;;; Commentary:
|
||||
;;
|
||||
;; WARNING: This file is just a PROOF OF CONCEPT, not a supported part
|
||||
;; of Org-mode.
|
||||
;;
|
||||
;; This is an example implementation of TODO dependencies in Org-mode.
|
||||
;; It uses the new hooks in version 5.13 of Org-mode,
|
||||
;; `org-trigger-hook' and `org-blocker-hook'.
|
||||
;;
|
||||
;; It implements the following:
|
||||
;;
|
||||
;; Triggering
|
||||
;; ----------
|
||||
;;
|
||||
;; 1) If an entry contains a TRIGGER property that contains the string
|
||||
;; "chain-siblings(KEYWORD)", then switching that entry to DONE does
|
||||
;; do the following:
|
||||
;; - The sibling following this entry switched to todo-state KEYWORD.
|
||||
;; - The sibling also gets a TRIGGER property "chain-sibling(KEYWORD)",
|
||||
;; property, to make sure that, when *it* is DONE, the chain will
|
||||
;; continue.
|
||||
;;
|
||||
;; 2) If the TRIGGER property contains any other words like
|
||||
;; XYZ(KEYWORD), these are treated as entry id's with keywords. That
|
||||
;; means, Org-mode will search for an entry with the ID property XYZ
|
||||
;; and switch that entry to KEYWORD as well.
|
||||
;;
|
||||
;; Blocking
|
||||
;; --------
|
||||
;;
|
||||
;; 1) If an entry contains a BLOCKER property that contains the word
|
||||
;; "previous-sibling", the sibling above the current entry is
|
||||
;; checked when you try to mark it DONE. If it is still in a TODO
|
||||
;; state, the current state change is blocked.
|
||||
;;
|
||||
;; 2) If the BLOCKER property contains any other words, these are
|
||||
;; treated as entry id's. That means, Org-mode will search for an
|
||||
;; entry with the ID property exactly equal to this word. If any
|
||||
;; of these entries is not yet marked DONE, the current state change
|
||||
;; will be blocked.
|
||||
;;
|
||||
;; 3) Whenever a state change is blocked, an org-mark is pushed, so that
|
||||
;; you can find the offending entry with `C-c &'.
|
||||
;;
|
||||
;;; Example:
|
||||
;;
|
||||
;; When trying this example, make sure that the settings for TODO keywords
|
||||
;; have been activated, i.e. include the following line and press C-c C-c
|
||||
;; on the line before working with the example:
|
||||
;;
|
||||
;; #+TYP_TODO: TODO NEXT | DONE
|
||||
;;
|
||||
;; * TODO Win a million in Las Vegas
|
||||
;; The "third" TODO (see above) cannot become a TODO without this money.

||||

||||
;; :PROPERTIES:
|
||||
;; :ID: I-cannot-do-it-without-money
|
||||
;; :END:
|
||||
;;

||||

||||
;; :BLOCKER: I-cannot-do-it-without-money
|
||||
;; :END:
|
||||
;;
|
||||
;; ** This is the forth in this chain
|
||||
;; When this is DONE, we will also trigger entry XYZ-is-my-id
|
||||
;; :PROPERTIES:
|
||||
;; :TRIGGER: XYZ-is-my-id(TODO)
|
||||
;; :END:
