If not, see . ;;; Commentary: ;; ;; This library implements a generic export engine for Org, built on ;; its syntactical parser: Org Elements. ;; ;; Besides that parser, the generic exporter is made of three distinct ;; parts: ;; ;; - The communication channel consists in a property list, which is ;; created and updated during the process. Its use is to offer ;; every piece of information, would it be about initial environment ;; or contextual data, all in a single place. The exhaustive list ;; of properties is given in "The Communication Channel" section of ;; this file. ;; ;; - The transcoder walks the parse tree, ignores or treat as plain ;; text elements and objects according to export options, and ;; eventually calls back-end specific functions to do the real ;; transcoding, concatenating their return value along the way. ;; ;; - The filter system is activated at the very beginning and the very ;; end of the export process, and each time an element or an object ;; has been converted. It is the entry point to fine-tune standard ;; output from back-end transcoders. See "The Filter System" ;; section for more information. ;; ;; The core function is org-export-as'. It returns the transcoded ;; buffer as a string. ;; ;; An export back-end is defined with org-export-define-backend'. ;; This function can also support specific buffer keywords, OPTION ;; keyword's items and filters. Refer to function's documentation for ;; more information. ;; ;; If the new back-end shares most properties with another one, ;; org-export-define-derived-backend' can be used to simplify the ;; process. ;; ;; Any back-end can define its own variables. Among them, those ;; customizable should belong to the org-export-BACKEND' group. ;; ;; Tools for common tasks across back-ends are implemented in the ;; following part of the file. ;; ;; Then, a wrapper macro for asynchronous export, ;; org-export-async-start', along with tools to display results. are ;; given in the penultimate part. ;; ;; Eventually, a dispatcher (org-export-dispatch') for standard ;; back-ends is provided in the last one. ;;; Code: (eval-when-compile (require 'cl)) (require 'org-element) (require 'org-macro) (require 'ob-exp) (declare-function org-publish "ox-publish" (project &optional force async)) (declare-function org-publish-all "ox-publish" (&optional force async)) (declare-function org-publish-current-file "ox-publish" (&optional force async)) (declare-function org-publish-current-project "ox-publish" (&optional force async)) (defvar org-publish-project-alist) (defvar org-table-number-fraction) (defvar org-table-number-regexp) ;;; Internal Variables ;; ;; Among internal variables, the most important is ;; org-export-options-alist'.

A function associated to inner-template' is always applied. The latter, when defined, is to be called on every text not recognized as an element or an object. It must accept two arguments: the text string and the information channel. It is an appropriate place to protect special chars relative to the back-end. BODY can start with pre-defined keyword arguments. The following keywords are understood: :export-block String, or list of strings, representing block names that will not be parsed. This is used to specify blocks that will contain raw code specific to the back-end. These blocks still have to be handled by the relative export-block' type translator. :filters-alist Alist between filters and function, or list of functions, specific to the back-end. See org-export-filters-alist' for a list of all allowed filters. Filters defined here shouldn't make a back-end test, as it may prevent back-ends derived from this one to behave properly. :menu-entry Menu entry for the export dispatcher. It should be a list like: '(KEY DESCRIPTION-OR-ORDINAL ACTION-OR-MENU) where : KEY is a free character selecting the back-end. DESCRIPTION-OR-ORDINAL is either a string or a number. If it is a string, is will be used to name the back-end in its menu entry. If it is a number, the following menu will be displayed as a sub-menu of the back-end with the same KEY. Also, the number will be used to determine in which order such sub-menus will appear (lowest first). ACTION-OR-MENU is either a function or an alist. If it is an action, it will be called with four arguments (booleans): ASYNC, SUBTREEP, VISIBLE-ONLY and BODY-ONLY. See org-export-as' for further explanations on some of them. If it is an alist, associations should follow the pattern: '(KEY DESCRIPTION ACTION) where KEY, DESCRIPTION and ACTION are described above.
