code

from miniconfig_argparse import get_configurator


config = get_configurator()
config.include("yourmodule")
config.include("yourmodule.extra")

args = config.make_args()
# using args

in yourmodule, using config like a below.

def includeme(config):
    parser = config.parser

    parser.add_argument(
        '-v', '--verbose', action='count', default=0,
        help="(default option: increment logging level(default is WARNING))"
    )
    parser.add_argument(
        '-q', '--quiet', action='count', default=0,
        help="(default option: decrement logging level(default is WARNING))"
    )

    def setup_closure(args):
        logging_level = logging.WARN + 10 * args.quiet - 10 * args.verbose
        logging.basicConfig(level=logging_level)
        return args

    parser.add_callback(setup_closure)

default directives

• make_parser
• replace_parser
• call_function_as_command

make_parser(fn) + call_function_as_command

Using make_parser() and call_function_as_command() combinations are useful, sometimes.

• make_parser(fn) – creating parser from a function definition.
• call_function_as_command – call function using parsed argument object.

Such as below.

def greeting(message, is_surprised=False, name="foo"):
    """ greeting message

    :param message: message of greeting
    :param is_surprised: surprised or not (default=False)
    :param name: name of actor
    """
    suffix = "!" if is_surprised else ""
    print("{name}: {message}{suffix}".format(name=name, message=message, suffix=suffix))


def includeme(config):
    parser = config.make_parser(greeting)
    config.replace_parser(parser)


if __name__ == "__main__":
    from miniconfig_argparse import get_configurator
    config = get_configurator()
    config.include(includeme)

    args = config.make_args()
    config.call_function_as_command(greeting, args)
