Flex3 Improving basic trace

I read somewhere a utils to show the class + line nbr of the function who called a trace("foo") which is very handy once you start getting a lot of debug output.

Any hints on where to find it ? it was open source, maybe shown at a flex event.

trace("my debug");

> mydebug :34 bla.as3 ..

Thanks,

Greg

Solution

  • Here is a quick&dirty solution:

        private function mytrace(s:String):void {
        try {
            throw new Error();
        } catch (e:Error) {
            var arr:Array = e.getStackTrace().split("\n", 3);
            trace(arr[2] + " " + s);
        }
    }

    For mytrace("xyz") you will get:

    at Main/init() xyz

    or if you compile with "-debug=true":

    at Main/init()[C:\home\myproject\Main.mxml:120] xyz
