25 ;; This library implements an ASCII back-end for Org generic exporter.
26 ;; See Org manual for more information.

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.

126 ;;; User Configurable Variables
129 "Options for exporting Org mode files to ASCII."
134 "Maximum width of exported text.
135 This number includes margin size, as set in
136 `org-ascii-global-margin'."
143 "Width of the left margin, in number of characters."
150 "Width of the inner margin, in number of characters.
151 Inner margin is applied between each headline."
158 "Width of margin used for quoting text, in characters.
159 This margin is applied on both sides of the text."
166 "Width of inline tasks, in number of characters.
167 This number ignores any margin."
174 "Number of blank lines inserted around headlines.
176 This variable can be set to a cons cell. In that case, its car
177 represents the number of blank lines present before headline
178 contents whereas its cdr reflects the number of blank lines after
179 contents.
181 A nil value replicates the number of blank lines found in the
182 original Org buffer at the same place."
193 "Additional indentation width for the first line in a paragraph.
194 If the value is an integer, indent the first line of each
195 paragraph by this width, unless it is located at the beginning of
196 a section, in which case indentation is removed from that line.
197 If it is the symbol `auto' preserve indentation from original
198 document."
207 "Number of white lines between paragraphs.
208 If the value is an integer, add this number of blank lines
209 between contiguous paragraphs. If is it the symbol `auto', keep
210 the same number of blank lines as in the original document."
219 "The charset allowed to represent various elements and objects.
220 Possible values are:
221 `ascii' Only use plain ASCII characters
222 `latin1' Include Latin-1 characters
223 `utf-8' Use all UTF-8 characters"
235 "Characters for underlining headings in ASCII export.
237 Alist whose key is a symbol among `ascii', `latin1' and `utf-8'
238 and whose value is a list of characters.
240 For each supported charset, this variable associates a sequence
241 of underline characters. In a sequence, the characters will be
242 used in order for headlines level 1, 2, ... If no character is
243 available for a given level, the headline won't be underlined."
261 "Bullet characters for headlines converted to lists in ASCII export.
263 Alist whose key is a symbol among `ascii', `latin1' and `utf-8'
264 and whose value is a list of characters.
266 The first character is used for the first level considered as low
267 level, and so on. If there are more levels than characters given
268 here, the list will be repeated.
270 Note that this variable doesn't affect plain lists
271 representation."
287 "Non-nil means convert links to notes before the next headline.
288 When nil, the link will be exported in place. If the line
289 becomes long in this way, it will be wrapped."
296 "Non-nil means keep all vertical lines in ASCII tables.
297 When nil, vertical lines will be removed except for those needed
298 for column grouping."
305 "Non-nil means widen narrowed columns for export.
306 When nil, narrowed columns will look in ASCII export just like in
314 "Non-nil means table.el tables are turned into ascii-art.
316 It only makes sense when export charset is `utf-8'. It is nil by
317 default since it requires ascii-art-to-unicode.el package. You
318 can download it here:
320 http://gnuvola.org/software/j/aa2u/ascii-art-to-unicode.el."
327 "When non-nil, place caption string before the element.
328 Otherwise, place it right after it."
335 "Format string used for verbatim text and inline code."
343 "Function called to format a drawer in ASCII.
345 The function must accept three parameters:
347 CONTENTS the contents of the drawer.
348 WIDTH the text width within the drawer.
350 The function should return either the string to be exported or
351 nil to ignore the drawer.
353 The default value simply returns the value of CONTENTS."

361 "Function called to format an inlinetask in ASCII.
363 The function must accept nine parameters:
364 TODO the todo keyword, as a string
365 TODO-TYPE the todo type, a symbol among `todo', `done' and nil.
366 PRIORITY the inlinetask priority, as a string
367 NAME the inlinetask name, as a string.
368 TAGS the inlinetask tags, as a list of strings.
369 CONTENTS the contents of the inlinetask, as a string.
370 WIDTH the width of the inlinetask, as a number.

375 nil to ignore the inline task."

383 ;;; Internal Functions
385 ;; Internal functions fall into three categories.
387 ;; The first one is about text formatting. The core function is
388 ;; `org-ascii--current-text-width', which determines the current
389 ;; text width allowed to a given element. In other words, it helps
390 ;; keeping each line width within maximum text width defined in
391 ;; `org-ascii-text-width'. Once this information is known,
392 ;; `org-ascii--fill-string', `org-ascii--justify-string',
393 ;; `org-ascii--box-string' and `org-ascii--indent-string' can
394 ;; operate on a given output string.
396 ;; The second category contains functions handling elements listings,
397 ;; triggered by "#+TOC:" keyword. As such, `org-ascii--build-toc'
398 ;; returns a complete table of contents, `org-ascii--list-listings'
399 ;; returns a list of referenceable src-block elements, and
400 ;; `org-ascii--list-tables' does the same for table elements.
402 ;; The third category includes general helper functions.
403 ;; `org-ascii--build-title' creates the title for a given headline
404 ;; or inlinetask element. `org-ascii--build-caption' returns the
405 ;; caption string associated to a table or a src-block.
406 ;; `org-ascii--describe-links' creates notes about links for
407 ;; insertion at the end of a section. It uses
408 ;; `org-ascii--unique-links' to get the list of links to describe.
409 ;; Eventually, `org-ascii--translate' translates a string according
410 ;; to language and charset specification.
414 "Fill a string with specified text-width and return it.
