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.

Fascinating!

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.

I created a dedicated github branch "fastcomp-ldc".
The patch: https://github.com/Ace17/dscripten/blob/fastcomp-ldc/ldc2.patch

That patch doesn't look too bad.
Could you introduce a CMake option for building with Emscripten-fastcomp?
And a #define "LDC_LLVM_EMSCRIPTEN" or something like that, so that you can change `#if LDC_LLVM_VER >= 309 && 0` to `#if LDC_LLVM_VER >= 309 && !LDC_LLVM_EMSCRIPTEN`.

Should be mergable into LDC master then!

cheers,

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.
