It accepts a list of files or directories, and lints all discovered Python files, optionally fixing any fixable errors. When linting a directory, Ruff searches for Python files recursively in that directory and all its subdirectories: + +```console +$ ruff check # Lint files in the current directory. +$ ruff check --fix # Lint files in the current directory and fix any fixable errors. +$ ruff check --watch # Lint files in the current directory and re-lint on change. +$ ruff check path/to/code/ # Lint files in `path/to/code`. +``` + +## The Ruff Formatter +The Ruff formatter is an extremely fast Python code formatter designed as a drop-in replacement for [Black](https://pypi.org/project/black/), available as part of the `ruff` CLI via `ruff format`. + +### `ruff format` +`ruff format` is the primary entrypoint to the formatter. It accepts a list of files or directories, and formats all discovered Python files: + +```shell +ruff format # Format all files in the current directory. +ruff format path/to/code/ # Format all files in `path/to/code` (and any subdirectories). +ruff format path/to/file.py # Format a single file. +``` + +Similar to Black, running `ruff format /path/to/file.py` will format the given file or directory in-place, while `ruff format --check /path/to/file.py` will avoid writing any formatted files back, and instead exit with a non-zero status code upon detecting any unformatted files. + +For the full list of supported options, run `ruff format --help`. + +## Configuration +ruff can be configured via `ruff.toml` config file. See [here](https://docs.astral.sh/ruff/settings/) for a reference of all config parameters.
