GitHub Action: Release Generator

This GitHub Action automates the process of generating releases in your GitHub repository. It creates a new release based on the latest version tag, increments the version number following semantic versioning, and includes commit messages in the release notes. You can also add a custom description to the release.

Features

• Automatic Versioning: Increments the patch version automatically following semantic versioning.
• Commit-Based Changelog: Generates release notes based on commit messages since the last release.
• Custom Release Description: Allows for additional custom release notes to be included.
• Fully Dockerized: Runs in a Docker container with a Python environment.

Example Usage

Here’s an example of how to use this GitHub Action in a workflow:

name: Release Workflow

env:
  INCREMENTAL_TYPE: patch

on:
  push:
    branches:
      - main

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Generate Release
        uses: ADORSYS-GIS/[email protected]
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          add_description: "This is an additional note for the release."
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          GITHUB_USERNAME: ${{ secrets.GITHUB_USERNAME }}
          REPO_NAME: ${{ secrets.REPO_NAME }}
          INCREMENTAL_TYPE: ${{ env.INCREMENTAL_TYPE }}

How It Works

1. Versioning: The action fetches the latest release or tag from your repository. If no releases or tags are found, it starts from version 0.0.0 and increments to 0.0.1.

2. Commit Messages: It gathers all commit messages since the last release/tag and includes them in the release notes.

3. Release Notes: The commit messages are grouped under the "Changes in this release" section. If provided, the content of add_description is added as additional notes.

4. Release Creation: The action creates a new release on GitHub with the incremented version and the generated release notes.

Local Development

To test or modify this action locally, you can build and run the Docker container manually:

docker build -t release-generator .
docker run --rm -e GITHUB_TOKEN=your-token -e ADD_DESCRIPTION="This is a test release" -e REPO_NAME=your_repo_name -e GITHUB_USERNAME=your_github_username -e INCREMENT_TYPE=major release-generator
