wasmtime_serde VS extism

yes, it's perfectly possible, the biggest hurdle to this is that you need some way to map the data into and out of wasm memory, you can do this manually or use one of the crates that currently solve this problem (I'm author of a github)

(english is not my native language)I have a voxelgame project, and for this project I would really like to have wasm plugins to expand the game, the problem is that wasm only supports 32 and 64 bit integers and floats, and that is not enough for me to make an api for plugins, to to solve this problem you have the wit-bindgen project, and without a doubt it's an amazing project with very smart people behind it, the problem is that I couldn't get it to work right, it's a huge project divided into several crates in several repositories, and all no documentation, and I just wanted to pass complex structures through wasm as stupidly and simply as possible, so last week I made this stupid tiny crate to solve my problem, but I think it might be useful for other people github

Extism can be really useful for packaging up and running cross-language libraries!

The most clear information about it is at: https://extism.org, but its a bit focused on the primary use case for Extism, being a universal plugin system.

There is a C PDK (https://github.com/extism/c-pdk) which you'd probably want to use in a new wrapper around your library in C++, and compile it to wasm32 freestanding or WASI, but without emscripten. Extism doesn't currently have an interop layer to emscripten.

It may just be my own unique obsession to peek at the internals of .wasm, but if anyone else is curious:

u/nbittich - curious if you've tried to use your language as as a scripting language inside other apps? I took a peak at your browser wasm environment, and think we could hook up the `compute` entrypoint you have here[0], but I'm not certain what the `ctx` does without going super deep, and if it could be passed into an Extism function[1] (which is how I'd try to run it from within 16+ other languages).

Yep, this is one of the initial motivations for creating Extism: https://github.com/extism/extism -- and it works across 16 host languages & 8 guest languages.

On the devx, there's definitely some rough edges around building and using Wasm. My company has been working on a framework to ease integrating Wasm into existing applications. One area it focuses on is providing easy data passing between the host program and the Wasm and vice versa. https://github.com/extism/extism We do not have WASI preview 2 support yet, but are interested in integrating it.
