Argum

A package for getting command line arguments in a simple way.

Install

Install with

npm install --save argum

How to use

First require argum

var argum = require('argum');

then to get an argument's value use this

var argumentValue = argum.get(<prefix>, <required>, <defaultValue>)

where 'prefix' is the prefix with which the argument starts (note that the prefix and actual value must be separated by equals sign '='). 'required' is whether the argument is required or not, if it is required and the argument is not passed in argum will throw an error. 'defaultValue' is the default value in case of the argument not being required.

Example

Given a command line call like this one

node index.js --name=Petar --surname=Vasilev

and the following code

var argum = require('argum');  

var config = {
    name: argum.get('--name', true, false),
    surname: argum.get('--surname', true, false),
    race: argum.get('--race', false, 'human')
}

config.name will have a value of 'Petar'. config.surname will have a value of 'Vasilev' and config.race will have a value of 'human'.

There is now an 'object' method as well which can be used to get values from an object literal in much the same way the 'get' method is used to get command line arguments. For example this:

var argum = require('argum');
var options = {name: 'Petar', surname: 'Vasilev'};

var config = {
    name: argum.object(options, 'name', true, false),
    surname: argum.object(options, 'surname', true, false),
    race: argum.object(options, 'race', false, 'human')
}

will again respectively set 'name' to 'Petar', 'surname' to 'Vasilev' and 'race' to 'human'.
