Hey Omar,

This looks like a great start, thanks!  As Thomas mentions, that's the
easiest way to activate debugging for tab completion.  What I
recommend is that you study the qt frontend for behavior, since
effectively what you are doing is implementing the same basic
architecture.  The qt console converts a tab key event into a
completion call to the kernel, in your case you'll need to do that via
readline by registering a completer.

I've put up the original zmq example as its own repo here:


so that you can easily see how all that works.  This is the old code
you may have already seen, but having it available in an
easy-to-reference permanent location is probably a good idea.

Let us know if any of this doesn't make sense...
