|
;; Org-Babel support for evaluating maxima entries.
|
|
;;
|
|
;; This differs from most standard languages in that
|
|
;;
|
|
;; 1) there is no such thing as a "session" in maxima
|
|
;;
|
|
;; 2) we are generally only going to return output from maxima
|
|
;;
|
|
;; 3) we are adding the "cmdline" header argument
|
|
;;
|
|
;; 4) there are no variables
|
|
|
|
;;; Code:
|
|
(require 'ob)
|
|
|
|
(defvar org-babel-default-header-args:maxima '())
|
|
|
|
