23 ;;; Commentary:
25 ;; This library implements a generic export engine for Org, built on
26 ;; its syntactical parser: Org Elements.
28 ;; Besides that parser, the generic exporter is made of three distinct
29 ;; parts:
31 ;; - The communication channel consists of a property list, which is
32 ;; created and updated during the process. Its use is to offer
33 ;; every piece of information, would it be about initial environment
34 ;; or contextual data, all in a single place.
36 ;; - The transcoder walks the parse tree, ignores or treat as plain
37 ;; text elements and objects according to export options, and
38 ;; eventually calls back-end specific functions to do the real
39 ;; transcoding, concatenating their return value along the way.
41 ;; - The filter system is activated at the very beginning and the very
42 ;; end of the export process, and each time an element or an object
43 ;; has been converted. It is the entry point to fine-tune standard
44 ;; output from back-end transcoders. See "The Filter System"
45 ;; section for more information.
47 ;; The core functions is `org-export-as'. It returns the transcoded
48 ;; buffer as a string. Its derivatives are `org-export-to-buffer' and
49 ;; `org-export-to-file'.
51 ;; An export back-end is defined with `org-export-define-backend'.
52 ;; This function can also support specific buffer keywords, OPTION
53 ;; keyword's items and filters. Refer to function's documentation for
54 ;; more information.
56 ;; If the new back-end shares most properties with another one,
57 ;; `org-export-define-derived-backend' can be used to simplify the
58 ;; process.
60 ;; Any back-end can define its own variables. Among them, those
61 ;; customizable should belong to the `org-export-BACKEND' group.
63 ;; Tools for common tasks across back-ends are implemented in the
64 ;; following part of the file.
66 ;; Eventually, a dispatcher (`org-export-dispatch') is provided in the
67 ;; last one.
69 ;; See <http://orgmode.org/worg/dev/org-export-reference.html> for
70 ;; more information.

665 10^-12 or 10^-tau a leading sign with digits or a word

667 terminated by almost any nonword/nondigit char.
668 x_{i^2} or x^(2-i) braces or parenthesis do grouping.
670 Still, ambiguity is possible. So when in doubt, use {} to enclose

892 ;; At the lowest level, a back-end is created with

895 ;; A named back-end can be registered with

899 ;; back-end from which slot values will be inherited by default.
900 ;; `org-export-derived-backend-p' can check if a given back-end is
901 ;; derived from a list of back-end names.

907 ;; At a higher level, `org-export-define-backend' is the standard way

909 ;; a registered back-end, `org-export-define-derived-backend' may be

1032 space, or nil. They must accept three arguments: the object or
1033 element itself, its contents or nil when it isn't recursive and
1034 the property list used as a communication channel.
1036 Contents, when not nil, are stripped from any global indentation
1037 \(although the relative one is preserved). They also always end
1038 with a single newline character.
1040 If, for a given type, no function is found, that element or
1041 object type will simply be ignored, along with any blank line or
1042 white space at its end. The same will happen if the function
1043 returns the nil value. If that function returns the empty
1044 string, the type will be ignored, but the blank lines or white
1045 spaces will be kept.
1047 In addition to element and object types, one function can be
1048 associated to the `template' (or `inner-template') symbol and
1049 another one to the `plain-text' symbol.
1051 The former returns the final transcoded string, and can be used
1052 to add a preamble and a postamble to document's body. It must
1053 accept two arguments: the transcoded string and the property list
1054 containing export options. A function associated to `template'
1055 will not be applied if export has option \"body-only\".
1056 A function associated to `inner-template' is always applied.
1058 The latter, when defined, is to be called on every text not
1059 recognized as an element or an object. It must accept two
1060 arguments: the text string and the information channel. It is an
1061 appropriate place to protect special chars relative to the
1062 back-end.
1064 BODY can start with pre-defined keyword arguments. The following
1065 keywords are understood:
1067 :export-block
1069 String, or list of strings, representing block names that
1070 will not be parsed. This is used to specify blocks that will
1071 contain raw code specific to the back-end. These blocks
1072 still have to be handled by the relative `export-block' type
1073 translator.
1075 :filters-alist
1077 Alist between filters and function, or list of functions,
1078 specific to the back-end. See `org-export-filters-alist' for
1079 a list of all allowed filters. Filters defined here
1080 shouldn't make a back-end test, as it may prevent back-ends
1081 derived from this one to behave properly.
1083 :menu-entry
1085 Menu entry for the export dispatcher. It should be a list
1086 like:
1088 '(KEY DESCRIPTION-OR-ORDINAL ACTION-OR-MENU)
1090 where :
1092 KEY is a free character selecting the back-end.
1094 DESCRIPTION-OR-ORDINAL is either a string or a number.
1096 If it is a string, is will be used to name the back-end in
1097 its menu entry. If it is a number, the following menu will
1098 be displayed as a sub-menu of the back-end with the same
1099 KEY. Also, the number will be used to determine in which
1100 order such sub-menus will appear (lowest first).
1102 ACTION-OR-MENU is either a function or an alist.
1104 If it is an action, it will be called with four
1105 arguments (booleans): ASYNC, SUBTREEP, VISIBLE-ONLY and
1106 BODY-ONLY. See `org-export-as' for further explanations on
1107 some of them.
1109 If it is an alist, associations should follow the
1110 pattern:
1112 '(KEY DESCRIPTION ACTION)

1241 ;; During export process, every function has access to a number of

1244 ;; 1. Environment options are collected once at the very beginning of
1245 ;; the process, out of the original buffer and configuration.
1246 ;; Collecting them is handled by `org-export-get-environment'
1247 ;; function.
1249 ;; Most environment options are defined through the
1250 ;; `org-export-options-alist' variable.
1252 ;; 2. Tree properties are extracted directly from the parsed tree,
1253 ;; just before export, by `org-export-collect-tree-properties'.
1255 ;;;; Environment Options
1257 ;; Environment options encompass all parameters defined outside the
1258 ;; scope of the parsed data. They come from five sources, in
1259 ;; increasing precedence order:
1261 ;; - Global variables,
1262 ;; - Buffer's attributes,
1263 ;; - Options keyword symbols,
1264 ;; - Buffer keywords,
1265 ;; - Subtree properties.
1267 ;; The central internal function with regards to environment options
1268 ;; is `org-export-get-environment'. It updates global variables with
1269 ;; "#+BIND:" keywords, then retrieve and prioritize properties from
1270 ;; the different sources.
1272 ;; The internal functions doing the retrieval are:
1273 ;; `org-export--get-global-options',
1274 ;; `org-export--get-buffer-attributes',
1275 ;; `org-export--parse-option-keyword',
1276 ;; `org-export--get-subtree-options' and
1277 ;; `org-export--get-inbuffer-options'

2178 ;; Filters allow end-users to tweak easily the transcoded output.
2179 ;; They are the functional counterpart of hooks, as every filter in
2180 ;; a set is applied to the return value of the previous one.
2182 ;; Every set is back-end agnostic. Although, a filter is always
2183 ;; called, in addition to the string it applies to, with the back-end
2184 ;; used as argument, so it's easy for the end-user to add back-end
2185 ;; specific filters in the set. The communication channel, as
2186 ;; a plist, is required as the third argument.
2188 ;; From the developer side, filters sets can be installed in the
2189 ;; process with the help of `org-export-define-backend', which
2190 ;; internally stores filters as an alist. Each association has a key
2191 ;; among the following symbols and a function or a list of functions
2192 ;; as value.
2194 ;; - `:filter-options' applies to the property list containing export
2195 ;; options. Unlike to other filters, functions in this list accept
2196 ;; two arguments instead of three: the property list containing
2197 ;; export options and the back-end. Users can set its value through
2198 ;; `org-export-filter-options-functions' variable.
2200 ;; - `:filter-parse-tree' applies directly to the complete parsed
2201 ;; tree. Users can set it through
2202 ;; `org-export-filter-parse-tree-functions' variable.
2204 ;; - `:filter-body' applies to the body of the output, before template
2205 ;; translator chimes in. Users can set it through
2206 ;; `org-export-filter-body-functions' variable.
2208 ;; - `:filter-final-output' applies to the final transcoded string.
2209 ;; Users can set it with `org-export-filter-final-output-functions'
2210 ;; variable.
2212 ;; - `:filter-plain-text' applies to any string not recognized as Org
2213 ;; syntax. `org-export-filter-plain-text-functions' allows users to
2214 ;; configure it.
2216 ;; - `:filter-TYPE' applies on the string returned after an element or
2217 ;; object of type TYPE has been transcoded. A user can modify
2218 ;; `org-export-filter-TYPE-functions' to install these filters.
2220 ;; All filters sets are applied with
2221 ;; `org-export-filter-apply-functions' function. Filters in a set are
2222 ;; applied in a LIFO fashion. It allows developers to be sure that
2223 ;; their filters will be applied first.
2225 ;; Filters properties are installed in communication channel with
2226 ;; `org-export-install-filters' function.
2228 ;; Eventually, two hooks (`org-export-before-processing-hook' and
2229 ;; `org-export-before-parsing-hook') are run at the beginning of the
2230 ;; export process and just before parsing to allow for heavy structure
2231 ;; modifications.

2677 ;; its derivative, `org-export-string-as'.
2678 ;; `org-export--copy-to-kill-ring-p' determines if output of these
2679 ;; function should be added to kill ring.
2681 ;; Note that `org-export-as' doesn't really parse the current buffer,
2682 ;; but a copy of it (with the same buffer-local variables and
2683 ;; visibility), where macros and include keywords are expanded and
2684 ;; Babel blocks are executed, if appropriate.
2685 ;; `org-export-with-buffer-copy' macro prepares that copy.
2687 ;; File inclusion is taken care of by
2688 ;; `org-export-expand-include-keyword' and
2689 ;; `org-export--prepare-file-contents'. Structure wise, including
2690 ;; a whole Org file in a buffer often makes little sense. For
2691 ;; example, if the file contains a headline and the include keyword
2692 ;; was within an item, the item should contain the headline. That's
2693 ;; why file inclusion should be done before any structure can be
2694 ;; associated to the file, that is before parsing.
2696 ;; `org-export-insert-default-template' is a command to insert
2697 ;; a default template (or a back-end specific template) at point or in
2698 ;; current subtree.
