# Helper for producing Twitter Bootstrap labels.  We call them stamps because #label() is
# a Rails helper method.
#
# Default label:
#
#   stamp('Default')
#
# Other labels (see LABEL_TYPES):
#
#   stamp('Info', :info)
#
# Options passed through to <span> tag:
#
#   stamp('Warning', :warning, id: 'warn-id', class: 'more-class', my_key: 'my_value')
#
module Bootstrap::StampHelper
  InvalidStampTypeError = Class.new(StandardError)
  
  LABEL_TYPES = %w(default success warning important info inverse)
  
  # stamp('Text')
  # stamp('Text', :success)            # see LABEL_TYPES
  # stamp('Text', :info, id: 'my-id')  # options passed thru to <span>
  def stamp(*args)
    text = args.shift
    options = add_label_classes(*args)
    content_tag(:span, text, options)
