Command line argument parser for pythonic code

Command Line Argument Parser for PYthonic code.

given_kwarg1 = clappy.parse("--kwarg1")

# do some stuff with given_kwarg1

given_kwarg2 = clappy.parse("--kwarg2")

Clappy allows you to parse command line arguments extremely easily and separatedly. There’s no need to manually add arguments to a parser beforehand, or reuse the parser or result in multiple scopes.

e.g. Script with clappy:

from clappy import parse

kwarg = parse("--kwarg")
parg = parse("fuga")

def set_logger():
    logger_level = parse("--log_level")
    logger.setLevel(logger_level)

set_logger()

Equivalent script without clappy:

from argparse import ArgumentParser

parser = ArgumentParser()
parser.add_argument("--kwarg")
parser.add_argument("fuga")

def set_log_level_arg(parser):
    parser.add_argument("--log_level")

set_log_level_arg(parser)

args = parser.parse_args()
kwarg, parg, logger_level = args.kwarg1, args.fuga, args.log_level

def set_level_on_logger(level):
    logger.setLevel(level)

set_level_on_logger(logger_level)

How to use

clappy is a wrapper of argparse. You can give arguments for clappy same as argparse. The reference of argparse is https://docs.python.org/ja/3/howto/argparse.html.

Just call clappy.parse(*args, **kwargs) as if argparse.ArgumentParser().add_argument(*args, **kwargs). To give some args for ArgumentParser constructor: clappy.Parser.set_args_for_parser_getter(*args, **kwargs) If you want to generate help automatically, call clappy.create_help(). It must be done after all arguments got parsed.
