Release-a-Changelog action

This GitHub action creates a release based on your CHANGELOG.md file. You must use Keep a Changelog format or this will not work.

A release is created every time a new version header is added to your CHANGELOG.md file. The content of the release is the entire text up to the next version header (the previously released version).

## [<version>] - yyyy-mm-dd
<content>

## [<previous version>] - yyyy-mm-dd

Installation

Add the following to a new .github/workflows/release_a_changelog.yml file (or as part of your existing workflow):

name: Release a Changelog

on:
  push:
    branches:
      - master

jobs:
  release_a_changelog:
    name: Release a Changelog
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4
      - name: Release a Changelog
        uses: rasmus-saks/[email protected]
        with:
          github-token: '${{ secrets.GITHUB_TOKEN }}'
          # Optional - path to your changelog file. Defaults to 'CHANGELOG.md'
          path: 'path/to/my/CHANGELOG.md'
          # Optional - format of the release title. Defaults to '{version}'
          title-template: 'My Project {version}'
          # Optional - format of the release tag. Defaults to '{version}'
          tag-template: 'my-project-{version}'

⚠️ Make sure you have a checkout action before release-a-changelog, otherwise it won't be able to read your CHANGELOG.md file

Multi-project setup

Use the title-template and tag-template inputs to define the format of the release title and tag for each separate project in your repository. Use {version} as a placeholder for the version number.

⚠️ Make sure the tag-template is unique for each project in the repository, otherwise releases may clash with each other.
