# black-pre-commit-mirror

Using this repository in your pre-commit config makes Black twice as fast.

## Explanation

pre-commit installs hooks by cloning the repo you specify and installing from source, as opposed to
installing Black from [PyPI][1].

However, Black uploads [mypyc][2]-accelerated extension modules to PyPI that make Black about twice
as fast. Using this mirror in the repo field of your pre-commit config instead of
https://github.com/psf/black tricks pre-commit into installing these prebuilt accelerated wheels
instead, where possible.

The trick is very simple: just declare Black as a dependency of this fake black-pre-commit-mirror
project. While pre-commit will install black-pre-commit-mirror from source, it will still install
its dependencies from PyPI.

## More

For example `pre-commit` configs, please see the [Black VCS integration docs][3]
