Supported Languages

RepoRelay uses tree-sitter for code parsing and a custom parser for Markdown.

Language	Parser	Extracted Symbols
TypeScript / JavaScript	tree-sitter	Functions, classes, interfaces, types, enums, methods, exports
Python	tree-sitter	Functions, classes, methods, decorators
Go	tree-sitter	Functions, structs, interfaces, methods
Java	tree-sitter	Classes, interfaces, methods, enums
Kotlin	tree-sitter	Classes, objects, functions, data classes
Rust	tree-sitter	Functions, structs, enums, traits, impls
C	tree-sitter	Functions, structs, enums, typedefs
C++	tree-sitter	Functions, classes, structs, namespaces
Markdown	Custom	Headings, code blocks, links

How Parsing Works

Each language has a dedicated extractor in src/parser/languages/. The unified tree-sitter pipeline:

1. Loads the appropriate grammar for the file's language
2. Parses the file into an AST
3. Walks the AST using language-specific queries to extract symbols and imports
4. Returns structured ParsedSymbol and ParsedImport objects

Unsupported file types (.json, .png, .lock, etc.) are silently skipped — they don't produce ref_files entries.
