Feedback Welcome

Racket version 8.11.1 is now available from https://racket-lang.org/

Racket (https://racket-lang.org) has an IDE (DrRacket) which isn't EMACS. ARC (which powers hacker news) is (was?) written in Racket.

Nice! Repeating a comment I just made on HN: I signed up for RacketCon, will be joining remotely. I am looking forward to it a lot. Usually I use the Racket language perhaps for 10% of my personal projects, but I am currently writing a Racket AI book, so all things Racket are of current interest. Past RacketCons have been a lot of fun. I usually use Common Lisp, but Racket is batteries included Scheme, and more, and is a very pleasant language and ecosystem. Just in case you don’t have Racket installed: https://racket-lang.org/

I'd suggest Racket (https://racket-lang.org) which is a batteries-included language environment that includes scheme and has a lot of high-quality documentation.

Guile (https://www.gnu.org/software/guile/) isn't quite as learner-focused but is another great choice.

How did I get to the bottom of the page and not ONE person has recommended racket?

The Racket fork of CS supports Apple Silicon natively, and can be installed independently: https://github.com/racket/racket/blob/master/racket/src/ChezScheme/BUILDING Chez adds a few features (threads, ffi, ...) to R6RS; there is a useful combined index to TSPL4 and the CS User Guide at http://cisco.github.io/ChezScheme/csug9.5/csug_1.html

If you're using SICP in Scheme (or are you doing the JS version?) then you may want to look at How to Design Programs. It uses Racket which is a Scheme descendent so much of the language you've learned in SICP will work in it without issue. It also has a pretty good set of GUI and drawing capabilities you can find through the Racket docs page and will use some of with HTDP.

Based on the commit message [0], and the references to "user code" in this document, my guess is that user programs have or will have access, but it's not finalized enough to be documented.

That being said, I suppose if you're developing an internal API for a compiler/interpreter, your "users" could be other parts of the project rather than language users.

build with

    ./make.sh --without-gencgc --with-mark-region-gc (on x86-64/Linux and x86-64/macOS only at the moment).
