The Magic of Metalinguistic Programming: Simplifying Code with Interpreters
2025-01-01
This article explores the power of metalinguistic programming, specifically using interpreters to simplify complex code. The author uses Lisp expression simplification as an example, showing how building an 80-line Scheme interpreter and 30 rules can accomplish a task that would otherwise require thousands of lines of code. The key is shifting the programming paradigm to data-driven rule matching, avoiding significant code duplication. While not magic, the author argues this metalinguistic abstraction is a powerful tool worthy of further exploration.
