;;; 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 an entry contains a TRIGGER property that contains the string
|
|
;; "chain-siblings-scheduled", then switching that entry to DONE does
|
|
;; the following actions, similarly to "chain-siblings(KEYWORD)":
|
|
;; - The sibling receives the same scheduled time as the entry
|
|
;; marked as DONE (or, in the case, in which there is no scheduled
|
|
;; time, the sibling does not get any either).
|
|
;; - The sibling also gets the same TRIGGER property
|
|
;; "chain-siblings-scheduled", so the chain can continue.
|
|
;;
|
|
;; 3) If the TRIGGER property contains the string
|
|
;; "chain-find-next(KEYWORD[,OPTIONS])", then switching that entry
|
|
;; to DONE do the following:
|
|
;; - All siblings are of the entry are collected into a temporary
|
|
;; list and then filtered and sorted according to OPTIONS
|
|
;; - The first sibling on the list is changed into KEYWORD state
|
|
;; - The sibling also gets the same TRIGGER property
|
|
;; "chain-find-next", so the chain can continue.
|
|
;;
|
|
;; OPTIONS should be a comma separated string without spaces, and
|
|
;; can contain following options:
|
|
;;
|
|
;; - from-top the candidate list is all of the siblings in
|
|
;; the current subtree
|
|
;;
|
|
;; - from-bottom candidate list are all siblings from bottom up
|
|
;;
|
|
;; - from-current candidate list are all siblings from current item
|
|
;; until end of subtree, then wrapped around from
|
|
;; first sibling
|
|
;;
|
|
;; - no-wrap candidate list are siblings from current one down
|
|
;;
|
|
;; - todo-only Only consider siblings that have a todo keyword
|
|
;; -
|
|
;; - todo-and-done-only
|
|
;; Same as above but also include done items.
|
|
;;
|
|
;; - priority-up sort by highest priority
|
|
;; - priority-down sort by lowest priority
|
|
;; - effort-up sort by highest effort
|
|
;; - effort-down sort by lowest effort
|
|
;;
|
|
;; Default OPTIONS are from-top
|
|
;;
|
|
;;
|
|
;; 4) 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
|
|
