Linting with Ruff: the Python linter built with Rust

Ruff is a Python linter and code formatter that stands out for its efficiency and speed, being built in Rust, which allows it to handle large projects quickly and effectively. Unlike other tools, Ruff combines linting and formatting into one package, supporting over 800 lint rules inspired by popular linters like Flake8 and Pylint, thus facilitating an easy transition without extensive reconfiguration. Its installation and configuration are straightforward, allowing developers to set up linting and formatting rules via the pyproject.toml or ruff.toml files. Benchmark tests reveal that Ruff significantly outperforms competitors like Flake8 and Black, especially in larger codebases, demonstrating near-instantaneous performance. Despite being relatively new, released in 2022, Ruff has gained rapid adoption and is used by major projects such as Apache Airflow and FastAPI, indicating a promising future for community support and further development.
