Dynamic Translation of Smalltalk to WebAssembly

Dynamic Translation of Smalltalk to WebAssembly

The article explores Smalltalk code translation to WebAssembly (WASM) within the Catalyst project. It details levels of Smalltalk, JavaScript, and WASM, focusing on direct Smalltalk to WASM optimization. A new translator, WATCompiledMethodTranslator, aids in this process, exemplified by a Smalltalk expression conversion. Creation of a WASM module for Smalltalk methods is explained, highlighting performance advantages and potential future comparisons with dynamic JS translations. Collaboration in the Smalltalk community is encouraged for further advancement.

Looks like the underlying project is not open source:

"WebVM is based on a CheerpX build that we host. We encourage users to deploy their own versions of WebVM, but we don’t currently allow self-hosting of the CheerpX engine itself. This public build of CheerpX is provided as-is and is free to use for technological exploration, testing and non-commercial uses. If you want to build a product on top of CheerpX/WebVM, please get in touch:"

Hi, Lead Dev of WebVM and CTO of Leaning Technologies here. Happy to answer any questions you might have... potentially in a few hours, it's quite late here :-)

Even better, consider joining our Discord: https://discord.gg/yTNZgySKGa

Let me fix the title: "WebVM is a wasm VM running in browser"
By @Animats - 3 months
Love the buzzwords.

It's a Linux command line environment running in a browser. Slowly.

Note that "CheerpX enables you to run existing 32-bit x86 native binaries". For some reason support for wasm64 (in browsers) has been stagnated for years, which is a pity.

Networking provided by Tailscale. Clever! Works around some potential issues.

This feels way slower than https://bellard.org/jslinux/

Cool, but very often my keystrokes aren't showing up, making this pretty unusable.

Also, for the use case of local dev environment for Web IDEs, this doesn't look fast enough.

    node --version
runs fast after the first time, but executing any JavaScript is very, very slow:

    user@:~$ time node -e "console.log('Hello')"
    Hello
    
    real    0m7.693s
    user    0m0.012s
    sys     0m0.000s

What a practical use case of such thing?

Can it be made to work offline and keep state locally between reloads?

Where are files located, server, client, browser local storage?

How do you import a .exe compiled elsewhere, curl, scp?

This is a Linux environment, but it can run Windows apps? How does that work?

First thing I tried was `apt-get install emacs` and it hung on downloading. Editor preferences aside, I assume any nonstandard package will have the same problem. Interesting idea, but apart from trivial glue you may not need more than a container or unikernel for anyway, I'm struggling to understand a practical use case.

Can we port Adobe Flash to WebVM to avoid having to pay for "CheerpX for Flash"?

I first used Slackware Linux off floppies in the mid 90s, yet every time I see linux in the browser I am gobsmacked.

I’ve said for a while that a browser is basically its own operating system. Now it can host operating systems!

Totally unusable on mobile unfortunately (at least Firefox and Chrome on Android). Might be a limitation of how the keyboard works, but every command gets duplicated (at least) when I enter it.

Seems like having tailscale or at least wireguard would be really useful in this

Hi, this looks really amazing, will give it a try later thanks

Sweet, could i run a nodejs http api directly from browser ?
By @marmaduke - 3 months
Can this run NFS or other network filesystems?
By @ptspts - 3 months
It doesn't work in my Chrome on Android. The cursor is blinking, nothing happens.

If a browser is not supported, the site should display a specific error message.

server-less - like the server that runs the browser that the VM runs inside.

/sarcasm

Now just needs some kind of hack for networking through a browser extension and this would be so awesome.
