Subject: [ruby-talk:17634] SWIG and strings

Hi,

  Has anybody been able to typemap strings in swig with ruby?


Given the .i file for swig:
%module example
class Test {
  public:
  string str;

  Test() {  str = "putz"; }
};

In Ruby:
  require 'example'
 c = Example::Test.new()

c.str  .... returns the following, not "putz"
#<Example::SWIG::TYPE_p_string:0x4029ad64>


In Perl we can add to the .i file the following


%typemap(ruby,out) string {
  $target = sv_newmortal();
  sv_setpv($target,((char *)$source->c_str()));
  argvi++;
}

Any ideas for writing the typemap for strings in ruby or is
there any reference material for swig and ruby on typemaps?
