;;; 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
