Re: [Swig-devel] Re: %rename and the "name" test case

[Marcelo M. <mm...@ac...>]

Yes, the %rename is fixed now for the other languages that don't add a 
namewarn.
(it was a very silly problem).

So, please use it, for example you can add in your language and add new 
encodings, for
example:

/* create encoding for enum names in lisp */
String *Swig_string_lispid(String *s) {
  /* do something with the enum name */
    String *res = Copy(s);
    Replaceall(res,"-", "_");
    return res;
}

 guile::main() {
...
  /* register the encoding */
  DohEncoding("lispid",Swig_string_lispid);
..
}

then you can the following %rename:

   /* use the 'lispid encoding' */
   %rename("c-enum-%(lispid)s",match=enumitem) "";

   enum Hello {
      hi_there;               ->  renamed to "c-enum-hi-there"
      whats_up;             -> also renamed to "c-enum-whats-up"
   };

   int hi_there() {}       -> no renamed


nice, right?

The same way we can add a "regular expression" encoder, any voluunter?, 
the only thing
we need is a regexp library and write a small encoder function as the 
above, well, more
like the Swig_string_command (misc.c), but the idea is the same.
