;; Features that might be required by this library:
;;
;; `term' `cl' `advice'
;;
;;; Commentary:
;;
;; This package is for creating and managing multiple terminal buffers in Emacs.
;;
;; By default, term.el provides a great terminal emulator in Emacs.
;; But I have some troubles with term-mode:
;;
;; 1. term.el just provides commands `term' or `ansi-term'
;; for creating a terminal buffer.
;; And there is no special command to create or switch
;; between multiple terminal buffers quickly.
;;
;; 2. By default, the keystrokes of term.el conflict with global-mode keystrokes,
;; which makes it difficult for the user to integrate term.el with Emacs.
;;
;; 3. By default, executing *NIX command “exit” from term-mode,
;; it will leave an unused buffer.
;;
;; 4. term.el won’t quit running sub-process when you kill terminal buffer forcibly.
;;
;; 5. Haven’t a dedicated window for debug program.
;;
;; And multi-term.el is enhanced with those features.
;;
;;; Installation:
;;
;; Copy multi-term.el to your load-path and add to your ~/.emacs
;;
;; (require 'multi-term)
;;
;; And setup program that `multi-term' will need:
;;
;; (setq multi-term-program "/bin/bash")
;;
;; or setup like me "/bin/zsh" ;)
;;
;; Below are the commands you can use:
;;
;; `multi-term' Create a new term buffer.
;; `multi-term-next' Switch to next term buffer.
;; `multi-term-prev' Switch to previous term buffer.
;; `multi-term-dedicated-open' Open dedicated term window.
;; `multi-term-dedicated-close' Close dedicated term window.
;; `multi-term-dedicated-toggle' Toggle dedicated term window.
;; `multi-term-dedicated-select' Select dedicated term window.
;;
;; Tips:
;;
;; You can type `C-u' before command `multi-term' or `multi-term-dedicated-open'
;; then will prompt you shell name for creating terminal buffer.
;;
;;; Customize:
;;
;; `multi-term-program' default is nil, so when creating new term buffer,
;; send environment variable of `SHELL' (`ESHELL', `/bin/sh') to `make-term'.
;;
;; And you can set it to your liking, like me: ;-)
;;
;; (setq multi-term-program "/bin/zsh")
;;
;; `multi-term-default-dir' default is `~/', only use when current buffer
;; is not in a real directory.
;;
;; `multi-term-buffer-name' is the name of term buffer.
;;
;; `multi-term-scroll-show-maximum-output' controls how interpreter
;; output causes window to scroll.
;;
;; `multi-term-scroll-to-bottom-on-output' controls whether interpreter
;; output causes window to scroll.
;;
;; `multi-term-switch-after-close' try to switch other `multi-term' buffer
;; after close current one.
;; If you don't like this feature just set it with nil.
;;
;; `term-unbind-key-list' is a key list to unbind some keystroke.
;;
;; `term-bind-key-alist' is a key alist that binds some keystroke.
;; If you don't like default, modify it.
;;
;; `multi-term-dedicated-window-height' the height of a dedicated term window.
;;
;; `multi-term-dedicated-max-window-height' the max height limit that dedicated
;; window is allowed.
;;
;; `multi-term-dedicated-skip-other-window-p' whether skip dedicated term
;; window when use command `other-window' to cycle windows order.
;;
;; All of the above can be customize by:
;; M-x customize-group RET multi-term RET
;;
;;; Change log:
;;
;; 2009/07/04
;; * Add new option `multi-term-dedicated-select-after-open-p'.
;;
;; 2009/06/29
;; * Fix regexp bug.
;;
;; 2009/04/21
;; * Fix a bug that bring at `2009/03/28':
;; It will kill sub-process in other multi-term buffer
;; when we kill current multi-term buffer.
;;
;; 2009/03/29
;; * Add new command `term-send-reverse-search-history'.
;;
;; 2009/03/28
;; * Add new option `multi-term-switch-after-close'.
;;
;; 2009/02/18
;; * Fix bug between ECB and `multi-term-dedicated-close'.
;;
;; 2009/02/05
;; * Prompt user shell name when type `C-u' before command
;; `multi-term' or `multi-term-dedicated-open'.
;; * Fix doc.
;;
;; 2009/01/29
;; * Use `term-quit-subjob' instead `term-interrupt-subjob'.
;; * Fix doc.
;;
;; 2009/01/13
;; * Rewrite advice for `pop-to-buffer' to avoid `pop-to-buffer' not effect
;; when have many dedicated window in current frame.
;; * Rewrite advice for `delete-other-windows' to avoid use common variable
;; `delete-protected-window-list' and use `window-dedicated-p' instead.
;; Remove variable `delete-protected-window-list' and function
;; `multi-term-dedicated-match-protected-window-p'.
;;
;; 2009/01/06
;; * Improve document.
;;
;; 2008/12/29
;; * Remove option `multi-term-current-window-height' and
;; function `multi-term-current-directory'.
;; * Add some functions to make get dedicated term buffer,
;; those functions is beginning with `multi-term-dedicated-'.
;; * Modified advice `delete-window', make command `delete-window'
;; and delete dedicated window, but will remember window height
;; before deleted.
;; * Don't remember dedicated window height if larger than max value.
;; * Fix some bug with `delete-other-windows' and window configuration.
;; And this bug exists with another extension `sr-speedbar'.
;; * Add new variable `delete-protected-window-list' for protected
;; special window that won't be deleted.
;; This variable is common for any extension that use dedicated
;; window.
;; * Fix doc.
;;
;; 2008/12/21
;; * Default bind `C-m' with `term-send-input'.
;;
;; 2008/12/10
;; * Improve customize interface.
;; * Setup customize automatically, don't need to user setup it up.
;; * Add option `multi-term-try-create'.
;; * Make function `multi-term-switch' accept offset argument.
;; * Fix doc.
;;
;; 2008/10/22
;; * Add variable `multi-term-current-window-height'.
;; * Add variable `multi-term-buffer-name'.
;; * Add variable `term-unbind-key-list'.
;; * Add variable `term-rebind-key-alist'.
;; * Move key setup and some extension from `term-extension.el'.
;; * Create new function `multi-term-keystroke-setup'.
;; * Fix doc.
;;
;; 2008/09/19
;; * First released.

By default, function `display-buffer' can't display buffer in selected window
if current window is `dedicated'.
So function `display-buffer' conflicts with `sr-speedbar' window, because
`sr-speedbar' window is a `dedicated' window.
That is to say, when current frame just have one `non-dedicated' window,
any functions that uses `display-buffer' can't split windows
to display buffer, even when the option `pop-up-windows' is enabled.
And the example function that can induce the problem is `pop-to-buffer'.
This advice will fix this problem when current frame just have one `non-dedicated' window."
