;;; Commentary:

|
|
|
;;
|
|
|
|
|
;; This library implements both a Beamer back-end, derived from the
|
|
|
|
|
;; LaTeX one and a minor mode easing structure edition of the
|
|
|
|
|
;; document.
|
|
|
|
|
;;
|
|
|
|
|
;; Depending on the desired output format, three commands are provided
|
|
|
|
|
;; for export: `org-e-beamer-export-as-latex' (temporary buffer),
|
|
|
|
|
;; `org-e-beamer-export-to-latex' ("tex" file) and
|
|
|
|
|
;; `org-e-beamer-export-to-pdf' ("pdf" file).
|
|
|
|
|
;;
|
|
|
|
|
;; On top of buffer keywords supported by `e-latex' back-end (see
|
|
|
|
|
;; `org-e-latex-options-alist'), this back-end introduces the
|
|
|
|
|
;; following keywords: "BEAMER_THEME", "BEAMER_COLOR_THEME",
|
|
|
|
|
;; "BEAMER_FONT_THEME", "BEAMER_INNER_THEME" and "BEAMER_OUTER_THEME".
|
|
|
|
|
;; All accept options in square brackets.
|
|
|
|
|
;;
|
|
|
|
|
;; Moreover, headlines now fall into three categories: sectioning
|
|
|
|
|
;; elements, frames and blocks.
|
|
|
|
|
;;
|
|
|
|
|
;; - Like `e-latex' back-end sectioning elements are still set through
|
|
|
|
|
;; `org-e-latex-classes' variable.
|
|
|
|
|
;;
|
|
|
|
|
;; - Headlines become frames when their level is equal to
|
|
|
|
|
;; `org-e-beamer-frame-level' (or "H" value in the OPTIONS line).
|
|
|
|
|
;; Though, if an headline in the current tree has a "BEAMER_env"
|
|
|
|
|
;; (see below) property set to "frame", its level overrides the
|
|
|
|
|
;; variable.
|
|
|
|
|
;;
|
|
|
|
|
;; - All frames' children become block environments. Special block
|
|
|
|
|
;; types can be enforced by setting headline's "BEAMER_env" property
|
|
|
|
|
;; to an appropriate value (see `org-e-beamer-environments-default'
|
|
|
|
|
;; for supported value and `org-e-beamer-environments-extra' for
|
|
|
|
|
;; adding more).
|
|
|
|
|
;;
|
|
|
|
|
;; - As a special case, if the "BEAMER_env" property is set to either
|
2012-09-04 05:07:56 -04:00
|
|
|
|
;; "appendix", "note", "noteNH" or "againframe", the headline will
|
|
|
|
|
;; become, respectively, an appendix, a note (within frame or
|
|
|
|
|
;; between frame, depending on its level), a note with its title
|
|
|
|
|
;; ignored or an againframe command. In the latter case,
|
|
|
|
|
;; a "BEAMER_ref" property is mandatory in order to refer to the
|
|
|
|
|
;; frame being resumed, and contents are ignored.
|
2012-06-30 07:54:43 -04:00
|
|
|
|
;;
|
|
|
|
|
;; Also, an headline with an "ignoreheading" value will have its
|
|
|
|
|
;; contents only inserted in the output. This special value is
|
|
|
|
|
;; useful to have data between frames, or to properly close
|
|
|
|
|
;; a "column" environment.
|
|
|
|
|
;;
|
|
|
|
|
;; Along with "BEAMER_env", headlines also support "BEAMER_act" and
|
|
|
|
|
;; "BEAMER_opt" properties. The former is translated as an
|
|
|
|
|
;; overlay/action specification (or a default overlay specification
|
|
|
|
|
;; when enclosed within square brackets) whereas the latter specifies
|
|
|
|
|
;; options for the current frame ("fragile" option is added
|
|
|
|
|
;; automatically, though).
|
|
|
|
|
;;
|
|
|
|
|
;; Every plain list has support for `:overlay' attribute (through
|
|
|
|
|
;; ATTR_BEAMER affiliated keyword). Also, ordered (resp. description)
|
|
|
|
|
;; lists make use of `:template' (resp. `:long-text') attribute.
|
|
|
|
|
;;
|
|
|
|
|
;; Eventually, an export snippet with a value enclosed within angular
|
|
|
|
|
;; brackets put at the beginning of an element or object whose type is
|
|
|
|
|
;; among `bold', `item', `link', `radio-target' and `target' will
|
|
|
|
|
;; control its overlay specifications.
|
|
|
|
|
;;
|
|
|
|
|
;; On the minor mode side, `org-e-beamer-select-environment' (bound by
|
|
|
|
|
;; default to "C-c C-b") and `org-e-beamer-insert-options-template'
|
|
|
|
|
;; are the two entry points.

* contrib/lisp/org-export.el (org-export-registered-backends): New
variable.

new variable. Also redefine how sub-menus are defined.
(org-export-backend-filters, org-export-backend-menu,
org-export-backend-options, org-export-backend-translate-table): New
functions.
(org-export-get-environment, org-export--parse-option-keyword,
org-export--get-subtree-options, org-export--get-inbuffer-options,
org-export--get-global-options, org-export-install-filters,

(org-export-dispatch-ui): Display sub-menus according to new
definition.
(org-export-dispatch-menu-entries): Removed variable.
* contrib/lisp/org-e-beamer.el: Use new sub-menu definition.
(org-e-beamer--format-section, org-e-beamer-item,
org-e-beamer-keyword): Use `org-export-with-backend' instead of
relying on removed variables.

This patch gets rid of "invisible" variables, that is variables
defvar'ed within a macro.
