%typemapping of a C++ Library for Python Interface

Question

I want to create a python wrapper for my C++ library. It would be cool, if there is a automatic conversion of std::vector to python lists and the other way round. Unfortunatly

Answer 1

If you're going to define the %typemaps manually, you will also need a %typemap(check), something like:

%typemap(typecheck) std::vector& {
    $1 = PySequence_Check($input) ? 1 : 0;
}

I believe the rule of thumb is that if you define a %typemap(in), you should also define a %typemap(check) --- otherwise, the generated code never gets to where it's put your %typemap(in).
