I struggled to get union of cases in an agenda block. I was able to work
from examples by Bernt Hansen at
http://doc.norang.ca/org-mode.html#CustomAgendaViewSetup
and
http://doc.norang.ca/org-mode.html#Projects,
and make the following small example, which may be useful to folks just
getting into Org-mode and Emacs, and want to be aware of how you can
combine cases into your agenda block. (Union as opposed to intersection,
OR vs AND.)
It should be straightforward to make various cases, or even finally get
familiar with the agenda filtering commands at
http://orgmode.org/manual/Filtering_002flimiting-agenda-items.html.
#+BEGIN_SRC emacs-lisp
(defun appts-nil-not-appt-next-headline ()
(let ((next-headline (save-excursion (outline-next-heading))))
(if (or ;; (string= "circus-act" (org-get-org-file))
(string= "circus-act" (org-get-category))
(member "appt" (org-get-tags-at))
(member "plans" (org-get-tags-at))
(member "social" (org-get-tags-at)))
nil
next-headline)))
#+END_SRC
(You may need this so that function org-add-agenda-custom-commands does
not create error.)
#+BEGIN_SRC emacs-lisp
(require 'org-agenda)
#+END_SRC
#+BEGIN_SRC emacs-lisp
(org-add-agenda-custom-command
'("c" "calendar"
agenda ""
((org-agenda-skip-function 'appts-nil-not-appt-next-headline)
)))
#+END_SRC
Please let me know if you see any changes I should make in my strategy
or code. (I've not made it a priority, but I think I shouldn't have the
three occurrences of `(member "<a tag>" (org-get-tags-at))'.)
Also, no telling when I'll get the chance to understand the examples at
