About:
Logtalk is a declarative object-oriented logic programming language designed for modern software development. It seamlessly integrates with Prolog implementations, enabling developers to build robust, modular, and scalable applications. Its key value lies in providing advanced code reuse and concurrency features, making complex software engineering manageable within a logic programming paradigm.

Key Features:

Object-oriented programming on top of Prolog
Parametric objects and categories for fine-grained code reuse
Built-in support for multi-threading and concurrency
Extensive compiler and linter flags for code quality
Portable across most ISO Prolog systems

Use Cases:

Building expert systems and AI applications
Developing complex rule-based business logic
Scientific modeling and computational research
Educational tool for teaching advanced logic programming concepts

Alternatives:

Prolog – Logtalk extends standard Prolog with modern OOP features like classes and prototypes, whereas vanilla Prolog is primarily procedural/module-based.
