non-interactive ipython for script


I  need to be able to run certain ipython magic commands using the plain vanilla python interpreter.

In other words, I have an ipython script that I can certainly invoke using ipython on the command line, but I need to  run the script using python on the command line.

I know it has  something to do with importing IPython, but I can't do the IPython.Shell.start().mainloop() part since I need non-interactive running.

I hope that made some sense.

Any help appreciated.

ipython in emacs

Hi,
 
Even though I could not make ipython work with emacs 23.2 in window xp. It is very easy to make it work in Linux. However, the most important feature of ipython is missing inside emacs. That is retreiving the previouse command from command history.
 
In ipython running from normal shell, press up and down arrow key will bring back the previouse or next command. If you type some character of previous command and press the up and down arrow key, ipython will automatic search backward for the command starting with the character. If it is not the command you want, you can press the up arrow key again. However, inside emacs, the up and down arrow keys will more the cursor up and down. It cannot retrieve the previous command. If you type the character of the previouse command, up arrow key will not search the command. The tab key will not complete the command inside emacs.
 
Does anyone know how to fix this?
 
Thanks
 
Frank

C-up instead of just up.  Since Emacs implements its own cursor
functionality, it overrides readline.  So the keystrokes aren't quite
the same, but you can get pretty much the same functionality (at some
cost in muscle memory).

cheers,

No need to strain your poor muscles' limited mental ressources :) 

I think the following should do (added somehwere at the front of your .emacs),
either without prefix matching:

    (define-key comint-mode-map (kbd "<up>")
       'comint-previous-input)
    (define-key comint-mode-map (kbd "<down>")
       'comint-next-input)

or, I think handier, with:

    (define-key comint-mode-map (kbd "<up>") ; (I bind that to M-p)
      'comint-previous-matching-input-from-input)

    (define-key comint-mode-map (kbd "<next>")
      'comint-next-matching-input-from-input)

cheers,

'as

Re: Ipython inside Crunchy

Hi all,

here's another ipython-related video from the popular ShowMeDo series!
 I've played with Crunchy briefly in the past and it looked really
cool; I haven't had time to use the new one with ipython but I'd love
to test it soon.

Thanks to Ian for the tip and André for the work (as well as Crunchy!).

Cheers,

f

problem of "!start ." with -q4thread

ipython 0.8.2 and python2.5.1 on windows xp sp2
If I start ipython without -q4thread, cd some bookmarked directory.
and "!start ." will pop up a explorer of current directory without
blocking.
if i stat ipython with -q4thread, then  i can run some pyqt4 script
without blocking. but "!start ." will block ipython until i press
"ctrl + break"..., it kills ipython shell, and show the explorer...

Do you have the same problem with -gthread or -wthread?

Re: problem of "!start ." with -q4thread

o, didn't install pyqtk and wxpython. i am blind to pyqtk, so only
download wxpython 2.8.7.1 (unicode  version for python2.5)
now, -wthread blocking "!start ." same as "-q4thread"...

Re: problem of "!start ." with -q4thread

oops, the blocking will disappear after about one minute with -wthread
or -q4thread.
