Version control integration

Use pre-commit. Once you have it installed, add this to the .pre-commit-config.yaml in your repository:

repos:
  - repo: https://github.com/psf/black
    rev: 21.11b0
    hooks:
      - id: black
        # It is recommended to specify the latest version of Python
        # supported by your project here, or alternatively use
        # pre-commit's default_language_version, see
        # https://pre-commit.com/#top_level-default_language_version
        language_version: python3.9

Feel free to switch out the rev value to something else, like another tag/version or even a specific commit. Although we discourage the use of branches or other mutable refs since the hook won’t auto update as you may expect.

If you want support for Jupyter Notebooks as well, then replace id: black with id: black-jupyter (though note that it’s only available from version 21.8b0 onwards).
