Hello.
I have seen that there is an offer at Packt Publishing where they offer all their books and videos for 5 euros. I have bought several videos by author Dmitry Soshnikov, on building a parser from scratch, algorithms for parsers, creating an interpreter from scratch, garbage collection algorithms, state machines and automata for building regular expressions:
Or a book on how to build your own language: Build Your Own Programming Language | Packt
On the page Compiler Engineer Path – Dmitry Soshnikov, the author suggests which is the order he considers appropriate to follow the courses.
