Emacs下用于Windows的ipython挂壳

Question

Hi I recently downloaded ipython 0.12.1 – April 2012 and got it to work under Windows' terminal. ie I open a command prompt and type ipython and then the ipython prompt appears.

All good and dandy until I needed to use it in emacs. So before even trying to use the pyton-mode.el or ipython.el (which at the moment freeze my emacs ), I tried to do a Mx shell or Mx eshell and type ipython -i.

This is the trace I get before a complete hang of the shell:

ipython -i

Defaulting color scheme to 'NoColor'

So why does it hang in the emacs shell and work in a regular command prompt. Do I need to change my default emacs shell? I also tried this on two different machines. Am I missing something?

Well apparently the only way to do this under Windows is to create a batch file, even though in the 0.12 distribution there exists an executable (ipython.exe). My script reads as follows:

[ipython.bat] @python.exe -i C:\\devel\\Python\\2.7-bin\\Scripts\\ipython-script.py --pylab %*

For the users of matplotlib and numpy under Windows, the pylab option still doesn't work correctly as it will freeze your figure windows. To get that working, I had to revert to ipython 0.10 and use the -wthread option rather than -pylab in the ipython.bat script. This actually produces a nice interactive-figure environment
