zsv.ticker 1.1.0

Enabling flexible and idiomatic regular execution of tasks.

zsv.ticker enables flexible and idiomatic regular execution of tasks:

from zsv.ticker import Ticker

ticker = Ticker()
ticker.start(5)

while ticker.tick():
    execute_task()

Ticker aims to be more idiomatic and easy to use than a time calculation and sleep call, and further enables the instantaneous termination of a waiting task:

import signal
from time import sleep
from zsv.ticker import Ticker

ticker = Ticker()
ticker.start(5)

def abort(signum, frame):
    ticker.stop()

signal.signal(signal.SIGINT, abort)

while ticker.tick():
    print("tick")
    sleep(2)
    print("tock")

The above script wraps a stop call in a signal handler registered to SIGINT: hitting Ctrl+C after the script prints “tick” but before it prints “tock” will yield a final “tock” before it terminates.
