Rust

Pre-compiled tree-sitter grammars for 306 programming languages, with on-demand download and caching. Polyglot core that powers every binding in the kreuzberg.dev ecosystem.

Installation

cargo add tree-sitter-language-pack

Quick Start

use tree_sitter_language_pack::{get_language, get_parser};

let mut parser = get_parser("python").expect("language available");
let tree = parser.parse("def hello(): pass", None).unwrap();
println!("{}", tree.root_node().to_sexp());

Features

306 languages — pre-compiled tree-sitter grammars covering every major programming language and many minor ones.
On-demand download + cache — parsers fetched at first use; subsequent runs hit the local cache.
Code intelligence — extract functions, classes, imports, exports, symbols, docstrings, and diagnostics with one API.
Syntax-aware chunking — semantic chunks for RAG/LLM pipelines.
Polyglot bindings — Rust core with native bindings for Python, TypeScript, Go, Java, C#, Ruby, PHP, Elixir, and WebAssembly via alef.
