    $disp = $attachment->getHeaders()->get('Content-Disposition');
+
+    $disp->setValue('attachment');
+    $disp->setParameter('filename', 'report–may.pdf');
+
+    echo $disp->toString();
+
+    /*
+
+    Content-Disposition: attachment; filename*=utf-8''report%E2%80%93may.pdf
+
+    */
+
+Date Headers
+~~~~~~~~~~~~

+Date headers contains an RFC 2822 formatted date (i.e. what PHP's ``date('r')``
+returns). They are used anywhere a date or time is needed to be presented as a
+message header.
+
+The data on which a date header is modeled is simply a UNIX timestamp such as
+that returned by ``time()`` or ``strtotime()``.  The timestamp is used to create
+a correctly structured RFC 2822 formatted date such as
+``Tue, 17 Feb 2009 22:26:31 +1100``.
+
+The obvious place this header type is used is in the ``Date:`` header of the
+message itself.
+
+It's easy to add a new date header to a HeaderSet.  You do this by calling
+the HeaderSet's ``addDateHeader()`` method.
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance();
+
+    $headers = $message->getHeaders();
+
+    $headers->addDateHeader('Your-Header-Name', strtotime('3 days ago'));
+
+Changing the value of an existing date header is done by calling it's
+``setTimestamp()`` method.
+
+.. code-block:: php
+
+    $date = $message->getHeaders()->get('Date');
+
+    $date->setTimestamp(time());
+
+When output via ``toString()``, a date header produces something like the
+following:
+
+.. code-block:: php
+
+    $date = $message->getHeaders()->get('Date');
+
+    echo $date->toString();
+
+    /*
+
+    Date: Wed, 18 Feb 2009 13:35:02 +1100
+
+    */
+
+Mailbox (e-mail address) Headers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Mailbox headers contain one or more email addresses, possibly with
+personalized names attached to them. The data on which they are modeled is
+represented by an associative array of email addresses and names.
+
+Mailbox headers are probably the most complex header type to understand in
+Swift Mailer because they accept their input as an array which can take various
+forms, as described in the previous chapter.
+
+All of the headers that contain e-mail addresses in a message -- with the
+exception of ``Return-Path:`` which has a stricter syntax -- use this header
+type. That is, ``To:``, ``From:`` etc.
+
+You add a new mailbox header to a HeaderSet by calling the HeaderSet's
+``addMailboxHeader()`` method.
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance();
+
+    $headers = $message->getHeaders();
+
+    $headers->addMailboxHeader('Your-Header-Name', array(
+      'person1@example.org' => 'Person Name One',
+      'person2@example.org',
+      'person3@example.org',
+      'person4@example.org' => 'Another named person'
+      ));
+
+Changing the value of an existing mailbox header is done by calling it's
+``setNameAddresses()`` method.
+
+.. code-block:: php
+
+    $to = $message->getHeaders()->get('To');
+
+    $to->setNameAddresses(array(
+      'joe@example.org' => 'Joe Bloggs',
+      'john@example.org' => 'John Doe',
+      'no-name@example.org'
+      ));
+
+If you don't wish to concern yourself with the complicated accepted input
+formats accepted by ``setNameAddresses()`` as described in the previous chapter
+and you only want to set one or more addresses (not names) then you can just
+use the ``setAddresses()`` method instead.
+
+.. code-block:: php
+
+    $to = $message->getHeaders()->get('To');
+
+    $to->setAddresses(array(
+      'joe@example.org',
+      'john@example.org',
+      'no-name@example.org'
+      ));
+
+.. note::
+
+    Both methods will accept the above input format in practice.
+
+If all you want to do is set a single address in the header, you can use a
+string as the input parameter to ``setAddresses()`` and/or
+``setNameAddresses()``.
+
+.. code-block:: php
+
+    $to = $message->getHeaders()->get('To');
+
+    $to->setAddresses('joe-bloggs@example.org');
+
+When output via ``toString()``, a mailbox header produces something like the
+following:
+
+.. code-block:: php
+
+    $to = $message->getHeaders()->get('To');
+
+    $to->setNameAddresses(array(
+      'person1@example.org' => 'Name of Person',
+      'person2@example.org',
+      'person3@example.org' => 'Another Person'
+    ));
+
+    echo $to->toString();
+
+    /*
+
+    To: Name of Person <person1@example.org>, person2@example.org, Another Person
+     <person3@example.org>
+
+    */
+
+ID Headers
+~~~~~~~~~~
+
+ID headers contain identifiers for the entity (or the message). The most
+notable ID header is the Message-ID header on the message itself.
+
+An ID that exists inside an ID header looks more-or-less less like an email
+address.  For example, ``<1234955437.499becad62ec2@example.org>``.
+The part to the left of the @ sign is usually unique, based on the current time
+and some random factor. The part on the right is usually a domain name.
+
+Any ID passed to the header's ``setId()`` method absolutely MUST conform to
+this structure, otherwise you'll get an Exception thrown at you by Swift Mailer
+(a ``Swift_RfcComplianceException``).  This is to ensure that the generated
+email complies with relevant RFC documents and therefore is less likely to be
+blocked as spam.
+
+It's easy to add a new ID header to a HeaderSet.  You do this by calling
+the HeaderSet's ``addIdHeader()`` method.
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance();
+
+    $headers = $message->getHeaders();
+
+    $headers->addIdHeader('Your-Header-Name', '123456.unqiue@example.org');
+
+Changing the value of an existing ID header is done by calling its
+``setId()`` method::
+
+    $msgId = $message->getHeaders()->get('Message-ID');
+
+    $msgId->setId(time() . '.' . uniqid('thing') . '@example.org');
+
+When output via ``toString()``, an ID header produces something like the
+following:
+
+.. code-block:: php
+
+    $msgId = $message->getHeaders()->get('Message-ID');
+
+    echo $msgId->toString();
+
+    /*
+
+    Message-ID: <1234955437.499becad62ec2@example.org>
+
+    */
+
+Path Headers
+~~~~~~~~~~~~
+
+Path headers are like very-restricted mailbox headers. They contain a single
+email address with no associated name. The Return-Path header of a message is
+a path header.
+
+You add a new path header to a HeaderSet by calling the HeaderSet's
+``addPathHeader()`` method.
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance();
+
+    $headers = $message->getHeaders();
+
+    $headers->addPathHeader('Your-Header-Name', 'person@example.org');
+
+Changing the value of an existing path header is done by calling its
+``setAddress()`` method.
+
+.. code-block:: php
+
+    $return = $message->getHeaders()->get('Return-Path');
+
+    $return->setAddress('my-address@example.org');
+
+When output via ``toString()``, a path header produces something like the
+following:
+
+.. code-block:: php
+
+    $return = $message->getHeaders()->get('Return-Path');
+
+    $return->setAddress('person@example.org');
+
+    echo $return->toString();
+
+    /*
+
+    Return-Path: <person@example.org>
+
+    */
+
+Header Operations
+-----------------
+
+Working with the headers in a message involves knowing how to use the methods
+on the HeaderSet and on the individual Headers within the HeaderSet.
+
+Adding new Headers
+~~~~~~~~~~~~~~~~~~
+
+New headers can be added to the HeaderSet by using one of the provided
+``add..Header()`` methods.
+
+To add a header to a MIME entity (such as the message):
+
+Get the HeaderSet from the entity by via its ``getHeaders()`` method.
+
+* Add the header to the HeaderSet by calling one of the ``add..Header()``
+  methods.
+
+The added header will appear in the message when it is sent.
+
+.. code-block:: php
+
+    // Adding a custom header to a message
+    $message = Swift_Message::newInstance();
+    $headers = $message->getHeaders();
+    $headers->addTextHeader('X-Mine', 'something here');
+
+    // Adding a custom header to an attachment
+    $attachment = Swift_Attachment::fromPath('/path/to/doc.pdf');
+    $attachment->getHeaders()->addDateHeader('X-Created-Time', time());
+
+Retrieving Headers
+~~~~~~~~~~~~~~~~~~
+
+Headers are retrieved through the HeaderSet's ``get()`` and ``getAll()``
+methods.
+
+To get a header, or several headers from a MIME entity:
+
+* Get the HeaderSet from the entity by via its ``getHeaders()`` method.
+
+* Get the header(s) from the HeaderSet by calling either ``get()`` or
+  ``getAll()``.
+
+When using ``get()`` a single header is returned that matches the name (case
+insensitive) that is passed to it. When using ``getAll()`` with a header name,
+an array of headers with that name are returned. Calling ``getAll()`` with no
+arguments returns an array of all headers present in the entity.
+
+.. note::
+
+    It's valid for some headers to appear more than once in a message (e.g.
+    the Received header). For this reason ``getAll()`` exists to fetch all
+    headers with a specified name. In addition, ``get()`` accepts an optional
+    numerical index, starting from zero to specify which header you want more
+    specifically.
+
+.. note::
+
+    If you want to modify the contents of the header and you don't know for
+    sure what type of header it is then you may need to check the type by
+    calling its ``getFieldType()`` method.
+
+    .. code-block:: php
+
+        $headers = $message->getHeaders();
+
+        // Get the To: header
+        $toHeader = $headers->get('To');
+
+        // Get all headers named "X-Foo"
+        $fooHeaders = $headers->getAll('X-Foo');
+
+        // Get the second header named "X-Foo"
+        $foo = $headers->get('X-Foo', 1);
+
+        // Get all headers that are present
+        $all = $headers->getAll();
+
+Check if a Header Exists
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can check if a named header is present in a HeaderSet by calling its
+``has()`` method.
+
+To check if a header exists:
+
+* Get the HeaderSet from the entity by via its ``getHeaders()`` method.
+
+* Call the HeaderSet's ``has()`` method specifying the header you're looking
+  for.
+
+If the header exists, ``true`` will be returned or ``false`` if not.
+
+.. note::
+
+    It's valid for some headers to appear more than once in a message (e.g.
+    the Received header). For this reason ``has()`` accepts an optional
+    numerical index, starting from zero to specify which header you want to
+    check more specifically.
+
+    .. code-block:: php
+
+        $headers = $message->getHeaders();
+
+        // Check if the To: header exists
+        if ($headers->has('To')) {
+          echo 'To: exists';
+        }
+
+        // Check if an X-Foo header exists twice (i.e. check for the 2nd one)
+        if ($headers->has('X-Foo', 1)) {
+          echo 'Second X-Foo header exists';
+        }
+
+Removing Headers
+~~~~~~~~~~~~~~~~
+
+Removing a Header from the HeaderSet is done by calling the HeaderSet's
+``remove()`` or ``removeAll()`` methods.
+
+To remove an existing header:
+
+* Get the HeaderSet from the entity by via its ``getHeaders()`` method.
+
+* Call the HeaderSet's ``remove()`` or ``removeAll()`` methods specifying the
+  header you want to remove.
+
+When calling ``remove()`` a single header will be removed. When calling
+``removeAll()`` all headers with the given name will be removed. If no headers
+exist with the given name, no errors will occur.
+
+.. note::
+
+    It's valid for some headers to appear more than once in a message (e.g.
+    the Received header). For this reason ``remove()`` accepts an optional
+    numerical index, starting from zero to specify which header you want to
+    check more specifically. For the same reason, ``removeAll()`` exists to
+    remove all headers that have the given name.
+
+    .. code-block:: php
+
+        $headers = $message->getHeaders();
+
+        // Remove the Subject: header
+        $headers->remove('Subject');
+
+        // Remove all X-Foo headers
+        $headers->removeAll('X-Foo');
+
+        // Remove only the second X-Foo header
+        $headers->remove('X-Foo', 1);
+
+Modifying a Header's Content
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To change a Header's content you should know what type of header it is and then
+call it's appropriate setter method. All headers also have a
+``setFieldBodyModel()`` method that accepts a mixed parameter and delegates to
+the correct setter.
+
+To modify an existing header:
+
+* Get the HeaderSet from the entity by via its ``getHeaders()`` method.
+
+* Get the Header by using the HeaderSet's ``get()``.
+
+* Call the Header's appropriate setter method or call the header's
+  ``setFieldBodyModel()`` method.
+
+The header will be updated inside the HeaderSet and the changes will be seen
+when the message is sent.
+
+.. code-block:: php
+
+    $headers = $message->getHeaders();
+
+    // Change the Subject: header
+    $subj = $headers->get('Subject');
+    $subj->setValue('new subject here');
+
+    // Change the To: header
+    $to = $headers->get('To');
+    $to->setNameAddresses(array(
+      'person@example.org' => 'Person',
+      'thing@example.org'
+    ));
+
+    // Using the setFieldBodyModel() just delegates to the correct method
+    // So here to calls setNameAddresses()
+    $to->setFieldBodyModel(array(
+      'person@example.org' => 'Person',
+      'thing@example.org'
+    ));

+Getting Help
+============
+
+There are a number of ways you can get help when using Swift Mailer, depending
+upon the nature of your problem. For bug reports and feature requests create a
+new ticket in GitHub. For general advice ask on the Google Group
+(swiftmailer).
+
+Submitting Bugs & Feature Requests
+----------------------------------
+
+Bugs and feature requests should be posted on GitHub.
+
+If you post a bug or request a feature in the forum, or on the Google Group
+you will most likely be asked to create a ticket in `GitHub`_ since it is
+simply not feasible to manage such requests from a number of a different
+sources.
+
+When you go to GitHub you will be asked to create a username and password
+before you can create a ticket. This is free and takes very little time.
+
+When you create your ticket, do not assign it to any milestones. A developer
+will assess your ticket and re-assign it as needed.
+
+If your ticket is reporting a bug present in the current version, which was
+not present in the previous version please include the tag "regression" in
+your ticket.
+
+GitHub will update you when work is performed on your ticket.
+
+Ask on the Google Group
+-----------------------
+
+You can seek advice at Google Groups, within the "swiftmailer" `group`_.
+
+You can post messages to this group if you want help, or there's something you
+wish to discuss with the developers and with other users.
+
+This is probably the fastest way to get help since it is primarily email-based
+for most users, though bug reports should not be posted here since they may
+not be resolved.

+Including Swift Mailer (Autoloading)
+====================================
+
+If you are using Composer, Swift Mailer will be automatically autoloaded.
+
+If not, you can use the built-in autoloader by requiring the
+``swift_required.php`` file::
+
+    require_once '/path/to/swift-mailer/lib/swift_required.php';
+
+    /* rest of code goes here */
+
+If you want to override the default Swift Mailer configuration, call the
+``init()`` method on the ``Swift`` class and pass it a valid PHP callable (a
+PHP function name, a PHP 5.3 anonymous function, ...)::
+
+    require_once '/path/to/swift-mailer/lib/swift_required.php';
+
+    function swiftmailer_configurator() {
+        // configure Swift Mailer
+
+        Swift_DependencyContainer::getInstance()->...
+        Swift_Preferences::getInstance()->...
+    }
+
+    Swift::init('swiftmailer_configurator');
+
+    /* rest of code goes here */
+
+The advantage of using the ``init()`` method is that your code will be
+executed only if you use Swift Mailer in your script.
+
+.. note::
+
+    While Swift Mailer's autoloader is designed to play nicely with other
+    autoloaders, sometimes you may have a need to avoid using Swift Mailer's
+    autoloader and use your own instead. Include the ``swift_init.php``
+    instead of the ``swift_required.php`` if you need to do this. The very
+    minimum include is the ``swift_init.php`` file since Swift Mailer will not
+    work without the dependency injection this file sets up:
+
+    .. code-block:: php
+
+        require_once '/path/to/swift-mailer/lib/swift_init.php';
+
+        /* rest of code goes here */

+Installing the Library
+======================
+
+Installing with Composer
+------------------------
+
+The recommended way to install Swiftmailer is via Composer:
+
+.. code-block:: bash
+
+    $ php composer.phar require swiftmailer/swiftmailer @stable
+
+Installing from Git
+-------------------
+
+It's possible to download and install Swift Mailer directly from github.com if
+you want to keep up-to-date with ease.
+
+Swift Mailer's source code is kept in a git repository at github.com so you
+can get the source directly from the repository.
+
+.. note::
+
+    You do not need to have git installed to use Swift Mailer from GitHub. If
+    you don't have git installed, go to `GitHub`_ and click the "Download"
+    button.
+
+Cloning the Repository
+~~~~~~~~~~~~~~~~~~~~~~
+
+The repository can be cloned from git://github.com/swiftmailer/swiftmailer.git
+using the ``git clone`` command.
+
+You will need to have ``git`` installed before you can use the
+``git clone`` command.
+
+To clone the repository:
+
+* Open your favorite terminal environment (command line).
+
+* Move to the directory you want to clone to.
+
+* Run the command ``git clone git://github.com/swiftmailer/swiftmailer.git
+  swiftmailer``.
+
+The source code will be downloaded into a directory called "swiftmailer".
+
+The example shows the process on a UNIX-like system such as Linux, BSD or Mac
+OS X.
+
+.. code-block:: bash
+
+    $ cd source_code/
+    $ git clone git://github.com/swiftmailer/swiftmailer.git swiftmailer
+    Initialized empty Git repository in /Users/chris/source_code/swiftmailer/.git/

+    $ cd swiftmailer/
+    $ ls
+    CHANGES LICENSE ...
+    $
+
+Troubleshooting
+---------------
+
+Swift Mailer does not work when used with function overloading as implemented
+by ``mbstring`` (``mbstring.func_overload`` set to ``2``). A workaround is to
+temporarily change the internal encoding to ``ASCII`` when sending an email:
+
+.. code-block:: php
+
+    if (function_exists('mb_internal_encoding') && ((int) ini_get('mbstring.func_overload')) & 2)
+    {
+      $mbEncoding = mb_internal_encoding();
+      mb_internal_encoding('ASCII');
+    }
+
+    // Create your message and send it with Swift Mailer
+
+    if (isset($mbEncoding))
+    {
+      mb_internal_encoding($mbEncoding);
+    }

+Introduction
+============
+
+Swift Mailer is a component-based library for sending e-mails from PHP
+applications.
+
+Organization of this Book
+-------------------------
+
+This book has been written so that those who need information quickly are able
+to find what they need, and those who wish to learn more advanced topics can
+read deeper into each chapter.
+
+The book begins with an overview of Swift Mailer, discussing what's included
+in the package and preparing you for the remainder of the book.
+
+It is possible to read this user guide just like any other book (from
+beginning to end). Each chapter begins with a discussion of the contents it
+contains, followed by a short code sample designed to give you a head start.
+As you get further into a chapter you will learn more about Swift Mailer's
+capabilities, but often you will be able to head directly to the topic you
+wish to learn about.
+
+Throughout this book you will be presented with code samples, which most
+people should find ample to implement Swift Mailer appropriately in their own
+projects. We will also use diagrams where appropriate, and where we believe
+readers may find it helpful we will discuss some related theory, including
+reference to certain documents you are able to find online.
+
+Code Samples
+------------
+
+Code samples presented in this book will be displayed on a different colored
+background in a monospaced font. Samples are not to be taken as copy & paste
+code snippets.
+
+Code examples are used through the book to clarify what is written in text.
+They will sometimes be usable as-is, but they should always be taken as
+outline/pseudo code only.
+
+A code sample will look like this::
+
+    class AClass
+    {
+      ...
+    }
+
+    // A Comment
+    $obj = new AClass($arg1, $arg2, ... );
+
+    /* A note about another way of doing something
+    $obj = AClass::newInstance($arg1, $arg2, ... );
+
+    */
+
+The presence of 3 dots ``...`` in a code sample indicates that we have left
+out a chunk of the code for brevity, they are not actually part of the code.
+
+We will often place multi-line comments ``/* ... */`` in the code so that we
+can show alternative ways of achieving the same result.
+
+You should read the code examples given and try to understand them. They are
+kept concise so that you are not overwhelmed with information.
+
+History of Swift Mailer
+-----------------------
+
+Swift Mailer began back in 2005 as a one-class project for sending mail over
+SMTP. It has since grown into the flexible component-based library that is in
+development today.
+
+Chris Corbyn first posted Swift Mailer on a web forum asking for comments from
+other developers. It was never intended as a fully supported open source
+project, but members of the forum began to adopt it and make use of it.
+
+Very quickly feature requests were coming for the ability to add attachments
+and use SMTP authentication, along with a number of other "obvious" missing
+features. Considering the only alternative was PHPMailer it seemed like a good
+time to bring some fresh tools to the table. Chris began working towards a
+more component based, PHP5-like approach unlike the existing single-class,
+legacy PHP4 approach taken by PHPMailer.
+
+Members of the forum offered a lot of advice and critique on the code as he
+worked through this project and released versions 2 and 3 of the library in
+2005 and 2006, which by then had been broken down into smaller classes
+offering more flexibility and supporting plugins. To this day the Swift Mailer
+team still receive a lot of feature requests from users both on the forum and
+in by email.
+
+Until 2008 Chris was the sole developer of Swift Mailer, but entering 2009 he
+gained the support of two experienced developers well-known to him: Paul
+Annesley and Christopher Thompson. This has been an extremely welcome change.
+
+As of September 2009, Chris handed over the maintenance of Swift Mailer to
+Fabien Potencier.
+
+Now 2009 and in its fourth major version Swift Mailer is more object-oriented
+and flexible than ever, both from a usability standpoint and from a
+development standpoint.
+
+By no means is Swift Mailer ready to call "finished". There are still many
+features that can be added to the library along with the constant refactoring
+that happens behind the scenes.
+
+It's a Library!
+---------------
+
+Swift Mailer is not an application - it's a library.
+
+To most experienced developers this is probably an obvious point to make, but
+it's certainly worth mentioning. Many people often contact us having gotten
+the completely wrong end of the stick in terms of what Swift Mailer is
+actually for.
+
+It's not an application. It does not have a graphical user interface. It
+cannot be opened in your web browser directly.
+
+It's a library (or a framework if you like). It provides a whole lot of
+classes that do some very complicated things, so that you don't have to. You
+"use" Swift Mailer within an application so that your application can have the
+ability to send emails.
+
+The component-based structure of the library means that you are free to
+implement it in a number of different ways and that you can pick and choose
+what you want to use.
+
+An application on the other hand (such as a blog or a forum) is already "put
+together" in a particular way, (usually) provides a graphical user interface
+and most likely doesn't offer a great deal of integration with your own
+application.
+
+Embrace the structure of the library and use the components it offers to your
+advantage. Learning what the components do, rather than blindly copying and
+pasting existing code will put you in a great position to build a powerful
+application!

+Using Swift Mailer for Japanese Emails
+======================================
+
+To send emails in Japanese, you need to tweak the default configuration.
+
+After requiring the Swift Mailer autoloader (by including the
+``swift_required.php`` file), call the ``Swift::init()`` method with the
+following code::
+
+    require_once '/path/to/swift-mailer/lib/swift_required.php';
+
+    Swift::init(function () {
+        Swift_DependencyContainer::getInstance()
+            ->register('mime.qpheaderencoder')
+            ->asAliasOf('mime.base64headerencoder');
+
+        Swift_Preferences::getInstance()->setCharset('iso-2022-jp');
+    });
+
+    /* rest of code goes here */
+
+That's all!

+Creating Messages
+=================
+
+Creating messages in Swift Mailer is done by making use of the various MIME
+entities provided with the library.  Complex messages can be quickly created
+with very little effort.
+
+Quick Reference for Creating a Message
+---------------------------------------
+
+You can think of creating a Message as being similar to the steps you perform
+when you click the Compose button in your mail client.  You give it a subject,
+specify some recipients, add any attachments and write your message.
+
+To create a Message:
+
+* Call the ``newInstance()`` method of ``Swift_Message``.
+
+* Set your sender address (``From:``) with ``setFrom()`` or ``setSender()``.
+
+* Set a subject line with ``setSubject()``.
+
+* Set recipients with ``setTo()``, ``setCc()`` and/or ``setBcc()``.
+
+* Set a body with ``setBody()``.
+
+* Add attachments with ``attach()``.
+
+.. code-block:: php
+
+    require_once 'lib/swift_required.php';
+
+    // Create the message
+    $message = Swift_Message::newInstance()
+
+      // Give the message a subject
+      ->setSubject('Your subject')
+
+      // Set the From address with an associative array
+      ->setFrom(array('john@doe.com' => 'John Doe'))
+
+      // Set the To addresses with an associative array
+      ->setTo(array('receiver@domain.org', 'other@domain.org' => 'A name'))
+
+      // Give it a body
+      ->setBody('Here is the message itself')
+
+      // And optionally an alternative body
+      ->addPart('<q>Here is the message itself</q>', 'text/html')
+
+      // Optionally add any attachments
+      ->attach(Swift_Attachment::fromPath('my-document.pdf'))
+      ;
+
+Message Basics
+--------------
+
+A message is a container for anything you want to send to somebody else. There
+are several basic aspects of a message that you should know.
+
+An e-mail message is made up of several relatively simple entities that are
+combined in different ways to achieve different results. All of these entities
+have the same fundamental outline but serve a different purpose. The Message
+itself can be defined as a MIME entity, an Attachment is a MIME entity, all
+MIME parts are MIME entities -- and so on!
+
+The basic units of each MIME entity -- be it the Message itself, or an
+Attachment -- are its Headers and its body:
+
+.. code-block:: text
+
+    Header-Name: A header value
+    Other-Header: Another value
+
+    The body content itself
+
+The Headers of a MIME entity, and its body must conform to some strict
+standards defined by various RFC documents. Swift Mailer ensures that these
+specifications are followed by using various types of object, including
+Encoders and different Header types to generate the entity.
+
+The Structure of a Message
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Of all of the MIME entities, a message -- ``Swift_Message``
+is the largest and most complex. It has many properties that can be updated
+and it can contain other MIME entities -- attachments for example --
+nested inside it.
+
+A Message has a lot of different Headers which are there to present
+information about the message to the recipients' mail client. Most of these
+headers will be familiar to the majority of users, but we'll list the basic
+ones. Although it's possible to work directly with the Headers of a Message
+(or other MIME entity), the standard Headers have accessor methods provided to
+abstract away the complex details for you. For example, although the Date on a
+message is written with a strict format, you only need to pass a UNIX
+timestamp to ``setDate()``.
+
++-------------------------------+------------------------------------------------------------------------------------------------------------------------------------+---------------------------------------------+
+| Header                        | Description                                                                                                                        | Accessors                                   |
++===============================+====================================================================================================================================+=============================================+
+| ``Message-ID``                | Identifies this message with a unique ID, usually containing the domain name and time generated                                    | ``getId()`` / ``setId()``                   |

+| ``Return-Path``               | Specifies where bounces should go (Swift Mailer reads this for other uses)                                                         | ``getReturnPath()`` / ``setReturnPath()``   |
++-------------------------------+------------------------------------------------------------------------------------------------------------------------------------+---------------------------------------------+
+| ``From``                      | Specifies the address of the person who the message is from. This can be multiple addresses if multiple people wrote the message.  | ``getFrom()`` / ``setFrom()``               |
++-------------------------------+------------------------------------------------------------------------------------------------------------------------------------+---------------------------------------------+
+| ``Sender``                    | Specifies the address of the person who physically sent the message (higher precedence than ``From:``)                             | ``getSender()`` / ``setSender()``           |
++-------------------------------+------------------------------------------------------------------------------------------------------------------------------------+---------------------------------------------+

+| ``Cc``                        | Specifies the addresses of recipients who will be copied in on the message                                                         | ``getCc()`` / ``setCc()``                   |
++-------------------------------+------------------------------------------------------------------------------------------------------------------------------------+---------------------------------------------+
+| ``Bcc``                       | Specifies the addresses of recipients who the message will be blind-copied to. Other recipients will not be aware of these copies. | ``getBcc()`` / ``setBcc()``                 |
++-------------------------------+------------------------------------------------------------------------------------------------------------------------------------+---------------------------------------------+
+| ``Reply-To``                  | Specifies the address where replies are sent to                                                                                    | ``getReplyTo()`` / ``setReplyTo()``         |

++-------------------------------+------------------------------------------------------------------------------------------------------------------------------------+---------------------------------------------+
+
+Working with a Message Object
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Although there are a lot of available methods on a message object, you only
+need to make use of a small subset of them. Usually you'll use
+``setSubject()``, ``setTo()`` and
+``setFrom()`` before setting the body of your message with
+``setBody()``.
+
+Calling methods is simple. You just call them like functions, but using the
+object operator "``->``" to do so. If you've created
+a message object and called it ``$message`` then you'd set a
+subject on it like so:
+
+.. code-block:: php
+
+    require_once 'lib/swift_required.php';
+
+    $message = Swift_Message::newInstance();
+    $message->setSubject('My subject');
+
+All MIME entities (including a message) have a ``toString()``
+method that you can call if you want to take a look at what is going to be
+sent. For example, if you ``echo
+$message->toString();`` you would see something like this:
+
+.. code-block:: bash
+
+    Message-ID: <1230173678.4952f5eeb1432@swift.generated>
+    Date: Thu, 25 Dec 2008 13:54:38 +1100
+    Subject: Example subject
+    From: Chris Corbyn <chris@w3style.co.uk>
+    To: Receiver Name <recipient@example.org>
+    MIME-Version: 1.0
+    Content-Type: text/plain; charset=utf-8
+    Content-Transfer-Encoding: quoted-printable
+
+    Here is the message
+
+We'll take a closer look at the methods you use to create your message in the
+following sections.
+
+Adding Content to Your Message
+------------------------------
+
+Rich content can be added to messages in Swift Mailer with relative ease by
+calling methods such as ``setSubject()``, ``setBody()``, ``addPart()`` and
+``attach()``.
+
+Setting the Subject Line
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The subject line, displayed in the recipients' mail client can be set with the
+``setSubject()`` method, or as a parameter to ``Swift_Message::newInstance()``.
+
+To set the subject of your Message:
+
+* Call the ``setSubject()`` method of the Message, or specify it at the time
+  you create the message.
+
+  .. code-block:: php
+
+    // Pass it as a parameter when you create the message
+    $message = Swift_Message::newInstance('My amazing subject');
+
+    // Or set it after like this
+    $message->setSubject('My amazing subject');
+
+Setting the Body Content
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+The body of the message -- seen when the user opens the message --
+is specified by calling the ``setBody()`` method. If an alternative body is to
+be included ``addPart()`` can be used.
+
+The body of a message is the main part that is read by the user. Often people
+want to send a message in HTML format (``text/html``), other
+times people want to send in plain text (``text/plain``), or
+sometimes people want to send both versions and allow the recipient to choose
+how they view the message.
+
+As a rule of thumb, if you're going to send a HTML email, always include a
+plain-text equivalent of the same content so that users who prefer to read
+plain text can do so.
+
+To set the body of your Message:
+
+* Call the ``setBody()`` method of the Message, or specify it at the time you
+  create the message.
+
+* Add any alternative bodies with ``addPart()``.
+
+If the recipient's mail client offers preferences for displaying text vs. HTML
+then the mail client will present that part to the user where available.  In
+other cases the mail client will display the "best" part it can - usually HTML
+if you've included HTML.
+
+.. code-block:: php
+
+    // Pass it as a parameter when you create the message
+    $message = Swift_Message::newInstance('Subject here', 'My amazing body');
+
+    // Or set it after like this
+    $message->setBody('My <em>amazing</em> body', 'text/html');
+
+    // Add alternative parts with addPart()
+    $message->addPart('My amazing body in plain text', 'text/plain');
+
+Attaching Files
+---------------
+
+Attachments are downloadable parts of a message and can be added by calling
+the ``attach()`` method on the message. You can add attachments that exist on
+disk, or you can create attachments on-the-fly.
+
+Attachments are actually an interesting area of Swift Mailer and something
+that could put a lot of power at your fingertips if you grasp the concept
+behind the way a message is held together.
+
+Although we refer to files sent over e-mails as "attachments" -- because
+they're attached to the message -- lots of other parts of the message are
+actually "attached" even if we don't refer to these parts as attachments.
+
+File attachments are created by the ``Swift_Attachment`` class
+and then attached to the message via the ``attach()`` method on
+it. For all of the "every day" MIME types such as all image formats, word
+documents, PDFs and spreadsheets you don't need to explicitly set the
+content-type of the attachment, though it would do no harm to do so. For less
+common formats you should set the content-type -- which we'll cover in a
+moment.
+
+Attaching Existing Files
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Files that already exist, either on disk or at a URL can be attached to a
+message with just one line of code, using ``Swift_Attachment::fromPath()``.
+
+You can attach files that exist locally, or if your PHP installation has
+``allow_url_fopen`` turned on you can attach files from other
+websites.
+
+To attach an existing file:
+
+* Create an attachment with ``Swift_Attachment::fromPath()``.
+
+* Add the attachment to the message with ``attach()``.
+
+The attachment will be presented to the recipient as a downloadable file with
+the same filename as the one you attached.
+
+.. code-block:: php
+
+    // Create the attachment
+    // * Note that you can technically leave the content-type parameter out
+    $attachment = Swift_Attachment::fromPath('/path/to/image.jpg', 'image/jpeg');
+
+    // Attach it to the message
+    $message->attach($attachment);
+
+    // The two statements above could be written in one line instead
+    $message->attach(Swift_Attachment::fromPath('/path/to/image.jpg'));
+
+    // You can attach files from a URL if allow_url_fopen is on in php.ini
+    $message->attach(Swift_Attachment::fromPath('http://site.tld/logo.png'));
+
+Setting the Filename
+~~~~~~~~~~~~~~~~~~~~
+
+Usually you don't need to explicitly set the filename of an attachment because
+the name of the attached file will be used by default, but if you want to set
+the filename you use the ``setFilename()`` method of the Attachment.
+
+To change the filename of an attachment:
+
+* Call its ``setFilename()`` method.
+
+The attachment will be attached in the normal way, but meta-data sent inside
+the email will rename the file to something else.
+
+.. code-block:: php
+
+    // Create the attachment and call its setFilename() method
+    $attachment = Swift_Attachment::fromPath('/path/to/image.jpg')
+      ->setFilename('cool.jpg');
+
+    // Because there's a fluid interface, you can do this in one statement
+    $message->attach(
+      Swift_Attachment::fromPath('/path/to/image.jpg')->setFilename('cool.jpg')
+    );
+
+Attaching Dynamic Content
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Files that are generated at runtime, such as PDF documents or images created
+via GD can be attached directly to a message without writing them out to disk.
+Use the standard ``Swift_Attachment::newInstance()`` method.
+
+To attach dynamically created content:
+
+* Create your content as you normally would.
+
+* Create an attachment with ``Swift_Attachment::newInstance()``, specifying
+  the source data of your content along with a name and the content-type.
+
+* Add the attachment to the message with ``attach()``.
+
+The attachment will be presented to the recipient as a downloadable file
+with the filename and content-type you specify.
+
+.. note::
+
+    If you would usually write the file to disk anyway you should just attach
+    it with ``Swift_Attachment::fromPath()`` since this will use less memory:
+
+    .. code-block:: php
+
+        // Create your file contents in the normal way, but don't write them to disk
+        $data = create_my_pdf_data();
+
+        // Create the attachment with your data
+        $attachment = Swift_Attachment::newInstance($data, 'my-file.pdf', 'application/pdf');
+
+        // Attach it to the message
+        $message->attach($attachment);
+
+
+        // You can alternatively use method chaining to build the attachment
+        $attachment = Swift_Attachment::newInstance()
+          ->setFilename('my-file.pdf')
+          ->setContentType('application/pdf')
+          ->setBody($data)
+          ;
+
+Changing the Disposition
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Attachments just appear as files that can be saved to the Desktop if desired.
+You can make attachment appear inline where possible by using the
+``setDisposition()`` method of an attachment.
+
+To make an attachment appear inline:
+
+* Call its ``setDisposition()`` method.
+
+The attachment will be displayed within the email viewing window if the mail
+client knows how to display it.
+
+.. note::
+
+    If you try to create an inline attachment for a non-displayable file type
+    such as a ZIP file, the mail client should just present the attachment as
+    normal:
+
+    .. code-block:: php
+
+        // Create the attachment and call its setDisposition() method
+        $attachment = Swift_Attachment::fromPath('/path/to/image.jpg')
+          ->setDisposition('inline');
+
+
+        // Because there's a fluid interface, you can do this in one statement
+        $message->attach(
+          Swift_Attachment::fromPath('/path/to/image.jpg')->setDisposition('inline')
+        );
+
+Embedding Inline Media Files
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Often people want to include an image or other content inline with a HTML
+message. It's easy to do this with HTML linking to remote resources, but this
+approach is usually blocked by mail clients. Swift Mailer allows you to embed
+your media directly into the message.
+
+Mail clients usually block downloads from remote resources because this
+technique was often abused as a mean of tracking who opened an email. If
+you're sending a HTML email and you want to include an image in the message
+another approach you can take is to embed the image directly.
+
+Swift Mailer makes embedding files into messages extremely streamlined. You
+embed a file by calling the ``embed()`` method of the message,
+which returns a value you can use in a ``src`` or
+``href`` attribute in your HTML.
+
+Just like with attachments, it's possible to embed dynamically generated
+content without having an existing file available.
+
+The embedded files are sent in the email as a special type of attachment that
+has a unique ID used to reference them within your HTML attributes. On mail
+clients that do not support embedded files they may appear as attachments.
+
+Although this is commonly done for images, in theory it will work for any
+displayable (or playable) media type. Support for other media types (such as
+video) is dependent on the mail client however.
+
+Embedding Existing Files
+........................
+
+Files that already exist, either on disk or at a URL can be embedded in a
+message with just one line of code, using ``Swift_EmbeddedFile::fromPath()``.
+
+You can embed files that exist locally, or if your PHP installation has
+``allow_url_fopen`` turned on you can embed files from other websites.
+
+To embed an existing file:
+
+* Create a message object with ``Swift_Message::newInstance()``.
+
+* Set the body as HTML, and embed a file at the correct point in the message with ``embed()``.
+
+The file will be displayed with the message inline with the HTML wherever its ID
+is used as a ``src`` attribute.
+
+.. note::
+
+    ``Swift_Image`` and ``Swift_EmbeddedFile`` are just aliases of one
+    another. ``Swift_Image`` exists for semantic purposes.
+
+.. note::
+
+    You can embed files in two stages if you prefer. Just capture the return
+    value of ``embed()`` in a variable and use that as the ``src`` attribute.
+
+    .. code-block:: php
+
+        // Create the message
+        $message = Swift_Message::newInstance('My subject');
+
+        // Set the body
+        $message->setBody(
+        '<html>' .

+        ' <body>' .
+        '  Here is an image <img src="' . // Embed the file

+        '  Rest of message' .
+        ' </body>' .
+        '</html>',
+          'text/html' // Mark the content-type as HTML
+        );
+
+        // You can embed files from a URL if allow_url_fopen is on in php.ini
+        $message->setBody(
+        '<html>' .
+        ' <head></head>' .
+        ' <body>' .
+        '  Here is an image <img src="' .
+             $message->embed(Swift_Image::fromPath('http://site.tld/logo.png')) .
+           '" alt="Image" />' .
+        '  Rest of message' .
+        ' </body>' .
+        '</html>',
+          'text/html'
+        );
+
+
+        // If placing the embed() code inline becomes cumbersome
+        // it's easy to do this in two steps
+        $cid = $message->embed(Swift_Image::fromPath('image.png'));
+
+        $message->setBody(
+        '<html>' .
+        ' <head></head>' .
+        ' <body>' .
+        '  Here is an image <img src="' . $cid . '" alt="Image" />' .
+        '  Rest of message' .
+        ' </body>' .
+        '</html>',
+          'text/html' // Mark the content-type as HTML
+        );
+
+Embedding Dynamic Content
+.........................
+
+Images that are generated at runtime, such as images created via GD can be
+embedded directly to a message without writing them out to disk. Use the
+standard ``Swift_Image::newInstance()`` method.
+
+To embed dynamically created content:
+
+* Create a message object with ``Swift_Message::newInstance()``.
+
+* Set the body as HTML, and embed a file at the correct point in the message
+  with ``embed()``. You will need to specify a filename and a content-type.
+
+The file will be displayed with the message inline with the HTML wherever its ID
+is used as a ``src`` attribute.
+
+.. note::
+
+    ``Swift_Image`` and ``Swift_EmbeddedFile`` are just aliases of one
+    another. ``Swift_Image`` exists for semantic purposes.
+
+.. note::
+
+    You can embed files in two stages if you prefer. Just capture the return
+    value of ``embed()`` in a variable and use that as the ``src`` attribute.
+
+    .. code-block:: php
+
+        // Create your file contents in the normal way, but don't write them to disk
+        $img_data = create_my_image_data();
+
+        // Create the message
+        $message = Swift_Message::newInstance('My subject');
+
+        // Set the body
+        $message->setBody(
+        '<html>' .
+        ' <head></head>' .
+        ' <body>' .
+        '  Here is an image <img src="' . // Embed the file
+             $message->embed(Swift_Image::newInstance($img_data, 'image.jpg', 'image/jpeg')) .
+           '" alt="Image" />' .
+        '  Rest of message' .
+        ' </body>' .
+        '</html>',
+          'text/html' // Mark the content-type as HTML
+        );
+
+
+        // If placing the embed() code inline becomes cumbersome
+        // it's easy to do this in two steps
+        $cid = $message->embed(Swift_Image::newInstance($img_data, 'image.jpg', 'image/jpeg'));
+
+        $message->setBody(
+        '<html>' .
+        ' <head></head>' .
+        ' <body>' .
+        '  Here is an image <img src="' . $cid . '" alt="Image" />' .
+        '  Rest of message' .
+        ' </body>' .
+        '</html>',
+          'text/html' // Mark the content-type as HTML
+        );
+
+Adding Recipients to Your Message
+---------------------------------
+
+Recipients are specified within the message itself via ``setTo()``, ``setCc()``
+and ``setBcc()``. Swift Mailer reads these recipients from the message when it
+gets sent so that it knows where to send the message to.
+
+Message recipients are one of three types:
+
+* ``To:`` recipients -- the primary recipients (required)
+
+* ``Cc:`` recipients -- receive a copy of the message (optional)
+
+* ``Bcc:`` recipients -- hidden from other recipients (optional)
+
+Each type can contain one, or several addresses. It's possible to list only
+the addresses of the recipients, or you can personalize the address by
+providing the real name of the recipient.
+
+Make sure to add only valid email addresses as recipients. If you try to add an
+invalid email address with ``setTo()``, ``setCc()`` or ``setBcc()``, Swift
+Mailer will throw a ``Swift_RfcComplianceException``.
+
+If you add recipients automatically based on a data source that may contain
+invalid email addresses, you can prevent possible exceptions by validating the
+addresses using ``Swift_Validate::email($email)`` and only adding addresses
+that validate. Another way would be to wrap your ``setTo()``, ``setCc()`` and
+``setBcc()`` calls in a try-catch block and handle the
+``Swift_RfcComplianceException`` in the catch block.
+
+.. sidebar:: Syntax for Addresses
+
+    If you only wish to refer to a single email address (for example your
+    ``From:`` address) then you can just use a string.
+
+    .. code-block:: php
+
+          $message->setFrom('some@address.tld');
+
+    If you want to include a name then you must use an associative array.
+
+    .. code-block:: php
+
+         $message->setFrom(array('some@address.tld' => 'The Name'));
+
+    If you want to include multiple addresses then you must use an array.
+
+    .. code-block:: php
+
+         $message->setTo(array('some@address.tld', 'other@address.tld'));
+
+    You can mix personalized (addresses with a name) and non-personalized
+    addresses in the same list by mixing the use of associative and
+    non-associative array syntax.
+
+    .. code-block:: php
+
+         $message->setTo(array(
+           'recipient-with-name@example.org' => 'Recipient Name One',
+           'no-name@example.org', // Note that this is not a key-value pair
+           'named-recipient@example.org' => 'Recipient Name Two'
+         ));
+
+Setting ``To:`` Recipients
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``To:`` recipients are required in a message and are set with the
+``setTo()`` or ``addTo()`` methods of the message.
+
+To set ``To:`` recipients, create the message object using either
+``new Swift_Message( ... )`` or ``Swift_Message::newInstance( ... )``,
+then call the ``setTo()`` method with a complete array of addresses, or use the
+``addTo()`` method to iteratively add recipients.
+
+The ``setTo()`` method accepts input in various formats as described earlier in
+this chapter. The ``addTo()`` method takes either one or two parameters. The
+first being the email address and the second optional parameter being the name
+of the recipient.
+
+``To:`` recipients are visible in the message headers and will be
+seen by the other recipients.
+
+.. note::
+
+    Multiple calls to ``setTo()`` will not add new recipients -- each
+    call overrides the previous calls. If you want to iteratively add
+    recipients, use the ``addTo()`` method.
+
+    .. code-block:: php
+
+        // Using setTo() to set all recipients in one go
+        $message->setTo(array(
+          'person1@example.org',
+          'person2@otherdomain.org' => 'Person 2 Name',
+          'person3@example.org',
+          'person4@example.org',
+          'person5@example.org' => 'Person 5 Name'
+        ));
+
+        // Using addTo() to add recipients iteratively
+        $message->addTo('person1@example.org');
+        $message->addTo('person2@example.org', 'Person 2 Name');
+
+Setting ``Cc:`` Recipients
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``Cc:`` recipients are set with the ``setCc()`` or ``addCc()`` methods of the
+message.
+
+To set ``Cc:`` recipients, create the message object using either
+``new Swift_Message( ... )`` or ``Swift_Message::newInstance( ... )``, then call
+the ``setCc()`` method with a complete array of addresses, or use the
+``addCc()`` method to iteratively add recipients.
+
+The ``setCc()`` method accepts input in various formats as described earlier in
+this chapter. The ``addCc()`` method takes either one or two parameters. The
+first being the email address and the second optional parameter being the name
+of the recipient.
+
+``Cc:`` recipients are visible in the message headers and will be
+seen by the other recipients.
+
+.. note::
+
+    Multiple calls to ``setCc()`` will not add new recipients -- each
+    call overrides the previous calls. If you want to iteratively add Cc:
+    recipients, use the ``addCc()`` method.
+
+    .. code-block:: php
+
+        // Using setCc() to set all recipients in one go
+        $message->setCc(array(
+          'person1@example.org',
+          'person2@otherdomain.org' => 'Person 2 Name',
+          'person3@example.org',
+          'person4@example.org',
+          'person5@example.org' => 'Person 5 Name'
+        ));
+
+        // Using addCc() to add recipients iteratively
+        $message->addCc('person1@example.org');
+        $message->addCc('person2@example.org', 'Person 2 Name');
+
+Setting ``Bcc:`` Recipients
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``Bcc:`` recipients receive a copy of the message without anybody else knowing
+it, and are set with the ``setBcc()`` or ``addBcc()`` methods of the message.
+
+To set ``Bcc:`` recipients, create the message object using either ``new
+Swift_Message( ... )`` or ``Swift_Message::newInstance( ... )``, then call the
+``setBcc()`` method with a complete array of addresses, or use
+the ``addBcc()`` method to iteratively add recipients.
+
+The ``setBcc()`` method accepts input in various formats as described earlier in
+this chapter. The ``addBcc()`` method takes either one or two parameters. The
+first being the email address and the second optional parameter being the name
+of the recipient.
+
+Only the individual ``Bcc:`` recipient will see their address in the message
+headers. Other recipients (including other ``Bcc:`` recipients) will not see the
+address.
+
+.. note::
+
+    Multiple calls to ``setBcc()`` will not add new recipients -- each
+    call overrides the previous calls. If you want to iteratively add Bcc:
+    recipients, use the ``addBcc()`` method.
+
+    .. code-block:: php
+
+        // Using setBcc() to set all recipients in one go
+        $message->setBcc(array(
+          'person1@example.org',
+          'person2@otherdomain.org' => 'Person 2 Name',
+          'person3@example.org',
+          'person4@example.org',
+          'person5@example.org' => 'Person 5 Name'
+        ));
+
+        // Using addBcc() to add recipients iteratively
+        $message->addBcc('person1@example.org');
+        $message->addBcc('person2@example.org', 'Person 2 Name');
+
+Specifying Sender Details
+-------------------------
+
+An email must include information about who sent it. Usually this is managed
+by the ``From:`` address, however there are other options.
+
+The sender information is contained in three possible places:
+
+* ``From:`` -- the address(es) of who wrote the message (required)
+
+* ``Sender:`` -- the address of the single person who sent the message
+  (optional)
+
+* ``Return-Path:`` -- the address where bounces should go to (optional)
+
+You must always include a ``From:`` address by using ``setFrom()`` on the
+message. Swift Mailer will use this as the default ``Return-Path:`` unless
+otherwise specified.
+
+The ``Sender:`` address exists because the person who actually sent the email
+may not be the person who wrote the email. It has a higher precedence than the
+``From:`` address and will be used as the ``Return-Path:`` unless otherwise
+specified.
+
+Setting the ``From:`` Address
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A ``From:`` address is required and is set with the ``setFrom()`` method of the
+message. ``From:`` addresses specify who actually wrote the email, and usually who sent it.
+
+What most people probably don't realise is that you can have more than one
+``From:`` address if more than one person wrote the email -- for example if an
+email was put together by a committee.
+
+To set the ``From:`` address(es):
+
+* Call the ``setFrom()`` method on the Message.
+
+The ``From:`` address(es) are visible in the message headers and
+will be seen by the recipients.
+
+.. note::
+
+    If you set multiple ``From:`` addresses then you absolutely must set a
+    ``Sender:`` address to indicate who physically sent the message.
+
+    .. code-block:: php
+
+        // Set a single From: address
+        $message->setFrom('your@address.tld');
+
+        // Set a From: address including a name
+        $message->setFrom(array('your@address.tld' => 'Your Name'));
+
+        // Set multiple From: addresses if multiple people wrote the email
+        $message->setFrom(array(
+          'person1@example.org' => 'Sender One',
+          'person2@example.org' => 'Sender Two'
+        ));
+
+Setting the ``Sender:`` Address
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A ``Sender:`` address specifies who sent the message and is set with the
+``setSender()`` method of the message.
+
+To set the ``Sender:`` address:
+
+* Call the ``setSender()`` method on the Message.
+
+The ``Sender:`` address is visible in the message headers and will be seen by
+the recipients.
+
+This address will be used as the ``Return-Path:`` unless otherwise specified.
+
+.. note::
+
+    If you set multiple ``From:`` addresses then you absolutely must set a
+    ``Sender:`` address to indicate who physically sent the message.
+
+You must not set more than one sender address on a message because it's not
+possible for more than one person to send a single message.
+
+.. code-block:: php
+
+    $message->setSender('your@address.tld');
+
+Setting the ``Return-Path:`` (Bounce) Address
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``Return-Path:`` address specifies where bounce notifications should
+be sent and is set with the ``setReturnPath()`` method of the message.
+
+You can only have one ``Return-Path:`` and it must not include
+a personal name.
+
+To set the ``Return-Path:`` address:
+
+* Call the ``setReturnPath()`` method on the Message.
+
+Bounce notifications will be sent to this address.
+
+.. code-block:: php
+
+    $message->setReturnPath('bounces@address.tld');
+
+
+Signed/Encrypted Message
+------------------------
+
+To increase the integrity/security of a message it is possible to sign and/or
+encrypt an message using one or multiple signers.
+
+S/MIME
+~~~~~~
+
+S/MIME can sign and/or encrypt a message using the OpenSSL extension.
+
+When signing a message, the signer creates a signature of the entire content of the message (including attachments).
+
+The certificate and private key must be PEM encoded, and can be either created using for example OpenSSL or
+obtained at an official Certificate Authority (CA).
+
+**The recipient must have the CA certificate in the list of trusted issuers in order to verify the signature.**
+
+**Make sure the certificate supports emailProtection.**
+
+When using OpenSSL this can done by the including the *-addtrust emailProtection* parameter when creating the certificate.
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance();
+
+    $smimeSigner = Swift_Signers_SMimeSigner::newInstance();
+    $smimeSigner->setSignCertificate('/path/to/certificate.pem', '/path/to/private-key.pem');
+    $message->attachSigner($smimeSigner);
+
+When the private key is secured using a passphrase use the following instead.
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance();
+
+    $smimeSigner = Swift_Signers_SMimeSigner::newInstance();
+    $smimeSigner->setSignCertificate('/path/to/certificate.pem', array('/path/to/private-key.pem', 'passphrase'));
+    $message->attachSigner($smimeSigner);
+
+By default the signature is added as attachment,
+making the message still readable for mailing agents not supporting signed messages.
+
+Storing the message as binary is also possible but not recommended.
+
+.. code-block:: php
+
+    $smimeSigner->setSignCertificate('/path/to/certificate.pem', '/path/to/private-key.pem', PKCS7_BINARY);
+
+When encrypting the message (also known as enveloping), the entire message (including attachments)
+is encrypted using a certificate, and the recipient can then decrypt the message using corresponding private key.
+
+Encrypting ensures nobody can read the contents of the message without the private key.
+
+Normally the recipient provides a certificate for encrypting and keeping the decryption key private.
+
+Using both signing and encrypting is also possible.
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance();
+
+    $smimeSigner = Swift_Signers_SMimeSigner::newInstance();
+    $smimeSigner->setSignCertificate('/path/to/sign-certificate.pem', '/path/to/private-key.pem');
+    $smimeSigner->setEncryptCertificate('/path/to/encrypt-certificate.pem');
+    $message->attachSigner($smimeSigner);
+
+The used encryption cipher can be set as the second parameter of setEncryptCertificate()
+
+See http://php.net/manual/openssl.ciphers for a list of supported ciphers.
+
+By default the message is first signed and then encrypted, this can be changed by adding.
+
+.. code-block:: php
+
+    $smimeSigner->setSignThenEncrypt(false);
+
+**Changing this is not recommended as most mail agents don't support this none-standard way.**
+
+Only when having trouble with sign then encrypt method, this should be changed.
+
+Requesting a Read Receipt
+-------------------------
+
+It is possible to request a read-receipt to be sent to an address when the
+email is opened. To request a read receipt set the address with
+``setReadReceiptTo()``.
+
+To request a read receipt:
+
+* Set the address you want the receipt to be sent to with the
+  ``setReadReceiptTo()`` method on the Message.
+
+When the email is opened, if the mail client supports it a notification will be sent to this address.
+
+.. note::
+
+    Read receipts won't work for the majority of recipients since many mail
+    clients auto-disable them. Those clients that will send a read receipt
+    will make the user aware that one has been requested.
+
+    .. code-block:: php
+
+        $message->setReadReceiptTo('your@address.tld');
+
+Setting the Character Set
+-------------------------
+
+The character set of the message (and it's MIME parts) is set with the
+``setCharset()`` method. You can also change the global default of UTF-8 by
+working with the ``Swift_Preferences`` class.
+
+Swift Mailer will default to the UTF-8 character set unless otherwise
+overridden. UTF-8 will work in most instances since it includes all of the
+standard US keyboard characters in addition to most international characters.
+
+It is absolutely vital however that you know what character set your message
+(or it's MIME parts) are written in otherwise your message may be received
+completely garbled.
+
+There are two places in Swift Mailer where you can change the character set:
+
+* In the ``Swift_Preferences`` class
+
+* On each individual message and/or MIME part
+
+To set the character set of your Message:
+
+* Change the global UTF-8 setting by calling
+  ``Swift_Preferences::setCharset()``; or
+
+* Call the ``setCharset()`` method on the message or the MIME part.
+
+   .. code-block:: php
+
+    // Approach 1: Change the global setting (suggested)
+    Swift_Preferences::getInstance()->setCharset('iso-8859-2');
+
+    // Approach 2: Call the setCharset() method of the message
+    $message = Swift_Message::newInstance()
+      ->setCharset('iso-8859-2');
+
+    // Approach 3: Specify the charset when setting the body
+    $message->setBody('My body', 'text/html', 'iso-8859-2');
+
+    // Approach 4: Specify the charset for each part added
+    $message->addPart('My part', 'text/plain', 'iso-8859-2');
+
+Setting the Line Length
+-----------------------
+
+The length of lines in a message can be changed by using the ``setMaxLineLength()`` method on the message. It should be kept to less than
+1000 characters.
+
+Swift Mailer defaults to using 78 characters per line in a message. This is
+done for historical reasons and so that the message can be easily viewed in
+plain-text terminals.
+
+To change the maximum length of lines in your Message:
+
+* Call the ``setMaxLineLength()`` method on the Message.
+
+Lines that are longer than the line length specified will be wrapped between
+words.
+
+.. note::
+
+    You should never set a maximum length longer than 1000 characters
+    according to RFC 2822. Doing so could have unspecified side-effects such
+    as truncating parts of your message when it is transported between SMTP
+    servers.
+
+    .. code-block:: php
+
+        $message->setMaxLineLength(1000);
+
+Setting the Message Priority
+----------------------------
+
+You can change the priority of the message with ``setPriority()``. Setting the
+priority will not change the way your email is sent -- it is purely an
+indicative setting for the recipient.
+
+The priority of a message is an indication to the recipient what significance
+it has. Swift Mailer allows you to set the priority by calling the
+``setPriority`` method. This method takes an integer value between 1 and 5:
+
+* `Swift_Mime_SimpleMessage::PRIORITY_HIGHEST`: 1
+* `Swift_Mime_SimpleMessage::PRIORITY_HIGH`: 2
+* `Swift_Mime_SimpleMessage::PRIORITY_NORMAL`: 3
+* `Swift_Mime_SimpleMessage::PRIORITY_LOW`: 4
+* `Swift_Mime_SimpleMessage::PRIORITY_LOWEST`: 5
+
+To set the message priority:
+
+* Set the priority as an integer between 1 and 5 with the ``setPriority()``
+  method on the Message.
+
+.. code-block:: php
+
+    // Indicate "High" priority
+    $message->setPriority(2);
+
+    // Or use the constant to be more explicit
+    $message->setPriority(Swift_Mime_SimpleMessage::PRIORITY_HIGH);

+Library Overview
+================
+
+Most features (and more) of your every day mail client software are provided
+by Swift Mailer, using object-oriented PHP code as the interface.
+
+In this chapter we will take a short tour of the various components, which put
+together form the Swift Mailer library as a whole. You will learn key
+terminology used throughout the rest of this book and you will gain a little
+understanding of the classes you will work with as you integrate Swift Mailer
+into your application.
+
+This chapter is intended to prepare you for the information contained in the
+subsequent chapters of this book. You may choose to skip this chapter if you
+are fairly technically minded, though it is likely to save you some time in
+the long run if you at least read between the lines here.
+
+System Requirements
+-------------------
+
+The basic requirements to operate Swift Mailer are extremely minimal and
+easily achieved. Historically, Swift Mailer has supported both PHP 4 and PHP 5
+by following a parallel development workflow. Now in it's fourth major
+version, and Swift Mailer operates on servers running PHP 5.3.3 or higher.
+
+The library aims to work with as many PHP 5 projects as possible:
+
+* PHP 5.3.3 or higher, with the SPL extension (standard)
+
+* Limited network access to connect to remote SMTP servers
+
+* 8 MB or more memory limit (Swift Mailer uses around 2 MB)
+

+Swift Mailer is made up of many classes. Each of these classes can be grouped
+into a general "component" group which describes the task it is designed to
+perform.
+
+We'll take a brief look at the components which form Swift Mailer in this
+section of the book.
+
+The Mailer
+~~~~~~~~~~
+
+The mailer class, ``Swift_Mailer`` is the central class in the library where
+all of the other components meet one another. ``Swift_Mailer`` acts as a sort
+of message dispatcher, communicating with the underlying Transport to deliver
+your Message to all intended recipients.
+
+If you were to dig around in the source code for Swift Mailer you'd notice
+that ``Swift_Mailer`` itself is pretty bare. It delegates to other objects for
+most tasks and in theory, if you knew the internals of Swift Mailer well you
+could by-pass this class entirely. We wouldn't advise doing such a thing
+however -- there are reasons this class exists:
+
+* for consistency, regardless of the Transport used
+
+* to provide abstraction from the internals in the event internal API changes
+  are made
+
+* to provide convenience wrappers around aspects of the internal API
+
+An instance of ``Swift_Mailer`` is created by the developer before sending any
+Messages.
+
+Transports
+~~~~~~~~~~
+
+Transports are the classes in Swift Mailer that are responsible for
+communicating with a service in order to deliver a Message. There are several
+types of Transport in Swift Mailer, all of which implement the Swift_Transport
+interface and offer underlying start(), stop() and send() methods.
+
+Typically you will not need to know how a Transport works under-the-surface,
+you will only need to know how to create an instance of one, and which one to
+use for your environment.

++---------------------------------+---------------------------------------------------------------------------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------+
+
+MIME Entities
+~~~~~~~~~~~~~
+
+Everything that forms part of a Message is called a MIME Entity. All MIME
+entities in Swift Mailer share a common set of features. There are various
+types of MIME entity that serve different purposes such as Attachments and
+MIME parts.
+
+An e-mail message is made up of several relatively simple entities that are
+combined in different ways to achieve different results. All of these entities
+have the same fundamental outline but serve a different purpose. The Message
+itself can be defined as a MIME entity, an Attachment is a MIME entity, all
+MIME parts are MIME entities -- and so on!
+
+The basic units of each MIME entity -- be it the Message itself, or an
+Attachment -- are its Headers and its body:
+
+.. code-block:: text
+
+    Other-Header: Another value
+
+    The body content itself
+
+The Headers of a MIME entity, and its body must conform to some strict
+standards defined by various RFC documents. Swift Mailer ensures that these
+specifications are followed by using various types of object, including
+Encoders and different Header types to generate the entity.
+
+Each MIME component implements the base ``Swift_Mime_MimeEntity`` interface,
+which offers methods for retrieving Headers, adding new Headers, changing the
+Encoder, updating the body and so on!
+
+All MIME entities have one Header in common -- the Content-Type Header,
+updated with the entity's ``setContentType()`` method.
+
+Encoders
+~~~~~~~~
+
+Encoders are used to transform the content of Messages generated in Swift
+Mailer into a format that is safe to send across the internet and that
+conforms to RFC specifications.
+
+Generally speaking you will not need to interact with the Encoders in Swift
+Mailer -- the correct settings will be handled by the library itself.
+However they are probably worth a brief mention in the event that you do want
+to play with them.
+
+Both the Headers and the body of all MIME entities (including the Message
+itself) use Encoders to ensure the data they contain can be sent over the
+internet without becoming corrupted or misinterpreted.
+
+There are two types of Encoder: Base64 and Quoted-Printable.
+
+Plugins
+~~~~~~~
+
+Plugins exist to extend, or modify the behaviour of Swift Mailer. They respond
+to Events that are fired within the Transports during sending.
+
+There are a number of Plugins provided as part of the base Swift Mailer
+package and they all follow a common interface to respond to Events fired
+within the library. Interfaces are provided to "listen" to each type of Event
+fired and to act as desired when a listened-to Event occurs.
+
+Although several plugins are provided with Swift Mailer out-of-the-box, the
+Events system has been specifically designed to make it easy for experienced
+object-oriented developers to write their own plugins in order to achieve
+goals that may not be possible with the base library.

+Plugins
+=======
+
+Plugins are provided with Swift Mailer and can be used to extend the behavior
+of the library in situations where using simple class inheritance would be more complex.
+
+AntiFlood Plugin
+----------------
+
+Many SMTP servers have limits on the number of messages that may be sent
+during any single SMTP connection. The AntiFlood plugin provides a way to stay
+within this limit while still managing a large number of emails.
+
+A typical limit for a single connection is 100 emails. If the server you
+connect to imposes such a limit, it expects you to disconnect after that
+number of emails has been sent. You could manage this manually within a loop,
+but the AntiFlood plugin provides the necessary wrapper code so that you don't
+need to worry about this logic.
+
+Regardless of limits imposed by the server, it's usually a good idea to be
+conservative with the resources of the SMTP server. Sending will become
+sluggish if the server is being over-used so using the AntiFlood plugin will
+not be a bad idea even if no limits exist.
+
+The AntiFlood plugin's logic is basically to disconnect and the immediately
+re-connect with the SMTP server every X number of emails sent, where X is a
+number you specify to the plugin.
+
+You can also specify a time period in seconds that Swift Mailer should pause
+for between the disconnect/re-connect process. It's a good idea to pause for a
+short time (say 30 seconds every 100 emails) simply to give the SMTP server a
+chance to process its queue and recover some resources.
+
+Using the AntiFlood Plugin
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The AntiFlood Plugin -- like all plugins -- is added with the Mailer class's
+``registerPlugin()`` method. It takes two constructor parameters: the number of
+emails to pause after, and optionally the number of seconds to pause for.
+
+To use the AntiFlood plugin:
+
+* Create an instance of the Mailer using any Transport you choose.
+
+* Create an instance of the ``Swift_Plugins_AntiFloodPlugin`` class, passing
+  in one or two constructor parameters.
+
+* Register the plugin using the Mailer's ``registerPlugin()`` method.
+
+* Continue using Swift Mailer to send messages as normal.
+
+When Swift Mailer sends messages it will count the number of messages that
+have been sent since the last re-connect. Once the number hits your specified
+threshold it will disconnect and re-connect, optionally pausing for a
+specified amount of time.
+
+.. code-block:: php
+
+    require_once 'lib/swift_required.php';
+
+    // Create the Mailer using any Transport
+    $mailer = Swift_Mailer::newInstance(
+      Swift_SmtpTransport::newInstance('smtp.example.org', 25)
+    );
+
+    // Use AntiFlood to re-connect after 100 emails
+    $mailer->registerPlugin(new Swift_Plugins_AntiFloodPlugin(100));
+
+    // And specify a time in seconds to pause for (30 secs)
+    $mailer->registerPlugin(new Swift_Plugins_AntiFloodPlugin(100, 30));
+
+    // Continue sending as normal
+    for ($lotsOfRecipients as $recipient) {
+      ...
+
+      $mailer->send( ... );
+    }
+
+Throttler Plugin
+----------------
+
+If your SMTP server has restrictions in place to limit the rate at which you
+send emails, then your code will need to be aware of this rate-limiting. The
+Throttler plugin makes Swift Mailer run at a rate-limited speed.
+
+Many shared hosts don't open their SMTP servers as a free-for-all. Usually
+they have policies in place (probably to discourage spammers) that only allow
+you to send a fixed number of emails per-hour/day.
+
+The Throttler plugin supports two modes of rate-limiting and with each, you
+will need to do that math to figure out the values you want. The plugin can
+limit based on the number of emails per minute, or the number of
+bytes-transferred per-minute.
+
+Using the Throttler Plugin
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Throttler Plugin -- like all plugins -- is added with the Mailer class'
+``registerPlugin()`` method. It has two required constructor parameters that
+tell it how to do its rate-limiting.
+
+To use the Throttler plugin:
+
+* Create an instance of the Mailer using any Transport you choose.
+
+* Create an instance of the ``Swift_Plugins_ThrottlerPlugin`` class, passing
+  the number of emails, or bytes you wish to limit by, along with the mode
+  you're using.
+
+* Register the plugin using the Mailer's ``registerPlugin()`` method.
+
+* Continue using Swift Mailer to send messages as normal.
+
+When Swift Mailer sends messages it will keep track of the rate at which sending
+messages is occurring. If it realises that sending is happening too fast, it
+will cause your program to ``sleep()`` for enough time to average out the rate.
+
+.. code-block:: php
+
+    require_once 'lib/swift_required.php';
+
+    // Create the Mailer using any Transport
+    $mailer = Swift_Mailer::newInstance(
+      Swift_SmtpTransport::newInstance('smtp.example.org', 25)
+    );
+
+    // Rate limit to 100 emails per-minute
+    $mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin(
+      100, Swift_Plugins_ThrottlerPlugin::MESSAGES_PER_MINUTE
+    ));
+
+    // Rate limit to 10MB per-minute
+    $mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin(
+      1024 * 1024 * 10, Swift_Plugins_ThrottlerPlugin::BYTES_PER_MINUTE
+    ));
+
+    // Continue sending as normal
+    for ($lotsOfRecipients as $recipient) {
+      ...
+
+      $mailer->send( ... );
+    }
+
+Logger Plugin
+-------------
+
+The Logger plugins helps with debugging during the process of sending. It can
+help to identify why an SMTP server is rejecting addresses, or any other
+hard-to-find problems that may arise.
+
+The Logger plugin comes in two parts. There's the plugin itself, along with
+one of a number of possible Loggers that you may choose to use. For example,
+the logger may output messages directly in realtime, or it may capture
+messages in an array.
+
+One other notable feature is the way in which the Logger plugin changes
+Exception messages. If Exceptions are being thrown but the error message does
+not provide conclusive information as to the source of the problem (such as an
+ambiguous SMTP error) the Logger plugin includes the entire SMTP transcript in
+the error message so that debugging becomes a simpler task.
+
+There are a few available Loggers included with Swift Mailer, but writing your
+own implementation is incredibly simple and is achieved by creating a short
+class that implements the ``Swift_Plugins_Logger`` interface.
+
+* ``Swift_Plugins_Loggers_ArrayLogger``: Keeps a collection of log messages
+  inside an array. The array content can be cleared or dumped out to the
+  screen.
+
+* ``Swift_Plugins_Loggers_EchoLogger``: Prints output to the screen in
+  realtime. Handy for very rudimentary debug output.
+
+Using the Logger Plugin
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The Logger Plugin -- like all plugins -- is added with the Mailer class'
+``registerPlugin()`` method. It accepts an instance of ``Swift_Plugins_Logger``
+in its constructor.
+
+To use the Logger plugin:
+
+* Create an instance of the Mailer using any Transport you choose.
+
+* Create an instance of the a Logger implementation of
+  ``Swift_Plugins_Logger``.
+
+* Create an instance of the ``Swift_Plugins_LoggerPlugin`` class, passing the
+  created Logger instance to its constructor.
+
+* Register the plugin using the Mailer's ``registerPlugin()`` method.
+
+* Continue using Swift Mailer to send messages as normal.
+
+* Dump the contents of the log with the logger's ``dump()`` method.
+
+When Swift Mailer sends messages it will keep a log of all the interactions
+with the underlying Transport being used. Depending upon the Logger that has
+been used the behaviour will differ, but all implementations offer a way to
+get the contents of the log.
+
+.. code-block:: php
+
+    require_once 'lib/swift_required.php';
+
+    // Create the Mailer using any Transport
+    $mailer = Swift_Mailer::newInstance(
+     Swift_SmtpTransport::newInstance('smtp.example.org', 25)
+    );
+
+    // To use the ArrayLogger
+    $logger = new Swift_Plugins_Loggers_ArrayLogger();
+    $mailer->registerPlugin(new Swift_Plugins_LoggerPlugin($logger));
+
+    // Or to use the Echo Logger
+    $logger = new Swift_Plugins_Loggers_EchoLogger();
+    $mailer->registerPlugin(new Swift_Plugins_LoggerPlugin($logger));
+
+    // Continue sending as normal
+    for ($lotsOfRecipients as $recipient) {
+     ...
+
+     $mailer->send( ... );
+    }
+
+    // Dump the log contents
+    // NOTE: The EchoLogger dumps in realtime so dump() does nothing for it
+    echo $logger->dump();
+
+Decorator Plugin
+----------------
+
+Often there's a need to send the same message to multiple recipients, but with
+tiny variations such as the recipient's name being used inside the message
+body. The Decorator plugin aims to provide a solution for allowing these small
+differences.
+
+The decorator plugin works by intercepting the sending process of Swift
+Mailer, reading the email address in the To: field and then looking up a set
+of replacements for a template.
+
+While the use of this plugin is simple, it is probably the most commonly
+misunderstood plugin due to the way in which it works. The typical mistake
+users make is to try registering the plugin multiple times (once for each
+recipient) -- inside a loop for example. This is incorrect.
+
+The Decorator plugin should be registered just once, but containing the list
+of all recipients prior to sending. It will use this list of recipients to
+find the required replacements during sending.
+
+Using the Decorator Plugin
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To use the Decorator plugin, simply create an associative array of replacements
+based on email addresses and then use the mailer's ``registerPlugin()`` method
+to add the plugin.
+
+First create an associative array of replacements based on the email addresses
+you'll be sending the message to.
+
+.. note::
+
+    The replacements array becomes a 2-dimensional array whose keys are the
+    email addresses and whose values are an associative array of replacements
+    for that email address. The curly braces used in this example can be any
+    type of syntax you choose, provided they match the placeholders in your
+    email template.
+
+    .. code-block:: php
+
+        $replacements = array();
+        foreach ($users as $user) {
+          $replacements[$user['email']] = array(
+            '{username}'=>$user['username'],
+            '{password}'=>$user['password']
+          );
+        }
+
+Now create an instance of the Decorator plugin using this array of replacements
+and then register it with the Mailer. Do this only once!
+
+.. code-block:: php
+
+    $decorator = new Swift_Plugins_DecoratorPlugin($replacements);
+
+    $mailer->registerPlugin($decorator);
+
+When you create your message, replace elements in the body (and/or the subject
+line) with your placeholders.
+
+.. code-block:: php
+
+    $message = Swift_Message::newInstance()
+      ->setSubject('Important notice for {username}')
+      ->setBody(
+        "Hello {username}, we have reset your password to {password}\n" .
+        "Please log in and change it at your earliest convenience."
+      )
+      ;
+
+    foreach ($users as $user) {
+      $message->addTo($user['email']);
+    }
+
+When you send this message to each of your recipients listed in your
+``$replacements`` array they will receive a message customized for just
+themselves. For example, the message used above when received may appear like
+this to one user:
+
+.. code-block:: text
+
+    Subject: Important notice for smilingsunshine2009
+
+    Hello smilingsunshine2009, we have reset your password to rainyDays
+    Please log in and change it at your earliest convenience.
+
+While another use may receive the message as:
+
+.. code-block:: text
+
+    Subject: Important notice for billy-bo-bob
+
+    Hello billy-bo-bob, we have reset your password to dancingOctopus
+    Please log in and change it at your earliest convenience.
+
+While the decorator plugin provides a means to solve this problem, there are
+various ways you could tackle this problem without the need for a plugin.
+We're trying to come up with a better way ourselves and while we have several
+(obvious) ideas we don't quite have the perfect solution to go ahead and
+implement it. Watch this space.
+
+Providing Your Own Replacements Lookup for the Decorator
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Filling an array with replacements may not be the best solution for providing
+replacement information to the decorator. If you have a more elegant algorithm
+that performs replacement lookups on-the-fly you may provide your own
+implementation.
+
+Providing your own replacements lookup implementation for the Decorator is
+simply a matter of passing an instance of ``Swift_Plugins_Decorator_Replacements`` to the decorator plugin's constructor,
+rather than passing in an array.
+
+The Replacements interface is very simple to implement since it has just one
+method: ``getReplacementsFor($address)``.
+
+Imagine you want to look up replacements from a database on-the-fly, you might
+provide an implementation that does this. You need to create a small class.
+
+.. code-block:: php
+
+    class DbReplacements implements Swift_Plugins_Decorator_Replacements {
+      public function getReplacementsFor($address) {
+        global $db; // Your PDO instance with a connection to your database
+        $query = $db->prepare(
+          "SELECT * FROM `users` WHERE `email` = ?"
+        );
+
+        $query->execute([$address]);
+
+        if ($row = $query->fetch(PDO::FETCH_ASSOC)) {
+          return array(
+            '{username}'=>$row['username'],
+            '{password}'=>$row['password']
+          );
+        }
+      }
+    }
+
+Now all you need to do is pass an instance of your class into the Decorator
+plugin's constructor instead of passing an array.
+
+.. code-block:: php
+
+    $decorator = new Swift_Plugins_DecoratorPlugin(new DbReplacements());
+
+    $mailer->registerPlugin($decorator);
+
+For each message sent, the plugin will call your class' ``getReplacementsFor()``
+method to find the array of replacements it needs.
+
+.. note::
+
+    If your lookup algorithm is case sensitive, you should transform the
+    ``$address`` argument as appropriate -- for example by passing it
+    through ``strtolower()``.

+Sending Messages
+================
+
+Quick Reference for Sending a Message
+-------------------------------------
+
+Sending a message is very straightforward. You create a Transport, use it to
+create the Mailer, then you use the Mailer to send the message.
+
+To send a Message:
+
+* Create a Transport from one of the provided Transports --
+  ``Swift_SmtpTransport``, ``Swift_SendmailTransport``
+  or one of the aggregate Transports.
+
+* Create an instance of the ``Swift_Mailer`` class, using the Transport as
+  it's constructor parameter.
+
+* Create a Message.
+
+* Send the message via the ``send()`` method on the Mailer object.
+
+.. caution::
+
+    The ``Swift_SmtpTransport`` and ``Swift_SendmailTransport`` transports use
+    ``proc_*`` PHP functions, which might not be available on your PHP
+    installation. You can easily check if that's the case by running the
+    following PHP script: ``<?php echo function_exists('proc_open') ? "Yep,
+    that will work" : "Sorry, that won't work";``
+
+When using ``send()`` the message will be sent just like it would be sent if you
+used your mail client. An integer is returned which includes the number of
+successful recipients. If none of the recipients could be sent to then zero will
+be returned, which equates to a boolean ``false``. If you set two ``To:``
+recipients and three ``Bcc:`` recipients in the message and all of the
+recipients are delivered to successfully then the value 5 will be returned.
+
+.. code-block:: php
+
+    require_once 'lib/swift_required.php';
+
+    // Create the Transport
+    $transport = Swift_SmtpTransport::newInstance('smtp.example.org', 25)
+      ->setUsername('your username')
+      ->setPassword('your password')
+      ;
+
+    /*
+    You could alternatively use a different transport such as Sendmail:
+
+    // Sendmail
+    $transport = Swift_SendmailTransport::newInstance('/usr/sbin/sendmail -bs');
+    */
+
+    // Create the Mailer using your created Transport
+    $mailer = Swift_Mailer::newInstance($transport);
+
+    // Create a message
+    $message = Swift_Message::newInstance('Wonderful Subject')
+      ->setFrom(array('john@doe.com' => 'John Doe'))
+      ->setTo(array('receiver@domain.org', 'other@domain.org' => 'A name'))
+      ->setBody('Here is the message itself')
+      ;
+
+    // Send the message
+    $result = $mailer->send($message);
+
+Transport Types
+~~~~~~~~~~~~~~~
+
+A Transport is the component which actually does the sending. You need to
+provide a Transport object to the Mailer class and there are several possible
+options.
+
+Typically you will not need to know how a Transport works under-the-surface,
+you will only need to know how to create an instance of one, and which one to
+use for your environment.
+
+The SMTP Transport
+..................
+
+The SMTP Transport sends messages over the (standardized) Simple Message
+Transfer Protocol.  It can deal with encryption and authentication.
+
+The SMTP Transport, ``Swift_SmtpTransport`` is without doubt the most commonly
+used Transport because it will work on 99% of web servers (I just made that
+number up, but you get the idea). All the server needs is the ability to
+connect to a remote (or even local) SMTP server on the correct port number
+(usually 25).
+
+SMTP servers often require users to authenticate with a username and password
+before any mail can be sent to other domains. This is easily achieved using
+Swift Mailer with the SMTP Transport.
+
+SMTP is a protocol -- in other words it's a "way" of communicating a job
+to be done (i.e. sending a message). The SMTP protocol is the fundamental
+basis on which messages are delivered all over the internet 7 days a week, 365
+days a year. For this reason it's the most "direct" method of sending messages
+you can use and it's the one that will give you the most power and feedback
+(such as delivery failures) when using Swift Mailer.
+
+Because SMTP is generally run as a remote service (i.e. you connect to it over
+the network/internet) it's extremely portable from server-to-server. You can
+easily store the SMTP server address and port number in a configuration file
+within your application and adjust the settings accordingly if the code is
+moved or if the SMTP server is changed.
+
+Some SMTP servers -- Google for example -- use encryption for security reasons.
+Swift Mailer supports using both SSL and TLS encryption settings.

+
+The SMTP Transport is easy to use. Most configuration options can be set with
+the constructor.
+
+To use the SMTP Transport you need to know which SMTP server your code needs
+to connect to. Ask your web host if you're not sure. Lots of people ask me who
+to connect to -- I really can't answer that since it's a setting that's
+extremely specific to your hosting environment.
+
+To use the SMTP Transport:
+
+* Call ``Swift_SmtpTransport::newInstance()`` with the SMTP server name and
+  optionally with a port number (defaults to 25).
+
+* Use the returned object to create the Mailer.
+
+A connection to the SMTP server will be established upon the first call to
+``send()``.
+
+.. code-block:: php
+
+    require_once 'lib/swift_required.php';
+
+    // Create the Transport
+    $transport = Swift_SmtpTransport::newInstance('smtp.example.org', 25);
+
+    // Create the Mailer using your created Transport
+    $mailer = Swift_Mailer::newInstance($transport);
+
+    /*
+    It's also possible to use multiple method calls
+
+    $transport = Swift_SmtpTransport::newInstance()
+      ->setHost('smtp.example.org')
+      ->setPort(25)
+      ;
+    */
+
+Encrypted SMTP
+^^^^^^^^^^^^^^
+
+You can use SSL or TLS encryption with the SMTP Transport by specifying it as
+a parameter or with a method call.
+
+To use encryption with the SMTP Transport:
+
+* Pass the encryption setting as a third parameter to
+  ``Swift_SmtpTransport::newInstance()``; or
+
+* Call the ``setEncryption()`` method on the Transport.
+
+A connection to the SMTP server will be established upon the first call to
+``send()``. The connection will be initiated with the correct encryption
+settings.
+
+.. note::
+
+    For SSL or TLS encryption to work your PHP installation must have
+    appropriate OpenSSL transports wrappers. You can check if "tls" and/or
+    "ssl" are present in your PHP installation by using the PHP function
+    ``stream_get_transports()``
+
+    .. code-block:: php
+
+        require_once 'lib/swift_required.php';
+
+        // Create the Transport
+        $transport = Swift_SmtpTransport::newInstance('smtp.example.org', 587, 'ssl');
+
+        // Create the Mailer using your created Transport
+        $mailer = Swift_Mailer::newInstance($transport);
+
+        /*
+        It's also possible to use multiple method calls
+
+        $transport = Swift_SmtpTransport::newInstance()
+          ->setHost('smtp.example.org')
+          ->setPort(587)
+          ->setEncryption('ssl')
+          ;
+        */
+
+SMTP with a Username and Password
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Some servers require authentication. You can provide a username and password
+with ``setUsername()`` and ``setPassword()`` methods.
+
+To use a username and password with the SMTP Transport:
+
+* Create the Transport with ``Swift_SmtpTransport::newInstance()``.
+
+* Call the ``setUsername()`` and ``setPassword()`` methods on the Transport.
+
+Your username and password will be used to authenticate upon first connect
+when ``send()`` are first used on the Mailer.
+
+If authentication fails, an Exception of type ``Swift_TransportException`` will
+be thrown.
+
+.. note::
+
+    If you need to know early whether or not authentication has failed and an
+    Exception is going to be thrown, call the ``start()`` method on the
+    created Transport.
+
+    .. code-block:: php
+
+        require_once 'lib/swift_required.php';
+
+        // Create the Transport the call setUsername() and setPassword()
+        $transport = Swift_SmtpTransport::newInstance('smtp.example.org', 25)
+          ->setUsername('username')
+          ->setPassword('password')
+          ;
+
+        // Create the Mailer using your created Transport
+        $mailer = Swift_Mailer::newInstance($transport);
+
+The Sendmail Transport
+......................
+
+The Sendmail Transport sends messages by communicating with a locally
+installed MTA -- such as ``sendmail``.
+
+The Sendmail Transport, ``Swift_SendmailTransport`` does not directly connect to
+any remote services. It is designed for Linux servers that have ``sendmail``
+installed. The Transport starts a local ``sendmail`` process and sends messages
+to it. Usually the ``sendmail`` process will respond quickly as it spools your
+messages to disk before sending them.
+
+The Transport is named the Sendmail Transport for historical reasons
+(``sendmail`` was the "standard" UNIX tool for sending e-mail for years). It
+will send messages using other transfer agents such as Exim or Postfix despite
+its name, provided they have the relevant sendmail wrappers so that they can be
+started with the correct command-line flags.
+
+It's a common misconception that because the Sendmail Transport returns a
+result very quickly it must therefore deliver messages to recipients quickly
+-- this is not true. It's not slow by any means, but it's certainly not
+faster than SMTP when it comes to getting messages to the intended recipients.
+This is because sendmail itself sends the messages over SMTP once they have
+been quickly spooled to disk.
+
+The Sendmail Transport has the potential to be just as smart of the SMTP
+Transport when it comes to notifying Swift Mailer about which recipients were
+rejected, but in reality the majority of locally installed ``sendmail``
+instances are not configured well enough to provide any useful feedback. As such
+Swift Mailer may report successful deliveries where they did in fact fail before
+they even left your server.
+
+You can run the Sendmail Transport in two different modes specified by command
+line flags:
+
+* "``-bs``" runs in SMTP mode so theoretically it will act like the SMTP
+  Transport
+
+* "``-t``" runs in piped mode with no feedback, but theoretically faster,
+  though not advised
+
+You can think of the Sendmail Transport as a sort of asynchronous SMTP Transport
+-- though if you have problems with delivery failures you should try using the
+SMTP Transport instead. Swift Mailer isn't doing the work here, it's simply
+passing the work to somebody else (i.e. ``sendmail``).
+
+Using the Sendmail Transport
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To use the Sendmail Transport you simply need to call
+``Swift_SendmailTransport::newInstance()`` with the command as a parameter.
+
+To use the Sendmail Transport you need to know where ``sendmail`` or another MTA
+exists on the server. Swift Mailer uses a default value of
+``/usr/sbin/sendmail``, which should work on most systems.
+
+You specify the entire command as a parameter (i.e. including the command line
+flags). Swift Mailer supports operational modes of "``-bs``" (default) and
+"``-t``".
+
+.. note::
+
+    If you run sendmail in "``-t``" mode you will get no feedback as to whether
+    or not sending has succeeded. Use "``-bs``" unless you have a reason not to.
+
+To use the Sendmail Transport:
+
+* Call ``Swift_SendmailTransport::newInstance()`` with the command, including
+  the correct command line flags. The default is to use ``/usr/sbin/sendmail
+  -bs`` if this is not specified.
+
+* Use the returned object to create the Mailer.
+
+A sendmail process will be started upon the first call to ``send()``. If the
+process cannot be started successfully an Exception of type
+``Swift_TransportException`` will be thrown.
+
+.. code-block:: php
+
+    require_once 'lib/swift_required.php';
+
+    // Create the Transport
+    $transport = Swift_SendmailTransport::newInstance('/usr/sbin/exim -bs');
+
+    // Create the Mailer using your created Transport
+    $mailer = Swift_Mailer::newInstance($transport);
+
+The Mail Transport
+..................
+
+The Mail Transport sends messages by delegating to PHP's internal
+``mail()`` function.
+
+In my experience -- and others' -- the ``mail()`` function is not particularly
+predictable, or helpful.
+
+Quite notably, the ``mail()`` function behaves entirely differently between
+Linux and Windows servers. On linux it uses ``sendmail``, but on Windows it uses
+SMTP.
+
+In order for the ``mail()`` function to even work at all ``php.ini`` needs to be
+configured correctly, specifying the location of sendmail or of an SMTP server.
+
+The problem with ``mail()`` is that it "tries" to simplify things to the point
+that it actually makes things more complex due to poor interface design. The
+developers of Swift Mailer have gone to a lot of effort to make the Mail
+Transport work with a reasonable degree of consistency.
+
+Serious drawbacks when using this Transport are:
+
+* Unpredictable message headers
+
+* Lack of feedback regarding delivery failures
+
+* Lack of support for several plugins that require real-time delivery feedback
+
+It's a last resort, and we say that with a passion!
+
+Available Methods for Sending Messages
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The Mailer class offers two methods for sending Messages -- ``send()``.
+Each behaves in a slightly different way.
+
+When a message is sent in Swift Mailer, the Mailer class communicates with
+whichever Transport class you have chosen to use.
+
+Each recipient in the message should either be accepted or rejected by the
+Transport. For example, if the domain name on the email address is not
+reachable the SMTP Transport may reject the address because it cannot process
+it. Whichever method you use -- ``send()`` -- Swift Mailer will return
+an integer indicating the number of accepted recipients.
+
+.. note::
+
+    It's possible to find out which recipients were rejected -- we'll cover that
+    later in this chapter.
+
+Using the ``send()`` Method
+...........................
+
+The ``send()`` method of the ``Swift_Mailer`` class sends a message using
+exactly the same logic as your Desktop mail client would use. Just pass it a
+Message and get a result.
+
+To send a Message with ``send()``:
+
+* Create a Transport from one of the provided Transports --
+  ``Swift_SmtpTransport``, ``Swift_SendmailTransport``,
+  or one of the aggregate Transports.
+
+* Create an instance of the ``Swift_Mailer`` class, using the Transport as
+  it's constructor parameter.
+
+* Create a Message.
+
+* Send the message via the ``send()`` method on the Mailer object.
+
+The message will be sent just like it would be sent if you used your mail
+client. An integer is returned which includes the number of successful
+recipients. If none of the recipients could be sent to then zero will be
+returned, which equates to a boolean ``false``. If you set two
+``To:`` recipients and three ``Bcc:`` recipients in the message and all of the
+recipients are delivered to successfully then the value 5 will be returned.
+
+.. code-block:: php
+
+    require_once 'lib/swift_required.php';
+
+    // Create the Transport
+    $transport = Swift_SmtpTransport::newInstance('localhost', 25);
+
+    // Create the Mailer using your created Transport
+    $mailer = Swift_Mailer::newInstance($transport);
+
+    // Create a message
+    $message = Swift_Message::newInstance('Wonderful Subject')
+      ->setFrom(array('john@doe.com' => 'John Doe'))
+      ->setTo(array('receiver@domain.org', 'other@domain.org' => 'A name'))
+      ->setBody('Here is the message itself')
+      ;
+
+    // Send the message
+    $numSent = $mailer->send($message);
+
+    printf("Sent %d messages\n", $numSent);
+
+    /* Note that often that only the boolean equivalent of the
+       return value is of concern (zero indicates FALSE)
+
+    if ($mailer->send($message))
+    {
+      echo "Sent\n";
+    }
+    else
+    {
+      echo "Failed\n";
+    }
+
+    */
+
+Sending Emails in Batch
+.......................
+
+If you want to send a separate message to each recipient so that only their
+own address shows up in the ``To:`` field, follow the following recipe:
+
+* Create a Transport from one of the provided Transports --
+  ``Swift_SmtpTransport``, ``Swift_SendmailTransport``,
+  or one of the aggregate Transports.
+
+* Create an instance of the ``Swift_Mailer`` class, using the Transport as
+  it's constructor parameter.
+
+* Create a Message.
+
+* Iterate over the recipients and send message via the ``send()`` method on
+  the Mailer object.
+
+Each recipient of the messages receives a different copy with only their own
+email address on the ``To:`` field.
+
+Make sure to add only valid email addresses as recipients. If you try to add an
+invalid email address with ``setTo()``, ``setCc()`` or ``setBcc()``, Swift
+Mailer will throw a ``Swift_RfcComplianceException``.
+
+If you add recipients automatically based on a data source that may contain
+invalid email addresses, you can prevent possible exceptions by validating the
+addresses using ``Swift_Validate::email($email)`` and only adding addresses
+that validate. Another way would be to wrap your ``setTo()``, ``setCc()`` and
+``setBcc()`` calls in a try-catch block and handle the
+``Swift_RfcComplianceException`` in the catch block.
+
+Handling invalid addresses properly is especially important when sending emails
+in large batches since a single invalid address might cause an unhandled
+exception and stop the execution or your script early.
+
+.. note::
+
+    In the following example, two emails are sent. One to each of
+    ``receiver@domain.org`` and ``other@domain.org``. These recipients will
+    not be aware of each other.
+
+    .. code-block:: php
+
+        require_once 'lib/swift_required.php';
+
+        // Create the Transport
+        $transport = Swift_SmtpTransport::newInstance('localhost', 25);
+
+        // Create the Mailer using your created Transport
+        $mailer = Swift_Mailer::newInstance($transport);
+
+        // Create a message
+        $message = Swift_Message::newInstance('Wonderful Subject')
+          ->setFrom(array('john@doe.com' => 'John Doe'))
+          ->setBody('Here is the message itself')
+          ;
+
+        // Send the message
+        $failedRecipients = array();
+        $numSent = 0;
+        $to = array('receiver@domain.org', 'other@domain.org' => 'A name');
+
+        foreach ($to as $address => $name)
+        {
+          if (is_int($address)) {
+            $message->setTo($name);
+          } else {
+            $message->setTo(array($address => $name));
+          }
+
+          $numSent += $mailer->send($message, $failedRecipients);
+        }
+
+        printf("Sent %d messages\n", $numSent);
+
+Finding out Rejected Addresses
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It's possible to get a list of addresses that were rejected by the Transport
+by using a by-reference parameter to ``send()``.
+
+As Swift Mailer attempts to send the message to each address given to it, if a
+recipient is rejected it will be added to the array. You can pass an existing
+array, otherwise one will be created by-reference.
+
+Collecting the list of recipients that were rejected can be useful in
+circumstances where you need to "prune" a mailing list for example when some
+addresses cannot be delivered to.
+
+Getting Failures By-reference
+.............................
+
+Collecting delivery failures by-reference with the ``send()`` method is as
+simple as passing a variable name to the method call.
+
+To get failed recipients by-reference:
+
+* Pass a by-reference variable name to the ``send()`` method of the Mailer
+  class.
+
+If the Transport rejects any of the recipients, the culprit addresses will be
+added to the array provided by-reference.
+
+.. note::
+
+    If the variable name does not yet exist, it will be initialized as an
+    empty array and then failures will be added to that array. If the variable
+    already exists it will be type-cast to an array and failures will be added
+    to it.
+
+    .. code-block:: php
+
+        $mailer = Swift_Mailer::newInstance( ... );
+
+        $message = Swift_Message::newInstance( ... )
+          ->setFrom( ... )
+          ->setTo(array(
+            'receiver@bad-domain.org' => 'Receiver Name',
+            'other@domain.org' => 'A name',
+            'other-receiver@bad-domain.org' => 'Other Name'
+          ))
+          ->setBody( ... )
+          ;
+
+        // Pass a variable name to the send() method
+        if (!$mailer->send($message, $failures))
+        {
+          echo "Failures:";
+          print_r($failures);
+        }
+
+        /*
+        Failures:
+        Array (
+          0 => receiver@bad-domain.org,
+          1 => other-receiver@bad-domain.org
+        )
+        */

+ISO-2022-JPは、インターネット上(特に電子メール)などで使われる日本の文字用の文字符号化方式。ISO/IEC 2022のエスケープシーケンスを利用して文字集合を切り替える7ビットのコードであることを特徴とする (アナウンス機能のエスケープシーケンスは省略される)。俗に「JISコード」と呼ばれることもある。
+
+概要
+日本語表記への利用が想定されている文字コードであり、日本語の利用されるネットワークにおいて、日本の規格を応用したものである。また文字集合としては、日本語で用いられる漢字、ひらがな、カタカナはもちろん、ラテン文字、ギリシア文字、キリル文字なども含んでおり、学術や産業の分野での利用も考慮たものとなっている。規格名に、ISOの日本語の言語コードであるjaではなく、国・地域名コードのJPが示されているゆえんである。
+文字集合としてJIS X 0201のC0集合（制御文字）、JIS X 0201のラテン文字集合、ISO 646の国際基準版図形文字、JIS X 0208の1978年版（JIS C 6226-1978）と1983年および1990年版が利用できる。JIS X 0201の片仮名文字集合は利用できない。1986年以降、日本の電子メールで用いられてきたJUNETコードを、村井純・Mark Crispin・Erik van der Poelが1993年にRFC化したもの(RFC 1468)。後にJIS X 0208:1997の附属書2としてJISに規定された。MIMEにおける文字符号化方式の識別用の名前として IANA に登録されている。
+なお、符号化の仕様についてはISO/IEC 2022#ISO-2022-JPも参照。
+
+ISO-2022-JPと非標準的拡張使用
+「JISコード」（または「ISO-2022-JP」）というコード名の規定下では、その仕様通りの使用が求められる。しかし、Windows OS上では、実際にはCP932コード (MicrosoftによるShift JISを拡張した亜種。ISO-2022-JP規定外文字が追加されている。）による独自拡張（の文字）を断りなく使うアプリケーションが多い。この例としてInternet ExplorerやOutlook Expressがある。また、EmEditor、秀丸エディタやThunderbirdのようなMicrosoft社以外のWindowsアプリケーションでも同様の場合がある。この場合、ISO-2022-JPの範囲外の文字を使ってしまうと、異なる製品間では未定義不明文字として認識されるか、もしくは文字化けを起こす原因となる。そのため、Windows用の電子メールクライアントであっても独自拡張の文字を使用すると警告を出したり、あえて使えないように制限しているものも存在する。さらにはISO-2022-JPの範囲内であってもCP932は非標準文字（FULLWIDTH TILDE等）を持つので文字化けの原因になり得る。
+また、符号化方式名をISO-2022-JPとしているのに、文字集合としてはJIS X 0212 (いわゆる補助漢字) やJIS X 0201の片仮名文字集合 (いわゆる半角カナ) をも符号化している例があるが、ISO-2022-JPではこれらの文字を許容していない。これらの符号化は独自拡張の実装であり、中にはISO/IEC 2022の仕様に準拠すらしていないものもある[2]。従って受信側の電子メールクライアントがこれらの独自拡張に対応していない場合、その文字あるいはその文字を含む行、時にはテキスト全体が文字化けすることがある。

+
+         Once the server has sent the welcoming message and the client has
+         received it, the client normally sends the EHLO command to the
+         server, indicating the client's identity.  In addition to opening the
+         session, use of EHLO indicates that the client is able to process
+         service extensions and requests that the server provide a list of the
+         extensions it supports.  Older SMTP systems which are unable to
+         support service extensions and contemporary clients which do not
+         require service extensions in the mail session being initiated, MAY
+         use HELO instead of EHLO.  Servers MUST NOT return the extended
+         EHLO-style response to a HELO command.  For a particular connection
+         attempt, if the server returns a "command not recognized" response to
+         EHLO, the client SHOULD be able to fall back and send HELO.
+
+         In the EHLO command the host sending the command identifies itself;
+         the command may be interpreted as saying "Hello, I am <domain>" (and,
+         in the case of EHLO, "and I support service extension requests").

+     Addresses that do not appear in the message headers may appear in the

+     the full set of RCPT command arguments into the headers, either as
+     part of trace headers or as informational or private-extension
+     headers.  Since this rule is often violated in practice, and cannot
+     be enforced, sending SMTP systems that are aware of "bcc" use MAY
+     find it helpful to send each blind copy as a separate message
+     transaction containing only a single RCPT command.

+         received it, the client normally sends the EHLO command to the
+         server, indicating the client's identity.  In addition to opening the

+         service extensions and requests that the server provide a list of the
+         extensions it supports.  Older SMTP systems which are unable to
+         support service extensions and contemporary clients which do not
+         require service extensions in the mail session being initiated, MAY
+         use HELO instead of EHLO.  Servers MUST NOT return the extended

+ * removed `BCResourceInterfaceChecker` class
+ * removed `ResourceInterface::getResource()` method
+
+2.8.0
+-----
+
+The edge case of defining just one value for nodes of type Enum is now allowed:
+
+```php
+$rootNode
+    ->children()
+        ->enumNode('variable')
+            ->values(array('value'))
+        ->end()
+    ->end()
+;
+```
+
+Before: `InvalidArgumentException` (variable must contain at least two
+distinct elements).
+After: the code will work as expected and it will restrict the values of the
+`variable` option to just `value`.
+
+ * deprecated the `ResourceInterface::isFresh()` method. If you implement custom resource types and they
+   can be validated that way, make them implement the new `SelfCheckingResourceInterface`.
+ * deprecated the getResource() method in ResourceInterface. You can still call this method
+   on concrete classes implementing the interface, but it does not make sense at the interface
+   level as you need to know about the particular type of resource at hand to understand the
+   semantics of the returned value.
+
+2.7.0
+-----
+
+ * added `ConfigCacheInterface`, `ConfigCacheFactoryInterface` and a basic `ConfigCacheFactory`
+   implementation to delegate creation of ConfigCache instances
+
+2.2.0
+-----
+
+ * added `ArrayNodeDefinition::canBeEnabled()` and `ArrayNodeDefinition::canBeDisabled()`
+   to ease configuration when some sections are respectively disabled / enabled
+   by default.
+ * added a `normalizeKeys()` method for array nodes (to avoid key normalization)
+ * added numerical type handling for config definitions
+ * added convenience methods for optional configuration sections to `ArrayNodeDefinition`
+ * added a utils class for XML manipulations
+
+2.1.0
+-----
+
+ * added a way to add documentation on configuration
+ * implemented `Serializable` on resources
+ * `LoaderResolverInterface` is now used instead of `LoaderResolver` for type
+   hinting

+-----
+
+ * added a Process helper
+ * added a DebugFormatter helper
+
+2.5.0
+-----
+
+ * deprecated the dialog helper (use the question helper instead)

+2.1.0
+-----
+
+ * added ConsoleOutputInterface
+ * added the possibility to disable a command (Command::isEnabled())
+ * added suggestions when a command does not exist
+ * added a --raw option to the list command
+ * added support for STDERR in the console output class (errors are now sent
+   to STDERR)
+ * made the defaults (helper set, commands, input definition) in Application
+   more easily customizable
+ * added support for the shell even if readline is not available
+ * added support for process isolation in Symfony shell via
+   `--process-isolation` switch

+CHANGELOG
+=========
+
+4.1.0
+-----
+
+ * The `FileDumper::setBackup()` method is deprecated.
+ * The `TranslationWriter::disableBackup()` method is deprecated.
+ * The `XliffFileDumper` will write "name" on the "unit" node when dumping XLIFF 2.0.
+
+4.0.0
+-----
+
+ * removed the backup feature of the `FileDumper` class
+ * removed `TranslationWriter::writeTranslations()` method
+ * removed support for passing `MessageSelector` instances to the constructor of the `Translator` class
+
+3.4.0
+-----
+
+ * Added `TranslationDumperPass`
+ * Added `TranslationExtractorPass`
+ * Added `TranslatorPass`
+ * Added `TranslationReader` and `TranslationReaderInterface`
+ * Added `<notes>` section to the Xliff 2.0 dumper.
+ * Improved Xliff 2.0 loader to load `<notes>` section.
+ * Added `TranslationWriterInterface`
+ * Deprecated `TranslationWriter::writeTranslations` in favor of `TranslationWriter::write`
+ * added support for adding custom message formatter and decoupling the default one.
+ * Added `PhpExtractor`
+ * Added `PhpStringTokenParser`
+
+3.2.0
+-----
+
+ * Added support for escaping `|` in plural translations with double pipe.
+
+3.1.0

+
+3.0.0
+-----
+
+ * removed `FileDumper::format()` method.

+
+2.8.0
+-----
+
+ * deprecated FileDumper::format(), overwrite FileDumper::formatCatalogue() instead.
+ * deprecated Translator::getMessages(), rely on TranslatorBagInterface::getCatalogue() instead.

+ * added options `as_tree`, `inline` to YamlFileDumper
+ * added support for XLIFF 2.0.
+ * added support for XLIFF target and tool attributes.
+ * added message parameters to DataCollectorTranslator.
+ * [DEPRECATION] The `DiffOperation` class has been deprecated and
+   will be removed in Symfony 3.0, since its operation has nothing to do with 'diff',
+   so the class name is misleading. The `TargetOperation` class should be used for

+-----
+
+ * QtTranslationsLoader class renamed to QtFileLoader. QtTranslationsLoader is deprecated and will be removed in 2.3.

+ * changed the exception class thrown by some load() methods from \RuntimeException to \InvalidArgumentException
+   (IcuDatFileLoader, IcuResFileLoader and QtFileLoader)
+
+2.1.0
+-----

+ *
+ * When you make another call to the validator, while the validation is in

+CHANGELOG
+=========
+
+4.0.0
+-----
+
+ * The behavior of the non-specific tag `!` is changed and now forces
+   non-evaluating your values.
+ * complex mappings will throw a `ParseException`
+ * support for the comma as a group separator for floats has been dropped, use
+   the underscore instead
+ * support for the `!!php/object` tag has been dropped, use the `!php/object`
+   tag instead
+ * duplicate mapping keys throw a `ParseException`
+ * non-string mapping keys throw a `ParseException`, use the `Yaml::PARSE_KEYS_AS_STRINGS`
+   flag to cast them to strings
+ * `%` at the beginning of an unquoted string throw a `ParseException`
+ * mappings with a colon (`:`) that is not followed by a whitespace throw a
+   `ParseException`
+ * the `Dumper::setIndentation()` method has been removed
+ * being able to pass boolean options to the `Yaml::parse()`, `Yaml::dump()`,
+   `Parser::parse()`, and `Dumper::dump()` methods to configure the behavior of
+   the parser and dumper is no longer supported, pass bitmask flags instead
+ * the constructor arguments of the `Parser` class have been removed
+ * the `Inline` class is internal and no longer part of the BC promise
+ * removed support for the `!str` tag, use the `!!str` tag instead
+ * added support for tagged scalars.
+
+   ```yml
+   Yaml::parse('!foo bar', Yaml::PARSE_CUSTOM_TAGS);
+   // returns TaggedValue('foo', 'bar');
+   ```
+
+3.4.0
+-----
+
+ * added support for parsing YAML files using the `Yaml::parseFile()` or `Parser::parseFile()` method
+
+ * the `Dumper`, `Parser`, and `Yaml` classes are marked as final
+
+ * Deprecated the `!php/object:` tag which will be replaced by the
+   `!php/object` tag (without the colon) in 4.0.
+
+ * Deprecated the `!php/const:` tag which will be replaced by the
+   `!php/const` tag (without the colon) in 4.0.
+
+ * Support for the `!str` tag is deprecated, use the `!!str` tag instead.
+
+ * Deprecated using the non-specific tag `!` as its behavior will change in 4.0.
+   It will force non-evaluating your values in 4.0. Use plain integers or `!!float` instead.
+
+3.3.0
+-----
+
+ * Starting an unquoted string with a question mark followed by a space is
+   deprecated and will throw a `ParseException` in Symfony 4.0.
+
+ * Deprecated support for implicitly parsing non-string mapping keys as strings.
+   Mapping keys that are no strings will lead to a `ParseException` in Symfony
+   4.0. Use quotes to opt-in for keys to be parsed as strings.
+
+   Before:
+
+   ```php
+   $yaml = <<<YAML
+   null: null key
+   true: boolean true
+   2.0: float key
+   YAML;
+
+   Yaml::parse($yaml);
+   ```
+
+   After:
+
+   ```php
+
+   $yaml = <<<YAML
+   "null": null key
+   "true": boolean true
+   "2.0": float key
+   YAML;
+
+   Yaml::parse($yaml);
+   ```
+
+ * Omitted mapping values will be parsed as `null`.
+
+ * Omitting the key of a mapping is deprecated and will throw a `ParseException` in Symfony 4.0.
+
+ * Added support for dumping empty PHP arrays as YAML sequences:
+
+   ```php
+   Yaml::dump([], 0, 0, Yaml::DUMP_EMPTY_ARRAY_AS_SEQUENCE);
+   ```
+
+3.2.0
+-----
+
+ * Mappings with a colon (`:`) that is not followed by a whitespace are deprecated
+   when the mapping key is not quoted and will lead to a `ParseException` in
+   Symfony 4.0 (e.g. `foo:bar` must be `foo: bar`).
+
+ * Added support for parsing PHP constants:
+
+   ```php
+   Yaml::parse('!php/const:PHP_INT_MAX', Yaml::PARSE_CONSTANT);
+   ```
+
+ * Support for silently ignoring duplicate mapping keys in YAML has been
+   deprecated and will lead to a `ParseException` in Symfony 4.0.
+
+3.1.0
+-----
+
+ * Added support to dump `stdClass` and `ArrayAccess` objects as YAML mappings
+   through the `Yaml::DUMP_OBJECT_AS_MAP` flag.
+
+ * Strings that are not UTF-8 encoded will be dumped as base64 encoded binary
+   data.
+
+ * Added support for dumping multi line strings as literal blocks.
+
+ * Added support for parsing base64 encoded binary data when they are tagged
+   with the `!!binary` tag.
+
+ * Added support for parsing timestamps as `\DateTime` objects:
+
+   ```php
+   Yaml::parse('2001-12-15 21:59:43.10 -5', Yaml::PARSE_DATETIME);
+   ```
+
+ * `\DateTime` and `\DateTimeImmutable` objects are dumped as YAML timestamps.
+
+ * Deprecated usage of `%` at the beginning of an unquoted string.
+
+ * Added support for customizing the YAML parser behavior through an optional bit field:
+
+   ```php
+   Yaml::parse('{ "foo": "bar", "fiz": "cat" }', Yaml::PARSE_EXCEPTION_ON_INVALID_TYPE | Yaml::PARSE_OBJECT | Yaml::PARSE_OBJECT_FOR_MAP);
+   ```
+
+ * Added support for customizing the dumped YAML string through an optional bit field:
+
+   ```php
+   Yaml::dump(array('foo' => new A(), 'bar' => 1), 0, 0, Yaml::DUMP_EXCEPTION_ON_INVALID_TYPE | Yaml::DUMP_OBJECT);
+   ```
+
+3.0.0
+-----
+
+ * Yaml::parse() now throws an exception when a blackslash is not escaped
+   in double-quoted strings
+
+2.8.0
+-----
+
+ * Deprecated usage of a colon in an unquoted mapping value
+ * Deprecated usage of @, \`, | and > at the beginning of an unquoted string
+ * When surrounding strings with double-quotes, you must now escape `\` characters. Not
+   escaping those characters (when surrounded by double-quotes) is deprecated.
+
+   Before:
+
+   ```yml
+   class: "Foo\Var"
+   ```
+
+   After:
+
+   ```yml
+   class: "Foo\\Var"
+   ```
+
+2.1.0
+-----
+
+ * Yaml::parse() does not evaluate loaded files as PHP files by default
+   anymore (call Yaml::enablePhpParsing() to get back the old behavior)

+
+Backward incompatibilities:
+
+ * The Escaper extension is enabled by default, which means that all displayed
+   variables are now automatically escaped. You can revert to the previous
+   behavior by removing the extension via $env->removeExtension('escaper')
+   or just set the 'autoescape' option to 'false'.

+
+* 0.9.9 (2010-11-28)

+     {{ foo|odd }} must now be written {{ foo is odd }}
+ * the "safe" filter has been renamed to "raw"

+ * the include tag now merges the passed variables with the current context by default
+   (the old behavior is still possible by adding the "only" keyword)
+ * moved Exceptions to Twig_Error_* (Twig_SyntaxError/Twig_RuntimeError are now Twig_Error_Syntax/Twig_Error_Runtime)
+ * removed support for {{ 1 < i < 3 }} (use {{ i > 1 and i < 3 }} instead)

+ * fixed unary expressions ({{ not(1 or 0) }})
+ * fixed child templates (with an extend tag) that uses one or more imports
+ * added support for {{ 1 not in [2, 3] }} (more readable than the current {{ not (1 in [2, 3]) }})

+ * fixed Twig_Template::getAttribute() for protected properties
+
+* 0.9.8 (2010-06-28)
+
+Backward incompatibilities:

+
+As for any new release, don't forget to remove all cached templates after
+upgrading.
+
+If you have defined custom filters, you MUST upgrade them for this release. To
+upgrade, replace "array" with "new Twig_Filter_Function", and replace the
+environment constant by the "needs_environment" option:
+
+  // before
+  'even'   => array('twig_is_even_filter', false),
+  'escape' => array('twig_escape_filter', true),
+
+  // after
+  'even'   => new Twig_Filter_Function('twig_is_even_filter'),
+  'escape' => new Twig_Filter_Function('twig_escape_filter', array('needs_environment' => true)),
+
+If you have created NodeTransformer classes, you will need to upgrade them to
+the new interface (please note that the interface is not yet considered
+stable).

+ * added the .. operator (as a syntactic sugar for the range filter when the step is 1)
+ * added the in operator (as a syntactic sugar for the in filter)
+ * added the following filters in the Core extension: in, range
+ * added support for arrays (same behavior as in PHP, a mix between lists and dictionaries, arrays and hashes)
+ * enhanced some error messages to provide better feedback in case of parsing errors
+
+* 0.9.4 (2009-12-02)
+
+If you have custom loaders, you MUST upgrade them for this release: The
+Twig_Loader base class has been removed, and the Twig_LoaderInterface has also
+been changed (see the source code for more information or the documentation).
+
+ * added support for DateTime instances for the date filter
+ * fixed loop.last when the array only has one item
+ * made it possible to insert newlines in tag and variable blocks

+ * refactored loaders
+
+* 0.9.3 (2009-11-11)
+
+This release is NOT backward compatible with the previous releases.
+
+  The loaders do not take the cache and autoReload arguments anymore. Instead,
+  the Twig_Environment class has two new options: cache and auto_reload.
+  Upgrading your code means changing this kind of code:
+
+      $loader = new Twig_Loader_Filesystem('/path/to/templates', '/path/to/compilation_cache', true);
+      $twig = new Twig_Environment($loader);
+
+  to something like this:
+
+      $loader = new Twig_Loader_Filesystem('/path/to/templates');
+      $twig = new Twig_Environment($loader, array(
+        'cache' => '/path/to/compilation_cache',
+        'auto_reload' => true,
+      ));
+
+ * deprecated the "items" filter as it is not needed anymore

+ * fixed bug when \ was used in HTML
+
+* 0.9.2 (2009-10-29)

+Twig, the flexible, fast, and secure template language for PHP
+==============================================================
+
+Twig is a template language for PHP, released under the new BSD license (code
+and documentation).
+
+Twig uses a syntax similar to the Django and Jinja template languages which
+inspired the Twig runtime environment.

+Extending Twig
+==============
+
+Twig can be extended in many ways; you can add extra tags, filters, tests,
+operators, global variables, and functions. You can even extend the parser
+itself with node visitors.
+
+.. note::
+
+    The first section of this chapter describes how to extend Twig easily. If
+    you want to reuse your changes in different projects or if you want to
+    share them with others, you should then create an extension as described
+    in the following section.
+
+.. caution::
+
+    When extending Twig without creating an extension, Twig won't be able to
+    recompile your templates when the PHP code is updated. To see your changes
+    in real-time, either disable template caching or package your code into an
+    extension (see the next section of this chapter).
+
+Before extending Twig, you must understand the differences between all the
+different possible extension points and when to use them.
+
+First, remember that Twig has two main language constructs:
+
+* ``{{ }}``: used to print the result of an expression evaluation;
+
+* ``{% %}``: used to execute statements.
+
+To understand why Twig exposes so many extension points, let's see how to
+implement a *Lorem ipsum* generator (it needs to know the number of words to
+generate).
+
+You can use a ``lipsum`` *tag*:
+
+.. code-block:: jinja
+
+    {% lipsum 40 %}
+
+That works, but using a tag for ``lipsum`` is not a good idea for at least
+three main reasons:
+
+* ``lipsum`` is not a language construct;
+* The tag outputs something;
+* The tag is not flexible as you cannot use it in an expression:
+
+  .. code-block:: jinja
+
+      {{ 'some text' ~ {% lipsum 40 %} ~ 'some more text' }}
+
+In fact, you rarely need to create tags; and that's good news because tags are
+the most complex extension point of Twig.
+
+Now, let's use a ``lipsum`` *filter*:
+
+.. code-block:: jinja
+
+    {{ 40|lipsum }}
+
+Again, it works, but it looks weird. A filter transforms the passed value to
+something else but here we use the value to indicate the number of words to
+generate (so, ``40`` is an argument of the filter, not the value we want to
+transform).
+
+Next, let's use a ``lipsum`` *function*:
+
+.. code-block:: jinja
+
+    {{ lipsum(40) }}
+
+Here we go. For this specific example, the creation of a function is the
+extension point to use. And you can use it anywhere an expression is accepted:
+
+.. code-block:: jinja
+
+    {{ 'some text' ~ lipsum(40) ~ 'some more text' }}
+
+    {% set lipsum = lipsum(40) %}
+
+Last but not the least, you can also use a *global* object with a method able
+to generate lorem ipsum text:
+
+.. code-block:: jinja
+
+    {{ text.lipsum(40) }}
+
+As a rule of thumb, use functions for frequently used features and global
+objects for everything else.
+
+Keep in mind the following when you want to extend Twig:
+
+========== ========================== ========== =========================
+What?      Implementation difficulty? How often? When?
+========== ========================== ========== =========================
+*macro*    trivial                    frequent   Content generation
+*global*   trivial                    frequent   Helper object
+*function* trivial                    frequent   Content generation
+*filter*   trivial                    frequent   Value transformation
+*tag*      complex                    rare       DSL language construct
+*test*     trivial                    rare       Boolean decision
+*operator* trivial                    rare       Values transformation
+========== ========================== ========== =========================
+
+Globals
+-------
+
+A global variable is like any other template variable, except that it's
+available in all templates and macros::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addGlobal('text', new Text());
+
+You can then use the ``text`` variable anywhere in a template:
+
+.. code-block:: jinja
+
+    {{ text.lipsum(40) }}
+
+Filters
+-------
+
+Creating a filter is as simple as associating a name with a PHP callable::
+
+    // an anonymous function
+    $filter = new Twig_Filter('rot13', function ($string) {
+        return str_rot13($string);
+    });
+
+    // or a simple PHP function
+    $filter = new Twig_Filter('rot13', 'str_rot13');
+
+    // or a class static method
+    $filter = new Twig_Filter('rot13', array('SomeClass', 'rot13Filter'));
+    $filter = new Twig_Filter('rot13', 'SomeClass::rot13Filter');
+
+    // or a class method
+    $filter = new Twig_Filter('rot13', array($this, 'rot13Filter'));
+    // the one below needs a runtime implementation (see below for more information)
+    $filter = new Twig_Filter('rot13', array('SomeClass', 'rot13Filter'));
+
+The first argument passed to the ``Twig_Filter`` constructor is the name of the
+filter you will use in templates and the second one is the PHP callable to
+associate with it.
+
+Then, add the filter to your Twig environment::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addFilter($filter);
+
+And here is how to use it in a template:
+
+.. code-block:: jinja
+
+    {{ 'Twig'|rot13 }}
+
+    {# will output Gjvt #}
+
+When called by Twig, the PHP callable receives the left side of the filter
+(before the pipe ``|``) as the first argument and the extra arguments passed
+to the filter (within parentheses ``()``) as extra arguments.
+
+For instance, the following code:
+
+.. code-block:: jinja
+
+    {{ 'TWIG'|lower }}
+    {{ now|date('d/m/Y') }}
+
+is compiled to something like the following::
+
+    <?php echo strtolower('TWIG') ?>
+    <?php echo twig_date_format_filter($now, 'd/m/Y') ?>
+
+The ``Twig_Filter`` class takes an array of options as its last argument::
+
+    $filter = new Twig_Filter('rot13', 'str_rot13', $options);
+
+Environment-aware Filters
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to access the current environment instance in your filter, set the
+``needs_environment`` option to ``true``; Twig will pass the current
+environment as the first argument to the filter call::
+
+    $filter = new Twig_Filter('rot13', function (Twig_Environment $env, $string) {
+        // get the current charset for instance
+        $charset = $env->getCharset();
+
+        return str_rot13($string);
+    }, array('needs_environment' => true));
+
+Context-aware Filters
+~~~~~~~~~~~~~~~~~~~~~
+
+If you want to access the current context in your filter, set the
+``needs_context`` option to ``true``; Twig will pass the current context as
+the first argument to the filter call (or the second one if
+``needs_environment`` is also set to ``true``)::
+
+    $filter = new Twig_Filter('rot13', function ($context, $string) {
+        // ...
+    }, array('needs_context' => true));
+
+    $filter = new Twig_Filter('rot13', function (Twig_Environment $env, $context, $string) {
+        // ...
+    }, array('needs_context' => true, 'needs_environment' => true));
+
+Automatic Escaping
+~~~~~~~~~~~~~~~~~~
+
+If automatic escaping is enabled, the output of the filter may be escaped
+before printing. If your filter acts as an escaper (or explicitly outputs HTML
+or JavaScript code), you will want the raw output to be printed. In such a
+case, set the ``is_safe`` option::
+
+    $filter = new Twig_Filter('nl2br', 'nl2br', array('is_safe' => array('html')));
+
+Some filters may need to work on input that is already escaped or safe, for
+example when adding (safe) HTML tags to originally unsafe output. In such a
+case, set the ``pre_escape`` option to escape the input data before it is run
+through your filter::
+
+    $filter = new Twig_Filter('somefilter', 'somefilter', array('pre_escape' => 'html', 'is_safe' => array('html')));
+
+Variadic Filters
+~~~~~~~~~~~~~~~~
+
+When a filter should accept an arbitrary number of arguments, set the
+``is_variadic`` option to ``true``; Twig will pass the extra arguments as the
+last argument to the filter call as an array::
+
+    $filter = new Twig_Filter('thumbnail', function ($file, array $options = array()) {
+        // ...
+    }, array('is_variadic' => true));
+
+Be warned that named arguments passed to a variadic filter cannot be checked
+for validity as they will automatically end up in the option array.
+
+Dynamic Filters
+~~~~~~~~~~~~~~~
+
+A filter name containing the special ``*`` character is a dynamic filter as
+the ``*`` can be any string::
+
+    $filter = new Twig_Filter('*_path', function ($name, $arguments) {
+        // ...
+    });
+
+The following filters will be matched by the above defined dynamic filter:
+
+* ``product_path``
+* ``category_path``
+
+A dynamic filter can define more than one dynamic parts::
+
+    $filter = new Twig_Filter('*_path_*', function ($name, $suffix, $arguments) {
+        // ...
+    });
+
+The filter will receive all dynamic part values before the normal filter
+arguments, but after the environment and the context. For instance, a call to
+``'foo'|a_path_b()`` will result in the following arguments to be passed to
+the filter: ``('a', 'b', 'foo')``.
+
+Deprecated Filters
+~~~~~~~~~~~~~~~~~~
+
+You can mark a filter as being deprecated by setting the ``deprecated`` option
+to ``true``. You can also give an alternative filter that replaces the
+deprecated one when that makes sense::
+
+    $filter = new Twig_Filter('obsolete', function () {
+        // ...
+    }, array('deprecated' => true, 'alternative' => 'new_one'));
+
+When a filter is deprecated, Twig emits a deprecation notice when compiling a
+template using it. See :ref:`deprecation-notices` for more information.
+
+Functions
+---------
+
+Functions are defined in the exact same way as filters, but you need to create
+an instance of ``Twig_Function``::
+
+    $twig = new Twig_Environment($loader);
+    $function = new Twig_Function('function_name', function () {
+        // ...
+    });
+    $twig->addFunction($function);
+
+Functions support the same features as filters, except for the ``pre_escape``
+and ``preserves_safety`` options.
+
+Tests
+-----
+
+Tests are defined in the exact same way as filters and functions, but you need
+to create an instance of ``Twig_Test``::
+
+    $twig = new Twig_Environment($loader);
+    $test = new Twig_Test('test_name', function () {
+        // ...
+    });
+    $twig->addTest($test);
+
+Tests allow you to create custom application specific logic for evaluating
+boolean conditions. As a simple example, let's create a Twig test that checks if
+objects are 'red'::
+
+    $twig = new Twig_Environment($loader);
+    $test = new Twig_Test('red', function ($value) {
+        if (isset($value->color) && $value->color == 'red') {
+            return true;
+        }
+        if (isset($value->paint) && $value->paint == 'red') {
+            return true;
+        }
+        return false;
+    });
+    $twig->addTest($test);
+
+Test functions should always return true/false.
+
+When creating tests you can use the ``node_class`` option to provide custom test
+compilation. This is useful if your test can be compiled into PHP primitives.
+This is used by many of the tests built into Twig::
+
+    $twig = new Twig_Environment($loader);
+    $test = new Twig_Test(
+        'odd',
+        null,
+        array('node_class' => 'Twig_Node_Expression_Test_Odd'));
+    $twig->addTest($test);
+
+    class Twig_Node_Expression_Test_Odd extends Twig_Node_Expression_Test
+    {
+        public function compile(Twig_Compiler $compiler)
+        {
+            $compiler
+                ->raw('(')
+                ->subcompile($this->getNode('node'))
+                ->raw(' % 2 == 1')
+                ->raw(')')
+            ;
+        }
+    }
+
+The above example shows how you can create tests that use a node class. The
+node class has access to one sub-node called 'node'. This sub-node contains the
+value that is being tested. When the ``odd`` filter is used in code such as:
+
+.. code-block:: jinja
+
+    {% if my_value is odd %}
+
+The ``node`` sub-node will contain an expression of ``my_value``. Node-based
+tests also have access to the ``arguments`` node. This node will contain the
+various other arguments that have been provided to your test.
+
+If you want to pass a variable number of positional or named arguments to the
+test, set the ``is_variadic`` option to ``true``. Tests also support dynamic
+name feature as filters and functions.
+
+Tags
+----
+
+One of the most exciting features of a template engine like Twig is the
+possibility to define new language constructs. This is also the most complex
+feature as you need to understand how Twig's internals work.
+
+Let's create a simple ``set`` tag that allows the definition of simple
+variables from within a template. The tag can be used like follows:
+
+.. code-block:: jinja
+
+    {% set name = "value" %}
+
+    {{ name }}
+
+    {# should output value #}
+
+.. note::
+
+    The ``set`` tag is part of the Core extension and as such is always
+    available. The built-in version is slightly more powerful and supports
+    multiple assignments by default (cf. the template designers chapter for
+    more information).
+
+Three steps are needed to define a new tag:
+
+* Defining a Token Parser class (responsible for parsing the template code);
+
+* Defining a Node class (responsible for converting the parsed code to PHP);
+
+* Registering the tag.
+
+Registering a new tag
+~~~~~~~~~~~~~~~~~~~~~
+
+Adding a tag is as simple as calling the ``addTokenParser`` method on the
+``Twig_Environment`` instance::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addTokenParser(new Project_Set_TokenParser());
+
+Defining a Token Parser
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Now, let's see the actual code of this class::
+
+    class Project_Set_TokenParser extends Twig_TokenParser
+    {
+        public function parse(Twig_Token $token)
+        {
+            $parser = $this->parser;
+            $stream = $parser->getStream();
+
+            $name = $stream->expect(Twig_Token::NAME_TYPE)->getValue();
+            $stream->expect(Twig_Token::OPERATOR_TYPE, '=');
+            $value = $parser->getExpressionParser()->parseExpression();
+            $stream->expect(Twig_Token::BLOCK_END_TYPE);
+
+            return new Project_Set_Node($name, $value, $token->getLine(), $this->getTag());
+        }
+
+        public function getTag()
+        {
+            return 'set';
+        }
+    }
+
+The ``getTag()`` method must return the tag we want to parse, here ``set``.
+
+The ``parse()`` method is invoked whenever the parser encounters a ``set``
+tag. It should return a ``Twig_Node`` instance that represents the node (the
+``Project_Set_Node`` calls creating is explained in the next section).
+
+The parsing process is simplified thanks to a bunch of methods you can call
+from the token stream (``$this->parser->getStream()``):
+
+* ``getCurrent()``: Gets the current token in the stream.
+
+* ``next()``: Moves to the next token in the stream, *but returns the old one*.
+
+* ``test($type)``, ``test($value)`` or ``test($type, $value)``: Determines whether
+  the current token is of a particular type or value (or both). The value may be an
+  array of several possible values.
+
+* ``expect($type[, $value[, $message]])``: If the current token isn't of the given
+  type/value a syntax error is thrown. Otherwise, if the type and value are correct,
+  the token is returned and the stream moves to the next token.
+
+* ``look()``: Looks at the next token without consuming it.
+
+Parsing expressions is done by calling the ``parseExpression()`` like we did for
+the ``set`` tag.
+
+.. tip::
+
+    Reading the existing ``TokenParser`` classes is the best way to learn all
+    the nitty-gritty details of the parsing process.
+
+Defining a Node
+~~~~~~~~~~~~~~~
+
+The ``Project_Set_Node`` class itself is rather simple::
+
+    class Project_Set_Node extends Twig_Node
+    {
+        public function __construct($name, Twig_Node_Expression $value, $line, $tag = null)
+        {
+            parent::__construct(array('value' => $value), array('name' => $name), $line, $tag);
+        }
+
+        public function compile(Twig_Compiler $compiler)
+        {
+            $compiler
+                ->addDebugInfo($this)
+                ->write('$context[\''.$this->getAttribute('name').'\'] = ')
+                ->subcompile($this->getNode('value'))
+                ->raw(";\n")
+            ;
+        }
+    }
+
+The compiler implements a fluid interface and provides methods that helps the
+developer generate beautiful and readable PHP code:
+
+* ``subcompile()``: Compiles a node.
+
+* ``raw()``: Writes the given string as is.
+
+* ``write()``: Writes the given string by adding indentation at the beginning
+  of each line.
+
+* ``string()``: Writes a quoted string.
+
+* ``repr()``: Writes a PHP representation of a given value (see
+  ``Twig_Node_For`` for a usage example).
+
+* ``addDebugInfo()``: Adds the line of the original template file related to
+  the current node as a comment.
+
+* ``indent()``: Indents the generated code (see ``Twig_Node_Block`` for a
+  usage example).
+
+* ``outdent()``: Outdents the generated code (see ``Twig_Node_Block`` for a
+  usage example).
+
+.. _creating_extensions:
+
+Creating an Extension
+---------------------
+
+The main motivation for writing an extension is to move often used code into a
+reusable class like adding support for internationalization. An extension can
+define tags, filters, tests, operators, global variables, functions, and node
+visitors.
+
+Most of the time, it is useful to create a single extension for your project,
+to host all the specific tags and filters you want to add to Twig.
+
+.. tip::
+
+    When packaging your code into an extension, Twig is smart enough to
+    recompile your templates whenever you make a change to it (when
+    ``auto_reload`` is enabled).
+
+.. note::
+
+    Before writing your own extensions, have a look at the Twig official
+    extension repository: https://github.com/twigphp/Twig-extensions.
+
+An extension is a class that implements the following interface::
+
+    interface Twig_ExtensionInterface
+    {
+        /**
+         * Returns the token parser instances to add to the existing list.
+         *
+         * @return Twig_TokenParserInterface[]
+         */
+        public function getTokenParsers();
+
+        /**
+         * Returns the node visitor instances to add to the existing list.
+         *
+         * @return Twig_NodeVisitorInterface[]
+         */
+        public function getNodeVisitors();
+
+        /**
+         * Returns a list of filters to add to the existing list.
+         *
+         * @return Twig_Filter[]
+         */
+        public function getFilters();
+
+        /**
+         * Returns a list of tests to add to the existing list.
+         *
+         * @return Twig_Test[]
+         */
+        public function getTests();
+
+        /**
+         * Returns a list of functions to add to the existing list.
+         *
+         * @return Twig_Function[]
+         */
+        public function getFunctions();
+
+        /**
+         * Returns a list of operators to add to the existing list.
+         *
+         * @return array<array> First array of unary operators, second array of binary operators
+         */
+        public function getOperators();
+    }
+
+To keep your extension class clean and lean, inherit from the built-in
+``Twig_Extension`` class instead of implementing the interface as it provides
+empty implementations for all methods:
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+    }
+
+Of course, this extension does nothing for now. We will customize it in the
+next sections.
+
+Twig does not care where you save your extension on the filesystem, as all
+extensions must be registered explicitly to be available in your templates.
+
+You can register an extension by using the ``addExtension()`` method on your
+main ``Environment`` object::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addExtension(new Project_Twig_Extension());
+
+.. tip::
+
+    The Twig core extensions are great examples of how extensions work.
+
+Globals
+~~~~~~~
+
+Global variables can be registered in an extension via the ``getGlobals()``
+method::
+
+    class Project_Twig_Extension extends Twig_Extension implements Twig_Extension_GlobalsInterface
+    {
+        public function getGlobals()
+        {
+            return array(
+                'text' => new Text(),
+            );
+        }
+
+        // ...
+    }
+
+Functions
+~~~~~~~~~
+
+Functions can be registered in an extension via the ``getFunctions()``
+method::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getFunctions()
+        {
+            return array(
+                new Twig_Function('lipsum', 'generate_lipsum'),
+            );
+        }
+
+        // ...
+    }
+
+Filters
+~~~~~~~
+
+To add a filter to an extension, you need to override the ``getFilters()``
+method. This method must return an array of filters to add to the Twig
+environment::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getFilters()
+        {
+            return array(
+                new Twig_Filter('rot13', 'str_rot13'),
+            );
+        }
+
+        // ...
+    }
+
+Tags
+~~~~
+
+Adding a tag in an extension can be done by overriding the
+``getTokenParsers()`` method. This method must return an array of tags to add
+to the Twig environment::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getTokenParsers()
+        {
+            return array(new Project_Set_TokenParser());
+        }
+
+        // ...
+    }
+
+In the above code, we have added a single new tag, defined by the
+``Project_Set_TokenParser`` class. The ``Project_Set_TokenParser`` class is
+responsible for parsing the tag and compiling it to PHP.
+
+Operators
+~~~~~~~~~
+
+The ``getOperators()`` methods lets you add new operators. Here is how to add
+``!``, ``||``, and ``&&`` operators::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getOperators()
+        {
+            return array(
+                array(
+                    '!' => array('precedence' => 50, 'class' => 'Twig_Node_Expression_Unary_Not'),
+                ),
+                array(
+                    '||' => array('precedence' => 10, 'class' => 'Twig_Node_Expression_Binary_Or', 'associativity' => Twig_ExpressionParser::OPERATOR_LEFT),
+                    '&&' => array('precedence' => 15, 'class' => 'Twig_Node_Expression_Binary_And', 'associativity' => Twig_ExpressionParser::OPERATOR_LEFT),
+                ),
+            );
+        }
+
+        // ...
+    }
+
+Tests
+~~~~~
+
+The ``getTests()`` method lets you add new test functions::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getTests()
+        {
+            return array(
+                new Twig_Test('even', 'twig_test_even'),
+            );
+        }
+
+        // ...
+    }
+
+Definition vs Runtime
+~~~~~~~~~~~~~~~~~~~~~
+
+Twig filters, functions, and tests runtime implementations can be defined as
+any valid PHP callable:
+
+* **functions/static methods**: Simple to implement and fast (used by all Twig
+  core extensions); but it is hard for the runtime to depend on external
+  objects;
+
+* **closures**: Simple to implement;
+
+* **object methods**: More flexible and required if your runtime code depends
+  on external objects.
+
+The simplest way to use methods is to define them on the extension itself::
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        private $rot13Provider;
+
+        public function __construct($rot13Provider)
+        {
+            $this->rot13Provider = $rot13Provider;
+        }
+
+        public function getFunctions()
+        {
+            return array(
+                new Twig_Function('rot13', array($this, 'rot13')),
+            );
+        }
+
+        public function rot13($value)
+        {
+            return $this->rot13Provider->rot13($value);
+        }
+    }
+
+This is very convenient but not recommended as it makes template compilation
+depend on runtime dependencies even if they are not needed (think for instance
+as a dependency that connects to a database engine).
+
+You can easily decouple the extension definitions from their runtime
+implementations by registering a ``Twig_RuntimeLoaderInterface`` instance on
+the environment that knows how to instantiate such runtime classes (runtime
+classes must be autoload-able)::
+
+    class RuntimeLoader implements Twig_RuntimeLoaderInterface
+    {
+        public function load($class)
+        {
+            // implement the logic to create an instance of $class
+            // and inject its dependencies
+            // most of the time, it means using your dependency injection container
+            if ('Project_Twig_RuntimeExtension' === $class) {
+                return new $class(new Rot13Provider());
+            } else {
+                // ...
+            }
+        }
+    }
+
+    $twig->addRuntimeLoader(new RuntimeLoader());
+
+.. note::
+
+    Twig comes with a PSR-11 compatible runtime loader
+    (``Twig_ContainerRuntimeLoader``).
+
+It is now possible to move the runtime logic to a new
+``Project_Twig_RuntimeExtension`` class and use it directly in the extension::
+
+    class Project_Twig_RuntimeExtension
+    {
+        private $rot13Provider;
+
+        public function __construct($rot13Provider)
+        {
+            $this->rot13Provider = $rot13Provider;
+        }
+
+        public function rot13($value)
+        {
+            return $this->rot13Provider->rot13($value);
+        }
+    }
+
+    class Project_Twig_Extension extends Twig_Extension
+    {
+        public function getFunctions()
+        {
+            return array(
+                new Twig_Function('rot13', array('Project_Twig_RuntimeExtension', 'rot13')),
+                // or
+                new Twig_Function('rot13', 'Project_Twig_RuntimeExtension::rot13'),
+            );
+        }
+    }
+
+Overloading
+-----------
+
+To overload an already defined filter, test, operator, global variable, or
+function, re-define it in an extension and register it **as late as
+possible** (order matters)::
+
+    class MyCoreExtension extends Twig_Extension
+    {
+        public function getFilters()
+        {
+            return array(
+                new Twig_Filter('date', array($this, 'dateFilter')),
+            );
+        }
+
+        public function dateFilter($timestamp, $format = 'F j, Y H:i')
+        {
+            // do something different from the built-in date filter
+        }
+    }
+
+    $twig = new Twig_Environment($loader);
+    $twig->addExtension(new MyCoreExtension());
+
+Here, we have overloaded the built-in ``date`` filter with a custom one.
+
+If you do the same on the ``Twig_Environment`` itself, beware that it takes
+precedence over any other registered extensions::
+
+    $twig = new Twig_Environment($loader);
+    $twig->addFilter(new Twig_Filter('date', function ($timestamp, $format = 'F j, Y H:i') {
+        // do something different from the built-in date filter
+    }));
+    // the date filter will come from the above registration, not
+    // from the registered extension below
+    $twig->addExtension(new MyCoreExtension());
+
+.. caution::
+
+    Note that overloading the built-in Twig elements is not recommended as it
+    might be confusing.
+
+Testing an Extension
+--------------------
+
+Functional Tests
+~~~~~~~~~~~~~~~~
+
+You can create functional tests for extensions simply by creating the
+following file structure in your test directory::
+
+    Fixtures/
+        filters/
+            foo.test
+            bar.test
+        functions/
+            foo.test
+            bar.test
+        tags/
+            foo.test
+            bar.test
+    IntegrationTest.php
+
+The ``IntegrationTest.php`` file should look like this::
+
+    class Project_Tests_IntegrationTest extends Twig_Test_IntegrationTestCase
+    {
+        public function getExtensions()
+        {
+            return array(
+                new Project_Twig_Extension1(),
+                new Project_Twig_Extension2(),
+            );
+        }
+
+        public function getFixturesDir()
+        {
+            return dirname(__FILE__).'/Fixtures/';
+        }
+    }
+
+Fixtures examples can be found within the Twig repository
+`tests/Twig/Fixtures`_ directory.
+
+Node Tests
+~~~~~~~~~~
+
+Testing the node visitors can be complex, so extend your test cases from
+``Twig_Test_NodeTestCase``. Examples can be found in the Twig repository
+`tests/Twig/Node`_ directory.

+Twig for Developers
+===================
+
+This chapter describes the API to Twig and not the template language. It will
+be most useful as reference to those implementing the template interface to
+the application and not those who are creating Twig templates.
+
+Basics
+------
+
+Twig uses a central object called the **environment** (of class
+``Twig_Environment``). Instances of this class are used to store the
+configuration and extensions, and are used to load templates from the file
+system or other locations.
+
+Most applications will create one ``Twig_Environment`` object on application
+initialization and use that to load templates. In some cases it's however
+useful to have multiple environments side by side, if different configurations
+are in use.
+
+The simplest way to configure Twig to load templates for your application
+looks roughly like this::
+
+    require_once '/path/to/vendor/autoload.php';
+
+    $loader = new Twig_Loader_Filesystem('/path/to/templates');
+    $twig = new Twig_Environment($loader, array(
+        'cache' => '/path/to/compilation_cache',
+    ));
+
+This will create a template environment with the default settings and a loader
+that looks up the templates in the ``/path/to/templates/`` folder. Different
+loaders are available and you can also write your own if you want to load
+templates from a database or other resources.
+
+.. note::
+
+    Notice that the second argument of the environment is an array of options.
+    The ``cache`` option is a compilation cache directory, where Twig caches
+    the compiled templates to avoid the parsing phase for sub-sequent
+    requests. It is very different from the cache you might want to add for
+    the evaluated templates. For such a need, you can use any available PHP
+    cache library.
+
+Rendering Templates
+-------------------
+
+To load a template from a Twig environment, call the ``load()`` method which
+returns a ``Twig_TemplateWrapper`` instance::
+
+    $template = $twig->load('index.html');
+
+To render the template with some variables, call the ``render()`` method::
+
+    echo $template->render(array('the' => 'variables', 'go' => 'here'));
+
+.. note::
+
+    The ``display()`` method is a shortcut to output the template directly.
+
+You can also load and render the template in one fell swoop::
+
+    echo $twig->render('index.html', array('the' => 'variables', 'go' => 'here'));
+
+If a template defines blocks, they can be rendered individually via the
+``renderBlock()`` call::
+
+    echo $template->renderBlock('block_name', array('the' => 'variables', 'go' => 'here'));
+
+.. _environment_options:
+
+Environment Options
+-------------------
+
+When creating a new ``Twig_Environment`` instance, you can pass an array of
+options as the constructor second argument::
+
+    $twig = new Twig_Environment($loader, array('debug' => true));
+
+The following options are available:
+
+* ``debug`` *boolean*
+
+  When set to ``true``, the generated templates have a
+  ``__toString()`` method that you can use to display the generated nodes
+  (default to ``false``).
+
+* ``charset`` *string* (defaults to ``utf-8``)
+
+  The charset used by the templates.
+
+* ``base_template_class`` *string* (defaults to ``Twig_Template``)
+
+  The base template class to use for generated
+  templates.
+
+* ``cache`` *string* or ``false``
+
+  An absolute path where to store the compiled templates, or
+  ``false`` to disable caching (which is the default).
+
+* ``auto_reload`` *boolean*
+
+  When developing with Twig, it's useful to recompile the
+  template whenever the source code changes. If you don't provide a value for
+  the ``auto_reload`` option, it will be determined automatically based on the
+  ``debug`` value.
+
+* ``strict_variables`` *boolean*
+
+  If set to ``false``, Twig will silently ignore invalid
+  variables (variables and or attributes/methods that do not exist) and
+  replace them with a ``null`` value. When set to ``true``, Twig throws an
+  exception instead (default to ``false``).
+
+* ``autoescape`` *string*
+
+  Sets the default auto-escaping strategy (``name``, ``html``, ``js``, ``css``,
+  ``url``, ``html_attr``, or a PHP callback that takes the template "filename"
+  and returns the escaping strategy to use -- the callback cannot be a function
+  name to avoid collision with built-in escaping strategies); set it to
+  ``false`` to disable auto-escaping. The ``name`` escaping strategy determines
+  the escaping strategy to use for a template based on the template filename
+  extension (this strategy does not incur any overhead at runtime as
+  auto-escaping is done at compilation time.)
+
+* ``optimizations`` *integer*
+
+  A flag that indicates which optimizations to apply
+  (default to ``-1`` -- all optimizations are enabled; set it to ``0`` to
+  disable).
+
+Loaders
+-------
+
+Loaders are responsible for loading templates from a resource such as the file
+system.
+
+Compilation Cache
+~~~~~~~~~~~~~~~~~
+
+All template loaders can cache the compiled templates on the filesystem for
+future reuse. It speeds up Twig a lot as templates are only compiled once; and
+the performance boost is even larger if you use a PHP accelerator such as APC.
+See the ``cache`` and ``auto_reload`` options of ``Twig_Environment`` above
+for more information.
+
+Built-in Loaders
+~~~~~~~~~~~~~~~~
+
+Here is a list of the built-in loaders Twig provides:
+
+``Twig_Loader_Filesystem``
+..........................
+
+``Twig_Loader_Filesystem`` loads templates from the file system. This loader
+can find templates in folders on the file system and is the preferred way to
+load them::
+
+    $loader = new Twig_Loader_Filesystem($templateDir);
+
+It can also look for templates in an array of directories::
+
+    $loader = new Twig_Loader_Filesystem(array($templateDir1, $templateDir2));
+
+With such a configuration, Twig will first look for templates in
+``$templateDir1`` and if they do not exist, it will fallback to look for them
+in the ``$templateDir2``.
+
+You can add or prepend paths via the ``addPath()`` and ``prependPath()``
+methods::
+
+    $loader->addPath($templateDir3);
+    $loader->prependPath($templateDir4);
+
+The filesystem loader also supports namespaced templates. This allows to group
+your templates under different namespaces which have their own template paths.
+
+When using the ``setPaths()``, ``addPath()``, and ``prependPath()`` methods,
+specify the namespace as the second argument (when not specified, these
+methods act on the "main" namespace)::
+
+    $loader->addPath($templateDir, 'admin');
+
+Namespaced templates can be accessed via the special
+``@namespace_name/template_path`` notation::
+
+    $twig->render('@admin/index.html', array());
+
+``Twig_Loader_Filesystem`` support absolute and relative paths. Using relative
+paths is preferred as it makes the cache keys independent of the project root
+directory (for instance, it allows warming the cache from a build server where
+the directory might be different from the one used on production servers)::
+
+    $loader = new Twig_Loader_Filesystem('templates', getcwd().'/..');
+
+.. note::
+
+    When not passing the root path as a second argument, Twig uses ``getcwd()``
+    for relative paths.
+
+``Twig_Loader_Array``
+.....................
+
+``Twig_Loader_Array`` loads a template from a PHP array. It's passed an array
+of strings bound to template names::
+
+    $loader = new Twig_Loader_Array(array(
+        'index.html' => 'Hello {{ name }}!',
+    ));
+    $twig = new Twig_Environment($loader);
+
+    echo $twig->render('index.html', array('name' => 'Fabien'));
+
+This loader is very useful for unit testing. It can also be used for small
+projects where storing all templates in a single PHP file might make sense.
+
+.. tip::
+
+    When using the ``Array`` loader with a cache mechanism, you
+    should know that a new cache key is generated each time a template content
+    "changes" (the cache key being the source code of the template). If you
+    don't want to see your cache grows out of control, you need to take care
+    of clearing the old cache file by yourself.
+
+``Twig_Loader_Chain``
+.....................
+
+``Twig_Loader_Chain`` delegates the loading of templates to other loaders::
+
+    $loader1 = new Twig_Loader_Array(array(
+        'base.html' => '{% block content %}{% endblock %}',
+    ));
+    $loader2 = new Twig_Loader_Array(array(
+        'index.html' => '{% extends "base.html" %}{% block content %}Hello {{ name }}{% endblock %}',
+        'base.html'  => 'Will never be loaded',
+    ));
+
+    $loader = new Twig_Loader_Chain(array($loader1, $loader2));
+
+    $twig = new Twig_Environment($loader);
+
+When looking for a template, Twig will try each loader in turn and it will
+return as soon as the template is found. When rendering the ``index.html``
+template from the above example, Twig will load it with ``$loader2`` but the
+``base.html`` template will be loaded from ``$loader1``.
+
+``Twig_Loader_Chain`` accepts any loader that implements
+``Twig_LoaderInterface``.
+
+.. note::
+
+    You can also add loaders via the ``addLoader()`` method.
+
+Create your own Loader
+~~~~~~~~~~~~~~~~~~~~~~
+
+All loaders implement the ``Twig_LoaderInterface``::
+
+    interface Twig_LoaderInterface
+    {
+        /**
+         * Returns the source context for a given template logical name.
+         *
+         * @param string $name The template logical name
+         *
+         * @return Twig_Source
+         *
+         * @throws Twig_Error_Loader When $name is not found
+         */
+        public function getSourceContext($name);
+
+        /**
+         * Gets the cache key to use for the cache for a given template name.
+         *
+         * @param string $name The name of the template to load
+         *
+         * @return string The cache key
+         *
+         * @throws Twig_Error_Loader When $name is not found
+         */
+        public function getCacheKey($name);
+
+        /**
+         * Returns true if the template is still fresh.
+         *
+         * @param string    $name The template name
+         * @param timestamp $time The last modification time of the cached template
+         *
+         * @return bool    true if the template is fresh, false otherwise
+         *
+         * @throws Twig_Error_Loader When $name is not found
+         */
+        public function isFresh($name, $time);
+
+        /**
+         * Check if we have the source code of a template, given its name.
+         *

+         *
+         * @return bool    If the template source code is handled by this loader or not
+         */
+        public function exists($name);
+    }
+
+The ``isFresh()`` method must return ``true`` if the current cached template
+is still fresh, given the last modification time, or ``false`` otherwise.
+
+The ``getSourceContext()`` method must return an instance of ``Twig_Source``.
+
+Using Extensions
+----------------
+
+Twig extensions are packages that add new features to Twig. Using an
+extension is as simple as using the ``addExtension()`` method::
+
+    $twig->addExtension(new Twig_Extension_Sandbox());
+
+Twig comes bundled with the following extensions:
+
+* *Twig_Extension_Core*: Defines all the core features of Twig.
+
+* *Twig_Extension_Escaper*: Adds automatic output-escaping and the possibility
+  to escape/unescape blocks of code.
+
+* *Twig_Extension_Sandbox*: Adds a sandbox mode to the default Twig
+  environment, making it safe to evaluate untrusted code.
+
+* *Twig_Extension_Profiler*: Enabled the built-in Twig profiler.
+
+* *Twig_Extension_Optimizer*: Optimizes the node tree before compilation.
+
+The core, escaper, and optimizer extensions do not need to be added to the
+Twig environment, as they are registered by default.
+
+Built-in Extensions
+-------------------
+
+This section describes the features added by the built-in extensions.
+
+.. tip::
+
+    Read the chapter about extending Twig to learn how to create your own
+    extensions.
+
+Core Extension
+~~~~~~~~~~~~~~
+
+The ``core`` extension defines all the core features of Twig:
+
+* :doc:`Tags <tags/index>`;
+* :doc:`Filters <filters/index>`;
+* :doc:`Functions <functions/index>`;
+* :doc:`Tests <tests/index>`.
+
+Escaper Extension
+~~~~~~~~~~~~~~~~~
+
+The ``escaper`` extension adds automatic output escaping to Twig. It defines a
+tag, ``autoescape``, and a filter, ``raw``.
+
+When creating the escaper extension, you can switch on or off the global
+output escaping strategy::
+
+    $escaper = new Twig_Extension_Escaper('html');
+    $twig->addExtension($escaper);
+
+If set to ``html``, all variables in templates are escaped (using the ``html``
+escaping strategy), except those using the ``raw`` filter:
+
+.. code-block:: jinja
+
+    {{ article.to_html|raw }}
+
+You can also change the escaping mode locally by using the ``autoescape`` tag:
+
+.. code-block:: jinja
+
+    {% autoescape 'html' %}
+        {{ var }}
+        {{ var|raw }}      {# var won't be escaped #}
+        {{ var|escape }}   {# var won't be double-escaped #}
+    {% endautoescape %}
+
+.. warning::
+
+    The ``autoescape`` tag has no effect on included files.
+
+The escaping rules are implemented as follows:
+
+* Literals (integers, booleans, arrays, ...) used in the template directly as
+  variables or filter arguments are never automatically escaped:
+
+  .. code-block:: jinja
+
+        {{ "Twig<br />" }} {# won't be escaped #}
+
+        {% set text = "Twig<br />" %}
+        {{ text }} {# will be escaped #}
+
+* Expressions which the result is always a literal or a variable marked safe
+  are never automatically escaped:
+
+  .. code-block:: jinja
+
+        {{ foo ? "Twig<br />" : "<br />Twig" }} {# won't be escaped #}
+
+        {% set text = "Twig<br />" %}
+        {{ foo ? text : "<br />Twig" }} {# will be escaped #}
+
+        {% set text = "Twig<br />" %}
+        {{ foo ? text|raw : "<br />Twig" }} {# won't be escaped #}
+
+        {% set text = "Twig<br />" %}
+        {{ foo ? text|escape : "<br />Twig" }} {# the result of the expression won't be escaped #}
+
+* Escaping is applied before printing, after any other filter is applied:
+
+  .. code-block:: jinja
+
+        {{ var|upper }} {# is equivalent to {{ var|upper|escape }} #}
+
+* The `raw` filter should only be used at the end of the filter chain:
+
+  .. code-block:: jinja
+
+        {{ var|raw|upper }} {# will be escaped #}
+
+        {{ var|upper|raw }} {# won't be escaped #}
+
+* Automatic escaping is not applied if the last filter in the chain is marked
+  safe for the current context (e.g. ``html`` or ``js``). ``escape`` and
+  ``escape('html')`` are marked safe for HTML, ``escape('js')`` is marked
+  safe for JavaScript, ``raw`` is marked safe for everything.
+
+  .. code-block:: jinja
+
+        {% autoescape 'js' %}
+            {{ var|escape('html') }} {# will be escaped for HTML and JavaScript #}
+            {{ var }} {# will be escaped for JavaScript #}
+            {{ var|escape('js') }} {# won't be double-escaped #}
+        {% endautoescape %}
+
+.. note::
+
+    Note that autoescaping has some limitations as escaping is applied on
+    expressions after evaluation. For instance, when working with
+    concatenation, ``{{ foo|raw ~ bar }}`` won't give the expected result as
+    escaping is applied on the result of the concatenation, not on the
+    individual variables (so, the ``raw`` filter won't have any effect here).
+
+Sandbox Extension
+~~~~~~~~~~~~~~~~~
+
+The ``sandbox`` extension can be used to evaluate untrusted code. Access to
+unsafe attributes and methods is prohibited. The sandbox security is managed
+by a policy instance. By default, Twig comes with one policy class:
+``Twig_Sandbox_SecurityPolicy``. This class allows you to white-list some
+tags, filters, properties, and methods::
+
+    $tags = array('if');
+    $filters = array('upper');
+    $methods = array(
+        'Article' => array('getTitle', 'getBody'),
+    );
+    $properties = array(
+        'Article' => array('title', 'body'),
+    );
+    $functions = array('range');
+    $policy = new Twig_Sandbox_SecurityPolicy($tags, $filters, $methods, $properties, $functions);
+
+With the previous configuration, the security policy will only allow usage of
+the ``if`` tag, and the ``upper`` filter. Moreover, the templates will only be
+able to call the ``getTitle()`` and ``getBody()`` methods on ``Article``
+objects, and the ``title`` and ``body`` public properties. Everything else
+won't be allowed and will generate a ``Twig_Sandbox_SecurityError`` exception.
+
+The policy object is the first argument of the sandbox constructor::
+
+    $sandbox = new Twig_Extension_Sandbox($policy);
+    $twig->addExtension($sandbox);
+
+By default, the sandbox mode is disabled and should be enabled when including
+untrusted template code by using the ``sandbox`` tag:
+
+.. code-block:: jinja
+
+    {% sandbox %}
+        {% include 'user.html' %}
+    {% endsandbox %}
+
+You can sandbox all templates by passing ``true`` as the second argument of
+the extension constructor::
+
+    $sandbox = new Twig_Extension_Sandbox($policy, true);
+
+Profiler Extension
+~~~~~~~~~~~~~~~~~~
+
+The ``profiler`` extension enables a profiler for Twig templates; it should
+only be used on your development machines as it adds some overhead::
+
+    $profile = new Twig_Profiler_Profile();
+    $twig->addExtension(new Twig_Extension_Profiler($profile));
+
+    $dumper = new Twig_Profiler_Dumper_Text();
+    echo $dumper->dump($profile);
+
+A profile contains information about time and memory consumption for template,
+block, and macro executions.
+
+You can also dump the data in a `Blackfire.io <https://blackfire.io/>`_
+compatible format::
+
+    $dumper = new Twig_Profiler_Dumper_Blackfire();
+    file_put_contents('/path/to/profile.prof', $dumper->dump($profile));
+
+Upload the profile to visualize it (create a `free account
+<https://blackfire.io/signup>`_ first):
+
+.. code-block:: sh
+
+    blackfire --slot=7 upload /path/to/profile.prof
+
+Optimizer Extension
+~~~~~~~~~~~~~~~~~~~
+
+The ``optimizer`` extension optimizes the node tree before compilation::
+
+    $twig->addExtension(new Twig_Extension_Optimizer());
+
+By default, all optimizations are turned on. You can select the ones you want
+to enable by passing them to the constructor::
+
+    $optimizer = new Twig_Extension_Optimizer(Twig_NodeVisitor_Optimizer::OPTIMIZE_FOR);
+
+    $twig->addExtension($optimizer);
+
+Twig supports the following optimizations:
+
+* ``Twig_NodeVisitor_Optimizer::OPTIMIZE_ALL``, enables all optimizations
+  (this is the default value).
+* ``Twig_NodeVisitor_Optimizer::OPTIMIZE_NONE``, disables all optimizations.
+  This reduces the compilation time, but it can increase the execution time
+  and the consumed memory.
+* ``Twig_NodeVisitor_Optimizer::OPTIMIZE_FOR``, optimizes the ``for`` tag by
+  removing the ``loop`` variable creation whenever possible.
+* ``Twig_NodeVisitor_Optimizer::OPTIMIZE_RAW_FILTER``, removes the ``raw``
+  filter whenever possible.
+* ``Twig_NodeVisitor_Optimizer::OPTIMIZE_VAR_ACCESS``, simplifies the creation
+  and access of variables in the compiled templates whenever possible.
+
+Exceptions
+----------
+
+Twig can throw exceptions:
+
+* ``Twig_Error``: The base exception for all errors.
+
+* ``Twig_Error_Syntax``: Thrown to tell the user that there is a problem with
+  the template syntax.
+
+* ``Twig_Error_Runtime``: Thrown when an error occurs at runtime (when a filter
+  does not exist for instance).
+
+* ``Twig_Error_Loader``: Thrown when an error occurs during template loading.
+
+* ``Twig_Sandbox_SecurityError``: Thrown when an unallowed tag, filter, or
+  method is called in a sandboxed template.

+Coding Standards
+================
+
+When writing Twig templates, we recommend you to follow these official coding
+standards:
+
+* Put one (and only one) space after the start of a delimiter (``{{``, ``{%``,
+  and ``{#``) and before the end of a delimiter (``}}``, ``%}``, and ``#}``):
+
+  .. code-block:: jinja
+
+    {{ foo }}
+    {# comment #}
+    {% if foo %}{% endif %}
+
+  When using the whitespace control character, do not put any spaces between
+  it and the delimiter:
+
+  .. code-block:: jinja
+
+    {{- foo -}}
+    {#- comment -#}
+    {%- if foo -%}{%- endif -%}
+
+* Put one (and only one) space before and after the following operators:
+  comparison operators (``==``, ``!=``, ``<``, ``>``, ``>=``, ``<=``), math
+  operators (``+``, ``-``, ``/``, ``*``, ``%``, ``//``, ``**``), logic
+  operators (``not``, ``and``, ``or``), ``~``, ``is``, ``in``, and the ternary
+  operator (``?:``):
+
+  .. code-block:: jinja
+
+     {{ 1 + 2 }}
+     {{ foo ~ bar }}
+     {{ true ? true : false }}
+
+* Put one (and only one) space after the ``:`` sign in hashes and ``,`` in
+  arrays and hashes:
+
+  .. code-block:: jinja
+
+     {{ [1, 2, 3] }}
+     {{ {'foo': 'bar'} }}
+
+* Do not put any spaces after an opening parenthesis and before a closing
+  parenthesis in expressions:
+
+  .. code-block:: jinja
+
+    {{ 1 + (2 * 3) }}
+
+* Do not put any spaces before and after string delimiters:
+
+  .. code-block:: jinja
+
+    {{ 'foo' }}
+    {{ "foo" }}
+
+* Do not put any spaces before and after the following operators: ``|``,
+  ``.``, ``..``, ``[]``:
+
+  .. code-block:: jinja
+
+    {{ foo|upper|lower }}
+    {{ user.name }}
+    {{ user[name] }}
+    {% for i in 1..12 %}{% endfor %}
+
+* Do not put any spaces before and after the parenthesis used for filter and
+  function calls:
+
+  .. code-block:: jinja
+
+     {{ foo|default('foo') }}
+     {{ range(1..10) }}
+
+* Do not put any spaces before and after the opening and the closing of arrays
+  and hashes:
+
+  .. code-block:: jinja
+
+     {{ [1, 2, 3] }}
+     {{ {'foo': 'bar'} }}
+
+* Use lower cased and underscored variable names:
+
+  .. code-block:: jinja
+
+     {% set foo = 'foo' %}
+     {% set foo_bar = 'foo' %}
+
+* Indent your code inside tags (use the same indentation as the one used for
+  the target language of the rendered template):
+
+  .. code-block:: jinja
+
+     {% block foo %}
+         {% if true %}
+             true
+         {% endif %}
+     {% endblock %}

+Deprecated Features
+===================
+
+This document lists deprecated features in Twig 2.x. Deprecated features are
+kept for backward compatibility and removed in the next major release (a
+feature that was deprecated in Twig 2.x is removed in Twig 3.0).
+
+Inheritance
+-----------
+
+* Defining a "block" definition in a non-capturing block in a child template is
+  deprecated since Twig 2.5.0. In Twig 3.0, it will throw a
+  ``Twig_Error_Syntax`` exception. It does not work anyway, so most projects
+  won't need to do anything to upgrade.
+
+Tags
+----
+
+* Using the ``spaceless`` tag at the root level of a child template is
+  deprecated in Twig 2.5.0. This does not work as one would expect it to work
+  anyway. In Twig 3.0, it will throw a ``Twig_Error_Syntax`` exception.
+
+Final Classes
+-------------
+
+The following classes are marked as ``@final`` in Twig 2 and will be final in
+3.0:
+
+* ``Twig_Node_Module``
+* ``Twig_Filter``
+* ``Twig_Function``
+* ``Twig_Test``
+* ``Twig_Profiler_Profile``

+``date``
+========
+
+The ``date`` filter formats a date to a given format:
+
+.. code-block:: jinja
+
+    {{ post.published_at|date("m/d/Y") }}
+
+The format specifier is the same as supported by `date`_,
+except when the filtered data is of type `DateInterval`_, when the format must conform to
+`DateInterval::format`_ instead.
+
+The ``date`` filter accepts strings (it must be in a format supported by the
+`strtotime`_ function), `DateTime`_ instances, or `DateInterval`_ instances. For
+instance, to display the current date, filter the word "now":
+
+.. code-block:: jinja
+
+    {{ "now"|date("m/d/Y") }}
+
+To escape words and characters in the date format use ``\\`` in front of each
+character:
+
+.. code-block:: jinja
+
+    {{ post.published_at|date("F jS \\a\\t g:ia") }}
+
+If the value passed to the ``date`` filter is ``null``, it will return the
+current date by default. If an empty string is desired instead of the current
+date, use a ternary operator:
+
+.. code-block:: jinja
+
+    {{ post.published_at is empty ? "" : post.published_at|date("m/d/Y") }}
+
+If no format is provided, Twig will use the default one: ``F j, Y H:i``. This
+default can be easily changed by calling the ``setDateFormat()`` method on the
+``core`` extension instance. The first argument is the default format for
+dates and the second one is the default format for date intervals:
+
+.. code-block:: php
+
+    $twig = new Twig_Environment($loader);
+    $twig->getExtension('Twig_Extension_Core')->setDateFormat('d/m/Y', '%d days');
+
+Timezone
+--------
+
+By default, the date is displayed by applying the default timezone (the one
+specified in php.ini or declared in Twig -- see below), but you can override
+it by explicitly specifying a timezone:
+
+.. code-block:: jinja
+
+    {{ post.published_at|date("m/d/Y", "Europe/Paris") }}
+
+If the date is already a DateTime object, and if you want to keep its current
+timezone, pass ``false`` as the timezone value:
+
+.. code-block:: jinja
+
+    {{ post.published_at|date("m/d/Y", false) }}
+
+The default timezone can also be set globally by calling ``setTimezone()``:
+
+.. code-block:: php
+
+    $twig = new Twig_Environment($loader);
+    $twig->getExtension('Twig_Extension_Core')->setTimezone('Europe/Paris');
+

+The ``escape`` filter escapes a string for safe insertion into the final
+output. It supports different escaping strategies depending on the template
+context.
+
+By default, it uses the HTML escaping strategy:
+
+.. code-block:: jinja
+
+    {{ user.username|escape }}
+
+For convenience, the ``e`` filter is defined as an alias:
+
+.. code-block:: jinja
+
+    {{ user.username|e }}
+
+The ``escape`` filter can also be used in other contexts than HTML thanks to
+an optional argument which defines the escaping strategy to use:
+
+.. code-block:: jinja
+
+    {{ user.username|e }}
+    {# is equivalent to #}
+    {{ user.username|e('html') }}
+
+And here is how to escape variables included in JavaScript code:
+
+.. code-block:: jinja
+
+    {{ user.username|escape('js') }}
+    {{ user.username|e('js') }}
+
+The ``escape`` filter supports the following escaping strategies:
+
+* ``html``: escapes a string for the **HTML body** context.
+
+* ``js``: escapes a string for the **JavaScript context**.
+
+* ``css``: escapes a string for the **CSS context**. CSS escaping can be
+  applied to any string being inserted into CSS and escapes everything except
+  alphanumerics.
+
+* ``url``: escapes a string for the **URI or parameter contexts**. This should
+  not be used to escape an entire URI; only a subcomponent being inserted.
+
+* ``html_attr``: escapes a string for the **HTML attribute** context.
+
+.. note::
+
+    Internally, ``escape`` uses the PHP native `htmlspecialchars`_ function
+    for the HTML escaping strategy.
+
+.. caution::
+
+    When using automatic escaping, Twig tries to not double-escape a variable
+    when the automatic escaping strategy is the same as the one applied by the
+    escape filter; but that does not work when using a variable as the
+    escaping strategy:
+
+    .. code-block:: jinja
+
+        {% set strategy = 'html' %}
+
+        {% autoescape 'html' %}
+            {{ var|escape('html') }}   {# won't be double-escaped #}
+            {{ var|escape(strategy) }} {# will be double-escaped #}
+        {% endautoescape %}
+
+    When using a variable as the escaping strategy, you should disable
+    automatic escaping:
+
+    .. code-block:: jinja
+
+        {% set strategy = 'html' %}
+
+        {% autoescape 'html' %}
+            {{ var|escape(strategy)|raw }} {# won't be double-escaped #}
+        {% endautoescape %}
+
+Custom Escapers
+---------------
+
+You can define custom escapers by calling the ``setEscaper()`` method on the
+``core`` extension instance. The first argument is the escaper name (to be
+used in the ``escape`` call) and the second one must be a valid PHP callable:
+
+.. code-block:: php
+
+    $twig = new Twig_Environment($loader);
+    $twig->getExtension('Twig_Extension_Core')->setEscaper('csv', 'csv_escaper');
+
+When called by Twig, the callable receives the Twig environment instance, the
+string to escape, and the charset.
+
+.. note::
+
+    Built-in escapers cannot be overridden mainly they should be considered as
+    the final implementation and also for better performance.
+
+Arguments
+---------
+
+* ``strategy``: The escaping strategy
+* ``charset``:  The string charset

+``number_format``
+=================
+
+The ``number_format`` filter formats numbers.  It is a wrapper around PHP's
+`number_format`_ function:
+
+.. code-block:: jinja
+
+    {{ 200.35|number_format }}
+
+You can control the number of decimal places, decimal point, and thousands
+separator using the additional arguments:
+
+.. code-block:: jinja
+
+    {{ 9800.333|number_format(2, '.', ',') }}
+
+To format negative numbers, wrap the number with parentheses (needed because of
+Twig's :ref:`precedence of operators <twig-expressions>`:
+
+.. code-block:: jinja
+
+    {{ -9800.333|number_format(2, '.', ',') }} {# outputs : -9 #}
+    {{ (-9800.333)|number_format(2, '.', ',') }} {# outputs : -9,800.33 #}
+
+If no formatting options are provided then Twig will use the default formatting
+options of:
+
+* 0 decimal places.
+* ``.`` as the decimal point.
+* ``,`` as the thousands separator.
+
+These defaults can be easily changed through the core extension:
+
+.. code-block:: php
+
+    $twig = new Twig_Environment($loader);
+    $twig->getExtension('Twig_Extension_Core')->setNumberFormat(3, '.', ',');
+
+The defaults set for ``number_format`` can be over-ridden upon each call using the
+additional parameters.

+* ``decimal``:       The number of decimal points to display

+
+    {% for i in [1, 2, 3, 4, 5]|slice(start, length) %}
+        {# ... #}

+
+    {% for i in [1, 2, 3, 4, 5][start:length] %}
+        {# ... #}

+
+    {# you can omit the last argument -- which will select everything till the end #}
+    {{ '12345'[2:] }} {# will display "345" #}
+
+The ``slice`` filter works as the `array_slice`_ PHP function for arrays and
+`mb_substr`_ for strings with a fallback to `substr`_.
+
+If the start is non-negative, the sequence will start at that start in the
+variable. If start is negative, the sequence will start that far from the end
+of the variable.
+
+If length is given and is positive, then the sequence will have up to that

+``dump``
+========
+
+The ``dump`` function dumps information about a template variable. This is
+mostly useful to debug a template that does not behave as expected by
+introspecting its variables:
+
+.. code-block:: jinja
+
+    {{ dump(user) }}
+
+.. note::
+
+    The ``dump`` function is not available by default. You must add the
+    ``Twig_Extension_Debug`` extension explicitly when creating your Twig
+    environment::
+
+        $twig = new Twig_Environment($loader, array(
+            'debug' => true,
+            // ...
+        ));
+        $twig->addExtension(new Twig_Extension_Debug());
+
+    Even when enabled, the ``dump`` function won't display anything if the
+    ``debug`` option on the environment is not enabled (to avoid leaking debug
+    information on a production server).
+
+In an HTML context, wrap the output with a ``pre`` tag to make it easier to
+read:
+
+.. code-block:: jinja
+
+    <pre>
+        {{ dump(user) }}
+    </pre>
+
+.. tip::
+
+    Using a ``pre`` tag is not needed when `XDebug`_ is enabled and
+    ``html_errors`` is ``on``; as a bonus, the output is also nicer with
+    XDebug enabled.
+
+You can debug several variables by passing them as additional arguments:
+
+.. code-block:: jinja
+
+    {{ dump(user, categories) }}
+
+If you don't pass any value, all variables from the current context are

+``include``
+===========
+
+The ``include`` function returns the rendered content of a template:
+
+.. code-block:: jinja
+
+    {{ include('template.html') }}
+    {{ include(some_var) }}
+
+Included templates have access to the variables of the active context.
+
+If you are using the filesystem loader, the templates are looked for in the
+paths defined by it.
+
+The context is passed by default to the template but you can also pass
+additional variables:
+
+.. code-block:: jinja
+
+    {# template.html will have access to the variables from the current context and the additional ones provided #}
+    {{ include('template.html', {foo: 'bar'}) }}
+
+You can disable access to the context by setting ``with_context`` to
+``false``:
+
+.. code-block:: jinja
+
+    {# only the foo variable will be accessible #}
+    {{ include('template.html', {foo: 'bar'}, with_context = false) }}
+
+.. code-block:: jinja
+
+    {# no variables will be accessible #}
+    {{ include('template.html', with_context = false) }}
+
+And if the expression evaluates to a ``Twig_Template`` or a
+``Twig_TemplateWrapper`` instance, Twig will use it directly::
+
+    // {{ include(template) }}
+
+    $template = $twig->load('some_template.twig');
+
+    $twig->display('template.twig', array('template' => $template));
+
+When you set the ``ignore_missing`` flag, Twig will return an empty string if
+the template does not exist:
+
+.. code-block:: jinja
+
+    {{ include('sidebar.html', ignore_missing = true) }}
+
+You can also provide a list of templates that are checked for existence before
+inclusion. The first template that exists will be rendered:
+
+.. code-block:: jinja
+
+    {{ include(['page_detailed.html', 'page.html']) }}
+
+If ``ignore_missing`` is set, it will fall back to rendering nothing if none
+of the templates exist, otherwise it will throw an exception.
+
+When including a template created by an end user, you should consider
+sandboxing it:
+
+.. code-block:: jinja
+
+    {{ include('page.html', sandboxed = true) }}
+
+Arguments
+---------
+
+* ``template``:       The template to render
+* ``variables``:      The variables to pass to the template
+* ``with_context``:   Whether to pass the current context variables or not

+
+Returns a list containing an arithmetic progression of integers:
+
+.. code-block:: jinja
+
+    {% for i in range(0, 3) %}
+        {{ i }},
+    {% endfor %}
+
+    {# outputs 0, 1, 2, 3, #}
+
+When step is given (as the third parameter), it specifies the increment (or
+decrement for negative values):
+
+.. code-block:: jinja
+
+    {% for i in range(0, 6, 2) %}
+        {{ i }},
+    {% endfor %}
+
+    {# outputs 0, 2, 4, 6, #}
+
+.. note::
+
+    Note that if the start is greater than the end, ``range`` assumes a step of
+    ``-1``:
+
+    .. code-block:: jinja
+
+        {% for i in range(3, 0) %}
+            {{ i }},
+        {% endfor %}
+
+        {# outputs 3, 2, 1, 0, #}
+
+The Twig built-in ``..`` operator is just syntactic sugar for the ``range``
+function (with a step of ``1``, or ``-1`` if the start is greater than the end):
+
+.. code-block:: jinja
+
+    {% for i in 0..3 %}
+        {{ i }},
+    {% endfor %}
+
+.. tip::
+
+    The ``range`` function works as the native PHP `range`_ function.
+
+Arguments
+---------
+
+* ``low``:  The first value of the sequence.
+* ``high``: The highest possible value of the sequence.
+* ``step``: The increment between elements of the sequence.

+``source``
+==========
+
+The ``source`` function returns the content of a template without rendering it:
+
+.. code-block:: jinja
+
+    {{ source('template.html') }}
+    {{ source(some_var) }}
+

+
+    {{ source('template.html', ignore_missing = true) }}
+
+The function uses the same template loaders as the ones used to include

+Twig Internals
+==============
+
+Twig is very extensible and you can easily hack it. Keep in mind that you
+should probably try to create an extension before hacking the core, as most
+features and enhancements can be handled with extensions. This chapter is also
+useful for people who want to understand how Twig works under the hood.
+
+How does Twig work?
+-------------------
+
+The rendering of a Twig template can be summarized into four key steps:
+
+* **Load** the template: If the template is already compiled, load it and go
+  to the *evaluation* step, otherwise:
+
+  * First, the **lexer** tokenizes the template source code into small pieces
+    for easier processing;
+  * Then, the **parser** converts the token stream into a meaningful tree
+    of nodes (the Abstract Syntax Tree);
+  * Eventually, the *compiler* transforms the AST into PHP code.
+
+* **Evaluate** the template: It basically means calling the ``display()``
+  method of the compiled template and passing it the context.
+
+The Lexer
+---------
+
+The lexer tokenizes a template source code into a token stream (each token is
+an instance of ``Twig_Token``, and the stream is an instance of
+``Twig_TokenStream``). The default lexer recognizes 13 different token types:
+
+* ``Twig_Token::BLOCK_START_TYPE``, ``Twig_Token::BLOCK_END_TYPE``: Delimiters for blocks (``{% %}``)
+* ``Twig_Token::VAR_START_TYPE``, ``Twig_Token::VAR_END_TYPE``: Delimiters for variables (``{{ }}``)
+* ``Twig_Token::TEXT_TYPE``: A text outside an expression;
+* ``Twig_Token::NAME_TYPE``: A name in an expression;
+* ``Twig_Token::NUMBER_TYPE``: A number in an expression;
+* ``Twig_Token::STRING_TYPE``: A string in an expression;
+* ``Twig_Token::OPERATOR_TYPE``: An operator;
+* ``Twig_Token::PUNCTUATION_TYPE``: A punctuation sign;
+* ``Twig_Token::INTERPOLATION_START_TYPE``, ``Twig_Token::INTERPOLATION_END_TYPE``: Delimiters for string interpolation;
+* ``Twig_Token::EOF_TYPE``: Ends of template.
+
+You can manually convert a source code into a token stream by calling the
+``tokenize()`` method of an environment::
+
+    $stream = $twig->tokenize(new Twig_Source($source, $identifier));
+
+As the stream has a ``__toString()`` method, you can have a textual
+representation of it by echoing the object::
+
+    echo $stream."\n";
+
+Here is the output for the ``Hello {{ name }}`` template:
+
+.. code-block:: text
+
+    TEXT_TYPE(Hello )
+    VAR_START_TYPE()
+    NAME_TYPE(name)
+    VAR_END_TYPE()
+    EOF_TYPE()
+
+.. note::
+
+    The default lexer (``Twig_Lexer``) can be changed by calling
+    the ``setLexer()`` method::
+
+        $twig->setLexer($lexer);
+
+The Parser
+----------
+
+The parser converts the token stream into an AST (Abstract Syntax Tree), or a
+node tree (an instance of ``Twig_Node_Module``). The core extension defines
+the basic nodes like: ``for``, ``if``, ... and the expression nodes.
+
+You can manually convert a token stream into a node tree by calling the
+``parse()`` method of an environment::
+
+    $nodes = $twig->parse($stream);
+
+Echoing the node object gives you a nice representation of the tree::
+
+    echo $nodes."\n";
+
+Here is the output for the ``Hello {{ name }}`` template:
+
+.. code-block:: text
+
+    Twig_Node_Module(
+      Twig_Node_Text(Hello )
+      Twig_Node_Print(
+        Twig_Node_Expression_Name(name)
+      )
+    )
+
+.. note::
+
+    The default parser (``Twig_TokenParser``) can be changed by calling the
+    ``setParser()`` method::
+
+        $twig->setParser($parser);
+
+The Compiler
+------------
+
+The last step is done by the compiler. It takes a node tree as an input and
+generates PHP code usable for runtime execution of the template.
+
+You can manually compile a node tree to PHP code with the ``compile()`` method
+of an environment::
+
+    $php = $twig->compile($nodes);
+
+The generated template for a ``Hello {{ name }}`` template reads as follows
+(the actual output can differ depending on the version of Twig you are
+using)::
+
+    /* Hello {{ name }} */
+    class __TwigTemplate_1121b6f109fe93ebe8c6e22e3712bceb extends Twig_Template
+    {
+        protected function doDisplay(array $context, array $blocks = array())
+        {
+            // line 1
+            echo "Hello ";
+            echo twig_escape_filter($this->env, (isset($context["name"]) ? $context["name"] : null), "html", null, true);
+        }
+
+        // some more code
+    }
+
+.. note::
+
+    The default compiler (``Twig_Compiler``) can be changed by calling the
+    ``setCompiler()`` method::
+
+        $twig->setCompiler($compiler);

+Introduction
+============
+
+This is the documentation for Twig, the flexible, fast, and secure template
+engine for PHP.
+
+If you have any exposure to other text-based template languages, such as
+Smarty, Django, or Jinja, you should feel right at home with Twig. It's both
+designer and developer friendly by sticking to PHP's principles and adding
+functionality useful for templating environments.
+
+The key-features are...
+
+* *Fast*: Twig compiles templates down to plain optimized PHP code. The
+  overhead compared to regular PHP code was reduced to the very minimum.
+
+* *Secure*: Twig has a sandbox mode to evaluate untrusted template code. This
+  allows Twig to be used as a template language for applications where users
+  may modify the template design.
+
+* *Flexible*: Twig is powered by a flexible lexer and parser. This allows the
+  developer to define their own custom tags and filters, and to create their own DSL.
+
+Twig is used by many Open-Source projects like Symfony, Drupal8, eZPublish,
+phpBB, Piwik, OroCRM; and many frameworks have support for it as well like
+Slim, Yii, Laravel, Codeigniter and Kohana — just to name a few.
+
+Prerequisites
+-------------
+
+Twig needs at least **PHP 7.0.0** to run.
+
+Installation
+------------
+
+The recommended way to install Twig is via Composer:
+
+.. code-block:: bash
+
+    composer require "twig/twig:^2.0"
+
+.. note::
+
+    To learn more about the other installation methods, read the
+    :doc:`installation<installation>` chapter; it also explains how to install
+    the Twig C extension.
+
+Basic API Usage
+---------------
+
+This section gives you a brief introduction to the PHP API for Twig.
+
+.. code-block:: php
+
+    require_once '/path/to/vendor/autoload.php';
+
+    $loader = new Twig_Loader_Array(array(
+        'index' => 'Hello {{ name }}!',
+    ));
+    $twig = new Twig_Environment($loader);
+
+    echo $twig->render('index', array('name' => 'Fabien'));
+
+Twig uses a loader (``Twig_Loader_Array``) to locate templates, and an
+environment (``Twig_Environment``) to store the configuration.
+
+The ``render()`` method loads the template passed as a first argument and
+renders it with the variables passed as a second argument.
+
+As templates are generally stored on the filesystem, Twig also comes with a
+filesystem loader::
+
+    $loader = new Twig_Loader_Filesystem('/path/to/templates');
+    $twig = new Twig_Environment($loader, array(
+        'cache' => '/path/to/compilation_cache',
+    ));
+
+    echo $twig->render('index.html', array('name' => 'Fabien'));

+Recipes
+=======
+
+.. _deprecation-notices:
+
+Displaying Deprecation Notices
+------------------------------
+
+Deprecated features generate deprecation notices (via a call to the
+``trigger_error()`` PHP function). By default, they are silenced and never
+displayed nor logged.
+
+To easily remove all deprecated feature usages from your templates, write and
+run a script along the lines of the following::
+
+    require_once __DIR__.'/vendor/autoload.php';
+
+    $twig = create_your_twig_env();
+
+    $deprecations = new Twig_Util_DeprecationCollector($twig);
+
+    print_r($deprecations->collectDir(__DIR__.'/templates'));
+
+The ``collectDir()`` method compiles all templates found in a directory,
+catches deprecation notices, and return them.
+
+.. tip::
+
+    If your templates are not stored on the filesystem, use the ``collect()``
+    method instead. ``collect()`` takes a ``Traversable`` which must return
+    template names as keys and template contents as values (as done by
+    ``Twig_Util_TemplateDirIterator``).
+
+However, this code won't find all deprecations (like using deprecated some Twig
+classes). To catch all notices, register a custom error handler like the one
+below::
+
+    $deprecations = array();
+    set_error_handler(function ($type, $msg) use (&$deprecations) {
+        if (E_USER_DEPRECATED === $type) {
+            $deprecations[] = $msg;
+        }
+    });
+
+    // run your application
+
+    print_r($deprecations);
+
+Note that most deprecation notices are triggered during **compilation**, so
+they won't be generated when templates are already cached.
+
+.. tip::
+
+    If you want to manage the deprecation notices from your PHPUnit tests, have
+    a look at the `symfony/phpunit-bridge
+    <https://github.com/symfony/phpunit-bridge>`_ package, which eases the
+    process a lot.
+
+Making a Layout conditional
+---------------------------
+
+Working with Ajax means that the same content is sometimes displayed as is,
+and sometimes decorated with a layout. As Twig layout template names can be
+any valid expression, you can pass a variable that evaluates to ``true`` when
+the request is made via Ajax and choose the layout accordingly:
+
+.. code-block:: jinja
+
+    {% extends request.ajax ? "base_ajax.html" : "base.html" %}
+
+    {% block content %}
+        This is the content to be displayed.
+    {% endblock %}
+
+Making an Include dynamic
+-------------------------
+
+When including a template, its name does not need to be a string. For
+instance, the name can depend on the value of a variable:
+
+.. code-block:: jinja
+
+    {% include var ~ '_foo.html' %}
+
+If ``var`` evaluates to ``index``, the ``index_foo.html`` template will be
+rendered.
+
+As a matter of fact, the template name can be any valid expression, such as
+the following:
+
+.. code-block:: jinja
+
+    {% include var|default('index') ~ '_foo.html' %}
+
+Overriding a Template that also extends itself
+----------------------------------------------
+
+A template can be customized in two different ways:
+
+* *Inheritance*: A template *extends* a parent template and overrides some
+  blocks;
+
+* *Replacement*: If you use the filesystem loader, Twig loads the first
+  template it finds in a list of configured directories; a template found in a
+  directory *replaces* another one from a directory further in the list.
+
+But how do you combine both: *replace* a template that also extends itself
+(aka a template in a directory further in the list)?
+
+Let's say that your templates are loaded from both ``.../templates/mysite``
+and ``.../templates/default`` in this order. The ``page.twig`` template,
+stored in ``.../templates/default`` reads as follows:
+
+.. code-block:: jinja
+
+    {# page.twig #}
+    {% extends "layout.twig" %}
+
+    {% block content %}
+    {% endblock %}
+
+You can replace this template by putting a file with the same name in
+``.../templates/mysite``. And if you want to extend the original template, you
+might be tempted to write the following:
+
+.. code-block:: jinja
+
+    {# page.twig in .../templates/mysite #}
+    {% extends "page.twig" %} {# from .../templates/default #}
+
+Of course, this will not work as Twig will always load the template from
+``.../templates/mysite``.
+
+It turns out it is possible to get this to work, by adding a directory right
+at the end of your template directories, which is the parent of all of the
+other directories: ``.../templates`` in our case. This has the effect of
+making every template file within our system uniquely addressable. Most of the
+time you will use the "normal" paths, but in the special case of wanting to
+extend a template with an overriding version of itself we can reference its
+parent's full, unambiguous template path in the extends tag:
+
+.. code-block:: jinja
+
+    {# page.twig in .../templates/mysite #}
+    {% extends "default/page.twig" %} {# from .../templates #}
+
+.. note::
+
+    This recipe was inspired by the following Django wiki page:
+    https://code.djangoproject.com/wiki/ExtendingTemplates
+
+Customizing the Syntax
+----------------------
+
+Twig allows some syntax customization for the block delimiters. It's not
+recommended to use this feature as templates will be tied with your custom
+syntax. But for specific projects, it can make sense to change the defaults.
+
+To change the block delimiters, you need to create your own lexer object::
+
+    $twig = new Twig_Environment(...);
+
+    $lexer = new Twig_Lexer($twig, array(
+        'tag_comment'   => array('{#', '#}'),
+        'tag_block'     => array('{%', '%}'),
+        'tag_variable'  => array('{{', '}}'),
+        'interpolation' => array('#{', '}'),
+    ));
+    $twig->setLexer($lexer);
+
+Here are some configuration example that simulates some other template engines
+syntax::
+
+    // Ruby erb syntax
+    $lexer = new Twig_Lexer($twig, array(
+        'tag_comment'  => array('<%#', '%>'),
+        'tag_block'    => array('<%', '%>'),
+        'tag_variable' => array('<%=', '%>'),
+    ));
+
+    // SGML Comment Syntax
+    $lexer = new Twig_Lexer($twig, array(
+        'tag_comment'  => array('<!--#', '-->'),
+        'tag_block'    => array('<!--', '-->'),
+        'tag_variable' => array('${', '}'),
+    ));
+
+    // Smarty like
+    $lexer = new Twig_Lexer($twig, array(
+        'tag_comment'  => array('{*', '*}'),
+        'tag_block'    => array('{', '}'),
+        'tag_variable' => array('{$', '}'),
+    ));
+
+Using dynamic Object Properties
+-------------------------------
+
+When Twig encounters a variable like ``article.title``, it tries to find a
+``title`` public property in the ``article`` object.
+
+It also works if the property does not exist but is rather defined dynamically
+thanks to the magic ``__get()`` method; you just need to also implement the
+``__isset()`` magic method like shown in the following snippet of code::
+
+    class Article
+    {
+        public function __get($name)
+        {
+            if ('title' == $name) {
+                return 'The title';
+            }
+
+            // throw some kind of error
+        }
+
+        public function __isset($name)
+        {
+            if ('title' == $name) {
+                return true;
+            }
+
+            return false;
+        }
+    }
+
+Accessing the parent Context in Nested Loops
+--------------------------------------------
+
+Sometimes, when using nested loops, you need to access the parent context. The
+parent context is always accessible via the ``loop.parent`` variable. For
+instance, if you have the following template data::
+
+    $data = array(
+        'topics' => array(
+            'topic1' => array('Message 1 of topic 1', 'Message 2 of topic 1'),
+            'topic2' => array('Message 1 of topic 2', 'Message 2 of topic 2'),
+        ),
+    );
+
+And the following template to display all messages in all topics:
+
+.. code-block:: jinja
+
+    {% for topic, messages in topics %}
+        * {{ loop.index }}: {{ topic }}
+      {% for message in messages %}
+          - {{ loop.parent.loop.index }}.{{ loop.index }}: {{ message }}
+      {% endfor %}
+    {% endfor %}
+
+The output will be similar to:
+
+.. code-block:: text
+
+    * 1: topic1
+      - 1.1: The message 1 of topic 1
+      - 1.2: The message 2 of topic 1
+    * 2: topic2
+      - 2.1: The message 1 of topic 2
+      - 2.2: The message 2 of topic 2
+
+In the inner loop, the ``loop.parent`` variable is used to access the outer
+context. So, the index of the current ``topic`` defined in the outer for loop
+is accessible via the ``loop.parent.loop.index`` variable.
+
+Defining undefined Functions and Filters on the Fly
+---------------------------------------------------
+
+When a function (or a filter) is not defined, Twig defaults to throw a
+``Twig_Error_Syntax`` exception. However, it can also call a `callback`_ (any
+valid PHP callable) which should return a function (or a filter).
+
+For filters, register callbacks with ``registerUndefinedFilterCallback()``.
+For functions, use ``registerUndefinedFunctionCallback()``::
+
+    // auto-register all native PHP functions as Twig functions
+    // don't try this at home as it's not secure at all!
+    $twig->registerUndefinedFunctionCallback(function ($name) {
+        if (function_exists($name)) {
+            return new Twig_Function($name, $name);
+        }
+
+        return false;
+    });
+
+If the callable is not able to return a valid function (or filter), it must
+return ``false``.
+
+If you register more than one callback, Twig will call them in turn until one
+does not return ``false``.
+
+.. tip::
+
+    As the resolution of functions and filters is done during compilation,
+    there is no overhead when registering these callbacks.
+
+Validating the Template Syntax
+------------------------------
+
+When template code is provided by a third-party (through a web interface for
+instance), it might be interesting to validate the template syntax before
+saving it. If the template code is stored in a `$template` variable, here is
+how you can do it::
+
+    try {
+        $twig->parse($twig->tokenize(new Twig_Source($template)));
+
+        // the $template is valid
+    } catch (Twig_Error_Syntax $e) {
+        // $template contains one or more syntax errors
+    }
+
+If you iterate over a set of files, you can pass the filename to the
+``tokenize()`` method to get the filename in the exception message::
+
+    foreach ($files as $file) {
+        try {
+            $twig->parse($twig->tokenize(new Twig_Source($template, $file->getFilename(), $file)));
+
+            // the $template is valid
+        } catch (Twig_Error_Syntax $e) {
+            // $template contains one or more syntax errors
+        }
+    }
+
+.. note::
+
+    This method won't catch any sandbox policy violations because the policy
+    is enforced during template rendering (as Twig needs the context for some
+    checks like allowed methods on objects).
+
+Refreshing modified Templates when OPcache or APC is enabled
+------------------------------------------------------------
+
+When using OPcache with ``opcache.validate_timestamps`` set to ``0`` or APC
+with ``apc.stat`` set to ``0`` and Twig cache enabled, clearing the template
+cache won't update the cache.
+
+To get around this, force Twig to invalidate the bytecode cache::
+
+    $twig = new Twig_Environment($loader, array(
+        'cache' => new Twig_Cache_Filesystem('/some/cache/path', Twig_Cache_Filesystem::FORCE_BYTECODE_INVALIDATION),
+        // ...
+    ));
+
+Reusing a stateful Node Visitor
+-------------------------------
+
+When attaching a visitor to a ``Twig_Environment`` instance, Twig uses it to
+visit *all* templates it compiles. If you need to keep some state information
+around, you probably want to reset it when visiting a new template.
+
+This can be easily achieved with the following code::
+
+    protected $someTemplateState = array();
+
+    public function enterNode(Twig_Node $node, Twig_Environment $env)
+    {
+        if ($node instanceof Twig_Node_Module) {
+            // reset the state as we are entering a new template
+            $this->someTemplateState = array();
+        }
+
+        // ...
+
+        return $node;
+    }
+
+Using a Database to store Templates
+-----------------------------------
+
+If you are developing a CMS, templates are usually stored in a database. This
+recipe gives you a simple PDO template loader you can use as a starting point
+for your own.
+
+First, let's create a temporary in-memory SQLite3 database to work with::
+
+    $dbh = new PDO('sqlite::memory:');
+    $dbh->exec('CREATE TABLE templates (name STRING, source STRING, last_modified INTEGER)');
+    $base = '{% block content %}{% endblock %}';
+    $index = '
+    {% extends "base.twig" %}
+    {% block content %}Hello {{ name }}{% endblock %}
+    ';
+    $now = time();
+    $dbh->exec("INSERT INTO templates (name, source, last_modified) VALUES ('base.twig', '$base', $now)");
+    $dbh->exec("INSERT INTO templates (name, source, last_modified) VALUES ('index.twig', '$index', $now)");
+
+We have created a simple ``templates`` table that hosts two templates:
+``base.twig`` and ``index.twig``.
+
+Now, let's define a loader able to use this database::
+
+    class DatabaseTwigLoader implements Twig_LoaderInterface
+    {
+        protected $dbh;
+
+        public function __construct(PDO $dbh)
+        {
+            $this->dbh = $dbh;
+        }
+
+        public function getSourceContext($name)
+        {
+            if (false === $source = $this->getValue('source', $name)) {
+                throw new Twig_Error_Loader(sprintf('Template "%s" does not exist.', $name));
+            }
+
+            return new Twig_Source($source, $name);
+        }
+
+        public function exists($name)
+        {
+            return $name === $this->getValue('name', $name);
+        }
+
+        public function getCacheKey($name)
+        {
+            return $name;
+        }
+
+        public function isFresh($name, $time)
+        {
+            if (false === $lastModified = $this->getValue('last_modified', $name)) {
+                return false;
+            }
+
+            return $lastModified <= $time;
+        }
+
+        protected function getValue($column, $name)
+        {
+            $sth = $this->dbh->prepare('SELECT '.$column.' FROM templates WHERE name = :name');
+            $sth->execute(array(':name' => (string) $name));
+
+            return $sth->fetchColumn();
+        }
+    }
+
+Finally, here is an example on how you can use it::
+
+    $loader = new DatabaseTwigLoader($dbh);
+    $twig = new Twig_Environment($loader);
+
+    echo $twig->render('index.twig', array('name' => 'Fabien'));
+
+Using different Template Sources
+--------------------------------
+
+This recipe is the continuation of the previous one. Even if you store the
+contributed templates in a database, you might want to keep the original/base
+templates on the filesystem. When templates can be loaded from different
+sources, you need to use the ``Twig_Loader_Chain`` loader.
+
+As you can see in the previous recipe, we reference the template in the exact
+same way as we would have done it with a regular filesystem loader. This is
+the key to be able to mix and match templates coming from the database, the
+filesystem, or any other loader for that matter: the template name should be a
+logical name, and not the path from the filesystem::
+
+    $loader1 = new DatabaseTwigLoader($dbh);
+    $loader2 = new Twig_Loader_Array(array(
+        'base.twig' => '{% block content %}{% endblock %}',
+    ));
+    $loader = new Twig_Loader_Chain(array($loader1, $loader2));
+
+    $twig = new Twig_Environment($loader);
+
+    echo $twig->render('index.twig', array('name' => 'Fabien'));
+
+Now that the ``base.twig`` templates is defined in an array loader, you can
+remove it from the database, and everything else will still work as before.
+
+Loading a Template from a String
+--------------------------------
+
+From a template, you can easily load a template stored in a string via the
+``template_from_string`` function (via the ``Twig_Extension_StringLoader``
+extension):
+
+.. code-block:: jinja
+
+    {{ include(template_from_string("Hello {{ name }}")) }}
+
+From PHP, it's also possible to load a template stored in a string via
+``Twig_Environment::createTemplate()``::
+
+    $template = $twig->createTemplate('hello {{ name }}');
+    echo $template->render(array('name' => 'Fabien'));
+
+Using Twig and AngularJS in the same Templates
+----------------------------------------------
+
+Mixing different template syntaxes in the same file is not a recommended
+practice as both AngularJS and Twig use the same delimiters in their syntax:
+``{{`` and ``}}``.
+
+Still, if you want to use AngularJS and Twig in the same template, there are
+two ways to make it work depending on the amount of AngularJS you need to
+include in your templates:
+
+* Escaping the AngularJS delimiters by wrapping AngularJS sections with the
+  ``{% verbatim %}`` tag or by escaping each delimiter via ``{{ '{{' }}`` and
+  ``{{ '}}' }}``;
+
+* Changing the delimiters of one of the template engines (depending on which
+  engine you introduced last):
+
+  * For AngularJS, change the interpolation tags using the
+    ``interpolateProvider`` service, for instance at the module initialization
+    time:
+
+    ..  code-block:: javascript
+
+        angular.module('myApp', []).config(function($interpolateProvider) {
+            $interpolateProvider.startSymbol('{[').endSymbol(']}');
+        });
+
+  * For Twig, change the delimiters via the ``tag_variable`` Lexer option:
+
+    ..  code-block:: php
+
+        $env->setLexer(new Twig_Lexer($env, array(
+            'tag_variable' => array('{[', ']}'),
+        )));
+

+``autoescape``
+==============
+
+Whether automatic escaping is enabled or not, you can mark a section of a
+template to be escaped or not by using the ``autoescape`` tag:
+
+.. code-block:: jinja
+
+    {% autoescape %}
+        Everything will be automatically escaped in this block
+        using the HTML strategy
+    {% endautoescape %}
+
+    {% autoescape 'html' %}
+        Everything will be automatically escaped in this block
+        using the HTML strategy
+    {% endautoescape %}
+
+    {% autoescape 'js' %}
+        Everything will be automatically escaped in this block
+        using the js escaping strategy
+    {% endautoescape %}
+
+    {% autoescape false %}
+        Everything will be outputted as is in this block
+    {% endautoescape %}
+
+When automatic escaping is enabled everything is escaped by default except for
+values explicitly marked as safe. Those can be marked in the template by using
+the :doc:`raw<../filters/raw>` filter:
+
+.. code-block:: jinja
+
+    {% autoescape %}
+        {{ safe_value|raw }}
+    {% endautoescape %}
+
+Functions returning template data (like :doc:`macros<macro>` and
+:doc:`parent<../functions/parent>`) always return safe markup.
+
+.. note::
+
+    Twig is smart enough to not escape an already escaped value by the
+    :doc:`escape<../filters/escape>` filter.
+
+.. note::
+
+    Twig does not escape static expressions:
+
+    .. code-block:: jinja
+
+        {% set hello = "<strong>Hello</strong>" %}
+        {{ hello }}
+        {{ "<strong>world</strong>" }}
+
+    Will be rendered "<strong>Hello</strong> **world**".
+
+.. note::
+
+    The chapter :doc:`Twig for Developers<../api>` gives more information
+    about when and how automatic escaping is applied.

+``embed``
+=========
+
+The ``embed`` tag combines the behaviour of :doc:`include<include>` and
+:doc:`extends<extends>`.
+It allows you to include another template's contents, just like ``include``
+does. But it also allows you to override any block defined inside the
+included template, like when extending a template.
+
+Think of an embedded template as a "micro layout skeleton".
+
+.. code-block:: jinja
+
+    {% embed "teasers_skeleton.twig" %}
+        {# These blocks are defined in "teasers_skeleton.twig" #}
+        {# and we override them right here:                    #}
+        {% block left_teaser %}
+            Some content for the left teaser box
+        {% endblock %}
+        {% block right_teaser %}
+            Some content for the right teaser box
+        {% endblock %}
+    {% endembed %}
+
+The ``embed`` tag takes the idea of template inheritance to the level of
+content fragments. While template inheritance allows for "document skeletons",
+which are filled with life by child templates, the ``embed`` tag allows you to
+create "skeletons" for smaller units of content and re-use and fill them
+anywhere you like.
+
+Since the use case may not be obvious, let's look at a simplified example.
+Imagine a base template shared by multiple HTML pages, defining a single block
+named "content":
+
+.. code-block:: text
+
+    ┌─── page layout ─────────────────────┐
+    │                                     │
+    │           ┌── block "content" ──┐   │

+    │           │ (child template to  │   │
+    │           │  put content here)  │   │
+    │           │                     │   │
+    │           │                     │   │
+    │           └─────────────────────┘   │
+    │                                     │
+    └─────────────────────────────────────┘
+
+Some pages ("foo" and "bar") share the same content structure -
+two vertically stacked boxes:
+
+.. code-block:: text
+
+    ┌─── page layout ─────────────────────┐
+    │                                     │

+    └─────────────────────────────────────┘
+
+While other pages ("boom" and "baz") share a different content structure -
+two boxes side by side:
+
+.. code-block:: text
+
+    ┌─── page layout ─────────────────────┐
+    │                                     │

+    └─────────────────────────────────────┘
+
+Without the ``embed`` tag, you have two ways to design your templates:
+
+* Create two "intermediate" base templates that extend the master layout
+  template: one with vertically stacked boxes to be used by the "foo" and
+  "bar" pages and another one with side-by-side boxes for the "boom" and
+  "baz" pages.
+
+* Embed the markup for the top/bottom and left/right boxes into each page
+  template directly.
+
+These two solutions do not scale well because they each have a major drawback:
+
+* The first solution may indeed work for this simplified example. But imagine
+  we add a sidebar, which may again contain different, recurring structures
+  of content. Now we would need to create intermediate base templates for
+  all occurring combinations of content structure and sidebar structure...
+  and so on.
+
+* The second solution involves duplication of common code with all its negative
+  consequences: any change involves finding and editing all affected copies
+  of the structure, correctness has to be verified for each copy, copies may
+  go out of sync by careless modifications etc.
+
+In such a situation, the ``embed`` tag comes in handy. The common layout
+code can live in a single base template, and the two different content structures,
+let's call them "micro layouts" go into separate templates which are embedded
+as necessary:
+
+Page template ``foo.twig``:
+
+.. code-block:: jinja
+
+    {% extends "layout_skeleton.twig" %}
+
+    {% block content %}
+        {% embed "vertical_boxes_skeleton.twig" %}
+            {% block top %}
+                Some content for the top box
+            {% endblock %}
+
+            {% block bottom %}
+                Some content for the bottom box
+            {% endblock %}
+        {% endembed %}
+    {% endblock %}
+
+And here is the code for ``vertical_boxes_skeleton.twig``:
+
+.. code-block:: html+jinja
+
+    <div class="top_box">
+        {% block top %}
+            Top box default content
+        {% endblock %}
+    </div>
+
+    <div class="bottom_box">
+        {% block bottom %}
+            Bottom box default content
+        {% endblock %}
+    </div>
+
+The goal of the ``vertical_boxes_skeleton.twig`` template being to factor
+out the HTML markup for the boxes.
+
+The ``embed`` tag takes the exact same arguments as the ``include`` tag:
+
+.. code-block:: jinja
+
+    {% embed "base" with {'foo': 'bar'} %}
+        ...
+    {% endembed %}
+
+    {% embed "base" with {'foo': 'bar'} only %}
+        ...
+    {% endembed %}
+
+    {% embed "base" ignore missing %}
+        ...
+    {% endembed %}
+
+.. warning::
+
+    As embedded templates do not have "names", auto-escaping strategies based
+    on the template name won't work as expected if you change the context (for
+    instance, if you embed a CSS/JavaScript template into an HTML one). In that
+    case, explicitly set the default auto-escaping strategy with the
+    ``autoescape`` tag.

+``extends``
+===========
+
+The ``extends`` tag can be used to extend a template from another one.
+
+.. note::
+
+    Like PHP, Twig does not support multiple inheritance. So you can only have
+    one extends tag called per rendering. However, Twig supports horizontal
+    :doc:`reuse<use>`.
+
+Let's define a base template, ``base.html``, which defines a simple HTML
+skeleton document:
+
+.. code-block:: html+jinja
+
+    <!DOCTYPE html>
+    <html>
+        <head>
+            {% block head %}
+                <link rel="stylesheet" href="style.css" />
+                <title>{% block title %}{% endblock %} - My Webpage</title>
+            {% endblock %}
+        </head>
+        <body>
+            <div id="content">{% block content %}{% endblock %}</div>
+            <div id="footer">
+                {% block footer %}
+                    &copy; Copyright 2011 by <a href="http://domain.invalid/">you</a>.
+                {% endblock %}
+            </div>
+        </body>
+    </html>
+
+In this example, the :doc:`block<block>` tags define four blocks that child
+templates can fill in.
+
+All the ``block`` tag does is to tell the template engine that a child
+template may override those portions of the template.
+
+Child Template
+--------------
+
+A child template might look like this:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% block title %}Index{% endblock %}
+    {% block head %}
+        {{ parent() }}
+        <style type="text/css">
+            .important { color: #336699; }
+        </style>
+    {% endblock %}
+    {% block content %}
+        <h1>Index</h1>
+        <p class="important">
+            Welcome on my awesome homepage.
+        </p>
+    {% endblock %}
+
+The ``extends`` tag is the key here. It tells the template engine that this
+template "extends" another template. When the template system evaluates this
+template, first it locates the parent. The extends tag should be the first tag
+in the template.
+
+Note that since the child template doesn't define the ``footer`` block, the
+value from the parent template is used instead.
+
+You can't define multiple ``block`` tags with the same name in the same
+template. This limitation exists because a block tag works in "both"
+directions. That is, a block tag doesn't just provide a hole to fill - it also
+defines the content that fills the hole in the *parent*. If there were two
+similarly-named ``block`` tags in a template, that template's parent wouldn't
+know which one of the blocks' content to use.
+
+If you want to print a block multiple times you can however use the
+``block`` function:
+
+.. code-block:: jinja
+
+    <title>{% block title %}{% endblock %}</title>
+    <h1>{{ block('title') }}</h1>
+    {% block body %}{% endblock %}
+
+Parent Blocks
+-------------
+
+It's possible to render the contents of the parent block by using the
+:doc:`parent<../functions/parent>` function. This gives back the results of
+the parent block:
+
+.. code-block:: jinja
+
+    {% block sidebar %}
+        <h3>Table Of Contents</h3>
+        ...
+        {{ parent() }}
+    {% endblock %}
+
+Named Block End-Tags
+--------------------
+
+Twig allows you to put the name of the block after the end tag for better
+readability:
+
+.. code-block:: jinja
+
+    {% block sidebar %}
+        {% block inner_sidebar %}
+            ...
+        {% endblock inner_sidebar %}
+    {% endblock sidebar %}
+
+Of course, the name after the ``endblock`` word must match the block name.
+
+Block Nesting and Scope
+-----------------------
+
+Blocks can be nested for more complex layouts. Per default, blocks have access
+to variables from outer scopes:
+
+.. code-block:: jinja
+
+    {% for item in seq %}
+        <li>{% block loop_item %}{{ item }}{% endblock %}</li>
+    {% endfor %}
+
+Block Shortcuts
+---------------
+
+For blocks with little content, it's possible to use a shortcut syntax. The
+following constructs do the same thing:
+
+.. code-block:: jinja
+
+    {% block title %}
+        {{ page_title|title }}
+    {% endblock %}
+
+.. code-block:: jinja
+
+    {% block title page_title|title %}
+
+Dynamic Inheritance
+-------------------
+
+Twig supports dynamic inheritance by using a variable as the base template:
+
+.. code-block:: jinja
+
+    {% extends some_var %}
+
+If the variable evaluates to a ``Twig_Template`` or a ``Twig_TemplateWrapper``
+instance, Twig will use it as the parent template::
+
+    // {% extends layout %}
+
+    $layout = $twig->load('some_layout_template.twig');
+
+    $twig->display('template.twig', array('layout' => $layout));
+
+You can also provide a list of templates that are checked for existence. The
+first template that exists will be used as a parent:
+
+.. code-block:: jinja
+
+    {% extends ['layout.html', 'base_layout.html'] %}
+
+Conditional Inheritance
+-----------------------
+
+As the template name for the parent can be any valid Twig expression, it's
+possible to make the inheritance mechanism conditional:
+
+.. code-block:: jinja
+
+    {% extends standalone ? "minimum.html" : "base.html" %}
+
+In this example, the template will extend the "minimum.html" layout template
+if the ``standalone`` variable evaluates to ``true``, and "base.html"
+otherwise.
+
+How do blocks work?
+-------------------
+
+A block provides a way to change how a certain part of a template is rendered
+but it does not interfere in any way with the logic around it.
+
+Let's take the following example to illustrate how a block works and more
+importantly, how it does not work:
+
+.. code-block:: jinja
+
+    {# base.twig #}
+
+    {% for post in posts %}
+        {% block post %}
+            <h1>{{ post.title }}</h1>
+            <p>{{ post.body }}</p>
+        {% endblock %}
+    {% endfor %}
+
+If you render this template, the result would be exactly the same with or
+without the ``block`` tag. The ``block`` inside the ``for`` loop is just a way
+to make it overridable by a child template:
+
+.. code-block:: jinja
+
+    {# child.twig #}
+
+    {% extends "base.twig" %}
+
+    {% block post %}
+        <article>
+            <header>{{ post.title }}</header>
+            <section>{{ post.text }}</section>
+        </article>
+    {% endblock %}
+
+Now, when rendering the child template, the loop is going to use the block
+defined in the child template instead of the one defined in the base one; the
+executed template is then equivalent to the following one:
+
+.. code-block:: jinja
+
+    {% for post in posts %}
+        <article>
+            <header>{{ post.title }}</header>
+            <section>{{ post.text }}</section>
+        </article>
+    {% endfor %}
+
+Let's take another example: a block included within an ``if`` statement:
+
+.. code-block:: jinja
+
+    {% if posts is empty %}
+        {% block head %}
+            {{ parent() }}
+
+            <meta name="robots" content="noindex, follow">
+        {% endblock head %}
+    {% endif %}
+
+Contrary to what you might think, this template does not define a block
+conditionally; it just makes overridable by a child template the output of
+what will be rendered when the condition is ``true``.
+
+If you want the output to be displayed conditionally, use the following
+instead:
+
+.. code-block:: jinja
+
+    {% block head %}
+        {{ parent() }}
+
+        {% if posts is empty %}
+            <meta name="robots" content="noindex, follow">
+        {% endif %}
+    {% endblock head %}
+
+.. seealso:: :doc:`block<../functions/block>`, :doc:`block<../tags/block>`, :doc:`parent<../functions/parent>`, :doc:`use<../tags/use>`

+        {% for user in users %}

+    </ul>
+
+.. note::
+
+    A sequence can be either an array or an object implementing the

+
+If you do need to iterate over a sequence of numbers, you can use the ``..``

+
+.. code-block:: jinja
+
+    {% for i in 0..10 %}
+        * {{ i }}
+    {% endfor %}

+
+.. code-block:: jinja
+
+    {% for letter in 'a'..'z' %}
+        * {{ letter }}
+    {% endfor %}

+
+.. code-block:: jinja
+
+    {% for letter in 'a'|upper..'z'|upper %}
+        * {{ letter }}
+    {% endfor %}
+
+.. tip:
+
+    If you need a step different from 1, you can use the ``range`` function
+    instead.
+
+The `loop` variable
+-------------------
+
+Inside of a ``for`` loop block you can access some special variables:
+
+===================== =============================================================
+Variable              Description
+===================== =============================================================
+``loop.index``        The current iteration of the loop. (1 indexed)
+``loop.index0``       The current iteration of the loop. (0 indexed)
+``loop.revindex``     The number of iterations from the end of the loop (1 indexed)
+``loop.revindex0``    The number of iterations from the end of the loop (0 indexed)
+``loop.first``        True if first iteration
+``loop.last``         True if last iteration
+``loop.length``       The number of items in the sequence
+``loop.parent``       The parent context
+===================== =============================================================
+
+.. code-block:: jinja
+
+    {% for user in users %}
+        {{ loop.index }} - {{ user.username }}
+    {% endfor %}
+
+.. note::
+
+    The ``loop.length``, ``loop.revindex``, ``loop.revindex0``, and
+    ``loop.last`` variables are only available for PHP arrays, or objects that
+    implement the ``Countable`` interface. They are also not available when
+    looping with a condition.
+
+Adding a condition
+------------------
+
+Unlike in PHP, it's not possible to ``break`` or ``continue`` in a loop. You
+can however filter the sequence during iteration which allows you to skip
+items. The following example skips all the users which are not active:
+
+.. code-block:: jinja
+
+    <ul>
+        {% for user in users if user.active %}
+            <li>{{ user.username|e }}</li>
+        {% endfor %}
+    </ul>
+
+The advantage is that the special loop variable will count correctly thus not
+counting the users not iterated over. Keep in mind that properties like
+``loop.last`` will not be defined when using loop conditions.
+
+.. note::
+
+    Using the ``loop`` variable within the condition is not recommended as it
+    will probably not be doing what you expect it to. For instance, adding a
+    condition like ``loop.index > 4`` won't work as the index is only
+    incremented when the condition is true (so the condition will never
+    match).
+
+The `else` Clause
+-----------------
+
+If no iteration took place because the sequence was empty, you can render a
+replacement block by using ``else``:
+
+.. code-block:: jinja
+
+    <ul>
+        {% for user in users %}
+            <li>{{ user.username|e }}</li>
+        {% else %}
+            <li><em>no user found</em></li>
+        {% endfor %}
+    </ul>
+
+Iterating over Keys
+-------------------
+
+By default, a loop iterates over the values of the sequence. You can iterate
+on keys by using the ``keys`` filter:
+
+.. code-block:: jinja
+
+    <h1>Members</h1>
+    <ul>
+        {% for key in users|keys %}
+            <li>{{ key }}</li>
+        {% endfor %}
+    </ul>
+
+Iterating over Keys and Values
+------------------------------
+
+You can also access both keys and values:
+
+.. code-block:: jinja
+
+    <h1>Members</h1>
+    <ul>
+        {% for key, user in users %}
+            <li>{{ key }}: {{ user.username|e }}</li>
+        {% endfor %}
+    </ul>
+
+Iterating over a Subset
+-----------------------
+
+You might want to iterate over a subset of values. This can be achieved using
+the :doc:`slice <../filters/slice>` filter:
+
+.. code-block:: jinja
+
+    <h1>Top Ten Members</h1>
+    <ul>
+        {% for user in users|slice(0, 10) %}
+            <li>{{ user.username|e }}</li>
+        {% endfor %}
+    </ul>

+
+.. note::
+
+    If you want to test if the variable is defined, use ``if users is

+
+You can also use ``not`` to check for values that evaluate to ``false``:

+    {% if not user.subscribed %}

+``import``
+==========
+
+Twig supports putting often used code into :doc:`macros<../tags/macro>`. These
+macros can go into different templates and get imported from there.
+
+There are two ways to import templates. You can import the complete template
+into a variable or request specific macros from it.
+
+Imagine we have a helper module that renders forms (called ``forms.html``):
+
+.. code-block:: jinja
+
+    {% macro input(name, value, type, size) %}
+        <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
+    {% endmacro %}
+
+    {% macro textarea(name, value, rows, cols) %}
+        <textarea name="{{ name }}" rows="{{ rows|default(10) }}" cols="{{ cols|default(40) }}">{{ value|e }}</textarea>
+    {% endmacro %}
+
+The easiest and most flexible is importing the whole module into a variable.
+That way you can access the attributes:
+
+.. code-block:: jinja
+
+    {% import 'forms.html' as forms %}
+
+    <dl>
+        <dt>Username</dt>
+        <dd>{{ forms.input('username') }}</dd>
+        <dt>Password</dt>
+        <dd>{{ forms.input('password', null, 'password') }}</dd>
+    </dl>
+    <p>{{ forms.textarea('comment') }}</p>
+
+Alternatively you can import names from the template into the current
+namespace:
+
+.. code-block:: jinja
+
+    {% from 'forms.html' import input as input_field, textarea %}
+
+    <dl>
+        <dt>Username</dt>
+        <dd>{{ input_field('username') }}</dd>
+        <dt>Password</dt>
+        <dd>{{ input_field('password', '', 'password') }}</dd>
+    </dl>
+    <p>{{ textarea('comment') }}</p>
+
+.. tip::
+
+    To import macros from the current file, use the special ``_self`` variable
+    for the source.
+
+.. seealso:: :doc:`macro<../tags/macro>`, :doc:`from<../tags/from>`

+``include``
+===========
+
+The ``include`` statement includes a template and returns the rendered content
+of that file into the current namespace:
+
+.. code-block:: jinja
+
+    {% include 'header.html' %}
+        Body
+    {% include 'footer.html' %}
+
+Included templates have access to the variables of the active context.
+
+If you are using the filesystem loader, the templates are looked for in the
+paths defined by it.
+
+You can add additional variables by passing them after the ``with`` keyword:
+
+.. code-block:: jinja
+
+    {# template.html will have access to the variables from the current context and the additional ones provided #}
+    {% include 'template.html' with {'foo': 'bar'} %}
+
+    {% set vars = {'foo': 'bar'} %}
+    {% include 'template.html' with vars %}
+
+You can disable access to the context by appending the ``only`` keyword:
+
+.. code-block:: jinja
+
+    {# only the foo variable will be accessible #}
+    {% include 'template.html' with {'foo': 'bar'} only %}
+
+.. code-block:: jinja
+
+    {# no variables will be accessible #}
+    {% include 'template.html' only %}
+
+.. tip::
+
+    When including a template created by an end user, you should consider
+    sandboxing it. More information in the :doc:`Twig for Developers<../api>`
+    chapter and in the :doc:`sandbox<../tags/sandbox>` tag documentation.
+
+The template name can be any valid Twig expression:
+
+.. code-block:: jinja
+
+    {% include some_var %}
+    {% include ajax ? 'ajax.html' : 'not_ajax.html' %}
+
+And if the expression evaluates to a ``Twig_Template`` or a
+``Twig_TemplateWrapper`` instance, Twig will use it directly::
+
+    // {% include template %}
+
+    $template = $twig->load('some_template.twig');
+
+    $twig->display('template.twig', array('template' => $template));
+
+You can mark an include with ``ignore missing`` in which case Twig will ignore
+the statement if the template to be included does not exist. It has to be
+placed just after the template name. Here some valid examples:
+
+.. code-block:: jinja
+
+    {% include 'sidebar.html' ignore missing %}
+    {% include 'sidebar.html' ignore missing with {'foo': 'bar'} %}
+    {% include 'sidebar.html' ignore missing only %}
+
+You can also provide a list of templates that are checked for existence before
+inclusion. The first template that exists will be included:
+
+.. code-block:: jinja
+
+    {% include ['page_detailed.html', 'page.html'] %}
+
+If ``ignore missing`` is given, it will fall back to rendering nothing if none
+of the templates exist, otherwise it will throw an exception.

+``macro``
+=========
+
+Macros are comparable with functions in regular programming languages. They
+are useful to put often used HTML idioms into reusable elements to not repeat
+yourself.
+
+Here is a small example of a macro that renders a form element:
+
+.. code-block:: jinja
+
+    {% macro input(name, value, type, size) %}
+        <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
+    {% endmacro %}
+
+Macros differ from native PHP functions in a few ways:
+
+* Default argument values are defined by using the ``default`` filter in the
+  macro body;
+
+* Arguments of a macro are always optional.
+
+* If extra positional arguments are passed to a macro, they end up in the
+  special ``varargs`` variable as a list of values.
+
+But as with PHP functions, macros don't have access to the current template
+variables.
+
+.. tip::
+
+    You can pass the whole context as an argument by using the special
+    ``_context`` variable.
+
+Import
+------
+
+Macros can be defined in any template, and need to be "imported" before being
+used (see the documentation for the :doc:`import<../tags/import>` tag for more
+information):
+
+.. code-block:: jinja
+
+    {% import "forms.html" as forms %}
+
+The above ``import`` call imports the "forms.html" file (which can contain only
+macros, or a template and some macros), and import the functions as items of
+the ``forms`` variable.
+
+The macro can then be called at will:
+
+.. code-block:: jinja
+
+    <p>{{ forms.input('username') }}</p>
+    <p>{{ forms.input('password', null, 'password') }}</p>
+
+If macros are defined and used in the same template, you can use the
+special ``_self`` variable to import them:
+
+.. code-block:: jinja
+
+    {% import _self as forms %}
+
+    <p>{{ forms.input('username') }}</p>
+
+When you want to use a macro in another macro from the same file, you need to
+import it locally:
+
+.. code-block:: jinja
+
+    {% macro input(name, value, type, size) %}
+        <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
+    {% endmacro %}
+
+    {% macro wrapped_input(name, value, type, size) %}
+        {% import _self as forms %}
+
+        <div class="field">
+            {{ forms.input(name, value, type, size) }}
+        </div>
+    {% endmacro %}
+
+Named Macro End-Tags
+--------------------
+
+Twig allows you to put the name of the macro after the end tag for better
+readability:
+
+.. code-block:: jinja
+
+    {% macro input() %}
+        ...
+    {% endmacro input %}
+
+Of course, the name after the ``endmacro`` word must match the macro name.

+``set``
+=======
+
+Inside code blocks you can also assign values to variables. Assignments use
+the ``set`` tag and can have multiple targets.
+
+Here is how you can assign the ``bar`` value to the ``foo`` variable:
+
+.. code-block:: jinja
+
+    {% set foo = 'bar' %}
+
+After the ``set`` call, the ``foo`` variable is available in the template like
+any other ones:
+
+.. code-block:: jinja
+
+    {# displays bar #}
+    {{ foo }}
+
+The assigned value can be any valid :ref:`Twig expressions
+<twig-expressions>`:
+
+.. code-block:: jinja
+
+    {% set foo = [1, 2] %}
+    {% set foo = {'foo': 'bar'} %}
+    {% set foo = 'foo' ~ 'bar' %}
+
+Several variables can be assigned in one block:
+
+.. code-block:: jinja
+
+    {% set foo, bar = 'foo', 'bar' %}
+
+    {# is equivalent to #}
+
+    {% set foo = 'foo' %}
+    {% set bar = 'bar' %}
+
+The ``set`` tag can also be used to 'capture' chunks of text:
+
+.. code-block:: jinja
+
+    {% set foo %}
+        <div id="pagination">
+            ...
+        </div>
+    {% endset %}
+
+.. caution::
+
+    If you enable automatic output escaping, Twig will only consider the
+    content to be safe when capturing chunks of text.
+
+.. note::
+
+    Note that loops are scoped in Twig; therefore a variable declared inside a
+    ``for`` loop is not accessible outside the loop itself:
+
+    .. code-block:: jinja
+
+        {% for item in list %}
+            {% set foo = item %}
+        {% endfor %}
+
+        {# foo is NOT available #}
+
+    If you want to access the variable, just declare it before the loop:
+
+    .. code-block:: jinja
+
+        {% set foo = "" %}
+        {% for item in list %}
+            {% set foo = item %}

+``spaceless``
+=============
+
+Use the ``spaceless`` tag to remove whitespace *between HTML tags*, not

+
+This tag is not meant to "optimize" the size of the generated HTML content but
+merely to avoid extra whitespace between HTML tags to avoid browser rendering
+quirks under some circumstances.
+
+.. tip::
+
+    If you want to optimize the size of the generated HTML content, gzip
+    compress the output instead.
+
+.. tip::
+
+    If you want to create a tag that actually removes all extra whitespace in
+    an HTML string, be warned that this is not as easy as it seems to be
+    (think of ``textarea`` or ``pre`` tags for instance). Using a third-party
+    library like Tidy is probably a better idea.
+
+.. tip::
+
+    For more information on whitespace control, read the
+    :ref:`dedicated section <templates-whitespace-control>` of the documentation and learn how
+    you can also use the whitespace control modifier on your tags.

+``use``
+=======
+
+.. note::
+
+    Horizontal reuse is an advanced Twig feature that is hardly ever needed in
+    regular templates. It is mainly used by projects that need to make
+    template blocks reusable without using inheritance.
+
+Template inheritance is one of the most powerful features of Twig but it is
+limited to single inheritance; a template can only extend one other template.
+This limitation makes template inheritance simple to understand and easy to
+debug:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+Horizontal reuse is a way to achieve the same goal as multiple inheritance,
+but without the associated complexity:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% use "blocks.html" %}
+
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+The ``use`` statement tells Twig to import the blocks defined in
+``blocks.html`` into the current template (it's like macros, but for blocks):
+
+.. code-block:: jinja
+
+    {# blocks.html #}
+    
+    {% block sidebar %}{% endblock %}
+
+In this example, the ``use`` statement imports the ``sidebar`` block into the
+main template. The code is mostly equivalent to the following one (the
+imported blocks are not outputted automatically):
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% block sidebar %}{% endblock %}
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+.. note::
+
+    The ``use`` tag only imports a template if it does not extend another
+    template, if it does not define macros, and if the body is empty. But it
+    can *use* other templates.
+
+.. note::
+
+    Because ``use`` statements are resolved independently of the context
+    passed to the template, the template reference cannot be an expression.
+
+The main template can also override any imported block. If the template
+already defines the ``sidebar`` block, then the one defined in ``blocks.html``
+is ignored. To avoid name conflicts, you can rename imported blocks:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% use "blocks.html" with sidebar as base_sidebar, title as base_title %}
+
+    {% block sidebar %}{% endblock %}
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+The ``parent()`` function automatically determines the correct inheritance
+tree, so it can be used when overriding a block defined in an imported
+template:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% use "blocks.html" %}
+
+    {% block sidebar %}
+        {{ parent() }}
+    {% endblock %}
+
+    {% block title %}{% endblock %}
+    {% block content %}{% endblock %}
+
+In this example, ``parent()`` will correctly call the ``sidebar`` block from
+the ``blocks.html`` template.
+
+.. tip::
+
+    Renaming allows you to simulate inheritance by calling the "parent" block:
+
+    .. code-block:: jinja
+
+        {% extends "base.html" %}
+
+        {% use "blocks.html" with sidebar as parent_sidebar %}
+
+        {% block sidebar %}
+            {{ block('parent_sidebar') }}
+        {% endblock %}
+
+.. note::
+
+    You can use as many ``use`` statements as you want in any given template.
+    If two imported templates define the same block, the latest one wins.

+``with``
+========
+
+Use the ``with`` tag to create a new inner scope. Variables set within this
+scope are not visible outside of the scope:
+
+.. code-block:: jinja
+
+    {% with %}
+        {% set foo = 42 %}
+        {{ foo }}           foo is 42 here
+    {% endwith %}
+    foo is not visible here any longer
+
+Instead of defining variables at the beginning of the scope, you can pass a
+hash of variables you want to define in the ``with`` tag; the previous example
+is equivalent to the following one:
+
+.. code-block:: jinja
+
+    {% with { foo: 42 } %}
+        {{ foo }}           foo is 42 here

+    {% set vars = { foo: 42 } %}
+    {% with vars %}
+        ...
+    {% endwith %}
+
+By default, the inner scope has access to the outer scope context; you can
+disable this behavior by appending the ``only`` keyword:
+
+.. code-block:: jinja
+
+    {% set bar = 'bar' %}
+    {% with { foo: 42 } only %}

+Twig for Template Designers
+===========================
+
+This document describes the syntax and semantics of the template engine and
+will be most useful as reference to those creating Twig templates.
+
+Synopsis
+--------
+
+A template is simply a text file. It can generate any text-based format (HTML,
+XML, CSV, LaTeX, etc.). It doesn't have a specific extension, ``.html`` or
+``.xml`` are just fine.
+
+A template contains **variables** or **expressions**, which get replaced with
+values when the template is evaluated, and **tags**, which control the logic
+of the template.
+
+Below is a minimal template that illustrates a few basics. We will cover further
+details later on:
+
+.. code-block:: html+jinja
+
+    <!DOCTYPE html>
+    <html>
+        <head>
+            <title>My Webpage</title>
+        </head>
+        <body>
+            <ul id="navigation">
+            {% for item in navigation %}
+                <li><a href="{{ item.href }}">{{ item.caption }}</a></li>
+            {% endfor %}
+            </ul>
+
+            <h1>My Webpage</h1>
+            {{ a_variable }}
+        </body>
+    </html>
+
+There are two kinds of delimiters: ``{% ... %}`` and ``{{ ... }}``. The first
+one is used to execute statements such as for-loops, the latter prints the
+result of an expression to the template.
+
+IDEs Integration
+----------------
+
+Many IDEs support syntax highlighting and auto-completion for Twig:
+
+* *Textmate* via the `Twig bundle`_
+* *Vim* via the `Jinja syntax plugin`_ or the `vim-twig plugin`_
+* *Netbeans* via the `Twig syntax plugin`_ (until 7.1, native as of 7.2)
+* *PhpStorm* (native as of 2.1)
+* *Eclipse* via the `Twig plugin`_
+* *Sublime Text* via the `Twig bundle`_
+* *GtkSourceView* via the `Twig language definition`_ (used by gedit and other projects)
+* *Coda* and *SubEthaEdit* via the `Twig syntax mode`_
+* *Coda 2* via the `other Twig syntax mode`_
+* *Komodo* and *Komodo Edit* via the Twig highlight/syntax check mode
+* *Notepad++* via the `Notepad++ Twig Highlighter`_
+* *Emacs* via `web-mode.el`_
+* *Atom* via the `PHP-twig for atom`_
+* *Visual Studio Code* via the `Twig pack`_
+
+Also, `TwigFiddle`_ is an online service that allows you to execute Twig templates
+from a browser; it supports all versions of Twig.
+
+Variables
+---------
+
+The application passes variables to the templates for manipulation in the
+template. Variables may have attributes or elements you can access,
+too. The visual representation of a variable depends heavily on the application providing
+it.
+
+You can use a dot (``.``) to access attributes of a variable (methods or
+properties of a PHP object, or items of a PHP array), or the so-called
+"subscript" syntax (``[]``):
+
+.. code-block:: jinja
+
+    {{ foo.bar }}
+    {{ foo['bar'] }}
+
+When the attribute contains special characters (like ``-`` that would be
+interpreted as the minus operator), use the ``attribute`` function instead to
+access the variable attribute:
+
+.. code-block:: jinja
+
+    {# equivalent to the non-working foo.data-foo #}
+    {{ attribute(foo, 'data-foo') }}
+
+.. note::
+
+    It's important to know that the curly braces are *not* part of the
+    variable but the print statement. When accessing variables inside tags,
+    don't put the braces around them.
+
+If a variable or attribute does not exist, you will receive a ``null`` value
+when the ``strict_variables`` option is set to ``false``; alternatively, if ``strict_variables``
+is set, Twig will throw an error (see :ref:`environment options<environment_options>`).
+
+.. sidebar:: Implementation
+
+    For convenience's sake ``foo.bar`` does the following things on the PHP
+    layer:
+
+    * check if ``foo`` is an array and ``bar`` a valid element;
+    * if not, and if ``foo`` is an object, check that ``bar`` is a valid property;
+    * if not, and if ``foo`` is an object, check that ``bar`` is a valid method
+      (even if ``bar`` is the constructor - use ``__construct()`` instead);
+    * if not, and if ``foo`` is an object, check that ``getBar`` is a valid method;
+    * if not, and if ``foo`` is an object, check that ``isBar`` is a valid method;
+    * if not, and if ``foo`` is an object, check that ``hasBar`` is a valid method;
+    * if not, return a ``null`` value.
+
+    ``foo['bar']`` on the other hand only works with PHP arrays:
+
+    * check if ``foo`` is an array and ``bar`` a valid element;
+    * if not, return a ``null`` value.
+
+.. note::
+
+    If you want to access a dynamic attribute of a variable, use the
+    :doc:`attribute<functions/attribute>` function instead.
+
+Global Variables
+~~~~~~~~~~~~~~~~
+
+The following variables are always available in templates:
+
+* ``_self``: references the current template name;
+* ``_context``: references the current context;
+* ``_charset``: references the current charset.
+
+Setting Variables
+~~~~~~~~~~~~~~~~~
+
+You can assign values to variables inside code blocks. Assignments use the
+:doc:`set<tags/set>` tag:
+
+.. code-block:: jinja
+
+    {% set foo = 'foo' %}
+    {% set foo = [1, 2] %}
+    {% set foo = {'foo': 'bar'} %}
+
+Filters
+-------
+
+Variables can be modified by **filters**. Filters are separated from the
+variable by a pipe symbol (``|``) and may have optional arguments in
+parentheses. Multiple filters can be chained. The output of one filter is
+applied to the next.
+
+The following example removes all HTML tags from the ``name`` and title-cases
+it:
+
+.. code-block:: jinja
+
+    {{ name|striptags|title }}
+
+Filters that accept arguments have parentheses around the arguments. This
+example will join a list by commas:
+
+.. code-block:: jinja
+
+    {{ list|join(', ') }}
+
+To apply a filter on a section of code, wrap it in the
+:doc:`filter<tags/filter>` tag:
+
+.. code-block:: jinja
+
+    {% filter upper %}
+        This text becomes uppercase
+    {% endfilter %}
+
+Go to the :doc:`filters<filters/index>` page to learn more about built-in
+filters.
+
+Functions
+---------
+
+Functions can be called to generate content. Functions are called by their
+name followed by parentheses (``()``) and may have arguments.
+
+For instance, the ``range`` function returns a list containing an arithmetic
+progression of integers:
+
+.. code-block:: jinja
+
+    {% for i in range(0, 3) %}
+        {{ i }},
+    {% endfor %}
+
+Go to the :doc:`functions<functions/index>` page to learn more about the
+built-in functions.
+
+Named Arguments
+---------------
+
+.. code-block:: jinja
+
+    {% for i in range(low=1, high=10, step=2) %}
+        {{ i }},
+    {% endfor %}
+
+Using named arguments makes your templates more explicit about the meaning of
+the values you pass as arguments:
+
+.. code-block:: jinja
+
+    {{ data|convert_encoding('UTF-8', 'iso-2022-jp') }}
+
+    {# versus #}
+
+    {{ data|convert_encoding(from='iso-2022-jp', to='UTF-8') }}
+
+Named arguments also allow you to skip some arguments for which you don't want
+to change the default value:
+
+.. code-block:: jinja
+
+    {# the first argument is the date format, which defaults to the global date format if null is passed #}
+    {{ "now"|date(null, "Europe/Paris") }}
+
+    {# or skip the format value by using a named argument for the time zone #}
+    {{ "now"|date(timezone="Europe/Paris") }}
+
+You can also use both positional and named arguments in one call, in which
+case positional arguments must always come before named arguments:
+
+.. code-block:: jinja
+
+    {{ "now"|date('d/m/Y H:i', timezone="Europe/Paris") }}
+
+.. tip::
+
+    Each function and filter documentation page has a section where the names
+    of all arguments are listed when supported.
+
+Control Structure
+-----------------
+
+A control structure refers to all those things that control the flow of a
+program - conditionals (i.e. ``if``/``elseif``/``else``), ``for``-loops, as
+well as things like blocks. Control structures appear inside ``{% ... %}``
+blocks.
+
+For example, to display a list of users provided in a variable called
+``users``, use the :doc:`for<tags/for>` tag:
+
+.. code-block:: jinja
+
+    <h1>Members</h1>
+    <ul>
+        {% for user in users %}
+            <li>{{ user.username|e }}</li>
+        {% endfor %}
+    </ul>
+
+The :doc:`if<tags/if>` tag can be used to test an expression:
+
+.. code-block:: jinja
+
+    {% if users|length > 0 %}
+        <ul>
+            {% for user in users %}
+                <li>{{ user.username|e }}</li>
+            {% endfor %}
+        </ul>
+    {% endif %}
+
+Go to the :doc:`tags<tags/index>` page to learn more about the built-in tags.
+
+Comments
+--------
+
+To comment-out part of a line in a template, use the comment syntax ``{# ...
+#}``. This is useful for debugging or to add information for other template
+designers or yourself:
+
+.. code-block:: jinja
+
+    {# note: disabled template because we no longer use this
+        {% for user in users %}
+            ...
+        {% endfor %}
+    #}
+
+Including other Templates
+-------------------------
+
+The :doc:`include<functions/include>` function is useful to include a template
+and return the rendered content of that template into the current one:
+
+.. code-block:: jinja
+
+    {{ include('sidebar.html') }}
+
+By default, included templates have access to the same context as the template
+which includes them. This means that any variable defined in the main template
+will be available in the included template too:
+
+.. code-block:: jinja
+
+    {% for box in boxes %}
+        {{ include('render_box.html') }}
+    {% endfor %}
+
+The included template ``render_box.html`` is able to access the ``box`` variable.
+
+The name of the template depends on the template loader. For instance, the
+``Twig_Loader_Filesystem`` allows you to access other templates by giving the
+filename. You can access templates in subdirectories with a slash:
+
+.. code-block:: jinja
+
+    {{ include('sections/articles/sidebar.html') }}
+
+This behavior depends on the application embedding Twig.
+
+Template Inheritance
+--------------------
+
+The most powerful part of Twig is template inheritance. Template inheritance
+allows you to build a base "skeleton" template that contains all the common
+elements of your site and defines **blocks** that child templates can
+override.
+
+Sounds complicated but it is very basic. It's easier to understand it by
+starting with an example.
+
+Let's define a base template, ``base.html``, which defines a simple HTML
+skeleton document that you might use for a simple two-column page:
+
+.. code-block:: html+jinja
+
+    <!DOCTYPE html>
+    <html>
+        <head>
+            {% block head %}
+                <link rel="stylesheet" href="style.css" />
+                <title>{% block title %}{% endblock %} - My Webpage</title>
+            {% endblock %}
+        </head>
+        <body>
+            <div id="content">{% block content %}{% endblock %}</div>
+            <div id="footer">
+                {% block footer %}
+                    &copy; Copyright 2011 by <a href="http://domain.invalid/">you</a>.
+                {% endblock %}
+            </div>
+        </body>
+    </html>
+
+In this example, the :doc:`block<tags/block>` tags define four blocks that
+child templates can fill in. All the ``block`` tag does is to tell the
+template engine that a child template may override those portions of the
+template.
+
+A child template might look like this:
+
+.. code-block:: jinja
+
+    {% extends "base.html" %}
+
+    {% block title %}Index{% endblock %}
+    {% block head %}
+        {{ parent() }}
+        <style type="text/css">
+            .important { color: #336699; }
+        </style>
+    {% endblock %}
+    {% block content %}
+        <h1>Index</h1>
+        <p class="important">
+            Welcome to my awesome homepage.
+        </p>
+    {% endblock %}
+
+The :doc:`extends<tags/extends>` tag is the key here. It tells the template
+engine that this template "extends" another template. When the template system
+evaluates this template, first it locates the parent. The extends tag should
+be the first tag in the template.
+
+Note that since the child template doesn't define the ``footer`` block, the
+value from the parent template is used instead.
+
+It's possible to render the contents of the parent block by using the
+:doc:`parent<functions/parent>` function. This gives back the results of the
+parent block:
+
+.. code-block:: jinja
+
+    {% block sidebar %}
+        <h3>Table Of Contents</h3>
+        ...
+        {{ parent() }}
+    {% endblock %}
+
+.. tip::
+
+    The documentation page for the :doc:`extends<tags/extends>` tag describes
+    more advanced features like block nesting, scope, dynamic inheritance, and
+    conditional inheritance.
+
+.. note::
+
+    Twig also supports multiple inheritance with the so called horizontal reuse
+    with the help of the :doc:`use<tags/use>` tag. This is an advanced feature
+    hardly ever needed in regular templates.
+
+HTML Escaping
+-------------
+
+When generating HTML from templates, there's always a risk that a variable
+will include characters that affect the resulting HTML. There are two
+approaches: manually escaping each variable or automatically escaping
+everything by default.
+
+Twig supports both, automatic escaping is enabled by default.
+
+The automatic escaping strategy can be configured via the
+:ref:`autoescape<environment_options>` option and defaults to ``html``.
+
+Working with Manual Escaping
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If manual escaping is enabled, it is **your** responsibility to escape
+variables if needed. What to escape? Any variable you don't trust.
+
+Escaping works by piping the variable through the
+:doc:`escape<filters/escape>` or ``e`` filter:
+
+.. code-block:: jinja
+
+    {{ user.username|e }}
+
+By default, the ``escape`` filter uses the ``html`` strategy, but depending on
+the escaping context, you might want to explicitly use any other available
+strategies:
+
+.. code-block:: jinja
+
+    {{ user.username|e('js') }}
+    {{ user.username|e('css') }}
+    {{ user.username|e('url') }}
+    {{ user.username|e('html_attr') }}
+
+Working with Automatic Escaping
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Whether automatic escaping is enabled or not, you can mark a section of a
+template to be escaped or not by using the :doc:`autoescape<tags/autoescape>`
+tag:
+
+.. code-block:: jinja
+
+    {% autoescape %}
+        Everything will be automatically escaped in this block (using the HTML strategy)
+    {% endautoescape %}
+
+By default, auto-escaping uses the ``html`` escaping strategy. If you output
+variables in other contexts, you need to explicitly escape them with the
+appropriate escaping strategy:
+
+.. code-block:: jinja
+
+    {% autoescape 'js' %}
+        Everything will be automatically escaped in this block (using the JS strategy)
+    {% endautoescape %}
+
+Escaping
+--------
+
+It is sometimes desirable or even necessary to have Twig ignore parts it would
+otherwise handle as variables or blocks. For example if the default syntax is
+used and you want to use ``{{`` as raw string in the template and not start a
+variable you have to use a trick.
+
+The easiest way is to output the variable delimiter (``{{``) by using a variable
+expression:
+
+.. code-block:: jinja
+
+    {{ '{{' }}
+
+For bigger sections it makes sense to mark a block
+:doc:`verbatim<tags/verbatim>`.
+
+Macros
+------
+
+Macros are comparable with functions in regular programming languages. They
+are useful to reuse often used HTML fragments to not repeat yourself.
+
+A macro is defined via the :doc:`macro<tags/macro>` tag. Here is a small example
+(subsequently called ``forms.html``) of a macro that renders a form element:
+
+.. code-block:: jinja
+
+    {% macro input(name, value, type, size) %}
+        <input type="{{ type|default('text') }}" name="{{ name }}" value="{{ value|e }}" size="{{ size|default(20) }}" />
+    {% endmacro %}
+
+Macros can be defined in any template, and need to be "imported" via the
+:doc:`import<tags/import>` tag before being used:
+
+.. code-block:: jinja
+
+    {% import "forms.html" as forms %}
+
+    <p>{{ forms.input('username') }}</p>
+
+Alternatively, you can import individual macro names from a template into the
+current namespace via the :doc:`from<tags/from>` tag and optionally alias them:
+
+.. code-block:: jinja
+
+    {% from 'forms.html' import input as input_field %}
+
+    <dl>
+        <dt>Username</dt>
+        <dd>{{ input_field('username') }}</dd>
+        <dt>Password</dt>
+        <dd>{{ input_field('password', '', 'password') }}</dd>
+    </dl>
+
+A default value can also be defined for macro arguments when not provided in a
+macro call:
+
+.. code-block:: jinja
+
+    {% macro input(name, value = "", type = "text", size = 20) %}
+        <input type="{{ type }}" name="{{ name }}" value="{{ value|e }}" size="{{ size }}" />
+    {% endmacro %}
+
+If extra positional arguments are passed to a macro call, they end up in the
+special ``varargs`` variable as a list of values.
+
+.. _twig-expressions:
+
+Expressions
+-----------
+
+Twig allows expressions everywhere. These work very similar to regular PHP and
+even if you're not working with PHP you should feel comfortable with it.
+
+.. note::
+
+    The operator precedence is as follows, with the lowest-precedence
+    operators listed first: ``b-and``, ``b-xor``, ``b-or``, ``or``, ``and``,
+    ``==``, ``!=``, ``<``, ``>``, ``>=``, ``<=``, ``in``, ``matches``,
+    ``starts with``, ``ends with``, ``..``, ``+``, ``-``, ``~``, ``*``, ``/``,
+    ``//``, ``%``, ``is``, ``**``, ``|``, ``[]``, and ``.``:
+
+    .. code-block:: jinja
+
+        {% set greeting = 'Hello ' %}
+        {% set name = 'Fabien' %}
+
+        {{ greeting ~ name|lower }}   {# Hello fabien #}
+
+        {# use parenthesis to change precedence #}
+        {{ (greeting ~ name)|lower }} {# hello fabien #}
+
+Literals
+~~~~~~~~
+
+The simplest form of expressions are literals. Literals are representations
+for PHP types such as strings, numbers, and arrays. The following literals
+exist:
+
+* ``"Hello World"``: Everything between two double or single quotes is a
+  string. They are useful whenever you need a string in the template (for
+  example as arguments to function calls, filters or just to extend or include
+  a template). A string can contain a delimiter if it is preceded by a
+  backslash (``\``) -- like in ``'It\'s good'``. If the string contains a
+  backslash (e.g. ``'c:\Program Files'``) escape it by doubling it
+  (e.g. ``'c:\\Program Files'``).
+
+* ``42`` / ``42.23``: Integers and floating point numbers are created by just
+  writing the number down. If a dot is present the number is a float,
+  otherwise an integer.
+
+* ``["foo", "bar"]``: Arrays are defined by a sequence of expressions
+  separated by a comma (``,``) and wrapped with squared brackets (``[]``).
+
+* ``{"foo": "bar"}``: Hashes are defined by a list of keys and values
+  separated by a comma (``,``) and wrapped with curly braces (``{}``):
+
+  .. code-block:: jinja
+
+    {# keys as string #}
+    { 'foo': 'foo', 'bar': 'bar' }
+
+    {# keys as names (equivalent to the previous hash) #}
+    { foo: 'foo', bar: 'bar' }
+
+    {# keys as integer #}
+    { 2: 'foo', 4: 'bar' }
+
+    {# keys as expressions (the expression must be enclosed into parentheses) #}
+    {% set foo = 'foo' %}
+    { (foo): 'foo', (1 + 1): 'bar', (foo ~ 'b'): 'baz' }
+
+* ``true`` / ``false``: ``true`` represents the true value, ``false``
+  represents the false value.
+
+* ``null``: ``null`` represents no specific value. This is the value returned
+  when a variable does not exist. ``none`` is an alias for ``null``.
+
+Arrays and hashes can be nested:
+
+.. code-block:: jinja
+
+    {% set foo = [1, {"foo": "bar"}] %}
+
+.. tip::
+
+    Using double-quoted or single-quoted strings has no impact on performance
+    but string interpolation is only supported in double-quoted strings.
+
+Math
+~~~~
+
+Twig allows you to calculate with values. This is rarely useful in templates
+but exists for completeness' sake. The following operators are supported:
+
+* ``+``: Adds two objects together (the operands are casted to numbers). ``{{
+  1 + 1 }}`` is ``2``.
+
+* ``-``: Subtracts the second number from the first one. ``{{ 3 - 2 }}`` is
+  ``1``.
+
+* ``/``: Divides two numbers. The returned value will be a floating point
+  number. ``{{ 1 / 2 }}`` is ``{{ 0.5 }}``.
+
+* ``%``: Calculates the remainder of an integer division. ``{{ 11 % 7 }}`` is
+  ``4``.
+
+* ``//``: Divides two numbers and returns the floored integer result. ``{{ 20
+  // 7 }}`` is ``2``, ``{{ -20  // 7 }}`` is ``-3`` (this is just syntactic
+  sugar for the :doc:`round<filters/round>` filter).
+
+* ``*``: Multiplies the left operand with the right one. ``{{ 2 * 2 }}`` would
+  return ``4``.
+
+* ``**``: Raises the left operand to the power of the right operand. ``{{ 2 **
+  3 }}`` would return ``8``.
+
+Logic
+~~~~~
+
+You can combine multiple expressions with the following operators:
+
+* ``and``: Returns true if the left and the right operands are both true.
+
+* ``or``: Returns true if the left or the right operand is true.
+
+* ``not``: Negates a statement.
+
+* ``(expr)``: Groups an expression.
+
+.. note::
+
+    Twig also support bitwise operators (``b-and``, ``b-xor``, and ``b-or``).
+
+.. note::
+
+    Operators are case sensitive.
+
+Comparisons
+~~~~~~~~~~~
+
+The following comparison operators are supported in any expression: ``==``,
+``!=``, ``<``, ``>``, ``>=``, and ``<=``.
+
+You can also check if a string ``starts with`` or ``ends with`` another
+string:
+
+.. code-block:: jinja
+
+    {% if 'Fabien' starts with 'F' %}
+    {% endif %}
+
+    {% if 'Fabien' ends with 'n' %}
+    {% endif %}
+
+.. note::
+
+    For complex string comparisons, the ``matches`` operator allows you to use
+    `regular expressions`_:
+
+    .. code-block:: jinja
+
+        {% if phone matches '/^[\\d\\.]+$/' %}
+        {% endif %}
+
+Containment Operator
+~~~~~~~~~~~~~~~~~~~~
+
+The ``in`` operator performs containment test.
+
+It returns ``true`` if the left operand is contained in the right:
+
+.. code-block:: jinja
+
+    {# returns true #}
+
+    {{ 1 in [1, 2, 3] }}
+
+    {{ 'cd' in 'abcde' }}
+
+.. tip::
+
+    You can use this filter to perform a containment test on strings, arrays,
+    or objects implementing the ``Traversable`` interface.
+
+To perform a negative test, use the ``not in`` operator:
+
+.. code-block:: jinja
+
+    {% if 1 not in [1, 2, 3] %}
+
+    {# is equivalent to #}
+    {% if not (1 in [1, 2, 3]) %}
+
+Test Operator
+~~~~~~~~~~~~~
+
+The ``is`` operator performs tests. Tests can be used to test a variable against
+a common expression. The right operand is name of the test:
+
+.. code-block:: jinja
+
+    {# find out if a variable is odd #}
+
+    {{ name is odd }}
+
+Tests can accept arguments too:
+
+.. code-block:: jinja
+
+    {% if post.status is constant('Post::PUBLISHED') %}
+
+Tests can be negated by using the ``is not`` operator:
+
+.. code-block:: jinja
+
+    {% if post.status is not constant('Post::PUBLISHED') %}
+
+    {# is equivalent to #}
+    {% if not (post.status is constant('Post::PUBLISHED')) %}
+
+Go to the :doc:`tests<tests/index>` page to learn more about the built-in
+tests.
+
+Other Operators
+~~~~~~~~~~~~~~~
+
+The following operators don't fit into any of the other categories:
+
+* ``|``: Applies a filter.
+
+* ``..``: Creates a sequence based on the operand before and after the operator
+  (this is just syntactic sugar for the :doc:`range<functions/range>` function):
+
+  .. code-block:: jinja
+
+      {{ 1..5 }}
+
+      {# equivalent to #}
+      {{ range(1, 5) }}
+
+  Note that you must use parentheses when combining it with the filter operator
+  due to the :ref:`operator precedence rules <twig-expressions>`:
+
+  .. code-block:: jinja
+
+      (1..5)|join(', ')
+
+* ``~``: Converts all operands into strings and concatenates them. ``{{ "Hello
+  " ~ name ~ "!" }}`` would return (assuming ``name`` is ``'John'``) ``Hello
+  John!``.
+
+* ``.``, ``[]``: Gets an attribute of an object.
+
+* ``?:``: The ternary operator:
+
+  .. code-block:: jinja
+
+      {{ foo ? 'yes' : 'no' }}
+      {{ foo ?: 'no' }} is the same as {{ foo ? foo : 'no' }}
+      {{ foo ? 'yes' }} is the same as {{ foo ? 'yes' : '' }}
+
+* ``??``: The null-coalescing operator:
+
+  .. code-block:: jinja
+
+      {# returns the value of foo if it is defined and not null, 'no' otherwise #}
+      {{ foo ?? 'no' }}
+
+String Interpolation
+~~~~~~~~~~~~~~~~~~~~
+
+String interpolation (``#{expression}``) allows any valid expression to appear
+within a *double-quoted string*. The result of evaluating that expression is
+inserted into the string:
+
+.. code-block:: jinja
+
+    {{ "foo #{bar} baz" }}
+    {{ "foo #{1 + 2} baz" }}
+
+.. _templates-whitespace-control:
+
+Whitespace Control
+------------------
+
+The first newline after a template tag is removed automatically (like in PHP.)
+Whitespace is not further modified by the template engine, so each whitespace
+(spaces, tabs, newlines etc.) is returned unchanged.
+
+Use the ``spaceless`` tag to remove whitespace *between HTML tags*:
+
+.. code-block:: jinja
+
+    {% spaceless %}
+        <div>
+            <strong>foo bar</strong>
+        </div>
+    {% endspaceless %}
+
+    {# output will be <div><strong>foo bar</strong></div> #}
+
+In addition to the spaceless tag you can also control whitespace on a per tag
+level. By using the whitespace control modifier on your tags, you can trim
+leading and or trailing whitespace:
+
+.. code-block:: jinja
+
+    {% set value = 'no spaces' %}
+    {#- No leading/trailing whitespace -#}
+    {%- if true -%}
+        {{- value -}}
+    {%- endif -%}
+
+    {# output 'no spaces' #}
+
+The above sample shows the default whitespace control modifier, and how you can
+use it to remove whitespace around tags. Trimming space will consume all whitespace
+for that side of the tag.  It is possible to use whitespace trimming on one side
+of a tag:
+
+.. code-block:: jinja
+
+    {% set value = 'no spaces' %}
+    <li>    {{- value }}    </li>
+
+    {# outputs '<li>no spaces    </li>' #}
+
+Extensions

+     *
+     *  * cache: An absolute path where to store the compiled templates,
+     *           a Twig_Cache_Interface implementation,

+     *  * strict_variables: Whether to ignore invalid variables in templates
+     *                      (default to false).

+     *                  * false: disable auto-escaping
+     *                  * html, js: set the autoescaping to one of the supported strategies

+     *                  * PHP callback: a PHP callback that returns an escaping strategy based on the template "name"

+ * To help debugging template issues, this class tracks the original template

+ * and/or the name is set to null). As this is a costly operation, this
+ * can be disabled by passing false for both the name and the line number
+ * when creating a new instance of this class.

+[![Dependency Status](https://www.versioneye.com/php/webmozart:assert/1.2.0/badge.svg)](https://www.versioneye.com/php/webmozart:assert/1.2.0)
+
+Latest release: [1.2.0](https://packagist.org/packages/webmozart/assert#1.2.0)
+
+PHP >= 5.3.9
+
+This library contains efficient assertions to test the input and output of
+your methods. With these assertions, you can greatly reduce the amount of coding
+needed to write a safe implementation.
+
+All assertions in the [`Assert`] class throw an `\InvalidArgumentException` if 
+they fail.
+
+FAQ
+---
+
+**What's the difference to [beberlei/assert]?**
+
+This library is heavily inspired by Benjamin Eberlei's wonderful [assert package],
+but fixes a usability issue with error messages that can't be fixed there without
+breaking backwards compatibility.
+
+This package features usable error messages by default. However, you can also 
+easily write custom error messages:
+
+```
+Assert::string($path, 'The path is expected to be a string. Got: %s');
+```
+
+In [beberlei/assert], the ordering of the `%s` placeholders is different for 
+every assertion. This package, on the contrary, provides consistent placeholder 
+ordering for all assertions:
+
+* `%s`: The tested value as string, e.g. `"/foo/bar"`.
+* `%2$s`, `%3$s`, ...: Additional assertion-specific values, e.g. the
+  minimum/maximum length, allowed values, etc.
+  
+Check the source code of the assertions to find out details about the additional
+available placeholders.
+
+Installation
+------------
+
+Use [Composer] to install the package:
+
+```
+$ composer require webmozart/assert
+```
+
+Example
+-------
+
+```php
+use Webmozart\Assert\Assert;
+
+class Employee
+{
+    public function __construct($id)
+    {
+        Assert::integer($id, 'The employee ID must be an integer. Got: %s');
+        Assert::greaterThan($id, 0, 'The employee ID must be a positive integer. Got: %s');
+    }
+}
+```
+
+If you create an employee with an invalid ID, an exception is thrown:
+
+```php
+new Employee('foobar');
+// => InvalidArgumentException: 
+//    The employee ID must be an integer. Got: string
+
+new Employee(-10);
+// => InvalidArgumentException: 
+//    The employee ID must be a positive integer. Got: -10
+```
+

+# Contributing
+
+Contributions are **welcome** and will be fully **credited**.
+
+We accept contributions via Pull Requests on [Github](https://github.com/wellingguzman/oauth2-okta).
+
+
+## Pull Requests
+
+- **[PSR-2 Coding Standard](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md)** - The easiest way to apply the conventions is to install [PHP Code Sniffer](http://pear.php.net/package/PHP_CodeSniffer).
+
+- **Add tests!** - Your patch won't be accepted if it doesn't have tests.
+
+- **Document any change in behaviour** - Make sure the README and any other relevant documentation are kept up-to-date.
+
+- **Consider our release cycle** - We try to follow SemVer. Randomly breaking public APIs is not an option.
+
+- **Create topic branches** - Don't ask us to pull from your master branch.
+
+- **One pull request per feature** - If you want to do more than one thing, send multiple pull requests.
+
+- **Send coherent history** - Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please squash them before submitting.
+
+- **Ensure tests pass!** - Please run the tests (see below) before submitting your pull request, and make sure they pass. We won't accept a patch until all tests pass.
+
+- **Ensure no coding standards violations** - Please run PHP Code Sniffer using the PSR-2 standard (see below) before submitting your pull request. A violation will cause the build to fail, so please make sure there are no violations. We can't accept a patch if the build fails.
+
+
+## Running Tests
+
+``` bash
+$ ./vendor/bin/phpunit
+```
+
+
+## Running PHP Code Sniffer
+
+``` bash
+$ ./vendor/bin/phpcs src --standard=psr2 -sp
+```
+
+**Happy coding**!

+
+This package provides Okta OAuth 2.0 support for the PHP League's [OAuth 2.0 Client](https://github.com/thephpleague/oauth2-client).
+
+## Installation
+
+To install, use composer:
+
+```
+composer require wellingguzman/oauth2-okta
+```
+
+## Usage
+
+Usage is the same as The League's OAuth client, using `\WellingGuzman\OAuth2\Client\Provider\Okta` as the provider.
+
+### Authorization Code Flow
+
+```php
+$provider = new WellingGuzman\OAuth2\Client\Provider\Okta([
+    'baseUrl'           => '{base-url}',
+    'clientId'          => '{okta-client-id}',
+    'clientSecret'      => '{okta-client-secret}',
+    'redirectUri'       => 'https://example.com/callback-url',
+]);
+
+if (!isset($_GET['code'])) {
+
+    // If we don't have an authorization code then get one
+    $authUrl = $provider->getAuthorizationUrl();
+    $_SESSION['oauth2state'] = $provider->getState();
+    header('Location: '.$authUrl);
+    exit;
+
+// Check given state against previously stored one to mitigate CSRF attack
+} elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {
+
+    unset($_SESSION['oauth2state']);
+    exit('Invalid state');
+
+} else {
+
+    // Try to get an access token (using the authorization code grant)
+    $token = $provider->getAccessToken('authorization_code', [
+        'code' => $_GET['code']
+    ]);
+
+    // Optional: Now you have a token you can look up a users profile data
+    try {
+
+        // We got an access token, let's now get the user's details
+        $user = $provider->getResourceOwner($token);
+
+        // Use these details to create a new profile
+        printf('Hello %s!', $user->getNickname());
+
+    } catch (Exception $e) {
+
+        // Failed to get user details
+        exit('Oh dear...');
+    }
+
+    // Use this to interact with an API on the users behalf
+    echo $token->getToken();
+}
+```
+
+### Managing Scopes
+
+When creating your Okta authorization URL, you can specify the state and scopes your application may authorize.
+
+```php
+$options = [
+    'state' => 'OPTIONAL_CUSTOM_CONFIGURED_STATE',
+    'scope' => ['openid email profile']
+];
+
+$authorizationUrl = $provider->getAuthorizationUrl($options);
+```
+If neither are defined, the provider will utilize internal defaults.
+
+At the time of authoring this documentation, the [following scopes are available](https://developer.okta.com/standards/OIDC/#scopes).
+
+- openid
+- profile
+- email
+- phone
+- address
+- groups
+
+## Testing
+
+``` bash
+$ ./vendor/bin/phpunit
+```

+# Rate Limit
+
+[![Build Status](https://travis-ci.org/wellingguzman/rate-limit.svg?branch=master)](https://travis-ci.org/wellingguzman/rate-limit)
+[![Scrutinizer Code Quality](https://scrutinizer-ci.com/g/wellingguzman/rate-limit/badges/quality-score.png?b=master)](https://scrutinizer-ci.com/g/wellingguzman/rate-limit/?branch=master)
+[![Code Coverage](https://scrutinizer-ci.com/g/wellingguzman/wellingguzman/badges/coverage.png?b=master)](https://scrutinizer-ci.com/g/wellingguzman/rate-limit/?branch=master)
+[![Latest Stable Version](https://poser.pugx.org/wellingguzman/rate-limit/v/stable)](https://packagist.org/packages/wellingguzman/rate-limit)
+
+Component that facilitates rate-limiting functionality. Although designed as a standalone, it also provides a middleware designed for API and/or other application endpoints that be used with any framework that supports the middleware concept.
+
+Based on `nikolaposa/rate-limit`. Type-hinting and `declare` function were removed to support PHP 5.6.
+
+## Installation
+
+The preferred method of installation is via [Composer](http://getcomposer.org/). Run the following
+command to install the latest version of a package and add it to your project's `composer.json`:
+
+```bash
+composer require wellingguzman/rate-limit
+```
+
+## Usage
+
+### Standalone
+
+```php
+$rateLimiter = \RateLimit\RateLimiterFactory::createInMemoryRateLimiter(1000, 3600);
+
+echo $rateLimiter->getLimit(); //1000
+echo $rateLimiter->getWindow(); //3600
+
+$rateLimiter->hit('key');
+
+echo $rateLimiter->getRemainingAttempts('key'); //999
+echo $rateLimiter->getResetAt('key'); //1486503558
+```
+
+**Note**: in-memory rate limiter should only be used for testing purposes. This package also provides Redis-backed rate limiter:
+
+```php
+$rateLimiter = \RateLimit\RateLimiterFactory::createRedisBackedRateLimiter([
+    'host' => '10.0.0.7',
+    'port' => 6379,
+], 1000, 3600);
+```
+
+### Middleware
+
+Zend Expressive example:
+
+```php
+$app = \Zend\Expressive\AppFactory::create();
+
+$app->pipe(\RateLimit\Middleware\RateLimitMiddleware::createDefault(
+   \RateLimit\RateLimiterFactory::createRedisBackedRateLimiter([
+       'host' => '10.0.0.7',
+       'port' => 6379,
+   ], 1000, 3600)
+));
+```
+
+Slim example:
+
+```php
+$app = new \Slim\App();
+
+$app->add(\RateLimit\Middleware\RateLimitMiddleware::createDefault(
+    \RateLimit\RateLimiterFactory::createRedisBackedRateLimiter([
+       'host' => '10.0.0.7',
+       'port' => 6379,
+   ], 1000, 3600)
+));
+```
+
+Whitelisting requests:
+
+```php
+use Psr\Http\Message\RequestInterface;
+
+$rateLimitMiddleware = \RateLimit\Middleware\RateLimitMiddleware::createDefault(
+   \RateLimit\RateLimiterFactory::createRedisBackedRateLimiter([
+        'host' => '10.0.0.7',
+        'port' => 6379,
+    ], 1000, 3600),
+    [
+        'whitelist' => function (RequestInterface $request) {
+           if (false !== strpos($request->getUri()->getPath(), 'admin')) {
+               return true;
+           }
+         
+           return false;
+        },
+    ]
+);
+```
+
+Custom limit exceeded handler:
+
+```php
+use Psr\Http\Message\RequestInterface;
+use Zend\Diactoros\Response\JsonResponse;
+
+$rateLimitMiddleware = \RateLimit\Middleware\RateLimitMiddleware::createDefault(
+    \RateLimit\RateLimiterFactory::createRedisBackedRateLimiter([
+        'host' => '10.0.0.7',
+        'port' => 6379,
+    ], 1000, 3600),
+    [
+        'limitExceededHandler' => function (RequestInterface $request) {
+           return new JsonResponse([
+               'message' => 'API rate limit exceeded',
+           ], 429);
+        },
+    ]
+);
+```

+# Changelog
+
+All notable changes to this project will be documented in this file, in reverse chronological order by release.
+
+## 2.9.3 - TBD
+
+### Added
+
+- Nothing.
+
+### Changed
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed

+
+## 2.9.2 - 2017-12-11
+
+### Added
+
+- Nothing.
+
+### Changed
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- [#292](https://github.com/zendframework/zend-db/pull/292) ensures that you may
+  reference bound parameter names using a leading colon (`:`) character when
+  using the PDO adapter. (The leading colon is not technically necessary, as the
+  adapter will prefix for you; however, this ensures portability with vanilla
+  PDO.)
+
+## 2.9.1 - 2017-12-07
+
+### Added
+
+- Nothing.
+
+### Changed
+
+- [#289](https://github.com/zendframework/zend-db/pull/289) reverts a change
+  introduced in 2.9.0 and modifies the behavior of the PDO adapter slightly
+  to remove a regression. In 2.9.0, when binding parameters with names that
+  contained characters not supported by PDO, we would pass the parameter names
+  to `md5()`; this caused a regression, as the SQL string containing the
+  parameter name was not also updated.
+
+  This patch modifies the behavior during a bind-operation to instead raise an
+  exception if a parameter name contains characters not supported by PDO.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Nothing.
+
+## 2.9.0 - 2017-12-06
+
+### Added
+
+- [#216](https://github.com/zendframework/zend-db/pull/216) added AFTER support
+  in ALTER TABLE syntax for MySQL
+- [#223](https://github.com/zendframework/zend-db/pull/223) added support for
+  empty values set with IN predicate
+- [#271](https://github.com/zendframework/zend-db/pull/271) added support for
+  dash character on MySQL identifier
+- [#273](https://github.com/zendframework/zend-db/pull/273) added support for
+  implementing an error handler for db2_prepare
+- [#275](https://github.com/zendframework/zend-db/pull/275) added support for
+  LIMIT OFFSET for db2
+- [#280](https://github.com/zendframework/zend-db/pull/280) added version dsn
+  parameter for pdo_dblib
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- [#205](https://github.com/zendframework/zend-db/pull/205) fixes the spaces in
+  ORDER BY syntax
+- [#224](https://github.com/zendframework/zend-db/pull/224) fixes how parameters
+  are bound to statements in the PDO adapter. PDO has a restriction on parameter
+  names of `[0-9a-zA_Z_]`; as such, the driver now hashes the parameter names
+  using `md5()` in order to ensure compatibility with other drivers.
+- [#229](https://github.com/zendframework/zend-db/pull/229) fixes the support
+  of SSL for mysqli
+- [#255](https://github.com/zendframework/zend-db/pull/255) fixes ResultSet with
+  array values
+- [#261](https://github.com/zendframework/zend-db/pull/261) fixes Exception in
+  Firebird driver doesn't support lastInsertId
+- [#276](https://github.com/zendframework/zend-db/pull/276) fixes the support
+  of PHP 7.2
+- [#287](https://github.com/zendframework/zend-db/pull/287) fixes the usage of
+  count() with PHP 7.2
+
+## 2.8.2 - 2016-08-09

+
+- Nothing.
+
+### Fixed
+
+- [#154](https://github.com/zendframework/zend-db/pull/154) fixes the how the

+  statement is generated.
+- [#112](https://github.com/zendframework/zend-db/pull/112) fixes the test on
+  the number of replacements when using the same variable name.
+- [#115](https://github.com/zendframework/zend-db/pull/115) TableGateway update
+  method was incorrect when specifying default join declaration.
+- [#145](https://github.com/zendframework/zend-db/pull/145) Fix MSSQL Select
+  when encounting DISTINCT and OFFSET and LIMIT together.
+- [#153](https://github.com/zendframework/zend-db/pull/153) Runtime exception
+  threw fatal error due to incorrect spelling of the class when a DSN did not
+  exist.

+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+

+  behavior to re-allow selecting an empty column set from the joined table.
+- [#106](https://github.com/zendframework/zend-db/pull/106) fixes an issue in
+  the test suite when ext/pgsql is enabled, but no databases are avaiable.
+
+## 2.8.0 - 2016-04-12
+
+### Added
+
+- [#92](https://github.com/zendframework/zend-db/pull/92) adds the class
+  `Zend\Db\Sql\Join` for creating and aggregating JOIN specifications. This is
+  now consumed by all `Zend\Db\Sql` implementations in order to represent JOIN
+  statements.
+- [#92](https://github.com/zendframework/zend-db/pull/92) adds support for JOIN
+  operations to UPDATE statements.
+- [#92](https://github.com/zendframework/zend-db/pull/92) adds support for joins
+  to `AbstractTableGateway::update`; you can now pass an array of
+  specifications via a third argument to the method.
+- [#96](https://github.com/zendframework/zend-db/pull/96) exposes the package as
+  config-provider/component, but adding:
+  - `Zend\Db\ConfigProvider`, which maps the `AdapterInterface` to the
+    `AdapterServiceFactory`, and enables the `AdapterAbstractServiceFactory`.
+  - `Zend\Db\Module`, which does the same, for a zend-mvc context.
+

+
+- Nothing.
+
+### Fixed
+
+- [#71](https://github.com/zendframework/zend-db/pull/71) updates the `Pgsql`
+  adapter to allow passing the connection charset; this can be done with the
+  `charset` option when creating your adapter.
+- [#76](https://github.com/zendframework/zend-db/pull/76) fixes the behavior of
+  `Zend\Db\Sql\Insert` when an array of names is used for columns to ensure the
+  string names are used, and not the array indices.
+- [#91](https://github.com/zendframework/zend-db/pull/91) fixes the behavior of
+  the `Oci8` adapter when initializing a result set; previously, it was
+  improperly assigning the count of affected rows to the generated value.
+- [#95](https://github.com/zendframework/zend-db/pull/95) fixes the `IbmDb2`
+  platform's `quoteIdentifier()` method to properly allow `#` characters in
+  identifiers (as they are commonly used on that platform).

+
+### Added
+
+- [#42](https://github.com/zendframework/zend-db/pull/42) updates the component

+  compatibility with zend-hydrator, and backwards compatibility with
+  hydrators from older versions of zend-stdlib.
+- [#15](https://github.com/zendframework/zend-db/pull/15) adds a new predicate,
+  `Zend\Db\Sql\Predicate\NotBetween`, which can be invoked via `Sql`

+- [#22](https://github.com/zendframework/zend-db/pull/22) extracts a factory,
+  `Zend\Db\Metadata\Source\Factory`, from `Zend\Db\Metadata\Metadata`,
+  removing the (non-public) `createSourceFromAdapter()` method from that

+
+### Removed
+
+- [#29](https://github.com/zendframework/zend-db/pull/29) removes the required
+  second argument to `Zend\Db\Predicate\Predicate::expression()`, allowing it to
+  be nullable, and mirroring the constructor of `Zend\Db\Predicate\Expression`.
+
+### Fixed
+
+- [#40](https://github.com/zendframework/zend-db/pull/40) updates the
+  zend-stdlib dependency to reference `>=2.5.0,<2.7.0` to ensure hydrators
+  will work as expected following extraction of hydrators to the zend-hydrator
+  repository.
+- [#34](https://github.com/zendframework/zend-db/pull/34) fixes retrieval of
+  constraint metadata in the Oracle adapter.
+- [#41](https://github.com/zendframework/zend-db/pull/41) removes hard dependency
+  on EventManager in AbstractTableGateway.
+- [#17](https://github.com/zendframework/zend-db/pull/17) removes an executable
+  bit on a regular file.

+  closure binding (now that we're on 5.5+, this is possible).
+- [#9](https://github.com/zendframework/zend-db/pull/9) thoroughly audits the
+  OCI8 (Oracle) driver, ensuring it provides feature parity with other drivers,
+  and fixes issues with subselects, limits, and offsets.

+# Contributor Code of Conduct
+
+This project adheres to [The Code Manifesto](http://codemanifesto.com)
+as its guidelines for contributor interactions.
+
+## The Code Manifesto
+
+We want to work in an ecosystem that empowers developers to reach their
+potential — one that encourages growth and effective collaboration. A space that
+is safe for all.
+
+A space such as this benefits everyone that participates in it. It encourages
+new developers to enter our field. It is through discussion and collaboration
+that we grow, and through growth that we improve.
+
+In the effort to create such a place, we hold to these values:
+
+1. **Discrimination limits us.** This includes discrimination on the basis of
+   race, gender, sexual orientation, gender identity, age, nationality, technology
+   and any other arbitrary exclusion of a group of people.
+2. **Boundaries honor us.** Your comfort levels are not everyone’s comfort
+   levels. Remember that, and if brought to your attention, heed it.
+3. **We are our biggest assets.** None of us were born masters of our trade.
+   Each of us has been helped along the way. Return that favor, when and where
+   you can.
+4. **We are resources for the future.** As an extension of #3, share what you
+   know. Make yourself a resource to help those that come after you.
+5. **Respect defines us.** Treat others as you wish to be treated. Make your
+   discussions, criticisms and debates from a position of respectfulness. Ask
+   yourself, is it true? Is it necessary? Is it constructive? Anything less is
+   unacceptable.
+6. **Reactions require grace.** Angry responses are valid, but abusive language
+   and vindictive actions are toxic. When something happens that offends you,
+   handle it assertively, but be respectful. Escalate reasonably, and try to
+   allow the offender an opportunity to explain themselves, and possibly correct
+   the issue.

+
+## RUNNING TESTS
+
+To run tests:
+
+- Clone the repository:
+
+  ```console
+  $ git clone git://github.com/zendframework/zend-db.git
+  $ cd zend-db
+  ```
+
+- Install dependencies via composer:
+
+  ```console
+  $ composer install
+  ```
+
+  If you don't have `composer` installed, please download it from https://getcomposer.org/download/
+
+- Run the tests using the "test" command shipped in the `composer.json`:
+
+  ```console
+  $ composer test
+  ```
+
+You can turn on conditional tests with the `phpunit.xml` file.
+To do so:
+
+ -  Copy `phpunit.xml.dist` file to `phpunit.xml`
+ -  Edit `phpunit.xml` to enable any specific functionality you
+    want to test, as well as to provide test values to utilize.
+
+## Running Coding Standards Checks
+
+First, ensure you've installed dependencies via composer, per the previous
+section on running tests.
+
+To run CS checks only:
+
+```console
+$ composer cs-check
+```
+
+To attempt to automatically fix common CS issues:
+
+```console
+$ composer cs-fix
+```
+
+If the above fixes any CS issues, please re-run the tests to ensure
+they pass, and make sure you add and commit the changes after verification.
+
+## Recommended Workflow for Contributions
+
+Your first step is to establish a public repository from which we can
+pull your work into the master repository. We recommend using
+[GitHub](https://github.com), as that is where the component is already hosted.
+
+1. Setup a [GitHub account](https://github.com/), if you haven't yet
+2. Fork the repository (https://github.com/zendframework/zend-db)
+3. Clone the canonical repository locally and enter it.
+
+   ```console
+   $ git clone git://github.com/zendframework/zend-db.git
+   $ cd zend-db
+   ```
+
+4. Add a remote to your fork; substitute your GitHub username in the command
+   below.
+
+   ```console
+   $ git remote add {username} git@github.com:{username}/zend-db.git
+   $ git fetch {username}
+   ```
+
+### Keeping Up-to-Date
+
+Periodically, you should update your fork or personal repository to
+match the canonical ZF repository. Assuming you have setup your local repository
+per the instructions above, you can do the following:
+
+
+```console
+$ git checkout master
+$ git fetch origin
+$ git rebase origin/master
+# OPTIONALLY, to keep your remote up-to-date -
+$ git push {username} master:master
+```
+
+If you're tracking other branches -- for example, the "develop" branch, where
+new feature development occurs -- you'll want to do the same operations for that
+branch; simply substitute  "develop" for "master".
+
+### Working on a patch
+
+We recommend you do each new feature or bugfix in a new branch. This simplifies
+the task of code review as well as the task of merging your changes into the
+canonical repository.
+
+A typical workflow will then consist of the following:
+
+1. Create a new local branch based off either your master or develop branch.
+2. Switch to your new local branch. (This step can be combined with the
+   previous step with the use of `git checkout -b`.)
+3. Do some work, commit, repeat as necessary.
+4. Push the local branch to your remote repository.
+5. Send a pull request.
+
+The mechanics of this process are actually quite trivial. Below, we will
+create a branch for fixing an issue in the tracker.
+
+```console
+$ git checkout -b hotfix/9295
+Switched to a new branch 'hotfix/9295'
+```
+
+... do some work ...
+
+
+```console
+$ git commit
+```
+
+... write your log message ...
+
+
+```console
+$ git push {username} hotfix/9295:hotfix/9295
+Counting objects: 38, done.
+Delta compression using up to 2 threads.
+Compression objects: 100% (18/18), done.
+Writing objects: 100% (20/20), 8.19KiB, done.
+Total 20 (delta 12), reused 0 (delta 0)
+To ssh://git@github.com/{username}/zend-db.git
+   b5583aa..4f51698  HEAD -> master
+```
+
+To send a pull request, you have two options.
+
+If using GitHub, you can do the pull request from there. Navigate to
+your repository, select the branch you just created, and then select the
+"Pull Request" button in the upper right. Select the user/organization
+"zendframework" (or whatever the upstream organization is) as the recipient.
+
+#### What branch to issue the pull request against?
+
+Which branch should you issue a pull request against?
+
+- For fixes against the stable release, issue the pull request against the
+  "master" branch.
+- For new features, or fixes that introduce new elements to the public API (such
+  as new public methods or properties), issue the pull request against the
+  "develop" branch.
+
+### Branch Cleanup
+
+As you might imagine, if you are a frequent contributor, you'll start to
+get a ton of branches both locally and on your remote.
+
+Once you know that your changes have been accepted to the master
+repository, we suggest doing some cleanup of these branches.
+
+-  Local branch cleanup
+
+   ```console
+   $ git branch -d <branchname>
+   ```
+
+-  Remote branch removal
+
+   ```console
+   $ git push {username} :<branchname>
+   ```

+# Adapters
+
+`Zend\Db\Adapter\Adapter` is the central object of the zend-db component. It is
+responsible for adapting any code written in or for zend-db to the targeted PHP
+extensions and vendor databases. In doing this, it creates an abstraction layer
+for the PHP extensions in the `Driver` subnamespace of `Zend\Db\Adapter`.  It
+also creates a lightweight "Platform" abstraction layer, for the various
+idiosyncrasies that each vendor-specific platform might have in its SQL/RDBMS
+implementation, separate from the driver implementations.
+
+## Creating an adapter using configuration
+
+Create an adapter by instantiating the `Zend\Db\Adapter\Adapter` class. The most
+common use case, while not the most explicit, is to pass an array of
+configuration to the `Adapter`:
+
+```php
+use Zend\Db\Adapter\Adapter;
+
+$adapter = new Adapter($configArray);
+```
+
+This driver array is an abstraction for the extension level required parameters.
+Here is a table for the key-value pairs that should be in configuration array.
+
+Key        | Is Required?           | Value
+---------- | ---------------------- | -----
+`driver`   | required               | `Mysqli`, `Sqlsrv`, `Pdo_Sqlite`, `Pdo_Mysql`, `Pdo`(= Other PDO Driver)
+`database` | generally required     | the name of the database (schema)
+`username` | generally required     | the connection username
+`password` | generally required     | the connection password
+`hostname` | not generally required | the IP address or hostname to connect to
+`port`     | not generally required | the port to connect to (if applicable)
+`charset`  | not generally required | the character set to use
+
+> ### Options are adapter-dependent
+>
+> Other names will work as well. Effectively, if the PHP manual uses a
+> particular naming, this naming will be supported by the associated driver. For
+> example, `dbname` in most cases will also work for 'database'.  Another
+> example is that in the case of `Sqlsrv`, `UID` will work in place of
+> `username`. Which format you choose is up to you, but the above table
+> represents the official abstraction names.
+
+For example, a MySQL connection using ext/mysqli:
+
+```php
+$adapter = new Zend\Db\Adapter\Adapter([
+    'driver'   => 'Mysqli',
+    'database' => 'zend_db_example',
+    'username' => 'developer',
+    'password' => 'developer-password',
+]);
+```
+
+Another example, of a Sqlite connection via PDO:
+
+```php
+$adapter = new Zend\Db\Adapter\Adapter([
+    'driver'   => 'Pdo_Sqlite',
+    'database' => 'path/to/sqlite.db',
+]);
+```
+
+Another example, of an IBM i DB2 connection via IbmDb2:
+
+```php
+$adapter = new Zend\Db\Adapter\Adapter([
+    'database' => '*LOCAL', // or name from WRKRDBDIRE, may be serial #
+    'driver' => 'IbmDb2',
+    'driver_options' => [
+        'autocommit' => DB2_AUTOCOMMIT_ON,
+        'i5_naming' => DB2_I5_NAMING_ON,
+        'i5_libl' => 'SCHEMA1 SCHEMA2 SCHEMA3',
+    ],
+    'username' => '__USER__',
+    'password' => '__PASS__',
+    // 'persistent' => true,
+    'platform' => 'IbmDb2',
+    'platform_options' => ['quote_identifiers' => false],
+]);
+```
+
+Another example, of an IBM i DB2 connection via PDO:
+
+```php
+$adapter = new Zend\Db\Adapter\Adapter([
+    'dsn' => 'ibm:DB_NAME', // DB_NAME is from WRKRDBDIRE, may be serial #
+    'driver' => 'pdo',
+    'driver_options' => [
+        // PDO::ATTR_PERSISTENT => true,
+        PDO::ATTR_AUTOCOMMIT => true,
+        PDO::I5_ATTR_DBC_SYS_NAMING => true,
+        PDO::I5_ATTR_DBC_CURLIB => '',
+        PDO::I5_ATTR_DBC_LIBL => 'SCHEMA1 SCHEMA2 SCHEMA3',
+    ],
+    'username' => '__USER__',
+    'password' => '__PASS__',
+    'platform' => 'IbmDb2',
+    'platform_options' => ['quote_identifiers' => false],
+]);
+```
+
+It is important to know that by using this style of adapter creation, the
+`Adapter` will attempt to create any dependencies that were not explicitly
+provided. A `Driver` object will be created from the configuration array
+provided in the constructor. A `Platform` object will be created based off the
+type of `Driver` class that was instantiated. And lastly, a default `ResultSet`
+object is created and utilized. Any of these objects can be injected, to do
+this, see the next section.
+
+The list of officially supported drivers:
+
+- `IbmDb2`: The ext/ibm_db2 driver
+- `Mysqli`: The ext/mysqli driver
+- `Oci8`: The ext/oci8 driver
+- `Pgsql`: The ext/pgsql driver
+- `Sqlsrv`: The ext/sqlsrv driver (from Microsoft)
+- `Pdo_Mysql`: MySQL via the PDO extension
+- `Pdo_Sqlite`: SQLite via the PDO extension
+- `Pdo_Pgsql`: PostgreSQL via the PDO extension
+
+## Creating an adapter using dependency injection
+
+The more expressive and explicit way of creating an adapter is by injecting all
+your dependencies up front. `Zend\Db\Adapter\Adapter` uses constructor
+injection, and all required dependencies are injected through the constructor,
+which has the following signature (in pseudo-code):
+
+```php
+use Zend\Db\Adapter\Platform\PlatformInterface;
+use Zend\Db\ResultSet\ResultSet;
+
+class Zend\Db\Adapter\Adapter
+{
+    public function __construct(
+        $driver,
+        PlatformInterface $platform = null,
+        ResultSet $queryResultSetPrototype = null
+    );
+}
+```
+
+What can be injected:
+
+- `$driver`: an array of connection parameters (see above) or an instance of
+  `Zend\Db\Adapter\Driver\DriverInterface`.
+- `$platform` (optional): an instance of `Zend\Db\Platform\PlatformInterface`;
+  the default will be created based off the driver implementation.
+- `$queryResultSetPrototype` (optional): an instance of
+  `Zend\Db\ResultSet\ResultSet`; to understand this object's role, see the
+  section below on querying.
+
+## Query Preparation
+
+By default, `Zend\Db\Adapter\Adapter::query()` prefers that you use
+"preparation" as a means for processing SQL statements.  This generally means
+that you will supply a SQL statement containing placeholders for the values, and
+separately provide substitutions for those placeholders. As an example:
+
+```php
+$adapter->query('SELECT * FROM `artist` WHERE `id` = ?', [5]);
+```
+
+The above example will go through the following steps:
+
+- create a new `Statement` object.
+- prepare the array `[5]` into a `ParameterContainer` if necessary.
+- inject the `ParameterContainer` into the `Statement` object.
+- execute the `Statement` object, producing a `Result` object.
+- check the `Result` object to check if the supplied SQL was a result set
+  producing statement:
+    - if the query produced a result set, clone the `ResultSet` prototype,
+      inject the `Result` as its datasource, and return the new `ResultSet`
+      instance.
+    - otherwise, return the `Result`.
+
+## Query Execution
+
+In some cases, you have to execute statements directly without preparation. One
+possible reason for doing so would be to execute a DDL statement, as most
+extensions and RDBMS systems are incapable of preparing such statements.
+
+To execute a query without the preparation step, you will need to pass a flag as
+the second argument indicating execution is required:
+
+```php
+$adapter->query(
+    'ALTER TABLE ADD INDEX(`foo_index`) ON (`foo_column`)',
+    Adapter::QUERY_MODE_EXECUTE
+);
+```
+
+The primary difference to notice is that you must provide the
+`Adapter::QUERY_MODE_EXECUTE` (execute) flag as the second parameter.
+
+## Creating Statements
+
+While `query()` is highly useful for one-off and quick querying of a database
+via the `Adapter`, it generally makes more sense to create a statement and
+interact with it directly, so that you have greater control over the
+prepare-then-execute workflow. To do this, `Adapter` gives you a routine called
+`createStatement()` that allows you to create a `Driver` specific `Statement` to
+use so you can manage your own prepare-then-execute workflow.
+
+```php
+// with optional parameters to bind up-front:
+$statement = $adapter->createStatement($sql, $optionalParameters);
+$result    = $statement->execute();
+```
+
+## Using the Driver Object
+
+The `Driver` object is the primary place where `Zend\Db\Adapter\Adapter`
+implements the connection level abstraction specific to a given extension.  To
+make this possible, each driver is composed of 3 objects:
+
+- A connection: `Zend\Db\Adapter\Driver\ConnectionInterface`
+- A statement: `Zend\Db\Adapter\Driver\StatementInterface`
+- A result: `Zend\Db\Adapter\Driver\ResultInterface`
+
+Each of the built-in drivers practice "prototyping" as a means of creating
+objects when new instances are requested. The workflow looks like this:
+
+- An adapter is created with a set of connection parameters.
+- The adapter chooses the proper driver to instantiate (for example,
+  `Zend\Db\Adapter\Driver\Mysqli`)
+- That driver class is instantiated.
+- If no connection, statement, or result objects are injected, defaults are
+  instantiated.
+
+This driver is now ready to be called on when particular workflows are
+requested. Here is what the `Driver` API looks like:
+
+```php
+namespace Zend\Db\Adapter\Driver;
+
+interface DriverInterface
+{
+    const PARAMETERIZATION_POSITIONAL = 'positional';
+    const PARAMETERIZATION_NAMED = 'named';
+    const NAME_FORMAT_CAMELCASE = 'camelCase';
+    const NAME_FORMAT_NATURAL = 'natural';
+
+    public function getDatabasePlatformName(string $nameFormat = self::NAME_FORMAT_CAMELCASE) : string;
+    public function checkEnvironment() : bool;
+    public function getConnection() : ConnectionInterface;
+    public function createStatement(string|resource $sqlOrResource = null) : StatementInterface;
+    public function createResult(resource $resource) : ResultInterface;
+    public function getPrepareType() :string;
+    public function formatParameterName(string $name, $type = null) : string;
+    public function getLastGeneratedValue() : mixed;
+}
+```
+
+From this `DriverInterface`, you can
+
+- Determine the name of the platform this driver supports (useful for choosing
+  the proper platform object).
+- Check that the environment can support this driver.
+- Return the `Connection` instance.
+- Create a `Statement` instance which is optionally seeded by an SQL statement
+  (this will generally be a clone of a prototypical statement object).
+- Create a `Result` object which is optionally seeded by a statement resource
+  (this will generally be a clone of a prototypical result object)
+- Format parameter names; this is important to distinguish the difference
+  between the various ways parameters are named between extensions
+- Retrieve the overall last generated value (such as an auto-increment value).
+
+Now let's turn to the `Statement` API:
+
+```php
+namespace Zend\Db\Adapter\Driver;
+
+interface StatementInterface extends StatementContainerInterface
+{
+    public function getResource() : resource;
+    public function prepare($sql = null) : void;
+    public function isPrepared() : bool;
+    public function execute(null|array|ParameterContainer $parameters = null) : ResultInterface;
+
+    /** Inherited from StatementContainerInterface */
+    public function setSql(string $sql) : void;
+    public function getSql() : string;
+    public function setParameterContainer(ParameterContainer $parameterContainer) : void;
+    public function getParameterContainer() : ParameterContainer;
+}
+```
+
+And finally, the `Result` API:
+
+```php
+namespace Zend\Db\Adapter\Driver;
+
+use Countable;
+use Iterator;
+
+interface ResultInterface extends Countable, Iterator
+{
+    public function buffer() : void;
+    public function isQueryResult() : bool;
+    public function getAffectedRows() : int;
+    public function getGeneratedValue() : mixed;
+    public function getResource() : resource;
+    public function getFieldCount() : int;
+}
+```
+
+## Using The Platform Object
+
+The `Platform` object provides an API to assist in crafting queries in a way
+that is specific to the SQL implementation of a particular vendor. The object
+handles nuances such as how identifiers or values are quoted, or what the
+identifier separator character is. To get an idea of the capabilities, the
+interface for a platform object looks like this:
+
+```php
+namespace Zend\Db\Adapter\Platform;
+
+interface PlatformInterface
+{
+    public function getName() : string;
+    public function getQuoteIdentifierSymbol() : string;
+    public function quoteIdentifier(string $identifier) : string;
+    public function quoteIdentifierChain(string|string[] $identiferChain) : string;
+    public function getQuoteValueSymbol() : string;
+    public function quoteValue(string $value) : string;
+    public function quoteTrustedValue(string $value) : string;
+    public function quoteValueList(string|string[] $valueList) : string;
+    public function getIdentifierSeparator() : string;
+    public function quoteIdentifierInFragment(string $identifier, array $additionalSafeWords = []) : string;
+}
+```
+
+While you can directly instantiate a `Platform` object, generally speaking, it
+is easier to get the proper `Platform` instance from the configured adapter (by
+default the `Platform` type will match the underlying driver implementation):
+
+```php
+$platform = $adapter->getPlatform();
+
+// or
+$platform = $adapter->platform; // magic property access
+```
+
+The following are examples of `Platform` usage:
+
+```php
+// $adapter is a Zend\Db\Adapter\Adapter instance;
+// $platform is a Zend\Db\Adapter\Platform\Sql92 instance.
+$platform = $adapter->getPlatform();
+
+// "first_name"
+echo $platform->quoteIdentifier('first_name');
+
+// "
+echo $platform->getQuoteIdentifierSymbol();
+
+// "schema"."mytable"
+echo $platform->quoteIdentifierChain(['schema', 'mytable']);
+
+// '
+echo $platform->getQuoteValueSymbol();
+
+// 'myvalue'
+echo $platform->quoteValue('myvalue');
+
+// 'value', 'Foo O\\'Bar'
+echo $platform->quoteValueList(['value', "Foo O'Bar"]);
+
+// .
+echo $platform->getIdentifierSeparator();
+
+// "foo" as "bar"
+echo $platform->quoteIdentifierInFragment('foo as bar');
+
+// additionally, with some safe words:
+// ("foo"."bar" = "boo"."baz")
+echo $platform->quoteIdentifierInFragment('(foo.bar = boo.baz)', ['(', ')', '=']);
+```
+
+## Using The Parameter Container
+
+The `ParameterContainer` object is a container for the various parameters that
+need to be passed into a `Statement` object to fulfill all the various
+parameterized parts of the SQL statement. This object implements the
+`ArrayAccess` interface. Below is the `ParameterContainer` API:
+
+```php
+namespace Zend\Db\Adapter;
+
+use ArrayAccess;
+use ArrayIterator;
+use Countable;
+use Iterator;
+
+class ParameterContainer implements Iterator, ArrayAccess, Countable
+{
+    public function __construct(array $data = [])

+    public function setFromArray(array $data) : ParameterContainer;

+    public function offsetGetErrata(string|int $name) : mixed;
+    public function offsetHasErrata(string|int $name) : bool;
+    public function offsetUnsetErrata(string|int $name) : void;
+
+    /** errata only iterator */
+    public function getErrataIterator() : ArrayIterator;
+
+    /** get array with named keys */
+    public function getNamedArray() : array;
+
+    /** get array with int keys, ordered by position */
+    public function getPositionalArray() : array;
+
+    /** iterator: */
+    public function count() : int;
+    public function current() : mixed;
+    public function next() : mixed;
+    public function key() : string|int;
+    public function valid() : bool;
+    public function rewind() : void;
+
+    /** merge existing array of parameters with existing parameters */
+    public function merge(array $parameters) : ParameterContainer;
+}
+```
+
+In addition to handling parameter names and values, the container will assist in
+tracking parameter types for PHP type to SQL type handling. For example, it
+might be important that:
+
+```php
+$container->offsetSet('limit', 5);
+```
+
+be bound as an integer. To achieve this, pass in the
+`ParameterContainer::TYPE_INTEGER` constant as the 3rd parameter:
+
+```php
+$container->offsetSet('limit', 5, $container::TYPE_INTEGER);
+```
+
+This will ensure that if the underlying driver supports typing of bound
+parameters, that this translated information will also be passed along to the
+actual php database driver.
+
+## Examples
+
+Creating a `Driver`, a vendor-portable query, and preparing and iterating the
+result:
+
+```php
+$adapter = new Zend\Db\Adapter\Adapter($driverConfig);
+
+$qi = function ($name) use ($adapter) {
+    return $adapter->platform->quoteIdentifier($name);
+};
+$fp = function ($name) use ($adapter) {
+    return $adapter->driver->formatParameterName($name);
+};
+
+$sql = 'UPDATE ' . $qi('artist')
+    . ' SET ' . $qi('name') . ' = ' . $fp('name')
+    . ' WHERE ' . $qi('id') . ' = ' . $fp('id');
+
+$statement = $adapter->query($sql);
+
+$parameters = [
+    'name' => 'Updated Artist',
+    'id'   => 1,
+];
+
+$statement->execute($parameters);
+
+// DATA INSERTED, NOW CHECK
+
+$statement = $adapter->query(
+    'SELECT * FROM '
+    . $qi('artist')
+    . ' WHERE id = ' . $fp('id')
+);
+
+$results = $statement->execute(['id' => 1]);
+
+$row = $results->current();
+$name = $row['name'];
+```

+# RDBMS Metadata
+
+`Zend\Db\Metadata` is as sub-component of zend-db that makes it possible to get
+metadata information about tables, columns, constraints, triggers, and other
+information from a database in a standardized way. The primary interface for
+`Metadata` is:
+
+```php
+namespace Zend\Db\Metadata;
+
+interface MetadataInterface
+{
+    public function getSchemas();
+
+    public function getTableNames(string $schema = null, bool $includeViews = false) : string[];
+    public function getTables(string $schema = null, bool $includeViews = false) : Object\TableObject[];
+    public function getTable(string $tableName, string $schema = null) : Object\TableObject;
+
+    public function getViewNames(string $schema = null) : string[];
+    public function getViews(string $schema = null) : Object\ViewObject[];
+    public function getView(string $viewName, string $schema = null) : Object\ViewObject;
+
+    public function getColumnNames(string string $table, $schema = null) : string[];
+    public function getColumns(string $table, string $schema = null) : Object\ColumnObject[];
+    public function getColumn(string $columnName, string $table, string $schema = null) Object\ColumnObject;
+
+    public function getConstraints(string $table, $string schema = null) : Object\ConstraintObject[];
+    public function getConstraint(string $constraintName, string $table, string $schema = null) : Object\ConstraintObject;
+    public function getConstraintKeys(string $constraint, string $table, string $schema = null) : Object\ConstraintKeyObject[];
+
+    public function getTriggerNames(string $schema = null) : string[];
+    public function getTriggers(string $schema = null) : Object\TriggerObject[];
+    public function getTrigger(string $triggerName, string $schema = null) : Object\TriggerObject;
+}
+```
+
+## Basic Usage
+
+Usage of `Zend\Db\Metadata` involves:
+
+- Constructing a `Zend\Db\Metadata\Metadata` instance with an `Adapter`.
+- Choosing a strategy for retrieving metadata, based on the database platform
+  used. In most cases, information will come from querying the
+  `INFORMATION_SCHEMA` tables for the currently accessible schema.
+
+The `Metadata::get*Names()` methods will return arrays of strings, while the
+other methods will return value objects specific to the type queried.
+
+```php
+$metadata = new Zend\Db\Metadata\Metadata($adapter);
+
+// get the table names
+$tableNames = $metadata->getTableNames();
+
+foreach ($tableNames as $tableName) {
+    echo 'In Table ' . $tableName . PHP_EOL;
+
+    $table = $metadata->getTable($tableName);
+
+    echo '    With columns: ' . PHP_EOL;
+    foreach ($table->getColumns() as $column) {
+        echo '        ' . $column->getName()
+            . ' -> ' . $column->getDataType()
+            . PHP_EOL;
+    }
+
+    echo PHP_EOL;
+    echo '    With constraints: ' . PHP_EOL;
+
+    foreach ($metadata->getConstraints($tableName) as $constraint) {
+        echo '        ' . $constraint->getName()
+            . ' -> ' . $constraint->getType()
+            . PHP_EOL;
+
+        if (! $constraint->hasColumns()) {
+            continue;
+        }
+
+        echo '            column: ' . implode(', ', $constraint->getColumns());
+        if ($constraint->isForeignKey()) {
+            $fkCols = [];
+            foreach ($constraint->getReferencedColumns() as $refColumn) {
+                $fkCols[] = $constraint->getReferencedTableName() . '.' . $refColumn;
+            }
+            echo ' => ' . implode(', ', $fkCols);
+        }
+
+        echo PHP_EOL;
+    }
+
+    echo '----' . PHP_EOL;
+}
+```
+
+## Metadata value objects

+better explore the metadata. Below is the API for the various value objects:

+# Result Sets
+
+`Zend\Db\ResultSet` is a sub-component of zend-db for abstracting the iteration
+of results returned from queries producing rowsets. While data sources for this
+can be anything that is iterable, generally these will be populated from
+`Zend\Db\Adapter\Driver\ResultInterface` instances.
+
+Result sets must implement the `Zend\Db\ResultSet\ResultSetInterface`, and all
+sub-components of zend-db that return a result set as part of their API will
+assume an instance of a `ResultSetInterface` should be returned. In most cases,
+the prototype pattern will be used by consuming object to clone a prototype of
+a `ResultSet` and return a specialized `ResultSet` with a specific data source
+injected. `ResultSetInterface` is defined as follows:
+
+```php
+use Countable;
+use Traversable;
+
+interface ResultSetInterface extends Traversable, Countable
+{
+    public function initialize(mixed $dataSource) : void;
+    public function getFieldCount() : int;
+}
+```
+
+## Quick start
+
+`Zend\Db\ResultSet\ResultSet` is the most basic form of a `ResultSet` object
+that will expose each row as either an `ArrayObject`-like object or an array of
+row data. By default, `Zend\Db\Adapter\Adapter` will use a prototypical
+`Zend\Db\ResultSet\ResultSet` object for iterating when using the
+`Zend\Db\Adapter\Adapter::query()` method.
+
+The following is an example workflow similar to what one might find inside
+`Zend\Db\Adapter\Adapter::query()`:
+
+```php
+use Zend\Db\Adapter\Driver\ResultInterface;
+use Zend\Db\ResultSet\ResultSet;
+
+$statement = $driver->createStatement('SELECT * FROM users');
+$statement->prepare();
+$result = $statement->execute($parameters);
+
+if ($result instanceof ResultInterface && $result->isQueryResult()) {
+    $resultSet = new ResultSet;
+    $resultSet->initialize($result);
+
+    foreach ($resultSet as $row) {
+        echo $row->my_column . PHP_EOL;
+    }
+}
+```
+
+## Zend\\Db\\ResultSet\\ResultSet and Zend\\Db\\ResultSet\\AbstractResultSet
+
+For most purposes, either an instance of `Zend\Db\ResultSet\ResultSet` or a
+derivative of `Zend\Db\ResultSet\AbstractResultSet` will be used. The
+implementation of the `AbstractResultSet` offers the following core
+functionality:
+
+```php
+namespace Zend\Db\ResultSet;
+
+use Iterator;
+
+abstract class AbstractResultSet implements Iterator, ResultSetInterface
+{
+    public function initialize(array|Iterator|IteratorAggregate|ResultInterface $dataSource) : self;
+    public function getDataSource() : Iterator|IteratorAggregate|ResultInterface;
+    public function getFieldCount() : int;
+
+    /** Iterator */
+    public function next() : mixed;
+    public function key() : string|int;
+    public function current() : mixed;
+    public function valid() : bool;
+    public function rewind() : void;
+
+    /** countable */
+    public function count() : int;
+
+    /** get rows as array */
+    public function toArray() : array;
+}
+```
+
+## Zend\\Db\\ResultSet\\HydratingResultSet
+
+`Zend\Db\ResultSet\HydratingResultSet` is a more flexible `ResultSet` object
+that allows the developer to choose an appropriate "hydration strategy" for
+getting row data into a target object.  While iterating over results,
+`HydratingResultSet` will take a prototype of a target object and clone it once
+for each row. The `HydratingResultSet` will then hydrate that clone with the
+row data.
+
+The `HydratingResultSet` depends on
+[zend-hydrator](https://docs.zendframework.com/zend-hydrator), which you will
+need to install:
+
+```bash
+$ composer require zendframework/zend-hydrator
+```
+
+In the example below, rows from the database will be iterated, and during
+iteration, `HydratingResultSet` will use the `Reflection` based hydrator to
+inject the row data directly into the protected members of the cloned
+`UserEntity` object:
+
+```php
+use Zend\Db\Adapter\Driver\ResultInterface;
+use Zend\Db\ResultSet\HydratingResultSet;
+use Zend\Hydrator\Reflection as ReflectionHydrator;
+
+class UserEntity
+{
+    protected $first_name;
+    protected $last_name;
+
+    public function getFirstName()
+    {
+        return $this->first_name;
+    }
+
+    public function getLastName()
+    {
+        return $this->last_name;
+    }
+
+    public function setFirstName($firstName)
+    {
+        $this->first_name = $firstName;
+    }
+
+    public function setLastName($lastName)
+    {
+        $this->last_name = $lastName;
+    }
+}
+
+$statement = $driver->createStatement($sql);
+$statement->prepare($parameters);
+$result = $statement->execute();
+
+if ($result instanceof ResultInterface && $result->isQueryResult()) {
+    $resultSet = new HydratingResultSet(new ReflectionHydrator, new UserEntity);
+    $resultSet->initialize($result);
+
+    foreach ($resultSet as $user) {
+        echo $user->getFirstName() . ' ' . $user->getLastName() . PHP_EOL;
+    }
+}
+```
+
+For more information, see the [zend-hydrator](https://docs.zendframework.com/zend-hydrator/)
+documentation to get a better sense of the different strategies that can be
+employed in order to populate a target object.

+# Row Gateways
+
+`Zend\Db\RowGateway` is a sub-component of zend-db that implements the Row Data
+Gateway pattern described in the book [Patterns of Enterprise Application
+Architecture](http://www.martinfowler.com/books/eaa.html). Row Data Gateways
+model individual rows of a database table, and provide methods such as `save()`
+and `delete()` that persist the row to the database. Likewise, after a row from
+the database is retrieved, it can then be manipulated and `save()`'d back to
+the database in the same position (row), or it can be `delete()`'d from the
+table.
+
+`RowGatewayInterface` defines the methods `save()` and `delete()`:
+
+```php
+namespace Zend\Db\RowGateway;
+
+interface RowGatewayInterface
+{
+    public function save();
+    public function delete();
+}
+```
+
+## Quick start
+
+`RowGateway` is generally used in conjunction with objects that produce
+`Zend\Db\ResultSet`s, though it may also be used standalone.  To use it
+standalone, you need an `Adapter` instance and a set of data to work with.
+
+The following demonstrates a basic use case.
+
+```php
+use Zend\Db\RowGateway\RowGateway;
+
+// Query the database:
+$resultSet = $adapter->query('SELECT * FROM `user` WHERE `id` = ?', [2]);
+
+// Get array of data:
+$rowData = $resultSet->current()->getArrayCopy();
+
+// Create a row gateway:
+$rowGateway = new RowGateway('id', 'my_table', $adapter);
+$rowGateway->populate($rowData, true);
+
+// Manipulate the row and persist it:
+$rowGateway->first_name = 'New Name';
+$rowGateway->save();
+
+// Or delete this row:
+$rowGateway->delete();
+```
+
+The workflow described above is greatly simplified when `RowGateway` is used in
+conjunction with the [TableGateway RowGatewayFeature](table-gateway.md#tablegateway-features).
+In that paradigm, `select()` operations will produce a `ResultSet` that iterates
+`RowGateway` instances.
+
+As an example:
+
+```php
+use Zend\Db\TableGateway\Feature\RowGatewayFeature;
+use Zend\Db\TableGateway\TableGateway;
+
+$table = new TableGateway('artist', $adapter, new RowGatewayFeature('id'));
+$results = $table->select(['id' => 2]);
+
+$artistRow = $results->current();
+$artistRow->name = 'New Name';
+$artistRow->save();
+```
+
+## ActiveRecord Style Objects
+
+If you wish to have custom behaviour in your `RowGateway` objects &mdash;
+essentially making them behave similarly to the
+[ActiveRecord](http://www.martinfowler.com/eaaCatalog/activeRecord.html)
+pattern), pass a prototype object implementing the `RowGatewayInterface` to the
+`RowGatewayFeature` constructor instead of a primary key:
+
+```php
+use Zend\Db\TableGateway\Feature\RowGatewayFeature;
+use Zend\Db\TableGateway\TableGateway;
+use Zend\Db\RowGateway\RowGatewayInterface;
+
+class Artist implements RowGatewayInterface
+{
+    protected $adapter;
+
+    public function __construct($adapter)
+    {
+       $this->adapter = $adapter;
+    }
+
+    // ... save() and delete() implementations
+}
+
+$table = new TableGateway('artist', $adapter, new RowGatewayFeature(new Artist($adapter)));
+```

+# DDL Abstraction
+
+`Zend\Db\Sql\Ddl` is a sub-component of `Zend\Db\Sql` allowing creation of DDL
+(Data Definition Language) SQL statements. When combined with a platform
+specific `Zend\Db\Sql\Sql` object, DDL objects are capable of producing
+platform-specific `CREATE TABLE` statements, with specialized data types,
+constraints, and indexes for a database/schema.
+
+The following platforms have platform specializations for DDL:
+
+- MySQL
+- All databases compatible with ANSI SQL92
+
+## Creating Tables
+
+Like `Zend\Db\Sql` objects, each statement type is represented by a class. For
+example, `CREATE TABLE` is modeled by the `CreateTable` class; this is likewise
+the same for `ALTER TABLE` (as `AlterTable`), and `DROP TABLE` (as
+`DropTable`). You can create instances using a number of approaches:
+
+```php
+use Zend\Db\Sql\Ddl;
+
+$table = new Ddl\CreateTable();
+
+// With a table name:
+$table = new Ddl\CreateTable('bar');
+
+// Optionally, as a temporary table:
+$table = new Ddl\CreateTable('bar', true);
+```
+
+You can also set the table after instantiation:
+
+```php
+$table->setTable('bar');
+```
+
+Currently, columns are added by creating a column object (described in the
+[data type table below](#currently-supported-data-types)):
+
+```php
+use Zend\Db\Sql\Ddl\Column;
+
+$table->addColumn(new Column\Integer('id'));
+$table->addColumn(new Column\Varchar('name', 255));
+```
+
+Beyond adding columns to a table, you may also add constraints:
+
+```php
+use Zend\Db\Sql\Ddl\Constraint;
+
+$table->addConstraint(new Constraint\PrimaryKey('id'));
+$table->addConstraint(
+    new Constraint\UniqueKey(['name', 'foo'], 'my_unique_key')
+);
+```
+You can also use the `AUTO_INCREMENT` attribute for MySQL:
+```php
+use Zend\Db\Sql\Ddl\Column;
+
+$column = new Column\Integer('id');
+$column->setOption('AUTO_INCREMENT', true);
+```
+
+## Altering Tables
+
+Similar to `CreateTable`, you may also use `AlterTable` instances:
+
+```php
+use Zend\Db\Sql\Ddl;
+
+$table = new Ddl\AlterTable();
+
+// With a table name:
+$table = new Ddl\AlterTable('bar');
+
+// Optionally, as a temporary table:
+$table = new Ddl\AlterTable('bar', true);
+```
+
+The primary difference between a `CreateTable` and `AlterTable` is that the
+`AlterTable` takes into account that the table and its assets already exist.
+Therefore, while you still have `addColumn()` and `addConstraint()`, you will
+also have the ability to *alter* existing columns:
+
+```php
+use Zend\Db\Sql\Ddl\Column;
+
+$table->changeColumn('name', Column\Varchar('new_name', 50));
+```
+
+You may also *drop* existing columns or constraints:
+
+```php
+$table->dropColumn('foo');
+$table->dropConstraint('my_index');
+```
+
+## Dropping Tables
+
+To drop a table, create a `DropTable` instance:
+
+```php
+$drop = new Ddl\DropTable('bar');
+```
+
+## Executing DDL Statements
+
+After a DDL statement object has been created and configured, at some point you
+will need to execute the statement. This requires an `Adapter` instance and a
+properly seeded `Sql` instance.
+
+The workflow looks something like this, with `$ddl` being a `CreateTable`,
+`AlterTable`, or `DropTable` instance:
+
+```php
+use Zend\Db\Sql\Sql;
+
+// Existence of $adapter is assumed.
+$sql = new Sql($adapter);
+
+$adapter->query(
+    $sql->getSqlStringForSqlObject($ddl),
+    $adapter::QUERY_MODE_EXECUTE
+);
+```
+
+By passing the `$ddl` object through the `$sql` instance's
+`getSqlStringForSqlObject()` method, we ensure that any platform specific
+specializations/modifications are utilized to create a platform specific SQL
+statement.
+
+Next, using the constant `Zend\Db\Adapter\Adapter::QUERY_MODE_EXECUTE` ensures
+that the SQL statement is not prepared, as most DDL statements on most
+platforms cannot be prepared, only executed.
+
+## Currently Supported Data Types
+
+These types exist in the `Zend\Db\Sql\Ddl\Column` namespace. Data types must
+implement `Zend\Db\Sql\Ddl\Column\ColumnInterface`.
+
+In alphabetical order:
+
+Type             | Arguments For Construction
+-----------------|---------------------------
+BigInteger       | `$name`, `$nullable = false`, `$default = null`, `array $options = array()`
+Binary           | `$name`, `$length`, `nullable = false`, `$default = null`, `array $options = array()`
+Blob             | `$name`, `$length`, `nullable = false`, `$default = null`, `array $options = array()`
+Boolean          | `$name`
+Char             | `$name`, `length`
+Column (generic) | `$name = null`
+Date             | `$name`
+DateTime         | `$name`
+Decimal          | `$name`, `$precision`, `$scale = null`
+Float            | `$name`, `$digits`, `$decimal` (Note: this class is deprecated as of 2.4.0; use Floating instead)
+Floating         | `$name`, `$digits`, `$decimal`
+Integer          | `$name`, `$nullable = false`, `default = null`, `array $options = array()`
+Text             | `$name`, `$length`, `nullable = false`, `$default = null`, `array $options = array()`
+Time             | `$name`
+Timestamp        | `$name`
+Varbinary        | `$name`, `$length`
+Varchar          | `$name`, `$length`
+
+Each of the above types can be utilized in any place that accepts a `Column\ColumnInterface`
+instance. Currently, this is primarily in `CreateTable::addColumn()` and `AlterTable`'s
+`addColumn()` and `changeColumn()` methods.
+
+## Currently Supported Constraint Types
+
+These types exist in the `Zend\Db\Sql\Ddl\Constraint` namespace. Data types
+must implement `Zend\Db\Sql\Ddl\Constraint\ConstraintInterface`.
+
+In alphabetical order:
+
+Type       | Arguments For Construction
+-----------|---------------------------
+Check      | `$expression`, `$name`
+ForeignKey | `$name`, `$column`, `$referenceTable`, `$referenceColumn`, `$onDeleteRule = null`, `$onUpdateRule = null`
+PrimaryKey | `$columns`
+UniqueKey  | `$column`, `$name = null`
+
+Each of the above types can be utilized in any place that accepts a
+`Column\ConstraintInterface` instance. Currently, this is primarily in
+`CreateTable::addConstraint()` and `AlterTable::addConstraint()`.

+# SQL Abstraction
+
+`Zend\Db\Sql` is a SQL abstraction layer for building platform-specific SQL
+queries via an object-oriented API. The end result of a `Zend\Db\Sql` object
+will be to either produce a `Statement` and `ParameterContainer` that
+represents the target query, or a full string that can be directly executed
+against the database platform. To achieve this, `Zend\Db\Sql` objects require a
+`Zend\Db\Adapter\Adapter` object in order to produce the desired results.
+
+## Quick start
+
+There are four primary tasks associated with interacting with a database
+defined by Data Manipulation Language (DML): selecting, inserting, updating,
+and deleting. As such, there are four primary classes that developers can
+interact with in order to build queries in the `Zend\Db\Sql` namespace:
+`Select`, `Insert`, `Update`, and `Delete`.
+
+Since these four tasks are so closely related and generally used together
+within the same application, the `Zend\Db\Sql\Sql` class helps you create them
+and produce the result you are attempting to achieve.
+
+```php
+use Zend\Db\Sql\Sql;
+
+$sql    = new Sql($adapter);
+$select = $sql->select(); // returns a Zend\Db\Sql\Select instance
+$insert = $sql->insert(); // returns a Zend\Db\Sql\Insert instance
+$update = $sql->update(); // returns a Zend\Db\Sql\Update instance
+$delete = $sql->delete(); // returns a Zend\Db\Sql\Delete instance
+```
+
+As a developer, you can now interact with these objects, as described in the
+sections below, to customize each query. Once they have been populated with
+values, they are ready to either be prepared or executed.
+
+To prepare (using a Select object):
+
+```php
+use Zend\Db\Sql\Sql;
+
+$sql    = new Sql($adapter);
+$select = $sql->select();
+$select->from('foo');
+$select->where(['id' => 2]);
+
+$statement = $sql->prepareStatementForSqlObject($select);
+$results = $statement->execute();
+```
+
+To execute (using a Select object)
+
+```php
+use Zend\Db\Sql\Sql;
+
+$sql    = new Sql($adapter);
+$select = $sql->select();
+$select->from('foo');
+$select->where(['id' => 2]);
+
+$selectString = $sql->buildSqlString($select);
+$results = $adapter->query($selectString, $adapter::QUERY_MODE_EXECUTE);
+```
+
+`Zend\\Db\\Sql\\Sql` objects can also be bound to a particular table so that in
+obtaining a `Select`, `Insert`, `Update`, or `Delete` instance, the object will be
+seeded with the table:
+
+```php
+use Zend\Db\Sql\Sql;
+
+$sql    = new Sql($adapter, 'foo');
+$select = $sql->select();
+$select->where(['id' => 2]); // $select already has from('foo') applied
+```
+
+## Common interfaces for SQL implementations
+
+Each of these objects implements the following two interfaces:
+
+```php
+interface PreparableSqlInterface
+{
+     public function prepareStatement(Adapter $adapter, StatementInterface $statement) : void;
+}
+
+interface SqlInterface
+{
+     public function getSqlString(PlatformInterface $adapterPlatform = null) : string;
+}
+```
+
+Use these functions to produce either (a) a prepared statement, or (b) a string
+to execute.
+
+## Select
+
+`Zend\Db\Sql\Select` presents a unified API for building platform-specific SQL
+SELECT queries. Instances may be created and consumed without
+`Zend\Db\Sql\Sql`:
+
+```php
+use Zend\Db\Sql\Select;
+
+$select = new Select();
+// or, to produce a $select bound to a specific table
+$select = new Select('foo');
+```
+
+If a table is provided to the `Select` object, then `from()` cannot be called
+later to change the name of the table.
+
+Once you have a valid `Select` object, the following API can be used to further
+specify various select statement parts:
+
+```php
+class Select extends AbstractSql implements SqlInterface, PreparableSqlInterface
+{
+    const JOIN_INNER = 'inner';
+    const JOIN_OUTER = 'outer';
+    const JOIN_LEFT = 'left';
+    const JOIN_RIGHT = 'right';
+    const SQL_STAR = '*';
+    const ORDER_ASCENDING = 'ASC';
+    const ORDER_DESCENDING = 'DESC';
+
+    public $where; // @param Where $where
+
+    public function __construct(string|array|TableIdentifier $table = null);
+    public function from(string|array|TableIdentifier $table) : self;
+    public function columns(array $columns, bool $prefixColumnsWithTable = true) : self;
+    public function join(string|array $name, string $on, string|array $columns = self::SQL_STAR, string $type = self::JOIN_INNER) : self;
+    public function where(Where|callable|string|array|PredicateInterface $predicate, string $combination = Predicate\PredicateSet::OP_AND) : self;
+    public function group(string|array $group);
+    public function having(Having|callable|string|array $predicate, string $combination = Predicate\PredicateSet::OP_AND) : self;
+    public function order(string|array $order) : self;
+    public function limit(int $limit) : self;
+    public function offset(int $offset) : self;
+}
+```
+
+### from()
+
+```php
+// As a string:
+$select->from('foo');
+
+// As an array to specify an alias
+// (produces SELECT "t".* FROM "table" AS "t")
+$select->from(['t' => 'table']);
+
+// Using a Sql\TableIdentifier:
+// (same output as above)
+$select->from(['t' => new TableIdentifier('table')]);
+```
+
+### columns()
+
+```php
+// As an array of names
+$select->columns(['foo', 'bar']);
+
+// As an associative array with aliases as the keys
+// (produces 'bar' AS 'foo', 'bax' AS 'baz')
+$select->columns([
+    'foo' => 'bar', 
+    'baz' => 'bax'
+]);
+
+// Sql function call on the column
+// (produces CONCAT_WS('/', 'bar', 'bax') AS 'foo')
+$select->columns([
+    'foo' => new \Zend\Db\Sql\Expression("CONCAT_WS('/', 'bar', 'bax')")
+]);
+```
+
+### join()
+
+```php
+$select->join(
+    'foo',              // table name
+    'id = bar.id',      // expression to join on (will be quoted by platform object before insertion),
+    ['bar', 'baz'],     // (optional) list of columns, same requirements as columns() above
+    $select::JOIN_OUTER // (optional), one of inner, outer, left, right also represented by constants in the API
+);
+
+$select
+    ->from(['f' => 'foo'])     // base table
+    ->join(
+        ['b' => 'bar'],        // join table with alias
+        'f.foo_id = b.foo_id'  // join expression
+    );
+```
+
+### where(), having()
+
+`Zend\Db\Sql\Select` provides bit of flexibility as it regards to what kind of
+parameters are acceptable when calling `where()` or `having()`. The method
+signature is listed as:
+
+```php
+/**
+ * Create where clause
+ *
+ * @param  Where|callable|string|array $predicate
+ * @param  string $combination One of the OP_* constants from Predicate\PredicateSet
+ * @return Select
+ */
+public function where($predicate, $combination = Predicate\PredicateSet::OP_AND);
+```
+
+If you provide a `Zend\Db\Sql\Where` instance to `where()` or a
+`Zend\Db\Sql\Having` instance to `having()`, any previous internal instances
+will be replaced completely. When either instance is processed, this object will
+be iterated to produce the WHERE or HAVING section of the SELECT statement.
+
+If you provide a PHP callable to `where()` or `having()`, this function will be
+called with the `Select`'s `Where`/`Having` instance as the only parameter.
+This enables code like the following:
+
+```php
+$select->where(function (Where $where) {
+    $where->like('username', 'ralph%');
+});
+```
+
+If you provide a *string*, this string will be used to create a
+`Zend\Db\Sql\Predicate\Expression` instance, and its contents will be applied
+as-is, with no quoting:
+
+```php
+// SELECT "foo".* FROM "foo" WHERE x = 5
+$select->from('foo')->where('x = 5');
+```
+
+If you provide an array with integer indices, the value can be one of:
+
+- a string; this will be used to build a `Predicate\Expression`.
+- any object implementing `Predicate\PredicateInterface`.
+
+In either case, the instances are pushed onto the `Where` stack with the
+`$combination` provided (defaulting to `AND`).
+
+As an example:
+
+```php
+// SELECT "foo".* FROM "foo" WHERE x = 5 AND y = z
+$select->from('foo')->where(['x = 5', 'y = z']);
+```
+
+If you provide an associative array with string keys, any value with a string
+key will be cast as follows:
+
+PHP value | Predicate type
+--------- | --------------
+`null`    | `Predicate\IsNull`
+`array`   | `Predicate\In`
+`string`  | `Predicate\Operator`, where the key is the identifier.
+
+As an example:
+
+```php
+// SELECT "foo".* FROM "foo" WHERE "c1" IS NULL AND "c2" IN (?, ?, ?) AND "c3" IS NOT NULL
+$select->from('foo')->where([
+    'c1' => null,
+    'c2' => [1, 2, 3],
+    new \Zend\Db\Sql\Predicate\IsNotNull('c3'),
+]);
+```
+
+As another example of complex queries with nested conditions e.g.
+
+```sql
+SELECT * WHERE (column1 is null or column1 = 2) AND (column2 = 3)
+```
+
+you need to use the `nest()` and `unnest()` methods, as follows:
+
+```php
+$select->where->nest() // bracket opened
+    ->isNull('column1')
+    ->or
+    ->equalTo('column1', '2')
+    ->unnest();  // bracket closed
+    ->equalTo('column2', '3');
+```
+
+### order()
+
+```php
+$select = new Select;
+$select->order('id DESC'); // produces 'id' DESC
+
+$select = new Select;
+$select
+    ->order('id DESC')
+    ->order('name ASC, age DESC'); // produces 'id' DESC, 'name' ASC, 'age' DESC
+
+$select = new Select;
+$select->order(['name ASC', 'age DESC']); // produces 'name' ASC, 'age' DESC
+```
+
+### limit() and offset()
+
+```php
+$select = new Select;
+$select->limit(5);   // always takes an integer/numeric
+$select->offset(10); // similarly takes an integer/numeric
+```
+
+## Insert
+
+The Insert API:
+
+```php
+class Insert implements SqlInterface, PreparableSqlInterface
+{
+    const VALUES_MERGE = 'merge';
+    const VALUES_SET   = 'set';
+
+    public function __construct(string|TableIdentifier $table = null);
+    public function into(string|TableIdentifier $table) : self;
+    public function columns(array $columns) : self;
+    public function values(array $values, string $flag = self::VALUES_SET) : self;
+}
+```
+
+As with `Select`, the table may be provided during instantiation or via the
+`into()` method.
+
+### columns()
+
+```php
+$insert->columns(['foo', 'bar']); // set the valid columns
+```
+
+### values()
+
+```php
+// The default behavior of values is to set the values;
+// successive calls will not preserve values from previous calls.
+$insert->values([
+    'col_1' => 'value1',
+    'col_2' => 'value2',
+]);
+```
+
+```php
+// To merge values with previous calls, provide the appropriate flag:
+$insert->values(['col_2' => 'value2'], $insert::VALUES_MERGE);
+```
+
+## Update
+
+```php
+class Update
+{
+    const VALUES_MERGE = 'merge';
+    const VALUES_SET   = 'set';
+
+    public $where; // @param Where $where
+    public function __construct(string|TableIdentifier $table = null);
+    public function table(string|TableIdentifier $table) : self;
+    public function set(array $values, string $flag = self::VALUES_SET) : self;
+    public function where(Where|callable|string|array|PredicateInterface $predicate, string $combination = Predicate\PredicateSet::OP_AND) : self;
+}
+```
+
+### set()
+
+```php
+$update->set(['foo' => 'bar', 'baz' => 'bax']);
+```
+
+### where()
+
+See the [section on Where and Having](#where-and-having).
+
+## Delete
+
+```php
+class Delete
+{
+    public $where; // @param Where $where
+
+    public function __construct(string|TableIdentifier $table = null);
+    public function from(string|TableIdentifier $table);
+    public function where(Where|callable|string|array|PredicateInterface $predicate, string $combination = Predicate\PredicateSet::OP_AND) : self;
+}
+```
+
+### where()
+
+See the [section on Where and Having](#where-and-having).
+
+## Where and Having
+
+In the following, we will talk about `Where`; note, however, that `Having`
+utilizes the same API.
+
+Effectively, `Where` and `Having` extend from the same base object, a
+`Predicate` (and `PredicateSet`). All of the parts that make up a WHERE or
+HAVING clause that are AND'ed or OR'd together are called *predicates*.  The
+full set of predicates is called a `PredicateSet`. A `Predicate` generally
+contains the values (and identifiers) separate from the fragment they belong to
+until the last possible moment when the statement is either prepared
+(parameteritized) or executed. In parameterization, the parameters will be
+replaced with their proper placeholder (a named or positional parameter), and
+the values stored inside an `Adapter\ParameterContainer`. When executed, the
+values will be interpolated into the fragments they belong to and properly
+quoted.
+
+In the `Where`/`Having` API, a distinction is made between what elements are
+considered identifiers (`TYPE_IDENTIFIER`) and which are values (`TYPE_VALUE`).
+There is also a special use case type for literal values (`TYPE_LITERAL`). All
+element types are expressed via the `Zend\Db\Sql\ExpressionInterface`
+interface.
+
+> ### Literals
+>
+> In ZF 2.1, an actual `Literal` type was added. `Zend\Db\Sql` now makes the
+> distinction that literals will not have any parameters that need
+> interpolating, while `Expression` objects *might* have parameters that need
+> interpolating. In cases where there are parameters in an `Expression`,
+> `Zend\Db\Sql\AbstractSql` will do its best to identify placeholders when the
+> `Expression` is processed during statement creation. In short, if you don't
+> have parameters, use `Literal` objects.
+
+The `Where` and `Having` API is that of `Predicate` and `PredicateSet`:
+
+```php
+// Where & Having extend Predicate:
+class Predicate extends PredicateSet
+{
+    public $and;
+    public $or;
+    public $AND;
+    public $OR;
+    public $NEST;
+    public $UNNEST;
+
+    public function nest() : Predicate;
+    public function setUnnest(Predicate $predicate) : void;
+    public function unnest() : Predicate;
+    public function equalTo(
+        int|float|bool|string $left,
+        int|float|bool|string $right,
+        string $leftType = self::TYPE_IDENTIFIER,
+        string $rightType = self::TYPE_VALUE
+    ) : self;
+    public function notEqualTo(
+        int|float|bool|string $left,
+        int|float|bool|string $right,
+        string $leftType = self::TYPE_IDENTIFIER,
+        string $rightType = self::TYPE_VALUE
+    ) : self;
+    public function lessThan(
+        int|float|bool|string $left,
+        int|float|bool|string $right,
+        string $leftType = self::TYPE_IDENTIFIER,
+        string $rightType = self::TYPE_VALUE
+    ) : self;
+    public function greaterThan(
+        int|float|bool|string $left,
+        int|float|bool|string $right,
+        string $leftType = self::TYPE_IDENTIFIER,
+        string $rightType = self::TYPE_VALUE
+    ) : self;
+    public function lessThanOrEqualTo(
+        int|float|bool|string $left,
+        int|float|bool|string $right,
+        string $leftType = self::TYPE_IDENTIFIER,
+        string $rightType = self::TYPE_VALUE
+    ) : self;
+    public function greaterThanOrEqualTo(
+        int|float|bool|string $left,
+        int|float|bool|string $right,
+        string $leftType = self::TYPE_IDENTIFIER,
+        string $rightType = self::TYPE_VALUE
+    ) : self;
+    public function like(string $identifier, string $like) : self;
+    public function notLike(string $identifier, string $notLike) : self;
+    public function literal(string $literal) : self;
+    public function expression(string $expression, array $parameters = null) : self;
+    public function isNull(string $identifier) : self;
+    public function isNotNull(string $identifier) : self;
+    public function in(string $identifier, array $valueSet = []) : self;
+    public function notIn(string $identifier, array $valueSet = []) : self;
+    public function between(
+        string $identifier,
+        int|float|string $minValue,
+        int|float|string $maxValue
+    ) : self;
+    public function notBetween(
+        string $identifier,
+        int|float|string $minValue,
+        int|float|string $maxValue
+    ) : self;
+    public function predicate(PredicateInterface $predicate) : self;
+
+    // Inherited From PredicateSet
+
+    public function addPredicate(PredicateInterface $predicate, $combination = null) : self;
+    public function getPredicates() PredicateInterface[];
+    public function orPredicate(PredicateInterface $predicate) : self;
+    public function andPredicate(PredicateInterface $predicate) : self;
+    public function getExpressionData() : array;
+    public function count() : int;
+}
+```
+
+Each method in the API will produce a corresponding `Predicate` object of a similarly named
+type, as described below.
+
+### equalTo(), lessThan(), greaterThan(), lessThanOrEqualTo(), greaterThanOrEqualTo()
+
+```php
+$where->equalTo('id', 5);
+
+// The above is equivalent to:
+$where->addPredicate(
+    new Predicate\Operator($left, Operator::OPERATOR_EQUAL_TO, $right, $leftType, $rightType)
+);
+```
+
+Operators use the following API:
+
+```php
+class Operator implements PredicateInterface
+{
+    const OPERATOR_EQUAL_TO                  = '=';
+    const OP_EQ                              = '=';
+    const OPERATOR_NOT_EQUAL_TO              = '!=';
+    const OP_NE                              = '!=';
+    const OPERATOR_LESS_THAN                 = '<';
+    const OP_LT                              = '<';
+    const OPERATOR_LESS_THAN_OR_EQUAL_TO     = '<=';
+    const OP_LTE                             = '<=';
+    const OPERATOR_GREATER_THAN              = '>';

+# Table Gateways
+
+The Table Gateway subcomponent provides an object-oriented representation of a
+database table; its methods mirror the most common table operations. In code,
+the interface resembles:
+
+```php
+namespace Zend\Db\TableGateway;
+
+use Zend\Db\ResultSet\ResultSetInterface;
+use Zend\Db\Sql\Where;
+
+interface TableGatewayInterface
+{
+    public function getTable() : string;
+    public function select(Where|callable|string|array $where = null) : ResultSetInterface;
+    public function insert(array $set) : int;
+    public function update(
+        array $set,
+        Where|callable|string|array $where = null,
+        array $joins = null
+    ) : int;
+    public function delete(Where|callable|string|array $where) : int;
+}
+```
+
+There are two primary implementations of the `TableGatewayInterface`,
+`AbstractTableGateway` and `TableGateway`. The `AbstractTableGateway` is an
+abstract basic implementation that provides functionality for `select()`,
+`insert()`, `update()`, `delete()`, as well as an additional API for doing
+these same kinds of tasks with explicit `Zend\Db\Sql` objects: `selectWith()`,
+`insertWith()`, `updateWith()`, and `deleteWith()`. In addition,
+AbstractTableGateway also implements a "Feature" API, that allows for expanding
+the behaviors of the base `TableGateway` implementation without having to
+extend the class with this new functionality.  The `TableGateway` concrete
+implementation simply adds a sensible constructor to the `AbstractTableGateway`
+class so that out-of-the-box, `TableGateway` does not need to be extended in
+order to be consumed and utilized to its fullest.
+
+## Quick start
+
+The following example uses `Zend\Db\TableGateway\TableGateway`, which defines
+the following API:
+
+```php
+namespace Zend\Db\TableGateway;
+
+use Zend\Db\Adapter\AdapterInterface;
+use Zend\Db\ResultSet\ResultSet;
+use Zend\Db\ResultSet\ResultSetInterface;
+use Zend\Db\Sql;
+use Zend\Db\Sql\TableIdentifier;
+
+class TableGateway extends AbstractTableGateway
+{
+    public $lastInsertValue;
+    public $table;
+    public $adapter;
+
+    public function __construct(
+        string|TableIdentifier $table,
+        AdapterInterface $adapter,
+        Feature\AbstractFeature|Feature\FeatureSet|Feature\AbstractFeature[] $features = null,
+        ResultSetInterface $resultSetPrototype = null,
+        Sql\Sql $sql = null
+    );
+
+    /** Inherited from AbstractTableGateway */
+
+    public function isInitialized() : bool;
+    public function initialize() : void;
+    public function getTable() : string;
+    public function getAdapter() : AdapterInterface;
+    public function getColumns() : array;
+    public function getFeatureSet() Feature\FeatureSet;
+    public function getResultSetPrototype() : ResultSetInterface;
+    public function getSql() | Sql\Sql;
+    public function select(Sql\Where|callable|string|array $where = null) : ResultSetInterface;
+    public function selectWith(Sql\Select $select) : ResultSetInterface;
+    public function insert(array $set) : int;
+    public function insertWith(Sql\Insert $insert) | int;
+    public function update(
+        array $set,
+        Sql\Where|callable|string|array $where = null,
+        array $joins = null
+    ) : int;
+    public function updateWith(Sql\Update $update) : int;
+    public function delete(Sql\Where|callable|string|array $where) : int;
+    public function deleteWith(Sql\Delete $delete) : int;
+    public function getLastInsertValue() : int;
+}
+```
+
+The concrete `TableGateway` object uses constructor injection for getting
+dependencies and options into the instance. The table name and an instance of
+an `Adapter` are all that is required to create an instance.
+
+Out of the box, this implementation makes no assumptions about table structure
+or metadata, and when `select()` is executed, a simple `ResultSet` object with
+the populated `Adapter`'s `Result` (the datasource) will be returned and ready
+for iteration.
+
+```php
+use Zend\Db\TableGateway\TableGateway;
+
+$projectTable = new TableGateway('project', $adapter);
+$rowset = $projectTable->select(['type' => 'PHP']);
+
+echo 'Projects of type PHP: ' . PHP_EOL;
+foreach ($rowset as $projectRow) {
+    echo $projectRow['name'] . PHP_EOL;
+}
+
+// Or, when expecting a single row:
+$artistTable = new TableGateway('artist', $adapter);
+$rowset      = $artistTable->select(['id' => 2]);
+$artistRow   = $rowset->current();
+
+var_dump($artistRow);
+```
+
+The `select()` method takes the same arguments as
+`Zend\Db\Sql\Select::where()`; arguments will be passed to the `Select`
+instance used to build the SELECT query. This means the following is possible:
+
+```php
+use Zend\Db\TableGateway\TableGateway;
+use Zend\Db\Sql\Select;
+
+$artistTable = new TableGateway('artist', $adapter);
+
+// Search for at most 2 artists who's name starts with Brit, ascending:
+$rowset = $artistTable->select(function (Select $select) {
+    $select->where->like('name', 'Brit%');
+    $select->order('name ASC')->limit(2);
+});
+```
+
+## TableGateway Features
+
+The Features API allows for extending the functionality of the base
+`TableGateway` object without having to polymorphically extend the base class.
+This allows for a wider array of possible mixing and matching of features to
+achieve a particular behavior that needs to be attained to make the base
+implementation of `TableGateway` useful for a particular problem.
+
+With the `TableGateway` object, features should be injected though the
+constructor. The constructor can take features in 3 different forms:
+
+- as a single `Feature` instance
+- as a `FeatureSet` instance
+- as an array of `Feature` instances
+
+There are a number of features built-in and shipped with zend-db:
+
+- `GlobalAdapterFeature`: the ability to use a global/static adapter without
+  needing to inject it into a `TableGateway` instance. This is only useful when
+  you are extending the `AbstractTableGateway` implementation:
+
+    ```php
+    use Zend\Db\TableGateway\AbstractTableGateway;
+    use Zend\Db\TableGateway\Feature;
+
+    class MyTableGateway extends AbstractTableGateway
+    {
+        public function __construct()
+        {
+            $this->table      = 'my_table';
+            $this->featureSet = new Feature\FeatureSet();
+            $this->featureSet->addFeature(new Feature\GlobalAdapterFeature());
+            $this->initialize();
+        }
+    }
+
+    // elsewhere in code, in a bootstrap
+    Zend\Db\TableGateway\Feature\GlobalAdapterFeature::setStaticAdapter($adapter);
+
+    // in a controller, or model somewhere
+    $table = new MyTableGateway(); // adapter is statically loaded
+    ```
+
+- `MasterSlaveFeature`: the ability to use a master adapter for `insert()`,
+  `update()`, and `delete()`, but switch to a slave adapter for all `select()`
+  operations.
+
+    ```php
+    $table = new TableGateway('artist', $adapter, new Feature\MasterSlaveFeature($slaveAdapter));
+    ```
+
+- `MetadataFeature`: the ability populate `TableGateway` with column
+  information from a `Metadata` object. It will also store the primary key
+  information in case the `RowGatewayFeature` needs to consume this information.
+
+    ```php
+    $table = new TableGateway('artist', $adapter, new Feature\MetadataFeature());
+    ```
+
+- `EventFeature`: the ability to compose a
+  [zend-eventmanager](https://github.com/zendframework/zend-eventmanager)
+  `EventManager` instance within your `TableGateway` instance, and attach
+  listeners to the various events of its lifecycle.
+
+    ```php
+    $table = new TableGateway('artist', $adapter, new Feature\EventFeature($eventManagerInstance));
+    ```
+
+- `RowGatewayFeature`: the ability for `select()` to return a `ResultSet` object that upon iteration
+  will return a `RowGateway` instance for each row.
+
+    ```php
+    $table   = new TableGateway('artist', $adapter, new Feature\RowGatewayFeature('id'));
+    $results = $table->select(['id' => 2]);
+
+    $artistRow       = $results->current();
+    $artistRow->name = 'New Name';
+    $artistRow->save();
+    ```

+  supported PHP version.
+- [#51](https://github.com/zendframework/zend-stdlib/pull/51) adds a migration
+  document from v2 to v3. Hint: if you use hydrators, you need to be using
+  zend-hydrator instead!
+- [#51](https://github.com/zendframework/zend-stdlib/pull/51) adds automated
+  documentation builds to gh-pages.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- [#33](https://github.com/zendframework/zend-stdlib/pull/33) - removed
+  deprecated classes
+  - *All Hydrator classes* see #22.
+  - `Zend\Stdlib\CallbackHandler` see #35
+- [#37](https://github.com/zendframework/zend-stdlib/pull/37) - removed
+  deprecated classes and polyfills:
+  - `Zend\Stdlib\DateTime`; this had been deprecated since 2.5, and only
+    existed as a polyfill for the `createFromISO8601()` support, now standard
+    in all PHP versions we support.
+  - `Zend\Stdlib\Exception\InvalidCallbackException`, which was unused since #33.
+  - `Zend\Stdlib\Guard\GuardUtils`, which duplicated `Zend\Stdlib\Guard\AllGuardsTrait`
+    to allow usage with pre-PHP 5.4 versions.
+  - `src/compatibility/autoload.php`, which has been dprecated since 2.5.
+- [#37](https://github.com/zendframework/zend-stdlib/pull/37) - removed
+  unneeded dependencies:
+  - zend-config (used only in testing ArrayUtils, and the test was redundant)
+  - zend-serializer (no longer used)
+- [#51](https://github.com/zendframework/zend-stdlib/pull/51) removes the
+  documentation for hydrators, as those are part of the zend-hydrator
+  component.
+
+### Fixed
+
+- Nothing.
+
+## 2.7.4 - 2015-10-15
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- [#35](https://github.com/zendframework/zend-stdlib/pull/35) deprecates
+  `Zend\Stdlib\CallbackHandler`, as the one component that used it,
+  zend-eventmanager, will no longer depend on it starting in v3.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Nothing.
+
+## 2.7.3 - 2015-09-24
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- [#27](https://github.com/zendframework/zend-stdlib/pull/27) fixes a race
+  condition in the `FastPriorityQueue::remove()` logic that occurs when removing
+  items iteratively from the same priority of a queue.
+
+## 2.7.2 - 2015-09-23
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- [#26](https://github.com/zendframework/zend-stdlib/pull/26) fixes a subtle
+  inheritance issue with deprecation in the hydrators, and updates the
+  `HydratorInterface` to also extend the zend-hydrator `HydratorInterface` to
+  ensure LSP is preserved.
+
+## 2.7.1 - 2015-09-22
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- [#24](https://github.com/zendframework/zend-stdlib/pull/24) fixes an import in
+  `FastPriorityQueue` to alias `SplPriorityQueue` in order to disambiguate with
+  the local override present in the component.
+
+## 2.7.0 - 2015-09-22
+
+### Added
+
+- [#19](https://github.com/zendframework/zend-stdlib/pull/19) adds a new
+  `FastPriorityQueue` implementation. It follows the same signature as
+  `SplPriorityQueue`, but uses a performance-optimized algorithm:
+
+  - inserts are 2x faster than `SplPriorityQueue` and 3x faster than the
+    `Zend\Stdlib\PriorityQueue` implementation.
+  - extracts are 4x faster than `SplPriorityQueue` and 4-5x faster than the
+    `Zend\Stdlib\PriorityQueue` implementation.
+
+  The intention is to use this as a drop-in replacement in the
+  `zend-eventmanager` component to provide performance benefits.
+
+### Deprecated
+
+- [#20](https://github.com/zendframework/zend-stdlib/pull/20) deprecates *all
+  hydrator* classes, in favor of the new [zend-hydrator](https://github.com/zendframework/zend-hydrator)
+  component. All classes were updated to extend their zend-hydrator equivalents,
+  and marked as `@deprecated`, indicating the equivalent class from the other
+  repository.
+
+  Users *should* immediately start changing their code to use the zend-hydrator
+  equivalents; in most cases, this can be as easy as removing the `Stdlib`
+  namespace from import statements or hydrator configuration. Hydrators will be
+  removed entirely from zend-stdlib in v3.0, and all future updates to hydrators
+  will occur in the zend-hydrator library.
+
+  Changes with backwards compatibility implications:
+
+  - Users implementing `Zend\Stdlib\Hydrator\HydratorAwareInterface` will need to
+    update their `setHydrator()` implementation to typehint on
+    `Zend\Hydrator\HydratorInterface`. This can be done by changing the import
+    statement for that interface as follows:
+
+    ```php
+    // Replace this:
+    use Zend\Stdlib\Hydrator\HydratorInterface;
+    // with this:
+    use Zend\Hydrator\HydratorInterface;
+    ```
+
+    If you are not using imports, change the typehint within the signature itself:
+
+    ```php
+    // Replace this:
+    public function setHydrator(\Zend\Stdlib\Hydrator\HydratorInterface $hydrator)
+    // with this:
+    public function setHydrator(\Zend\Hydrator\HydratorInterface $hydrator)
+    ```
+
+    If you are using `Zend\Stdlib\Hydrator\HydratorAwareTrait`, no changes are
+    necessary, unless you override that method.
+
+  - If you were catching hydrator-generated exceptions, these were previously in
+    the `Zend\Stdlib\Exception` namespace. You will need to update your code to
+    catch exceptions in the `Zend\Hydrator\Exception` namespace.
+
+  - Users who *do* migrate to zend-hydrator may end up in a situation where
+    their code will not work with existing libraries that are still type-hinting
+    on the zend-stdlib interfaces. We will be attempting to address that ASAP,
+    but the deprecation within zend-stdlib is necessary as a first step.
+
+    In the meantime, you can write hydrators targeting zend-stdlib still in
+    order to guarantee compatibility.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Nothing.
+
+## 2.6.0 - 2015-07-21
+
+### Added
+
+- [#13](https://github.com/zendframework/zend-stdlib/pull/13) adds
+  `Zend\Stdlib\Hydrator\Iterator`, which provides mechanisms for hydrating
+  objects when iterating a traversable. This allows creating generic collection
+  resultsets; the original idea was pulled from
+  [PhlyMongo](https://github.com/phly/PhlyMongo), where it was used to hydrate
+  collections retrieved from MongoDB.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Nothing.
+
+## 2.5.2 - 2015-07-21
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.

+
+- [#9](https://github.com/zendframework/zend-stdlib/pull/9) fixes an issue with
+  count incrementation during insert in PriorityList, ensuring that incrementation only
+  occurs when the item inserted was not previously present in the list.
+
+## 2.4.4 - 2015-07-21
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
