# GitHub Actions integration
|
|
|
|
You can use _Black_ within a GitHub Actions workflow without setting your own Python
|
|
environment. Great for enforcing that your code matches the _Black_ code style.
|
|
|
|
## Compatibility
|
|
|
|
This action is known to support all GitHub-hosted runner OSes. In addition, only
|
|
published versions of _Black_ are supported (i.e. whatever is available on PyPI).
|
|
|
|
Finally, this action installs _Black_ with both the `colorama` and `python2` extras so
|
|
the `--color` flag and formatting Python 2 code are supported.
|
|
|
|
## Usage
|
|
|
|
Create a file named `.github/workflows/black.yml` inside your repository with:
|
|
|
|
```yaml
|
|
name: Lint
|
|
|
|
on: [push, pull_request]
|
|
|
|
jobs:
|
|
lint:
|
|
runs-on: ubuntu-latest
|
|
steps:
|
|
- uses: actions/checkout@v2
|
|
- uses: psf/black@stable
|
|
```
|
|
|
|
We recommend the use of the `@stable` tag, but per version tags also exist if you prefer
|
|
that. Note that the action's version you select is independent of the version of _Black_
|
|
the action will use.
|
|
|
|
The version of _Black_ the action will use can be configured via `version`. The action
|
|
defaults to the latest release available on PyPI. Only versions available from PyPI are
|
|
supported, so no commit SHAs or branch names.
|
|
|
|
You can also configure the arguments passed to _Black_ via `options` (defaults to
|
|
`'--check --diff'`) and `src` (default is `'.'`)
|
|
|
|
Here's an example configuration:
|
|
|
|
```yaml
|
|
- uses: psf/black@stable
|
|
with:
|
|
options: "--check --verbose"
|
|
src: "./src"
|
|
version: "21.5b1"
|
|
```
