Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

1.4.0 - 2024-03-15

Added

  • Added FileBuilder.WithMustExist() constraint.
  • Added Dir() builder for directory paths.

Changed

  • Bumped minimum Go version to v1.22.

1.3.0 - 2024-03-14

Added

  • Added StringBuilder.WithMinimumLength(), WithMaximumLength(), WithLength().
  • Added BytesBuilder.WithMinimumLength(), WithMaximumLength(), WithLength().

Fixed

  • Fixed wording of error message when a variable exceeds the maximum length.

1.2.1 - 2023-08-14

Changed

  • Dropped support for Go v1.19, which reached end-of-life on 2023-08-08
  • Removed use of the slices and maps packages from golang.org/x/exp. These package are not versioned and as such breaking changes can cause conflicts with other dependencies. The experimental constraints package is still used, with the expectation that these will always remain valid for use as type parameter constraints.

1.2.0 - 2023-06-12

Added

  • Added Registry and NewRegistry()
  • Added RegistryOption and WithDocumentationURL()

Changed

  • Changed WithRegistry() to accept a ferrite.Registry instead of the experimental variable.Registry type
  • Passing WithRegistry() to Init() is now additive, instead of replacing the default registry

Removed

  • Removed the experimental maybe and variable sub-packages

Fixed

  • Prevent registration of multiple environment variables with the same name

1.1.0 - 2023-06-06

Added

  • Added Binary() and BinaryAs() builders for binary variables
  • Added variable.LengthLimited schema for values that have minimum or maximum lengths

Changed

  • variable.String now implements the new LengthLimited interface
  • Rename the variable.[Min|Max]LengthError.String field to ViolatedSchema and change its type to LengthLimited

Removed

  • Removed "platform" examples from generated documentation. These are too opinionated and organization-specific to be included in every project's documentation. Instead, we will provide different export modes that can be used to generate Docker/Kubernetes/etc configurations, similar to the existing export/dotenv mode.

1.0.3 - 2023-04-20

Changed

  • export/dotenv mode now includes sensitive values in the output

1.0.2 - 2023-03-29

Fixed

  • Added export keyword to output of export/dotenv mode

Changed

  • Improve example values for File() builder

1.0.1 - 2023-03-28

Changed

  • Render a table of environment variables in Markdown documentation instead of bullet points
  • Simplify language in generated documentation

1.0.0 - 2023-03-17

  • No changes from v0.6.0.

0.6.0 - 2023-03-14

Added

  • Added SeeAlso() option
  • Added RelevantIf() option

Changed

  • [BC] SupersededBy() now accepts a single variable set and variadic options
  • [BC] Renamed Input to VariableSet
  • Refactored internal variable.Variable to allow for more flexible implementations

Removed

  • [BC] Removed SeeAlso() method from all builder types, use the new SeeAlso() option instead

0.5.0 - 2023-03-12

Added

  • Added SeeAlso() method to all builders, which links to another variable for documentation purposes
  • Added SupersededBy() option, which indicates which variables to use instead of a deprecated one
  • Added WithRegistry() option to allow registration of variables in custom variable registries

Changed

  • [BC] Floating point variables no longer accept NaN, +Inf or -Inf as valid values
  • [BC] Replaced WithConstraintFunc() with WithConstraint()
  • variable.Register() now directly accepts a Registry instead of using functional options

Removed

  • Removed variable.Option type and variable.WithRegistry() option

Fixed

  • Internal errors from strconv.ParseXXX() functions are no longer presented to the user verbatim

0.4.2 - 2023-03-11

Added

  • Added export/dotenv mode, which renders environment variables and their current values in dotenv format

Fixed

  • Fixed issue where durations were rendered with tailing zero-valued minute components

0.4.1 - 2023-03-10

Fixed

  • Markdown documentation is now rendered to STDOUT (instead of STDERR) as intended

0.4.0 - 2023-03-10

Added

  • Added Deprecated() method to all builders, which marks the variable as deprecated and warns the user if it is defined
  • Added StringBuilder.WithSensitiveContent(), which hides the variable value from console output and generated documentation
  • Added functional options to Init()

Changed

The following changes are technically not backwards compatible from a Go perspective, but under normal usage (as per the examples) they do not actually alter the usage of the Ferrite API.

  • [BC] NetworkPort() now returns a NetworkPortBuilder instead of StringBuilder
  • [BC] Required[T] and Optional[T] are now structs instead of interfaces
  • [BC] All builder types now use pointer receivers
  • [BC] Require() and Optional() methods on all builders now use distinct option types

0.3.6 - 2023-03-06

Fixed

  • Fixed schema rendering of URL variables in validation mode

Changed

  • Improved algorithm for choosing which example to show in generated usage documentation

0.3.5 - 2023-03-06

Fixed

  • Remove use of strings.CutPrefix() to maintain compatibility with Go v1.19

0.3.4 - 2023-03-05

Changed

  • Generate Markdown documentation for the syntax of integers, floating-point values, URLs and network ports
  • Other general improvements to generated Markdown documentation

Fixed

  • Trailing zeroes are no longer rendered on floating point values

0.3.3 - 2023-03-03

Added

  • Add URL()
  • Generated Markdown documentation now indicates whether example values are normative or non-normative
  • Generated Markdown documentation now describes the format of duration variables

0.3.2 - 2022-11-30

Added

  • Add Float()
  • Add File()
  • Add DurationBuilder.WithMinimum() and WithMaximum()
  • Add SignedBuilder.WithMinimum() and WithMaximum()
  • Add UnsignedBuilder.WithMinimum() and WithMaximum()

0.3.1 - 2022-08-24

Added

  • Add NetworkPort()

0.3.0 - 2022-08-15

Added

  • Added support for generating markdown documentation

0.2.0 - 2022-08-08

This is a fairly substantial refactor from the initial prototype, though usage is largely unchanged. See the examples for details.

The two most important changes in usage are:

  • ValidateEnvironment() has been renamed to Init()
  • Either Optional() or Required() must be called at the end of a builder chain

0.1.0 - 2022-08-03

  • Initial release
