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
- perf: A code change that improves performance
- revert: Reverts a previous commit
- build: Changes that affect the build system or external dependencies
Example:
-------------------------
feat: some description
-------------------------

or

Unkonwn tag(s) in the footer.
Received:

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

<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

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
• perf - A code change that improves performance
• revert - Reverts a previous commit
• build - Changes that affect the build system or external dependencies

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.
