ripdiff

A terminal-based directory comparison tool built with Rust and Ratatui.

Description

ripdiff is a fast, parallel file tree diffing tool that displays directory differences in an interactive terminal UI. It compares two directories side-by-side, allowing you to navigate file trees and view file contents directly in your terminal.

Features

• Parallel file discovery - Uses rayon and ignore for fast directory traversal
• Side-by-side comparison - View file contents from both directories simultaneously
• Interactive TUI - Navigate file trees with keyboard controls
• Real-time file viewing - Open and scroll through file contents
• Expandable directory tree - Navigate nested folder structures on-the-fly

Installation

cargo build --release

Usage

ripdiff <old_directory> <new_directory>

Keybindings
