tree-sitter-clean

Clean grammar for tree-sitter.

Description

Clean is a general-purpose, purely functional programming language with uniqueness typing. This grammar supports:

• Module system (module, import, from...import)
• Type system (::, algebraic data types, records, type classes)
• Functions (named, guards, where/with clauses)
• Patterns (variables, constructors, wildcards, lists, tuples)
• Expressions (application, infix operators, let, case, lambda)
• Comprehensions (list comprehensions with generators, guards, let qualifiers)
• Records (construction, update, field access)

Node Types

The grammar produces 69 named node types for precise AST analysis, including:

• application — function/constructor call detection
• field_access — record field access
• list_comprehension — with generator, guard, let_qualifier
• record_expression / record_update — record manipulation
• wildcard — _ pattern

Usage

Rust

let mut parser = tree_sitter::Parser::new();
parser.set_language(&tree_sitter_clean::LANGUAGE.into())?;

JavaScript

const Parser = require("tree-sitter");
const Clean = require("tree-sitter-clean");
const parser = new Parser();
parser.setLanguage(Clean);

Python

import tree_sitter_clean
