I'm not really sure, as I don't use win32 myself, but I've heard reports that
ipython can't be used with jython, because it lacks sys._getframe. Python
implementations that run on other virtual machines (Jython/IronPython) often
handle internals in a different manner, and don't expose enough of them for
ipython to operate.
abdul[IPython]> grep -n sys._getframe *py
background_jobs.py:160: frame = sys._getframe(1)
genutils.py:1039: frame = sys._getframe(1)
genutils.py:1612: call_frame = sys._getframe().f_back
iplib.py:1277: call_frame = sys._getframe(stack_depth).f_back
Itpl.py:214: frame = sys._getframe(1)
Magic.py:275: caller = sys._getframe(1).f_code.co_name.replace('magic_','')
While I'm sure some of these could be replaced with other functionality, I'm
not sure we can get rid of all and still get all the benefits of ipython.
IPython, while being pure python code (no C in there), exercises fairly
heavily the CPython internals.
I'd love to see ipython working with both of those, but I don't know how hard
it would be to make it happen, and not being a win32 user myself, I won't be
able to do that work. But I'd be at least interested in hearing from anyone
who knows more about this topic.
