I started reading the book, but there was a surprise in the form of diagrams. How to understand them?

    Imagine that this is the road you are driving. From left to right. Where it is smooth, you can roll it, where a sharp corner is not worth it. Sottvetstvenno folding in a circle, you can go, repeating the symbol. - Duck Learns to Take Cover

    In general (strictly IMHO) I would not steal with the understanding of these diagrams. You need to understand that this is just a visualization (rather unfortunate in my opinion) of the normal way of describing a certain type of grammar: Backus-Naur forms - Duck Learns to Take Cover

  • Everything related to the question should be in the question itself . Links can only serve as a supplement . - Dmitriy Simushev
