I'm mainly just a hobby programmer but I'm trying to up my CI/CD game. I'm comfortable with mypy and pytest and I'm now looking to integrate ruff. Obviously I know how to launch it, but I'm confused about how its used in practice.

For example, running as:

ruff check
ruff format --check

And then manually addressing objections? Or, do you just let ruff make its changes:

ruff check --fix
ruff format

...or something else entirely? Thanks.

Hey All,

Just wanted to share my latest blog about my favorite pre-commit hooks that help with writing quality code.

What are your favorite hooks??

TL;DR: Auto-sync your pre-commit hook versions with uv.lock

# Add this to .pre-commit-config.yaml
- repo: https://github.com/tsvikas/sync-with-uv
  rev: v0.3.0
  hooks:
    - id: sync-with-uv

Benefits:

• Consistent tool versions everywhere (local/pre-commit/CI)

• Zero maintenance

• Keeps pre-commit's isolation and caching benefits

• Works with pre-commit.ci

The Problem

PEP 735 recommends putting dev tools in pyproject.toml under [dependency-groups]. But if you also use these tools as pre-commit hooks, you get version drift:

• uv update bumps black to 25.1.0 in your lockfile

• Pre-commit still runs black==24.2.0

• Result: inconsistent results between local tool and pre-commit.

What My Project Does

This tool reads your uv.lock and automatically updates .pre-commit-config.yaml to match.

Works as a pre-commit (see above) or as a one-time run: uvx sync-with-uv

Target Audience

developers using uv and pre-commit

Comparison 

❌ Using manual updates?

• Cumbersome

• Easy to forget

❌ Using local hooks?

- repo: local
  hooks:
    - id: black
      entry: uv run black

• Breaks pre-commit.ci

• Loses pre-commit's environment isolation and tool caching

❌ Removing the tools from pyproject.toml?

• Annoying to repeatedly type pre-commit run black

• Can't pass different CLI flags (ruff --select E501 --fix)

• Some IDE integration breaks (when it requires the tool in your environment)

• Some CI integrations break (like the black action auto-detect of the installed version)

Similar tools:

• sync_with_poetry - Poetry version

• sync-pre-commit-lock - PDM/Poetry plugin
