From be4cd8edd024b293c54daf09d3a2fd3e04155d53 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Thu, 20 Sep 2012 13:16:32 +0200 Subject: [PATCH] test_key: add small helper for client-side key-input We sometimes need to test what keys a client receives when specific keys are pressed. This small helper simply runs in a terminal and receives raw keyboard input and prints it to stdout with debugging information. This can definitely be improved with the help of the TSM state-machine to print more useful information and directly parse the input. However, this is better than nothing.
