Re: [Caml-list] combining camlp4 extensions

[Pietro Abate <Pietro.Abate@anu.edu.au>]

There's something magic about this list... as soon as I post something I
come up with a solution... must be the ocaml-guru karma reaching my
office... anyway...

This example now works as expected... 

Is this the best way of solving this problem ?

------------ ext_repeat.ml
open Pcaml
open Repeat (* <--------- I need to refer to the grammar entity declared
               in the common part to be able to extend it !!!!!! *)

let extend () =
    EXTEND
    GLOBAL: reexpr;
      reexpr: [[ e = expr -> e ]];
    END
;;
-----------

-----------repeat.ml
open Pcaml
let reexpr = Grammar.Entry.create Pcaml.gram "reexpr";;
let extend () =
    EXTEND
    GLOBAL: reexpr expr ;
      expr: LEVEL "expr1"
        [[ "repeat"; e1 = reexpr; "until"; e2 = expr ->
              <:expr< do { $e1$; while not $e2$ do { $e1$; } } >> ]];

      reexpr: [[]];
    END
;;
