Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes.

Diffing

Fixed crash on some textual files where a single change contained more than 1,000 words.

Parsing

Added support for device tree and F#.

Difftastic now uses tree-sitter comment highlighing as a hint that nodes should be treated as atoms. This ensures comments are treated more consistently across languages. This fixes cases in Elm where comment differences were ignored, and may improve other languages too.
