options(*new_options) click to toggle source

Allows defining convenience option accessors for an array of option names Example: `options :color1, :color2` defines `#color1` and `#color2` where they return the instance values `options` and `options` respectively. Can be called multiple times to set more options additively. When passed no arguments, it returns list of all option names captured so far

# File lib/glimmer/ui/custom_widget.rb, line 41
def options(*new_options)
  new_options = new_options.compact.map(&:to_s).map(&:to_sym)
  if new_options.empty?
    @options ||= {} # maps options to defaults
  else
    new_options = new_options.reduce({}) {|new_options_hash, new_option| new_options_hash.merge(new_option => nil)}
    @options = options.merge(new_options)
    def_option_attr_accessors(new_options)
  end
end
shortcut_keyword() click to toggle source

Returns shortcut keyword to use for this custom widget (keyword minus namespace)

# File lib/glimmer/ui/custom_widget.rb, line 92
def shortcut_keyword
  self.name.underscore.gsub('::', '__').split('__').last
end
