WASM demos on Mac OS X

[erlend-sh]

I'm getting this when I'm trying to run the demo:

What OS and browser? On Ubuntu 18.04 LTS, Chrome 78.0.3904.97, it works.

[erlend-sh]

MacBook Pro 2019, Firefox. Can’t get the exact version right now.

Does the example run if I you use an HTTPS link? I added SSL to the host a while back, and have slacked on adding it to all of the links in the book (and whenever I point people at the tutorial).

[erlend-sh]

Tried both http and https in latest Firefox, Chrome and Safari on MacBook Pro, Catalina v10.15.1

2,3 GHz Dual-Core Intel Core i5
Intel Iris Plus Graphics 640 1536 MB

All I get is this black screen. It's probably not related to the "connection not secure" warning then so feel free to change the title. I checked on a different, older MacBook and couldn't get it to work there either. Has anyone with a macOS machine gotten it working?

I'll see if I can borrow my wife's Macbook this evening to give it a look. Hopefully, I didn't pick a GL mode that isn't happy on OS X!

I managed to get to use a Mac last night, and can confirm that this is an RLTK-level issue: the canvas opens, the WASM executes and logs keystrokes, but nothing gets rendered - just a black box.

I'll open an RLTK issue and link it to this one, and see about getting a library-level fix in ASAP.

I believe the issue is fixed in RLTK, pulling and rebuilding the tutorial now.

I'm happy to report that the demos are running on my virtual Mac:

The RLTK changes ended up being very substantial; there's basically a whole new WebGL pipeline now. It's single-pass (or one pass per console layer), the post-process is integrated into the main loop, and it works by sampling dynamic textures rather than a giant vertex buffer - so it's really rather fast.

If anyone could confirm that they are working on a real Mac, I'd appreciate it!

[erlend-sh]

Just confirmed it’s working, thanks so much for the quick turnaround! 👏

Latest Firefox and Chrome both work. Safari does not, which I assume is because their WASM support remains incomplete.

[thebracket]

I'll go ahead and close this out, then. Thanks! (I'm told that Safari support is a pipe-dream, due to lack of WebGL 2 support - so I won't stress that one.)
