autocompletion in "from package import <tab>"

[mqlaql]

This is a small feature request.

In the Ipython notebook when I type sk <tab>, Ipython autocompletes sklearn. That is very useful. However, when I type from sklearn import <tab>, it shows an empty pop up with the text <empty docstring> .

In my opinion, it would be really useful to get the list of objects associated to the referred package. In this example, that would be sklearn.__check_build, sklearn._build_utils, sklearn._hmmc, etc.

terminal IPython already does this, so it shouldn't take much to fix the notebook to make a proper completion request.

Ok, got a way to get around that, but it is not easy if we don't want to add python assumption in it.

The issue is that "tab" has been weaponize and that we need to "guess" wether one want to complete or tooltip.
Right now if the cursor is preceded by space or '(' we invoke tooltip.

foo( param1, <tab> will get help on foo(

Otherwise, completer is invoked.

I can special case import <tab> to complete, but it is python specific.
You could also in custom.js set IPython.config.tooltip_on_tab = false and use Shit-Tab to trigger tooltip (this should also work if you select text and press shift tab, it will trigger help on selection).

In any case, I'm not sure there is a really perfect way to deal with that. But we might have to in any case separate complete from tooltip as language like julia will more likely need more complex heuristic in the kernel where we cannot decide on frontend what to do.

@Carreau what is the status of this?
