Thank you very much for your measurements. My impression is also that it would take really large projects with many checks for me to deviate from the reference implementation.

I did my performance tests with hyperfine:
hyperfine \
--prepare 'rm -rf ~/.cache/prek/ && rm -rf ~/.cache/pre-commit && rm -rf ~/.cache/uv' \
'prek install-hooks' \
'pre-commit install-hooks'

No, even when running the pre-commit hook, execution is more than twice as fast.

The latest uv release (0.8.13) introduced the experimental uv format. It calls Ruff’s formatter to automatically style your code: github.com/astral-sh/uv.... And you can use [tool.ruff] for both entry points.

Thank you for your reply – I was a little confused at first.

Veit Schiele @veit-schiele.de · Aug 21

Thank you for your enquiry. I was initially confused, as PEP 639 only allowed SPDX classifiers for licences. "Private :: Do Not Upload" in the trove classifiers continues to prevent uploads.
