InlineParser constructor

InlineParser(String? source, Document document)

Implementation

  // User specified syntaxes are the first syntaxes to be evaluated.
  syntaxes.addAll(document.inlineSyntaxes);

      .any((s) => !document.extensionSet.inlineSyntaxes.contains(s));

  // This first RegExp matches plain text to accelerate parsing. It's written
  // so that it does not match any prefix of any following syntaxes. Most
  // Markdown is plain text, so it's faster to match one RegExp per 'word'
  // rather than fail to match all the following RegExps at each non-syntax
  // character position.
  if (hasCustomInlineSyntaxes) {
    // We should be less aggressive in blowing past "words".
    syntaxes.add(TextSyntax(r'[A-Za-z0-9]+(?=\s)'));
