[Message part 1 (text/plain, inline)]

Hi all!

I'm having trouble getting IPython to work with emacs 24.4 under windows
7 (on my linux laptop, it works out-of-the-box). When using ipython and
running
'run-python' I see the IPython interpreter loaded. I get no 'in' prompt,
but when writeing for instance '2+4' and hitting enter, I get 'Out [1]:
6'. When typing 'print("foo")', hitting enter produces nothing. But,
after running 'quit()' I see 'In [5]: foo'. There seems to be something
wrong in how emacs is handling the IPython output. How can I fix this?
Where can I start to look? Which file is responsible for the interaction
between the ipython output and emacs buffer?

I'm at a loss here and would apriceate any help. Thank you in advance! :)

Best regards,

Aron

Hi Aron,

Have you tried following this comment from python.el's header:

;; Running IPython on Windows needs more tweaking.  The way you should
;; set `python-shell-interpreter' and `python-shell-interpreter-args'
;; is as follows (of course you need to modify the paths according to
;; your system):

;; (setq python-shell-interpreter "C:\\Python27\\python.exe"
;;       python-shell-interpreter-args
;;       "-i C:\\Python27\\Scripts\\ipython-script.py")

If not, please give it a go and let me know if it worked.



Cheers,
Fabián.
