I am working on a migration platform to migrate web applications from a device to another. I am extending it to add the support for preserving JavaScript state.
My main task is to create a file representing the current state of the executing application, to transmit it to another device and to reload the state in the destination device.

The basic solution I adopted is to navigate the window object and to save all its descendant properties using JSON as base format for exportation and extending it to implement some features:
  • preserving object reference, even if cyclic (dojox.json.ref library)
  • support for timers
  • Date
  • non-numeric properties of arrays
  • reference to DOM elements


The most important task I need to solve now is exportation of closures. At this moment I didn't know how to implement this feature.
I read about the internal EcmaScript property [[scope]] containing the scope chain of a function, a list-like object composed by all the nested activation context of the function. Unfortunately it is not accessible by JavaScript.
Anyone know if there is a way to directly access the [[scope]] property? Or another way to preserve the state of a closure?
