parse method

MdcDocument parse(String source)

Parses source.

A YAML mapping fenced by --- at the beginning of the source becomes MdcDocument.frontmatter. Raw HTML remains text and is never interpreted by the parser.

Implementation

MdcDocument parse(String source) {
  final (:body, :frontmatter) = _readFrontmatter(source);
  final nodes = parseMdcBody(body);
  late MdcDocument document;
  try {
    document = MdcDocument(nodes: nodes, frontmatter: frontmatter);
  } on ArgumentError catch (error) {
    throw FormatException('Invalid MDC frontmatter: ${error.message}');
  } on TypeError {
    throw const FormatException('MDC frontmatter keys must be strings.');
  }
  for (final transform in transforms) {
    document = transform(document);
  }
  return headingIds ? document.withHeadingIds() : document;
}
