update-mypy-hook 0.3.0

Update the additional dependencies of mypy pre-commit hook from uv.lock

Update mypy pre-commit hook

This script uses uv to update the additional_dependencies of the mypy pre-commit hook.

With uv export it will generate a list of all dependencies required to run mypy. By default, it assumes that an uv dependency group, called mypy, exists and contains all additional dependencies (besides the project dependencies) to successfully run type checking. The group(s) may only contain the direct dependencies. Transitive dependencies are derived by uv automatically.

The dependency group(s) can be overwritten by -g/--group option.

Installation

If you have installed uv on your machine or is already part of your dependencies you can run

pip install update-mypy-hook

or with uv

uv add update-mypy-hook --group dev

If uv is not part of your setup, use the extra

pip install update-mypy-hook[uv]

Using update-mypy-hook

Run in your python project root folder
