;;; Commentary:
|
|
|
|
;; `ob-sclang' requires `sclang' from SuperCollider.
|
|
;; Usually SuperCollider dependencies for Emacs are at /usr/share/emacs/site-lisp/SuperCollider/
|
|
;; You can install SuperCollider following this article:
|
|
;; https://github.com/supercollider/supercollider#building-the-source-code
|
|
|
|
;; Usage:
|
|
|
|
;; Support to evaluate sclang Org-mode src block with function `sclang-eval-string'.
|
|
|
|
;; For example:
|
|
|
|
;; #+BEGIN_SRC sclang :results none
|
|
;; "Hello World".postln;
|
|
;; #+END_SRC
|
|
;;
|
|
;; *NOTE* Temporary output to org-babel result output is not supported.
|
|
;; Because `sclang-eval-string' will send output to Sclang Post Buffer.
|
|
;; And command line `sclang' execute will not automatically stop after finished execution.
|
|
;;
|
|
;; #+BEGIN_SRC sclang :results none
|
|
;; // modulate a sine frequency and a noise amplitude with another sine
|
|
;; // whose frequency depends on the horizontal mouse pointer position
|
|
;; {
|
|
;; var x = SinOsc.ar(MouseX.kr(1, 100));
|
|
;; SinOsc.ar(300 * x + 800, 0, 0.1)
|
|
;; +
|
|
;; PinkNoise.ar(0.1 * x + 0.1)
|
|
;; }.play;
|
|
;; #+END_SRC
