  • Extism Makes WebAssembly Easy

    While it'd be a nice addition, I wouldn't expect it any time soon.

    It's currently still a stage 1 proposal, while we've been waiting for years for other proposals to be merged. The last time a proposal was actually finished was over 2 years ago.

  • Show HN: Unity like game editor running in pure WASM
    9 projects | | 26 Sep 2023
    Do you know anything about any WASM developments that will enable pure WASM interaction with browser's Web-APIs at no or at a low cost without the JS layer? I'm looking at and it's very confusing. There are type imports, almost complete GC proposal(which apparently only for GCd languages, but not for anything browser<->wasm), the component model(which looks and sounds as something not for the browser use case), JS String Builtins (which will provide faster JS strings, but not DOM) and ECMAScript module integration (which will turn WASM modules into ES modules, but Web-APIs aren't ES modules so no luck). Sometimes I read contributor interactions and it looks as if providing such functionality isn't their priority or even in their plans, and WASI + component model for cloud and similar use cases are more important.

    And for Go, the proposal project on Github has many interesting conversations from the devs.

    And as a reminder to anyone interested in using Go WASM, it’s experimental and does not come with the same compatibility promise as Go itself:

    Seems like an awefully long time for progress to be made, given all the possibilities it would unlock.

  • Directly compiling Scheme to WebAssembly: lambdas, recursion, iteration
    5 projects | | 31 May 2023
    The proposal was recently bumped to stage 4 (the penultimate stage) with at least a couple of runtimes working on implementing (besides v8, which has supported it for quite awhile now)

    But basically it boils down to the memory control proposal, which can be found here and is not very far along; Webassembly proposals lists it in stage one.

  • Extism: Make all software programmable with WebAssembly
    14 projects | | 1 Dec 2022

    A glance of the overview and spec seems to indicate that WASM will provide some primitive data types, and any GC language can build their implementation on top of it. As I understand it, it's heavily based on Reference Types[3], which allows acting on host-provided types, and is already considered part of the spec [4]. It doesn't remove the need for the 5 different runtimes to have their own GC, but it lowers the bulk that the runtimes need to carry around, and offloads some of that onto the WASM runtime instead.


  • Announcing Wasmer 3.0
    2 projects | /r/programming | 24 Nov 2022
    There are proposals to make things easier so you don't need the compiler to generate all the JS gluecode to expose the browser API to WASM programs, but that as far as I know is not yet stable. WASM proposals include things like a GC and Threads... So it will look more and more like a high level bytecode overtime, very similar to JVM bytecode.
