Creates a new Parser object with the given TreeSitter\Grammar grammar. See built-in parser grammars in the Parsers section below.

Parses the source code and produces a TreeSitter\Tree instance or throws TreeSitter\SyntaxError exception.

Ouputs the S-expression syntax tree for the current node and its siblings.

The row within the source tree. See TreeSitter\Node::getStartPoint() and TreeSitter\Node::getEndPoint().
