I'm using emacs24.0.92 with IPython 12. I took ipython.el file from IPython repository and also tried this patch however auto-completion still does not work for me. Can someone give any hint about it ?
That's an old question but since I was looking for it:
1- python-mode.el
A quick search lead me to this working solution: http://www.emacswiki.org/emacs/PythonProgrammingInEmacs#toc5
2- jedi
You still can use the completion given by jedi.el:
http://jedi.jedidjah.ch/en/latest/
http://wikemacs.org/index.php/Python#Jedi
http://aliquote.org/memos/2013/02/11/emacs-auto-completion-for-python
Install with packages.el and call M-x jedi:setup. Now the completion fires at the third character. We still can not inspect an object with TAB like in a terminal, but with the 1st solution we can.
edit: false, it's just a matter of configuration: http://tkf.github.io/emacs-jedi/released/#configuration (use jedi:complete-on-dot to complete as soon as we enter a dot).
