wajic VS wasm-fizzbuzz

This is a slim alternative to Emscripten which focuses only on the C/C++ <=> JS interoperability part:

There's actually a super interesting project called wajic here:

https://github.com/schellingb/wajic

It's basically clang plus wasm-opt and some magic pixie dust which enables some of the most important features of Emscripten, but without the whole 'technology zoo' :)

There's now an interesting alternative to Emscripten called WaJIC:

https://github.com/schellingb/wajic

Enables most of the "Emscripten magic" (like embedding Javascript code into C/C++ files), but in a more bare bones package (apart from clang it essentially just uses the wasm-opt tool from Binaryen for post-processing).

(to be clear, wajic has fewer out-of-the-box features than Emscripten, but it might be an alternative for very small projects which don't need all the compatibility shims which are coming with Emscripten, while still providing tools for calling between C/C++ and JS.

Since I haven't seen it mentioned in the comments yet, here's another interesting project in the general area of "WASM without Emscripten":

https://github.com/schellingb/wajic

This provides an alternative implementation of Emscripten's EM_JS() magic (embed Javascript snippets right in the C/C++ source code), but without the Emscripten SDK. It still needs some additional tools next to Clang, so it sits somewhere between "pure Clang" and "full Emscripten SDK".

Alas, although there is WebAssembly support in the original dos-like, it is still not supported in the bindings for Rust. It would require a Rust toolchain to integrate with WAjic, which I am pretty much unfamiliar with. If you have any idea on how to achieve this, I would love to know.

There are some really interesting parts around sending commands to WASM applications in there, I would encourage you to explore those yourself, along with the super interesting article by Cornelius Diekmann on porting DOOM to WASM I mentioned earlier.

The framebuffer idea is used in this wasm doom port: https://github.com/diekmann/wasm-fizzbuzz/tree/main/doom

WASIX already does all the other stuff you mentioned, including in the browser. The one thing it's missing is GUI, mainly because there's no standard GUI interface in POSIX.

These are also good resources on using wasm without dependencies:

Wow, the linked porting of DOOM to Wasm, https://github.com/diekmann/wasm-fizzbuzz/tree/main/doom, is really an excellent read as well.
