Setting up pre-commit in a new project

Links

• pre-commit

Instructions

• Install with pip install pre-commit in your local dev environment. Even though I work in Docker environments, I still use a virtualenv so I don't need to rebuild a container every time I run pre-commit.
• Add a .pre-commit-config.yaml file
• Add the things you want linted to that config file
• The first time you run pre-commit, run pre-commit run --all-files if you want to lint your whole codebase at once
• After that, run pre-commit run and only the files you changed will be linted

My config file

• adamchainz/blacken-docs: Run `black` on python code blocks in documentation files
