;; Org-Babel support for evaluating asymptote source code.
|
|
;;
|
|
;; This differs from most standard languages in that
|
|
;;
|
|
;; 1) there is no such thing as a "session" in asymptote
|
|
;;
|
|
;; 2) we are generally only going to return results of type "file"
|
|
;;
|
|
;; 3) we are adding the "file" and "cmdline" header arguments, if file
|
|
;; is omitted then the -V option is passed to the asy command for
|
|
;; interactive viewing
|
|
;;
|
|
;; 4) there are no variables (at least for now)
|
|
|
|
;;; Requirements:

|
|
|
;; - The asymptote program :: http://asymptote.sourceforge.net/

;; - asy-mode :: Major mode for editing asymptote files
