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

127 ;;; User Configurable Variables
130 "Options for exporting Org mode files to ASCII."
135 "Maximum width of exported text.
136 This number includes margin size, as set in
137 `org-ascii-global-margin'."
144 "Width of the left margin, in number of characters."
151 "Width of the inner margin, in number of characters.
152 Inner margin is applied between each headline."
159 "Width of margin used for quoting text, in characters.
160 This margin is applied on both sides of the text."
167 "Width of inline tasks, in number of characters.
168 This number ignores any margin."
175 "Number of blank lines inserted around headlines.
177 This variable can be set to a cons cell. In that case, its car
178 represents the number of blank lines present before headline
179 contents whereas its cdr reflects the number of blank lines after
180 contents.
182 A nil value replicates the number of blank lines found in the
183 original Org buffer at the same place."
194 "Additional indentation width for the first line in a paragraph.
195 If the value is an integer, indent the first line of each
196 paragraph by this number. If it is the symbol `auto' preserve
197 indentation from original document."
206 "Number of white lines between paragraphs.
207 If the value is an integer, add this number of blank lines
208 between contiguous paragraphs. If is it the symbol `auto', keep
209 the same number of blank lines as in the original document."
218 "The charset allowed to represent various elements and objects.
219 Possible values are:
220 `ascii' Only use plain ASCII characters
221 `latin1' Include Latin-1 characters
222 `utf-8' Use all UTF-8 characters"
234 "Characters for underlining headings in ASCII export.
236 Alist whose key is a symbol among `ascii', `latin1' and `utf-8'
237 and whose value is a list of characters.
239 For each supported charset, this variable associates a sequence
240 of underline characters. In a sequence, the characters will be
241 used in order for headlines level 1, 2, ... If no character is
242 available for a given level, the headline won't be underlined."
260 "Bullet characters for headlines converted to lists in ASCII export.
262 Alist whose key is a symbol among `ascii', `latin1' and `utf-8'
263 and whose value is a list of characters.
265 The first character is used for the first level considered as low
266 level, and so on. If there are more levels than characters given
267 here, the list will be repeated.
269 Note that this variable doesn't affect plain lists
270 representation."
286 "Non-nil means convert links to notes before the next headline.
287 When nil, the link will be exported in place. If the line
288 becomes long in this way, it will be wrapped."
295 "Non-nil means keep all vertical lines in ASCII tables.
296 When nil, vertical lines will be removed except for those needed
297 for column grouping."
304 "Non-nil means widen narrowed columns for export.
305 When nil, narrowed columns will look in ASCII export just like in
313 "Non-nil means table.el tables are turned into ascii-art.
315 It only makes sense when export charset is `utf-8'. It is nil by
316 default since it requires ascii-art-to-unicode.el package. You
317 can download it here:
319 http://gnuvola.org/software/j/aa2u/ascii-art-to-unicode.el."
326 "When non-nil, place caption string before the element.
327 Otherwise, place it right after it."
334 "Format string used for verbatim text and inline code."
342 "Function called to format a drawer in ASCII.
344 The function must accept three parameters:
346 CONTENTS the contents of the drawer.
347 WIDTH the text width within the drawer.
349 The function should return either the string to be exported or
350 nil to ignore the drawer.
352 The default value simply returns the value of CONTENTS."
359 'org-ascii-format-inlinetask-default
360 "Function called to format an inlinetask in ASCII.
362 The function must accept nine parameters:
363 TODO the todo keyword, as a string
364 TODO-TYPE the todo type, a symbol among `todo', `done' and nil.
365 PRIORITY the inlinetask priority, as a string
366 NAME the inlinetask name, as a string.
367 TAGS the inlinetask tags, as a list of strings.
368 CONTENTS the contents of the inlinetask, as a string.
369 WIDTH the width of the inlinetask, as a number.
370 INLINETASK the inlinetask itself.
371 INFO the info channel.
373 The function should return either the string to be exported or
374 nil to ignore the inline task."
381 \f
382 ;;; Internal Functions
384 ;; Internal functions fall into three categories.
386 ;; The first one is about text formatting. The core function is
387 ;; `org-ascii--current-text-width', which determines the current
388 ;; text width allowed to a given element. In other words, it helps
389 ;; keeping each line width within maximum text width defined in
390 ;; `org-ascii-text-width'. Once this information is known,
391 ;; `org-ascii--fill-string', `org-ascii--justify-string',
392 ;; `org-ascii--box-string' and `org-ascii--indent-string' can
393 ;; operate on a given output string.
395 ;; The second category contains functions handling elements listings,
396 ;; triggered by "#+TOC:" keyword. As such, `org-ascii--build-toc'
397 ;; returns a complete table of contents, `org-ascii--list-listings'
398 ;; returns a list of referenceable src-block elements, and
399 ;; `org-ascii--list-tables' does the same for table elements.
401 ;; The third category includes general helper functions.
402 ;; `org-ascii--build-title' creates the title for a given headline
403 ;; or inlinetask element. `org-ascii--build-caption' returns the
404 ;; caption string associated to a table or a src-block.
405 ;; `org-ascii--describe-links' creates notes about links for
406 ;; insertion at the end of a section. It uses
407 ;; `org-ascii--unique-links' to get the list of links to describe.
408 ;; Eventually, `org-ascii--translate' translates a string according
409 ;; to language and charset specification.
413 "Fill a string with specified text-width and return it.
415 S is the string being filled. TEXT-WIDTH is an integer
416 specifying maximum length of a line. INFO is the plist used as
417 a communication channel.
