Compare Clipboard with Active File

A minimalistic Visual Studio Code extension that lets you quickly compare clipboard contents as the "After" and the active file as the "Before" — opposite behavior of VS Code’s built-in "Compare Active File with Clipboard."

Perfect for reviewing updates from AI tools like ChatGPT and generating clean, meaningful diffs.

---

Features

• ✅ Clipboard = After (additions/changes in green)
• ❌ Active file = Before (deletions/original in red)
• ⚡ Instant command or hotkey-based launch
• 🎯 Designed for fast code reviews, patch pasting, and AI-assisted workflows

---

Installation

From a local .vsix package:

code --install-extension ./compare-clipboard-with-active-file-0.1.0.vsix

Tip:
You can build your own .vsix (see Build section) or install manually later when published.

---

Usage

1. Copy text you want to compare into your clipboard.
2. Open the target file in VS Code.
3. Trigger the command:
   • Open the Command Palette (Ctrl+Shift+P or Cmd+Shift+P) → search for Compare Clipboard with Active File, or
   • Press the shortcut Cmd+K Shift+C (Mac) or similar on Windows/Linux.

VS Code’s built-in diff view will open with the clipboard vs. file.

npm run build
