## GitHub Actions
|
|
|
|
GitHub Actions has everything you need to run Ruff out-of-the-box:
|
|
|
|
```yaml
|
|
name: CI
|
|
on: push
|
|
jobs:
|
|
build:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- uses: actions/checkout@v4
|
|
- name: Install Python
|
|
uses: actions/setup-python@v5
|
|
with:
|
|
python-version: "3.11"
|
|
- name: Install dependencies
|
|
run: |
|
|
python -m pip install --upgrade pip
|
|
pip install ruff
|
|
# Update output format to enable automatic inline annotations.
|
|
- name: Run Ruff
|
|
run: ruff check --output-format=github .
|
|
```
|
|
|
|
Ruff can also be used as a GitHub Action via [`ruff-action`](https://github.com/chartboost/ruff-action).
|
|
|
|
By default, `ruff-action` runs as a pass-fail test to ensure that a given repository doesn't contain
|
|
any lint rule violations as per its [configuration](configuration.md).
|
|
However, under-the-hood, `ruff-action` installs and runs `ruff` directly, so it can be used to
|
|
execute any supported `ruff` command (e.g., `ruff check --fix`).
|
|
|
|
`ruff-action` supports all GitHub-hosted runners, and can be used with any published Ruff version
|
|
(i.e., any version available on [PyPI](https://pypi.org/project/ruff/)).
|
|
|
|
To use `ruff-action`, create a file (e.g., `.github/workflows/ruff.yml`) inside your repository
|
|
with:
|
|
|
|
```yaml
|
|
name: Ruff
|
|
on: [ push, pull_request ]
|
|
jobs:
|
|
ruff:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- uses: actions/checkout@v4
|
|
- uses: chartboost/ruff-action@v1
|
|
```
|
|
|
|
Alternatively, you can include `ruff-action` as a step in any other workflow file:
|
|
|
|
```yaml
|
|
- uses: chartboost/ruff-action@v1
|
|
```
|
|
|
|
`ruff-action` accepts optional configuration parameters via `with:`, including:
|
|
|
|
- `version`: The Ruff version to install (default: latest).
|
|
- `args`: The command-line arguments to pass to Ruff (default: `"check"`).
|
|
- `src`: The source paths to pass to Ruff (default: `[".", "src"]`).
|
|
|
|
For example, to run `ruff check --select B ./src` using Ruff version `0.0.259`:
|
|
|
|
```yaml
|
|
- uses: chartboost/ruff-action@v1
|
|
with:
|
|
version: 0.0.259
|
|
args: check --select B
|
|
src: "./src"
|
|
```
|
|
|
|
## pre-commit
|
|
|
|
Ruff can 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: v0.6.6
|
|
hooks:
|
|
# Run the linter.
|
|
- id: ruff
|
|
# Run the formatter.
|
|
- id: ruff-format
|
|
```
|
|
|
|
To enable lint fixes, add the `--fix` argument to the lint hook:
|
|
|
|
```yaml
|
|
- repo: https://github.com/astral-sh/ruff-pre-commit
|
|
# Ruff version.
|
|
rev: v0.6.6
|
|
hooks:
|
|
# Run the linter.
|
|
- id: ruff
|
|
args: [ --fix ]
|
|
# Run the formatter.
|
|
- id: ruff-format
|
|
```
|
|
|
|
To run the hooks over Jupyter Notebooks too, add `jupyter` to the list of allowed filetypes:
|
|
|
|
```yaml
|
|
- repo: https://github.com/astral-sh/ruff-pre-commit
|
|
# Ruff version.
|
|
rev: v0.6.6
|
|
hooks:
|
|
# Run the linter.
|
|
- id: ruff
|
|
types_or: [ python, pyi, jupyter ]
|
|
args: [ --fix ]
|
|
# Run the formatter.
|
|
- id: ruff-format
|
|
types_or: [ python, pyi, jupyter ]
|
|
```
|
|
|
|
When running with `--fix`, Ruff's lint hook should be placed _before_ Ruff's formatter hook, and
|
|
_before_ Black, isort, and other formatting tools, as Ruff's fix behavior can output code changes
|
|
that require reformatting.
|
|
|
|
When running without `--fix`, Ruff's formatter hook can be placed before or after Ruff's lint hook.
|
|
|
|
(As long as your Ruff configuration avoids any [linter-formatter incompatibilities](formatter.md#conflicting-lint-rules),
|
|
`ruff format` should never introduce new lint errors, so it's safe to run Ruff's format hook _after_
|
|
`ruff check --fix`.)
|
|
|
|
## `mdformat`
|
|
|
|
[mdformat](https://mdformat.readthedocs.io/en/stable/users/plugins.html#code-formatter-plugins) is
|
|
capable of formatting code blocks within Markdown. The [`mdformat-ruff`](https://github.com/Freed-Wu/mdformat-ruff)
|
|
plugin enables mdformat to format Python code blocks with Ruff.
