First of all, IPython, being pure Python code, does not affect the underlying Python's loop (at the C level). So just running Python through IPython does not fix our event loop problem. On Windows, for example, after importing IPython into IDLE (which most of our users will want to use), our graphics window still freezes. This leaves us with the possibility of using IPython's event loop, which it runs on top of regular Python. But if we use that, we'd either have to convince all our users to switch to IPython (which is impossible) or we have to maintain two mechanisms to hook our extension module into the event loop: one for Python and one for IPython. There are several other reasons why the alternative solutions that came up in this discussion are more attractive than IPython: 1) AFAICT, IPython is not intended to work with IDLE. 2) I didn't get the impression that the IPython developers understand why and how their event loop works very well (which made it hard to respond to their posts). I am primarily interested in understanding the problem first and then come up with a suitable mechanism for events. Without such understanding, IPython's event loop smells too much like a hack. 3) IPython adds another layer on top of Python. For IPython's purpose, that's fine. But if we're just interested in event loops, I think it is hard to argue that another layer is absolutely necessary. So rather than setting up an event loop in a layer on top of Python, I'd prefer to find a solution within the context of Python itself (be it threads, an event loop, or PyOS_InputHook). 4) Call me a sentimental fool, but I just happen to like regular Python. My apologies in advance to the IPython developers if I misunderstood how it works. --Michiel. -- Michiel de Hoon Center for Computational Biology and Bioinformatics Columbia University 1150 St Nicholas Avenue New York, NY 10032 _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
