25 ;;; Commentary:
27 ;; This is the simplest of code blocks, where upon evaluation the
28 ;; contents of the code block are returned in a raw result.

31 (require 'ob)
33 (declare-function org-export-string "org-exp" (string fmt &optional dir))
35 (defvar org-babel-default-header-args:org
36 '((:results . "raw silent") (:exports . "results"))
37 "Default arguments for evaluating a org source block.")
39 (defvar org-babel-org-default-header
40 "#+TITLE: default empty header\n"
41 "Default header inserted during export of org blocks.")
43 (defun org-babel-expand-body:org (body params)
44 (dolist (var (mapcar #'cdr (org-babel-get-header params :var)))
45 (setq body (replace-regexp-in-string

47 nil 'literal)))
