LIPS VS biwascheme

Sweet, I'll have to give that a go :)

Another option in browser land is lips[0], which exclusively targets a js backend.

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.

Your example revealed a bug in my Scheme interpreter. This is an example that fails to match:

In my interpreter, LIPS Scheme, vector literal syntax is created using a syntax extension, a token that is mapped to a function or a macro. So you can use things like this:

I'm not sure about other Scheme interpreters but in my interpreter LIPS Scheme, there is (env) function that returns a list of symbols. You can also access environment objects e.g. (current-environment) return object that is used internally. And you can even access the scope chain because the env object has __parent__ property that returns the parent scope.

Few of my Open Source projects: * jQuery terminal * LIPS Scheme * Gaiman * Sysend * Wayne

(define promise (--> '>(fetch "https://lips.js.org/") (then (lambda (res) (res.text))) (then (lambda (text) (. (text.match #/\s*([^>]+?)\s*<\/h1>/) 1)))))

ngl when I first saw the headline my first thought was, “Wait, bring CAR into JavaScript? Make it a Lisp? But hasn't it already been done?”

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.

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).

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

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:
