`ipython` tab autocomplete does not work on imported module

simply adds a tab.

Someone else in StackOverflow posted this link: http://www.vankouteren.eu/blog/2009/06/getting-ipython-readline-and-auto-completion-to-work-on-mac-os-x/

Its basicly easy_install readline than discover where the readline egg got installed and edit the ipython bin script to use this readline:

1. Install the "official" readline: easy_install readline
2. Discover where it is. Look at /Library/Python/site-packages/readline-*.egg or in your Virtualenv counterpart
3. Discover where ipython bin is: which ipython
4. Add ONE LINE to this file, adding the readline egg path right after import sys line.

My virtualenved ipython bin script got working as follow:

#!/Users/alanjds/src/git/cervejeiras/venv/cervejeiras-lfs/bin/python
# EASY-INSTALL-ENTRY-SCRIPT: 'ipython==0.13.1','console_scripts','ipython'
__requires__ = 'ipython==0.13.1'
import sys

### ONLY LINE ADDED:
sys.path.insert(0, '/Users/alanjds/src/git/cervejeiras/venv/cervejeiras-lfs/lib/python2.6/site-packages/readline-6.2.4.1-py2.6-macosx-10.6-fat.egg')

from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.exit(
        load_entry_point('ipython==0.13.1', 'console_scripts', 'ipython')()
    )
