Simple but powerful signal handling to process OS signals in python
Project description
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
