Is it possible to use vi motions in the default internal shell?

[cohml]

The native Python REPL uses readline, meaning configurations set in ~/.inputrc are respected. One such configuration is set editing-mode vi, which enables some basic vi motions.

pudb's "internal shell" seems exactly like the native Python REPL, so I had suspected it would use readline as well. However, I am unable to use vi motions in the internal shell, despite set editing-mode vi being enumerated in my ~/.inputrc.

So how, if at all, can I use vi motions in pudb's internal shell? I don't see that this is addressed in the README/documentation.

Possibly related to ##547.

That text entry box uses https://github.com/rr-/urwid_readline, so probably the most useful course of action would be to extend that to understand vi keys. It's not a priority for me, but if some were to put together PRs to make it happen, I likely wouldn't stand in the way.
