`Ruff <https://github.com/charliermarsh/ruff>`_ is an extremely fast Python
linter and formatter, written in Rust. It can process all of mozilla-central in
under a second, and implements rule sets from a large array of Python linters
and formatters, including:
* flake8 (pycodestyle, pyflakes and mccabe)
* isort
* pylint
* pyupgrade
* and many many more!
Run Locally
-----------
The mozlint integration of ruff can be run using mach:
.. parsed-literal::
$ mach lint --linter ruff <file paths>
Configuration
-------------
Ruff is configured in the root `pyproject.toml`_ file. Additionally, ruff will
pick up any ``pyproject.toml`` or ``ruff.toml`` files in subdirectories. The
settings in these files will only apply to files contained within these
subdirs. For more details on configuration discovery, see the `configuration
documentation`_.
For a list of options, see the `settings documentation`_.
