;;; Commentary:
;; 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
;;; Code:
(require 'org-babel)
(org-babel-add-interpreter "asymptote")
(add-to-list 'org-babel-tangle-langs '("asymptote" "asymptote"))
(defvar org-babel-default-header-args:asymptote '((:results . "file") (:exports . "results"))
"Default arguments to use when evaluating a asymptote source block.")
(defun org-babel-expand-body:asymptote (body params &optional processed-params) body)
(defun org-babel-execute:asymptote (body params)
"Execute a block of Asymptote code with org-babel. This function is
called by `org-babel-execute-src-block'."
(message "executing Asymptote source code block")
(let* ((result-params (split-string (or (cdr (assoc :results params)) "")))
(out-file (cdr (assoc :file params)))
(format (or (and out-file
(string-match ".+\\.\\(.+\\)" out-file)
(match-string 1 out-file))
"pdf"))
(cmdline (cdr (assoc :cmdline params)))
(in-file (make-temp-file "org-babel-asymptote"))
(cmd (concat "asy "
(if out-file
(concat "-globalwrite -f " format " -o " out-file)
"-V")
" " cmdline " " in-file)))
(with-temp-file in-file (insert body))
(message cmd) (shell-command cmd)
out-file))
(defun org-babel-prep-session:asymptote (session params)
(error "Asymptote does not support sessions"))
(provide 'org-babel-asymptote)
