A Beginner's (probably stupid) Question

[arief_mulya]

Dear all,



Sorry to bother you all about this simple (stupid?) question 
of mine.

How do exactly one do interconnection between flex and 
bison? I mean, how do the two interconnect with each other?

I've been reading flex manual. And a little bit of bison's 
(I'm no CS student or professor, so terms like 
LALR/reduce/reduce automata etc, confuses me, and sleeps me 
:-( everytime I try to read bison info pages..), but I still 
haven't found a clear view on practice.

I know that flex provice yylex function, but suppose I want 
to return a string and a token to bison, how do I do that? 
and how do I connect the two source file? do I need to 
include a header in one or the other file(s)? which header 
should I use.

I have able to make some simple lexer using flex. But 
haven't make one parser using bison. I learn these two tools 
because I like to have an extensible parser using C, but I 
don't like to create a customized function everytime a new 
format appears. (Kind of tiresome, these days... )

Please accept my apology for this disturbance.


Best Regards,
