moonbitlang/parser

Note: This module is highly experimental and unstable. Use with caution.

A parser implementation for the MoonBit programming language, written in MoonBit, providing lexical analysis and syntax parsing capabilities.

This module defines the Abstract Syntax Tree (AST) and provides parsers for MoonBit source code. It includes both a hand-written LL(k) parser with error recovery and an LR(1) parser generated by moonyacc.
