argparsethis

A drop-in replacement to Python's built-in argparse, that provides the capability to argparse any arbitrary string, not just command line arguments. Is sourced from https://github.com/python/cpython/blob/3.8/Lib/argparse.py.

Installation

pip[3] install argparsethis

Usage

When creating your ArguementParser, just override the parameter input_list as a list of strings to parse. We recommend using shlex to split any raw strings into a list correctly. If input_list is not overridden, it will use standard command line arguments like normal. Also adds the exit_on_error parameter, if you want to raise an ArgumentException in the event of a parsing error or printing out the help, instead of just exiting (the default behavior).

import shlex
import argparsethis as argparse

# Argument parsing which outputs a dictionary.
def parse_args(input_str):
    #Setup the argparser and all args
    input_list = shlex.split(input_str)

    parser = argparse.ArgumentParser(input_list = input_list, exit_on_error = False)
    parser.add_argument("-q", "--quiet", help="suppress extra output", action="store_true", default=False)

    return parser.parse_args()

argv1 = parse_args("test -h")
argv2 = parse_args("test -q")

if not argv2.quiet:
    print("LOUD NOISES")
else:
    print("Please be quiet")
