This is not a problem to me since C-D (kill python) and F12 (or using
the original shortcut, to start python again) are easy enough to me.
To clear some confusion (what works and what does not), here is my test results:
1. python (any version) + python-mode.el (any official version)
without ipython: no problem.
2. ipython + updated python-mode.el + ipython.el from SciPY.org has
this buffer-switching problem.
3. (NOW) ipython + Probhu's new python-mode.el + ipython.el does not
have this problem.
I am excited that I can now enjoy the power of ipython as well as
emacs. With the attached emacs configuration, my way of working with
python script is:
1. emacs myscript.py, maxmize emacs window, C-x 3 ( split window )
2. F12 (start python/ipython )
3. start working:
-- F9 (step through statement)
-- F10 (submit selected region)
-- F11 (submit the whole script)
-- If I need to test run some command, I will use F12 to switch buffer
-- In case python needs to be restarted, C-D and F12 again.
-- all features of ipython is still there, in the ipython buffer
Here is the emacs code: (with Prabhu's fix)
; This file provide some convenient ways to debug your program
; More specifically, in python mode of emacs, you can use
; F9 to run a statement and forward to the next
; F10 to run selected text
; F11 to run the whole buffer.
; F12 to switch between src and shell buffer.
; start python-shell if necessary

(setq py-shell-switch-buffers-on-execute nil)
(defun goto-python-shell ()

(setq current-python-script-buffer (current-buffer))
(defun goto-python-source ()
