Announcing Wasmer 1.0, the mature & fast WebAssembly runtime; with 3 compilers, 2 engines and ton of new features!
1 project | /r/Python | 29 Jan 2021

Not to add more confusion but to promote a cool project, there is wasmr which allows to run WebAssembly inside R, just like Wasmer Python embedding allows to run WebAssembly inside Python. Just wanted to mention this project because we are talking about R :-).

https://github.com/WebAssembly/wabt/blob/main/wasm2c/README.... is a straightforward way to take an untrusted application (compiled already to wasm) and turn it into C that you can embed into your application or compile to a linkable DLL. I believe this approach has been used to sandbox untrusted libraries in production by Mozilla: https://hacks.mozilla.org/2021/12/webassembly-and-back-again...

This seems sort of like understanding machine code vs assembly; it's much easier to learn WAT and translate to/from WASM as necessary using the wabt tools [0].
Either way its super cool how simple WebAssembly is, you can really get your hands dirty and understand exactly every detail of how your program runs!

You mean this? https://github.com/WebAssembly/wabt/blob/main/wasm2c/README....
That seems like quite an undertaking. But at that point, It would make sense to cut out WASM entirely like https://datastation.multiprocess.io/blog/2022-05-12-sqlite-i...

I don't think you are building an application that will use Native Client technologies How to extract source code from Native Client .nexe file, migrate to WebAssembly? #1864 so that would be superfluous, and frankly, useless in your case.
Hey Rustaceans! Got a question? Ask here (5/2023)!

I'm trying to get a basic Rust webassembly program, then porting it to C via wasm2c. The example works, but when I use wasm-bindgen and analyze it with wasm2wat, I get an import "env". The issue is that in C (wasm2c) it comes out as struct Z_env_instance_t; and I can't instantiate it (as in Z_env_instance_t env; to pass it's address to Z_wasm_client_bg_instantiate.
