Examples:

Basic usage in template

require 'hanami'

module Web::Views::Home
  class Index
    include Web::View
  end
end

# ERB template
# <%= routes.home_path %>

Basic usage in view

require 'hanami'

module Web::Views::Home
  class Index
    include Web::View

    def link_to_home
      %(<a href="#{ routes.home_path }">Home</a>)
    end
  end
end

# ERB template
# <%= link_to_home %>
