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 modifying preferred charset
39 ;; through a buffer keyword or an option item, but, since the property
40 ;; will appear in communication channel nonetheless, it allows
41 ;; overriding `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.

150 "Options for exporting Org mode files to ASCII."
155 "Maximum width of exported text.
156 This number includes margin size, as set in
157 `org-ascii-global-margin'."
164 "Width of the left margin, in number of characters."
171 "Width of the inner margin, in number of characters.
172 Inner margin is applied between each headline."
179 "Width of margin used for quoting text, in characters.
180 This margin is applied on both sides of the text."
187 "Width of margin used for plain lists, in characters.
188 This margin applies to top level list only, not to its
189 sub-lists."
196 "Width of inline tasks, in number of characters.
197 This number ignores any margin."
204 "Number of blank lines inserted around headlines.
206 This variable can be set to a cons cell. In that case, its car
207 represents the number of blank lines present before headline
208 contents whereas its cdr reflects the number of blank lines after
209 contents.
211 A nil value replicates the number of blank lines found in the
212 original Org buffer at the same place."
223 "Additional indentation width for the first line in a paragraph.
224 If the value is an integer, indent the first line of each
225 paragraph by this width, unless it is located at the beginning of
226 a section, in which case indentation is removed from that line.
227 If it is the symbol `auto' preserve indentation from original
228 document."
237 "Number of white lines between paragraphs.
238 If the value is an integer, add this number of blank lines
239 between contiguous paragraphs. If is it the symbol `auto', keep
240 the same number of blank lines as in the original document."
249 "The charset allowed to represent various elements and objects.
250 Possible values are:
251 `ascii' Only use plain ASCII characters
252 `latin1' Include Latin-1 characters
253 `utf-8' Use all UTF-8 characters"
265 "Characters for underlining headings in ASCII export.
267 Alist whose key is a symbol among `ascii', `latin1' and `utf-8'
268 and whose value is a list of characters.
270 For each supported charset, this variable associates a sequence
271 of underline characters. In a sequence, the characters will be
272 used in order for headlines level 1, 2, ... If no character is
273 available for a given level, the headline won't be underlined."
291 "Bullet characters for headlines converted to lists in ASCII export.
293 Alist whose key is a symbol among `ascii', `latin1' and `utf-8'
294 and whose value is a list of characters.
296 The first character is used for the first level considered as low
297 level, and so on. If there are more levels than characters given
298 here, the list will be repeated.
300 Note that this variable doesn't affect plain lists
301 representation."
317 "Non-nil means convert links to notes before the next headline.
318 When nil, the link will be exported in place. If the line
319 becomes long in this way, it will be wrapped."
326 "Non-nil means keep all vertical lines in ASCII tables.
327 When nil, vertical lines will be removed except for those needed
328 for column grouping."
335 "Non-nil means widen narrowed columns for export.
336 When nil, narrowed columns will look in ASCII export just like in
345 It only makes sense when export charset is `utf-8'. It is nil by
347 available through, e.g., GNU ELPA."

372 The function must accept three parameters:
374 CONTENTS the contents of the drawer.
375 WIDTH the text width within the drawer.

393 PRIORITY the inlinetask priority, as a string
394 NAME the inlinetask name, as a string.

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

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