Instance Method Details

#include_set(set, opts = {}) ⇒ Object

include a set module and all its format modules

Examples:

include_set Type::Basic, except: :css

pass an option

include_set Type::Name, default_name: "Luke"
default_name           # => "Luke"

def introduce_yourself
  puts my_name_is      # => "Luke"
end

# in Type::Name
def self.included host_class
  host_class.class_eval do
    define_method :my_name_is do |name=nil|
      name || host_class.default_name
    end
  end
end

Parameters:

  • set (Module)
  • opts (Hash) (defaults to: {}) —

    choose the formats you want to include. You can also pass arbitrary options to the included set. The option is saved in the including set. To use the option you need a ‘included` method in the included set to fetch the option.

Options Hash (opts):

  • :only (Symbol, Array<Symbol>) —

    include only these formats

  • :except (Symbol, Array<Symbol>) —

    don’t include these formats
