Projects / LLnextgen


LLnextgen is a (partial) reimplementation of the LLgen Extended-LL(1) parser generator that is part of the Amsterdam Compiler Kit (ACK). It takes an EBNF-like description of the grammar with associated semantic actions in C as input, and generates C code. The generated code is strict ANSI C, so it should compile with all current C compilers.
