;;; Commentary:

;; A sensible fuzzy file chooser with a beautiful Mac OS X GUI.
;;
;; This minimal enhancement to textmate-mode calls the external
;; PeepOpen.app when you hit Command-T (or equivalent).

;;    ⌘T - Go to File

;;; Installation:

;; This plugin assumes that you've already loaded Chris Wanstrath's
;; textmate.el in your emacs configuration. Load this file afterward.
;;
;; Copy this file to ~/.emacs.d/vendor/peepopen.el (or use the menu
;; item in the PeepOpen application).
;;

;; You'll also need textmate.el:
;;
;;   $ cd ~/.emacs.d/vendor
;;   $ git clone git://github.com/defunkt/textmate.el.git

;; Finally, require both libraries and activate textmate-mode.
;; In most Emacs distributions, you'll do this in ~/.emacs.d/init.el
;; or your personal configuration file.
;;
;; In Aquamacs, this goes in ~/Library/Preferences/Aquamacs Emacs/Preferences.el.

;;   (add-to-list 'load-path "~/.emacs.d/vendor/textmate.el")
;;   (require 'textmate)
;;   (add-to-list 'load-path "~/.emacs.d/vendor/")
;;   (require 'peepopen)
;;   (textmate-mode)

;; For Emacs 23 or Aquamacs, use this to open files in the existing frame:
;;
;;   (setq ns-pop-up-frames nil)
