By Paulo Moura, University of Beira Interior, Portugal

Logtalk is an object-oriented logic programming language that can use most Prolog implementations as a back-end compiler. As a multi-paradigm language, it includes support for both prototypes and classes, protocols (interfaces), component-based programming through category-based composition, event-driven programming, and high-level multi-threading programming.

This release implements a call//1 built-in non-terminal, changes the scope of the built-in methods phrase/2-3 for more consistent meta-predicate semantics, clarifies the scope of the term-expansion and goal-expansion mechanisms, fixes all known bugs, adds experimental on-line help support, adds man pages for all POSIX shell scripts, bundles Victor Lagerkvist’s Verdi Neruda (a meta-interpreter collection that includes both top-down and bottom-up search strategies), and includes portability updates for Ciao Prolog, ECLiPSe, Qu-Prolog, SWI-Prolog, XSB, and YAP.
