Version control integration

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

  - repo:
    rev: stable
      - id: black
        language_version: python3.6

Then run pre-commit install and you’re ready to go.

Avoid using args in the hook. Instead, store necessary configuration in pyproject.toml so that editors and command-line usage of Black all behave consistently for your project. See Black’s own pyproject.toml for an example.

If you’re already using Python 3.7, switch the language_version accordingly. Finally, stable is a branch that tracks the latest release on PyPI. If you’d rather run on master, this is also an option.
