Great little debuging snippet found while browsing. The code adds different coloured borders to the assets depending on its level. Leave commented out if not needed.

How to identify at runtime if the swf is in debug or release mode/build

It may be interesting to know at runtime whether an application is running from a debug or release SWF file. It allows the application to automatically execute debug specific code when the file is a debug SWF file and ignore this code when it is published as a release file. Also, it should be nice to know if you have a debug flash player just for the same reasons. But for the last one, there is a function in the Capabilities class called isDebugger.

One solution would be to use conditional compilation. The other solution is in the following code (hack).

package org.adm.runtime
{
	import flash.system.Capabilities;
 
	public class ModeCheck
	{
		/**
		 * Returns true if the user is running the app on a Debug Flash Player.
		 * Uses the Capabilities class
		 **/
		public static function isDebugPlayer() : Boolean
		{
			return Capabilities.isDebugger;
		}
 
		/**
		 * Returns true if the swf is built in debug mode
		 **/
		public static function isDebugBuild() : Boolean
		{
                        var st:String = new Error().getStackTrace();
			return (st && st.search(/:[0-9]+]$/m) > -1);
		}
 
		/**
		 * Returns true if the swf is built in release mode
		 **/
		public static function isReleaseBuild() : Boolean
		{
			return !isDebugBuild();
		}
	}
}

This code simply searches for line numbers of errors in StackTrace result. Only StackTrace result of a debug SWF file contains line numbers. Then we know that we are running a debug or release SWF file.

This class is also available in the Components Pack at Runtime subpackage
