Allow repl launched from code to be handled from within notebook?

[riffraff]

The use case is the following: I have a long data massaging loop like

entries.each do 
  begin
    ... a lot of stuff that can go wrong
  rescue => e
   binding.pry
  end

if an error occur, I end up inside a pry session and I can properly inspect the data, error and eventually re-run the computation.

If I do this from within a notebook though the new pry session is launched in the underlying terminal, somewhat conflicting with the notebook logs.

It would be awesome to have the ability to launch a sub-repl from the notebook and interact with it.
Would this be possible, or it maybe already is, or does what I'm saying not even make sense?

Anyway, thanks for your work on iRuby, it's awesome.

If I understand correctly, you basically want a console inside your browser that can let you examine the contents of your objects right?

yep

Yes, this should be fixed. However the current support for pry is basically a hack if you take a look at the backend. Unfortunately the internal pry code is not really transparent to me. It would be best if someone of the pry guys could take a look into that and tell us how to interface iruby properly with pry. Maybe you could ask over there?
