Best resources for learning about commercial “IDE grade” parsers
The fact that neither the traditional CS curriculum nor the research literature covers "real world, production-grade" parsers - especially ones suitable for use in commercial IDEs - has come up repeatedly on HN. That begs the question: are there resources that do? This is not a question about how lexing and parsing works, the merits of parser generators and specific grammars, the implementation of canonical parsers, or codebase examples, e.g., JetBrains community edition. It is a question about design patterns for practical concerns like evolution and maintainability, generating great error messages, operating incrementally, and remaining snappy when used on real (not pathological) PL sources. Thanks!
I think "Parsing Techniques" by Grune & Jacobs is the bible when it comes to parsing, it covers all subjects you mentioned and gives a detailed overview of most practical parsing approaches.
Engineering: A Compiler covers the issues you mention, but it is part of at least some CS curricula so I'm not sure it's what you're looking for.
Have you looked into any open-source language servers?
I wonder what your expectations are. Why would commercial IDEs not use the same methods of lexing and parsing as research products?
