# Lisp interpreter

Lisp interpreter implementation in Pharo.

Creating an interpreter:

```smalltalk

lisp := Lisp scheme.

```

Lambda definitions:

```smalltalk

lisp evaluate: #(define factorial (lambda (n)

	(if (= n 1)

		 1

		 (* n (factorial (- n 1) ))))).

		

lisp evaluate: #(define map (lambda (f list)

	(if (#'null?' list)

		 nil

		 (cons (f (car list)) (map f (cdr list)))))).

lisp evaluate: #(define double (lambda (n) (* 2 n))).

lisp evaluate: #(map double (cons 1 (cons 2 (cons 3 nil)))).

```

Function definitions.

```smalltalk

lisp evaluate: #(define (factorial n)

	(if (= n 1)

		 1

		 (* n (factorial (- n 1) )))).

lisp evaluate: #(factorial 5).

```
