25 ;; Org syntax can be divided into three categories: "Greater
26 ;; elements", "Elements" and "Objects".
28 ;; Elements are related to the structure of the document. Indeed, all
29 ;; elements are a cover for the document: each position within belongs
30 ;; to at least one element.
32 ;; An element always starts and ends at the beginning of a line. With
33 ;; a few exceptions (`clock', `headline', `inlinetask', `item',
34 ;; `planning', `property-drawer', `node-property', `section' and
35 ;; `table-row' types), it can also accept a fixed set of keywords as
36 ;; attributes. Those are called "affiliated keywords" to distinguish
37 ;; them from other keywords, which are full-fledged elements. Almost
38 ;; all affiliated keywords are referenced in
39 ;; `org-element-affiliated-keywords'; the others are export attributes
40 ;; and start with "ATTR_" prefix.
42 ;; Element containing other elements (and only elements) are called
43 ;; greater elements. Concerned types are: `center-block', `drawer',
44 ;; `dynamic-block', `footnote-definition', `headline', `inlinetask',
45 ;; `item', `plain-list', `property-drawer', `quote-block', `section'
46 ;; and `special-block'.
48 ;; Other element types are: `babel-call', `clock', `comment',
49 ;; `comment-block', `diary-sexp', `example-block', `export-block',
50 ;; `fixed-width', `horizontal-rule', `keyword', `latex-environment',
51 ;; `node-property', `paragraph', `planning', `src-block', `table',
52 ;; `table-row' and `verse-block'. Among them, `paragraph' and
53 ;; `verse-block' types can contain Org objects and plain text.
55 ;; Objects are related to document's contents. Some of them are
56 ;; recursive. Associated types are of the following: `bold', `code',
57 ;; `entity', `export-snippet', `footnote-reference',
58 ;; `inline-babel-call', `inline-src-block', `italic',
59 ;; `latex-fragment', `line-break', `link', `macro', `radio-target',
60 ;; `statistics-cookie', `strike-through', `subscript', `superscript',
61 ;; `table-cell', `target', `timestamp', `underline' and `verbatim'.
63 ;; Some elements also have special properties whose value can hold
64 ;; objects themselves (e.g. an item tag or a headline name). Such
65 ;; values are called "secondary strings". Any object belongs to
66 ;; either an element or a secondary string.
68 ;; Notwithstanding affiliated keywords, each greater element, element
69 ;; and object has a fixed set of properties attached to it. Among
70 ;; them, four are shared by all types: `:begin' and `:end', which
71 ;; refer to the beginning and ending buffer positions of the
72 ;; considered element or object, `:post-blank', which holds the number
73 ;; of blank lines, or white spaces, at its end and `:parent' which
74 ;; refers to the element or object containing it. Greater elements,
75 ;; elements and objects containing objects will also have
76 ;; `:contents-begin' and `:contents-end' properties to delimit
77 ;; contents. Eventually, All elements have a `:post-affiliated'
78 ;; property referring to the buffer position after all affiliated
79 ;; keywords, if any, or to their beginning position otherwise.
81 ;; At the lowest level, a `:parent' property is also attached to any
82 ;; string, as a text property.
84 ;; Lisp-wise, an element or an object can be represented as a list.
85 ;; It follows the pattern (TYPE PROPERTIES CONTENTS), where:
86 ;; TYPE is a symbol describing the Org element or object.
87 ;; PROPERTIES is the property list attached to it. See docstring of
88 ;; appropriate parsing function to get an exhaustive
90 ;; CONTENTS is a list of elements, objects or raw strings contained
91 ;; in the current element or object, when applicable.
93 ;; An Org buffer is a nested list of such elements and objects, whose
94 ;; type is `org-data' and properties is nil.
96 ;; The first part of this file defines Org syntax, while the second
97 ;; one provide accessors and setters functions.
99 ;; The next part implements a parser and an interpreter for each
100 ;; element and object type in Org syntax.
102 ;; The following part creates a fully recursive buffer parser. It
103 ;; also provides a tool to map a function to elements or objects
104 ;; matching some criteria in the parse tree. Functions of interest
105 ;; are `org-element-parse-buffer', `org-element-map' and, to a lesser
106 ;; extent, `org-element-parse-secondary-string'.
108 ;; The penultimate part is the cradle of an interpreter for the
109 ;; obtained parse tree: `org-element-interpret-data'.
111 ;; The library ends by furnishing `org-element-at-point' function, and
112 ;; a way to give information about document structure around point
113 ;; with `org-element-context'. A cache mechanism is also provided for
125 ;;; Definitions And Rules
127 ;; Define elements, greater elements and specify recursive objects,
128 ;; along with the affiliated keywords recognized. Also set up
129 ;; restrictions on recursive objects combinations.

4718 ;; Internally, parsed elements are stored in an AVL tree,

4720 ;; a change happens to the buffer, a synchronization request is
4721 ;; registered in `org-element--cache-sync-requests' (see

4723 ;; are processed by `org-element--cache-sync'. Synchronization also
4724 ;; happens when an element is required from the cache. In this case,
4725 ;; the process stops as soon as the needed element is up-to-date.
4727 ;; A synchronization request can only apply on a synchronized part of
4728 ;; the cache. Therefore, the cache is updated at least to the
4729 ;; location where the new request applies. Thus, requests are ordered
4730 ;; from left to right and all elements starting before the first
4731 ;; request are correct. This property is used by functions like
4732 ;; `org-element--cache-find' to retrieve elements in the part of the
4733 ;; cache that can be trusted.
4735 ;; A request applies to every element, starting from its original
4736 ;; location (or key, see below). When a request is processed, it
4737 ;; moves forward and may collide the next one. In this case, both
4738 ;; requests are merged into a new one that starts from that element.
4739 ;; As a consequence, the whole synchronization complexity does not
4740 ;; depend on the number of pending requests, but on the number of
4741 ;; elements the very first request will be applied on.
4743 ;; Elements cannot be accessed through their beginning position, which
4744 ;; may or may not be up-to-date. Instead, each element in the tree is
