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

CREATE-DECODE-MAP, MAXIMUM-SHORTEST, OVERLAY-PLIST,

UPDATE-TRANSLATION-FUNCTION, CONVERSION-KEYS and SIMPLE.
|
||
|
||
GUIDANCE specifies how a guidance string is shown in echo area.
|
||
If it is t, list of all possible translations for the current key is shown
|
||
with the currently selected translation being highlighted.
|
||
If it is an alist, the element has the form (CHAR . STRING). Each character
|
||
in the current key is searched in the list and the corresponding string is
|
||
shown.
|
||
If it is nil, the current key is shown.
|
||
|
||
DOCSTRING is the documentation string of this package.
|
||
|
||
TRANSLATION-KEYS specifies additional key bindings used while translation
|
||
region is active. It is an alist of single key character vs. corresponding
|
||
command to be called.
|
||
|
||
FORGET-LAST-SELECTION non-nil means a selected translation is not kept
|
||
for the future to translate the same key. If this flag is nil, a
|
||
translation selected for a key is remembered so that it can be the
|
||
first candidate when the same key is entered later.
|
||
|
||
DETERMINISTIC non-nil means the first candidate of translation is
|
||
selected automatically without allowing users to select another
|
||
translation for a key. In this case, unselected translations are of
|
||
no use for an interactive use of Quail but can be used by some other
|
||
programs. If this flag is non-nil, FORGET-LAST-SELECTION is also set
|
||
to t.
|
||
|
||
KBD-TRANSLATE non-nil means input characters are translated from a
|
||
user's keyboard layout to the standard keyboard layout. See the
|
||
documentation of `quail-keyboard-layout' and
|
||
`quail-keyboard-layout-standard' for more detail.
|
||
|
||
SHOW-LAYOUT non-nil means the `quail-help' command should show
|
||
the user's keyboard layout visually with translated characters.
|
||
If KBD-TRANSLATE is set, it is desirable to set also this flag unless
|
||
this package defines no translations for single character keys.
|
||
|
||
CREATE-DECODE-MAP non-nil means decode map is also created. A decode
|
||
map is an alist of translations and corresponding original keys.
|
||
Although this map is not used by Quail itself, it can be used by some
|
||
other programs. For instance, Vietnamese supporting needs this map to
|
||
convert Vietnamese text to VIQR format which uses only ASCII
|
||
characters to represent Vietnamese characters.
|
||
|
||
MAXIMUM-SHORTEST non-nil means break key sequence to get maximum
|
||
length of the shortest sequence. When we don't have a translation of
|
||
key \"..ABCD\" but have translations of \"..AB\" and \"CD..\", break
|
||
the key at \"..AB\" and start translation of \"CD..\". Hangul
|
||
packages, for instance, use this facility. If this flag is nil, we
|
||
break the key just at \"..ABC\" and start translation of \"D..\".
|
||
|
||
OVERLAY-PLIST if non-nil is a property list put on an overlay which
|
||
covers Quail translation region.
|
||
|
||
UPDATE-TRANSLATION-FUNCTION if non-nil is a function to call to update
|
||
the current translation region according to a new translation data. By
|
||
default, a translated text or a user's key sequence (if no translation
|
||
for it) is inserted.
|
||
|
||
CONVERSION-KEYS specifies additional key bindings used while
|
||
conversion region is active. It is an alist of single key character
|
||
vs. corresponding command to be called.
|
||
|
||
If SIMPLE is non-nil, then we do not alter the meanings of
|
||
commands such as C-f, C-b, C-n, C-p and TAB; they are treated as
|
||
non-Quail commands."
