Developed at NASA’s Johnson Space Center from 1985 to 1996, the C Language Integrated Production System (CLIPS) is a rule‑based programming language useful for creating expert systems and other programs where a heuristic solution is easier to implement and maintain than an algorithmic solution. Written in C for portability, CLIPS can be installed and used on a wide variety of platforms. Since 1996, CLIPS has been available as public domain software.

CLIPS is a dynamic programming language that embodies the essence of a “higher level” language, providing a suite of tools that abstract away lower-level programming complexities. Originally designed for developing software that emulates human decision-making processes, CLIPS leverages rule-based logic akin to higher-level programming languages like Python, which simplify and enhance the developer’s capacity to manage complex functionalities without reinventing the wheel.

Key Features of CLIPS:
  • Automatic Caching for Common Conditions: CLIPS optimizes performance through automatic caching, similar to caching mechanisms in databases, which pre-fetch and index data to minimize repetitive processing and accelerate data retrieval.
  • Built-in Query Language: It includes Domain-Specific Languages (DSLs) for querying Instances and Facts, enabling sophisticated data manipulation and retrieval directly within the engine.
  • Optimization and Compilation: CLIPS allows the compilation of the rules engine into a single binary, enhancing execution speed and optimizing resource usage, which is critical in environments requiring high performance.

Practical Application and Benefits

Using CLIPS, developers can implement complex logic systems that are both scalable and efficient. Its rule-based structure, combined with procedural and object-oriented programming capabilities, makes it suitable for various applications, from AI in gaming to decision support systems in healthcare and operational management in aerospace.

The inherent capabilities of CLIPS to act as a rules engine with high-level programming features allow developers to write less code while achieving greater functionality. This mirrors the advantages seen in languages like Python, where the emphasis is on simplicity and readability, enabling programmers to focus more on solving the problem at hand rather than getting bogged down by the intricacies of the programming language itself.

This makes CLIPS an excellent choice for projects that aim to integrate sophisticated rule-based systems with the speed and performance of compiled languages.
