Prolog Coding Horror
The article 'Prolog Coding Horror' on metalevel.at catalogs typical mistakes in Prolog programming, drawing from real-world code and teaching experiences. Examples include using cut (!) to simulate if-then-else, which can prune valid solutions, and writing non-tail-recursive predicates that cause stack overflows for large inputs. The author highlights how Prolog's declarative nature is undermined by imperative thinking, leading to code that is hard to read and maintain. A concrete case shows a predicate intended to find all solutions but failing due to incorrect use of negation as failure. The piece serves as a cautionary guide for both new and experienced Prolog developers, emphasizing the need to embrace logic programming paradigms.
Avoiding these anti-patterns is crucial for writing reliable and maintainable Prolog code.
