Comment by recursivedoubts

absolute gem of a book, I use it for my compilers class:

https://grugbrain.dev/#grug-on-parsing

recursive descent parsing is simple, beautiful, intuitive, flexible, shows the correspondence between recursion and grammars and it's how most production compilers are built

this book is the best (and one of the only) books to cover it in depth

it belongs on every programmers shelf
