36 ;;; Define Back-End
37 ;;
38 ;; The following setting won't allow to modify preferred charset
39 ;; through a buffer keyword or an option item, but, since the property
40 ;; will appear in communication channel nonetheless, it allows to
41 ;; override `org-ascii-charset' variable on the fly by the ext-plist
42 ;; mechanism.
43 ;;
44 ;; We also install a filter for headlines and sections, in order to
45 ;; control blank lines separating them in output string.

152 "Options for exporting Org mode files to ASCII."
157 "Maximum width of exported text.
158 This number includes margin size, as set in
159 `org-ascii-global-margin'."
166 "Width of the left margin, in number of characters."
173 "Width of the inner margin, in number of characters.
174 Inner margin is applied between each headline."
181 "Width of margin used for quoting text, in characters.
182 This margin is applied on both sides of the text."
189 "Width of margin used for plain lists, in characters.
190 This margin applies to top level list only, not to its
191 sub-lists."
198 "Width of inline tasks, in number of characters.
199 This number ignores any margin."
206 "Number of blank lines inserted around headlines.
208 This variable can be set to a cons cell. In that case, its car
209 represents the number of blank lines present before headline
210 contents whereas its cdr reflects the number of blank lines after
211 contents.
213 A nil value replicates the number of blank lines found in the
214 original Org buffer at the same place."
225 "Additional indentation width for the first line in a paragraph.
226 If the value is an integer, indent the first line of each
227 paragraph by this width, unless it is located at the beginning of
228 a section, in which case indentation is removed from that line.
229 If it is the symbol `auto' preserve indentation from original
230 document."
239 "Number of white lines between paragraphs.
240 If the value is an integer, add this number of blank lines
241 between contiguous paragraphs. If is it the symbol `auto', keep
242 the same number of blank lines as in the original document."
251 "The charset allowed to represent various elements and objects.
252 Possible values are:
253 `ascii' Only use plain ASCII characters
254 `latin1' Include Latin-1 characters
255 `utf-8' Use all UTF-8 characters"
267 "Characters for underlining headings in ASCII export.
269 Alist whose key is a symbol among `ascii', `latin1' and `utf-8'
270 and whose value is a list of characters.
272 For each supported charset, this variable associates a sequence
273 of underline characters. In a sequence, the characters will be
274 used in order for headlines level 1, 2, ... If no character is
275 available for a given level, the headline won't be underlined."
293 "Bullet characters for headlines converted to lists in ASCII export.
295 Alist whose key is a symbol among `ascii', `latin1' and `utf-8'
296 and whose value is a list of characters.
298 The first character is used for the first level considered as low
299 level, and so on. If there are more levels than characters given
300 here, the list will be repeated.
302 Note that this variable doesn't affect plain lists
303 representation."
319 "Non-nil means convert links to notes before the next headline.
320 When nil, the link will be exported in place. If the line
321 becomes long in this way, it will be wrapped."
328 "Non-nil means keep all vertical lines in ASCII tables.
329 When nil, vertical lines will be removed except for those needed
330 for column grouping."
337 "Non-nil means widen narrowed columns for export.
338 When nil, narrowed columns will look in ASCII export just like in
346 "Non-nil means table.el tables are turned into ascii-art.
348 It only makes sense when export charset is `utf-8'. It is nil by
349 default since it requires ascii-art-to-unicode.el package. You
350 can download it here:
352 http://gnuvola.org/software/j/aa2u/ascii-art-to-unicode.el."

375 "Function called to format a drawer in ASCII.
377 The function must accept three parameters:
379 CONTENTS the contents of the drawer.
380 WIDTH the text width within the drawer.
382 The function should return either the string to be exported or
383 nil to ignore the drawer.

415 ;;; Internal Functions
417 ;; Internal functions fall into three categories.
419 ;; The first one is about text formatting. The core functions are
420 ;; `org-ascii--current-text-width' and
421 ;; `org-ascii--current-justification', which determine, respectively,
422 ;; the current text width allowed to a given element and its expected
423 ;; justification. Once this information is known,
424 ;; `org-ascii--fill-string', `org-ascii--justify-lines',
425 ;; `org-ascii--justify-element' `org-ascii--box-string' and
426 ;; `org-ascii--indent-string' can operate on a given output string.
427 ;; In particular, justification happens at the regular (i.e.,
428 ;; non-greater) element level, which means that when the exporting
429 ;; process reaches a container (e.g., a center block) content are
430 ;; already justified.
432 ;; The second category contains functions handling elements listings,
433 ;; triggered by "#+TOC:" keyword. As such, `org-ascii--build-toc'
434 ;; returns a complete table of contents, `org-ascii--list-listings'
435 ;; returns a list of referenceable src-block elements, and
436 ;; `org-ascii--list-tables' does the same for table elements.
438 ;; The third category includes general helper functions.
439 ;; `org-ascii--build-title' creates the title for a given headline
440 ;; or inlinetask element. `org-ascii--build-caption' returns the
441 ;; caption string associated to a table or a src-block.
442 ;; `org-ascii--describe-links' creates notes about links for
443 ;; insertion at the end of a section. It uses
444 ;; `org-ascii--unique-links' to get the list of links to describe.
445 ;; Eventually, `org-ascii--translate' translates a string according
446 ;; to language and charset specification.

457 among `left', `center', `right' or `full'. A nil value is
458 equivalent to `left'. For a justification that doesn't also fill
