pip install ricekeyAfter you have installed the package, check that its working by running the module directly. This will demonstrate an example keypress kill event.
cd /path/to/ricekey-package/src/ricekey/
python ricekey.pyBelow is an example of how you can use ricekey to stop your main thread if you need to:
from ricekey import kbcontrol
from riceprint import ConsolePrinter, pprint, tprint, progressbar
cp = ConsolePrinter()
import threading
import time
# Start the keypress monitoring thread
thread = threading.Thread(target=kbcontrol, args=())
thread.start()
# While the thread is alive, do something.
i = 0
while thread.isAlive():
c = cp.palette.colors[i % 16]
progressbar(i%100, 100, color=c, char='\u2587', lend='|', rend='|')
time.sleep(0.01)
i+=1
pprint('Done! I hope you use this package!', 'dm')
