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:
And then execute:
Or install it yourself as:
$ gem install scrubba
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.
