What? Do you have any data you'd like to share?
I'm given to understand that e.g. the C++ compilers usually have a hand-coded, but AFAIUI that's mostly due to the complexity of actually parsing it (and fitting that into anything other than just raw code).

A common theme is that the parser generator does not provide you the tools to write the high quality error messages. Having used ANTLR and other tools, I believe it now that I'm trying to ship a real language.
- Quekid5 6y agoYou're talking about parser generators... the article is about parser combinators. Fully agreed that parser generators are often very limited and often require hacks to do anything non-trivial. (IME MegaParsec basically solves most of the issues.)
