the dragon book is how to write a production grade thing i guess. it has all the interesting concepts very elaborated on which is great but it dives quickly into things that can clutter a project if its just for fun..

It’s academic and comprehensive, that’s the issue. It’s not about writing a production grade compiler, though, in my humble opinion. There are more things to learn for that, unfortunately… is just a pretty big topic with lots of stuff to learn.
