ruff-rev-sync-pre-commit

A pre-commit hook to automatically synchronize your Ruff version in .pre-commit-config.yaml with the version locked in uv.lock.

Purpose

When managing Python dependencies with uv, you have a specific version of ruff locked in your uv.lock file. However, the ruff-pre-commit hook in your .pre-commit-config.yaml is often updated independently, leading to version mismatches between your local environment/CI and the pre-commit hook.

This hook solves that problem by:

1. Reading the ruff version from your uv.lock file.
2. Checking the ruff-pre-commit revision in your .pre-commit-config.yaml.
3. Automatically updating the rev in .pre-commit-config.yaml to match the version in uv.lock.

Usage

Add this hook to your .pre-commit-config.yaml. It should run before the main ruff hook to ensure the version is correct.

repos:
  - repo: https://github.com/fllesser/ruff-rev-sync-pre-commit
    rev: v1.0.0
    hooks:
      - id: ruff-rev-sync

How it works

The hook runs a Python script that:

1. Locates uv.lock and .pre-commit-config.yaml in your project root.
2. Parses uv.lock to find the installed version of ruff.
3. Updates the rev field for https://github.com/astral-sh/ruff-pre-commit in .pre-commit-config.yaml to v{version}.

Requirements

• uv package manager (for uv.lock).
• ruff must be present in your uv.lock.
