Installation

Install using the CLI¶

The ts-pack CLI allows you to manage parsers and run code analysis directly from your terminal. You can use it in CI pipelines, automation scripts, or to explore and experiment with 306 supported languages Available by v1.9.

brew trust kreuzberg-dev/tap
brew install kreuzberg-dev/tap/ts-pack

cargo install ts-pack-cli

ts-pack --version
ts-pack list | wc -l   # → 306

dependencies {
    implementation("dev.kreuzberg.treesitterlanguagepack:tree-sitter-language-pack:1.9.0-rc.49")
}

dependencies {
    implementation 'dev.kreuzberg.treesitterlanguagepack:tree-sitter-language-pack:1.9.0-rc.49'
}

Verify:

import dev.kreuzberg.treesitterlanguagepack.TreeSitterLanguagePack;

public class Main {
    public static void main(String[] args) {
        System.out.println(TreeSitterLanguagePack.languageCount()); // 306
    }
}

C# Available by v1.9¶

Requires .NET 10.

Verify:

using TreeSitterLanguagePack;

Console.WriteLine(TreeSitterLanguagePackConverter.LanguageCount()); // 306

The NuGet package includes native runtime assets for Windows, Linux, and macOS.

Ruby¶

Requires Ruby 3.2+.

gem install tree_sitter_language_pack

gem "tree_sitter_language_pack", "~> 1.9"

Elixir¶

Requires Elixir 1.14+ and OTP 25+.

defp deps do
  [
    {:tree_sitter_language_pack, "~> 1.9"}
  ]
end

mix deps.get

Verify:

IO.puts TreeSitterLanguagePack.language_count() # 306

PHP¶

Requires PHP 8.2+. This package is a native PHP extension (type: php-ext). Install mlocati/php-extension-installer first so Composer can download and register the compiled .so/.dll:

composer require mlocati/php-extension-installer

composer require kreuzberg-dev/tree-sitter-language-pack

{
    "require": {
        "mlocati/php-extension-installer": "^2.0",
        "kreuzberg-dev/tree-sitter-language-pack": "^1.9"
    }
}

Verify:

<?php
echo \ts_pack_language_count(); // 306

Dart¶

Requires Dart 3.11+.

dart pub add tree_sitter_language_pack

Kotlin Android Available by v1.9¶

Requires Android minSdk 21 and Java 17 bytecode.

implementation("dev.kreuzberg.tslp.android:tree-sitter-language-pack-android:1.9.0-rc.49")

This is an Android AAR. Kotlin/JVM users should use the Java artifact.

Swift¶

Requires Swift 6.0+.

.package(
    url: "https://github.com/kreuzberg-dev/tree-sitter-language-pack",
    exact: "1.9.0-rc.49"
)

Zig¶

Requires Zig 0.16+.

zig fetch --save <release tarball url>

The package name is tree_sitter_language_pack.

C FFI¶

Download the shared library and generated C header from GitHub Releases. The C FFI is the stable native contract used by the generated native packages.

WebAssembly¶

Use from any JavaScript environment — browsers, Deno, and Cloudflare Workers.

npm install @kreuzberg/tree-sitter-language-pack-wasm

<script type="module">
  import { availableLanguages, parseString } from "https://cdn.jsdelivr.net/npm/@kreuzberg/tree-sitter-language-pack-wasm/+esm";
  console.log(availableLanguages());
</script>

import { availableLanguages, parseString } from "npm:@kreuzberg/tree-sitter-language-pack-wasm";
console.log(availableLanguages());

The WASM package is a static curated subset of parsers compiled into the module. It does not expose the native download/cache helpers.

Next Steps¶

• Quick Start — parse your first file in 5 minutes
• Download parsers — pre-download grammars for production, CI, or offline use
• Download model — understand how parser caching works
• Languages — full list of 306 supported languages
