Remove Trailing Whitespace With Vim

Posted By Weston Ganger

Vim is awesome and it can remove all trailing whitespace automatically.

For the Current File:

# on every file save
autocmd BufWritePre * :%s/\s\+$//e

# on certain file extension
autocmd BufWritePre *.rb :%s/\s\+$//e

# on certain file types
autocmd FileType ruby,php,java autocmd BufWritePre <buffer> :%s/\s\+$//e
