# git-auto-commit-action
This GitHub Action automatically commits files which have been changed during a Workflow run and pushes the Commit back to GitHub.
The Committer is "GitHub Actions <actions@github.com>" and the Author of the Commit can be configured with input variables.
If no changes are available, the Actions does nothing.
This Action has been inspired and adapted from the [auto-commit](https://github.com/cds-snc/github-actions/tree/master/auto-commit
)-Action of the Canadian Digital Service and the [commit](https://github.com/elstudio/actions-js-build/blob/41d604d6e73d632e22eac40df8cc69b5added04b/commit/entrypoint.sh)-Action by Eric Johnson.
## Usage
Add the following step at the end of your job.
```yaml
- uses: stefanzweifel/git-auto-commit-action@v2.1.0
with:
commit_message: Apply automatic changes
branch: ${{ github.head_ref }}
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```
The Action will only commit files back, if changes are available. The resulting commit **will not trigger** another GitHub Actions Workflow run!
### Inputs
The following inputs are required
- `commit_message`: The commit message used when changes are available
- `branch`: Branch name where changes should be pushed to
### Environment Variables
The `GITHUB_TOKEN` secret is required. It is automatically available in your repository. You have to add it to the configuration though.
## Example Usage
This Action will only work, if the job in your workflow changes project files.
The most common use case for this, is when you're running a Linter or Code-Style fixer on GitHub Actions.
In this example I'm running `php-cs-fixer` in a PHP project.
```yaml
on: push
name: php-cs-fixer
jobs:
php-cs-fixer:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v1
with:
fetch-depth: 1
- name: Run php-cs-fixer
uses: docker://oskarstark/php-cs-fixer-ga
- name: Commit changed files
uses: stefanzweifel/git-auto-commit-action@v2.1.0
with:
commit_message: Apply php-cs-fixer changes
branch: ${{ github.head_ref }}
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
```
