Ask bison to generate a header file: bison --defines --debug python.y Use the generated header (which will be called python.tab.h) by putting this line in your lexer just below #include :
Bison is a general-purpose parser generator that converts an annotated context-free grammar into a deterministic LR or generalized LR (GLR) parser employing LALR(1) parser tables.
