codemapper
codemapper (cm)
Maps symbols across your codebase using tree-sitter AST parsing. Everything runs in-memory — no databases. Supports Python, JavaScript/TypeScript, Rust, Java, Go, C, Swift, and Markdown.
Exploring an Unknown Codebase
Start with project overview, then drill down:
cm stats . # File counts, symbol breakdown, parse timing
cm map . --level 2 --format ai # File structure with symbol counts (compact)
cm query <symbol> # Find functions, classes, methods (fuzzy search)
cm inspect ./path/to/file # Deep dive into one file
