λProlog: Logic programming in higher-order logic
Summary
λProlog is a logic programming language built on higher-order intuitionistic logic and HOAS, enabling modular programming, abstract datatypes, and higher-order syntax. The article catalogs main implementations (ELPI, Teyjus, Makam), key documentation, and notable tools like Abella, highlighting its use in meta-programming and theorem proving. It serves as a reference for researchers or developers exploring logic programming in AI contexts.
