@a1ba@suya.place @cnlohr@chaos.social again, I think it's more of a language interface question (what does DOM API look like in C) than a wasm interface question

@ignaloidas @cnlohr it's already solved problem in another kind of wrapper: an operating system kernel.

It doesn't care from which language you call it unless you can emit syscalls.

@a1ba@suya.place @cnlohr@chaos.social right, but still - the wast, wast majority of software is useless without posix calls

sure, you can provide some interface to web apis, but you'll still often need to wrap libraries/posix to fit into web apis

so in the end you're just moving where you're doing the wrapping

@a1ba @cnlohr @ignaloidas Reminds me that even the most extremely basic profile of POSIX for embedded systems (PSE52) still requires a filesystem.

https://posix.opengroup.org/docs/pse52-2003.html
(Extreme because it's basically just turning POSIX into an extension of ISO C. Like there's nothing about shell & utilities or multi-user. That's in PSE54)

@ignaloidas @cnlohr the webapps written in javascript that your browser run right now doesn't require POSIX. And you know I wasn't talking about POSIX here.

Let me write interactive websites without JS dammit. Wasm could've been an alternative if the "web" in its name had _any_ meaning.

@lanodan @cnlohr @ignaloidas oh, yeah, that's a thing.

At least it kinda allows to run existing software, if you really need to

@a1ba@suya.place @cnlohr@chaos.social most of wasm's utility was and is in the fact that you can have a way to use existing, non-browser code in browsers

if you want to use wasm instead of JS - just get down for a bit to write the JS wrappers, and congratulations - you can now have a painful experience dealing with browser API's from other languages

@ignaloidas @cnlohr so basically, yes, emscripten is what we deserve.

And the only application for it is to run some 90s games stuttering in a single frame per second.

@a1ba@suya.place @cnlohr@chaos.social @ignaloidas@not.acu.lt And well, stuff like fopen() is part of ISO C, so without it… what you'd have is a subset of ISO C, at which point what the heck is that environment even from a portability point of view.

@lanodan @cnlohr @ignaloidas I started appreciating actually somewhat conforming environments after I've witnessed homebrew development on switch, psvita and psp.

In all three cases it's some random newlib + gcc port. newlib kinda okay for ISO C99-ish. But C++? Eh... POSIX? Don't even think about it.

It's an enormous amount of work, yeah. But I understand now why people don't maintain their ports for these targets for too long.

@a1ba @ignaloidas

Wasm is perfectly fine (except for that it's not ASM and doesn't allow goto). But for what it is it's perfectly fine, and great for web.

If it was bad, you wouldn't be able to make full 3D apps in C for 10kB (wrappers included).

(But really I will never stop being hurt by this thread https://github.com/WebAssembly/design/issues/796)

@cnlohr @ignaloidas and so could asm.js. And so can plain javascript.

if it all boils down to calling webgl why do I need an extra step with C if it's gonna be javascript anyway?

@a1ba @ignaloidas You can write and use c libs and apps. I would expect something like emdoom could just straight up run.

@cnlohr @ignaloidas and so, again, could've be done with asm.js long before wasm.

I want to write for web in single language. It means either C or JS should go away.

what problem wasm does solve? Yeah, using existing C code is cool but then you have another problem which is emscripten and all it's quirks

please read the thread, it's already has been discussed.

@a1ba@suya.place @cnlohr@chaos.social you understand that you don't have to use emscripten, right? Many don't.

It's just that nobody cares/wants to build websites from wasm alone

@ignaloidas @cnlohr sure, yeah, I can implement all needed stuff myself, but that doesn't really fall into category of using "existing C code", right?

At that point I can just hack it until it works or rewrite it in JS.

@a1ba@suya.place @cnlohr@chaos.social I mean, almost everything that isn't JS or Lua or similar is hopelessly tied to POSIX. You either reduce the stuff that's donw in other languages to end up as just simple processing routines, end up implementing emscripten yourself, or rewrite it in JS.

@ignaloidas @cnlohr exactly.
