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', `node-property', `quote-section' `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', `quote-section',
52 ;; `src-block', `table', `table-row' and `verse-block'. Among them,
53 ;; `paragraph' and `verse-block' types can contain Org objects and
56 ;; Objects are related to document's contents. Some of them are
57 ;; recursive. Associated types are of the following: `bold', `code',
58 ;; `entity', `export-snippet', `footnote-reference',
59 ;; `inline-babel-call', `inline-src-block', `italic',
60 ;; `latex-fragment', `line-break', `link', `macro', `radio-target',
61 ;; `statistics-cookie', `strike-through', `subscript', `superscript',
62 ;; `table-cell', `target', `timestamp', `underline' and `verbatim'.
64 ;; Some elements also have special properties whose value can hold
65 ;; objects themselves (i.e. an item tag or an headline name). Such
66 ;; values are called "secondary strings". Any object belongs to
67 ;; either an element or a secondary string.
69 ;; Notwithstanding affiliated keywords, each greater element, element
70 ;; and object has a fixed set of properties attached to it. Among
71 ;; them, four are shared by all types: `:begin' and `:end', which
72 ;; refer to the beginning and ending buffer positions of the
73 ;; considered element or object, `:post-blank', which holds the number
74 ;; of blank lines, or white spaces, at its end and `:parent' which
75 ;; refers to the element or object containing it. Greater elements,
76 ;; elements and objects containing objects will also have
77 ;; `:contents-begin' and `:contents-end' properties to delimit
78 ;; contents. Eventually, greater elements and elements accepting
79 ;; affiliated keywords will have a `:post-affiliated' property,
80 ;; referring to the buffer position after all such keywords.
82 ;; At the lowest level, a `:parent' property is also attached to any
83 ;; string, as a text property.
85 ;; Lisp-wise, an element or an object can be represented as a list.
86 ;; It follows the pattern (TYPE PROPERTIES CONTENTS), where:
87 ;; TYPE is a symbol describing the Org element or object.
88 ;; PROPERTIES is the property list attached to it. See docstring of
89 ;; appropriate parsing function to get an exhaustive
91 ;; CONTENTS is a list of elements, objects or raw strings contained
92 ;; in the current element or object, when applicable.
94 ;; An Org buffer is a nested list of such elements and objects, whose
95 ;; type is `org-data' and properties is nil.
97 ;; The first part of this file defines Org syntax, while the second
98 ;; one provide accessors and setters functions.
100 ;; The next part implements a parser and an interpreter for each
101 ;; element and object type in Org syntax.
103 ;; The following part creates a fully recursive buffer parser. It
104 ;; also provides a tool to map a function to elements or objects
105 ;; matching some criteria in the parse tree. Functions of interest
106 ;; are `org-element-parse-buffer', `org-element-map' and, to a lesser
107 ;; extent, `org-element-parse-secondary-string'.
109 ;; The penultimate part is the cradle of an interpreter for the
110 ;; obtained parse tree: `org-element-interpret-data'.
112 ;; The library ends by furnishing `org-element-at-point' function, and
113 ;; a way to give information about document structure around point
114 ;; with `org-element-context'.
