;;;
;;; Commentary:
;;;
;;; Resume Emacs: revive.el
;;;
;;;[What is `revive'?]
;;;
;;; Revive.el saves current editing status including the window
;;; splitting configuration, which can't be recovered by
;;; `desktop.el' nor by `saveconf.el', into a file and reconstructs
;;; that status correctly.
;;;
;;;[Installation]
;;;
;;; Put revive.el into your elisp directory included in load-path
;;; and write the next expressions.
;;;
;;; (autoload 'save-current-configuration "revive" "Save status" t)
;;; (autoload 'resume "revive" "Resume Emacs" t)
;;; (autoload 'wipe "revive" "Wipe Emacs" t)
;;;
;;; And define favorite keys to those functions. Here is a sample.
;;;
;;; (define-key ctl-x-map "S" 'save-current-configuration)
;;; (define-key ctl-x-map "F" 'resume)
;;; (define-key ctl-x-map "K" 'wipe)
;;;
;;;[How to use]
;;;
;;; Call `save-current-configuration' (`C-x S' if you define key as
;;; above) when you want to save current editing status and call
;;; `resume' to restore it. Numerical prefix arg to them specifies
;;; the buffer number in which the editing status will be saved.
;;;
;;; [Sample Operations]
;;; C-u 2 C-x S ;save status into the buffer #2
;;; C-u 3 C-x F ;load status from the buffer #3
;;;
;;;[Save Variables]
;;;
;;; Revive.el can save global or local variables. The default
;;; variables to be saved are in revive:save-variables-global-default
;;; and revive:save-variables-local-default. If you want to save other
;;; global/local variables, define them in
;;; revive:save-variables-global-private or
;;; revive:save-variables-local-private in a form of a list. If you
;;; are using `gmhist', the next expression in ~/.emacs is useful.
;;;
;;; (setq revive:save-variables-global-private
;;; '(file-history buffer-history minibuffer-history))
;;;
;;;[Restoring abnormal buffers]
;;;
;;; The variable revive:major-mode-command-alist-default holds the
;;; list of major-mode name vs. command name. For example,
;;; mh-rmail command sees the directory ~/Mail/inbox/ and sets the
;;; major-mode to 'mh-folder-mode. And gnus command sets the
;;; major-mode to 'gnus-Group-mode. If you want to define other
;;; relations between major-mode and command, set the user variable
;;; revive:major-mode-command-alist-private as follows:
;;;
;;; (setq revive:major-mode-command-alist-private
;;; '((your-own-mode . your-own)
;;; (foo-mode . foo)
;;; ("*Hanoi*" . hanoi)
;;;
;;; it tells revive.el to execute the corresponding command when the
;;; saved configuration has the buffer with that major-mode. To know
;;; the major-mode of a certain buffer, type `M-ESC' and `major-mode
;;; CR'. And as you see above, buffer-name string can be used
;;; instead of major-mode symbol.
;;;
;;; For other special modes that cannot be resumed by executing
;;; certain function, define a function to resume and declare it in
;;; the variable revive:major-mode-command-alist-private. In that
;;; function, the following values are available.
;;;
;;; (revive:prop-file-name x) ;file name
;;; (revive:prop-buffer-name x) ;buffer name
;;; (revive:prop-major-mode x) ;major-mode
;;; (revive:prop-point x) ;(point)
;;; (revive:prop-mark x) ;(mark)
;;; (revive:prop-varlist x) ;alist of pairs of (var . val)
;;;
;;;[For programmers]
;;;
;;; This program provides two powerful functions:
;;;
;;; * current-window-configuration-printable
;;; * restore-window-configuration
;;;
;;; When you want to save a screen your program manages into a file,
;;; and restore it, save the return value of current-window-
;;; configuration-printable, and read and give it to restore-window-
;;; configuration.
;;;
;;; *Sample*
;;; ;;To save
;;; (insert (prin1-to-string (current-window-configuration-printable)))
;;; ;;To restore
;;; (restore-window-configuration (read (current-buffer)))
;;;
;;; Since set-window-configuration cannot set the configuration of
;;; other frame, the program as below should be useful.
;;;
;;; *Sample*
;;; (defun frame-copy-configuration (nth)
;;; "Copy confinguration of current frame to NTH next frame."
;;; (let ((config (current-window-configuration-printable)))
;;; (other-frame nth)
;;; (restore-window-configuration config)))

;;;
;;;【reviveとは】
;;;
;;; revive.el を使うと、Emacs 使用時の状態をファイルにセーブして、
;;; 次回 Emacs を起動する時にその状態に復帰することができます。もち
;;; ろんウィンドウの分割状態も復元されるので saveconf や desktop で
;;; いらいらしていた人にもお勧めです。
;;;
;;;【組み込み方】
;;;
;;; revive.el を load-path の通ったディレクトリに入れ、~/.emacs に
;;; 以下の記述を入れてください。
;;;
;;; (autoload 'save-current-configuration "revive" "Save status" t)
;;; (autoload 'resume "revive" "Resume Emacs" t)
;;; (autoload 'wipe "revive" "Wipe emacs" t)
;;;
;;; そして上の関数を好きなキーに割り当ててください。以下は例です。
;;;
;;; (define-key ctl-x-map "S" 'save-current-configuration)
;;; (define-key ctl-x-map "F" 'resume)
;;; (define-key ctl-x-map "K" 'wipe)
;;;
;;;【使い方】
;;;
;;; 上の define-key をした場合には、C-x S で現在の編集状態をセーブ
;;; することができます。save-current-configuration 関数に数引数をつ
;;; けると複数の状態を別々にセーブできます。「C-u 2 C-x S」とすると2
;;; 番のバッファに現状をセーブできます。これをロードする時も同様に
;;; 「C-u 2 C-x F」とタイプすると2番のバッファから状態をロードします。
;;;
;;;【変数のセーブ】
;;;
;;; 変数の値もセーブしておくことができます。デフォルトでセーブする
;;; global 変数は revive:save-variables-global-default に、local 変
;;; 数は revive:save-variables-local-default に定義されています。ほ
;;; かの変数も保存したい場合は、revive:save-variables-global-private
;;; に global 変数名を、revive:save-variables-local-private に local
;;; 変数名をそれぞれリストの形で定義しておきます。例えば gmhist を使っ
;;; ている場合には、
;;;
;;; (setq revive:save-variables-global-private
;;; '(file-history buffer-history minibuffer-history))
;;;
;;; などと ~/.emacs に書いておくと快適でしょう。
;;;
;;;【普通でないバッファの扱い】
;;;
;;; mh-rmail ではカレントバッファが mh-folder-mode, gnus ではカレ
;;; ントバッファが gnus-Group-mode になります。この対応関係は、変数
;;; revive:major-mode-command-alist-default に書かれています。この変
;;; 数に登録されている以外のものを定義したい場合は、
;;;
;;; (setq revive:major-mode-command-alist-private
;;; '((hogehoge-mode . hoge)
;;; (herohero-mode . herohero)
;;; ("タイプ＆メニュー" . trr)))
;;;
;;; のように revive:major-mode-command-alist-private の値を設定する
;;; と次回 resume した時に自動的に対応するコマンドが起動されます。ま
;;; た上の例にあるように、major-mode(シンボル)の代わりに buffer-name
;;; (文字列)を指定することもできます。
;;;
;;; また、SKKの辞書のようにリジュームするとうまく動かなくなってし
;;; まうバッファがある場合は、変数 revive:ignore-buffer-pattern にそ
;;; のバッファ名がマッチするような正規表現を設定してください。
;;;
;;;【プログラムから使う】
;;;
;;; 英語版ドキュメント [For programmers] の項を参照してください。
;;;
;;;【あとがき】
;;;
;;; 最初は resume というファイル名だったのですが、Emacs 19 のディ
;;; レクトリに resume.el というファイルがあってショックを受けました。
;;; こちらはコマンドラインで何回 emacs と打っても、既に起動している
;;; emacs にファイルを渡すというだけの(ピーー)プログラムで「どこが
;;; resume やねん」と言いたくなりましたが我慢して revive.el にリネー
;;; ムしました。ああまったく、saveconf でも desktop でもなし得なかっ
;;; たウィンドウ分割状態の復元をサポートしたと言うのに…、なんてこと
;;; は英語版には書けないな:-)。
;;;
