Does anybody have yacc and lex files for a reasonable 6502 assembly grammar? Also, how would you implement macros with yacc/lex? Thanks |

Lex and Yacc are utilities (originally from unix) for defining a language grammar and lexigraphic analyzer. With a simple syntax, you feed yacc with a language grammar, lex with language tokens, and together, they generate C code to parse text files. -ss |

lex is short for Lexical Analyzer and yacc stands for Yet Another Compiler Compiler. There are GNU versions of these utilities called flex and bison. |
