EasyBuild.Parser

Common commit parser library used by other EasyBuild tools like EasyBuild.ChangelogGen or EasyBuild.CommitLinter.

It aims to provide helpful contextual error messages like:

Example of error messages:

Invalid commit message format.

Expected a commit message with the following format: '<type>[optional scope]: <description>'.

Where <type> is one of the following:

- feat: A new feature
- fix: A bug fix
- ci: Changes to CI/CD configuration
- chore: Changes to the build process or auxiliary tools and libraries such as documentation generation
- docs: Documentation changes
- test: Adding missing tests or correcting existing tests
- style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
- refactor: A code change that neither fixes a bug nor adds a feature

Example:
-------------------------
feat: some description
-------------------------

or

Unkonwn tag(s) in the footer.

Received:

- some-tag

But allowed tags are:

- converter
- web

Usage

open EasyBuild.CommitParser
open EasyBuild.CommitParser.Types

let commitText = "..."

// If you need the commit message information
Parser.tryParseCommitMessage CommitParserConfig.Default commitText
// > it: Result<CommitMessage,string>

// If you just want to validate the commit message
Parser.tryValidateCommitMessage CommitParserConfig.Default commitText
// > it: Result<unit,string>

For the configuration, you can use the default configuration or provide a custom one.

open EasyBuild.CommitParser.Types

// Default configuration
CommitParserConfig.Default

// My custom configuration
{
    Types =
        [
            // ...
        ]
    Tags =
        [
            // ...
        ] |> Some
}

// You can also use a configuration file by passing the JSON content to the included Decoder
open Thoth.Json.Newtonsoft

let configurationJson = "..."

match Decode.fromString CommitParserConfig.decoder configContent with
| Ok config -> config
| Error error ->
    failwithf "Error while parsing the configuration file: %s" error

Commit Format

[!NOTE] EasyBuild.CommitParser format is based on Conventional Commits

It add a special Tag footer, allowing it to be used in a mono-repo context.

Tools like EasyBuild.ChangelogGen can use the tag to filter the commits to include in the changelog.

<type>[optional scope][optional !]: <description>

[optional body]

[optional footer]

• [optional body] is a free-form text.

  This is a single line body.
  

  This is a
  
  multi-line body.
  

• [optional footer] is inspired by git trailer format key: value but also allows key #value

  BREAKING CHANGE: <description>
  Signed-off-by: Alice <alice@example.com>
  Signed-off-by: Bob <bob@example.com>
  Refs #123
  Tag: cli
  

  💡 The Tag footer can be provided multiple times.

Configuration

EasyBuild.CommitParser comes with a default configuration to validate your commit.

The default configuration allows the following commit types with no tags required:

• feat - A new feature
• fix - A bug fix
• ci - Changes to CI/CD configuration
• chore - Changes to the build process or auxiliary tools and libraries such as documentation generation
• docs - Documentation changes
• test - Adding missing tests or correcting existing tests
• style - Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
• refactor - A code change that neither fixes a bug nor adds a feature

If needed, you can provide a custom configuration either by code directly or by using a configuration file using JSON format.

Configuration File Format

The configuration file is a JSON file with the following properties:

types

• Required: ✅
• Type: { name: string, description?: string, skipTagFooter?: bool } []

List of accepted commit types.

tags

• Required: ❌
• Type: string []

List of accepted commit tags.
