    Its successor, Extempore, which was mentioned by n3k5, is available for Windows, Mac, and Linux. https://extemporelang.github.io/ https://extemporelang.github.io/

  That project obviously has been dead for a long time, but its successor Extempore [0] seems to still be in somewhat active development. And btw. it runs on Linux, MacOS and Windows. [0] https://extemporelang.github.io/ https://extemporelang.github.io/

  Impromptu was pretty nice as a scripting env for Core Graphics (I sued it as such at some point). I also coordinated an effort to save it from being deleted from Wikipedia, along with Andrew Sorensen's "Study in Keith" video. Andrew who's also the author of Impromptu and Extempore, had gifted the recording of a live coding performance to Wikipedia, under a CC license. Some editors wanted to have it removed because it was "personal research". Go figure... Sanity prevailed thankfully. Edit: also, you should listen to "A study in Keith", it's a damn good piece. You can follow along as Andrew tweaks the grammar/Markov chains that make up the music, but it isn't necessary. The music starts at 1:56 (since the piece is written from scratch, there are a couple minutes of silent video while the author sets up the initial code). https://upload.wikimedia.org/wikipedia/commons/c/c5/Study_in_keith.ogv https://upload.wikimedia.org/wikipedia/commons/c/c5/Study_in...

  It is a Scheme REPL focussed on 3D graphics where the programming result is displayed as the background behind the code. Code can be made invisible with hotkey. It is a live coding environment for visuals. Used it for a project back in 2014 / 2015. It is really fun once you get to terms with LISP. Edit: typos

Another fun live coding environment is IBNIZ. http://viznut.fi/texts-en/ibniz.html http://viznut.fi/texts-en/ibniz.html

Live coding is great for beginners to discover and enjoy that programming is writing that makes things happen. I have had consistent success with design and communication students using LiveCodeLab [0] as the first step in our creative programming classes (ending with either Processing and Arduino or P5js/JavaScript) First they get the magic of it, summoning a cube with just ‘box’, animating it, playing with colors, then they ask ‘can we use that for…’ and we can go to step 2 [0] https://livecodelab.net/ https://livecodelab.net/

"screenshots and video" YouTube link is broken for me. Anyone managed to watch it? what am I doing wrong?

  I wasn't able to view it either. Another like I would like to view, the link to the Pixelache 2010 event in Helinski, was also broken for me: https://www.pixelache.ac/pages/pixelache-helsinki-2010 https://www.pixelache.ac/pages/pixelache-helsinki-2010

It mentions WebGL as one of its targets. Would it be possible to run Racket in the browser and have a fully browser-based live-coding environment?
- shadowgovt 6y ago
  It would have to be done carefully, but it doesn't strike me as strictly impossible. The challenge for a live coding browser environment is proper partitioning of the environment running the editor from the environment running code under development. The JavaScript environment in the browser is not multithreaded, so if the code under development hangs forever (and thanks to the halting problem, you can't guarantee it won't), you'll have a bad time because you can't access your tools to stop the code or modify the behavior. However, that doesn't mean it's impossible. There are multiple avenues I would suggest exploring that might ameliorate that problem (web workers, wasm, possibly iframes). As for the question of running racket in the browser in general, there are options. https://cs.brown.edu/~sk/Publications/Papers/Published/yk-whalesong-racket-browser/ https://cs.brown.edu/~sk/Publications/Papers/Published/yk-wh...

    > The JavaScript environment in the browser is not multithreaded Well, there's WebWorkers. They're a bit limited due to the whole message passing thing but still quite powerful. Aside from that: could whomever downvoted the person above me explain what's misinformative about their comment? https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers...

Cool! Take a look also at CEPL [0] an OpenGL environment for Common Lisp. Bit more low level, but you can have an OpenGL window open and make live changes in the code, just like anything else in Common Lisp. I can't imagine coding graphics any other way, and is a lot of fun that way too. [0] https://github.com/cbaggers/cepl https://github.com/cbaggers/cepl
- matheusmoreira 6y ago
  So how does it work? I imagine there are two concurrent threads: one receiving input from the programmer and another running the graphics and window event loop. How do these two communicate? I tried writing something similar as a teenager and the multithreading work quickly overwhelmed me. Perhaps there's a better approach?
  - ffwacom 6y ago
    I don't know about CEPL but when just using OpenGL you can simply redefine functions that are called in the main thread and they will execute there. You build up a lot of indirection to allow redefining things at run time. It's also a good idea to write some macros to send the forms to the main thread when working with graphics libs. This in clojure will eval the form once at the desired point in the program, it just queues up the forms and executes one every time it's called. The stuff below is racey but works. (def eval-points (atom {})) (defn eval-package [package] (binding [*ns* (:ns package)] (eval (:form package)))) (defmacro eval-point [name] (swap! eval-points assoc name []) `(do (let [fs# (~name @eval-points)] (when (peek fs#) (eval-package (peek fs#)) (swap! eval-points assoc ~name (pop fs#)))))) (defmacro package-form [& form] `{:ns ~*ns* :form '(do ~@form)}) (defmacro eval-at [name & form] `(swap! eval-points assoc ~name (conj (~name @eval-points) (package-form ~@form)))) So you would place (eval-point :foo) somewhere in the main loop so things like OpenGL calls are possible, then when evaling forms from the REPL you wrap them like: (eval-at :foo (blah 0.3 0.3 0.3)) You can easily do the same in common lisp.
