I've often heard this, but I don't really know of many people in the PL dev community who build their language in Racket. Also, I've taught a PL course and I tried to use Racket as a component, but students mostly just struggled with the LISP-y ness of it all, as they were primarily used to Java and Python. In all, I'm not really sure who Racket is for.

That was a great read from Cloudflare.

These days, I prefer Lean 4. Its macro system is inspired by racket and it has powerful types

I suppose, Racket is for CS grads / post-grads / researchers / professors. That is, not for those who just learn CS basics, but for those learnèd enough.

Students might use some simplified or customized languages produced with Racket. The syntax needs not be lispy; #lang algol60 is built in :)

Actually it's great for learning CS basics.

You list only academic positions. Has no popular software been written in it yet?

[djtango]

Naughty Dog used Racket and their own in house lisp (prior to that) to write their games.

Could be mistaken but IIRC Jak and Daxter was the first console game to have a fully streaming world and they achieved it using a technique inspired by their hot reloading dev setups

Arc was ported to Common Lisp last year, but before that was Racket.

And HN is written in Arc.

So does the website you're on count as popular software?

Six degrees of "Kevin..", I mean, Racket

Idris is bootstrapped on scheme if I recall correctly

[attila-lendvai]

it's bootstrapped off of GHC.

it was only using ChezScheme as an optimizing compiler backend.

(i created a PR to refactor their build system to reify the bootstrap process all the way down from GHC. it basically generalized the normal build workflow of Idris2 to be able to animate the entire bootstrap chain from GHC. sadly, it was pretty much ignored, and later abandoned: https://github.com/idris-lang/Idris2/pull/1990)

From the Idris 2 documentation:

    >> Can Idris 2 compile itself?
    > Yes, Idris 2 is implemented in Idris 2. By default, it targets Chez Scheme, 
    > so you can bootstrap from the generated Scheme code, as described in Section 
    > Getting Started.

Also, check this talk:

[attila-lendvai]

well, i wouldn't call that beeing bootstrapped.

in this case the generated scheme code is just a strange form of executable file that happens to need ChezScheme to be executed.

i.e. an ELF64 idris2 linux binary vs. an idris2.scm file that needs ChezScheme to come alive.

as for Idris2 implemented in Idris2: well, yes, that's true for the current version of Idris2. but the first version of Idris2 was written in Idris1. and the first version of Idris1 was written in Haskell.
