This repository contains GitHub Actions workflows that automate the process of creating GitHub releases and publishing a Python package to PyPI when a new version is specified in the pyproject.toml file.

Workflows

Create Release if New Version (create_release_if_new_version.yml)

This workflow is responsible for creating a GitHub release when a new version of the Python package is specified in the pyproject.toml file. The workflow performs the following steps:

• Gets triggered on pushes to the main branch.
• Checks out the repository code.
• Sets up Python.
• Installs necessary Python packages (toml and packaging) required to read pyproject.toml and parse versions.
• Retrieves the current version from pyproject.toml.
• Fetches all tags to check against the latest tag.
• Checks if the version is incremented compared to the latest tag.
• If the version is incremented, it creates a new git tag.
• Pushes the new git tag to the repository.
• Creates a new GitHub release with the new tag.

Publish Python Package to PyPI (publish-to-pypi.yml)

This workflow is responsible for building the Python package and publishing it to PyPI. The workflow performs the following steps:

• Gets triggered by the successful completion of the "Create Release if New Version" workflow.
• Checks out the repository code.
• Sets up Python.
• Installs dependencies required to build and publish the package (build and twine).
• Builds the Python package.
• Publishes the package to PyPI or TestPyPI based on the configuration.

Setup

• Configure the following secrets in your GitHub repository settings under "Secrets":

  • PYPI_API_TOKEN - Your API token for PyPI (production).
  • TEST_PYPI_API_TOKEN - Your API token for TestPyPI (testing).

• Ensure that your project contains a valid pyproject.toml file with the package version specified.

• Push your changes to the main branch.

Usage

• Make changes to your Python package.

• Update the version in pyproject.toml according to semantic versioning.

• Push the changes to the main branch.

• The "Create Release if New Version" workflow will run. If the version is incremented, a GitHub release will be created, and the "Publish Python Package to PyPI" workflow will be triggered.

• The "Publish Python Package to PyPI" workflow will build and publish your package to the configured PyPI repository (TestPyPI or production PyPI).

Note

• It is important to increment the version in pyproject.toml according to semantic versioning standards for the workflow to create a release.

• Ensure you have properly configured the PYPI_API_TOKEN and TEST_PYPI_API_TOKEN secrets in your GitHub repository.

• When Github Repo is Protected, you need to allow GITHUB_TOKEN Read and Write access to the repository. Go to the repository Settings > Actions > General > Workflow Permissions > Allow Read and Write permissions.
