Specifying global object (globalThis)

[JasonBarnabe]

I'm trying to create an environment for scripts that expect to be run in browsers. I can define window, but that doesn't help when the JS is looking at location or document or any other number of things. I presume things like that work because window is the global object, and they're defined there (window.location, window.document, etc.)

Is there a way to specify the global object?

I am sure libv8 has some tweak to make this happen, we do not have it exposed though. Maybe walk all the props on window and set them as top level vars?

Yeah, that's the backup plan.

I am guessing it is something like this:

https://github.com//blob/e5e8685c15494da58112fc1ab76e2dfc15fbf728/test/cctest/test-api-interceptors.cc#L3185-L3185

I support a PR that gives us something like this I guess?

context.global = "{a: 1, b: 2 }"
puts context.eval("a") => 1
