diffsitter is a Rust CLI diff tool that computes diffs on the abstract syntax tree of source files using tree-sitter parsers, producing semantically meaningful output that ignores formatting differences like spacing. It supports languages such as Rust, Python, Go, Java, C++, TypeScript, and others covered by tree-sitter.

Use cases

• compare two source files ignoring whitespace and formatting changes
• get semantic diffs for code reviews instead of noisy text diffs
• diff refactored code where functions were reformatted
• filter which AST nodes are considered in a diff via config
• diff code in languages supported by tree-sitter

When to choose

• you want diffs based on code structure rather than raw text
• formatting-only changes are polluting your diffs
• your language is among the supported tree-sitter grammars

When to avoid

• you need a production-ready, battle-tested diff tool
• your language is not supported by tree-sitter
• you need diffing of non-source files like plain text or data files
