diffy
2025
A fast command-line diff checker written in Rust that compares two text files using the Longest Common Subsequence (LCS) algorithm.
Overview
diffy is a lightweight and performant command-line utility built entirely in Rust. It efficiently computes differences between two text files by implementing the classic Longest Common Subsequence (LCS) algorithm and presents the results with clear color-coded output — green for added lines and red for removed lines.
The tool is designed for simplicity and speed, supporting optional line numbering and easy installation via Cargo. Perfect for quick file comparisons during development or code reviews.
