;;; Window manager for GNU Emacs
;;;[What is Windows?]
;;; You can divide the screen of GNU Emacs as many as you like.
;;; Since efficiency of implementation or so depends much on the
;;; style of window division, you may have your own style of
;;; partitioning. But if you switch the mode to e-mail mode or
;;; NetNews mode, they break your favorite style.
;;; Windows.el enables you to have multiple favorite window
;;; configurations at the same time, and switch them. Furthermore,
;;; it can save all window configurations and some global or
;;; buffer-local variables into a file and restore them correctly.
;;; **For Emacs 19 or later**
;;; This package provides the `named(numbered) frame' that can be
;;; selected directly with their name. With revive.el, all frames'
;;; displaying buffers, window configurations and size can be saved
;;; and restored.
;;; Put windows.el into the directory load-path indicates, and put
;;; the following expressions into your ~/.emacs.
;;; (require 'windows)
;;; (win:startup-with-window)
;;; (define-key ctl-x-map "C" 'see-you-again)
;;; If your are thinking of creating patch for windows.el, please
;;; don't forget to consider about compatibility of various emacsen.
;;; * Do not rely on other package. e.g., 'when relies on
;;; 'cl package.
;;; * Test your patch on as old/new emacs as you can have.
;;; Anyway, feel free to hack. I'll make a glue for various emacsen
;;; upon your patches if you can't test.
;;;[Key Bindings]
;;; The default prefix key stroke for Windows is `C-c C-w'. If it
;;; causes you some troubles, see the section `Customizations'.
;;; Here are the default key bindings.
;;; C-c C-w 1 Switch to window 1 (Q)
;;; C-c C-w 2 Switch to window 2 (Q)
;;; :
;;; C-c C-w 9 Switch to window 9 (Q)
;;; C-c C-w 0 Swap windows with the buffer 0 (Q)
;;; (Select unallocated frame(Emacs 19))
;;; C-c C-w SPC Switch to window previously shown (Q)
;;; C-c C-w C-n Switch to next window
;;; C-c C-w C-p Switch to previous window
;;; C-c C-w ! Delete current window (Q)
;;; C-c C-w C-w Window operation menu
;;; C-c C-w C-r Resume menu
;;; C-c C-w C-l Local resume menu
;;; C-c C-w C-s Switch task
;;; C-c C-w = Show window list (Q)
;;; The key strokes to select windows from 1 to 9 must be
;;; frequently used, so the alternative key strokes `C-c [Num.]' are
;;; available by default (And any function with (Q)mark can be
;;; invoked without C-w). To disable these quick key strokes, set
;;; the variable win:quick-selection to `nil' in your ~/.emacs.
;;;(for Emacs19 or later)
;;; Windows.el manages maximum 10 (or more if you configure)
;;; frames. The first frame is `window#1'. If you want to create a
;;; new frame as `window#2', type `C-c C-w 2'. You can create or
;;; switch numbered frames as many as you want. Unlike standard
;;; Emacs's frame selection (`C-x 5 o'), windows.el enables you to
;;; go to the desired frame directly.
;;; For detailed frame management, read the section `Other
;;; functions'. In that section, the term `window' is used to refer
;;; the frame.
;;;(for Emacs18 or emacs -nw)
;;; Windows.el has 10 window buffers, from 0 to 9. But you can
;;; use the buffer from 1 to 9, the buffer 0 is reserved for the
;;; most recently used window (This is not true for the frame
;;; environment of Emacs 19).
;;; If you have wrote `win:startup-with-window' in your .emacs,
;;; the initial window configuration is memorized in the buffer 1.
;;; Otherwise you have to memorize it by typing `C-c C-w 1'.
;;; Anyway, say you are editing some program in buffer 1.
;;; After a while, a mail has arrived. You may wish to assign a
;;; mail mode configuration to the buffer 2. Type `C-c C-w 2' to
;;; create the buffer 2, and you will see the `window creation
;;; menu':
;;; C)reate D)uplicate P)reserve F)indfile B)uff X)M-x k)KeyFunc&exit N)o:
;;; in the minibuffer. Since you don't need the current window
;;; configuration (programming configuration) to read mails, type
;;; `c', stands for Create, to create the new window configuration.
;;; Then, after invoke the mail reader, current window configuration
;;; will turn to mail oriented one. (Of course you can directly call
;;; e-mail mode by typing `x' at the window creation menu.) When you
;;; finish to read your mail, you can return to programming
;;; configuration with `C-c C-w 1'.
;;; Let's read the NetNews. M-x gnus... O.K.! You've read. You
;;; may have typed `q' to quit gnus until yesterday. But you don't
;;; have to do it from today. You can go back to programming
;;; immediately by typing `C-c C-w 1'! Oops, you have not created
;;; the new configuration buffer yet. So the window you see is
;;; still the window 1. If you switch the window to another, you'll
;;; lose the configuration in the buffer 1. In this case, type `p'
;;; (stands for Preserve) at the window creation menu after typing
;;; `C-c C-w 3'(%1). Windows.el doesn't update the buffer 1 and
;;; saves the current window configuration of the NetNews into the
;;; buffer 3.
;;; **On Emacs-19, you can't preserve the buffer contents unless you
;;; have saved it into the resume file described below.
;;; Then, type `C-c C-w 2' to read the mail, type `C-c C-w 3' when
;;; you are tired with programming. `C-c C-w SPC' is very
;;; convenient when you want to exchange two configurations.
;;; If you forget what windows are allocated to the buffers, type
;;; `C-c C-w =' to display the configuration buffer names and their
;;; corresponding editing buffer names in the menu buffer. The
;;; entry preceded by `*' is the selected buffer and the entry with
;;; `+' is the buffer previously selected(that is, the buffer `C-c
;;; C-w SPC' will select). In this buffer, you can move cursor with
;;; `n' or `p', and select that window with SPC. Type `?' for more
;;; information.
;;; (%1)
;;; At a point of this time, while window configuration buffer holds
;;; the programming environment, the screen of GNUS is displayed.
;;; And, notice that `p'(Preserve) at the window creation menu
;;; doesn't work when the Windows uses `frame' as window unit on
;;; Emacs 19.
;;;[Other functions]
;;; Typing `C-c C-w C-w' displays the menu as follows.
;;; N)ext P)rev R)ecent D)elete K)ill S)ave2buf L)oad-from-buf A)save-As
;;; In this menu, `n', `p' is for switching window to the next or
;;; previous, `r' is for recovering the window recently seen before
;;; the window switching operation(%2), `d' is for deleting current
;;; window. `k' is same as `d' except closing all visible file(s).
;;; And type `s' to save the current window configuration into the
;;; corresponding buffer, `a' to save the current window
;;; configuration into specified buffer. Note that `s' and `l' is
;;; unavailable on frame environment.
;;; (%2)
;;; When using frame on Emacs 19, it is impossible to store a frame
;;; recently seen, so `r' (win-recent-window) selects a frame that
;;; is not allocated to Windows instead, if any (equivalent to `C-c
;;; C-w 0').
;;; When you create the new window, you see the window creation
;;; menu which ask you how to handle the current configuration
;;; buffer and what configuration the new window must be. The
;;; entries of the prompt stand for the followings.
;;; Create After saving the current window
;;; configuration into the current buffer,
;;; create a newly allocated window.
;;; Duplicate After saving the current window
;;; configuration into the current buffer,
;;; create the new window with the same
;;; configuration as the current one.
;;; Preserve Without updating the current buffer,
;;; use the current window configuration
;;; as the new window. This function is not
;;; available on Emacs 19 with frame.
;;; Findfile Find-file on new window.
;;; Buff Switch to buffer on new window.
;;; M-x Call a command on new window.
;;; No Cease window creation.
;;; Windows.el can resume your environment with a help of
;;; `revive.el'. You can see the menu by typing `C-c C-w C-r'.
;;; A)save-all R)estore-all S)ave-this L)oad-this N)Load# ~)read-~
;;; Type `a' to save all window configurations into a file, and type
;;; `r' to restore configurations saved in that file. `s' to save
;;; the current window configuration, `l' to load current window
;;; from file, `n' to load a window specified by a number. And use
;;; `~' when you type `a' instead of `r' by mistake. And it is much
;;; more convenient to kill emacs with `C-x C'. If you want to
;;; resume that context, call `resume-windows' (or C-c C-w C-r r)
;;; just after starting Emacs.
;;;[Local resume]
;;; If you want to have many sets of window configurations, type
;;; `C-c C-w C-l' to specify the directory where another
;;; configuration file is to resid, and operate in the same way as
;;; you do in resume menu described above. You can change sets of
;;; configurations directory by directory.
;;; By the way, most of tasks are being done in a certain
;;; directory. If you have a couple of or more jobs to do at once,
;;; the function `win-switch-task' is very useful to switch your
;;; tasks. It saves the current set of window configurations into
;;; current configuration file, flushes buffers, and reads the next
;;; set of window configurations for the next task from another
;;; configuration file.
;;; To change the prefix key stroke to `C-c w' for example,
;;; put the following expressions into your ~/.emacs.
;;; (setq win:switch-prefix "\C-cw")
;;; (define-key global-map win:switch-prefix nil)
;;; (define-key global-map "\C-cw1" 'win-switch-to-window)
;;; And you can also change the key stroke of window selection to
;;; `a' to `z' other than `1' to `9'.
;;; (setq win:switch-prefix "\C-cw")
;;; (define-key global-map win:switch-prefix nil)
;;; (define-key global-map "\C-cwb" 'win-switch-to-window)
;;; (setq win:base-key ?`) ;; '`' is before 'a'
;;; (setq win:max-configs 27) ;; '`' to 'z' are 27 chars.
;;; (setq win:quick-selection nil) ;; Not assign `C-c LETTER'
;;; Notice that '`' is the previous character of 'a' in ASCII code,
;;; and that C-c w ` is bound to swap the configuration in the
;;; buffer '`' and the current buffer.
;;; If you don't use `frame' even on Emacs 19 with X Window. Set
;;; win:use-frame to nil in ~/.emacs.
;;; If you hate raising of frames at win-save-all-configurations,
;;; set win:no-raise-at-save to t.
;;;[For frame users]
;;; When you start to use windows.el, you may create a new frame
;;; with old operation `C-x 5 f' or so. Frames created with
;;; standard frame operation are not marked in the windows ring. To
;;; incorporate sucn an orphan frame into windows ring, type `C-c
;;; C-w C-w' and select `A)save-as' from the menu. And if you want
;;; to switch to orphan frames, type `C-c C-w 0', which switches
;;; frame to isolated frames and rotate them.
;;; By default, windows.el name a frame title (bar) as follows.
;;; Emacs[1]:*scartch*
;;; This causes frame title always representing the frame number.
;;; So you can switch to any of them with key operation of your
;;; window manager, `fvwm' for example:
;;; --- .fvwmrc ---
;;; key 1 A C Warp "" Emacs[1]
;;; key 2 A C Warp "" Emacs[2]
;;; :
;;; key 9 A C Warp "" Emacs[9]
;;; If you use fvwm2
;;; AddToFunc DeiconifyFocusAndWarp "I" Iconify -1
;;; + "I" FocusAndWarp $0 $1
;;; Key 1 A C Next [Emacs?1?:*] DeiconifyFocusAndWarp
;;; :
;;; Key 9 A C Next [Emacs?9?:*] DeiconifyFocusAndWarp
;;; #(fvwm2 can't escape [ and ], so cause matches with them by ?s.)
;;; Thus C-1, C-2, ..., C-9 directly select window frame `Emacs[1]'
;;; through `Emacs[9]'.
;;; In this hook, two variables `frame' and `index', which have
;;; frame object, frame number respectively, are available.
;;; This program was inspired from `screen', the window manager
;;; for VT100 emulation terminal, and operations are fundamentally
;;; based on it. But there is no compatibility.
;;; When restoring frames of Emacs 19, the order of frame
;;; allocation is not restored, that is, its order depends on the
;;; frame where win-load-all-configurations is called. No frame
;;; positions are not recovered neither.
