This GitHub action enables automerge on pull requests opened by a specific author (defaulting to dependabot).

With automerge enabled, after required checks have completed, the target pull request will automatically be merged using the chosen merge method.

This workflow works by leveraging a personal access token via encrypted secrets. This means that anyone with collaborator access to your repository can enable automerge for PRs via this action if it is installed on your repository. Use with caution.

• You need to allow automerge on pull requests for your chosen repository. Instructions for doing so can be found in GitHub’s documentation.
• It’s also recommended that you enable branch protection rules for required status checks and/or requiring branches to be up-to-date before merging. Information about branch protection rules can be found in GitHub’s documentation.
• You’ll need to provide a personal access token to the action rather than the provided GITHUB_TOKEN environment variable. It’s recommended that you generate a personal access token and then add it as a repository secret.
  Why do I need to provide a PAT instead of `GITHUB_TOKEN`?

  This is because enabling automerge is only allowed by users with `repo` write-level access. The `GITHUB_TOKEN` env variable has limited permissions and doesn’t permit changing the automerge status of a pull request.

Configure this action to run on the pull_request event. Here’s an example workflow.yml:

name: Enable automerge on dependabot PRs

on:
  pull_request:

jobs:
  merge-me:
    name: Enable automerge on dependabot PRs
    runs-on: ubuntu-latest
    steps:
      - name: Enable automerge on dependabot PRs
        uses: daneden/enable-automerge-action@v1
        with:
          github-token: ${{ secrets.PERSONAL_ACCESS_TOKEN }}

          # The name of the PR author to enable automerge for
          # Defaults to dependabot
          allowed-author: dependabot

          # Allowed values: MERGE | SQUASH | REBASE
          # Defaults to MERGE
          merge-method: MERGE
