It didnt seem to do anything. First i wrote | rval '<' rval | rval '<' '<' rval %dprec 1 | rval '>' rval %dprec 1 | rval '>' '>' rval
than after not getting the results i tried adding %dprec 2 to the other two lines. Then i changed one to 3s wondering if that would solve it. All in all it didnt seem to do anything :| is it because i already have precedence rules on '<' and '>'? I than tried moving the above out of my main expression and doing something similar with your sum/prod example. The problem is if i hide rval in the prod (pretend i'm doing addition/multiplication) I 1) have to go straight to literals which means higher precedence wont work because i'm not using rval 2) use rval which would break everything because you cant have a rval rval in the language and actually that rule would mean rval+ where + means one or more 3) rewrite all my rules to be like the prod/sum example. The expr rule (am i calling it right?) is 150lines so that is going to be brutal to rewrite. The way i been checking if this works is by looking at 1>2< <3>4 and seeing if the left (and right) are both literals (vs an expression for failure). I checked with << and saw it pass. Than did < < and saw it fail with %prec, %dprec 1/3 (with the other having no dprec and a 2) crap. I have no idea how i can fix this without rewriting it all. If %left and %right seem to do things why doesnt %prec seem to do what i need. There must be a way? I'm just going to pretend i will have to rewrite this because now after going through the above i think i need to rewrite those 150+ lines which is going to be difficult.
