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.
