Page on trailing whitespace handling

New page

There are different ways to handle trailing whitespace in Emacs

== Visualize trailing whitespace ==

Just set the {{Variable|show-trailing-whitespace}} variable:
{{Snippet|(setq show-trailing-whitespace t)}}

== Delete trailing whitespace ==

You can delete trailing whitespace in the entire buffer using {{Command|delete-trailing-whitespace}}.

To automate trailing whitespace deletion before saving the buffer in certain modes, you can add local hooks, e.g:
{{Snippet|(add-hook 'c-mode-hook (lambda () (add-to-list 'write-file-functions 'delete-trailing-whitespace)))}}
