Trigger a PyPI and GitHub release everytime the package version is increased.

This support any PEP 518 compliant projects (flit, setuptools, poetry,...).

This action:

• Auto-detect when the package version is increased (in the pyproject.toml, module.__version__ when using flit, setup,...)
• Trigger a PyPI release of the project (build and publish)
• Auto-extract release notes from the CHANGELOG.md (if parse-changelog is true)
• Create the associated tag (e.g. v1.0.0) and GitHub release.

Example of usage:

name: Auto-publish

on: [push, workflow_dispatch]

jobs:
  # Auto-publish when version is increased
  publish-job:
    # Only publish on `main` branch
    if: github.ref == 'refs/heads/main'
    runs-on: ubuntu-latest
    permissions:  # Don't forget permissions
      contents: write

    steps:
    - uses: etils-actions/pypi-auto-publish@v1
      with:
        pypi-token: ${{ secrets.PYPI_API_TOKEN }}
        gh-token: ${{ secrets.GITHUB_TOKEN }}
        parse-changelog: true

You can also chain this job with your unittests to only trigger release if tests passes (needs: my-test-job).

• pypi-token: The PyPI token to publish the package. If missing, PyPI release is skipped.
• gh-token: GitHub action token. If missing, GitHub release is skipped.
• parse-changelog: If true, extract GitHub release notes from the CHANGELOG.md (assuming keep a changelog format)
• path (Optional): Directory of the project (containing the pyproject.toml). Default to ..
• pkg-name (Optional): Package name (auto-detected).
• git-ref (Optional): Git ref (e.g. SHA or tag). If git-ref: skip, the repository is not checked out (this can be used to manually checkout and update the repo before publishing).

• version: The detected version of the project (e.g. '1.0.0')
• is-released: Whether a new release was triggered ('true' / 'false')
