Subject: Filtering agenda by the "top" category
Date: Wed, 04 Apr 2012 15:38:55 -0500 [thread overview]
Message-ID: <email@example.com> (raw)
I discovered the < key in the agenda yesterday (by accident!), which filters
the Agenda down to entries having the same category.
However, I use both *categories* and *projects*. For example:
:OVERLAY: (face (:background "#fdfdeb"))
** PROJECT Foo
I use :CATEGORY: for my project here so it shows up in the leftmost column of
my agenda. I don't want every project displaying as just "Work". I use the
:OVERLAY: so that all Work items have the same background color, which is a
better way of seeing at a glance which *category* every item falls into.
What this means is that although I can use < to filter by *project*, I can't
filter down to the "Work" *category*. So that's what the code below does. I
bind it to >, since I wasn't using what that binding does.
Also, I found a bug: passing a prefix argument to < doesn't have any effect.
The code doesn't use that argument in any meaningful way.
(define-key org-agenda-mode-map ">" 'org-agenda-filter-by-top-category)
(defun org-find-top-category (&optional pos)
(with-current-buffer (if pos (marker-buffer pos) (current-buffer))
(if pos (goto-char pos))
;; Skip up to the topmost parent
(while (ignore-errors (outline-up-heading 1) t))
(nth 4 (org-heading-components))))))
(defvar org-agenda-filtered-by-top-category nil)
(defun org-agenda-filter-by-top-category (strip)
"Keep only those lines in the agenda buffer that have a specific category.
The category is that of the current line."
(setq org-agenda-filtered-by-top-category nil)
(let ((cat (org-find-top-category (org-get-at-bol 'org-hd-marker))))
(if cat (org-agenda-filter-top-category-apply cat)
(error "No top-level category at point")))))
(defun org-agenda-filter-top-category-apply (category)
"Set FILTER as the new agenda filter and apply it."
(while (not (eobp))
(let* ((pos (org-get-at-bol 'org-hd-marker))
(topcat (and pos (org-find-top-category pos))))
(if (and topcat (not (string= category topcat)))
(if (get-char-property (point) 'invisible)
(setq org-agenda-filtered-by-top-category t))
