[IPython-user] ipython in emacs <tab> filename completion (again)

[Arthur Woll]

OK -- so it turns out I had to STFW, but More Carefully than I had done 
before. Is STFWMC in fashion?

Solution 
1(http://www.nabble.com/TAB-Completion-for-emacs-with-python-2.6-td22025019.html) 
:

Edit ipython.el rev 2927 (which is in the ipython distro at 
ipython-0.10/docs/emacs/) line 314 to read

"print(';'.join(__IP.Completer.all_completions('%s')))\n"

and NOT

"print ';'.join(__IP.Completer.all_completions('%s')) #PYTHON-MODE 
SILENT\n"

as distributed. (Is there a context where the later is correct? If not,  
can A.S. move to Rev 2928? )

Solution 2 (Really, a variant of solution 1, from 
http://www.emacswiki.org/emacs/PythonMode#toc14)

Add:

(setq ipython-completion-command-string 
"print(';'.join(__IP.Completer.all_completions('%s')))\n")

to your .emacs file (or alternatively ~/Library/Preferences/Aquamacs\ 
Emacs/Preferences.el)

Summary:

The minimum mods to my Aquamacs dists  (1.9 based on GNU 22.3.1 and 
2.0preview based on GNU 23.1.1)  that get ipython TAB completion working 
(and hopefully debugging) are:

1) Stick python-mode.el (5.1.0) and ipython.el (modified as above in 
Solution 1, or corrected as in Solution 2) into my load path (I use the 
Aquamacs default location ~/Library/Preferences/Aquamacs\ Emacs/)

2) put a line:
(require 'ipython)
into either ~/.emacs OR (the Mac-conforming Aquamacs location 
~/Library/Preferences/Aquamacs\ Emacs/Preferences.el)

Note:  see iptyhon.el for additional nice customizations to access history

Suggestion:

It might be nice (for newcomers like me) to have this info more explicit 
on the iPython site, e.g. here:

http://ipython.scipy.org/moin/Cookbook/IPythonEmacs23

and/or here:

http://ipython.scipy.org/doc/rel-0.10/html/config/initial_config.html?highlight=emacs#x-emacs-configuration

With the mods above, you can start an ipython shell with M-x py-shell. 
(Option - x py-shell for me).
