To run the formatter on Jupyter Notebooks, Black must be installed with an extra dependency (`black[jupyter]`). This commit adds an optional argument to install Black with this dependency when using the official GitHub Action [1]. To enable the formatter on Jupyter Notebooks, just add `jupyter: true` as an argument. Feature requested at [2].

# 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 the `colorama` extra so the `--color` flag
|
|
should work fine.
|
|
|
|
## 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`. This can be
|
|
any
|
|
[valid version specifier](https://packaging.python.org/en/latest/glossary/#term-Version-Specifier)
|
|
or just the version number if you want an exact 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.
|
|
|
|
If you want to include Jupyter Notebooks, _Black_ must be installed with the `jupyter`
|
|
extra. Installing the extra and including Jupyter Notebook files can be configured via
|
|
`jupyter` (default is `false`).
|
|
|
|
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"
|
|
jupyter: true
|
|
version: "21.5b1"
|
|
```
|
|
|
|
If you want to match versions covered by Black's
|
|
[stability policy](labels/stability-policy), you can use the compatible release operator
|
|
(`~=`):
|
|
|
|
```yaml
|
|
- uses: psf/black@stable
|
|
with:
|
|
options: "--check --verbose"
|
|
src: "./src"
|
|
version: "~= 22.0"
|
|
```
