tree-sitter-gosu

A Tree-sitter grammar that parses Gosu, a statically typed, JVM-based general-purpose programming language.

Requirements

• Python >=3.14
• Poetry 2.2
• Node.js (for tree-sitter-cli, used to regenerate the parser from grammar.js)
• A C compiler (MSVC on Windows, GCC/Clang on Linux/macOS) to build the native extension and run tree-sitter test/tree-sitter parse

Installation

poetry install

import tree_sitter_gosu

language = tree_sitter.Language(tree_sitter_gosu.language())
