![]() The documentation that comes with Flex and BISON is also excellent, but no tutorial. This document is aimed at bootstrapping your use of Lex & YACC, to allow you to create your first programs. See the 'Further Reading' section at the end. They provide far more information than we ever will. By all means read these books if you need to know more. There are several great books which deal with Lex & YACC. YACC is really amazing when used in combination with Lex, however, the Bison manpage does not describe how to integrate Lex generated code with your Bison program. These programs are massively useful, but as with your C compiler, their manpage does not explain the language they understand, nor how to use them. We will call these programs Lex and YACC throughout - the newer versions are upwardly compatible, so you can use Flex and Bison when trying our examples. ![]() ![]() If you have been programming for any length of time in a UnixĮnvironment, you will have encountered the mystical programs Lex & YACC, or as they are known to GNU/Linux users worldwide, Flex & Bison, where Flex is a Lex implementation by Vern Paxson and Bison the GNU version of YACC.
