Ruff is an especially quick Python linter and formatter written in Rust that goals to interchange and enhance upon present instruments like Flake8, Black, and isort. It gives 10-100x sooner efficiency whereas sustaining parity via over 700 built-in guidelines and reimplementation of common plugins.
Stats from Ruff | Linting the CPython codebase from scratch
Ruff helps trendy Python with 3.12 compatibility and `pyproject.toml`. It additionally provides automated repair assist, caching, and editor integrations. Ruff is monorepo-friendly and utilized in main open-source tasks like Pandas, FastAPI, and extra. By combining velocity, performance, and value, Ruff integrates linting, formatting, and automated fixing in a unified instrument that’s orders of magnitude sooner than present choices.
We are able to simply set up `ruff` by utilizing PIP.
To check how straightforward and quick it’s to run Ruff, we will use the DagHub repository kingabzpro/Yoga-Pose-Classification. You may clone it or use your personal venture to format.
First, we are going to run a linter over our venture. You may also run linter on a single file by changing “.” with file location.
Ruff has recognized 9 errors and 1 fixable error. To repair the error, we are going to use the –fix flag.
As you may see, it has fastened the 1 fixable error.
To format the venture, we are going to use the `ruff format` command.
$ ruff format . >>> 3 information reformatted
The Ruff linter and formatter have made quite a few modifications to the code. However, why can we require these instruments? The reply is easy – they’re useful in implementing coding requirements and conventions. In consequence, each you and your group can focus on the numerous facets of your code. Furthermore, they assist improve the standard, maintainability, and safety of our code.

To make use of Ruff for Jupyter Notebooks within the venture, it’s important to create `ruff.toml` file and add the next code:
extend-include = ["*.ipynb"]
You may also do the identical with the `pyproject.toml` file.
After that re-run the instructions to see it making modifications to Jupyter pocket book information.
2 information have been reformatted and we’ve got 2 Pocket book information.
$ ruff format . >>> 2 information reformatted, 3 information left unchanged
Now we have additionally fastened the problems in these information by working the `examine` command once more.
$ ruff examine --fix . >>> Discovered 51 errors (6 fastened, 45 remaining).
The ultimate result’s superb. It has made the entire crucial modifications with out breaking the code.

It is easy to configure Ruff for Jupyter Notebooks by modifying the `ruff.toml` file to regulate the linter and formatter settings. Try the configuring Ruff documentation for extra particulars.
target-version = "py311" extend-include = ["*.ipynb"] line-length = 80 [lint] extend-select = [ "UP", # pyupgrade "D", # pydocstyle ] [lint.pydocstyle] conference = "google"
Builders and groups can use Ruff as a pre-commit hook via the `ruff-pre-commit`:
- repo: https://github.com/astral-sh/ruff-pre-commit # Ruff model. rev: v0.1.5 hooks: # Run the linter. - id: ruff args: [ --fix ] # Run the formatter. - id: ruff-format
It will also be used as a GitHub Motion by way of `ruff-action`:
title: Ruff on: [ push, pull_request ] jobs: ruff: runs-on: ubuntu-latest steps: - makes use of: actions/checkout@v3 - makes use of: chartboost/ruff-action@v1
