Enabling auto-completion in a notebook -- beginner question

[stereophonics]

I've just installed EIN and it looks amazing. However, I'm unable to get auto-completion working in a notebook.

I have the following lines in my ~/.emacs (from the documentation): (require 'ein) (setq ein:use-auto-complete t) (setq ein:use-smartrep t)

When I open the notebook, is bound to py-indent-line in python-mode.el and C-c is bound to py-indent-region.

Running M-x ein:completer-complete (or C-c C-i) generates the following error (in Warnings): Error (websocket): in callback `on-message': Symbol's function definition is void: string-prefix-p

I'm running emacs 23.1.1 on a 64-bit Ubuntu box. I am running ipython 1.0.dev and python 2.7.3. The mode-bar for the notebook says (ein:ml AC)

I've spent a bunch of time web searching for answers, but haven't been able to find anything. I'm probably missing something easy. How can I get completion working? And how can I bind it to TAB? Can someone help out?

Thanks in advance!

Also, I enabled the debug mode (following https://github.com/tkf/emacs-ipython-notebook/issues/42) and here's what the Backtrace buffer shows when I type C-c C-i in the notebook after the text "from mat" (looking for matplotlib), I get the following error:

I think Emacs 23.1.1 is too old for EIN. I may be able to fix it by adding some backward compatible functions, but as I don't have 23.1 in my machine, chance is very low. Why not upgrade to 24.x? You will have some other goodies in the latest version of Emacs.

Re: TAB. I think you may not need this when you have AC enabled. Completion happens really "automatically". Completion just pops up when you type something.

(Forgot to hit send on Monday)

Ok, I will upgrade. Thanks for the quick response. I'll let you know how it goes, but installing emacs is easier said than done on a machine on which one is not root

No chance the issue is with ipython-1.0.dev?

[tkf]

You have Debugger entered--Lisp error: (void-function string-prefix-p) which means that your Emacs don't have this function but EIN needs it.

[stereophonics]

I defined that function in my .emacs and EIN completion is working now. Thanks!

[tkf]

Congrats. That's actually good to know that EIN works in Emacs 23.1. I couldn't build it so I couldn't test it.

[tkf]

Let me close this as it seems the issue is resolved.

[mjanardhan]

Hi, I am trying to setup EIN with emacs 23.1, could you share your experiences?
