# Ruff

[**Ruff**](https://github.com/astral-sh/ruff) is a linter for Python.

ruff is composed of several linter commands.

`ruff` is for formatting general python code.

You can enable the `ruff` linter with:

```shell
trunk check enable ruff
```

`ruff-nbqa` is for extra support for Jupyter notebooks.

You can enable the `ruff-nbqa` linter with:

```shell
trunk check enable ruff-nbqa
```

## Auto Enabling

Ruff will be auto-enabled if any *Python, Python-interface, Jupyter, Python, Python-interface, Python, Python-interface, Python, Python-interface, Python or Python-interface* files are present.

## Settings

Ruff supports the following config files:

* `ruff.toml`

You can move these files to `.trunk/configs` and `trunk check` will still find them. See [Moving Linters](https://docs.trunk.io/code-quality/overview/configure-linters#moving-linters) for more info. Trunk Code Quality provides a default `ruff.toml` if your project does not already have one.
