  The parsers in crafting interpreters do not use the visitor pattern. The visitor pattern is used when you already have a tree structure or similar. The parser is what gives you such tree structure, the AST. When you have this structure, you typically use the visitor pattern to process it for semantic analysis, code generation, etc.
