Prolog has a built-in grammar mechanism, Definite Clause Grammars (DCGs). A DCG describes a sequence, and allows us to conveniently reason about sequences manifested as lists.

We use them for parsing, describing output, passing arguments implicitly, reading from files, and several other applications. More information: https://www.metalevel.at/prolog/dcg ...more
