# 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 default committer is "GitHub Actions <actions@github.com>" and the default author of the commit is "Your GitHub Username <github_username@users.noreply.github.com>".
If no changes are detected, the Action 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 this [commit](https://github.com/elstudio/actions-js-build/blob/41d604d6e73d632e22eac40df8cc69b5added04b/commit/entrypoint.sh)-Action by Eric Johnson.
*This Action currently can't be used in conjunction with pull requests of forks. See [issue #25](https://github.com/stefanzweifel/git-auto-commit-action/issues/25) for more information.*
## Usage
**Note:** This Action requires that you use `action/checkout@v2` or above to checkout your repository.
Add the following step at the end of your job.
```yaml
- uses: stefanzweifel/git-auto-commit-action@v4.1.3
with:
commit_message: Apply automatic changes
# Optional name of the branch the commit should be pushed to
# Required if Action is used in Workflow listening to the `pull_request` event
branch: ${{ github.head_ref }}
# Optional git params
commit_options: '--no-verify --signoff'
# Optional glob pattern of files which should be added to the commit
file_pattern: src/\*.js
# Optional local file path to the repository
repository: .
# Optional commit user and author settings
commit_user_name: My GitHub Actions Bot
commit_user_email: my-github-actions-bot@example.org
commit_author: Author <actions@github.com>
# Optional tag message. Will create and push a new tag to the remote repository
tagging_message: 'v1.0.0'
```
The Action will only commit files back, if changes are available. The resulting commit **will not trigger** another GitHub Actions Workflow run!
We recommend to use this Action in Workflows, which listen to the `pull_request` event. You can then use the option `branch: ${{ github.head_ref }}` to set up the branch name correctly.
If you don't pass a branch name, the Action will try to push the commit to a branch with the same name, as with which the repo has been checked out.
## Example Usage
This Action will only work, if the job in your Workflow changes 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.
### Example on `pull_request` event
```yaml
name: php-cs-fixer
on: pull_request
jobs:
php-cs-fixer:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
with:
ref: ${{ github.head_ref }}
- name: Run php-cs-fixer
uses: docker://oskarstark/php-cs-fixer-ga
- uses: stefanzweifel/git-auto-commit-action@v4.1.3
with:
commit_message: Apply php-cs-fixer changes
branch: ${{ github.head_ref }}
```
### Example on `push` event
```yaml
name: php-cs-fixer
on: push
jobs:
php-cs-fixer:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
- name: Run php-cs-fixer
uses: docker://oskarstark/php-cs-fixer-ga
- uses: stefanzweifel/git-auto-commit-action@v4.1.3
with:
commit_message: Apply php-cs-fixer changes
```
### Inputs
Checkout [`action.yml`](https://github.com/stefanzweifel/git-auto-commit-action/blob/master/action.yml) for a full list of supported inputs.
## Outputs
You can use these outputs to trigger other Actions in your Workflow run based on the result of `git-auto-commit-action`.
- `changes_detected`: Returns either "true" or "false" if the repository was dirty and files have changed.
## Troubleshooting
### Can't push commit to repository
If your Workflow can't push the commit to the repository because of authentication issues, please update your Workflow configuration and usage of [`actions/checkout`](https://github.com/actions/checkout#usage). (Updating the `token` value with a Personal Access Token should fix your issues)
### Commit of this Action does not trigger a new Workflow run
As mentioned in the [Usage](#Usage) section, the commit created by this Action **will not trigger** a new Workflow run automatically.
This is due to limitations set up by GitHub:
> An action in a workflow run can't trigger a new workflow run. For example, if an action pushes code using the repository's GITHUB_TOKEN, a new workflow will not run even when the repository contains a workflow configured to run when push events occur.
[Source](https://help.github.com/en/actions/reference/events-that-trigger-workflows)
You can change this by creating a new [Personal Access Token (PAT)](https://github.com/settings/tokens/new), storing the token as a secret in your repository and then passing the new token to the [`actions/checkout`](https://github.com/actions/checkout#usage) Action.
#### Example Workflow
```yaml
name: php-cs-fixer
on: push
jobs:
php-cs-fixer:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v2
with:
token: ${{ secrets.PAT_TOKEN }}
- name: Run php-cs-fixer
uses: docker://oskarstark/php-cs-fixer-ga
- uses: stefanzweifel/git-auto-commit-action@v4.1.3
with:
commit_message: Apply php-cs-fixer changes
```
## Known Issues
- GitHub currently prohibits Actions like this to push changes from a fork to the upstream repository. See [issue #25](https://github.com/stefanzweifel/git-auto-commit-action/issues/25) for more information.
