Bob Nystrom is the author of Crafting Interpreters. I speak with Nystrom about building a programming language and an interpreter implementation for it. We talk about parsing, the difference between compiler and interpreters and a lot more. If you are wondering why many languages have hand-rolled parser implementations yet much work on build language implementations focuses on parser and tokenizer generators then Bob's insights will be eye-opening. Also, if you've ever used regexes to pull strings apart into structured data, and I sure have, then Bob's perspective on the simplicity of hand-rolled parsers will certainly open up some new possibilities for you.
