Issues, bugs, and requests

We welcome contributions and feedback. Please file a request in our issue tracker and we'll take a look.

Dev env installation

A TLDR version follows:

  1. Ensure you have Ruby installed; you need version 2.2.2 or later:
    • ruby --version
  2. Ensure you have Bundler installed; if not install with:
    • gem install bundler -v 2.0.1
  3. Install all dependencies:
    • bundle install

If you see this error:

ERROR: Failed to build gem native extension

then you'll need change your ruby version by using (with X.X version asked in error message):

sudo apt-get install rubyX.X-dev

If you see nokogiri installation error, make sure you got required dependencices:

    sudo apt-get install libxslt-dev libxml2-dev

View Site in dev mode

 bundle exec jekyll serve

or

jekyll serve -w --force_polling

Testing

rake checklinks

IMPORTANT Need to run the website in another process

Some form of broken links prevention is done automatically by rake checklinks on every commit (through tool/travis.sh). But this will not see any Firebase redirects (rake checklinks does not run the Firebase server) and it will not check incoming links.

Before we can move the more complete automated linkcheck solution from dartlang.org, we recommend manually running the following.

  • First time setup:

    pub global activate linkcheck npm install -g superstatic

  • Start the localhost Firebase server:

    superstatic --port 3474

  • Run the link checker:

    linkcheck :3474

Even better, to check that old URLs are correctly redirected:

linkcheck :3474 --input tool/sitemap.txt

Automatic deployment

Merge your work on branch deploy, and push it.

You need to make sure than the tests pass.

We have set up Travis to deploy on commit on the git branch deploy.

Manual deployment

Generate static site:

bundle exec jekyll build # build goes to ./_site

Deploy to Firebase hosting

firebase deploy -p ./_site

Adding next/previous page links

If you have a document that spans multiple pages, you can add next and previous page links to make navigating these pages easier. It involves adding some information to the front matter of each page, and including some HTML.

---
layout: tutorial
title: "Constraints"

permalink: /tutorials/layout/constraints.html
prev-page: /tutorials/layout/properties.html
prev-page-title: "Container Properties"
next-page: /tutorials/layout/create.html
next-page-title: "Create a Layout"
---

{% include prev-next-nav.html %}

{:toc}

<!-- PAGE CONTENT -->

{% include prev-next-nav.html %}

Omit the "prev-page" info for the first page, and the "next-page" info for the last page.

Syntax highlighting

The website uses prism.js for syntax highlighting. This section covers how to use syntax highlighting, and how to update our syntax highlighter for new languages.

Supported languages

This website can syntax highlight the following languages:

  • shell
  • dart
  • html
  • css
  • javascript
  • java
  • objectivec
  • swift
  • go
  • php
  • python
  • ruby

Using syntax highlighting

The easiest way to syntax highlight a block of code is to wrap it with triple backticks followed by the language.

Here's an example:

class SomeCode {
  String name;
}

See the list of supported languages above for what to use following the first triple backticks.

Adding more languages for syntax highlighting

The website uses a custom build of prism, which includes only the languages the website requires. To improve load times and user experience, we do not support every language that prism supports.

To add a new language for syntax highlighting, you will need to generate a new copy of the prism.js file.

Follow these steps to generate a new copy of prism.js:

  • Open js/prism.js
  • Copy the URL in the comment of the first line of the file
  • Paste it into a browser window/tab
  • Add the new language that you wish to syntax highlight
  • DO NOT change the other plugins, languages, or settings
  • Download the generated JavaScript, and use it to replace js/prism.js
  • Download the generated CSS, and use it to replace _sass/_prism.scss

Including a region of a file

You can include a specific range of lines from a file:

{% include includelines filename=PATH start=INT count=INT %}

PATH must be inside of _include. If you are including source code, place that code into _include/code to follow our convention.
