advent VS LIPS

A more interesting example: https://www.youtube.com/watch?v=i_zDbInYOpQ

AoC solutions here: https://github.com/lukechampine/advent/tree/master/2022

(The language has builtin commands for fetching inputs and submitting solutions)

FWIW I finished AoC 2020 in Go -- but I had 5 years' worth of helper functions to prop me up: https://github.com/lukechampine/advent

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.
