std::vector to boost::python::list

boost::python already includes functionality for wrapping vectors and maps. Here’s sample code for vectors, as you can see both passing and returning lists is quite simple:

// C++ code
typedef std::vector<std::string> MyList;
class MyClass {
  MyList myFuncGet();
  void myFuncSet(const Mylist& list);
  //       stuff
};

// Wrapper code

#include <boost/python/suite/indexing/vector_indexing_suite.hpp>

using namespace boost::python;


BOOST_PYTHON_MODULE(mymodule)
{
    class_<MyList>("MyList")
        .def(vector_indexing_suite<MyList>() );

    class_<MyClass>("MyClass")
        .def("myFuncGet", &MyClass::myFuncGet)
        .def("myFuncSet", &MyClass::myFuncSet)
        ;
}

Maps are very similar to vectors and are described in this post:
Boost::Python- possible to automatically convert from dict –> std::map?

Unfortunately boost::python does not currently include facilities for wrapping lists. You can create the wrapper manually, but I’m out of time for this answer. I can post it today or tomorrow. I’d appreciate a new question about this particular problem, because the answer will be quite extensive and is probably outside of the scope of this post. I’d just avoid lists and use vectors instead.
