GitHub PR Autofill

A Chrome extension that automates filling GitHub Pull Request forms based on branch naming conventions and predefined configuration.

Overview

The extension integrates with the GitHub Pull Request creation page and provides a “Fill PR” button.
When triggered, it extracts metadata from the current branch name and applies configured settings to populate PR fields automatically.

Features

• Branch Name Parsing – Extracts issue identifiers from branch names (e.g., feature/PROJ-1234, bugfix/APP-567).
• Template-Based Description – Inserts a PR description template.
• Automatic Reviewer Assignment – Adds reviewers specified in the extension settings.
• Assignee Handling – Optionally assigns the PR author automatically.
• Configurable Settings – Supports customization of issue tracker URLs and reviewer lists through the settings panel.

Workflow

1. Navigate to GitHub’s Pull Request comparison page.
2. Click the “Fill PR” button added by the extension.
3. The extension performs the following actions:
   • Parses the source branch name.
   • Extracts the issue key (if available).
   • Populates the PR title and description based on the issue key and template.
   • Assigns reviewers according to configured rules.

Configuration

Settings are available in the extension options page:

• Issue Tracker URL – Base URL for linking issue keys (e.g., JIRA, Linear).
• Default Reviewers – List of GitHub usernames to assign automatically.

Requirements

• Chrome browser
• GitHub account with access to the relevant repositories
• Branch naming convention following the pattern type/issue_key

Notes

• The extension operates client-side via DOM interaction; it does not modify GitHub server behavior.
• Intended for teams that maintain consistent branch naming and PR formatting practices.
