import gone

## as a decorator:

@gone.args
def greet():
    return "Hello World"

greet(1, 2, key=3)  # Result: Hello, world!

@gone.result
def add(a, b):
    return a + b

print(add(1, 2))  # Output: None


@gone.inout
def display_message():
    print("This will print, but inputs and outputs are ignored.")
    return "ignored"

display_message("ignored input")  # Output: This will print, but inputs and outputs are ignored; Returns: None


## or as a function:

import os, signal

def main():
    def sig_handler():
        print("Runs without the default 'signal, frame' arguments!")
        return "ignored"

    # listen to signal:
    signal.signal(signal.SIGFPE, gone.inout(sig_handler))
    # just `sigint_handler` would crash because it's getting unexpected args

    # send signal:
    os.kill(os.getpid(), signal.SIGFPE)
