Provide a pre-commit hook for hatch fmt

[ghisvail]

I am using Hatch for project management in my Python projects, and recently adopted hatch fmt instead of directly calling Ruff previously. I also use pre-commit in my CI workflows to run several linters project-wide. Right now, I use Hatch for formatting locally and Ruff in the CI run of pre-commit.

Ruff was recently updated (version 0.1.14) and its config now produces a different outcome than Hatch, since the latter depends on an older version (version 0.1.8 if I understood correctly). I can force Hatch to use an updated version of Ruff with:

# pyproject.toml

[tool.hatch.envs.hatch-static-analysis]
dependencies = ["ruff==0.1.14"]

so that both Ruff and Hatch are in agreement. It's not awful, but there is now a redundancy between Hatch's configuration and Ruff's pre-commit setup.

Instead, I was wondering whether a pre-commit hook could be introduced for Hatch to just run hatch fmt, with or without an updated version of Ruff based on the dependencies setting above.

Cheers, and thanks for your wonderful work on Hatch.

I noticed this issue with pre-commit and was wondering maybe you can replace the ruff pre-commit hook with the a local that calls Hatch instead of Ruff?

I tried this and it worked for my use case. ref

pre-committ-config.yaml

repos:
  - repo: local
    hooks:
      - id: ruff-format-hatch-settings
        name: hatch-ruff
        language: system
        entry: hatch fmt
        pass_filenames: false
        verbose: true

I am open to this but do not have any idea where to begin as I do not use pre-commit.

Perhaps this article is useful?
