This package is designed to 30;; facilitate transitioning from Brief to (XE|E)macs with a minimum 31;; amount of hassles. 32 33;; Enable this package by putting (require 'crisp) in your .emacs and 34;; use M-x crisp-mode to toggle it on or off. 35 36;; This package will automatically load the scroll-all.el package if 37;; you put (setq crisp-load-scroll-all t) in your .emacs before 38;; loading this package. If this feature is enabled, it will bind 39;; meta-f1 to the scroll-all mode toggle. The scroll-all package 40;; duplicates the scroll-alling feature in CRiSP. 41 42;; Also, the default keybindings for brief/CRiSP override the M-x 43;; key to exit the editor. If you don't like this functionality, you 44;; can prevent this behavior (or redefine it dynamically) by setting 45;; the value of `crisp-override-meta-x' either in your .emacs or 46;; interactively. The default setting is t, which means that M-x will 47;; by default run `save-buffers-kill-emacs' instead of the command 48;; `execute-extended-command'. 49 50;; Finally, if you want to change the string displayed in the modeline 51;; when this mode is in effect, override the definition of 52;; `crisp-mode-modeline-string' in your .emacs. The default value is 53;; " *Crisp*" which may be a bit lengthy if you have a lot of things 54;; being displayed there. 55 56;; All these overrides should go *before* the (require 'crisp) statement. 57 58;;; Code: 59 60;; local variables 61 62(defgroup crisp nil 63 "Emulator for CRiSP and Brief key bindings." 64 :prefix "crisp-" 65 :group 'emulations) 66 67(defvar crisp-mode-map (let ((map (make-sparse-keymap))) 68 map) 69 "Local keymap for CRiSP emulation mode. 70All the bindings are done here instead of globally to try and be 71nice to the world.") 72 73(defcustom crisp-mode-modeline-string " *CRiSP*" 74 "*String to display in the modeline when CRiSP emulation mode is enabled." 75 :type 'string 76 :group 'crisp) 77 78;;;###autoload 79(defcustom crisp-mode nil 80 "Track status of CRiSP emulation mode. 81A value of nil means CRiSP mode is not enabled.
