extempore VS cakelisp

I've use a few "live coding" programming environments focused around audio programming where this is also the norm. Extempore ( https://github.com/digego/extempore, https://www.youtube.com/watch?v=yY1FSsUV-8c ) is a great example of this.

I grew up in the 70s with the term cybernetics from Norber Wiener, and I liked it before Gibson's Neuromancer in the 80s, so I guess I was inoculated before the pandemic use of the word. Cyber-Physical Systems (CPS) is a term being bandied about a bit now (reading Logical Foundations of Cyber-Physical Systems, and it is pretty cool [1]; Andrew Sorensen's Extempore as a CPS environment [2]). I also attended the first HOPE in 1994 in NYC and although the press abused the term cyber, it's still cool to me! But the Papa John's stuff was funny.

Extempore

I'm really fond of the idea of writing music like this.

From all available implementations of the idea, I probably like Extempore (https://github.com/digego/extempore) the most. Extempore provides a low-level C-like language (xtlang) which compiles into LLVM and can be meta-programmed from a variant of Scheme (TinyScheme I believe). This arrangement makes it possible to generate the code for the audio graph from Scheme, compile/optimize it via LLVM, then drive it in a live-coding fashion from Emacs. Best of both worlds (high and low).

My personal, much simpler attempt in this space is Cowbells (https://github.com/omkamra/cowbells) - with this one you can live-code FluidSynth (MIDI soundfonts) from Clojure + CIDER + Emacs, representing musical phrases either via Clojure data structures or an alternative text-based syntax (which is translated into the former by a compiler).

You might be interested in CakeLisp.

Cakelisp

"Cakelisp is a metaprogrammable, hot-reloadable, non-garbage-collected language ideal for high performance, iteratively-developed programs (especially games). It is a transpiler which generates C/C++ from an S-expression syntax. Cakelisp takes some inspiration from Lisp, but is not compatible and does not aspire to become 'a Lisp'."

This is a bug. Literally unusable.

Also look into Gamelisp's state machines which are an awesome way of modeling stateful in-game objects. Cakelisp is another cool language made specifically for gamedev.

I wrote a language primarily to make that sort of feature easy to create, via compile time code generation and execution. See Cakelisp.

cakelisp has no GC and is meant for games programming.

I've added a roadmap with items from my to-do list. I'm happy to receive ideas for features not on that list as well :).
