Overview

Declarations subclasses Array so that whenever #join is called, the instance’s format attribute will be used as the join string, rather than the empty string.

Instance Method Details

#join ⇒ Object

The format attribute is always used as the separator when joining the elements of a Declarations object.

def join
  super(self.class.format)
end

#to_s(symbols = {}) ⇒ Object

Returns a string by converting each element to a string, separated by the format attribute. Assuming that its contents are indeed Declaration objects, this will invoke their own #to_s method and generating correct CSS code.
