parse method

Resource parse(String source)

Parse the full source into a Resource.

Implementation

Resource parse(String source) {
  final ps = FluentParserStream(source);
  ps.skipBlankBlock();

    // line. If the comment is followed by junk or by blank lines, it stays
    // a standalone Comment entry.
    if (entry is Comment &&
        entry.level == CommentLevel.regular &&
        blankLines.isEmpty &&
        ps.currentChar() != eof) {
