Allo:
I just noticed the following thing, when I'm debugging dynamic code that is
run inside an eval() (I do that by setting a breakpoint at pc == 0), It
seems that frame's scope [JSDIValue] contains 0 properties.
Im trying to save the variable stack for every line executed of the dynamic
code.
So my code to get those variables is (inside onExecute method
from jsd.breakpointHook )
*onBreakPointExecuted (frame, type, val) {*
* var listValue = {value: null}, lengthValue = {value: 0};*
* **frame.scope.getProperties(listValue, lengthValue);*
*... code ...*
*
*
*}*
*lengthValue.value is 0*
*
*
*The point is when I run that code for a normal breakpoint ( I mean a
breakpoint a declared function call) It works fine and It list all the
variables that the function uses.*
*So. Maybe I'm not looking at the right spot or maybe is not possible to get
that information from the code.*
*
*
*Thanks in advance.*
*Lautaro*
