ChangeLog

GitHub Action for generating change logs. Fully based on TypeScript so will work on multiple targets not just linux. Based on the azure devops task.

It is slightly different from the azure in terms of it will detect different prefixes and place related commits under group headings.

Example workflow - create a release

Generate changelog from git commits and use it as the body for the GitHub release.

on:
  push:
    # Sequence of patterns matched against refs/tags
    tags:
      - 'v*' # Push events to matching v*, i.e. v1.0, v20.15.10

name: Create Release

jobs:
  build:
    name: Create Release
    runs-on: ubuntu-latest
    steps:
    - name: Checkout code
        uses: actions/checkout@v2
        with:
          fetch-depth: 0
    - name: Changelog
      uses: glennawatson/ChangeLog@v1
      id: changelog

    - name: Create Release
      uses: actions/create-release@v1
      env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} # This token is provided by Actions, you do not need to create your own token
      with:
          tag_name: ${{ github.ref }}
          release_name: Release ${{ github.ref }}
          body: |
            ${{ steps.Changelog.outputs.changelog }}

Commit Prefixes

One is a special case for Dependabot, if the author of the commit is @dependabot-preview then Dependencies will be the group header.

Prefix	Release Note Header
dep	Dependencies
dependency	Dependencies
feature	Features
feat	Features
docs	Documentation
style	Style Changes
perf	Performance
test	Test
refactor	Refactoring
housekeeping	Housekeeping
fix	Fixes
bug	Bug Fixes

Inputs

All inputs are optional.

Input	Description	Default Value
token	Personal access token (PAT) used to fetch the repository. The PAT is configured with the local git config, which enables your scripts to run authenticated git commands. The post-job step removes the PAT. We recommend using a service account with the least permissions necessary. Also when generating a new PAT, select the least scopes necessary.Learn more about creating and using encrypted secrets	${{ github.token }}
ref	The branch, tag or SHA to checkout. When checking out the repository that triggered a workflow, this defaults to the reference or SHA for that event. Otherwise, uses the default branch.
repository	description: 'Repository name with owner. For example, glennawatson/ChangeLog'	${{ github.repository }}

Outputs

Output	Description
changelog	The generated change log
