i started working on a tree-sitter grammar for #sapf https://codeberg.org/pulu/sapf-ts

it really only does numbers and comments so far. improvements welcome 😄

ive fixed the zctl function in cross-platform #sapf, which is supposed to turn a ZRef into a control signal but was completely broken.

it is useful in OSC workflows, e.g.:

; store "/knob1" OSC data in the "cutoffknob" ZRef
0 ZR = cutoffknob
"127.0.0.1" 9901 "/knob1" \args [args head cutoffknob set] oscmap

; use it to control filter frequency
55 0 saw
(cutoffknob zctl 0 1 20 20000 linexp) 0.2 rlpf
0.2 *

ive moved the sapf.el repo to codeberg and also added some handy little functions to get help, clear the stack and clear the sapf process buffer 🥰

last year i added to cross-platform #sapf "oscmap", a preliminary Ref-based implementation of OSC input. this was simple to implement, but not very flexible.

ive now rewritten oscmap to use callback functions, similar to how SuperCollider OSCFuncs work. this is a lot more powerful and should allow far more diverse OSC handling logics :)

cross-platform #sapf is now a little more international as i fixed an issue that prevented non-ascii characters from being entered in the REPL.

it may not be "unicode-aware" exactly but the very simple parsing rules permit using unicode in identifiers. so now you can name your stuff with ääkköset, CJK, emoji and whatnot. go wild https://github.com/ahihi/sapf

#TIL about a new musical programming language called Sound As Pure Form #sapf and I'm wondering how I can interface it with @neauoire 's #Orca
