Compiling ABC Blocks

In basic-mode the key sequence C-c C-c within an ABC block will compile the block. Exporting of all blocks and Org file contents is initialted with the sequence C-c C-e (standard Org-mode export keys).

Setup

Simply add abc to your list of babel languages (in your init file):

(org-babel-do-load-languages
  'org-babel-load-languages
  '(
    (emacs-lisp . t)
    (sh t)
    (org t)
    (abc t)))  <==== This is the line to add

Requirements

  • abcm2ps, a program that generates PostScript files from ABC Notation
  • abc-mode, an Emacs mode for editing ABC Notation
  • ps2pdf, a program to create PDF files from PostScript files

Issues

Issues should be reported to the Org-mode Mailing-list.
