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

371 CREATE-DECODE-MAP, MAXIMUM-SHORTEST, OVERLAY-PLIST,
372 UPDATE-TRANSLATION-FUNCTION, CONVERSION-KEYS and SIMPLE.
374 GUIDANCE specifies how a guidance string is shown in echo area.
375 If it is t, list of all possible translations for the current key is shown
376 with the currently selected translation being highlighted.
377 If it is an alist, the element has the form (CHAR . STRING). Each character
378 in the current key is searched in the list and the corresponding string is
380 If it is nil, the current key is shown.
382 DOCSTRING is the documentation string of this package. The command
383 `describe-input-method' shows this string while replacing the form
384 \\=\\<VAR> in the string by the value of VAR. That value should be a
385 string. For instance, the form \\=\\<quail-translation-docstring> is
386 replaced by a description about how to select a translation from a
389 TRANSLATION-KEYS specifies additional key bindings used while translation
390 region is active. It is an alist of single key character vs. corresponding
391 command to be called.
393 FORGET-LAST-SELECTION non-nil means a selected translation is not kept
394 for the future to translate the same key. If this flag is nil, a
395 translation selected for a key is remembered so that it can be the
396 first candidate when the same key is entered later.
398 DETERMINISTIC non-nil means the first candidate of translation is
399 selected automatically without allowing users to select another
400 translation for a key. In this case, unselected translations are of
401 no use for an interactive use of Quail but can be used by some other
402 programs. If this flag is non-nil, FORGET-LAST-SELECTION is also set
405 KBD-TRANSLATE non-nil means input characters are translated from a
406 user's keyboard layout to the standard keyboard layout. See the
407 documentation of `quail-keyboard-layout' and
408 `quail-keyboard-layout-standard' for more detail.
410 SHOW-LAYOUT non-nil means the `quail-help' command should show
411 the user's keyboard layout visually with translated characters.
412 If KBD-TRANSLATE is set, it is desirable to set also this flag unless
413 this package defines no translations for single character keys.
415 CREATE-DECODE-MAP non-nil means decode map is also created. A decode
416 map is an alist of translations and corresponding original keys.
417 Although this map is not used by Quail itself, it can be used by some
418 other programs. For instance, Vietnamese supporting needs this map to
419 convert Vietnamese text to VIQR format which uses only ASCII
420 characters to represent Vietnamese characters.
422 MAXIMUM-SHORTEST non-nil means break key sequence to get maximum
423 length of the shortest sequence. When we don't have a translation of
424 key \"..ABCD\" but have translations of \"..AB\" and \"CD..\", break
425 the key at \"..AB\" and start translation of \"CD..\". Hangul
426 packages, for instance, use this facility. If this flag is nil, we
427 break the key just at \"..ABC\" and start translation of \"D..\".
429 OVERLAY-PLIST if non-nil is a property list put on an overlay which
430 covers Quail translation region.
432 UPDATE-TRANSLATION-FUNCTION if non-nil is a function to call to update
433 the current translation region according to a new translation data. By
434 default, a translated text or a user's key sequence (if no translation
437 CONVERSION-KEYS specifies additional key bindings used while
438 conversion region is active. It is an alist of single key character
439 vs. corresponding command to be called.
441 If SIMPLE is non-nil, then we do not alter the meanings of
442 commands such as C-f, C-b, C-n, C-p and TAB; they are treated as
