difftastic

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

actual line numbers from your files, both before and after.
