Why tree-sitter-language-pack

Parse any language without wiring up grammars

One install covers 306 languages — Python, Rust, Go, Java, TypeScript, C++, Kotlin, Swift, Zig, Elixir, Haskell, Julia, R, and hundreds more. Nothing to compile, nothing to fetch by hand.

Fast enough for real-time tooling

Parsing keeps up with editor keystrokes and large-repo scans, so you can build linters, formatters, and analysis that respond instantly.

Only download the parsers you use

The base install stays small. Each parser is fetched and cached the first time you touch its language, so you never ship 305 grammars you don’t need.

Find functions, classes, and imports in one call

Go past raw syntax trees: pull functions, classes, imports, exports, symbols, comments, and docstrings out of any file with a single call.

Chunk code your LLM can actually use

Split source at real boundaries — functions, classes, blocks — so each chunk stays whole for embeddings and prompt windows instead of cutting mid-statement.

Use your language's own parser types

In Python, Node.js, Go, Java, C#, Kotlin, Swift, Zig, and C, get_language() hands back your ecosystem’s native Language object, ready to pass to your existing parser.

Quick example

Python

Python

import tree_sitter_language_pack as tslp

# Parsers download automatically on first use
result = tslp.process(
    "def hello():\n    print('world')\n",
    tslp.ProcessConfig(language="python", structure=True, imports=True),
)

print(f"Language: {result.language}")
print(f"Functions: {len(result.structure)}")

Node.js

Node.js

import { process } from "@xberg-io/tree-sitter-language-pack";

const result = process("function hello() { console.log('world'); }", {
  language: "javascript",
  structure: true,
  imports: true,
});

console.log(`Language: ${result.language}`);
console.log(`Functions: ${result.structure?.length ?? 0}`);

Rust

Rust

use tree_sitter_language_pack::{ProcessConfig, process};

fn main() -> anyhow::Result<()> {
    let config = ProcessConfig::new("rust").all();
    let result = process("fn main() { println!(\"hello\"); }", &config)?;

    println!("Language: {}", result.language);
    println!("Functions: {}", result.structure.len());
    Ok(())
}
