.. index:: linters
flake8
ruff
------
To run flake8: ::
Ruff is a Python linter and code formatter, written in Rust.
It is a aggregation of flake8, pylint, pyupgrade and many more.
$ flake8
Ruff comes with a linter (``ruff check``) and a formatter (``ruff format``).
The linter is a wrapper around flake8, pylint, and other linters,
and the formatter is a wrapper around black, isort, and other formatters.
The config for flake8 is located in setup.cfg. It specifies:
To run ruff without modifying your files: ::
* Set max line length to 120 chars
* Exclude ``.tox,.git,*/migrations/*,*/static/CACHE/*,docs,node_modules``
$ ruff format --diff .
$ ruff check .
pylint
------
Ruff is capable of fixing most of the problems it encounters.
Be sure you commit first before running `ruff` so you can restore to a savepoint (and amend afterwards to prevent a double commit. : ::
To run pylint: ::
$ ruff format .
$ ruff check --fix .
# be careful with the --unsafe-fixes option, it can break your code
$ ruff check --fix --unsafe-fixes .
$ pylint <python files that you wish to lint>
The config for pylint is located in .pylintrc. It specifies:
* Use the pylint_django plugin. If using Celery, also use pylint_celery.
* Set max line length to 120 chars
* Disable linting messages for missing docstring and invalid name
* max-parents=13
pycodestyle
-----------
This is included in flake8's checks, but you can also run it separately to see a more detailed report: ::
$ pycodestyle <python files that you wish to lint>
The config for pycodestyle is located in setup.cfg. It specifies:
* Set max line length to 120 chars
* Exclude ``.tox,.git,*/migrations/*,*/static/CACHE/*,docs,node_modules``
The config for ruff is located in pyproject.toml.
On of the most important option is `tool.ruff.lint.select`.
`select` determines which linters are run. In example, `DJ <https://docs.astral.sh/ruff/rules/#flake8-django-dj>`_ refers to flake8-django.
For a full list of available linters, see `https://docs.astral.sh/ruff/rules/ <https://docs.astral.sh/ruff/rules/>`_
