Repeat tasks - mark done in a datetree

Question

In my org file, I have the following lines:

#+STARTUP: logdone logrepeat logreschedule logredeadline logrefile logdrawer
#+ARCHIVE: ::datetree/

When I mark a repeat task done, I want to:

1. Continue doing everything that is happening now (the task gets a new scheduled date, an entry is added in the :LOGBOOK: drawer, etc.) and additionally,

2. Make an entry in the datetree with DONE as the state for the task

How do I achieve this?

Answer 1

Does this do what you want?

(require 'org-datetree)
(defun my/log-to-datetree ()
  "Log the done item to the datetree."
  (when (equal org-state "DONE")
    (org-datetree-file-entry-under
     (format "* DONE %s" (nth 4 (org-heading-components)))
     (calendar-current-date))))

(add-hook 'org-after-todo-state-change-hook #'my/log-to-datetree t)
