Is it possible to get property values from org file headers? For example, I have a file named with following content:

#+TITLE: Awesome File
#+AUTHOR: My Name
#+XYZ: xyz


How could one get title or XYZ? I want to get those values for some buffer-local variables.

You could use a slight modification of the answer to another question. After trying the full stuff in some org-file you can put into your init file and just use org-global-props in your org-file.

#+TITLE: Awesome File
#+AUTHOR: My Name
#+XYZ: xyz

  #+BEGIN_SRC emacs-lisp
;; Definition of `org-global-props' that could go into your init file:
(defun org-global-props (&optional property buffer)
  "Get the plists of global org properties of current buffer."
  (unless property (setq property "PROPERTY"))
  (with-current-buffer (or buffer (current-buffer))
    (org-element-map (org-element-parse-buffer) 'keyword (lambda (el) (when (string-match property (org-element-property :key el)) el)))))
;; Stuff for your org-file:
(mapcar (lambda (prop)
      (list (org-element-property :key prop)
        (org-element-property :value prop)))
    (org-global-props "\\(AUTHOR\\|TITLE\\|XYZ\\)"))

  | TITLE  | Awesome File |
  | AUTHOR | My Name      |
  | XYZ    | xyz          |

In order to get value of first property with key you can use following function.

(defun org-global-prop-value (key)
  "Get global org property KEY of current buffer."
  (org-element-property :value (car (org-global-props key))))

For example, (org-global-prop-value "author") returns My Name. Keep in mind, that key respects case sensitivity rules for search.

  • Nice, pretty almost what I wanted. Will do some modification and it would be perfect. BTW, thanks for the link. I saw that question, but didn't see that it's useful for my case as well :-P – d12frosted Apr 19 '16 at 11:04
  • But anyway, (org-element-property :value (car (org-global-props "AUTHOR"))) is fine enough. Thanks again. – d12frosted Apr 19 '16 at 11:08

    @d12frosted Yes, ... it is more like getting you on the right track. – Tobias Apr 19 '16 at 13:26
