assertComplexSelector method

ComplexSelector assertComplexSelector({ String? name, bool allowParent = false, })

Parses this as a complex selector, in the same manner as the selector-parse() function.

Throws a SassScriptException if this isn't a type that can be parsed as a selector, or if parsing fails. If allowParent is true, this allows ParentSelectors. Otherwise, they're considered parse errors.

If this came from a function argument, name is the argument name (without the $). It's used for error reporting.

Implementation

ComplexSelector assertComplexSelector({
  String? name,
  bool allowParent = false,
}) {
  var string = _selectorString(name);
  try {
    return ComplexSelector.parse(string, allowParent: allowParent);
  } on SassFormatException catch (error, stackTrace) {
    // TODO(nweiz): colorize this if we're running in an environment where
    // that works.
    throwWithTrace(
      SassScriptException(error.toString().replaceFirst("Error: ", ""), name),
      error,
      stackTrace,
    );
  }
}
