# Automatically adds css classes to input tags so that fields can be
# easily styled.
# 
# == Tag examples
#   
#   text_field_tag('name')        # => <input class="text" id="name" name="name" type="text" />
#   hidden_field_tag('name')      # => <input class="hidden" id="name" name="name" type="hidden" />
#   radio_button_tag('agree', 1)  # => <input class="radio" id="agree_1" name="agree" type="radio" value="1" />
# 
# == Form helper examples
# 
#   text_field(:person, :name)        # => <input class="text" id="person_name" name="person[name]" size="30" type="text" />
#   hidden_field(:person, :name)      # => <input class="hidden" id="person_name" name="person[name]" type="hidden" />
#   radio_button(:person, :agree, 1)  # => <input class="radio" id="person_agree_1" name="person[agree]" type="radio" value="1" />
# 
# == Merging options
# 
# If you specify additional classes when creating a tag, the automated css
# classes will be prepended to the current ones.  For example,
# 
#   text_field_tag('name', :class => 'selected')        # => <input class="text selected" id="name" name="name" type="text" />
#   text_field_tag('name', :class => 'selected shadow') # => <input class="text selected shadow" id="name" name="name" type="text" />
module StyledInputs
  # Appends the input type to the value currently stored in the html options
  # for the tag.
  def styled_input(name, options = nil)
    options = (options || {}).stringify_keys
    
    if name.to_s == 'input' && options.include?('type')
      options['class'] = (options['class'].to_s + " #{options['type']}").strip
    end
