Okay, I got this to work in org-babel in a file foo.org
that has headlines like this:
* Foo.org :bar:
#+BEGIN_SRC emacs-lisp
(org-scan-tags 'agenda ;; Action
'(lambda (todo tags-list level) ;; Matcher
(progn
(setq org-cached-props nil)
(member "bar" tags-list))) ;; End
Matcher
org--matcher-tags-todo-only) ;; Todo-only
#+END_SRC
I removed the "staff" from the beginning of the function call, and changed
staff to "bar" I also removed the (or (and)) conditions :-)
Now, I need to see how to make this function search all agenda files - it
seems
to work only on the headlines in Foo.org
Thanks,
--Nate
