StringDumperVisitor

To easily debug the structure and capture AST structure, you can use the StringDumperVisitor visitor.

use TypeLang\Parser\Traverser;

$visitor = new Traverser\StringDumperVisitor();

Traverser::new([$visitor])
    ->traverse([$result]);

echo $visitor->getOutput();

tip

You can see the following text as the output result:

Stmt\NamedTypeNode
  Name(array)
  Stmt\Template\ArgumentsListNode
    Stmt\Template\ArgumentNode
      Stmt\NamedTypeNode
        Name(array-key)
    Stmt\Template\ArgumentNode
      Stmt\NamedTypeNode
        Name(object)
        Stmt\Shape\FieldsListNode(unsealed)
          Stmt\Shape\NamedFieldNode(required)
            Stmt\NamedTypeNode
              Name(int)
              Stmt\Template\ArgumentsListNode
                Stmt\Template\ArgumentNode
                  Literal\IntLiteralNode(0)
                Stmt\Template\ArgumentNode
                  Stmt\NamedTypeNode
                    Name(max)
