On ocamlyacc, function application grammar and precedence
- by Amadan
I'm OCaml newbie and I'm trying to write a simple OCaml-like grammar, and I can't figure this out. My grammar allows something like this:
let sub = fun x -> fun y -> x - y;;
However, if I want to use the function so defined, I can write: (sub 7) 3 but I can't write sub 7 3, which really bugs me. For some reason, it gets interpreted as if I wrote sub (7 3) (which would treat 7 as a function with argument 3). The relevant sections are:
/* other operators, then at the very end: */
%left APPLY
/* ... */
expr:
/* ... */
| expr expr %prec APPLY { Apply($1, $2) }
Thanks!
