wajic VS dos-like

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.

I’m assuming “DOS feel” means there’s no dynamic linker so the implementation has to be contained in header files?

So when I had some spare time the past weekend, I decided to do something a bit different: bring to Rust an existing framework that lets you write applications which look like they are DOS applications. dos-like, made by Mattias Gustavsson, is like a small engine for writing modern applications with the look & feel of MS-DOS programs. So basically, when using this framework, we end up with applications that run on modern hardware and operating systems all the same, but with deliberate video effects and audio that bring us back to that era, including large pixels, CRT distortion, text and graphics video modes, and synthesized (Sound Blaster 16) or MIDI (Sound Blaster AWE32) music. It was written in C, mostly as a single file with some other statically linked dependencies. The project also comprises a few fun examples, such as a proof-of-concept FPS inspired by Wolfenstein 3D, a point-and-click adventure, a voxel renderer, and even a music tracker.
