SWIG and Python in use?

Hi,

I am considering scripting a large C++ application.

In particular I am interested in test driving and end-user scripting
the "applicatio n layer" in Python and giving it access to a large
collection of C++ objects and their methods.

I note that SWIG is a mature tool and refers to supporting Python
v1.x.

Has/Does anyone use SWIG to bind with Python 2.x ?.

Does it still work?
Any pitfalls, caveats ?

Thanks in advance.

I've used swig a little bit. It's very good to generate interfaces for
C librarys. It can build interfaces for a lot of languages not only
python.

To interface C++ there are some problems. Simple C++ clases are easy
to interface but if us use virtual methods, templates an so on that
possible with swig but you have to write a lot of wrapper code.
Not an easy task.

To interface the app to python 2.2 and above, consider to use
Boost.python: http://www.boost.org/libs/python/doc/index.html

Today I use Boost.python for my new projects. It's easy
to interface C++ librarys and all C++ stuff.
Less code to write and for me it's easier.
(I don't know the Python C Api in detail, with boost.python
I wrote a C++ interface for a database within 3 days)

Hi, I'm using Python in my win32 app by linking to the python23.dll. I'm trying to expose some c++ code in my app to Python so I can make application calls from Python scripts (according to the Python windows FAQ I shouldn't have to make a seperate dll, see link below). I create a MyModule.i file for swig which contains a simple test c++ class. I run swig on it with the following options: swig -python -c++ -includeall -shadow MyModule.i,...

Hi, I´m looking for some benchmarks comparing SWIG generated modules with modules made directly with C/Python API. Just how much overhead does SWIG give? Doing profile of my code I see, that it spends quiet some time in functions like _swig_setattr_nondinamic, _swig_setattr, _swig_getattr.

I have a bit of a odd arrangement here with SWIG, Python, Embedded Python and C++ classes exported into Python. Here's the plot: I have a class defined in a C++ DLL library. I am wrapping this class (we'll call it "Peter") with SWIG so some of its base functionality is available in Python. For the sake of this example, Peter has a method called get_type(), that takes no arguments and returns an integer. This all works, and within my...
