calver-auto-release 1.0.2

Automatically create GitHub releases using Calendar Versioning (CalVer)

calver-auto-release 🏷️

🏷️ Automatically create GitHub releases using Calendar Versioning (CalVer) on every commit.

This tool is perfect for:

• 📦 Packages where users should always use the latest version
• 🔬 Research software where releases are not tied to specific feature completions
• 🔄 Projects with continuous deployment where each merge to main is a potential release
• 🤖 Automating away the decision of "when should we release?"

By automatically creating a release on every commit to your main branch, you ensure that:

1. Users always have access to the latest changes
2. Version numbers clearly indicate when changes were made
3. Each change is properly documented through commit messages
4. The release process is completely automated

[!NOTE] For the best experience, we recommend using squash merges for your Pull Requests. This ensures that:

• Each release corresponds to one logical change
• Release notes are clean and meaningful
• The git history remains linear and easy to understand

Configure this in your GitHub repository settings under "Pull Requests" → "Allow squash merging" and uncheck other merge methods.

Usage

GitHub Action

Add this to your workflow file (e.g., .github/workflows/release.yml):

name: Create Release
on:
  push:
    branches:
      - main
jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      # Create release with CalVer
      - uses: basnijholt/calver-auto-release@v1
        id: release
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          # Optional: custom configuration
          skip_patterns: "[skip release],[no-release]"
          footer: "Custom footer text"

      # Optional: publish to PyPI
      # Only run if a new version was created
      - name: Build package
        if: steps.release.outputs.version != ''
        run: |
          python -m pip install build
          python -m build

      # Option 1: Publish with official PyPA action
      - name: Publish package distributions to PyPI
        if: steps.release.outputs.version != ''
        uses: pypa/gh-action-pypi-publish@release/v1

      # Option 2: Publish with twine
      # - name: Publish package distributions to PyPI
      #   if: steps.release.outputs.version != ''
      #   env:
      #     TWINE_USERNAME: __token__
      #     TWINE_PASSWORD: ${{ secrets.PYPI_TOKEN }}
      #   run: |
      #     python -m pip install twine
      #     twine upload dist/*

The action creates a new release with CalVer versioning, and you can optionally add your preferred method for publishing to PyPI or any other post-release tasks.

[!IMPORTANT] The secrets.GITHUB_TOKEN variable is automatically populated (see docs). However, releases created using GITHUB_TOKEN will not trigger other workflows that run on the release event. If you need to trigger other workflows when a release is created, you'll need to:

1. Create a Personal Access Token (PAT) with contents: write permissions at https://github.com/settings/tokens
2. Add it to your repository secrets (e.g., as PAT)
3. Use it in the workflow:

   - uses: basnijholt/calver-auto-release@v1
     with:
       github_token: ${{ secrets.PAT }}  # Instead of secrets.GITHUB_TOKEN
   

CLI Usage

# Basic usage
calver-auto-release --repo-path /path/to/repo

# Dry run (show what would happen without creating the release)
calver-auto-release --repo-path /path/to/repo --dry-run

# Custom skip patterns
calver-auto-release --repo-path /path/to/repo --skip-pattern "[no-release]" --skip-pattern "[skip]"

Python API

from calver_auto_release import create_release

# Basic usage
create_release()  # Uses current directory

# With custom configuration
create_release(
    repo_path="/path/to/repo",
    skip_patterns=["[skip]", "[no-release]"],
    footer="\nCustom footer text",
    dry_run=True,  # Show what would happen without creating the release
)

Release Notes Format

The generated release notes will have this format:

🚀 Release YYYY.MM.PATCH

📝 This release includes the following changes:

- First commit message
- Second commit message
- etc.

🙏 Thank you for using this project! Please report any issues or feedback on the GitHub repository

Requirements

• Git repository with an 'origin' remote configured
• Python 3.10 or higher
• Git command-line tools installed

Installation

Install using pip:

pip install calver-auto-release

Or using uv:

uv pip install calver-auto-release

Configuration

Skip Release Patterns

You can skip creating a release by including these patterns in your commit message:

• [skip release]
• [pre-commit.ci]
• ⬆️ Update

Version Format

The version format follows CalVer: YYYY.MM.PATCH

• YYYY: Current year
• MM: Current month
• PATCH: Incremental number, resets when year or month changes

Custom Footer

You can customize the footer text that appears at the end of each release note:

create_release(
    footer="\nCustom footer text for all releases"
)

Or via CLI:

calver-auto-release --footer "Custom footer text"

Or in the GitHub Action:

- uses: basnijholt/calver-auto-release@v1
  with:
    github_token: ${{ secrets.GITHUB_TOKEN }}
    footer: "Custom footer text"
