Scrubba: Clean your strings!

Scrubba is a tiny gem to strip and normalize whitespace. It provides a few convenient methods for working with ActiveRecord/ActiveModel/ActiveAttr/ActiveNode attributes too.

Add this line to your application's Gemfile:

gem 'scrubba'

And then execute:

$ bundle

Or install it yourself as:

$ gem install scrubba

Standalone:

require "scrubba"

some_str = " foo \t bar "
Scrubba.strip(some_str) #=> "foo \t bar"
Scrubba.collapse(some_str) #=> " foo bar "

In an ActiveRecord model:

require "scrubba"

class Post < ActiveRecord::Base
  include Scrubba::ActiveMethods

  scrub :title, :slug, strip: true
  scrub :body, collapse: true
end

Protip: If you use Emacs, insert a Unicode space in your test data with M-x insert-char and verify it with M-x describe-char.
