[Orgmode] Re: How do you control sorting in org agenda?

[Emin.shopper Martinian.shopper]

It turned out my previous attempt at sorting didn't quite work, here
is an improved version of the hack for anyone else who wants to add
sub-priorities to control sorting of todo items:

(defun org-cmp-sub-priority (a b)
  """Compare the titles of string A and B

This function can be used in the org-agenda-cmp-user-defined variable
and org-agenda-sorting-strategy to compare the sort order of org entries.
It looks for something of the from TODO[<priority>]-<num> where <priority>
is one of #A, #B, #C indicating an org prioity and <num> is a sub-priority
which org doesn't know about but which controls the sorting order. For
example, I have TODO entries like

 TODO [#A]-01 foo
 TODO [#A]-02 bar
 TODO [#A]-03 baz

and use this function to make sure they get sorted properly in the
todo screen of org-agenda.

  """
  (let* ((aa (car (last (split-string (substring-no-properties a) "TODO .#."))))
        (bb (car (last (split-string (substring-no-properties b) "TODO .#."))))
        (use-a (string-match "^.?-[0-9]" aa))
        (use-b (string-match "^.?-[0-9]" bb))
        )
    (cond ((and use-a use-b)  ;; check if both aa and bb have a priority
           (cond ((string-lessp aa bb) -1) ;; if so, just compare strings
                 ((string-lessp bb aa) +1)
                 (t nil)))
          (use-a -1) ;; a has priority but not b
          (use-b +1) ;; b has priority but not a
          (t nil)) ;; nobody has priority so don't compare
  ))

(setq org-agenda-cmp-user-defined 'org-cmp-sub-priority)

(setq org-agenda-sorting-strategy
      '((agenda habit-down time-up priority-down category-keep)
        (todo   priority-down user-defined-up)
        (tags   priority-down category-keep)
        (search category-keep)))
