Provide a way to access script document information from host methods

[ClearScriptLib]

^{Originally posted by cyraid July 26, 2025} In a C# method, calling from Javascript, is there a way to get Module (Document) information? I have a Javascript Plugin System that works off of a single V8 Engine (so that plugins can import Modules from other plugins).

It would be nice if something like this existed:

public static class SomeClass {
  [ScriptMember("someMethod")]
  public static void SomeMethod(V8DataOfSomeSort v8Data) {
    // v8Data.CurrentDocument.HostData
  } // Procedure //
} // Class //

//...

engine.AddHostType(typeof(SomeClass));

// Execute engine Module stuff here, then tie in a "HostData" (the plugin instance) to the Module on the C# side.

In Javascript (let's say were are in a Module):

SomeClass.someMethod();

I have a logging system, and it would be nice having which plugin the debug information is coming from when it outputs to the logging view.
