Should be mergable into LDC master then! I could definitely formalize things a bit, but any patch of this kind would quickly be obsolete, as Emscripten catches up with LLVM versions. Moreover, I don't feel comfortable polluting LDC with the specificities of some obscure use case (as cool as this use case can be!). It might be preferable - though harder - to patch Emscripten so it aligns on LLVM official API versions.

I would be interested to have a look into the "PNaCl legalization passes" problem. That would be great, and might simplify the toolchain a lot. First we must get the build to pass again ; I'm working on it at the moment, I have a patch to making the build work (only for the binary "ldc2", not other tools of the package). I can send it to you if you want.

Re: Running a D game in the browser
Very cool! Is it's possible now to write not graphical Apps for web in D? I do not need graphics, but I need normal language instead of js that can help me to do some computation. For example is it's possible to write in D app that would validate some fileds in HTML and simply show (even on console) information about data in them.

Cool. I think the D Foundation should actively support stuff like this (once funding and resources are secured). Mobile (iOS/Android) and asm.js. That's where huge shares of the market are, it's a "must have". PS I don't like WASD in the game, I'm not left handed ;)

Oh, I read it wrong, the score is reset. Dummy, me! It's just that you're becoming better at this silly game :-) Thanks for your replies! As Mark guessed, I didn't spend a lot of time on the game-design side (but I'm still interested in game-design related comments). It's more of a proof of concept, using D. Using C++, there already are impressive demos: https://kripken.github.io/BananaBread/wasm-demo/index.html

Interesting but a bit lame. 1. The movement should continue in the same general direction, if not exactly the same. It is impossible to avoid something that can do anything. 2. The movement shouldn't accelerate so fast, it's harder to control where you want to go when if you hold the key down a you end up on the other side of the screen. Of course, I doubt this was a game intended to be fun ;) The good news is that you have a lot of upside. Consider making a video player... replace stinking flash! Could create better websites by having more programmatic functionality, etc.. (more app like websites) The upside, from the initial looks, seems to be quite good if you go in that direction.

I know virtually nothing about compilers and even less about Emscripten, but the fact that you managed to get a D game running inside a browser is plain awesome. Congratulations!
