Hi Thorsten,
I'm currently playing around with retrieving options, e.g. functions like:
#+begin_src elisp
(defun org-find-export-option (file option-name &optional backend)
"Find the OPTION of FILE."
(let* ((org-inhibit-startup t)
(visiting (find-buffer-visiting file))
(buffer (or visiting (find-file-noselect file)))
option)
(with-current-buffer buffer
(org-mode)
(setq option
(plist-get (org-export-get-environment backend) option-name)))
(unless visiting (kill-buffer buffer))
option))
(defun org-get-comma-separated-options-as-list (file option)
"Fetch OPTION from FILE as a list."
(split-string
(replace-regexp-in-string ", *" ","
(org-find-export-option file option 'blog))
"[,\n]"
t))
#+end_src
org-get-comma-separated-options-as-list description:
If you got options in MYFILE inthe form of
#+OPTION_NAME: a, b, two words, something else
#+OPTION_NAME: and, comma, at end,
#+OPTION_NAME: for, example
call
(org-get-comma-separated-options-as-list MYFILE :option-name)
(:option-name is the KEYWORD in the options alist, cf. ox.el)
you will get them now as
'( "a" "b" "two words" "something else" "and" "comma" "at end" "for"
"example").
"
The code is some copy and pasting of a current project, but should give
you some ideas.
org-find-export-option is also a slightly changed copy of
ox-publish.el's org-publish-find-title.
Best regards
Robert
