ruff

Ruff is an extremely fast Python linter and code formatter, written in Rust. Ruff is a drop-in parity with Flake8, isort, and Black. Ruff aims to be orders of magnitude faster than alternative tools while integrating more functionality behind a single, common interface. Ruff documentation can be found here.

ruff can be used as a linter like this:

ruff check .

It can also fix automatically some of the errors, like this:

ruff check . --fix

In order to use ruff as a formatter one should run the following command:

ruff format .

All-‘n’-all ruff is super easy to use!

Note

ruff is now used and invoked automatically by tox. If you want to use ruff from tox then please use the following command:

tox -e ruff
