Ruff
An extremely fast Python linter, written in Rust.
Linting the CPython codebase from scratch.
-
β‘οΈ 10-100x faster than existing linters -
π Installable viapip -
π€ Python 3.10 compatibility -
π οΈ pyproject.tomlsupport -
π¦ ESLint-inspired cache support -
π§ ESLint-inspired autofix support (e.g., automatically remove unused imports) -
π TypeScript-inspired--watchsupport, for continuous file monitoring -
βοΈ Near-parity with the built-in Flake8 rule set -
π Native re-implementations of popular Flake8 plugins, likeflake8-docstrings(pydocstyle)
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 (plus a variety of plugins), pydocstyle, yesqa, and even a subset of pyupgrade and autoflake all while executing tens or hundreds of times faster than any individual tool.

Installation and Usage
Installation
Available as ruff on PyPI:
pip install ruff
Usage
To run Ruff, try any of the following:
ruff path/to/code/to/check.py
ruff path/to/code/
ruff path/to/code/*.py
You can run Ruff in --watch mode to automatically re-run on-change:
ruff path/to/code/ --watch
Ruff also works with pre-commit:
repos:
- repo: https://github.com/charliermarsh/ruff-pre-commit
rev: v0.0.77
hooks:
- id: lint
Configuration
Ruff is configurable both via pyproject.toml and the command line.
For example, you could configure Ruff to only enforce a subset of rules with:
[tool.ruff]
line-length = 88
select = [
"F401",
"F403",
]
Alternatively, on the command-line:
ruff path/to/code/ --select F401 --select F403
See ruff --help for more:
ruff: An extremely fast Python linter.
Usage: ruff [OPTIONS] <FILES>...
Arguments:
<FILES>...
Options:
--config <CONFIG>
Path to the `pyproject.toml` file to use for configuration
-v, --verbose
Enable verbose logging
-q, --quiet
Disable all logging (but still exit with status code "1" upon detecting errors)
-e, --exit-zero
Exit with status code "0", even upon detecting errors
-w, --watch
Run in watch mode by re-running whenever files change
-f, --fix
Attempt to automatically fix lint errors
-n, --no-cache

Excluding files
Exclusions are based on globs, and can be either:
- Single-path patterns, like
.mypy_cache(to exclude any directory named.mypy_cachein the tree),foo.py(to exclude any file namedfoo.py), orfoo_*.py(to exclude any file matchingfoo_*.py). - Relative patterns, like
directory/foo.py(to exclude that specific file) ordirectory/*.py(to exclude any Python files indirectory). Note that these paths are relative to the project root (e.g., the directory containing yourpyproject.toml).
Ignoring errors
To omit a lint check entirely, add it to the "ignore" list via --ignore or --extend-ignore, either on the command-line or in your project.toml file.
To ignore an error in-line, Ruff uses a noqa system similar to Flake8. To ignore an individual error, add # noqa: {code} to the end of the line, like so:
# Ignore F841.
x = 1 # noqa: F841
# Ignore E741 and F841.
i = 1 # noqa: E741, F841
# Ignore _all_ errors.
x = 1 # noqa
Note that, for multi-line strings, the noqa directive should come at the end of the string, and will apply to the entire body, like so:
"""Lorem ipsum dolor sit amet.
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
""" # noqa: E501
Ruff supports several workflows to aid in noqa management.
First, Ruff provides a special error code, M001, to enforce that your noqa directives are "valid", in that the errors they say they ignore are actually being triggered on that line (and thus suppressed). You can run ruff /path/to/file.py --extend-select M001 to flag unused noqa directives.
Second, Ruff can automatically remove unused noqa directives via its autofix functionality. You can run ruff /path/to/file.py --extend-select M001 --fix to automatically remove unused noqa directives.
Third, Ruff can automatically add noqa directives to all failing lines. This is useful when migrating a new codebase to Ruff. You can run ruff /path/to/file.py --add-noqa to automatically add noqa directives to all failing lines, with the appropriate error codes.
Supported Rules
By default, Ruff enables all E, W, and F error codes, which correspond to those built-in to Flake8.

FAQ
Is Ruff compatible with Black?
Yes. Ruff is compatible with Black out-of-the-box, as long as the line-length setting is consistent between the two.
As a project, Ruff is designed to be used alongside Black and, as such, will defer implementing stylistic lint rules that are obviated by autoformatting.
How does Ruff compare to Flake8?
Ruff can be used as a (near) drop-in replacement for Flake8 when used (1) without or with a small number of plugins, (2) alongside Black, and (3) on Python 3 code.
Under those conditions Ruff is missing 14 rules related to string .format calls, 1 rule related to docstring parsing, and 1 rule related to redefined variables.
Ruff re-implements some of the most popular Flake8 plugins and related code quality tools natively, including:
pydocstyleyesqaflake8-docstringsflake8-builtinsflake8-superflake8-printflake8-comprehensionsflake8-bugbear(3/32)pyupgrade(8/34)autoflake(1/7)
Beyond rule-set parity, Ruff suffers from the following limitations vis-Γ -vis Flake8:
- Ruff does not yet support a few Python 3.9 and 3.10 language features, including structural pattern matching and parenthesized context managers.
- Flake8 has a plugin architecture and supports writing custom lint rules. (To date, popular Flake8 plugins have been re-implemented within Ruff directly.)
Which tools does Ruff replace?
Today, Ruff can be used to replace Flake8 when used with any of the following plugins:
flake8-docstringsflake8-builtinsflake8-superflake8-printflake8-comprehensionsflake8-bugbear(3/32)
Ruff also implements the functionality that you get from yesqa, and a subset of the rules implemented in pyupgrade (8/34).
If you're looking to use Ruff, but rely on an unsupported Flake8 plugin, free to file an Issue.
Do I need to install Rust to use Ruff?
Nope! Ruff is available as ruff on PyPI:
pip install ruff
Ruff ships with wheels for all major platforms, which enables pip to install Ruff without relying on Rust at all.
Can I write my own plugins for Ruff?
Ruff does not yet support third-party plugins, though a plugin system is within-scope for the project. See #283 for more.
Does Ruff support NumPy- or Google-style docstrings?
Yes! To enable a specific docstring convention, start by enabling all pydocstyle error codes, and then selectively disabling based on your preferred convention.
For example, if you're coming from flake8-docstrings, the following configuration is equivalent to --docstring-convention numpy:
[tool.ruff]
extend-select = [
"D100",
"D101",
"D102",
"D103",
"D104",
"D105",
"D106",

"D409",
"D410",
"D411",
"D412",
"D413",

]
Similarly, the following is equivalent to --docstring-convention google:
[tool.ruff]
extend-select = [

"D104",

Development
Ruff is written in Rust (1.63.0). You'll need to install the Rust toolchain for development.
Assuming you have cargo installed, you can run:
cargo run resources/test/fixtures
cargo fmt
cargo clippy
cargo test
Releases
Ruff is distributed on PyPI, and published via maturin.
See: .github/workflows/release.yaml.
Benchmarks
First, clone CPython. It's a large and diverse Python codebase, which makes it a good target for benchmarking.
git clone --branch 3.10 https://github.com/python/cpython.git resources/test/cpython
Add this pyproject.toml to the CPython directory:
[tool.ruff]
line-length = 88
extend-exclude = [

"Lib/lib2to3/tests/data/crlf.py",
"Lib/lib2to3/tests/data/different_encoding.py",
