Instance Attribute Details
- (Boolean) group_end
Whether or not this rule is the last rule in a nested group. This is only set in a CSS tree.
| 54 55 56 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 54
def group_end
  @group_end
end | 
- (Selector::CommaSequence) parsed_rules
The CSS selector for this rule, without any unresolved interpolation but with parent references still intact. It’s only guaranteed to be set once Visitors::Perform has been run, but it may be set before then for optimization reasons.
| 25 26 27 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 25
def parsed_rules
  @parsed_rules
end | 
- (Selector::CommaSequence) resolved_rules
The CSS selector for this rule, without any unresolved interpolation or parent references. It’s only set once Visitors::Perform has been run.
| 32 33 34 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 32
def resolved_rules
  @resolved_rules
end | 
- (Array<String, Sass::Script::Tree::Node>) rule
The CSS selector for this rule, interspersed with Script::Tree::Nodes representing #{}-interpolation. Any adjacent strings will be merged together.
| 17 18 19 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 17
def rule
  @rule
end | 
- (Sass::Source::Range) selector_source_range
The entire selector source range for this rule.
| 48 49 50 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 48
def selector_source_range
  @selector_source_range
end | 
- (String) stack_trace
The stack trace. This is only readable in a CSS tree as it is written during the perform step and only when the :trace_selectors option is set.
| 61 62 63 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 61
def stack_trace
  @stack_trace
end | 
- (Fixnum) tabs
How deep this rule is indented relative to a base-level rule. This is only greater than 0 in the case that:
- This node is in a CSS tree
- The style is :nested
- This is a child rule of another rule
- The parent rule has properties, and thus will be rendered

Instance Method Details
- (Boolean) ==(other)
Compares the contents of two rules.
| 97 98 99 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 97
def ==(other)
  self.class == other.class && rule == other.rule && super
end | 
- add_rules(node)
Adds another Sass::Tree::RuleNode‘s rules to this one’s.
| 104 105 106 107 108 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 104
def add_rules(node)
  @rule = Sass::Util.strip_string_array(
    Sass::Util.merge_adjacent_strings(@rule + ["\n"] + node.rule))
  try_to_parse_non_interpolated_rules
end | 
- (Boolean) continued?
Returns Whether or not this rule is continued on the next line
| 111 112 113 114 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 111
def continued?
  last = @rule.last
  last.is_a?(String) && last[-1] == ?,
end | 
- ({#to_s => #to_s}) debug_info
A hash that will be associated with this rule in the CSS document if the :debug_info option is enabled. This data is used by e.g. the FireSass Firebug extension.
| 122 123 124 125 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 122
def debug_info
  {:filename => filename && ("file://" + Sass::Util.escape_uri(File.expand_path(filename))),
   :line => line}
end | 
- filename=(filename)
If we’ve precached the parsed selector, set the filename on it, too.
| 87 88 89 90 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 87
def filename=(filename)
  @parsed_rules.filename = filename if @parsed_rules
  super
end | 
- (Boolean) invisible?
A rule node is invisible if it has only placeholder selectors.
| 128 129 130 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 128
def invisible?
  resolved_rules.members.all? {|seq| seq.has_placeholder?}
end | 
- line=(line)
If we’ve precached the parsed selector, set the line on it, too.
| 81 82 83 84 | # File '/Users/ceppstei/Projects/sass-lang/.sass/lib/sass/tree/rule_node.rb', line 81
def line=(line)
  @parsed_rules.line = line if @parsed_rules
  super
