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. ;;; Code: (require 'org-macs) (org-assert-version) (require 'cl-lib) (require 'org-macs) (require 'org-compat) (require 'org-fold-core) (require 'org-footnote) (defvar org-M-RET-may-split-line) (defvar org-adapt-indentation) (defvar org-auto-align-tags) (defvar org-blank-before-new-entry) (defvar org-clock-string) (defvar org-closed-string) (defvar org-deadline-string) (defvar org-done-keywords) (defvar org-drawer-regexp) (defvar org-element-all-objects) (defvar org-inhibit-startup) (defvar org-loop-over-headlines-in-active-region) (defvar org-odd-levels-only) (defvar org-outline-regexp-bol) (defvar org-scheduled-string) (defvar org-todo-line-regexp) (defvar org-ts-regexp) (defvar org-ts-regexp-both) (declare-function org-at-heading-p "org" (&optional invisible-ok)) (declare-function org-back-to-heading "org" (&optional invisible-ok)) (declare-function org-before-first-heading-p "org" ()) (declare-function org-current-level "org" ()) (declare-function org-element-at-point "org-element" (&optional pom cached-only)) (declare-function org-element-context "org-element" (&optional element)) (declare-function org-element-interpret-data "org-element" (data)) (declare-function org-element-lineage "org-element-ast" (blob &optional types with-self)) (declare-function org-element-macro-interpreter "org-element" (macro ##)) (declare-function org-element-map "org-element" (data types fun &optional info first-match no-recursion with-affiliated)) (declare-function org-element-normalize-string "org-element" (s)) (declare-function org-element-parse-buffer "org-element" (&optional granularity visible-only keep-deferred)) (declare-function org-element-property "org-element-ast" (property node)) (declare-function org-element-begin "org-element" (node)) (declare-function org-element-end "org-element" (node)) (declare-function org-element-contents-begin "org-element" (node)) (declare-function org-element-contents-end "org-element" (node)) (declare-function org-element-post-affiliated "org-element" (node)) (declare-function org-element-post-blank "org-element" (node)) (declare-function org-element-parent "org-element-ast" (node)) (declare-function org-element-put-property "org-element-ast" (node property value)) (declare-function org-element-set "org-element-ast" (old new)) (declare-function org-element-type-p "org-element-ast" (node types)) (declare-function org-element-update-syntax "org-element" ()) (declare-function org-end-of-meta-data "org" (&optional full)) (declare-function org-entry-get "org" (pom property &optional inherit literal-nil)) (declare-function org-export-create-backend "ox" (&rest rest) t) (declare-function org-export-data-with-backend "ox" (data backend info)) (declare-function org-export-get-backend "ox" (name)) (declare-function org-export-get-environment "ox" (&optional backend subtreep ext-plist)) (declare-function org-export-get-next-element "ox" (blob info &optional n)) (declare-function org-export-with-backend "ox" (backend data &optional contents info)) (declare-function org-fix-tags-on-the-fly "org" ()) (declare-function org-get-todo-state "org" ()) (declare-function org-in-block-p "org" (names)) (declare-function org-inlinetask-goto-beginning "org-inlinetask" ()) (declare-function org-inlinetask-goto-end "org-inlinetask" ()) (declare-function org-inlinetask-in-task-p "org-inlinetask" ()) (declare-function org-inlinetask-outline-regexp "org-inlinetask" ()) (declare-function org-level-increment "org" ()) (declare-function org-mode "org" ()) (declare-function org-narrow-to-subtree "org" (&optional element)) (declare-function org-outline-level "org" ()) (declare-function org-previous-line-empty-p "org" ()) (declare-function org-reduced-level "org" (L)) (declare-function org-set-tags "org" (tags)) (declare-function org-fold-show-subtree "org-fold" ()) (declare-function org-fold-region "org-fold" (from to flag &optional spec)) (declare-function org-sort-remove-invisible "org" (S)) (declare-function org-time-string-to-seconds "org" (s)) (declare-function org-timer-hms-to-secs "org-timer" (hms)) (declare-function org-timer-item "org-timer" (&optional arg)) (declare-function outline-next-heading "outline" ()) (declare-function outline-previous-heading "outline" ()) ;;; Configuration variables (defgroup org-plain-lists nil "Options concerning plain lists in Org mode." :tag "Org Plain lists" :group 'org-structure) (defcustom org-cycle-include-plain-lists t "When t, make TAB cycle visibility on plain list items.
