hello list, I am currently reading Language Implementation Patterns and I'm quite confused by ASTs in chapter 4 and 5. This is what's happening.
Chapter 4 talked about Parse Trees and ASTs. Parse Trees were constructed by adding tree-construction statements to parsing rules. But ASTs were constructed manually. So when I got to chapter 5 and I wanted to implement a visitor for my tree I got stuck. I'm sorry I can't use the examples; I had to translate every example to Python, the language I use. I don't really know how and most importantly when to construct the AST. The book does not say it precisely. I'm thinking if it's done during parsing, isn't it really a Parse Tree?
