porting vc++ project to python?

[marco Starglider]

hi,

i have a very large project in visual studio2005->visual c++ in windowsxp.
i'd like to port it, or my next project, over to python.
is this possible without rewriting all my code?
are there multiple options to do this?
my project is so large, that entirely rewriting it
is actually no option.

regards,

m

ps i guess, it's an option to transform my current code into one or more
python extensions/modules, and then calling them from a python core
module?

You have a couple of options, but it really depends on the structure
of your program.

Option 1: You could encapsulate the important portions of your code in
DLLs and access them from python using the ctypes module.

Option 1b: You could encapsulate the important portions of your code
as COM DLLs and access them from win32com.

Option 2: You could turn your code into python extensions (DLL):
http://docs.python.org/ext/

Option 3: You could rewrite portions of your code in python and access
it from VC++: same as before - http://docs.python.org/ext/

It all depends on how your project is structured, and what you
consider to be the most difficult part to convert. If your app has a
complex user interface and that is the most difficult part to convert
then option 3 is probably best. If the code is well encapsulated and
the user interface will be easy to rewrite then options 1 or 2 will
work best. It is probably best to stay away from 1b unless portions of
your stuff already exist as COM DLLs. If you do have COM DLLs however,
accessing them from Python is very easy.

Clients of mine have had very good results wrapping C++ functionality
with Boost (http://www.boost.org/libs/python/doc/). It might work for
you too.

It is. I personally prefer SIP, which is a C++ wrapper generator used to
wrap the Qt toolkit. But there are other options as well, e.g. SWIG and
Boost:ython.
