Supported Languages

Tree-sitter-language-pack supports 306 languages. Parsers download on demand via ts-pack download <language> or automatically on first use.

Language List¶

Language aliases¶

Some common alternative names resolve to the canonical grammar name:

Aliases work anywhere a language name is accepted: API calls, CLI arguments, config files.

Language groups¶

Groups let you download a related set of parsers in one command:

ts-pack download --groups web,systems

Available groups: web, systems, scripting, data, jvm, functional.

Group membership is defined in the release manifest. To see which languages a group includes, check the release manifest for your version.

Checking language availability¶

from tree_sitter_language_pack import has_language, available_languages, language_count

print(has_language("python"))      # True
print(has_language("brainfuck"))   # False
print(language_count())            # 306

for lang in sorted(available_languages()):
    print(lang)

import { hasLanguage, availableLanguages, languageCount } from "@kreuzberg/tree-sitter-language-pack";

console.log(hasLanguage("python"));     // true
console.log(languageCount());           // 306

for (const lang of availableLanguages().sort()) {
  console.log(lang);
}
