elpa-ws-butler

Description

This package provides ws-butler-mode and ws-butler-global-mode. Upon saving a file in Emacs, these modes delete trailing whitespace on lines of the buffer that have been edited.

As compared with simply calling delete-trailing-whitespace in your before-save-hook, ws-butler has the advantage of not cluttering up version control commits with whitespace cleanup outside of the part of the file you have edited.
