Ludic: New framework for Python with seamless Htmx support
Generating `HTML` from lisps has poisoned any other approach for me, see for example https://www.neilvandyke.org/racket/html-writing/, https://reagent-project.github.io/, and https://edicl.github.io/cl-who/

Produce HTML from S-Expressions
Hiccup syntax for Clojure uses hash maps (curly braces) for attrs, e.g. `{:style {:background "red" :margin "1em"}`
See Reagent which uses Hiccup synta: https://reagent-project.github.io/

A History of Clojure (2020) [pdf]
* Single-Page App: shadow-cljs for the build concerns (https://github.com/thheller/shadow-cljs), Reagent with Re-frame for complex/large app (https://reagent-project.github.io and https://github.com/day8/re-frame). Even if we now prefer using HTMX (https://htmx.org) and server-side rendering (Hiccup way of manipulating HTML is just amazing, https://github.com/weavejester/hiccup).

Clojure is a product design tool
The API documentation lists the most commonly and rarely used parts before going into detail and there are many usage examples.
Reagent has a nice intro tutorial (classic todo-app): http://reagent-project.github.io and many other helpful tutorials and resources for beginners: https://cljdoc.org/d/reagent/reagent/1.2.0/doc/documentation...
However, since Reagent is still stuck with class-components for more complex behavior and relies on Hiccup, which is nice but has a performance cost compared to pure React, I am unsure about its future. Like some others in the Clojure community, I have moved to thin React wrappers like Helix and use Refx to integrate those with re-frame. It may be a bit confusing right now for beginners since there is no “golden path”.
Also, unfortunately, many smaller libraries are poorly documented and it seems like it is expected from the developer to dig into the source code to find out what’s going on.
What I found the most difficult as a beginner was how to setup a project in ClojureScript in the first place, like all the configuration in shadow-cljs, how it interacts with deps.edn, how it integrates with npm, the REPL, etc. But dev/build config has always been a weak spot for me, so it might be just that.
Overall, I still very much enjoy working with Clojure(Script), more than in any other language. Anyone who likes Lisps and functional programming should give it a try (and be sure to watch Rich Hickeys amazing talks!).

Building a website like it's 1999... in 2022
Clojure people have been doing this for a decade or so. It’s really so much better to work with. All started with Hiccup and when React came along you got Reagent and many more developments building on the idea.

React.dev
> But Reagent supports functional components as well, with hooks and all.
I addressed this already: while reagent is able to emit function components, there is a performance penalty to this.[1]
> I also very much like Hiccup, and so do many of us, because code is data and data is code, and Helix has decided not to support that.
Hiccup is convenient to write, but it is a constant run-time cost and a significant storage cost given that you have to store long series of constructors to cljs.core.PersistentVector in your bundle, have the JS runtime actually construct the vector, then pass it through a Hiccup interpreter to finally produce DOM nodes and throw away the persistent vector, only to repeat this entire process again on re-render.[2]
> Helix has decided not to support that.
That is simply not true. From the Helix documentation[2],
> If you want to use libraries like sablono, hicada or even hx hiccup parser, you can easily add that by creating a custom macro.
These are all Hiccup interpreters you can readily use.
IME there is very little difference between using the $ macro in Helix and writing Hiccup. I do not really miss Hiccup when I use Helix, and you still have data as code ;)
While this is from an unrelated project, there are benchmarks[3] done against Reagent that demonstrate the sheer overhead it has. In practice it is not a big problem if you rarely trigger a re-render, but otherwise it is a non-trivial cost, and if you want to use modern React features (like Suspense), there is a lot of r/as-element mingling going on, converting cases, etc. that simply make Reagent feel more tedious to use than Helix.
Also, the newer UIx2, which largely borrows from Helix, is "3.2x faster than Reagent" according to one of the contributors.[4]
I think it'd be worthwhile to benchmark all of these libraries against each other and record the data in one place. Maybe I'll get around to doing it this weekend :)

I Need to Grow Away from These Roots
Something fascinating about seeing a 'score' for generative music written out as a sort of specification like that.
There's enough detail there that you can take those instructions and reimplement your own version of it, and you'll end up with essentially the same 'piece of music', but certainly a different interpretation of it. Because while the score lays out some details precisely, it leaves other choices less clear. What does 'all inversions' really mean when enumerating chords? Does it include open, spread voicings? What durations should we choose from for our random waveforms? How short is 'short' when deciding to repeat? And of course, what wave synths should you use, and how should you modulate them?
All those are similar to the decisions a traditional instrumentalist makes when interpreting a sheet music score for performance - here, a generative music coder can follow this 'score' and produce a program that represents their own interpretation of the piece.
Coding it up in Sonic Pi (https://sonic-pi.net/) was a fun exercise, and I feel like I was able to produce something along the lines of what the composer intended. It carries the same kind of mood that the recording in the video has. But it's my own 'performance' of the work, if that makes sense (even if it's actually Sonic Pi 'performing' it at runtime...)
All of which got me thinking about the relationship more generally between specification, and implementation. Considering different programmers' implementations of algorithms as individual 'performances' of scores from the overall design - and then thinking about developers building elements of a larger system architecture as individual performers working to deliver their part of the performance as part of a band or orchestra. Some groups, maybe they're directed by a conductor-architect; others maybe are improvisers, riffing off one another and occasionally stepping up to deliver a solo. And some are maybe solid session performers, showing up and delivering strong but unflashy performances to a producer's specification.
So overall, a nice meditative coding exercise for a Sunday afternoon, and a shift in perspective. Thanks for sharing it.

Genuary 2024: Generative Art / Creative Coding Month
https://www.youtube.com/playlist?list=PLPYzvS8A_rTYEba_4SDvR...
- Sonic Pi is built on-top of SuperCollider, but it's MUCH easier to get started with making bleeps and bloops. Sam Aaron, who originally created Overtone (a Clojure front-end for SuperCollider) created Sonic Pi initially to teach kids computer programming and music, but now it's turning into a pretty nice live-coding setup. The language is basically a DSL extension of Ruby, and although it's very elegant, I feel like it's a little nerfed in terms of a full language when compared to SCLang, so I'm sticking with the latter for now. High recommend checking it out if you're new to making music or code. https://sonic-pi.net/
- This 'Intro To Live Coding' vid from Alex McLean is great. Gives a good overview of a few fun tools out there that I won't mention here for sake of time (check out Gibber and Hydra for web-based coding things. Gibber is really slick). Alex invented Tidal Cycles, which I feel is like god-tier in terms of power and conciseness. Maybe I'll tinker with Tidal someday, but I want to start with SC.

I really got traumatized
There is a programming language+IDE called SonicPI. It's designed to create music by writing code. You can install the program from the lin, then ask chatGPT to generate some sonic PI code that produces some nice melody. Then just copy the code and paste it into the sonicPI program, and run it by clicking the run button. Here's a conversation for example
