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-Action of the Canadian Digital Service and this commit-Action by Eric Johnson.

This Action currently can't be used in conjunction with pull requests of forks. See issue #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.

- uses: stefanzweifel/git-auto-commit-action@v4.1.0
  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

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@v4.1.0
      with:
        commit_message: Apply php-cs-fixer changes
        branch: ${{ github.head_ref }}

Example on push event

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@v4.1.0
      with:
        commit_message: Apply php-cs-fixer changes

Inputs

Checkout 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. (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 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

You can change this by creating a new Pesonal Access Token (PAT), storing the token as a secret in your repository and then passing the new token to the actions/checkout Action.

Example Workflow

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@v4.1.0
      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 for more information.
