diffside

🧠 A side-by-side CLI diff tool with word-level coloring, Dracula theme, and scrollable paging.

diffside is a command-line utility written in Rust that compares two text files and shows their differences in a clean, side-by-side format. It highlights word-level changes with background colors and includes paging support for viewing large files easily.

✨ Features

• 🟥🟩 Word-level diff highlighting
• 📜 Side-by-side comparison with aligned line numbers
• 🎨 Built-in Dracula theme (no config needed)
• 📏 Automatic line wrapping and alignment
• 🔽 Paging support using less -R

🚀 Installation

Once published to crates.io:

cargo install diffside

🧪 Example

Compare two files:

diffside file1.txt file2.txt

Disable pager (for piping or scripting):

✅ No Diffs Case

When the files are identical, you'll see:

✅ No differences found between 'file1.txt' and 'file2.txt'.
