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

141 "When t, make TAB cycle visibility on plain list items.
142 Cycling plain lists works only when the cursor is on a plain list
143 item. When the cursor is on an outline heading, plain lists are
144 treated as text. This is the most stable way of handling this,
145 which is why it is the default.
147 When this is the symbol `integrate', then during cycling, plain
148 list items will *temporarily* be interpreted as outline headlines
149 with a level given by 1000+i where i is the indentation of the
150 bullet. This setting can lead to strange effects when switching
152 subtree decides what children should be listed. If that first
154 number, all true children and grand children of the outline
155 heading will be exposed in a children' view."
163 "Default bullet type installed when demoting an item.
164 This is an association list, for each bullet type, this alist will point
165 to the bullet that should be used when this item is demoted.
166 For example,
168 (setq org-list-demote-modify-bullet
171 will make
173 + Movies
174 + Silence of the Lambs
175 + My Cousin Vinny

183 - Silence of the Lambs

222 "A regular expression matching bullets that should have 2 spaces after them.
223 When nil, no bullet will have two spaces after them. When
224 a string, it will be used as a regular expression. When the
225 bullet type of a list is changed, the new bullet type will be
226 matched against this regexp. If it matches, there will be two
227 spaces instead of one after the bullet in each item of the list."
234 "Non-nil means an empty line ends all plain list levels.
235 Otherwise, two of them will be necessary."
242 "Non-nil means apply set of rules when acting on lists.
243 By default, automatic actions are taken when using
248 rules by setting them to nil. Valid rules are:
250 bullet when non-nil, cycling bullet do not allow lists at
251 column 0 to have * as a bullet and descriptions lists
252 to be numbered.
253 checkbox when non-nil, checkbox statistics is updated each time
254 you either insert a new checkbox or toggle a checkbox.
255 It also prevents from inserting a checkbox in a
256 description item.

276 and the item preceding the first item is the last one.
286 "Hook that is run whenever Org thinks checkbox statistics should be updated.
287 This hook runs even if checkbox rule in
288 `org-list-automatic-rules' does not apply, so it can be used to
289 implement alternative ways of collecting statistics
