Default subcommand if no one specified

[everbird]

I would like go write some script without subcommand like this:

def run(args):
    print args.foo

if __name__ == '__main__':
    parser = argparse.ArgumentParser()
    parser.add_argument('-f', '--foo', help='bar', default='baz')
    args = parser.parse_args()
    run(args)

So that I can just simply run ./script.py.

But I found it's hard to achieve this using komandr. Because self.parser.add_subparsers() in the constructor make the subcommand a must. So I did a little hack to make the script work like this:

@komandr.arg('foo', '-f', '--foo', help='baz')
@komandr.command
def run(foo='bar'):
    print foo

if __name__ == __main__:
    komandr.main(default_subcommand='run')

The specified default subcommand would be called unless the first argument was --help or --version or other options which registed to the parser at first.

komandr is cool and I hope this a little hack would help to make it better.

Cheers
