Rhombus is what Racket should have been, back when it was the learning language at MIT, before it became Python. Had it been like this, maybe Python would have never gained traction within that community. The world would have been a very different place.
Rhombus' syntax is soooo beautiful. As a Racketeer, it's my dream language.
All the power of Racket... without a Lots of Insipid, Stupid Parenthesis.
Not that I don't like the parens, mind you, but Rhombus looks so much more... 2009. My only regret is that nobody will use Rhombus, except a few enthusiasts, for fun. In an AI age, new programming languages should really be LLM-first, sadly. But it makes me so happy that there are some people who still care about humans coding.
Racket was always one of my favorite Lisp / Scheme dialect, mainly because of its very rich ecosystem, you can make websites, GUIs a lot of things with very minimal effort, that and Dr Racket lets you see visually where import goes into code, and a bunch of other nice things.
Rhombus strikes to me as an interesting language in this ecosystem (which it is!) that not only gives you access to all those capabilities, but shows how powerful Racket can be for building programming languages!
That said I have not yet sat down to try it, but as they seem to be doing quick development with it, I just might have to.
I really want to like Racket? I really do, but I just never really enjoyed like I liked Python. And despite trying a bunch of other Lisps and liking them, something about Dr. Racket annoyed me. I'm not sure why.
It's "cool" and the ecosystem rules, and it's fast enough, I just never really found that I liked writing Racket or using Dr. Racket the same way I like writing Python so I never really reached for it when I was trying to do something. Indeed, from the first time I looked at Python I liked it. That was not the case with Javascript or Java or C or PHP? I don't know, I like Python and really want a practical Lisp that I can really sink my teeth into? So by all accounts I should love Racket. And yet, I don't.
That said, Rhombus looks really nice at first glance. This might be worth a sustained excursion to build something a bit more fun... I'm kind of excited about this!
Racket was my main language for personal stuff for years despite me never really liking it all that much and not able to put my finger on why. It's not even top 10 languages or top 5 lisps for me but it is just incredibly practical. I have zero passion for this language.
The way I use racket its main competitor is python. It's for when I want to accomplish something with heavy third party deps, and I have zero interest in writing the actual cool code I just need to make some libraries kiss and then use my tool. Not saying that's the case here but maybe racket just doesn't offer you much that python doesn't?
Sounds like you'd get more from just using one of the other lisps you liked, especially if there's a more specialized one that wouldn't be competing with a language you probably would prefer to use anyway. Like eg I have to deal with a lot of lua so I get my lisp rocks off with fennel.
This is something to think about... and you know, the other side of it is, "maybe I should play with Rhombus but also just spend some time playing more in Racket and choose to like it more?" lol - we can do that right? Choose to enjoy things?
One of the things I've really wanted to get into is writing some DSLs and Racket and Rhombus are supposed to be the tools you're supposed to reach for for that?
I don't know, the god's honest truth is that I don't write nearly as much code as I did 8 months ago lol, so maybe just diving into Racket and Rhombus for personal stuff would be fun and it doesn't have to something for work...
Really, the lisps I've really liked are Guile Scheme (ok not a lisp really but lispy enough and I liked it) and Clojure? But though I liked them I never had enough work in them to get really good. I do like Lispy languages in general though (since Emacs Lisp, which is glorious in it's own way), I just need the excuse to start playing with them more because they're fun.
You know what I've been really intrigued with over the years has been uLisp (which should be pronounced Micro Lisp) for microcontrollers (http://www.ulisp.com/), but a really cool project would be a DSL that spits out C for the STM32 boards I play with periodically for embedded stuff? I don't know, maybe after I get the cabin done... that'd be a really fun adventure and writing a DSL for that would make my life immensely easier...
Racket and Rhombus are nice for writing embedded DSLs, yeah. More generally, they're nice for writing macros. Scheme in general is nice for writing macros with its `syntax-case` and first-class notions of syntax objects, but Racket is /really/ nice with its `syntax-parse` and explicit notions of phase levels... If you are interested in learning, Greg Hendershott's "Fear of Macros" is often recommended as a good introduction. https://www.greghendershott.com/fear-of-macros/
I was reading through "Let Over Lambda" and kind of out of my depth because while I can mostly figure out what's going on I'm not using CL as a daily driver so the book just references functions and I'm like, "well I guess do-thing-nicely, does the thing nicely? Alright, good enough I suppose."
Maybe I should really give things another go with it. Thanks!
I experimented with Rhombus some time ago (most especially with Shplait). Is there much new with Shplait? Something I remember struggling with was trying to use racket libraries in Rhombus/Shplait
With AI becoming so predominant, I wonder if dynamically typed languages will lose favorability? Seems to me like a heavily documented, statically typed language is going to be ideal for AI programming. I'm wondering what role these flexible, coder-friendly, dynamically typed languages will play in the years to come.
The way the Rhombus / Racket community does libraries has to change. That whole package site has to change. Being a contributor on there exposes you to a steady stream of fraud garbage. There's nothing to promote the top libraries as the top libraries.
I agree that a ranking mechanism would be nice, but what do you mean by "fraud garbage"? I personally am not aware of any malicious package in the Racket ecosystem.

The entire Rhombus repo is all Racket:

Building languages was always one of selling points racket tried to push; the "Language-Oriented Programming Language" slogan and all.

Rhombus is easy to use and uniquely customizable.
