;;; Commentary:
;; Org-Babel support for evaluating Fomus source code.
;; For information on Fomus see http://fomus.sourceforge.net/
;;
;; This differs from most standard languages in that
;;
;; 1) there is no such thing as a "session" in fomus
;;
;; 2) we are generally only going to return results of type "file"
;;
;; 3) we are adding the "file" and "cmdline" header arguments
;;
;; 4) there are no variables (at least for now)
;;; Code:
(require 'ob)
(require 'ob-eval)
(defvar org-babel-default-header-args:fomus
'((:results . "file") (:exports . "results"))
"Default arguments to use when evaluating a fomus source block.")
(defun org-babel-expand-body:fomus (body params)
"Expand BODY according to PARAMS, return the expanded body."
(let ((vars (mapcar #'cdr (org-babel-get-header params :var))))
(mapc
(lambda (pair)
(let ((name (symbol-name (car pair)))
(value (cdr pair)))
(setq body
(replace-regexp-in-string
(concat "\$" (regexp-quote name))
(if (stringp value) value (format "%S" value))
body))))
vars)
body))
(defun org-babel-execute:fomus (body params)
"Execute a block of Fomus code with org-babel.
This function is called by `org-babel-execute-src-block'."
(let* ((result-params (cdr (assoc :result-params params)))
(out-file (cdr (assoc :file params)))
(cmdline (cdr (assoc :cmdline params)))
(cmd (or (cdr (assoc :cmd params)) "fomus"))
(in-file (org-babel-temp-file "fomus-" ".fms")))
(with-temp-file in-file
(insert (org-babel-expand-body:fomus body params)))
;; TMP: testing
;; (message (concat cmd
;; " " (org-babel-process-file-name in-file)
;; " " cmdline
;; " -o " (org-babel-process-file-name out-file)))
(org-babel-eval
(concat cmd
" " (org-babel-process-file-name in-file)
" " cmdline
" -o " (org-babel-process-file-name out-file)) "")
nil)) ;; signal that output has already been written to file
(defun org-babel-prep-session:fomus (session params)
"Return an error because Fomus does not support sessions."
(error "Fomus does not support sessions"))
(provide 'ob-fomus)
