pa_macro + ulex

pa_macro + ulex

[Anastasia Gornostaeva]

Hello.

Is it possible to combine pa_macro and pa_ulex?

=== ex.ml ===

IFDEF VALUE1 THEN
let regexp something1 = [^"1"]
   ELSE
let regexp something2 = [^"2"]
let regexp something3 = "abc"
ENDIF

let rec somewhat = lexer
   | IFDEF VALUE1 THEN 
     something1+
    ELSE
     something2+ | something3
    ENDIF -> ()

   | _ -> failwith "Unknown one"


bash-2.05b$ ocamlfind ocamlc -syntax camlp4o -ppopt pa_macro.cmo -package ulex -c ex.ml
