# Code Style

## Pre-Commit

Alliance Auth is a team effort with developers of various skill levels and background. To avoid significant drift or formatting changes between developers, we use [pre-commit](https://pre-commit.com/) to apply a very minimal set of formatting checks to code contributed to the project.

Pre-commit is also very popular with our Community Apps and may be significantly more opinionated or looser depending on the project.

To get started, `pip install pre-commit`, then `pre-commit install` to add the git hooks.

Before any code is "git push"-ed, pre-commit will check it for uniformity and correct it if possible

```shell
check python ast.....................................(no files to check)Skipped

```

## Editorconfig

[Editorconfig](https://editorconfig.org/) is supported my most IDE's to streamline the most common editor disparities. While checked by our pre-commit file, using this in your IDE (Either automatically or via a plugin) will minimize the corrections that may need to be made.

## Doc Strings

We prefer either [PEP-287](https://peps.python.org/pep-0287/)/[reStructuredText](https://docutils.sourceforge.io/rst.html) or [Google](https://google.github.io/styleguide/pyguide.html#381-docstrings) Docstrings.

These can be used to automatically generate our Sphinx documentation in either format.

## Best Practice

It is advisable to avoid wide formatting changes on code that is not being modified by an MR. Further to this, automated code formatting should be kept to a minimal when modifying sections of existing files.

If you are contributing whole modules or rewriting large sections of code, you may use any legible code formatting valid under Python.
