I am thinking of using PyCXX principally for embedding Python. Here is some
basic code for embedding that I intend to use:
****************************************************************
#include <Python.h>
int main(int argc, char *argv[])
{
PyObject *pName, *pModule, *pDict, *pFunc, *pValue;
if (argc < 3)
{
printf("Usage: exe_name python_source function_name\n");
return 1;
}
// Initialize the Python Interpreter
Py_Initialize();
// Build the name object
pName = PyString_FromString(argv[1]);
// Load the module object
pModule = PyImport_Import(pName);
// pDict is a borrowed reference
pDict = PyModule_GetDict(pModule);
// pFunc is also a borrowed reference
pFunc = PyDict_GetItemString(pDict, argv[2]);
if (PyCallable_Check(pFunc))
{
PyObject_CallObject(pFunc, NULL);
} else
{
PyErr_Print();
}
// Clean up
Py_DECREF(pModule);
Py_DECREF(pName);
// Finish the Python Interpreter
Py_Finalize();
return 0;
}
**********************
I assume the above will work. Is there a more PyCXX way of doing this?
Lastly, I need to have callbacks into C++ code from Python. The Callable
interface is documented, but samples. Can someone please post examples of
how to use it?
