Hi there i have a flex rule inside my lexer definition :

operators  "[]"|"[]="|"[]<"|".."|"."|".="|"+"|"+="|"-"|"-="|"/"|"/="|"*"|"*="|"%"|"%="|"++"|"--"|"^"|"^="|"~"|"&"|"&="|"|"|"|="|"<<"|"<<="|">>"|"!"|"<"|">"|">="|"<="|"=="|"!="|"&&"|"||"|"~="

Is there any way to split this ruole on more lines to keep it clearer? I tried with \ just like macros but it does not seem to be accepted by flex :(

PS: I don't want to split the rule in more sub-rules, but only split its regex in more lines to keep the code clearer.

I can't figure this one out. I can download a win32 binary of flex 2.5.4a from gnuwin32, but I'd like to build the latest version (2.5.35) using Visual Studio 2005. I suppose I could build in in cygwin, but where is the fun in that? http://flex.sourceforge.net/ >>> More
