Integrate a python scripting console for a C++ library

Question

I have a library with classes and public methods written in C++.

I would like, from inside an interactive program written in C++ and Qt, to send commands to a parser in Python language which in turn converts them to call to methods and functions of my library.

Something similar to what is done in Octave/Matlab, a string is processed by a parser which then executes internally the commands.

Somewhere in my C++ library I have a function

int myFooCPPfunction(int value)
{
    return value*value;
}

then during the execution of my program, I want to start a console and type in Python syntax:

for i in range(0,20):
    print("%d" % myFooCPPfunction(i))

The command I gave then updates the internal state of my program for example.

I think it is a matter of writing Python code that links to C++. It seems to me that things like boost::python already do it...I ask your suggestion on which is the better way to write the bindings.

Second point: how to integrate that thing in an interactive shell launched from a Qt application? Some online projects like QConsole should do something similar, but QConsole appears to be a very outdated project.

Thank you!

PythonQt was created for exactly this purpose.

In particular the example PyScriptingConsole does the job I intended, thanks for the suggestion
