Difftastic is a structural diff tool written in Rust that parses source files using syntax trees (via tree‑sitter) and produces human‑readable diffs at the expression level. It works across 30+ languages and emphasizes readability by aligning code structure rather than lines. Ideal for code review and understanding semantic changes.
Features
- AST‑based syntax-aware diffs (not just line diffs)
- Supports 30+ programming languages via tree‑sitter
- Highlights moved code segments, renamed variables
- Human‑friendly side‑by‑side terminal output
- Falls back to word‑based text diff for unknown files
- No patch generation or merging—focused solely on human understanding
