Module: Rack::Tidy

Defined in:

lib/rack/tidy.rb,
lib/rack/tidy/cleaner.rb

Overview

Tidy Markup Cleaner for Rack

Rack::Tidy cleans text/html markup by automatically indenting and reformatting content. Best results are achieved with valid markup, when you simply want to use this component to produce clean (X)HTML rendered by templating systems such as ERb.

Rack::Tidy relies on the power of the Tidy gem and defaults to settings based on convention. However, you can override these through configuration.

Usage

Within a rackup file (or with Rack::Builder):

require 'rack/tidy'
use Rack::Tidy,
  :ignore_paths => ['/admin', '/cms'],
  'indent-spaces' => 4
run app

Rails example:

# above Rails::Initializer block
require 'rack/tidy'

# inside Rails::Initializer block 
config.middleware.use Rack::Tidy,
  :ignore_paths => ['/admin', '/cms'],
  'indent-spaces' => 4
