Lispico

Lispico is a functional, Lisp-like programming language. It is designed to be minimalist and elegant, while still being pragmatic, flexible and useful.

This repository contains the source code for a Lispico interpreter written in Rust.

Note: This project is a work in progress, see Roadmap section below.

Key Characteristics

• Functional - Lispico is a functional language, meaning that functions are first-class citizens and all values are immutable.
• Code-Data Interchangeability - All programs are data, and any value is a syntactically correct program.
• Minimalist - Minimal amount of syntax rules and no keywords at all.

Installation and Usage

Note: You must have git and Rust installed to run Lispico.

To start the Lispico interpreter, clone the repository and run the project using Cargo:

git clone https://github.com/AdiHarif/lispico.git
cd lispico
cargo run

You can now start writing Lispico code in the REPL - each expression entered will be evaluated and the evaluation result will be printed:

$ (. 'a '(b c))
(a b c)

$ (.< '(a b c))
a

$ (? x 'a 'b)
b

$ (:= x 't)
$ (? x 'a 'b)
a
