listen

Simple but powerful signal handling to process OS signals in python

##Example Usage:

import listen
import subprocess

Instanciate SignalHandler

sig_hand = listen.SignalHandler()

Start external process

external_process = subprocess.Popen(['sh', '-c', 'sleep 30'])

Register some signal handlers to kill external process on SIGINT (ctrl-c)

kill_event = sig_hand.reg_on_status(external_process.kill)

Wait for external process

external_process.wait()

Press ctrl-c to send SIGINT or alternatively use the following to unregister the event

sig_hand.del_status_event(kill_event)

For a more detailed example including interaction with bash please see the tests/example.py and tests/external_process.bash
