Partial PR Merger

A precision tool for cherry-picking specific lines from a GitHub Pull Request and merging them into your target branch without the need to clone the repository locally.

🚀 Key Features

• Surgical Selection: Choose exactly which lines to merge from a PR.
  • Keep (Repo Version): Retain the original code (Red lines).
  • Add (PR Version): Apply the new changes (Green lines).
  • Smart Mutual Exclusion: Selecting a block of changes automatically handles conflicts, ensuring you don't merge duplicate logic.
• No-Clone Workflow: Operates entirely via the GitHub API. No git clone, no local storage overhead.
• Sidebar Navigation:
  • Click file names to smooth-scroll to changes.
  • Bulk Actions: Toggle entire files between "PR Version" and "Repo Version" with a single click.
  • Status Indicators: identifying partial or mixed selections at a glance.

📖 Usage Guide

1. Authentication:

   • Required Scope: repo (to read code and push commits).
   • Tip: Use the built-in Help ('?') link to generate one with the correct permissions.
   • Optional Storage: Check "Remember me" to store your token locally. Uncheck for a one-time session (token cleared on exit).

2. Analyze a Pull Request:

   • Paste the full URL of a GitHub PR (e.g., https://github.com/owner/repo/pull/123).
   • Click "Analyze".

3. Select Your Changes:

   • Master Toggle: Switch between "Block" (select entire chunks) and "Single" (select individual lines) modes globally.
   • Per-File Overrides: You can also toggle the mode for specific files individually.
   • The Left Sidebar shows all changed files. Click to jump to them.
   • Green Checkbox: Select to ADD the change from the PR.
   • Red Checkbox: Select to KEEP the original version (reject the change).

4. Merge:

   • Click "Merge Selected Lines".
   • The app will construct a new commit on the target branch with only your selected changes and push it to GitHub.
