NOTE: Sadly this code isn't working 100% correctly, I have a new versions which I will add here soon
| Code: Converting your custom class to a python usable class |
CustomString* factory(const char* str){
return new CustomString(str);
}
struct CustomString_to_PyStr: to_python_converter<CustomString*, CustomString_to_PyStr> {
static PyObject* convert(CustomString* x) {
return PyString_FromString(x->c_str());
}
};
void* extract_CustomString(PyObject* op){
return CustomString::stringWithCString(PyString_AsString(op));
}
BOOST_PYTHON_MODULE(Foo){
CustomString_to_PyStr();
boost::python::converter::registry::insert(&extract_CustomString, boost::python::type_id<CustomString>());
}

With this code we can convert to and from a custom string class. In python we use the regular strings and in C++ we can use our custom string class. This would work with any class of course.
