How to make Flexmark-Java process "@"-mentions?

在处理 markdown 时,GitHub 支持 @-syntax 到 mention a username or team。如何使用 Flexmark-Java 处理此类提及?使用以下代码片段,Hello, @world ! 被报告为单个 Text 节点,我希望将 world 单独报告为某种 MentionsNode

final Parser parser = Parser.builder(new Parser.Builder()).build();
final Document document = parser.parse("Hello, @world !");
new NodeVisitor(Collections.emptyList()) {
       public void visit(Node node) {
           System.out.println("Node: " + node);
           super.visit(node);
       }
   }.visit(document);

输出:

Node: Document{}
Node: Paragraph{}
Node: Text{text=Hello, @world !}

这个有相应的扩展:

final MutableDataHolder options = new MutableDataSet()
                .set(Parser.EXTENSIONS, Collections.singletonList(GfmUsersExtension.create()));
final Parser parser = Parser.builder(options).build();
final Document document = parser.parse("Hello, @world, and #1!");
