<i>Linting the CPython codebase from scratch.</i>
|
|
</p>
|
|
|
|
- ⚡️ 10-100x faster than existing linters (like Flake8) and formatters (like Black)
|
|
- 🐍 Installable via `pip`
|
|
- 🛠️ `pyproject.toml` support
|
|
- 🤝 Python 3.13 compatibility
|
|
- ⚖️ Drop-in parity with [Flake8](https://docs.astral.sh/ruff/faq/#how-does-ruffs-linter-compare-to-flake8), isort, and [Black](https://docs.astral.sh/ruff/faq/#how-does-ruffs-formatter-compare-to-black)
|
|
- 📦 Built-in caching, to avoid re-analyzing unchanged files
|
|
- 🔧 Fix support, for automatic error correction (e.g., automatically remove unused imports)
|
|
- 📏 Over [800 built-in rules](https://docs.astral.sh/ruff/rules/), with native re-implementations
|
|
of popular Flake8 plugins, like flake8-bugbear
|
|
- ⌨️ First-party [editor integrations](https://docs.astral.sh/ruff/editors) for [VS Code](https://github.com/astral-sh/ruff-vscode) and [more](https://docs.astral.sh/ruff/editors/setup)
|
|
- 🌎 Monorepo-friendly, with [hierarchical and cascading configuration](https://docs.astral.sh/ruff/configuration/#config-file-discovery)
|
|
|
|
Ruff aims to be orders of magnitude faster than alternative tools while integrating more
|
|
functionality behind a single, common interface.
|
|
|
|
Ruff can be used to replace [Flake8](https://pypi.org/project/flake8/) (plus dozens of plugins),
|
|
[Black](https://github.com/psf/black), [isort](https://pypi.org/project/isort/),
|
|
[pydocstyle](https://pypi.org/project/pydocstyle/), [pyupgrade](https://pypi.org/project/pyupgrade/),
|
|
[autoflake](https://pypi.org/project/autoflake/), and more, all while executing tens or hundreds of
|
|
times faster than any individual tool.
|
|
|
|
Ruff is extremely actively developed and used in major open-source projects like:
|
|
|
|
- [Apache Airflow](https://github.com/apache/airflow)
|
|
- [Apache Superset](https://github.com/apache/superset)
|
|
- [FastAPI](https://github.com/tiangolo/fastapi)
|
|
- [Hugging Face](https://github.com/huggingface/transformers)
|
|
- [Pandas](https://github.com/pandas-dev/pandas)
|
|
- [SciPy](https://github.com/scipy/scipy)
|
|
|
|
...and [many more](#whos-using-ruff).
|
|

|
> Why is Ruff a gamechanger? Primarily because it is nearly 1000x faster. Literally. Not a typo. On
|
|

|
|
You can also install Ruff via [Homebrew](https://formulae.brew.sh/formula/ruff), [Conda](https://anaconda.org/conda-forge/ruff),
|
|
and with [a variety of other package managers](https://docs.astral.sh/ruff/installation/).
|
|
|
|
### Usage
|
|
|
|
To run Ruff as a linter, try any of the following:
|
|
|
|
```shell
|
|
ruff check # Lint all files in the current directory (and any subdirectories).
|
|
ruff check path/to/code/ # Lint all files in `/path/to/code` (and any subdirectories).
|
|
ruff check path/to/code/*.py # Lint all `.py` files in `/path/to/code`.
|
|
ruff check path/to/code/to/file.py # Lint `file.py`.
|
|
ruff check @arguments.txt # Lint using an input file, treating its contents as newline-delimited command-line arguments.
|
|
```
|
|
|
|
Or, to run Ruff as a formatter:
|
|
|
|
```shell
|
|
ruff format # Format all files in the current directory (and any subdirectories).
|
|
ruff format path/to/code/ # Format all files in `/path/to/code` (and any subdirectories).
|
|
ruff format path/to/code/*.py # Format all `.py` files in `/path/to/code`.
|
|
ruff format path/to/code/to/file.py # Format `file.py`.
|
|
ruff format @arguments.txt # Format using an input file, treating its contents as newline-delimited command-line arguments.
|
|
```
|
|
|
|
Ruff can also be used as a [pre-commit](https://pre-commit.com/) hook via [`ruff-pre-commit`](https://github.com/astral-sh/ruff-pre-commit):
|
|
|
|
```yaml
|
|
- repo: https://github.com/astral-sh/ruff-pre-commit
|
|
# Ruff version.
|
|
rev: v0.12.2
|
|
hooks:
|
|
# Run the linter.
|
|
- id: ruff-check
|
|
args: [ --fix ]
|
|
# Run the formatter.
|
|
- id: ruff-format
|
|
```
|
|
|
|
Ruff can also be used as a [VS Code extension](https://github.com/astral-sh/ruff-vscode) or with [various other editors](https://docs.astral.sh/ruff/editors/setup).
|
|
|
|
Ruff can also be used as a [GitHub Action](https://github.com/features/actions) via
|
|
[`ruff-action`](https://github.com/astral-sh/ruff-action):
|
|
|
|
```yaml
|
|
name: Ruff
|
|
on: [ push, pull_request ]
|
|
jobs:
|
|
ruff:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- uses: actions/checkout@v4
|
|
- uses: astral-sh/ruff-action@v3
|
|
```
|
|
|
|
### Configuration<a id="configuration"></a>
|
|
|
|
Ruff can be configured through a `pyproject.toml`, `ruff.toml`, or `.ruff.toml` file (see:
|
|
[_Configuration_](https://docs.astral.sh/ruff/configuration/), or [_Settings_](https://docs.astral.sh/ruff/settings/)
|
|
for a complete list of all configuration options).
|
|
|
|
If left unspecified, Ruff's default configuration is equivalent to the following `ruff.toml` file:
|
|
|
|
```toml
|
|
# Exclude a variety of commonly ignored directories.
|
|
exclude = [
|
|
".bzr",
|
|
".direnv",
|
|
".eggs",
|
|
".git",
|
|
".git-rewrite",
|
|
".hg",
|
|
".ipynb_checkpoints",
|
|
".mypy_cache",
|
|
".nox",
|
|
".pants.d",
|
|
".pyenv",
|
|
".pytest_cache",
|
|
".pytype",
|
|
".ruff_cache",
|
|
".svn",
|
|
".tox",
|
|
".venv",
|
|
".vscode",
|
|
"__pypackages__",
|
|
"_build",
|
|
"buck-out",
|
|
"build",
|
|
"dist",
|
|
"node_modules",
|
|
"site-packages",
|
|
"venv",
|
|
]
|
|
|
|
# Same as Black.
|
|
line-length = 88
|
|
indent-width = 4
|
|
|
|
# Assume Python 3.9
|
|
target-version = "py39"
|
|
|
|
[lint]
|
|
# Enable Pyflakes (`F`) and a subset of the pycodestyle (`E`) codes by default.
|
|
select = ["E4", "E7", "E9", "F"]
|
|
ignore = []
|
|
|
|
# Allow fix for all enabled rules (when `--fix`) is provided.
|
|
fixable = ["ALL"]
|
|
unfixable = []
|
|
|
|
# Allow unused variables when underscore-prefixed.
|
|
dummy-variable-rgx = "^(_+|(_+[a-zA-Z0-9_]*[a-zA-Z0-9]+?))$"
|
|
|
|
[format]
|
|
# Like Black, use double quotes for strings.
|
|
quote-style = "double"
|
|
|
|
# Like Black, indent with spaces, rather than tabs.
|
|
indent-style = "space"
|
|
|
|
# Like Black, respect magic trailing commas.
|
|
skip-magic-trailing-comma = false
|
|
|
|
# Like Black, automatically detect the appropriate line ending.
|
|
line-ending = "auto"
|
|
```
|
|
|
|
Note that, in a `pyproject.toml`, each section header should be prefixed with `tool.ruff`. For
|
|
example, `[lint]` should be replaced with `[tool.ruff.lint]`.
|
|
|
|
Some configuration options can be provided via dedicated command-line arguments, such as those
|
|
related to rule enablement and disablement, file discovery, and logging level:
|
|
|
|
```shell
|
|
ruff check --select F401 --select F403 --quiet
|
|
```
|
|
|
|
The remaining configuration options can be provided through a catch-all `--config` argument:
|
|
|
|
```shell
|
|
ruff check --config "lint.per-file-ignores = {'some_file.py' = ['F841']}"
|
|
```
|
|
|
|
To opt in to the latest lint rules, formatter style changes, interface updates, and more, enable
|
|
[preview mode](https://docs.astral.sh/ruff/rules/) by setting `preview = true` in your configuration
|
|
file or passing `--preview` on the command line. Preview mode enables a collection of unstable
|
|
features that may change prior to stabilization.
|
|
|
|
See `ruff help` for more on Ruff's top-level commands, or `ruff help check` and `ruff help format`
|
|
for more on the linting and formatting commands, respectively.
|
|
|
|
## Rules<a id="rules"></a>
|
|
|
|
<!-- Begin section: Rules -->
|
|
|
|
**Ruff supports over 800 lint rules**, many of which are inspired by popular tools like Flake8,
|
|
isort, pyupgrade, and others. Regardless of the rule's origin, Ruff re-implements every rule in
|
|
Rust as a first-party feature.
|
|
|
|
By default, Ruff enables Flake8's `F` rules, along with a subset of the `E` rules, omitting any
|
|
stylistic rules that overlap with the use of a formatter, like `ruff format` or
|
|
[Black](https://github.com/psf/black).
|
|
|
|
If you're just getting started with Ruff, **the default rule set is a great place to start**: it
|
|
catches a wide variety of common errors (like unused imports) with zero configuration.
|
|
|
|
<!-- End section: Rules -->
|
|
|
|
Beyond the defaults, Ruff re-implements some of the most popular Flake8 plugins and related code

[pyupgrade](https://github.com/asottile/pyupgrade), and [isort](https://github.com/PyCQA/isort).
|
|
|
|
In some cases, Ruff includes a "direct" Rust port of the corresponding tool.
|
|
We're grateful to the maintainers of these tools for their work, and for all
|
|
the value they've provided to the Python community.
|
|
|
|
Ruff's formatter is built on a fork of Rome's [`rome_formatter`](https://github.com/rome/tools/tree/main/crates/rome_formatter),
|
|
and again draws on both API and implementation details from [Rome](https://github.com/rome/tools),
|
|
[Prettier](https://github.com/prettier/prettier), and [Black](https://github.com/psf/black).
|
|
|
|
Ruff's import resolver is based on the import resolution algorithm from [Pyright](https://github.com/microsoft/pyright).
|
|
|
|
Ruff is also influenced by a number of tools outside the Python ecosystem, like
|
|
[Clippy](https://github.com/rust-lang/rust-clippy) and [ESLint](https://github.com/eslint/eslint).
|
|
|
|
Ruff is the beneficiary of a large number of [contributors](https://github.com/astral-sh/ruff/graphs/contributors).
