Pre-compiled tree-sitter grammars for 371 programming languages with Elixir bindings via Rustler NIF.

What This Package Provides

• Parser access — load a tree-sitter language parser by name without wiring individual grammar crates or packages.
• Code intelligence primitives — parse trees, functions, classes, imports, exports, symbols, docstrings, diagnostics, and syntax-aware chunks.
• Shared cache model — parsers are fetched and cached once, then reused by every call in the process.
• Same catalog as every binding — Rust, Python, Node.js, Go, Java, PHP, Ruby, .NET, Elixir, WASM, Dart, Kotlin Android, Swift, Zig, and C FFI use the same grammar set.
• BEAM package — Rustler NIF binding for parser calls inside Elixir systems.

Installation

Add to mix.exs:

defp deps do
  [
    {:tree_sitter_language_pack, "~> 1.15.7"}
  ]
end

Quick Start

config_value = %TreeSitterLanguagePack.ProcessConfig{language: "python"}
result = TreeSitterLanguagePack.process("\# A comment\ndef greet(name):\n    \"\"\"Say hello.\"\"\"\n    return f'Hi {name}'\n\nimport os\n", config_value)
IO.inspect(result.language)
IO.inspect(result.structure)
IO.inspect(Enum.at(result.structure, 0).kind)
IO.inspect(result.imports)
IO.inspect(result.metrics.total_lines)
IO.inspect(result.metrics.error_count)

Features

• 371 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 — native APIs across 15 languages: Rust, Python, TypeScript/Node.js, Go, Java, C#, Ruby, PHP, Elixir, WebAssembly, Dart, Kotlin, Swift, Zig, and C/C++ via alef.
