mainmethod 0.1.0

C-Like main method support

mainmethod.py

Provides C-like main method support.

Sample usage:

# file: script.py
from mainmethod import mainmethod

@mainmethod
def main():
    print('hello, world!')

Running the script defined above will execute the method main.

$ python script.py
hello, world

No more need for

if __name__ == '__main__':
    main()

The decorator inspects the method marked as main and supports these signatures;

1. main(). -> No command line arguments.
2. main(argv) (or main(args)) -> Get sys.argv passed to the main method call.

from mainmethod import mainmethod

@mainmethod
def main(argv):
    message = 'hello, world'

    if '--loud' in argv:
        message = message.upper()

    print(message)

The decorator also automatically gathers the return value from the main method and uses it as the return status code.
