resettabletimer

Wrapper for threading.Timer to provide a resettable Timer implementation. Also provides fake timer for testing.

Usage

ResettableTimer

from resettabletimer import ResettableTimer

delay = 5 # seconds
function = print

# Create resettable timer
t = ResettableTimer(delay, function, ["Hello"], {"end":" timer!\n"})

# Starting and canceling work similarly than with threading.Timer
t.start()

# Wait 1-5 seconds

# Reset the timer
t.reset()

# Hello should be printed after five seconds

FakeTimer

from resettabletimer import FakeTimer

t = FakeTimer(2, print, ["Hello"], {"end":" timer!\n"})

# Starting and canceling work similarly than with threading.Timer
t.start()

# Wait >2 seconds
# Nothing happens

# Time passage is controlled with pass_time
t.pass_time(2)

# Hello should be printed
