Re: [Flashcoders] Get Original Variable's Name in Function?
This isn't possible, because local vars typically (that is, in
function2 which is used for class methods) become registers in the
bytecode, i.e., the name you give a local var won't be included in
your SWF *at all*, they are physically missing in the compiled SWF.
The old function tag used named variables (getVariable, setVariable),
but those string identifiers aren't accessible, either.
You can have a look yourself, simply name a var something you don't
use for a property anywhere (say, "asdasd") and search it in the
output of flasm or swfmill. It won't be there. As a simpler test, use
a longer name and observe the file size not getting any bigger.

var foo:String = "ABC";

myFunct(foo);
myFunct(moo);
In the above, how can myFunct know that the first call was sent 'foo'
and the second call was sent 'moo'?

Re: [Flashcoders] Get Original Variable's Name in Function?
Hi Doug,
I tried to do something like this a while back. I didn't know enough
about prototype based languages to get it working. Now that I know more
I think you may be able to do it but you would have to find a back into
the scope you were in when you called it. Here are a couple of things to
keep in mind:
1. since AS2 is a prototype based language you could possibly create a
new Function prototype. When the the function is created you would keep
a reference to its local scope. Then in your TraceMe function you would
use something like this:
function TraceMe(myVariableName) {
var strOut = myVariableName + ":" +
arguments.caller.myscope["myVariableName"];
trace(strOut);
}
You could also try creating the scope reference in the Delegate class.
2. You would also use the ASSetPropFlags to be able to see hidden
variables and make unwritable functions or variables writable.
3. You may find some ways to get to the local scope in the
mx.utils.Delegate class.
I don't really have time to do this obviously, which is why I'm passing
this info on to you but it may be possible.
Here is the class I made that I have used for tracing things,
http://www.judahfrangipane.com/?p=16. It's early work but it works.

Lee, Terribly sorry about that. I'll tell my email delivery system to be a bit faster next time, shall I..?

RE: [Flashcoders] Get Original Variable's Name in Function?
The problem here is, if the variable is not constructed as the property
of an object, then the name is not kept. For example:
class MyClass
{
public var pvar:String = "fine";
public function MyClass()
{
var lvar:String = "not fine";
tracethis(lvar);
tracethis(pvar);
}
}
While pvar will have its name somewhere in the instanced objects, the
lvar will not. This is because flash will drop the naming as its scope
is at the function level and so is not important.

RE: [Flashcoders] Get Original Variable's Name in Function?
I'm trying to create a _root level trace function where I can simply
pass a variable to a protoype function and it prints out the variable
name and value. Here is the pseudocode for what I want to do:
MovieClip.prototype.TraceThis = function(str){
Trace(str.Name + ": " + str.Value);
}
var myVar:String = "This is my value";
TraceThis(myVar);
Simple function that would save time when developing by allowing me to
just pass a variable and it would spit out both the name and value
without me always typing it out (trace("myVar = " + myVar).
I guess I'm lazy...

RE: [Flashcoders] Get Original Variable's Name in Function?
If I understand you requirements, you are trying to work out where the
data was passed to the function... your best bet is to use
arguments.callee to work this out.

Why would you need to know the variable name? It sounds like something
has gone heinously wrong with your code if this need is popping up.

Greetings all,
Is it possible to retrieve the name of the variable passed into a
function? For instance:
function myFunct(str:String){
// GET ORIGINAL NAME of str?
}
var foo:String = "ABC";
var moo:String = "DEF";
myFunct(foo);
myFunct(moo);
In the above, how can myFunct know that the first call was sent 'foo'
and the second call was sent 'moo'?
Thanks,

I guess the easiest way is to pass a string reference:
function myFunct(str:String, varName:String){
trace(varName+" has value of "+str);
}
var foo:String = "ABC";
var moo:String = "DEF";
myFunct(foo, "foo");
myFunct(moo, "moo");
That probably isn't what you're trying to achieve though. What exactly are
you trying to do?
