Removing whitespace

Why?

"Trailing whitespace is indeed commit noise."

Sublime Text

Just drop this in one of your settings files:

"trim_trailing_white_space_on_save": true

Textmate

Open the bundle editor (⌃⌥⌘B) and open “Text” → “Menu Actions” → “Converting / Stripping” → “Remove Trailing Spaces in Document / Selection”.

Then in the drawer put callback.document.export in Semantic Class and Document / Replace Document as Input / Output.

• Another way to make sure to remove all trailing whitespace in a file is to set an autocmd in your .vimrc file. Every time the user issues a :w command, Vim will automatically remove all trailing whitespace before saving.

autocmd BufWritePre * :%s/\s\+$//e
