FYI: Since we import from the notebookapp, we will have to change eventually, but we don't now since that construction is backwards compatible.

Hey everyone,

we've just landed PR #3450: https://github.com/ipython/ipython/pull/3450

To quote Fernando:

The basic idea is to move all the code we had in frontend and put it at the top, as recently discussed, and then to create a shim module capable of forwarding all `from IPython.frontend... import...` to their new locations.

Here's the rundown of name changes: Old name -> New name IPython.frontend.* -> IPython.* IPython.frontend.html.notebook -> IPython.html

With only one exception, you do not have to make any immediate changes to your code in order for it to continue working, but will see deprecation warnings

The one exception is described by Min in a comment on the PR which I am inlining here:

The shim is a tiny bit more complicated now, since it's not just moving IPython.frontend.* to IPython.* anymore, as IPython.frontend.html.notebook became just IPython.html. A result of the extra shim is that there is one old import that doesn't work:

from IPython.frontend.html import notebook

but

from IPython.frontend.html.notebook[.submod] import whatever

works just fine.

One issue that we ran into that you should be sure to remove the frontend/ directory, and clean up all .pyc files that may be lying around. This command should do the trick:

rm -fr IPython/frontend; find -name *.pyc -exec rm {} ;
