About the project

A C++ LALR(1) parser generator with an integrated lexer, UTF-8 support, and built-in AST construction and walking. It turns a grammar into a parser as separate .hpp/.cpp files or a single self-contained file with main().

Useful for

Generate a parser for a custom language or DSL from a grammar
Drop a generated parser into an existing C++ project as .hpp and .cpp
Parse a character stream from a socket via the push-based lexer
