# frozen_string_literal: true
# = Radius (<tt>radius</tt>)
#
# {Radius}[http://radius.rubyforge.org] is the template language used by {Radiant CMS}[http://radiantcms.org]. It is
# a tag language designed to be valid XML/HTML.
#
# === Example
#
# <html>
# <body>
# <h1><r:title /></h1>
# <ul class="<r:type />">
# <r:repeat times="3">
# <li><r:hello />!</li>
# </r:repeat>
# </ul>
# <r:yield />
# </body>
# </html>
#
# === Usage
#
# To render a template such as the one above.
#
# scope = OpenStruct.new
# scope.title = "Radius Example"
# scope.hello = "Hello, World!"
#
# require 'radius'
# template = Tilt::RadiusTemplate.new('example.radius', :tag_prefix=>'r')
# template.render(scope, :type=>'hlist'){ "Jackpot!" }
#
# The result will be:
#
# <html>
# <body>
# <h1>Radius Example</h1>
# <ul class="hlist">
# <li>Hello, World!</li>
# <li>Hello, World!</li>
# <li>Hello, World!</li>
# </ul>
# Jackpot!
# </body>
# </html>
