[C++-sig] Python scopes in C++

[Marc Lazareff]

Hello,

Our software uses Python bindings (through SWIG) for C++ "description" 
classes, implementing a data-oriented user interaction model.

These classes are data containers, managing attribute/value pairs 
through C++ maps, images of the corresponding Python dictionaries for 
Python "description" objects. C++ description objects themselves are 
"registered" with a global manager.

All goes well as long as we treat all entities in a unique, global, 
scope. But this mechanism does not respect Python scopes, because all 
objects are registered on the same level, so that :

import spam

and :

from spam import *

have equivalent results for the C++ data structure, which does not 
respect the Python scoping logic.

Thus we need to replicate in our C++ code the Python scopes mechanism.

I wondered if any of you had experience with a solution for this 
problem, maybe re-using the Python C code.

Thank you for any advice,
Marc Lazareff
