Hi,
I'm thinking I might like to try some programming to do things to the agenda
from an elisp function.
I tried 'apropos agenda' but I didn't really see the kind of thing I'm
looking for.
What I'm hoping is for some way to iterate over each item in the agenda, and
be able to access the content of the item in some structured way.
I think I've seen functions that can pull info like TODO state and priority
from the item under the cursor, so it's the iteration part that I'm really
interested in.

Any advice?
Cheers.
Fil

Hi Fil,

I just found the B f code to execute an arbitrary function on marked
entries in the agenda.  Maybe this will help?

This following code visits the marked entries and just displays the
heading for the task.

Mark multiple entries in the agenda with 'm' and then 'B f bh/test RET'
should display the heading of each marked task in the *Messages* buffer.

--8<---------------cut here---------------start------------->8---
(defun bh/test ()
  (interactive)
  (let* ((marker (or (org-get-at-bol 'org-marker)
		     (org-agenda-error)))
	 (buffer (marker-buffer marker))
	 (pos (marker-position marker)))
    (with-current-buffer buffer
      (if (org-mode-p)
	  (save-excursion
	    (goto-char pos)
	    (message "%s" (nth 4 (org-heading-components))))))))
--8<---------------cut here---------------end--------------->8---

Depending on what you want to do you can either act on marked entries or
create a custom agenda skip function that can visit the tasks as the
agenda is built.

HTH,
Bernt

Be sure to read the "Hacking" appendix in the org manual, in particular
"Using the property API" and "Using the mapping API".

Yup; I'd noticed those sections and noted them for future study.

In an agenda, try `C-u C-x =' to see all the text properties at point.
You can grab a lot of information from these properties.

Also useful can be

      (org-entry-properties marker)

Kind of slow for *many* entries, but perfectly good for a limited number...
