Org provides a special hook to further limit items in agenda views:
tags-tree. Specify a custom function that tests inclusion of every
matched item in the view. This function can also skip as much as is
For a global condition applicable to agenda views, use the
org-agenda-skip-function-global variable. Org uses a global
org-agenda-skip-function for custom searching.
This example defines a function for a custom view showing TODO items with ‘waiting’ status. Manually this is a multi-step search process, but with a custom view, this can be automated as follows:
The custom function searches the subtree for the ‘waiting’ tag and
nil on match. Otherwise it gives the location from where
the search continues.
(defun my-skip-unless-waiting () "Skip trees that are not waiting" (let ((subtree-end (save-excursion (org-end-of-subtree t)))) (if (re-search-forward ":waiting:" subtree-end t) nil ; tag found, do not skip subtree-end))) ; tag not found, continue after end of subtree
To use this custom function in a custom agenda command:
(org-add-agenda-custom-command '("b" todo "PROJECT" ((org-agenda-skip-function 'my-skip-unless-waiting) (org-agenda-overriding-header "Projects waiting for something: "))))
Note that this also binds
org-agenda-overriding-header to a more
meaningful string suitable for the agenda view.
Search for entries with a limit set on levels for the custom search.
This is a general approach to creating custom searches in Org. To
include all levels, use ‘LEVEL>0’159. Then to selectively pick
the matched entries, use
org-agenda-skip-function, which also
accepts Lisp forms, such as
org-agenda-skip-subtree-if. For example:
Skip current entry if it has been scheduled.
Skip current entry if it has not been scheduled.
Skip current entry if it has a deadline.
Skip current entry if it has a deadline, or if it is scheduled.
Skip current entry if the TODO keyword is TODO or WAITING.
Skip current entry if the TODO keyword marks a DONE state.
Skip current entry if it has any timestamp, may also be deadline or scheduled.
Skip current entry if the regular expression matches in the entry.
Skip current entry unless the regular expression matches.
Same as above, but check and skip the entire subtree.
The following is an example of a search for ‘waiting’ without the special function:
(org-add-agenda-custom-command '("b" todo "PROJECT" ((org-agenda-skip-function '(org-agenda-skip-subtree-if 'regexp ":waiting:")) (org-agenda-overriding-header "Projects waiting for something: "))))
agenda* view is the same as
agenda except that it
only considers appointments, i.e., scheduled and deadline items that
have a time specification ‘[h]h:mm’ in their time-stamps.
Note that, for
org-odd-levels-only, a level number
corresponds to order in the hierarchy, not to the number of stars.
