Question

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.

No, that’s not possible with flex (I’ve already looked up flex sources once to find this out).

Strictly speaking, the question is a bit misleading, since you’re talking about a name definition, not rule.
