git-diff-copy (gdc)

A cross-platform CLI tool that copies files changed between two git commits into a destination folder while preserving the original directory structure.

Useful for creating patch archives, deployment packages, or auditing changes between specific versions of your project.

Features

• 📂 Preserves Directory Structure: Keeps files in their original relative paths.
• 🚀 Cross-Platform: Works on Windows, macOS, and Linux.
• 🌳 Git Aware: Validates git repository and commit hashes.
• 🛡️ Safe: Checks for file existence before copying (handles deleted files gracefully).
• ⚙️ Zero Config: Helper interaction guides you through the process.

Installation

Install globally via npm:

npm install -g git-diff-copy

Or run via npx without installation:

npx git-diff-copy

Usage

1. Open your terminal in a git repository.
2. Run the command:

   gdc

3. Follow the interactive prompts:
   • Destination folder name: Where to copy the files (e.g., dist-patch, deploy-v2).
   • First git commit hash: The starting point (older commit/base).
   • Second git commit hash: The ending point (newer commit/head).

Example

$ gdc
Destination folder name: my-patch
First git commit hash: a1b2c3d
Second git commit hash: e5f6g7h

Analyzing changes between a1b2c3d and e5f6g7h...
