+
+;;; Commentary:
+
+;; This library offers a single mode that will delete all trailing
+;; whitespace before saving any file. It tries to be intelligent
+;; enough to only do this for modes where trailing whitespace is not
+;; meaningful. Currently it only keeps whitespace around in
+;; `markdown-mode' since it uses two spaces at the end of a line to
+;; signify a line break.
+;;
+;; To use this mode in all buffers, add the following to your init
+;; file:
+;;
+;;    (require 'destroy-trailing-whitespace)
+;;    (global-destroy-trailing-whitespace-mode)
+;;
+;; To use this mode in just some buffers add it to your preferred
+;; hook. For example, to use it only in `prog-mode' buffers:
+;;
+;;    (require 'destroy-trailing-whitespace)
+;;    (add-hook 'prog-mode-hook 'destroy-trailing-whitespace-mode)
+
+;;; Code:
+
+(defun destroy-trailing-whitespace ()
+  "Delete trailing whitespace everywhere, except in Markdown buffers."
+  (if (not (eq major-mode 'markdown-mode))
+      (delete-trailing-whitespace)))
+
+;;;###autoload
+(define-minor-mode destroy-trailing-whitespace-mode
+  "Destroy all trailing whitespace before saving the buffer."
+  :lighter ""
+  (if destroy-trailing-whitespace-mode
+      (add-hook 'before-save-hook 'delete-trailing-whitespace nil :local)
+    (remove-hook 'before-save-hook 'delete-trailing-whitespace :local)))
+
+;;;###autoload
+(define-minor-mode global-destroy-trailing-whitespace-mode
+  "Destroy all trailing whitespace before saving any open buffer."
+  :lighter "" :global t
+  (if global-destroy-trailing-whitespace-mode
+      (add-hook 'before-save-hook 'destroy-trailing-whitespace)
+    (remove-hook 'before-save-hook 'destroy-trailing-whitespace)))
+
