All bindings expose a unified process() function for extracting structured intelligence from source code:
| Language | Function |
|---|---|
| Rust | ts_pack_core::process(source, &config) |
| Python | process(source, ProcessConfig(...)) |
| Node.js | process(source, { language: '...' }) |
| Go | registry.Process(source, config) |
| Java | registry.process(source, configJson) |
| Ruby | TreeSitterLanguagePack.process(source, configJson) |
| Elixir | TreeSitterLanguagePack.process(source, configJson) |
| WASM | process(source, { language: '...' }) |
| C FFI | ts_pack_process(registry, source, len, configJson) |
The process() function returns structured analysis including functions, classes, imports, comments, and optionally chunked source segments.
| Feature | Description |
|---|---|
| 305+ Languages | Pre-compiled parsers for 305+ programming languages |
| On-Demand Downloads | Parsers are downloaded on-demand and cached locally for fast reuse |
| Selective Installation | Download only the languages you need; unused parsers never downloaded |
| Polyglot Bindings | Native bindings for Rust, Python, Node.js, Go, Java, Elixir, and C/C++ |
| Automatic Caching | Downloaded parsers cached in platform-specific directories for offline use |
| CLI Tool | ts-pack download to pre-download parsers for offline/CI/Docker use |
