Thanks. Glad you like it.

I couldn't do it. Tried a lot, never got it to work. But if someone can figure
it out, I'll be glad to fix it for a future release. That's how I use my
normal shell and would love to set the same thing in ipython, but I wasn't
able to fix this.

Actually, @edit is bound to call $EDITOR. I am an XEmacs user myself, the only
thing I know how to do with vi is 'C-Z; killall vi' when I accidentally open
it :) You can set your editor environment variable to anything you want. I
personally use jed for quick edits, so I set $EDITOR to that, and I use
Xemacs for heavy-duty work. Now, with Alex Schmolck's help who patched the
Xemacs python mode, it _is_ possible to use ipython inside emacs as your
python shell. I just uploaded the new python-mode.el file to the download
directory for ipython, so you can grab it from there. I also put the
following in my emacs config file, as per Alex's instructions:
(defun my-activate-ansi-colors ()
(add-hook 'py-shell-hook 'my-activate-ansi-colors)
;; Regular expression that describes tracebacks for IPython in context and
;; verbose mode.
;; this works for @xmode verbose or context
"^\\(.+?\\) in [^\00]+?\n--> \\([0-9]+\\) +")))
(setq py-shell-input-prompt-1-regexp "^In \\[[0-9]+\\]: "
py-shell-input-prompt-2-regexp "^ [.][.][.]+: " )
;; Set IPython to be the python command and give it arguments
(setq py-python-command "ipython")
((eq frame-background-mode 'dark)
((eq frame-background-mode 'light)
(t ; default (backg-mode isn't always set by XEmacs)
Let me know if this works ok for you.
