ArgvParser

ArgvParser allows to format an argument vector in a structure easier to read and use for command line applications.

Installation

python -m pip install argvparser

Importation

import argvparser

Using

import argvparser
import sys

args = argvparser.argvparser.parse(sys.argv)

Documentation

ArgvParser.parse

Formate arguments vector to a dictionnary

:param argv: The arguments vector :type argv: list

:return: The formated arguments :rtype: dict

:raise Exception: Argument assigned to any option

:Example:

Parsing with several concatenated options

>>> argvparser.argvparser.parse(['app.py', 'ls', '-lar', '42', '--float', '3.14'])
{
    'app': 'app',
    'command': 'ls',
    'options': {
        '-l': None,
        '-a': None,
        '-r': 42,
        '--float': 3.14
    }
}

Parsing without command specified

>>> argvparser.argvparser.parse(['app.py', '--print', 'My message I want to print', '-i'])
{
    'app': 'app',
    'command': None,
    'options': {
        '--print': 'My message I want to print',
        '-i': None
    }
}

Parsing with duplicated options

>>> argvparser.argvparser.parse(['app.py', '-v', '/var/www', '-i', '-v', '/var/bin/bash'])
{
    'app': 'app',
    'command': None,
    'options': {
        '-v': [
            '/var/www',
            '/var/bin/bash'
        ],
        '-i': None
    }
}

ArgvParser.parse_multi_options

Retrieves multiple argument (like -li) and reconstruct it to a correct format

:param argv: The arguments vector :type argv: list

:return: Correctly formated arguments vector :rtype: list

:Example:

>>> argvparser.argvparser.parse_multi_options(['app.py', '-liar', '--test'])
['app.py', '-l', '-i', '-a', '-r', '--test']

ArgvParser.is_option

Check if the argument in parameter is an option or not

:param arg: The argument to control :type arg: str

:return: True if arg is an option, else false :rtype: bool

:Example:

>>> argvparser.argvparser.is_option('-t')
True

>>> argvparser.argvparser.is_option('--test')
True

>>> argvparser.argvparser.is_option('test')
False

ArgvParser.parse_type

Convert the passed argument into the appropriate type

:param arg: The argument to convert :type arg: str, None

:return: The converted argument :rtype: int, float, str, None

:note: The default type returned is a str

:Example:

>>> argvparser.argvparser.parse_type('test')
'test'

>>> argvparser.argvparser.parse_type('42')
42

>>> argvparser.argvparser.parse_type('3.14')
3.14
