test compatibility with ChakraCore

[pkra]

Just a note (not a priority for the team at this point.)

ChakraCore now supports OSX and Linux; there's also a node fork using ChakraCore.

Should be a fun thing to test for anyone interested.

I had a few minutes to procrastinate on this.

There are some problems with the browser sniffing code (for example below but there's more beyond that). After hacking the problematic parts and replacing their value with Booleans, at least one test passed (and some output looked ok).

I should add: npm install mathjax-node@v1.0.0-beta.0 failed so I grabbed mathjax-node manually and installed the dependencies by hand.

This looks to be the line

    isEdge:      ("MSGestureEvent" in window && "chrome" in window &&
                     window.chrome.loadTimes == null),

Perhaps changing that to

    isEdge:      ("MSGestureEvent" in window && window.chrome != null &&
                     window.chrome.loadTimes == null),

or just commenting out the is* lines of BROWSERS all together would do it.

Yes. After that, some other browser API gave errors so I just set a couple of things to true until it ran :hammer:

[pkra]

Sorry! Just re-read your post and yes, that's basically what I did.

With today's linux nightly build, chakra passes all the tests without the issues mentioned above.

Closing this as fixed upstream.
