I've developed a CoreFoundation reactor for Twisted that would
facilitate this sort of thing. It's not mainline yet because I haven't
had time to fully test and write enough examples -- it does work, but
I'm not currently comfortable putting it in the rest of Twisted yet
(especially due to the Pyrex build dependency).
Here's what you would do (this obviously needs Developer Tools
Download Pyrex 0.8.2
Modify Pyrex/Compiler/Nodes.py .. change the block starting on line 160
to this (small fix to allow system includes):
for filename in env.include_files:
if not (filename.startswith('<') and filename.endswith('>')):
filename = '"%s"' % filename
code.putln('#include %s' % filename)
Checkout CVS HEAD of Twisted
Build and install Twisted (or put twisted into your PYTHONPATH, I have
a symlink of ~/src/Twisted/twisted at
Go into Twisted/sandbox/etrepum/cfsupport
python setup.py build_ext -i
ln -s TWISTEDCVS/sandbox/etrepum/cfreactor.py .
ln -s TWISTEDCVS/sandbox/etrepum/cfsupport/cfsupport.so .
That should work, to test it check out the examples in
TWISTEDCVS/sandbox/etrepum/examples/PyObjC (which obviously require
PyObjC, you can get that from PackageManager)
Also note that the cfsupport module is enough to just get notifications
on the fd, but I recommend using Twisted for anything that talks
