;;; Commentary:

;; Convert cxterm dictionary (of TIT format) to quail-package.
;;
;; Usage (within Emacs):
;;      M-x titdic-convert<CR>CXTERM-DICTIONARY-NAME<CR>
;; Usage (from shell):
;;      % emacs -batch -l titdic-cnv -f batch-titdic-convert\
;;              [-dir DIR] [DIR | FILE] ...
;;
;; When you run titdic-convert within Emacs, you have a chance to
;; modify arguments of `quail-define-package' before saving the
;; converted file.  For instance, you are likely to modify TITLE,
;; DOCSTRING, and KEY-BINDINGS.

;; Cxterm dictionary file (*.tit) is a line-oriented text (English,
;; Chinese, Japanese, and Korean) file.  The whole file contains of
;; two parts, the definition part (`header' here after) followed by
;; the dictionary part (`body' here after).  All lines begin with
;; leading '#' are ignored.
;;
;; Each line in the header part has two fields, KEY and VALUE.  These
;; fields are separated by one or more white characters.
;;
;; Each line in the body part has two fields, KEYSEQ and TRANSLATIONS.
;; These fields are separated by one or more white characters.
;;
;; See the manual page of `tit2cit' of cxterm distribution for more
;; detail.
;;
;; Near the end of this file, we also have a few other tools to convert
;; miscellaneous dictionaries.

;;; Code:

(require 'quail)

;; List of values of key "ENCODE:" and the corresponding Emacs
;; coding-system and language environment name.

;; a docstring is automatically generated from the comments in the
;; dictionary.  The extra docstring in this alist is to add more
;; information.
;; The command describe-input-method shows the automatically generated
;; docstring, then an extra docstring while replacing the form \<VAR>
;; by the value of variable VAR.  For instance, the form
;; \<quail-translation-docstring> is replaced by a description about
;; how to select a translation from a list of candidates.

Pinyin base input method for Chinese charset GB2312 (`chinese-gb2312').

Pinyin is the standard roman transliteration method for Chinese.
Pinyin uses a sequence of Latin alphabetic characters for each Chinese
character.  The sequence is made by the combination of the initials
\(the beginning sounds) and finals (the ending sounds).

  initials: b p m f d t n l z c s zh ch sh r j q x g k h
  finals: a o e i er ai ei oa ou an en ang eng ong i ia iao ie iu ian in
          iang ing iong u ua uo uai ui uan un uan ueng yu yue yuan yun

  (Note: In the correct Pinyin writing, the sequence \"yu\" in the last
   four finals should be written by the character u-umlaut `\e$A(9\e(B'.)

With this input method, you enter a Chinese character by first
entering its pinyin spelling.

\\<quail-translation-docstring>

For instance, to input \e$ADc\e(B, you type \"n i C-n 3\".  The first \"n i\"
is a Pinyin, \"C-n\" selects the next group of candidates (each group
contains at most 10 characters), \"3\" select the third character in
that group.

This input method supports only Han characters.  The related input
method `chinese-py-punct' is the combination of this method and
`chinese-punct'; it supports both Han characters and punctuation
characters.

For double-width GB2312 characters corresponding to ASCII, use the
input method `chinese-qj'.

The correct Pinyin system specifies tones by diacritical marks, but
this input method doesn't use them, which results in easy (you don't
have to know the exact tones), but verbose (many characters are assigned
to the same key sequence) input.  You may also want to try the input
method `chinese-tonepy' with which you must specify tones by digits
\(1..5)."))

Pinyin base input method for Chinese GB2312 characters (`chinese-gb2312').

Pinyin is the standard roman transliteration method for Chinese.
For the details of Pinyin system, see the documentation of the input
method `chinese-py'.

Unlike the standard spelling of Pinyin, in this input method all
initials and finals are assigned to single keys (see the above table).
For instance, the initial \"ch\" is assigned to the key `i', the final
\"iu\" is assigned to the key `q', and tones 1, 2, 3, 4, and \e$AGaIy\e(B are
assigned to the keys `q', `w', `e', `r', `t' respectively.

\\<quail-translation-docstring>

To input one-letter words, you type 4 keys, the first two for the
Pinyin of the letter, next one for tone, and the last one is always a
quote (').  For instance, \"vsq'\" input \e$AVP\e(B.  Exceptions are these
letters.  You can input them just by typing a single key.

        Character: \e$A04\e(B \e$A2;\e(B \e$A4N\e(B \e$A5D\e(B \e$A6~\e(B \e$A7"\e(B \e$A8v\e(B \e$A:M\e(B \e$A3v\e(B \e$A<0\e(B \e$A?I\e(B \e$AAK\e(B \e$AC;\e(B
        Key:       a  b  c  d  e  f  g  h  i  j  k  l  m
        Character: \e$ADc\e(B \e$AE7\e(B \e$AF,\e(B \e$AF_\e(B \e$AHK\e(B \e$AH}\e(B \e$AK{\e(B \e$AJG\e(B \e$AWE\e(B \e$ANR\e(B \e$AP!\e(B \e$AR;\e(B \e$ATZ\e(B
        Key:       n  o  p  q  r  s  t  u  v  w  x  y  z

To input two-letter words, you have two ways.  One way is to type 4
keys, two for the first Pinyin, two for the second Pinyin.  For
instance, \"vsgo\" inputs \e$AVP9z\e(B.  Another way is to type 3 keys: 2
initials of two letters, and quote (').  For instance, \"vg'\" also
inputs \e$AVP9z\e(B.

To input three-letter words, you type 4 keys: initials of three
letters, and the last is quote (').  For instance, \"bjy'2\" inputs \e$A11\e(B
\e$A>)Q<\e(B (the last `2' is to select one of the candidates).

To input words of more than three letters, you type 4 keys, initials
of the first three letters and the last letter.  For instance,
\"bjdt\" inputs \e$A11>)5gJSL(\e(B.

To input symbols and punctuation, type `/' followed by one of `a' to
`z', then select one of the candidates."))
