Remove scheduled date when switch TODO states

Remove scheduled date when switch TODO states

[Nathaniel Flath]

[-- Attachment #1.1: Type: text/plain, Size: 260 bytes --]

Hello,

I have a todo state, PENDING, that I organize tasks that I cannot perform
immediately.  Is there a way to configure org-todoconfigure so that when a
task is switched to PENDING, if it has a scheduled date that date is
removed?

Thanks,
Nathaniel Flath

i'm not aware of any in-built way of doing this but org-schedule can be
called with org-trigger-hook to do the job but i still don't know
sufficient elisp to help with an implementation. :(

You could use the hook org-after-todo-state-change-hook. E.g.

--8<---------------cut here---------------start------------->8---
(defun my-org-pending-remove-deadline ()
  (when (equal (org-entry-get nil "TODO") "PENDING")
    (org-remove-timestamp-with-keyword org-deadline-string)))

(add-hook 'org-after-todo-state-change-hook 'my-org-pending-remove-deadline)
--8<---------------cut here---------------end--------------->8---

Best,
Matt

You can actually skip the `org-entry-get' as "The new state (a string
with a TODO keyword, or nil) is available in the Lisp variable
`state'"[1].

,----
| (defun my-org-pending-remove-deadline ()
|   (when (string= state "PENDING")
|     (org-remove-timestamp-with-keyword org-deadline-string)))
`----

Another solution: use `org-trigger-hook' and `org-schedule':

,----
| (defvar dmj/org-pending-keywords '("PENDING")
|   "List of keywords denoting pending state of an headline.")
| 
| (defun dmj/org-remove-schedule-when-pending (plist)
|   "Remove schedule when todo state changes to pending."
|   (let ((type (plist-get plist :type))
| 	(to (plist-get plist :to)))
|     (when (and (eq type 'todo-state-change)
| 	       (member to dmj/org-pending-keywords))
|       (org-schedule 'remove))))
`----
