Better handling of KeyboardInterrupt in cmd.Cmd command line interpreter

Question

While using python\'s cmd.Cmd to create a custom CLI, how do I tell the handler to abort the current line and give me a new prompt?

Here is a minimal example:

Answer 1

Just add this inside the class Console(cmd.Cmd):

    def cmdloop(self):
        try:
            cmd.Cmd.cmdloop(self)
        except KeyboardInterrupt as e:
            self.cmdloop()

Forget all the other stuff. This works. It doesn't make loops inside of loops. As it catches KeyboardInterrupt it calls do_EOF but only will execute the first line; since your first line in do_EOF is return do_exit this is fine.
do_exit calls postloop.
However, again, it only executes the first line after cmd.Cmd.postloop(self). In my program this is print "\n". Strangely, if you SPAM ctrl+C you will eventually see it print the 2nd line usually only printed on ACTUAL exit (ctrl+Z then enter, or typing in exit).
