Hey Tucker,
The link that Raju sent does the following hack to use the Flash stack trace
output to parse out a function's name in AS3 (when debugging is enabled)
private function getFunctionName(e:Error):String
{
var s:String = e.getStackTrace();
var i:int = s.indexOf("at ");
var j:int = s.indexOf("()");
return s.substring(i + 3, j);
}
private function getCallingFunctionName(e:Error):String
{
var s:String = e.getStackTrace();
// trace(s);
var i:int = s.indexOf("at ");
i = s.indexOf("at ", i + 3);
if (i == -1)
return "caller unknown";
var j:int = s.indexOf("()", i + 3);
return s.substring(i + 3, j);
}
where the latter two functions are can be used like this:
private function doSomething():void
{
trace(getFunctionName(new Error()));
doit();
}
private function doit():void
{
trace(getFunctionName(new Error()));
trace(" called by", getCallingFunctionName(new Error()));
Could we do something like this in the deprecation method (or some
more general place in the debugger)
to print function names more informatively?
