Hugo,
Unfortunately, the APIs you are using have been completely refactored
and IPython has a very different design in these areas. I suggest
looking at the app code here as a starting point:
https://github.com/ipython/ipython/blob/master/IPython/frontend/terminal/ipapp.py
But you are going to have to spend some time becoming familiar with
the IPython internals...
Cheers,
Brian
