Ruff helps fashionable Python with 3.12 compatibility and `pyproject.toml`. It additionally gives computerized repair assist, caching, and editor integrations. Ruff is monorepo-friendly and utilized in main open-source tasks like Pandas, FastAPI, and extra. By combining pace, performance, and usefulness, Ruff integrates linting, formatting, and computerized 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 are able to use the DagHub repository kingabzpro/Yoga-Pose-Classification. You possibly can clone it or use your personal undertaking to format.

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 undertaking, 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 straightforward – they’re useful in imposing coding requirements and conventions. Because of this, each you and your crew can consider 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 undertaking, you must 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 information. 

2 information have been reformatted and we’ve 2 Pocket book information. 

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

 

We’ve additionally fastened the problems in these information by operating the `verify` command once more. 

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

 

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

It is easy to configure Ruff for Jupyter Notebooks by enhancing 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 by means of 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 can be used as a GitHub Motion through `ruff-action`:
