We do the same thing here, we just use basic in/out typemaps.
E.g.
%typemap(out) YString
{
$result = PyString_FromString((char *)static_cast<const char *>($1));
}
%typemap(in) const YString &
{
$1 = new YString(PyString_AsString($input));
}

Subject: [Swig-user] Using own string class
Hello!
At ZNC we have an own string class CString, which is inherited from std::string.
The goal is to use it as a just string in target languages.
How to do that properly?
When I was writing modperl and modpython ZNC modules, I used an approach
described at http://old.nabble.com/Forward-declaration-error--td24064356.html
Used "swig -E" on std_string.i, got a long file as a result, cleaned it up and
changed all occurences of std::string to CString.
It worked fine before SWIG 2.0.5, but in 2.0.5 it started to give errors while
generating sources for modpython:
