argunparse

Reversed argparse: generate string of command-line args from Python objects.

The argunparse is intended to perform an approximate reverse of what argparse does. In short: generating string (or a list of strings) of command-line arguments from a dict and/or a list.

How to use

Simple example of how argunparse works:

import argunparse

options = {
    'v': True,
    'long-flag': True,
    'ignored': False,
    'also-ignored': None,
    'o': 'out_file.txt',
    'log': 'log_file.txt'
    }
args = {
    'in_file.txt'
    }

unparser = argunparse.ArgumentUnparser()
print(unparser.unparse(*args, **options))
# -v --long-flag -o=out_file.txt --log=log_file.txt in_file.txt

print(unparser.unparse_to_list(*args, **options))
# ['-v', '--long-flag', '-o=out_file.txt', '--log=log_file.txt', 'in_file.txt']

Special option values are:

• True -- option will be treated as a flag;
• False and None -- option will be ignored.

All other values will be converted to strings using str().
