Overview

Instance Attribute Summary

• - (Array<String, Sass::Script::Node>) name The name of the property, interspersed with Sass::Script::Nodes representing #{}-interpolation.
• - (String) resolved_name The name of the property after any interpolated SassScript has been resolved.
• - (String) resolved_value The value of the property after any interpolated SassScript has been resolved.
• - (Fixnum) tabs How deep this property is indented relative to a normal property.
• - (Sass::Script::Node) value The value of the property.

Instance Method Summary

• - (Boolean) =(other) Compares the names and values of two properties.
• - _cssize(extends, parent) protected Converts nested properties into flat properties.
• - (String) _to_s(tabs) protected Computes the CSS for the property.
• - cssize!(extends, parent) protected Updates the name and indentation of this node based on the parent name and nesting level.
• - (PropNode) initialize(name, value, prop_syntax) constructor A new instance of PropNode.
• - (String) invalid_child?(child) protected Returns an error message if the given child node is invalid, and false otherwise.
• - perform!(environment) protected Runs any SassScript that may be embedded in the property, and invludes the parent property, if any.
