27 ;;; Commentary:
29 ;; Org-Babel support for evaluating asymptote source code.
31 ;; This differs from most standard languages in that
33 ;; 1) there is no such thing as a "session" in asymptote
35 ;; 2) we are generally only going to return results of type "file"
37 ;; 3) we are adding the "file" and "cmdline" header arguments
39 ;; 4) there are no variables (at least for now)
41 ;;; Requirements:
43 ;; - The asymptote program :: http://asymptote.sourceforge.net/
45 ;; - asy-mode :: Major mode for editing asymptote files
47 ;;; Code:
48 (require 'org-babel)
50 (org-babel-add-interpreter "asymptote")
52 (add-to-list 'org-babel-tangle-langs '("asymptote" "asymptote"))
54 (defvar org-babel-default-header-args:asymptote '((:results . "file") (:exports . "results"))
55 "Default arguments to use when evaluating a asymptote source block.")
57 (defun org-babel-execute:asymptote (body params)
58 "Execute a block of Asymptote code with org-babel. This function is
59 called by `org-babel-execute-src-block'."
