Efficient Deletion and Insertion

As my emacs keybindings journey continues to evolve and to delete more efficiently with delete word it has lead to an interesting issue for me.

Typically, especially in my coding life I will typically copy a string to the clipboard, then go in and delete the target area and insert from the clipboard/kill-ring. Now I have moved from deleting with the delete key to the the M-delete-word concept it seems that deleting words automatically puts this to the clipboard/kill-ring, so when I paste in my original copy it pastes back in the last killed words.

Generally I only ever use kill-line when I want a kill to be copied to the kill-ring and I only ever use the word deletion to just delete in preparation for a yank.

A bit of hunting around on the Interwebs lead to the definition of two new functions to be remapped to avoid the kill-ring.

(defun delete-word-back (arg)
 "Delete characters backward until encountering the beginning of a word.
 With argument ARG, do this that many times."
 (interactive "p")
 (delete-region (point) (progn (backward-word arg) (point))))

(defun delete-word-forward (arg)
 "Delete characters forward until encountering the end of a word.
 With argument ARG, do this that many times."
 (interactive "p")
 (delete-region (point) (progn (forward-word arg) (point))))
