A community for discussing the Logtalk programming language. From the web site: > Logtalk is a declarative object-oriented logic programming language that extends and leverages the Prolog language with modern code encapsulation and code reuse mechanisms while also providing improved predicate semantics. Backed by a variety of popular Prolog back-ends, it is easy for Prolog programmers to get to learn ranging from using it as a sound module system (replacing the unsound module systems typically used in Prologs) to a full-fledged software engineering language incorporating modules, prototypes, classes, protocols, categories, threads, and events, among many other features, into a coherent, well-documented whole that is oozing with examples to illustrate concepts in action as well as practical uses.
