;;; Commentary:
|
|
;;
|
|
;; This software provides EMACS org-babel export support for message
|
|
;; sequence charts. The mscgen utility is used for processing the
|
|
;; sequence definition, and must therefore be installed in the system.
|
|
;;
|
|
;; Mscgen is available and documented at
|
|
;; http://www.mcternan.me.uk/mscgen/index.html
|
|
;;
|
|
;; This code is directly inspired by Eric Schulte's ob-dot.el
|
|
;;
|
|
;; Example:
|
|
;;
|
|
;; #+begin_src mscgen :file example.png
|
|
;; msc {
|
|
;; A,B;
|
|
;; A -> B [ label = "send message" ];
|
|
;; A <- B [ label = "get answer" ];
|
|
;; }
|
|
;; #+end_src
|
|
;;
|
|
;; Header for alternative file type:
|
|
;;
|
|
;; #+begin_src mscgen :file ex2.svg :filetype svg
|
|
|
|
;; This differs from most standard languages in that
|
|
;;
|
|
;; 1) there is no such thing as a "session" in mscgen
|
|
;; 2) we are generally only going to return results of type "file"
|
|
;; 3) we are adding the "file" and "filetype" header arguments
|
|
;; 4) there are no variables
|
|
|
|
;;; Code:
|
|
(require 'ob)
|
|
|
|
(defvar org-babel-default-header-args:mscgen
|
|
'((:results . "file") (:exports . "results"))
