SWI-Prolog (SWIPL) is a free and open-source command line tool for the Prolog programming language. It provides a powerful environment for developing and executing Prolog programs.

SWIPL supports a wide range of platforms including Windows, macOS, and various Unix-like systems. It is known for its compatibility with ISO-Prolog standards, making it highly reliable for cross-platform development.

The tool offers an interactive read-eval-print loop (REPL), where users can enter Prolog queries and see the results immediately. It supports tab completion, history navigation, and syntax highlighting, which enhance the development experience.

SWIPL provides a comprehensive library of built-in predicates and modules for various tasks such as file handling, network programming, and GUI development. This makes it very versatile and suitable for a range of applications.

The tool includes an integrated development environment (IDE) called SWI-Prolog Development Environment (SWI-Prolog IDE) that provides advanced features like code navigation, debugging, profiling, and automatic documentation generation.

SWIPL also supports multithreading and concurrency, allowing concurrent execution of Prolog predicates and parallel computing.

It has a built-in foreign language interface, which enables developers to interface Prolog with C, Java, or other languages. This makes it possible to use external libraries and resources within Prolog programs.

SWIPL is widely used in academia and industry for tasks such as artificial intelligence, natural language processing, knowledge representation, and expert systems.

It has an active and supportive user community, which constantly contributes to the improvement and extension of the tool through bug fixes, updates, and user-friendly documentation.

Overall, SWIPL is a powerful and user-friendly command line tool that provides a rich development environment for Prolog programmers, enabling them to build complex and intelligent applications.
