lazy-main

Generalized framework for main loop function.

Installation

pip install lazy-main

How to Use

from lazy_main import LazyMain

def main(*args, **kwargs):
    print("Hello World!")

def error_handler(exception):
    print("An error occurred!", exception)

if __name__ == "__main__":
    LazyMain(
        main=main,
        error_handler=error_handler, # This is optional.
        sleep_min=3,
        sleep_max=5,
        print_logs=True,
        loop_count=-1, # -1 Means it will loop infinitely.
    ).run()

You can also pass arguments to the main function.

from lazy_main import LazyMain

def main(*args, **kwargs):
    print(kwargs["hello"]) # World!

if __name__ == "__main__":
    LazyMain(
        main=main,
    ).run(
        hello="World!",
    )

Returning True will print the total elapsed time.

from lazy_main import LazyMain

def main():
    return True

if __name__ == "__main__":
    LazyMain(
        main=main,
    ).run() # Done in 0.10s.

Returning SIGTERM will terminate the loop.

from lazy_main import LazyMain
import signal

def main():
    return signal.SIGTERM

if __name__ == "__main__":
    LazyMain(
        main=main,
    ).run()

    print("I'm free!")
