When you’re developing an Actionscript project – Flash or Flex – you cannot live without a decent debugger. Flex provides quite a good debugger and the Flash IDE has also a reasonable debugger. The problem with those debuggers is that you have to build explicitly for the debugger. So when you’re deploying on a remote server, you don’t have those debug options.

The ASDebugger allows you to trace variables. It has support for strings, integers, arrays, dates, arraycollections, objects and everything in between.

Usage is simple, import the asdebug.as class in your application and call the debugger:

import nl.flplibrary.debug.ASDebugger;
import mx.collections.ArrayCollection;	
 
private function simpleDebug():void {
	ASDebugger.debug("<b>test</b>");
}
 
private function advancedDebug():void {
	var o:Object = new Object();
	o.my_string = "<i>string</i>";
	o.my_number = 123.456;
	o.my_int = parseInt("1");
	o.my_array = ["item 1", "item 2", "item 3"];
	o.my_arraycollection = new ArrayCollection([{label:"item 1", data: 1},
												{label:"item 2", data: 2},
												{label:"item 3", data: 3}]);
	o.my_object = {	label1:"item 1", data1: 1,
					label2:"<i>item 2</i>", data2: 2,
					label3:"item 3", data3: 3};
	o.my_date = new Date();
	o.my_xml = new XML();
	o.recurse = o;
 
	ASDebugger.debug_prop(o);
}

Before running the application, startup the ASDebugger. The ASDebugger comes in different flavors:

• In a .exe projector file;
• In a .swf;
• As an AIR application;
• or you can even use the ASDebugger on this page!

And here it is:

Use this swf to test it:

Now, there are some limitations to this debugger. For instance, you cannot send MovieClips to it, it will simply always return ‘undefined’.

Also, there’s a limitation to the size of an object, it may no exceed more than 64k.
