FYI, I trad-coded a .wit parser in Kotlin. It’s about 2,000 lines of code and it successfully decodes all the WASI .wit files. I’m intending to use this to built a host-side component model support, to complement Kotlin 2.4’s guest-side component model support.

This is not yet a standalone open source project, but if anybody wants that, I’m happy to do that work.

TIL trad-coding.

[curioustechizen]

And TIL wasmo. Of all the ways you could have announced the project to the world, this is the one you choose? 😄

[jessewilson]

I'll do a proper announcement when it does something useful! We're not there quite yet

@jessewilson 👍 Thanks for sharing!
We will need something like that in the future. (cc @Jim Teichgräber)

I’ve extracted this project into a standalone GitHub here:
github.com/wasmcomputercompany/brevity

[jessewilson]

We hit a nice milestone today:
1. We declared a concatenate() in .wit ,
2. Brevity generated a commonMain interface plus lots of tricky bridging code
3. We implemented it in wasmWasiMain
4. We called it from jvmMain via Chicory.

[jessewilson]

Although that works, that’s a pretty thin spike and there’s a lot of important work to do before this is useful. For example, we don’t yet cover such types as future or tuple or even bool.

[jessewilson]

Medium-term goal is to replace Chicory with either Endive or Cranelift (via Java FFM)

[jessewilson]

I’d also like to somehow make async work, though I need to wrap my head around the semantics of that

[jessewilson]

If this is at all useful in Kotlin’s own implementation of the component model, I’d love to contribute it. When it’s ready.
