About
Check your Python code for errors and style problems, and format it, with a single tool. Ruff can fix many issues automatically, such as removing unused imports, and it reads its settings from pyproject.toml.
It is written in Rust and installs with pip. Over 900 built-in rules include reimplementations of popular Flake8 plugins, and it can stand in for Flake8, Black and isort. Caching skips unchanged files, and configuration can cascade through a monorepo. An official VS Code integration is available.
Highlights
- Lints and formats Python in one tool
- Over 900 built-in rules with automatic fixes
- Can replace Flake8, Black and isort
Who it's for
