10 ;;; By default, you can use two completion groups in YaTeX math
11 ;;; mode, `;' for mathematical signs and `:' for greek letters. But
12 ;;; you can add other completion groups by defining the alist of
13 ;;; `prefix key' vs `completion list' into the variable
14 ;;; YaTeX-math-key-list-private. If you wish to accomplish the
15 ;;; completion as follows(prefix key is `,'):
16 ;;;
17 ;;; KEY COMPLETION
18 ;;; s \sin
19 ;;; S \arcsin
20 ;;; c \cos
21 ;;; C \arccos
22 ;;; :
23 ;;; T \arctan
24 ;;; l \log
25 ;;; hs \sinh
26 ;;;
27 ;;; Typing `s' after `,' makes `\sin', `hs' after `,' makes `\sinh'
28 ;;; and so on. First, you have to define list of key-completion
29 ;;; pairs. Variable name(YaTeX-math-funcs-list) is arbitrary.
30 ;;;
31 ;;; (setq YaTeX-math-funcs-list
32 ;;; '(("s" "sin")
33 ;;; ("S" "arcsin")
34 ;;; :
35 ;;; ("hs" "sinh")))
36 ;;;
37 ;;; Next, define the list of prefix-key vs completion list(defined
38 ;;; above) into the variable YaTeX-math-key-list-private.
39 ;;;
40 ;;; (setq YaTeX-math-key-list-private
41 ;;; '(("," . YaTeX-math-funcs-list)
42 ;;; ("'" . Other-List-if-any)))
43 ;;;
44 ;;; Put these expressions into your ~/.emacs, and you can use this
45 ;;; completion in the math-mode.
46 ;;;
47 ;;; And you can add your favorite completion sequences to the
48 ;;; default completion list invoked with `;', by defining those lists
49 ;;; into variable YaTeX-math-sign-alist-private.
51 ;;; 【イメージ補完の追加方法】
52 ;;;
53 ;;; 標準のイメージ補完では、「;」で始まる数式記号補完と、「:」で始
54 ;;; まるギリシャ文字補完が使用可能ですが、これ以外の文字で始まる補完
55 ;;; シリーズも定義することができます。例えば、「,」で始まる次のよう
56 ;;; な補完シリーズを定義する場合を考えてみます。
57 ;;;
58 ;;; 補完キー 補完結果
59 ;;; s \sin
60 ;;; S \arcsin
61 ;;; c \cos
62 ;;; C \arccos
63 ;;; :
64 ;;; T \arctan
65 ;;; l \log
66 ;;; hs \sinh
67 ;;;
68 ;;; 「,」のあとに s を押すと \sin が、hs を押すと \sinh が入力されま
69 ;;; す。このような補完リストの登録は以下のようにします(変数名は任意)。
70 ;;;
71 ;;; (setq YaTeX-math-funcs-list
72 ;;; '(("s" "sin")
73 ;;; ("S" "arcsin")
74 ;;; :
75 ;;; ("hs" "sinh")))
76 ;;;
77 ;;; さらに、「,」を押した時にイメージ補完が始まるよう次の変数に、起動キー
78 ;;; と上で定義した補完用変数の登録を行ないます。
79 ;;;
80 ;;; (setq YaTeX-math-key-list-private
81 ;;; '(("," . YaTeX-math-funcs-list)
82 ;;; ("'" . ほかに定義したいシリーズがあれば…)))
83 ;;;
84 ;;; これらを ~/.emacs に書いておけば、math-mode で自分専用のイメージ
85 ;;; 補完が利用できます。
