wasm-lisp VS wasm-bindgen

It is a lot, but not quite 1000, yet. From https://webassembly.github.io/spec/core/appendix/index-instr... I see 436 instructions including SIMD which is over half the population. If I filtered it correctly, it looks like there are about 203 instructions in Wasm without SIMD. Many of those are not necessary for most programs.

There at least three small Wasm interpreters in Rust

This list has 169 Wasm instructions https://github.com/rolfrm/wasm-lisp/blob/master/instruction....

Wirth's RISC is neat, I'd love to re-do it in RISC-V (only 47 instructions in the base ISA). UM, Chifir and UXN look like Art (not pejorative), I'll definitely read the Chifir paper. They would be great systems to run on top of Wasm.

One might be able squeeze a Chifir VM into an ESP-32 (with external PSRAM).

Another strange issue could be seen in the strict class heritage organized definition of the DOM, which can not be handled very well by rust because of a still unsolved bindgen issue (#210).

For a much simpler but less flexible approach there's wasm-pack for creating JS packages from Rust, and wasm-bindgen for easy interop. Both have very good documentation.

We encountered quite a few hurdles on our journey. For one, we had to build our own yew-webtransport and yew-websocket integration from scratch by adding WebTransport definitions to wasm-bindgen (pull request link). We also had to add WebTransport support to the h3 crate (pull request link). co-created by @ten3roberts

Go with your WebAssembly module idea. Since it sounds like your chess engine does not draw a UI, it shouldn't be too difficult. wasm-bindgen will be your best friend.

I've never tried it, but apparently some bindings exist, e.g. https://github.com/rustwasm/wasm-bindgen

So you can either try manipulating the DOM w/ some bindings or draw to canvas.

Google also brings up this GitHub issue.

If you want to learn more on wasm-pack, there is a wasm-pack book as well as some fairly detailed wasm-bindgen docs. There are a few resources for learning Rust itself in the December newsletter. Finally, please get in touch if you would like to see more content on Deno and Fresh. I hope you found the content useful and am keen to hear about possible improvements.

Love the article.

In my mind I see the problem of dynamic linking in rust to have a bunch of overlap with the "I want this rust library to be exposed in my higher level GC'd language with minimal safety/handwritten bindings" problem.

My hunch is that the lack of expressiveness of the C ABI is holding back both. the thing I'd love to see some sort of "higher level than the C ABI" come out. And something like `wasm-bindgen`[0] to exist for more languages.

Here's a link to the rust "interopable_api" proposal! I don't understand all the implications, but it seems to be in the right direction https://github.com/rust-lang/rust/pull/105586

Rust has https://github.com/rustwasm/wasm-bindgen and https://crates.io/crates/sledgehammer, the latter of which batches together JS calls to reduce the FFI cost. https://dioxuslabs.com/ uses these to great effect.

This seems like it could be super useful for integrating with wasm-bindgen and TypeScript. Last I checked, the types generated by wasm-bindgen left a lot to be desired (no disrespect intended, wasm-bindgen is an awesome project). A few years ago, I contributed the skip_typescript attribute to wasm_bindgen that allowed you to override the type generation by hand-writing your own types (using a custom typescript section), but I wonder if this could simply generate higher quality types without the manual intervention.
