This is a modified version of JSON in JavaScript which adds an option to pretty print the JSON output.

  object.toJSONString(prettyPrint)
  array.toJSONString(prettyPrint)
    prettyPrint ... if set to true the resulting string will be formated
                    with tabs and returns to be more human readable.

Here is an example data object:

   var data = {
      "eins" : "Eins",
      "int" : 2,
      "number" : 2.234,
      "obj" : {
         "a" : "A", b:"B", c:"C"
      },
      "array" : ["eins","zwei","drei",{"vier":4,"null":null,"undefined":undefined},{"vier":4,"null":null,"undefined":undefined},"zwei","drei",{"vier":4,"null":null,"undefined":undefined}],
      isBoolean : true
   };

data.toJSONString() will ouput:

{"array":["eins","zwei","drei",{"vier":4,"null":null},{"vier":4,"null":null},"zwei","drei",{"vier":4,"null":null}],"eins":"Eins","obj":{"a":"A","b":"B","c":"C"},"number":2.234,"isBoolean":true,"int":2}

data.toJSONString(true) will ouput:

{
	"array" : [
		"eins",
		"zwei",
		"drei",
		{
			"vier" : 4,
			"null" : null
		},
		{
			"vier" : 4,
			"null" : null
		},
		"zwei",
		"drei",
		{
			"vier" : 4,
			"null" : null
		}
	],
	"eins" : "Eins",
	"obj" : {
		"a" : "A",
		"b" : "B",
		"c" : "C"
	},
	"number" : 2.234,
	"isBoolean" : true,
	"int" : 2
}

why i did it?
on the client side it doesn't seem to make sense to pretty print the JSON output, because in most cases you will send it back to a server. but we use the script on the server side (using Helma/Rhino) so it makes perfectly sense for us.

exciting news. what that means is that in difference to other vendors (xbox 360) it will be possible to use wii as a cheap open web setop box - that is state-of-the-art and well documented. hopefully they will also support flash and/or video/audio embeding. everybody (not having a contract with nintendo) will be able to provide special formats and content for wii - personaly i think surfin' on a tv is the more useful scenario than browsing on a (slow and tiny) mobile.
