clappy 0.1.7

Command line argument parser for pythonic code

Command Line Argument Parser for PYthonic code.

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

You can get each given command line argument easily. You don’t have to bother about using parser anymore.

e.g. Script with clappy:

import clappy as cl

kwarg = cl.parse("--kwarg")
posi_args = cl.parse("fuga")

def set_logger():
    logger.setLevel(cl.parse("--log_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, posi_args, logger_level = args.kwarg1, args.fuga, args.log_level

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

set_level_on_logger(logger_level)

When you accept arguments from command-line in multiple scopes, you must give the parser and result to another scope. Clappy will solve it!

Install

pip install clappy

How to use

clappy is a wrapper of argparse. You can give arguments for clappy same as argparse. Reference of argparse is here.

Just call clappy.parse(*args, **kwargs) as if argparse.ArgumentParser().add_argument(*args, **kwargs). Both methods accept same args.

If you want to generate help automatically, call clappy.create_help(). It must be done after all arguments got parsed.

To give some args for ArgumentParser constructor: initialize parser with clappy.initialize_parser(*args, **kwargs).
