Question

After using functionality from this question for debugging I am wondering is there a way to get the file name from which the function was invoked and may be the line.

May be I am asking for too much, but I know that in some of the languages it is possible.

If this is not possible can anyone mention why his functionality was not implemented?

I will try to rephrase the question, because I think I didn’t make myself clear.

I have file.js in which on the 17-th line there is a declaration of the function:

...
function main()
{
   Hello();
}

I have another file test.js, where I define function hello

function Hello()
{
  ...
  which tells me the name of the file and a line in which the function which evoked it was defined
}

So for example if I will call
main(), it will tell me file.js, 17 line

It has nothing to do with firebug

If all your doing is debugging, hy not just use the debugger built into modern browsers?

That line is all you need. You can examine the callstack, inspect variable values, and even run code in the current scope.

Such functionality makes your request kind of unnecessary.
