31 ;; In Quail minor mode, you can input multilingual text easily. By
|
|
|
32 ;; defining a translation table (named Quail map) which maps ASCII key
|
|
|
33 ;; string to multilingual character or string, you can input any text
|
|
|
34 ;; from ASCII keyboard.
|
|
|
35 ;;
|
|
|
36 ;; We use words "translation" and "conversion" differently. The
|
|
|
37 ;; former is done by Quail package itself, the latter is the further
|
|
|
38 ;; process of converting a translated text to some more desirable
|
|
|
39 ;; text. For instance, Quail package for Japanese (`quail-jp')
|
|
|
40 ;; translates Roman text (transliteration of Japanese in Latin
|
|
|
41 ;; alphabets) to Hiragana text, which is then converted to
|
|
|
42 ;; Kanji-and-Kana mixed text or Katakana text by commands specified in
|
|
|
43 ;; CONVERSION-KEYS argument of the Quail package.

332 TITLE is a string to be displayed at mode-line to indicate this package.
|
|
|
333 Optional arguments are GUIDANCE, DOCSTRING, TRANLSATION-KEYS,
|
|
|
334 FORGET-LAST-SELECTION, DETERMINISTIC, KBD-TRANSLATE, SHOW-LAYOUT,
|
|
|
335 CREATE-DECODE-MAP, MAXIMUM-SHORTEST, OVERLAY-PLIST,
|
|
|
336 UPDATE-TRANSLATION-FUNCTION, and CONVERSION-KEYS.
|
|
|
337
|
|
|
338 GUIDANCE specifies how a guidance string is shown in echo area.
|
|
|
339 If it is t, list of all possible translations for the current key is shown
|
|
|
340 with the currently selected translation being highlighted.
|
|
|
341 If it is an alist, the element has the form (CHAR . STRING). Each character
|
|
|
342 in the current key is searched in the list and the corresponding string is
|
|
|
343 shown.
|
|
|
344 If it is nil, the current key is shown.
|
|
|
345
|
|
|
346 DOCSTRING is the documentation string of this package.
|
|
|
347
|
|
|
348 TRANSLATION-KEYS specifies additional key bindings used while translation
|
|
|
349 region is active. It is an alist of single key character vs. corresponding
|
|
|
350 command to be called.
|
|
|
351
|
|
|
352 FORGET-LAST-SELECTION non-nil means a selected translation is not kept
|
|
|
353 for the future to translate the same key. If this flag is nil, a
|
|
|
354 translation selected for a key is remembered so that it can be the
|
|
|
355 first candidate when the same key is entered later.
|
|
|
356
|
|
|
357 DETERMINISTIC non-nil means the first candidate of translation is
|
|
|
358 selected automatically without allowing users to select another
|
|
|
359 translation for a key. In this case, unselected translations are of
|
|
|
360 no use for an interactive use of Quail but can be used by some other
|
|
|
361 programs. If this flag is non-nil, FORGET-LAST-SELECTION is also set
|
|
|
362 to t.
|
|
|
363
|
|
|
364 KBD-TRANSLATE non-nil means input characters are translated from a
|
|
|
365 user's keyboard layout to the standard keyboard layout. See the
|
|
|
366 documentation of `quail-keyboard-layout' and
|
|
|
367 `quail-keyboard-layout-standard' for more detail.
|
|
|
368
|
|
|
369 SHOW-LAYOUT non-nil means the `quail-help' command should show
|
|
|
370 the user's keyboard layout visually with translated characters.
|
|
|
371 If KBD-TRANSLATE is set, it is desirable to set also this flag unless
|
|
|
372 this package defines no translations for single character keys.
|
|
|
373
|
|
|
374 CREATE-DECODE-MAP non-nil means decode map is also created. A decode
|
|
|
375 map is an alist of translations and corresponding original keys.
|
|
|
376 Although this map is not used by Quail itself, it can be used by some
|
|
|
377 other programs. For instance, Vietnamese supporting needs this map to
|
|
|
378 convert Vietnamese text to VIQR format which uses only ASCII
|
|
|
379 characters to represent Vietnamese characters.
|
|
|
380
|
|
|
381 MAXIMUM-SHORTEST non-nil means break key sequence to get maximum
|
|
|
382 length of the shortest sequence. When we don't have a translation of
|
|
|
383 key \"..ABCD\" but have translations of \"..AB\" and \"CD..\", break
|
|
|
384 the key at \"..AB\" and start translation of \"CD..\". Hangul
|
|
|
385 packages, for instance, use this facility. If this flag is nil, we
|
|
|
386 break the key just at \"..ABC\" and start translation of \"D..\".
|
|
|
387
|
|
|
388 OVERLAY-PLIST if non-nil is a property list put on an overlay which
|
|
|
389 covers Quail translation region.
|
|
|
390
|
|
|
391 UPDATE-TRANSLATION-FUNCTION if non-nil is a function to call to update
|
|
|
392 the current translation region accoding to a new translation data. By
|
|
|
393 default, a tranlated text or a user's key sequence (if no transltion
|
|
|
394 for it) is inserted.
|
|
|
395
|
|
|
396 CONVERSION-KEYS specifies additional key bindings used while
|
|
|
397 conversion region is active. It is an alist of single key character
|
|
|
398 vs. corresponding command to be called."
