ray-project Lint Modified Files
Run pre-commit on the files you changed:
pre-commit run --files $(git diff --name-only HEAD)
pre-commit run without --files only operates on staged files, so pass the
modified file list explicitly.
If pre-commit is not installed:
pip install -c python/requirements_compiled.txt pre-commit && pre-commit install
Handling remaining errors
Pre-commit auto-fixes simple issues (formatting, long lines, unused imports). Review any remaining errors — these typically need code changes such as adding a missing import, resolving a name conflict, or restructuring logic. Fix them by editing the source code directly.
Use # noqa only for false positives that cannot be resolved by changing the code,
and include the rule code and reason: # noqa: E501 — URL cannot be split.
Exclusions
pyproject.toml lists files in per-file-ignores and extend-exclude. When the PR
modifies a file that is on one of these lists, fix the lint issues in your changes
and consider removing the file from the list. Leave exclusion entries for files
outside the PR scope untouched.
