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', `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
54 ;; plain text.
55 ;;
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'.
63 ;;
64 ;; Some elements also have special properties whose value can hold
65 ;; objects themselves (e.g. an item tag or a headline name). Such
66 ;; values are called "secondary strings". Any object belongs to
67 ;; either an element or a secondary string.
68 ;;
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.
81 ;;
82 ;; At the lowest level, a `:parent' property is also attached to any
83 ;; string, as a text property.
84 ;;
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
90 ;; list.
91 ;; CONTENTS is a list of elements, objects or raw strings contained
92 ;; in the current element or object, when applicable.
93 ;;
94 ;; An Org buffer is a nested list of such elements and objects, whose
95 ;; type is `org-data' and properties is nil.
96 ;;
97 ;; The first part of this file defines Org syntax, while the second
98 ;; one provide accessors and setters functions.
99 ;;
100 ;; The next part implements a parser and an interpreter for each
101 ;; element and object type in Org syntax.
102 ;;
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'.
108 ;;
109 ;; The penultimate part is the cradle of an interpreter for the
110 ;; obtained parse tree: `org-element-interpret-data'.
111 ;;
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'.

274 In Org syntax, they can be written with optional square brackets

344 CAR is an element or object type containing objects and CDR is
345 a list of successors that will be called within an element or

348 For example, in a `radio-target' object, one can only find
349 entities, latex-fragments, subscript, superscript and text
350 markup.
352 This alist also applies to secondary string. For example, an

466 ;;; Greater elements
467 ;;
468 ;; For each greater element type, we define a parser and an
469 ;; interpreter.
470 ;;
471 ;; A parser returns the element or object as the list described above.
472 ;; Most of them accepts no argument. Though, exceptions exist. Hence
473 ;; every element containing a secondary string (see
474 ;; `org-element-secondary-value-alist') will accept an optional
475 ;; argument to toggle parsing of that secondary string. Moreover,
476 ;; `item' parser requires current list's structure as its first
477 ;; element.
478 ;;
479 ;; An interpreter accepts two arguments: the list representation of
480 ;; the element or object, and its contents. The latter may be nil,
481 ;; depending on the element or object considered. It returns the
482 ;; appropriate Org syntax, as a string.
483 ;;
484 ;; Parsing functions must follow the naming convention:
485 ;; org-element-TYPE-parser, where TYPE is greater element's type, as
486 ;; defined in `org-element-greater-elements'.
487 ;;
488 ;; Similarly, interpreting functions must follow the naming
489 ;; convention: org-element-TYPE-interpreter.
490 ;;
491 ;; With the exception of `headline' and `item' types, greater elements
492 ;; cannot contain other greater elements of their own type.
493 ;;
494 ;; Beside implementing a parser and an interpreter, adding a new
495 ;; greater element requires to tweak `org-element--current-element'.
496 ;; Moreover, the newly defined type must be added to both
497 ;; `org-element-all-elements' and `org-element-greater-elements'.

4051 `org-element-all-elements' and `org-element-all-objects' for an
4052 exhaustive list of such symbols. One can retrieve it with
4053 `org-element-type' function.
4055 PROPERTIES is the list of attributes attached to the element or
4056 object, as a plist. Although most of them are specific to the
4057 element or object type, all types share `:begin', `:end',
4058 `:post-blank' and `:parent' properties, which respectively
4059 refer to buffer position where the element or object starts,
4060 ends, the number of white spaces or blank lines after it, and
4061 the element or object containing it. Properties values can be
4062 obtained by using `org-element-property' function.
4064 CONTENTS is a list of elements, objects or raw strings
4065 contained in the current element or object, when applicable.
4066 One can access them with `org-element-contents' function.
4068 The Org buffer has `org-data' as type and nil as properties.
4069 `org-element-map' function can be used to find specific elements
4070 or objects within the parse tree.

4115 `org-element-all-objects' for a complete list of types). FUN is
4116 the function called on the matching element or object. It has to
4117 accept one argument: the element or object itself.
