白井です。
# 思ったより早く仕事が片付いたので、家に帰ろうかとも思ったのですが、
# 気を取り直して、新しいmew-caesar.elをお届けします。
変更点はというと、
1. tmやSEMIを持っていない人のために、nkf等の外部プログラムでも
caesar暗号化/復号化が出来るようにした。
以下の様な、余り素敵でない選択方法です。
(setq mew-caesar-use-tm t|nil|"ext")
;; caesar package select t => tm:caesar-region
;; nil => mule-caesar-region
;; "ext" => mew-caesar-ext-prog
# こういうの、っていいんだろうか？
# やっぱ、それぞれを別の関数にわけて、defvarした方がいいのかな？
また、外部プログラム関連の設定は以下の通りです。
(defvar mew-caesar-ext-prog "nkf")
(defvar mew-caesar-ext-prog-arg "-rj")
ちなみに、私の環境ではMule for Win32だけ
(setq mew-caesar-ext-prog-arg "-rs")
にしないと文字化けしましたが、後はデフォルト値でOKでした。
うわさでは、xemacsでも文字化けするそうですが、環境を持っていない
ので確認していません。
## 私のMedowは"-rj"で化けないかわりに、普通のsjisをはくプログラムの
## 出力が化けます。^^;;;
2. nkfを使うと、regionだけ暗号化したい復号化したいというのがめん
どくさいので、
(defun mew-caesar-region (min max)
という関数を新設しました。
ちなみに、mew-distに投げるのは、まだまだ、maltipart editorが変わ
りそうなのでその辺を見計らってからにしようかなぁと思っています。
## nkfを使うというアイデアとパッチを下さいました、やまの@五反田
## さん、ありがとうございました。やっと作りました。m(__)m
