How to organize python / boost python projects

Hereinafter pif stands for Python InterFace. First I have a common header file called conv_pif.hpp that has Boost headers and C ++ Std Library headers, etc. Then for each boost python module, I have a file (here is the corresponding genocpp example) of the form string_pif.cpp, where the line corresponds approximately to the name of the module.

****************************************************************************************
geno_pif.cpp
****************************************************************************************
#include "conv_pif.hpp"
#include <boost/python.hpp>
#include "geno.hpp"

void export_cppvec_conv();

void export_geno()
{
  boost::python::def("write_geno_table_affy6_to_file", write_geno_table_affy6_to_file);
}

BOOST_PYTHON_MODULE(genocpp)
{
  export_geno();
  export_cppvec_conv();
}
*****************************************************************************************

The export_cppvec_conv function matches a (templated) converter to / from C ++ vectors to python lists. I have the actual converters in the cppvec_conv_pif.cpp file. In particular, this defines export_cppvec_conv, which uses template conversion, so I can leave without including it in geno_pif.cpp. For illustration, the contents of export_cppvec_conv are as follows: cppvec_to_python_list and cppvec_from_python_list are defined in the body cppvec_conv_pif.cpp.

******************************************
cppvec_conv_pif.cpp (extract)
******************************************
void export_cppvec_conv()
{
  boost::python::to_python_converter<vector<double>, cppvec_to_python_list<double> >();
  cppvec_from_python_list<double>();

  boost::python::to_python_converter<vector<int>, cppvec_to_python_list<int> >();
  cppvec_from_python_list<int>();

  boost::python::to_python_converter<vector<string>, cppvec_to_python_list<string> >();
  cppvec_from_python_list<string>();
}
