digitalmars.D.announce - compile D to asm.js using ldc --betterC and emcc

I wrote a little working demo that shows how to use D inside 
firefox.

It uses emscripten(emcc) and ldc.

you mean build everything and commit?

I've just added the binaries, I can't add the whole chain, its to 
big.

Judging by looking at that build script, sure that's simpler than 
what I read you had to do some time back! You had to switch to 
some legacy llvm and compile the indermediate first to C and only 
then to Asm.js.

This looks like powerful enough for normal use. You still miss 
DRuntime but a lot better than using C to do the same. Perhaps 
even better than Typescript in some cases?

Can someone explain the reasons why LDC can't compiles to webasm 
with the DRuntime?

Nobody has done the work to port it, though someone has expressed 
interest and opened an issue for it:

https://github.com/ldc-developers/ldc/issues/2144

Regarding porting druntime, I'm told by some here that there are 
some issues with the GC and thread-local storage because of the 
particular wasm instruction set, but I've never looked into it.
