  } else {
    option = completionLevel.grammar.findByNameOrAlias(optionName);
  }

  final allowed = option?.allowed ?? [];
  Iterable<String> filteredAllowed;
  if (pattern == null) {
    filteredAllowed = allowed;
  } else {
    filteredAllowed = allowed.where((e) => e.startsWith(pattern!));
  }
  return {
    for (final allowed in filteredAllowed)
      if (includeAbbrName)
        '-$optionName$allowed': option?.allowedHelp?[allowed]
