Whiteout

Remove annoying trailing whitespace from files.

Warning: this is alpha-quality code written with the assistance of several glasses of gin. It's entirely possibly that it may eat your files, your children, or your future, and I disclaim responsibility for any of that.

RubyGems:

$ gem install whiteout
$ whiteout -h

$ echo -e "foo  \nbar" | whiteout
foo
bar
$ whiteout file1.rb file2.rb # modified in place
