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))))
