biwascheme VS racketscript

If Scheme is something you enjoy, BiwaScheme's interpreter can be instantiated from within Javascript and can be used to evaluate Scheme code.

This project is very exciting. In the meantime, there are a couple of options:

BiwaScheme: https://www.biwascheme.org/

Advantages: written in JavaScript, with excellent JS interop. Project has some history.

Disadvantages: slower than S7 (though still plenty fast for many uses), less-complete (e.g., no syntax-rules or syntax-case, though it does have its own define-macro).

S7 Scheme: https://cm-gitlab.stanford.edu/bil/s7

Written in C, but can be transpiled to WASM (see https://github.com/actonDev/s7-playground/ )

Advantages: This project also has some history. Considerably faster than BiwaScheme.

Disadvantages: JS interop is clumsier (basically the same issues as JS interop with any WASM code... this could probably be mitigated considerably if someone wanted to take the time).

For Scheme implementations there are LIPS and biwascheme. I haven't done more than play around with them, so I can't really give an informed opinion about pros and cons or favorites.

I used to have hundreds of open tabs. From there I kept repurposing it to do more stuff with the browser until it reached its current state, where I want to make it a "extend firefox from Emacs" thing. It kinda do that already, but extending the firefox-extension itself require the extension to be re-built (so you need whole javascript tooling, rebuild and reload the addon etc). I am considering adding something like biwascheme to it soon to work around that.

And then users can just use biwascheme and run programs in mainframes and their smart toasters

Languages like Biwa Scheme and LIPS Scheme are good for running Scheme in the browser. But I would prefer compiling Scheme code to JavaScript in the server, then serving the compiled JavaScript image to the browser.

Just a note that even BiwaScheme doesn't fully implement call/cc, it doesn't save the whole environment when capturing.

Very cool! Do you know how this compares with Biwascheme? https://www.biwascheme.org/

Biwascheme has some weird scoping bugs that makes me a litte afraid of using it for serious stuff. It seems nixe and all, but this: https://github.com/biwascheme/biwascheme/issues/125 is not very confidemce inspiring.

There is another schemey language that compiles to JS that accepts things like this:

    (when (start-are-aligned?)

I don't think there's any mature projects that compile to WASM yet, but there's been some steady progress on that front. There's also a dialect of Racket that transpiles to Javascript and a #lang that lets you write Javascript using Racket syntax.

The github page has more information: https://github.com/racketscript/racketscript

And to answer the questions every Schemer will have, no the runtime doesn't yet support tail calls or continuations.

You can use Racket in the browser with RacketScript

https://github.com/racketscript/racketscript It's still labeled experimental but in much the same way that Gmail is still technically in beta.

You could try Racket on the client side…with RacketScript: https://github.com/racketscript/racketscript
