|
||
;;; Commentary:
|
||
|
||
;; This file contains the code dealing with plain lists in Org-mode.
|
||
|
||
;; The core concept behind lists is their structure. A structure is
|
||
;; a snapshot of the list, in the shape of a data tree (see
|
||
;; `org-list-struct').
|
||
|
||
;; Once the list structure is stored, it is possible to make changes
|
||
;; on it that will be mirrored to the real list or to get information
|
||
;; about the list, using accessors and methods provided in the
|
||
;; library. Most of them require the use of one or two helper
|
||
;; functions, namely `org-list-parents-alist' and
|
||
;; `org-list-prevs-alist'.
|
||
|
||
;; Structure is eventually applied to the buffer with
|
||
;; `org-list-write-struct'. This function repairs (bullets,
|
||
;; indentation, checkboxes) the list in the process. It should be
|
||
;; called near the end of any function working on structures.
|
||
|
||
;; Thus, a function applying to lists should usually follow this
|
||
;; template:
|
||
|
||
;; 1. Verify point is in a list and grab item beginning (with the same
|
||
;; function `org-in-item-p'). If the function requires the cursor
|
||
;; to be at item's bullet, `org-at-item-p' is more selective. It
|
||
;; is also possible to move point to the closest item with
|
||
;; `org-list-search-backward', or `org-list-search-forward',
|
||
;; applied to the function `org-item-beginning-re'.
|
||
|
||
;; 2. Get list structure with `org-list-struct'.
|
||
|
||
;; 3. Compute one, or both, helper functions,
|
||
;; (`org-list-parents-alist', `org-list-prevs-alist') depending on
|
||
;; needed accessors.
|
||
|
||
;; 4. Proceed with the modifications, using methods and accessors.
|
||
|
||
;; 5. Verify and apply structure to buffer, using
|
||
;; `org-list-write-struct'.
|
||
|
||
;; 6. If changes made to the list might have modified check-boxes,
|
||
;; call `org-update-checkbox-count-maybe'.
|
||
|
||
;; Computing a structure can be a costly operation on huge lists (a
|
||
;; few thousand lines long). Thus, code should follow the rule:
|
||
;; "collect once, use many". As a corollary, it is usually a bad idea
|
||
;; to use directly an interactive function inside the code, as those,
|
||
;; being independent entities, read the whole list structure another
|
||
;; time.

a Alphabetically. Only the first line of item is checked.

t By date/time, either the first active time stamp in the entry, if
