Hello Thomas, hello to all pypy-ers,

I'm sure you will be interested to know that the ctypes implementation of pypy has matured enough to be able to run the comtypes module, at least some of the examples I found on the web site: http://starship.python.net/crew/theller/comtypes/ See the copy of a pypy session below.

Really cool to hear this. I must say that I sometimes look over the commit messages in the pypy.cvs mailing list (via gmane) and I'm fascinated by the work with ctypes that is done there! What I fear is that the day is not far where you know much more than myself about ctypes ;-)

Not everything works, though. For example, the COMError exception does not give any message, some errors are caused by the alternate garbage collector of pypy (opposed to the determinism of reference counting), and I'm sure that I missed many important details... At least it is now possible to run the comtypes test suite: some tests even pass ;-)

Hey, I did not know that ctypes and comtypes where so intricate: ctypes obviously has features designed for comtypes only (OUT parameters...) and ctypes/__init__.py even tries to import comtypes.server.inprocserver!

But this was all fun, and I learned a lot about ffi and COM from reading the code. Thanks for these wonderful modules!

Python 2.5.2 (61966, Feb 17 2009, 13:39:17) [PyPy 1.0.0] on win32 Type "help", "copyright", "credits" or "license" for more information. And now for something completely different: ``who am I and if yes, how many?''

Cheers,

Fantastic! I wish I had time to use pypy or even participate, but there is no chance, unfortunately. -- Thanks, Thomas
