Hi everyone,
if I have an org-file with this in it:
#+EMAIL: jkitchin@cmu.edu
is there an org lisp command to get the email address after I have opened
the file? I am looping through many files to generate a report, and would
like to do this in emacs-lisp. I had hoped org-entry-get would do it, but
it does not (it will retrieve it from #+PROPERTY: EMAIL jkitchin@cmu.edu).
Is it possible to define other keywords similar to that? E.g.
#+ANDREWID: jkitchin
and then to be able to read them from a lisp command (without writing the
parsing code myself)? something like (org-entry-get-keyword "ANDREWID").
I could not find anything like this in the property API (
http://orgmode.org/manual/Using-the-property-API.html) which is where i
thought it would be.
Thanks!
John

I'm interested in an answer to this as well...

Here's one way:
--8<---------------cut here---------------start------------->8---
(defun jk-org-kwds ()
(let* ((parse-tree (org-element-parse-buffer))
(keys (org-element-map parse-tree 'keyword (function identity))))
(mapcar (function (lambda (x) (cons (org-element-property :key x)
(org-element-property :value x)))) keys)))
--8<---------------cut here---------------end--------------->8---
This returns a list of (KEY. VALUE) pairs.
I'm sure there are other (better, cheaper) ways, but I'm going through
org-element.el, and having that hammer in hand, everything looks like
a nail to me :-)

I suggest the slightly more efficient variation:
(defun jk-org-kwds ()
(org-element-map (org-element-parse-buffer 'element) 'keyword
(lambda (keyword) (cons (org-element-property :key keyword)
(org-element-property :value keyword)))))
The optional argument `element' prevents `org-element-parse-buffer' from
diving too deep and `org-element-map' does the job of `mapcar'.
Regards,

If you mean file-level properties (ie not properties on headlines),
`org-export-get-environment' is one place to look. It runs
`org-export--get-inbuffer-options', which parses options at the top of
the file. I don't think it will read arbitrary properties, though...

Thanks for the great suggestions (Nick, Nick, and Eric)!
Here are the two functions that finally do what I wanted. I added the
second function to get a specific result.
#+RANDOM: tfjkdsla jfkdsa
#+BEGIN_SRC emacs-lisp :results value
; suggested by Nicolas Goaziou <n.goaziou@gmail.com>
(defun jk-org-kwds ()
(org-element-map (org-element-parse-buffer 'element) 'keyword
(lambda (keyword) (cons (org-element-property :key keyword)
(org-element-property :value keyword)))))
(defun jk-org-kwd (KEYWORD)
"get the value of a KEYWORD in the form of #+KEYWORD: value"
(cdr (assoc KEYWORD (jk-org-kwds))))
(jk-org-kwd "RANDOM")
#+END_SRC
#+RESULTS:
: tfjkdsla jfkdsa
A less orgish way I worked out last night after browsing through org.el is:
#+ANDREWID: jkitchin
#+BEGIN_SRC emacs-lisp :results value
(defun jk-get-file-keyword (KEYWORD)
"get the value from a line like this
#+OPTION: value
in a file."
(interactive)
(let ((case-fold-search t)
(re (format "^#\\+%s:[ \t]+\\([^\t\n]+\\)" KEYWORD)))
(if (not (save-excursion
(or (re-search-forward re nil t)
(re-search-backward re nil t))))
(error (format "No line containing #+%s: value found" KEYWORD)))
(match-string 1)))
(jk-get-file-keyword "ANDREWID")
#+END_SRC
#+RESULTS:
: jkitchin
This is pretty awesome!
John
