Usage

To use this GitHub Action in your workflow, create a YAML file (e.g., .github/workflows/update_pr.yml) in your repository with the following configuration:

name: Update PR Title

on:
  pull_request:
    types:
      - opened

jobs:
  update_pr_title:
    runs-on: ubuntu-latest

    steps:
      - name: Check out code
        uses: actions/checkout@v2

      - name: Update PR Title
        id: update_title
        uses: kigary/update-pr-from-branch-name@v1
        with:
          repo-token: ${{ secrets.GITHUB_TOKEN }}
          branch-prefix: feat,bugfix
          branch-prefix-separator: _
          issue-tracker-url: https://example.com/issues
          issue-ticket-regex: '([A-Z]+-\d+)'
          issue-ticket-separator: -
          issue-ticket-container-punctuation: square-brackets

      - name: Get PR Title
        run: echo "Updated PR Title: ${{ steps.update_title.outputs.pull-request-title }}"

In this example, the action will trigger when a pull request is opened. Customize the inputs to match your repository's naming conventions and requirements.

Behavior

The action checks if the provided branch-prefix matches the prefix in the branch name. If not, it fails the workflow.
It extracts the issue ticket number from the branch name using the specified issue-ticket-regex and issue-ticket-separator.
It normalizes the issue ticket summary by capitalizing the first letter and replacing separators with spaces.
The issue ticket URL is constructed using the issue-tracker-url and issue ticket number.
The PR title is updated with the issue ticket number enclosed in the specified container punctuation and the normalized summary.
The action appends the issue ticket URL to the PR body.
If the PR update is successful, relevant outputs are set for use in subsequent steps.

Conclusion

The Update Pull Request from Branch Name GitHub Action helps maintain consistency and traceability in your repository by automatically updating PR titles and bodies based on branch names. Customize the action's inputs to fit your project's naming conventions and requirements.
