duckargs 0.1.0

duckargs

The purpose of this package is to save some typing whenever you want to quickly create a python program that accepts command line arguments. Just run duckargs with the arguments that you want your program to accept, with example values for options, and duckargs will generate the python code for a program that uses argparse to handle those arguments.

Example

Run duckargs from the command line via python -m duckargs, followed by whatever arguments/options/flags you want your program to accept, and duckargs will print the corresponding python code.

$ python -m duckargs -i --intval 4 -f 3.3 -F --file file_that_exists -a -b -c positional_arg

import argparse

def main():
    parser = argparse.ArgumentParser(description='',
                                     formatter_class=argparse.ArgumentDefaultsHelpFormatter)

    parser.add_argument('-i', '--intval', default=4, type=int, help='an int value')
    parser.add_argument('-f', default=3.3, type=float, help='a float value')
    parser.add_argument('-F', '--file', default='file_that_exists', type=argparse.FileType('w'), help='a filename')
    parser.add_argument('-a', action='store_true')
    parser.add_argument('-b', action='store_true')
    parser.add_argument('-c', default='positional_arg', help='a string')
    args = parser.parse_args()
