Using Params Library

This library provides an options parsing function.

$3

node . --long-option-with-value a-value --long-option-without-value-is-enabling -s "short" input1 input2 input3...

Example Usage

``nodejs
// import the Params class
var Params = require('node-programmer/params');

var params = new Params({
"long": "long",
"port": "8080",
"host": "localhost",
"static": "./static",
"views": {default: "./views", short: "i"},
"forward": false
});

/**
* All the necessary arguments are included in the "opts" object
*/
var opts = params.getOpts();

/**
* Opitons (Parameters / Arguments) count equals to the number of specified arguments,
* not the total count of all parameters you pass them to program from the command line
* And the empty parameters will be ignored, and not included in the option count
*/
var optCount = params.getOptCount();

// do something if you don't get the right number of arguments
if (optCount < 1) {
console.error("Not enough parameters provide");
// print out the usage before exiting the program
process.exit();
}


// getting all the inputs, which is an array type even only one input is provided
var inputs = opts['---'];

Also you can see [this project][https://github.com/tyolab/table-exporter] for example usage.
