haXe 2

Time for action – Interacting with the user

Now, we're going to create an application that takes your name as a parameter, greets you, and displays the number of characters in your name.

1. Copy the following code in a file named Main.hx

   class Main
   {
     public function new()
     {
     
     }
   
     public static function main()
     {
      var name = neko.Sys.args()[0];
      trace("Hello " + name);
      trace("Your name is " + Std.string(name.length) + " characters long.");
     }
   }

2. Open a terminal; go to the directory where you saved Main.hx and type the haxe –main Main -neko characterCounter.n command.
3. Type the command (this is an example with my first name):

   neko characterCounter.n Benjamin

4. You will see the following output:

   Main.hx:12: Hello Benjamin

   Main.hx:13: Your name is 8 characters long. ...
