23 ;;; Commentary:
24 ;;
25 ;; Org syntax can be divided into three categories: "Greater
26 ;; elements", "Elements" and "Objects".
27 ;;
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.
31 ;;
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.
41 ;;
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'.
47 ;;
48 ;; Other element types are: `babel-call', `clock', `comment',
49 ;; `comment-block', `example-block', `export-block', `fixed-width',
50 ;; `horizontal-rule', `keyword', `latex-environment', `node-property',
51 ;; `paragraph', `planning', `quote-section', `src-block', `table',
52 ;; `table-row' and `verse-block'. Among them, `paragraph' and
53 ;; `verse-block' types can contain Org objects and plain text.
54 ;;
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'.
62 ;;
63 ;; Some elements also have special properties whose value can hold
64 ;; objects themselves (i.e. an item tag or an headline name). Such
65 ;; values are called "secondary strings". Any object belongs to
66 ;; either an element or a secondary string.
67 ;;
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 ;; and elements containing objects will also have `:contents-begin'
76 ;; and `:contents-end' properties to delimit contents.
77 ;;
78 ;; Lisp-wise, an element or an object can be represented as a list.
79 ;; It follows the pattern (TYPE PROPERTIES CONTENTS), where:
80 ;; TYPE is a symbol describing the Org element or object.
81 ;; PROPERTIES is the property list attached to it. See docstring of
82 ;; appropriate parsing function to get an exhaustive
83 ;; list.
84 ;; CONTENTS is a list of elements, objects or raw strings contained
85 ;; in the current element or object, when applicable.
86 ;;
87 ;; An Org buffer is a nested list of such elements and objects, whose
88 ;; type is `org-data' and properties is nil.
89 ;;
90 ;; The first part of this file defines Org syntax, while the second
91 ;; one provide accessors and setters functions.
92 ;;
93 ;; The next part implements a parser and an interpreter for each
94 ;; element and object type in Org syntax.
95 ;;
96 ;; The following part creates a fully recursive buffer parser. It
97 ;; also provides a tool to map a function to elements or objects
98 ;; matching some criteria in the parse tree. Functions of interest
99 ;; are `org-element-parse-buffer', `org-element-map' and, to a lesser
100 ;; extent, `org-element-parse-secondary-string'.
101 ;;
102 ;; The penultimate part is the cradle of an interpreter for the
103 ;; obtained parse tree: `org-element-interpret-data'.
104 ;;
105 ;; The library ends by furnishing `org-element-at-point' function, and
106 ;; a way to give information about document structure around point
107 ;; with `org-element-context'.

446 ;;; Greater elements
447 ;;
448 ;; For each greater element type, we define a parser and an
449 ;; interpreter.
450 ;;
451 ;; A parser returns the element or object as the list described above.
452 ;; Most of them accepts no argument. Though, exceptions exist. Hence
453 ;; every element containing a secondary string (see
454 ;; `org-element-secondary-value-alist') will accept an optional
455 ;; argument to toggle parsing of that secondary string. Moreover,
456 ;; `item' parser requires current list's structure as its first
457 ;; element.
458 ;;
459 ;; An interpreter accepts two arguments: the list representation of
460 ;; the element or object, and its contents. The latter may be nil,
461 ;; depending on the element or object considered. It returns the
462 ;; appropriate Org syntax, as a string.
463 ;;
464 ;; Parsing functions must follow the naming convention:
465 ;; org-element-TYPE-parser, where TYPE is greater element's type, as
466 ;; defined in `org-element-greater-elements'.
467 ;;
468 ;; Similarly, interpreting functions must follow the naming
469 ;; convention: org-element-TYPE-interpreter.
470 ;;
471 ;; With the exception of `headline' and `item' types, greater elements
472 ;; cannot contain other greater elements of their own type.
473 ;;
474 ;; Beside implementing a parser and an interpreter, adding a new
475 ;; greater element requires to tweak `org-element--current-element'.
476 ;; Moreover, the newly defined type must be added to both
