Go Lisp

This is my implementation of a small, toy Lisp language written in Go. It is based off of Mary Rose Cook's Little Lisp.

Build

You will need a current version of Go (I developed using 1.12). You will also need to install NexThen run:

make build

This will create an executable called gl, which is the interpreter.

Usage

Pass the file name to the interpreter to run it:

gl hello.gl

Documentation

There isn't any official documentation since this is just a proof of concept project. But here's what's been implemented:

print

(print exp1 exp2 exp3)

This takes any number of arguments and prints them to stdout.

let

(let ((h 'hello')
      (w 'world'))
      (print h ' ' w))

Create a scope and declare variables within that scope.

if

(if exp
    trueExp
    falseExp)

Checks the boolean value of exp and executes trueExp if exp is true, otherwise it executes falseExp.

lambda

(lambda (x) (print x))

My lambda implementation is still pretty rough, but you can define small functions with ease.
