;;; Commentary:

;; 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 '())

(defun org-babel-maxima-expand (body params)
  "Expand a block of Maxima code according to its header arguments."
  body)

(defun org-babel-execute:maxima (body params)
  "Execute a block of Maxima entries with org-babel.  This function is
called by `org-babel-execute-src-block'."
  (message "executing Maxima source code block")
  (let* ((result-params (split-string (or (cdr (assoc :results params)) "")))
	 (cmdline (cdr (assoc :cmdline params)))
	 (in-file (org-babel-temp-file "maxima-"))
	 (cmd (format "maxima --very-quiet -r 'batchload(%S)$' %s"
		      in-file cmdline)))
    (with-temp-file in-file (insert body))
    (message cmd)
    ((lambda (raw) ;; " | grep -v batch | grep -v 'replaced' | sed '/^$/d' "
       (delq nil
	     (mapcar (lambda (line)
		       (unless (or (string-match "batch" line)
				   (string-match "replaced" line)
				   (= 0 (length line)))
			 line))
		     (split-string raw))))
     (org-babel-eval cmd ""))))

(defun org-babel-prep-session:maxima (session params)
  (error "Maxima does not support sessions"))

(provide 'ob-maxima)
