resolved_value[RW]

The text of the comment after any interpolated SassScript has been resolved. Only set once {Tree::Visitors::Perform} has been run.

@return [String]

type[RW]

The type of the comment. `:silent` means it's never output to CSS, `:normal` means it's output in every compile mode except `:compressed`, and `:loud` means it's output even in `:compressed`.

@return [Symbol]

value[RW]

The text of the comment, not including ` ` and ` `. Interspersed with {Sass::Script::Node}s representing `#{}`-interpolation if this is a loud comment.

@return [Array<String, Sass::Script::Node>]

@param value [Array<String, Sass::Script::Node>] See {#value} @param type [Symbol] See {#type}

Calls superclass method

    # File lib/sass/tree/comment_node.rb, line 31
    def initialize(value, type)
      @value = Sass::Util.with_extracted_values(value) {|str| normalize_indentation str}
      @type = type
      super()
    end

### Public Instance Methods

==(other) click to toggle source

Compares the contents of two comments.

@param other [Object] The object to compare with @return [Boolean] Whether or not this node and the other object

    are the same

    # File lib/sass/tree/comment_node.rb, line 42
    def ==(other)
      self.class == other.class && value == other.value && type == other.type
    end

invisible?() click to toggle source

Returns `true` if this is a silent comment or the current style doesn't render comments.

Comments starting with ! are never invisible (and the ! is removed from the output.)

@return [Boolean]

    # File lib/sass/tree/comment_node.rb, line 52
    def invisible?
      case @type
      when :loud; false
      when :silent; true
      else; style == :compressed
      end
    end

lines() click to toggle source

Returns the number of lines in the comment.

@return [Fixnum]

    # File lib/sass/tree/comment_node.rb, line 63
    def lines
      @value.inject(0) do |s, e|
        next s + e.count("\n") if e.is_a?(String)
        next s
      end
    end
