Sass makes CSS fun again. Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It's translated to well-formatted, standard CSS using the command line tool or a web-framework plugin. This is a repackaged GEM in a JAR format of the sass-lang.gem package. The sass-gems package version follows the sass-lang.gem versions located http://rubyforge.org/frs/?group_id=9702. Simply change the version of this package to download and repackage the same GEM version.

There is a newer version: 3.2.9

module Sass::Tree
  # A static node representing an unproccessed Sass `@`-directive.
  # Directives known to Sass, like `@for` and `@debug`,
  # are handled by their own nodes;
  # only CSS directives like `@media` and `@font-face` become {DirectiveNode}s.
  #
  # `@import` and `@charset` are special cases;
  # they become {ImportNode}s and {CharsetNode}s, respectively.
  #
  # @see Sass::Tree
  class DirectiveNode < Node
    # The text of the directive, `@` and all, with interpolation included.
    #
    # @return [Array]
    attr_accessor :value

    # The text of the directive after any interpolated SassScript has been resolved.
    # Only set once \{Tree::Visitors::Perform} has been run.
    #
    # @return [String]
    attr_accessor :resolved_value

    # @param value [Array] See \{#value}
