dependencies {
    implementation("dev.kreuzberg.treesitterlanguagepack:tree-sitter-language-pack:1.7.0")
}

dependencies {
    implementation 'dev.kreuzberg.treesitterlanguagepack:tree-sitter-language-pack:1.7.0'
}

Verify:

import dev.kreuzberg.TreeSitterLanguagePack;

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

Ruby

Requires Ruby 3.2+.

gem install tree_sitter_language_pack

gem "tree_sitter_language_pack", "~> 1.0"

bundle install

Verify:

require "tree_sitter_language_pack"

puts TreeSitterLanguagePack.language_count # 306

Elixir

Requires Elixir 1.14+ and OTP 25+.

defp deps do
  [
    {:tree_sitter_language_pack, "~> 1.0"}
  ]
end

        "kreuzberg/tree-sitter-language-pack": "^1.0"
    }
}

Verify:

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

WebAssembly

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