/**
 Write a program that performs an HTTP GET request to a URL provided to
 you as the first command-line argument. Write the String contents of
 each "data" event from the response to a new line on the console
 (stdout).

 ----------------------------------------------------------------------
 HINTS:

 For this exercise you will need to use the `http` core module.

 Documentation on the `http` module can be found by pointing your
 browser here:
 /home/anca/lib/node_modules/learnyounode/node_apidoc/http.html

 The `http.get()` method is a shortcut for simple GET requests, use it
 to simplify your solution. The first argument to `http.get()` can be
 the URL you want to GET, provide a callback as the second argument.

 Unlike other callback functions, this one has the signature:

 function (request) { ... }

 Where the `request` object is a Node Stream object. You can treat Node
 Streams as objects that emit events, the three events that are of most
 interest are: "data", "error" and "end". You listen to an event like
 so:

 stream.on("data", function (data) { ... })

 The "data" is emitted when a chunk of data is available and can be
 processed. The size of the chunk depends upon the underlying data
 source.

 The `request` object / Stream that you get from `http.get()` also has
 a `setEncoding()` method. If you call this method with "utf8", the
 "data" events will emit Strings rather than the standard Node `Buffer`
 objects which you have to explicitly convert to Strings.

var http = require('http');

http.get(process.argv[2], function(res){
	res.setEncoding('utf-8');
	res.on('error', function(e){
		console.log(e.message);
	});

	res.on('data', function(chunk){
		 console.log(chunk);
	});
