;;; yatexmth.el --- YaTeX math-mode-specific functions
;;;
;;; (c)1993-2013 by HIROSE Yuuji [[email protected]]
;;; Last modified Mon Apr 1 22:44:22 2013 on firestorm
;;; $Id$
;;; Commentary:
;;; [Customization guide]
;;;
;;; By default, you can use two completion groups in YaTeX math
;;; mode, `;' for mathematical signs and `:' for greek letters. But
;;; you can add other completion groups by defining the alist of
;;; `prefix key' vs `completion list' into the variable
;;; YaTeX-math-key-list-private. If you wish to accomplish the
;;; completion as follows(prefix key is `,'):
;;;
;;; KEY COMPLETION
;;; s \sin
;;; S \arcsin
;;; c \cos
;;; C \arccos
;;; :
;;; T \arctan
;;; l \log
;;; hs \sinh
;;;
;;; Typing `s' after `,' makes `\sin', `hs' after `,' makes `\sinh'
;;; and so on. First, you have to define list of key-completion
;;; pairs. Variable name(YaTeX-math-funcs-list) is arbitrary.
;;;
;;; (setq YaTeX-math-funcs-list
;;; '(("s" "sin")
;;; ("S" "arcsin")
;;; :
;;; ("hs" "sinh")))
;;;
;;; Next, define the list of prefix-key vs completion list(defined
;;; above) into the variable YaTeX-math-key-list-private.
;;;
;;; (setq YaTeX-math-key-list-private
;;; '(("," . YaTeX-math-funcs-list)
;;; ("'" . Other-List-if-any)))
;;;
;;; Put these expressions into your ~/.emacs, and you can use this
;;; completion in the math-mode.
;;;
;;; And you can add your favorite completion sequences to the
;;; default completion list invoked with `;', by defining those lists
;;; into variable YaTeX-math-sign-alist-private.
;;; 【イメージ補完の追加方法】
;;;
;;; 標準のイメージ補完では、「;」で始まる数式記号補完と、「:」で始
;;; 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
;;; 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
;;; な補完シリーズを定義する場合を考えてみます。
;;;
;;; 補完キー 補完結果
;;; s \sin
;;; S \arcsin
;;; c \cos
;;; C \arccos
;;; :
;;; T \arctan
;;; l \log
;;; hs \sinh
;;;
;;; 「,」のあとに s を押すと \sin が、hs を押すと \sinh が入力されま
;;; 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)。
;;;
;;; (setq YaTeX-math-funcs-list
;;; '(("s" "sin")
;;; ("S" "arcsin")
;;; :
;;; ("hs" "sinh")))
;;;
;;; 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
;;; と上で定義した補完用変数の登録を行ないます。
;;;
;;; (setq YaTeX-math-key-list-private
;;; '(("," . YaTeX-math-funcs-list)
;;; ("'" . ほかに定義したいシリーズがあれば…)))
;;;
;;; これらを ~/.emacs に書いておけば、math-mode で自分専用のイメージ
;;; 補完が利用できます。
;;; Code:
