Ask HN: What Are You Working On?
Currently working on a toolkit for writing custom interpreters [1], a language [2] on top of said toolkit and eventually a text editor [3] that uses them for scripting.

(Learn 'Scheme)
Sweet, I'll have to give that a go :)
Another option in browser land is lips[0], which exclusively targets a js backend.

All Web frontend lisp projects
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.

Extending a Language — Writing Powerful Macros in Scheme
Your example revealed a bug in my Scheme interpreter. This is an example that fails to match:
-
What other Scheme parser tricks do you know?
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:
-
How to list defined symbols?
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.

May I see some of your projects? :)

Async / Await in Scheme
(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?”

If you were hired to create a new distribution of Lisp, what would you include?
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.
