[IPython-dev] embedding ipython, namespace question

[Darren Dale]

I passed None because
http://ipython.org/ipython-doc/stable/api/generated/IPython.terminal.embed.html?highlight=embed#IPython.terminal.embed.InteractiveShellEmbed
states: "If given as None, they are automatically taken from the scope
where the shell was called, so that program variables become visible." That
is precisely what I want, but can't figure out how to do it with the Qt
console.

I don't want to inject variables to an isolated namespace, I want the
console to share the application's namespace.
