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 | |
271672fa BG |
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. | |
8223b1d2 BG |
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', | |
271672fa BG |
45 | ;; `item', `plain-list', `property-drawer', `quote-block', `section' |
46 | ;; and `special-block'. | |
8223b1d2 BG |
47 | ;; |
48 | ;; Other element types are: `babel-call', `clock', `comment', | |
271672fa BG |
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. | |
8223b1d2 BG |
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 | |
271672fa | 65 | ;; objects themselves (i.e. an item tag or a headline name). Such |
8223b1d2 BG |
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 | |
271672fa BG |
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. | |
8223b1d2 BG |
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'. | |

471 | ;; Most of them accepts no argument. Though, exceptions exist. Hence | |
472 | ;; every element containing a secondary string (see | |

474 | ;; argument to toggle parsing of that secondary string. Moreover, | |

476 | ;; element. | |
477 | ;; | |
478 | ;; An interpreter accepts two arguments: the list representation of | |
479 | ;; the element or object, and its contents. The latter may be nil, | |
480 | ;; depending on the element or object considered. It returns the | |
481 | ;; appropriate Org syntax, as a string. | |
482 | ;; | |
483 | ;; Parsing functions must follow the naming convention: | |
484 | ;; org-element-TYPE-parser, where TYPE is greater element's type, as | |
485 | ;; defined in `org-element-greater-elements'. | |
486 | ;; | |
487 | ;; Similarly, interpreting functions must follow the naming | |
488 | ;; convention: org-element-TYPE-interpreter. | |
489 | ;; | |
490 | ;; With the exception of `headline' and `item' types, greater elements | |
491 | ;; cannot contain other greater elements of their own type. | |
492 | ;; | |
493 | ;; Beside implementing a parser and an interpreter, adding a new | |
494 | ;; greater element requires to tweak `org-element--current-element'. | |

4044 | An element or an objects is represented as a list with the |
4045 | pattern (TYPE PROPERTIES CONTENTS), where : | |
4046 | ||
4047 | TYPE is a symbol describing the element or object. See | |
4048 | `org-element-all-elements' and `org-element-all-objects' for an | |
4049 | exhaustive list of such symbols. One can retrieve it with | |
4050 | `org-element-type' function. | |
4051 | ||
4052 | PROPERTIES is the list of attributes attached to the element or | |
4053 | object, as a plist. Although most of them are specific to the | |
4054 | element or object type, all types share `:begin', `:end', | |
4055 | `:post-blank' and `:parent' properties, which respectively | |
4056 | refer to buffer position where the element or object starts, | |
4057 | ends, the number of white spaces or blank lines after it, and | |
4058 | the element or object containing it. Properties values can be | |
4059 | obtained by using `org-element-property' function. | |
4060 | ||
4061 | CONTENTS is a list of elements, objects or raw strings | |

4063 | One can access them with `org-element-contents' function. | |

4109 | DATA is a parse tree, an element, an object, a string, or a list |

4111 | elements or objects types (see `org-element-all-elements' and | |

8223b1d2 BG |
4115 | |
4116 | When optional argument INFO is non-nil, it should be a plist | |

4124 | representing elements or objects types. `org-element-map' won't | |

4126 | list. Though, FUN can still be applied on them. | |

4138 | Assuming TREE is a variable containing an Org buffer parse tree, | |
4139 | the following example will return a flat list of all `src-block' | |
4140 | and `example-block' elements in it: | |
4141 | ||
4142 | \(org-element-map tree '(example-block src-block) 'identity) | |
4143 | ||
4144 | The following snippet will find the first headline with a level | |
4145 | of 1 and a \"phone\" tag, and will return its beginning position: | |
4146 | ||
271672fa | 4147 | \(org-element-map tree 'headline |

4148 | \(lambda (hl) |

4156 | ||
4157 | \(org-element-map tree 'plain-list 'identity nil nil 'plain-list) | |
4158 | ||
