An example Python project

Sample PyPI package + GitHub Actions + Versioneer

This template aims to automate the tedious and error-prone steps of tagging/versioning, building and publishing new package versions. This is achieved by syncing git tags and versions with Versioneer, and automating the build and release with GitHub Actions, so that publishing a new version is as painless as:

$ git tag vX.Y.Z && git push --tags

The following guide assumes familiarity with setuptools and PyPI. For an introduction to Python packaging, see the references at the bottom.

How to use this template

1. Click on the Use this template button to get a copy of this repository.

2. Rename src/sample_package folder to your package name — src/ is where your package must reside.

3. Go through each of the following files and rename all instances of sample-package or sample_package to your package name. Also update the package information such as author names, URLs, etc.

   1. setup.py
   2. pyproject.toml
   3. __init__.py

4. Install versioneer and tomli, and run versioneer:

   $ pip install tomli
   $ pip install versioneer
   $ versioneer install
   

   Then commit the changes produced by versioneer. See here to learn more.

5. Setup your PyPI credentials. See the section Saving credentials on Github of this guide. You should use the variable names TEST_PYPI_API_TOKEN and PYPI_API_TOKEN for the TestPyPI and PyPI tokens, respectively. See .github/workflows/release.yaml.

You are all set! It should now be possible to run git tag vX.Y.Z && git push --tags to automatically version, build and publish a new release to PyPI.

Finally, it is a good idea to configure tag protection rules in your repository.
