Using tree-sitter for entity-level code diffing and dependency graphs I've been researching entity-level diffing as an alternative to line-level diffs. The idea: use tree-sitter grammars to extract structural entities (functions, classes, methods) from source code, then build a cross-file dependency graph by resolving references between them. traditional diff tools compare lines, but the meaningful unit of change in code is an entity. When you rename a function, move a method, or reformat a file, line-level diff produces noise. Entity-level diff tells you "this function was modified, this one was added, this one moved." The interesting technical bits: \- Each language gets a config that maps AST node types to entity types (e.g. function\_definition in Python, function\_item in Rust, method\_declaration in Java). Currently supports 25+ languages through tree-sitter.…
