import tab-complete fail with ipython 2.0 shell

[GhislainHivon]

In the shell, when trying to tab-complete a module name for import, the propose completion is not modules names.

with ipython 2.0

>>> import co<tab>
coerce(     compile(    complex(    continue    copyright(

That the same list as when tab-complete without anything

instead of what ipython 1.1 give

>>> import co<tab>
code                codeop              commands            configparser        contextlib          copy_reg
code_erreur         collections         compileall          constantes          cookielib           copyreg
codecs              colorsys            compiler            constantes_vivaldi  copy                coverage

I'm on fedora 17, with python 2.7 in a virtualenv

I am also seeing this. I'm using OSX and Python 2.7 provided by brew. Works fine with IPython 1.2.1 and earlier.

A user reported the same bug under Mageia with Python2.7 and Python3.3

So far I'm unable to replicate this (Debian, Python 3.3 and 2.7), and unsure what could be causing it - I don't think that code has had any major changes since 1.x.

@GhislainHivon @drkjam do you have PYTHONSTARTUP set?

[mario-grgic]

Ok, some more info here. I have PYTHONSTARTUP variable defined.

echo $PYTHONSTARTUP
/Users/mariogrgic/.pythonrc
$
$ cat .pythonrc
import rlcompleter
import readline

readline.parse_and_bind("tab: complete")
del rlcompleter
del readline

If I now unset PYTHONSTARTUP

$ unset PYTHONSTARTUP

and launch IPython, import completions now work. So it does have something to do with PYTHONSTARTUP variable or what the startup script is doing.

[takluyver]

IPython now runs PYTHONSTARTUP, and is less aggressive about using its own completer. So when you configure a more basic completer in PYTHONSTARTUP, IPython ends up using that instead of its own completer.

[mario-grgic]

Ok, that explains it. I'm not sure if this is not working for the same reason for other people experiencing this problem.

[GhislainHivon]

Same thing, PYTHONSTARTUP with readline.parse_and_bind("tab: complete") in it.

I found a easy way to test if in ipython
http://stackoverflow.com/a/17826459/611741

try:
     cfg = get_ipython().config
     # in pyton
 except :
     pass 

[takluyver]

The name get_ipython should exist if it's run from IPython.
