Installation

python -m pip install --upgrade jarguments

Usage

There are three steps to using the jarguments library:

1. Import the jarguments library.

   from jarguments import create, parse
   

2. Provide your arguments with jarguments' classes.

   # argument parser
   args = parse.JParser(
   
     # boolean argument
     create.JBool('show-text', helpstring='determines whether "text" is shown'),
   
     # integer argument
     create.JInt('number', default=1),
   
     # string argument
     create.JStr('text'),
   )
   

3. Use the outputs; they're parsed automatically!

   if args.show_text:
     for _ in range(args.number):
       print(args.text)
   

Now it works just like any other command line application.

$ python example.py --show-text --text "hello" "world"
["hello", "world"]

• Arguments without a default value are required. If you don't provide them, the script will raise an error:

  $ python example.py --show-text
  error: the following arguments are required: --text
  

• The --help/-h flag displays help messages:

  $ python example.py -h
  usage: example.py [-h] [--show-text [SHOW_TEXT]] [--number NUMBER] --text [TEXT ...]
  
  options:
    -h, --help            show this help message and exit
    --show-text [SHOW_TEXT]
                          determines whether "text" is shown
    --number NUMBER
    --text [TEXT ...]
