# git-auto-commit Action
|
||
|
||
> The GitHub Action for committing files for the 80% use case.

|
||
</a>
|
||
|
||
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>".
|
||
|
||
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.
|
||
|
||

```
|
||
|
||
## Example
|
||
|
||
In this example, we're running `php-cs-fixer` in a PHP project to fix the codestyle automatically, then commit possible changed files back to the repository.
|
||
|
||
Note that we explicitly specify `${{ github.head_ref }}` in the checkout Action.
|
||
This is required in order to work with the `pull_request` event (or any other non-`push` event).
|
||
|
||
```yaml
|
||
name: php-cs-fixer
|
||
|
||
on:
|
||
pull_request:
|
||
push:
|
||
branches:
|
||
- "main"
|
||
|
||
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
|
||
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.
|
||
|
||
### Example
|
||
|
||
```yaml
|
||
- name: "Run if changes have been detected"
|
||
if: steps.auto-commit-action.outputs.changes_detected == 'true'
|
||
run: echo "Changes!"
|
||
|
||
- name: "Run if no changes have been detected"
|
||
if: steps.auto-commit-action.outputs.changes_detected == 'false'
|
||
run: echo "No Changes!"
|
||
```
|
||
|
||
## Limitations & Gotchas
|
||
|
||
### Checkout the correct branch
|
||
|
||
You must use `action/checkout@v2` or later versions to checkout the repository.
|
||
In non-`push` events, such as `pull_request`, make sure to specify the `ref` to checkout:
|
||
|
||
```yaml
|
||
- uses: actions/checkout@v2
|
||
with:
|
||
ref: ${{ github.head_ref }}
|
||
```
|
||
|
||
You have to do this to avoid that the `checkout`-Action clones your repository in a detached state.
|
||
|
||
### Commits of this Action do not trigger new Workflow runs
|
||
|
||
The resulting commit **will not trigger** another GitHub Actions Workflow run.
|
||
This is due to [limititations set by GitHub](https://help.github.com/en/actions/reference/events-that-trigger-workflows#triggering-new-workflows-using-a-personal-access-token).
|
||
|
||
> When you use the repository's GITHUB_TOKEN to perform tasks on behalf of the GitHub Actions app, events triggered by the GITHUB_TOKEN will not create a new workflow run. This prevents you from accidentally creating recursive workflow runs.
|
||
|
||
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 step.
|
||
|
||
```yaml
|
||
- uses: actions/checkout@v2
|
||
with:
|
||
token: ${{ secrets.PAT }}
|
||
```
|
||
|
||
If you work in an organization and don't want to create a PAT from your personal account, we recommend using a [robot account](https://docs.github.com/en/github/getting-started-with-github/types-of-github-accounts) for the token.
|
||
|
||
|
||
### Using the Action in forks from public repositories
|
||
|
||
By default, this Action will not run on Pull Requests which have been opened by forks. (This is a limitation by GitHub, not by us.)
|
||
|
||
If you want that a Workflow using this Action runs on Pull Requests opened by forks, 2 things have to be changed:
|
||
|
||
1. In addition to listening to the `pull_request` event in your Workflow triggers, you have to add an additional event: `pull_request_target`. You can learn more about this event in [the GitHub docs](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#pull_request_target).
|
||
2. GitHub Action has to be enabled on the forked repository. \
|
||
For security reasons, GitHub does not automatically enable GitHub Actions on forks. The user has to explicitly enable GitHub Actions in the "Actions"-tab of the forked repository. (Mention this in your projects README or CONTRIBUTING.md!)
|
||
|
||
After you have added the `pull_request_target` to your desired Workflow and the forked repository has enabled Actions and a new Pull Request is opened, the Workflow will run **on the forked repository**.
|
||
|
||
Due to the fact that the Workflow is not run on the repository the Pull Request is opened in, you won't see any status indicators inside the Pull Request.
|
||
|
||
#### Example
|
||
|
||
The following workflow runs `php-cs-fixer` (a code linter and fixer for PHP) when a `pull_request` is opened. We've added the `pull_request_target`-trigger too, to make it work for forks.
|
||
|
||
```yaml
|
||
name: Format PHP
|
||
|
||
on: [pull_request, pull_request_target]
|
||
|
||
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
|
||
with:
|
||
commit_message: Apply php-cs-fixer changes
|
||
```
|
||
|
||
Next time a user forks your project **and** enabled GitHub Actions **and** opened a Pull Request, the Workflow will run on the the forked repository and will push commits to the same branch.
|
||
|
||
Here's how the Pull Request will look like:
|
||
|
||
|
||
|
||
|
||
As you can see, your contributors have to go through hoops to make this work. For Workflows which runter linters and fixers (like the example above) we recommend running them when a push happens on the `master`-branch.
|
||
|
||
|
||
For more information about running Actions on forks, see [this announcement from GitHub](https://github.blog/2020-08-03-github-actions-improvements-for-fork-and-pull-request-workflows/).
|
||
|
||
### Push to forks from private repositories
|
||
|
||
By default, GitHub Actions doesn't run Workflows on forks from private repositories. To enable Actions for **private** repositories enable "Run workflows from pull requests" in your repository settings.
|
||
|
||
See [this announcement from GitHub](https://github.blog/2020-08-03-github-actions-improvements-for-fork-and-pull-request-workflows/) or the [GitHub docs](https://docs.github.com/en/github/administering-a-repository/disabling-or-limiting-github-actions-for-a-repository#enabling-workflows-for-private-repository-forks) for details.
|
||
|
||
### Signing Commits & Other Git Command Line Options
|
||
|
||
Using command lines options needs to be done manually for each workflow which you require the option enabled. So for example signing commits requires you to import the gpg signature each and every time. The following list of actions are worth checking out if you need to automate these tasks regulary
|
||
|
||
- [Import GPG Signature](https://github.com/crazy-max/ghaction-import-gpg) (Suggested by [TGTGamer](https://github.com/tgtgamer))
|
||
|
||
|
||
## Troubleshooting
|
||
### Action does not push commit to repository
|
||
|
||
Make sure to [checkout the correct branch](#checkout-the-correct-branch).
|
||
|
||
### Action does not push commit to repository: Authentication Issue
|
||
|
||
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.
|
||
|
||
### Push to protected branches
|
||
|
||
If your repository uses [protected branches](https://help.github.com/en/github/administering-a-repository/configuring-protected-branches) you have to do the following changes to your Workflow for the Action to work properly.
|
||
|
||
You have to enable force pushes to a protected branch (See [documentation](https://help.github.com/en/github/administering-a-repository/enabling-force-pushes-to-a-protected-branch)) and update your Workflow to use force push like this.
|
||
|
||
```yaml
|
||
- uses: stefanzweifel/git-auto-commit-action@v4
|
||
with:
|
||
commit_message: Apply php-cs-fixer changes
|
||
push_options: --force
|
||
```
|
||
|
||
In addition, you have to create a new [Personal Access Token (PAT)](https://github.com/settings/tokens/new),
|
||
store the token as a secret in your repository and pass the new token to the [`actions/checkout`](https://github.com/actions/checkout#usage) Action step.
|
||
|
||
```yaml
|
||
- uses: actions/checkout@v2
|
||
with:
|
||
token: ${{ secrets.PAT }}
|
||
```
|
||
You can learn more about Personal Access Token in the [GitHub documentation](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token).
|
||
|
||
Note: If you're working in an organisation and you don't want to create the PAT from your personal account, we recommend using a bot-account for such tokens.
|
||
|
||
### No new workflows are triggered by the commit of this action
|
||
|
||
This is due to limitations set up by GitHub, [commits of this Action do not trigger new Workflow runs](#commits-of-this-action-do-not-trigger-new-workflow-runs).
|
||
|
||
## Running the tests
|
||
|
||
The package has tests written in [bats](https://github.com/bats-core/bats-core). You can run them with the following command.
|
||
|
||
```shell
|
||
npm run test
|
||
```
|
||
|
||
## Versioning
|
||
|
||
We use [SemVer](http://semver.org/) for versioning. For the versions available, see the [tags on this repository](https://github.com/stefanzweifel/git-auto-commit-action/tags).
|
||
|
||
We also provide major version tags to make it easier to always use the latest release of a major version. For example you can use `stefanzweifel/git-auto-commit-action@v4` to always use the latest release of the current major version.
