## a structural diff tool that understands syntax

GitHub 📖 Manual 🚦 Install

Difftastic is a CLI diff tool that compares files based on their syntax, not line-by-line. Difftastic produces accurate diffs that are easier for humans to read.

## Understand What Actually Changed

Difftastic parses your code with tree-sitter. Unlike a line-oriented text diff, difftastic understands that the inner expression hasn't changed here.

## Ignore Formatting Changes

Has your code formatter decided to split something over multiple lines? Difftastic can show what has actually changed.

## Visualise Wrapping Changes

Have you added a wrapper? Difftastic can match the delimiters exactly.

Even if you change the inner content, difftastic can still show you the additional wrapper.

## Real Line Numbers

Do you know how to read `@@ -5,6 +5,7 @@` syntax? Difftastic shows the actual line numbers from your files, both before and after.
