glyph icon helper for twitter-bootstrap with Rails

application_helper.rb

module ApplicationHelper
  # ==== Examples
  # glyph(:share_alt)
  # # => <i class="icon-share-alt"></i>
  # glyph(:lock, :white)
  # # => <i class="icon-lock icon-white"></i>

  def glyph(*names)
    content_tag :i, nil, class: names.map{|name| "icon-#{name.to_s.gsub('_','-')}" }
  end
end

works wonderfully!

<%= link_to glyph(:pencil) + ' Edit profile', edit_user_registration_path %>
<%= link_to  glyph(:"warning-sign") + " Logout", destroy_user_session_path, method: :delete %>

Thanks, this helped me a lot!
