Executing scripts in different scopes?

[JamesB7]

Hello,

I would like, when executing a script, it to use a specific object. I don't want to get rid of the global object, I just want functions that the script defines to go into that specific object. Kind of like the window object on a browser. In this case, I have multiple scripts and multiple objects and I want them to share a global state but still contribute their own functions to particular objects I define.

How would I go about doing this in Jurassic? (Aside from modifying the code being executed itself. Problem there is it'd mess up debug line numbers, etc.)

Thanks,

James

I think the window object is just a reference to the global object i.e.

Function('return this')() === window // returns true

Have you tried something like this (untested)?

var scope = ObjectScope.CreateRuntimeScope(null, yourScopeObject, providesImplicitThisValue: false, canDeclareVariables: true);
GlobalObject.Eval(scriptEngine, "some JS code goes here", scope, thisObject, strictMode: true)

yourScopeObject is the object you want to use instead of the global object. thisObject is the value of the this keyword.

I looked on the object I set as yourScopeObject, and I don't see the functions I defined. Is there anything else I ought try? Essentially, if I say

function xyz() { }

I am hoping it will define the function on yourScopeObject. No luck so far.

(Also, FWIW, CreateRuntimeScope's documentation says the first parameter may not be null.)
