Identifying the caller

[thierry]

Hi,

gs> .... when a handler is called,
gs> can its script identify its caller and if so how? I guess there is some 
gs> context description available but I don't know how to find it in the 
gs> docs.
gs> Obviously the engine does know this information - it's just a question 
gs> of if and how it's made available to the developer.

From time to time, i'm using this script which comes mostly
from some part of the Rev debugger.... don't remember in details :-)

So, anywhere you want to know the path of all the callers, just put

   PrintExecutionContexts "whateveryoulike"

in your script....
and it does the trick. But, as it comes from
*inside* Rev, and it's not in the Doc.... you have been warned :-)


Hope this help
Regards, thierry
