** Why do I even?
|
||||
[[https://orgmode.org/][Org-mode]] makes [[http://literateprogramming.com/][literate programming]] easy via [[https://orgmode.org/worg/library-of-babel.html][Library of Babel]]. Il simply allows to mix text with executable /code blocks/ (which can also be extracted (/tangled/) into separate, executable files. The beauty of the Library of Babel implementation in org-mode lies in the fact that it supports many languages. I craved support for [[https://github.com/supercollider/supercollider][SuperCollider]] and craving became an itch when I needed to document a working pipeline alternating between executing sclang and shell scripts. I scratched an itch with this little module.

** How to install?
|
||||
First of all, you will need emacs (>=25) and SuperCollider (with emacs support) installed. Modern emacsen and Spacemacs come with bundled org-mode. At this point I am the sole user of this plugin and have just written it so I am not itching yet for MELPA or inclusion in the official org-mode repositories, so installation is manual. You can either drop [[file:ob-sclang.el]] somewhere in your Emacs' path or add its containing directory to ~load-path~ in =.init= file:
