This project is a Lisp interpreter implementation guide and framework designed to teach the core principles of programming language design. It provides a structured, step-by-step technical framework for building a functional Lisp language from scratch, featuring a specialized interpreter engine and an S-expression parser that converts syntax into abstract syntax trees.
The project emphasizes a code-as-data metaprogramming framework, enabling the implementation of macros, quoting, and quasiquoting to transform expressions during evaluation. It is designed with host language agnosticism, allowing the interpreter logic to be implemented across diverse programming languages and runtimes.
The implementation covers a broad range of language capabilities, including lexical scope management, tail-call optimization to prevent stack overflow, and a host-language bridge for interoperability. It includes developer tooling such as a programmable read-eval-print loop for real-time execution in consoles or web browsers, as well as a functional test harness for implementation verification.
