Ruff is an especially quick Python linter and formatter written in Rust that goals to exchange and enhance upon present instruments like Flake8, Black, and isort. It supplies 10-100x sooner efficiency whereas sustaining parity via over 700 built-in guidelines and reimplementation of fashionable plugins.

Ruff helps fashionable Python with 3.12 compatibility and `pyproject.toml`. It additionally provides computerized repair assist, caching, and editor integrations. Ruff is monorepo-friendly and utilized in main open-source initiatives like Pandas, FastAPI, and extra. By combining pace, performance, and value, Ruff integrates linting, formatting, and computerized fixing in a unified software that’s orders of magnitude sooner than present choices.



We are able to simply set up `ruff` through the use of PIP.  


To check how simple and quick it’s to run Ruff, we will use the DagHub repository kingabzpro/Yoga-Pose-Classification. You may clone it or use your individual undertaking to format.

First, we are going to run a linter over our undertaking. You can too 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’ll be able to see, it has mounted the 1 fixable error.

To format the undertaking, we are going to use the `ruff format` command.

$ ruff format .
>>> 3 recordsdata reformatted


The Ruff linter and formatter have made quite a few modifications to the code. However, why will we require these instruments? The reply is easy – they’re helpful in implementing coding requirements and conventions. In consequence, each you and your staff can think about the numerous points 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 undertaking, it’s a must to create `ruff.toml` file and add the next code:

extend-include = ["*.ipynb"]


You can too do the identical with the `pyproject.toml` file. 

After that re-run the instructions to see it making modifications to Jupyter pocket book recordsdata. 

2 recordsdata have been reformatted and now we have 2 Pocket book recordsdata. 

$ ruff format .
>>> 2 recordsdata reformatted, 3 recordsdata left unchanged


We’ve got additionally mounted the problems in these recordsdata by operating the `verify` command once more. 

$ ruff verify --fix .
>>> Discovered 51 errors (6 mounted, 45 remaining).


The ultimate result’s superb. It has made the entire mandatory modifications with out breaking the code.

It is simple to configure Ruff for Jupyter Notebooks by enhancing the `ruff.toml` file to regulate the linter and formatter settings. Take a look at the configuring Ruff documentation for extra particulars. 

target-version = "py311"
extend-include = ["*.ipynb"]
line-length = 80

extend-select = [
  "UP",  # pyupgrade
  "D",   # 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
    # Run the linter.
    - id: ruff
      args: [ --fix ]
    # Run the formatter.
    - id: ruff-format


It can be used as a GitHub Motion by way of `ruff-action`:

title: Ruff
on: [ push, pull_request ]
    runs-on: ubuntu-latest
      - makes use of: actions/checkout@v3
      - makes use of: chartboost/ruff-action@v1



Essentially the most fulfilling side of Ruff is its VSCode extension. It simplifies formatting and linting, eliminating the necessity for third-party extensions. Merely seek for Ruff on the extension market to put in it.

I’ve configured `setting.json` in order that it codecs on save.



Ruff delivers lightning-fast linting and formatting for cleaner, extra constant Python code. With over 700 built-in guidelines reimplemented in Rust for efficiency, Ruff attracts inspiration from fashionable instruments like Flake8, isort, and pyupgrade to implement a complete set of coding finest practices. The curated ruleset focuses on catching bugs and demanding model points with out extreme nitpicking.

Seamless integrations with pre-commit hooks, GitHub Actions, and editors like VSCode make incorporating Ruff into fashionable Python workflows simple. The unrivaled pace and thoughtfully designed ruleset make Ruff a vital software for Python builders who worth speedy suggestions, clear code, and clean staff collaboration.
