SWIG wrapping C++ for Python: translating a list of strings to an STL vector of STL strings

Question

I would like to wrap a C++ function with SWIG which accepts a vector of STL strings as an input argument:

#include 
#include 
#         


        

Answer 1

You need to tell SWIG that you want a vector string typemap. It does not magically guess all the different vector types that can exist.

This is at the link provided by Schollii:

//To wrap with SWIG, you might write the following:

%module example
%{
#include "example.h"
%}

%include "std_vector.i"
%include "std_string.i"

// Instantiate templates used by example
namespace std {
   %template(IntVector) vector;
   %template(DoubleVector) vector;
   %template(StringVector) vector;
   %template(ConstCharVector) vector;
}

// Include the header file with above prototypes
%include "example.h"
