pre-commit-uv
Use uv to create virtual environments and install packages for pre-commit.
Installation
With pipx:
pipx install pre-commit
pipx inject pre-commit pre-commit-uv
With uv:
uv tool install pre-commit --with pre-commit-uv --force-reinstall
Why?
Compared to upstream pre-commit will speed up the initial seed operation. In general, upstream recommends caching the
pre-commit cache, however, that is not always possible and is still helpful to have a more performant initial cache
creation., Here's an example of what you could expect demonstrated on this project's own pre-commit setup (with a hot
uv cache):
❯ hyperfine 'pre-commit install-hooks' 'pre-commit-uv install-hooks'
Benchmark 1: pre-commit install-hooks
Time (mean ± σ): 54.132 s ± 8.827 s [User: 15.424 s, System: 9.359 s]
Range (min … max): 45.972 s … 66.506 s 10 runs
Benchmark 2: pre-commit-uv install-hooks
Time (mean ± σ): 41.695 s ± 7.395 s [User: 7.614 s, System: 6.133 s]
Range (min … max): 32.198 s … 58.467 s 10 runs
Summary
pre-commit-uv install-hooks ran 1.30 ± 0.31 times faster than pre-commit install-hooks
Configuration
Once installed will use uv out of box, however the DISABLE_PRE_COMMIT_UV_PATCH environment variable if is set it
will work as an escape hatch to disable the new behavior.
To avoid interpreter startup overhead of the patching, we only perform this when we detect you calling pre-commit.
Should this logic fail you can force the patching by setting the FORCE_PRE_COMMIT_UV_PATCH variable. Should you
experience this please raise an issue with the content of the sys.argv. Note that DISABLE_PRE_COMMIT_UV_PATCH will
overwrite this flag should both be set.
