Nowadays I’ve heard recommended Crafting Interpreters. (https://craftinginterpreters.com)

The Nanopass paper link doesn’t work.

Compilers are broad enough that when someone recommends a "compiler book", it's rarely exactly the slice you wanted.

So this made me do a runnable cheat sheet for Crafting Interpreters. I keep parsing demonstrative, and the AST is a little more Lisp-y than the book's.

Disclaimer: it's meant to convey the essence of what you'll learn, it is NOT by any means a replacement for the book. I'd also describe the book as more of an experience (including some things Nystrom clearly enjoyed, like the visitor pattern) than a compilers manual. If anyone's interested, I can do a separate visitor-pattern cheat sheet too, also in Python.

I turned it into a 'public-facing artifact' from private scripts with an AI agent.

Crafting Interpreters is great, I wish it had a companion book that covered:

  - types and typing
  - optimization passes
  - object files, executables, libraries and linking

Then two of them would be sufficient for writing a compiler.

    Types and Programming Languages, Benjamin C Pierce

    Linkers and Loaders, John R Levine

      I've read Pierce. It's not a bad book, but less grounded than CI, which has an explicit "workmanlike" approach.

    This would be like asking for a book on designing grammar. It's just too disjoint of a field to have any kind of reasonable baseline, and it's drop dead easy to grok a basic one together. With those two things being equal, just like with grammar, the answer to this is any resource about implementing the language you're trying to ape.

      It's drop dead easy to grok a basic one together until you get to hairy stuff like overloading, lambdas and generics.

      The reasonable baseline would be something like Java 1. Scalars, arrays and classes. If I remember correctly, Lox even skips arrays as an exercise for the user.

Awesome course! finished it while i was doing my final CS year because I had to wait on a bunch of classes (and frankly had no one to talk to before classes). I haven't tried nanopass, but there's other links that work, so I'll give it a go.
