Iterable<String> asDocumentationComments(
  Iterable<String> comments,
  DocumentCommentSpecification commentSpec, {
  List<String> generatorComments = const <String>[],
}) sync* {
  final List<String> allComments = <String>[
    ...comments,
    if (comments.isNotEmpty && generatorComments.isNotEmpty) '',
    ...generatorComments,
  ];
  String currentLineOpenToken = commentSpec.openCommentToken;
  if (allComments.length > 1) {
    if (commentSpec.closeCommentToken != '') {
      yield commentSpec.openCommentToken;
      currentLineOpenToken = commentSpec.blockContinuationToken;
    }
    for (String line in allComments) {
      if (line.isNotEmpty && line[0] != ' ') {
        line = ' $line';
      }
      yield '$currentLineOpenToken$line';
    }
    if (commentSpec.closeCommentToken != '') {
      yield commentSpec.closeCommentToken;
    }
  } else if (allComments.length == 1) {
    yield '$currentLineOpenToken${allComments.first}${commentSpec.closeCommentToken}';
