> [!IMPORTANT]\
> **The official psf/black action has been released! 🚀** - Because of this, this repository's action is no longer trivial. Therefore, you are advised to use the [official black](https://black.readthedocs.io/en/stable/integrations/github_actions.html) action. Some features in this action are not in the official action. The differences between the two actions are documented in . If you think features are missing, please open a [pull request](https://github.com/rickstaa/action-black/pulls).
This action runs the [black formatter](https://github.com/psf/black) to check/format your python code on a push or pull request. It is similar to [reviewdog/action-black](https://github.com/reviewdog/action-black) that can annotate the black changes required with [Reviewdog](https://github.com/reviewdog/reviewdog). However, this version also allows you to format the code using GitHub actions (see #advanced-use-cases).
## Quickstart
In it's simplest form this action can be used to check/format your code using the black formatter.
```yaml
name: black-action
on: [push, pull_request]
jobs:
linter_name:
name: runner / black formatter
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: rickstaa/action-black@v1
with:
black_args: ". --check"
```
## Inputs
### `black_args`
**optional**: Black input arguments. Defaults to `. --check --diff`.
### `fail_on_error`
**optional**: Exit code when black formatting errors are found \[true, false]. Defaults to 'true'.
## Outputs
### `is_formatted`
Boolean specifying whether any files were formatted using the black formatter.
## Advanced use cases
### Annotate changes
This action can be combined with [reviewdog/action-suggester](https://github.com/reviewdog/action-suggester) also to annotate any possible changes (uses `git diff`).
```yaml
name: black-action
on: [push, pull_request]
jobs:
linter_name:
name: runner / black
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Check files using the black formatter
uses: rickstaa/action-black@v1
id: action_black
with:
black_args: "."
- name: Annotate diff changes using reviewdog
if: steps.action_black.outputs.is_formatted == 'true'
uses: reviewdog/action-suggester@v1
with:
tool_name: blackfmt
```
### Commit changes or create a pull request
This action can be combined with [peter-evans/create-pull-request](https://github.com/peter-evans/create-pull-request) to also apply the annotated changes to the repository.
```yaml
name: black-action
on: [push, pull_request]
jobs:
linter_name:
name: runner / black
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Check files using the black formatter
uses: rickstaa/action-black@v1
id: action_black
with:
black_args: "."
- name: Create Pull Request
if: steps.action_black.outputs.is_formatted == 'true'
uses: peter-evans/create-pull-request@v6
with:
token: ${{ secrets.GITHUB_TOKEN }}
title: "Format Python code with psf/black push"
commit-message: ":art: Format Python code with psf/black"
body: |
There appear to be some python formatting errors in ${{ github.sha }}. This pull request
uses the [psf/black](https://github.com/psf/black) formatter to fix these issues.
base: ${{ github.head_ref }} # Creates pull request onto pull request or commit branch
