workaround for IPython + Emacs + WinXP
Windows XP SP2
these are the steps I needed to get ipython working under emacs
First, to get ipython.el to work you need to edit the ipython.bat file and add a -i flag: i.e.
next, something is broken with the way readline's _outputfile interacts with ipython under emacs/winXP.
I can get IPython working in emacs by modifying line 122 in genutils.py:
if sys.platform == 'win32' and readline.
EM_PARENT_PROCESS is a variable inserted into the environment when running processes under emacs.
This tells ipython not to use readline's _outputfile when running under emacs on windows.
Finally, tab complete is broken under python 2.6 and using my version of ipython.el (may be fixed in the latest version)
In ipython.el, change the value of ipython-
"The string send to ipython to query for all possible completions")
This uses 2.6 print() function conventions, and should work with python 2.5 as well.
It also looks as if the history files generated by the emacs IPython and the command prompt ipython are incompatible; sometimes the emacs IPython will crash with a strange readline error. I've been deleting the _ipython/history file, which is somewhat annoying (but IPython can log sessions easily anyway).
