Rack::Stripper: not as sexy as it sounds

Rack::Stripper merely performs String#strip on the body of the response. I wrote this out of a need for this when Rails sends out RSS feeds (for some reason, the XML instruction is replaced with a blank line on outgoing RSS responses).

Add this line to your application's Gemfile and bundle install it:

gem 'rack-stripper'

Rack::Stripper is Rack middleware and can be used with any Rack-based application. In config/application.rb, place the following code.

config.middleware.use Rack::Stripper

Then you'll see Rack::Stripper when you run rake middleware. Simple as that. More info about using Rack middleware with Rails can be found here. If you'd like the middleware to ensure an XML instruction is added to the bodies to XML-based responses, make that line look like this.

config.middleware.use Rack::Stripper, add_xml_instruction: true

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Added some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

I made this. I released it under the WTFPL. See LICENSE for details, if you're into that sort of thing.
