lazyprop / little-lisp

A little lisp interpreter written in Rust.

A little Lisp interpreter written in Rust. Implements a small subset of Scheme. Extremely slow, but works.

Small example:

To-do's for the next interpreter I write

• Because of the way built-in functions like arithmetic are represented in the codebase, they cannot be treated as normal lisp procedures. Trying to pass + into a fold, for example, will result in a name error.
• Too many clones and other hacks to get around Rust's ownership rules. This probably does significantly impact the execution speed of the compiler.
• Better, context-aware errors, errors at the parser level for catching syntax errors etc.
• Quotes.
• Tail call optimization.
