View inherited DEADLINEs in agenda

View inherited DEADLINEs in agenda

[Fabrizio Chiarello]

Hi all,

I have many tasks with a DEADLINE, and I wish to have their subtasks to
inherit such DEADLINE. To this aim, I set:

  (setq org-use-property-inheritance (quote ("DEADLINE")))

The problem is that the agenda only shows deadlines for the tasks that
define them (the parent tasks) and not for the subtasks. Is there a way
to view the inherited deadlines in the agenda?

Thanks in advance,
fc

is DEADLINE  a property that can be inherited?

would you please post an example file?

I don't think DEADLINE is a property at all.

In my org 7.7 manual, in section "7.2 Special properties", DEADLINE is
defined as a (special) property.

By the way, consider the following example:

* TODO parent
  DEADLINE: <2011-12-31 Sat>
** TODO child A
** TODO child B
   DEADLINE: <2011-11-30 Wed>
** TODO child C

In my workflow, to mark "parent" as DONE i have to complete "child" A,B
and C. And it would be nice to have child A and C inherit the DEADLINE
from the parent, and to show up in the agenda. Any idea?

I second this.

Tt would seem logical (to me at least) that the deadline should be
inherited. I.e. in order to finish the project in time one has to also
finish the subtasks in time.

Right now the following property is illogical from this point of view:

  (setq org-agenda-dim-blocked-tasks 'invisible)

since it hides the parent in the agenda even if the date is in the past!

Deadlines can currently *not* be inherited.  I would probably advice
against implementing this because of performance issues that would
result for the construction of the agenda.

Do you have any suggestion on how to implement the inherit of DEADLINE
from parent and how to show them in the agenda? At least for me, having
this feature working would repay the extra computation time required for
the construction of the agenda.

Thanks in advance,

Hi all,

Here's a thought: what about a function which scans a subtree of an
item that has a deadline and adds that same deadline to any
descendants that lack a deadline? It seems to me that this would, via
a one time user intervention, meet the OP's need, without the constant
overhead  about which Carsten is concerned.

It further occurred to me that invoked without arguments, it would
prompt the user for each item without deadline, with a prefix
argument, apply all the deadlines automatically, and, with a numeric
prefix n, automatically apply the alterations n-levels down.

Best,

Brian vdB

This is a good idea and very easy to do.
The only disadvantage is that any new entries you make
would not get the deadline.  Though, I think, one
could put a function into org-insert-heading-hook
to check for a deadline higher up in the tree and copy it.

I solved by adding the following block in the agenda:

;;;
(setq org-agenda-custom-commands
      '( ...
	(" " "Agenda"
	 ( ...
	  (todo "TODO|CANCELLED|NEXT|STARTED|WAITING|HOLD"
		((org-agenda-overriding-header "Inheritable DEADLINEs")
		 (org-agenda-skip-function 'fc/skip-non-inheritable-deadlines)))
))))
;;;

which shows the tasks without deadline that can inherit a deadline from
one of the parents. Then with the following keys I can set the deadline
of a task to that of the parent directly in the agenda.

;;;
(add-hook 'org-agenda-mode-hook
          (lambda ()
	    (org-defkey org-agenda-mode-map "D" 'fc/org-agenda-inherit-deadline))
          'append)

;;;

The rest of the functions are below

;;;
(defun fc/has-inheritable-deadline-p ()
  "Any task (without DEADLINE) that can inherit a DEADLINE"
  (let ((deadline (org-entry-get nil "DEADLINE"))
	(inheritable-deadline (org-entry-get-with-inheritance "DEADLINE")))

    (if (org-not-nil deadline)
	nil
      (if (org-not-nil inheritable-deadline)
	  t
	nil))))

(defun fc/skip-non-inheritable-deadlines ()
  "Skip tasks that cannot inherit a DEADLINE"
  (let* ((next-headline (save-excursion (or (outline-next-heading) (point-max)))))
    (if (fc/has-inheritable-deadline-p)
	nil
      next-headline)))

(defun fc/org-inherit-deadline ()
  "Inherit a DEADLINE."
  (interactive)
  (let* ((deadline (org-entry-get-with-inheritance "DEADLINE")))
    (if (and (org-not-nil deadline)
	     (y-or-n-p (format "Inherit DEADLINE: <%s>? " deadline)))
	(org-deadline nil (org-time-string-to-time deadline)))))

(defun fc/org-agenda-inherit-deadline (&optional arg)
  "Inherit a DEADLINE in agenda."
  (interactive "P")
  (let* ((marker (or (org-get-at-bol 'org-marker)
		     (org-agenda-error)))
	 (hdmarker (or (org-get-at-bol 'org-hd-marker)
		       marker))
	 (pos (marker-position marker))
	 newhead)
    (org-with-remote-undo (marker-buffer marker)
      (with-current-buffer (marker-buffer marker)
	(widen)
	(goto-char pos)
	(org-show-context 'agenda)
	(org-show-entry)
	(org-cycle-hide-drawers 'children)
	(fc/org-inherit-deadline)
	(setq newhead (org-get-heading)))
      (org-agenda-change-all-lines newhead hdmarker))))

Can you consider adding it to Worg/org-hacks.org?

If you want, just send me the .org content that I would

Hi All,

I had asked a similar question on StackOverflow a long time ago
(http://stackoverflow.com/questions/4872088/is-there-any-way-for-subtasks-to-inherit-deadlines-in-org-mode)
and one of the answers was useful to me - namely,
http://stackoverflow.com/a/8920418/137430.

Adding the answer here for sake of completion.

"How about a function for adding subtasks? This one adds a deadline to
the subtask if its parent has one:

(defun my-org-insert-sub-task ()
  (interactive)
  (let ((parent-deadline (org-get-deadline-time nil)))
    (org-goto-sibling)
    (org-insert-todo-subheading t)
    (when parent-deadline
      (org-deadline nil parent-deadline))))

Don't forget to bind it to a key:

(define-key org-mode-map (kbd "C-c s") 'my-org-insert-sub-task)"
