Yes, it walks your through it step by step. I have https://pragprog.com/titles/tpantlr2/the-definitive-antlr-4-reference/ https://pragprog.com/titles/tpantlr2/the-definitive-antlr-4-... and at least 1 more of his, forget where it is. I would say it is ageless (at least, until something better than ANTLR comes along—ohm is promising but not sure what the latest is with that). "The Definitive ANTLR 4 Reference" is absolutely the most understated title I've ever seen in a book. It's really more like "The Book That Will Change How you Look at Programming Languages Forever" IMO anyway. I guess it depends on how much you've been exposed to parsers and grammars and compiler compilers already.
