org-mode/lisp/ox-odt.el
Nicolas Goaziou 9dac00129d Update export back-ends wrt "file" link changes 
* lisp/ox-latex.el (org-latex-link):
* lisp/ox-html.el (org-html-link):  Do not expand absolute file names
  and do not try to fix hierarchy part, as it is already taken care of
  at the parser level.

* lisp/ox-md.el (org-md-link): Ditto.  Also fix absolute file names.

* lisp/ox-odt.el (org-odt-link):
* lisp/ox-man.el (org-man-link):
* lisp/ox-texinfo.el (org-texinfo-link):
* contrib/lisp/ox-groff.el (org-groff-link): Ditto.  Do not prepend
  scheme part to relative file names either.

* contrib/lisp/ox-deck.el (org-deck-link): Small refactoring.

INPUT-FMT-LIST is a list of INPUT-FMTs. OUTPUT-FMT-ALIST is an
alist where each element is of the form (OUTPUT-FMT
OUTPUT-FILE-EXTENSION EXTRA-OPTIONS).
The variable is interpreted as follows:
`org-odt-convert-process' can take any document that is in
INPUT-FMT-LIST and produce any document that is in the
OUTPUT-FMT-LIST. A document converted to OUTPUT-FMT will have
OUTPUT-FILE-EXTENSION as the file name extension. OUTPUT-FMT
serves dual purposes:
- It is used for populating completion candidates during
`org-odt-convert' commands.
- It is used as the value of \"%f\" specifier in
`org-odt-convert-process'.
EXTRA-OPTIONS is used as the value of \"%x\" specifier in
`org-odt-convert-process'.
DOCUMENT-CLASS is used to group a set of file formats in
INPUT-FMT-LIST in to a single class.
Note that this variable inherently captures how LibreOffice based
converters work. LibreOffice maps documents of various formats
to classes like Text, Web, Spreadsheet, Presentation etc and
allow document of a given class (irrespective of its source
format) to be converted to any of the export formats associated
with that class.
See default setting of this variable for an typical
configuration."

;; OpenDocument schema does not permit table to occur within a

;; One solution - the easiest and lightweight, in terms of
;; implementation - is to put the table in an indented text box
;; and make the text box part of the list-item. Unfortunately if
;; the table is big and spans multiple pages, the text box could
;; overflow. In this case, the following attribute will come
;; handy.
;; ,---- From OpenDocument-v1.1.pdf
;; | 15.27.28 Overflow behavior
;; |
;; | For text boxes contained within text document, the
;; | style:overflow-behavior property specifies the behavior of text
;; | boxes where the containing text does not fit into the text
;; | box.
;; |
;; | If the attribute's value is clip, the text that does not fit
;; | into the text box is not displayed.
;; |
;; | If the attribute value is auto-create-new-frame, a new frame
;; | will be created on the next page, with the same position and
;; | dimensions of the original frame.
;; |
;; | If the style:overflow-behavior property's value is
;; | auto-create-new-frame and the text box has a minimum width or
;; | height specified, then the text box will grow until the page
;; | bounds are reached before a new frame is created.
;; `----
;; Unfortunately, LibreOffice-3.4.6 doesn't honor
;; auto-create-new-frame property and always resorts to clipping
;; the text box. This results in table being truncated.
;; So we solve the problem the hard (and fun) way using list
;; continuations.
;; The problem only becomes more interesting if you take in to
;; account the following facts:
;;
;; - Description lists are simulated as plain lists.
;; - Low-level headlines can be listified.
;; - In Org-mode, a table can occur not only as a regular list
;; item, but also within description lists and low-level
;; headlines.
;; See `org-odt-translate-description-lists' and
;; `org-odt-translate-low-level-headlines' for how this is
