I just made a toy programming language based on Lisp

faraazahmad / tisp

A toy programming language based on Lisp and built in Rust & LLVM

Tisp (Toy Lisp)

A Lisp-like programming language that is typed and compiled. It aims to support multiple processor architectures by being built upon LLVM. It takes inspiration from programming languages like Rust, Lisp and Elixir.

Current working example

A program to compute first 5 fibonacci numbers:

(let first 0)
(let second 1)
(let fib)
(let n 0)
(while (< n 5)
    (let fib (+ first second))
    (let second first)
    (let first fib)
    (let n (+ n 1))
    (print fib)
)

Features to build

• Convert raw code into token stream
• Convert token stream into Expression tree
• Handle multiple levels of nested expressions
• Have multiple (independent) expressions per file
• Generate LLVM IR for the currently supported features
• add CLI flag to emit llvm
• add while loop
• Declare variables
• add nested while loops
• Add types for…

Made a post about it if you're interested

I was bored, so I built a programming language
