C-Like main method support
Project description
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;
main()
. -> No command line arguments.main(argv)
(ormain(args)
) -> Getsys.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.
