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.

Constructor Details

#initialize(*args) ⇒ Declarations

The allowed format is any string consisting only of whitespace characters, including newline. The default format string is a single space, which is probably the most common choice in hand-written CSS.

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(@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.
