Ferret is a free software lisp implementation designed to be used in

real time embedded control systems. Ferret lisp compiles down to self

contained *C++11*. Generated code is portable between any Operating

System and/or Microcontroller that supports a *C++11* compliant

compiler. It has been verified to run on architectures ranging from

embedded systems with as little as *2KB of RAM* to general purpose

computers running Linux/Mac OS X/Windows.

This repository contains the Ferret compiler. For more information about Ferret, 

including downloads and documentation for the latest release, check

## Quick Start

Download latest Ferret release,

```bash

wget https://ferret-lang.org/builds/ferret.jar

```

A program that sums the first 5 positive numbers. 

```clojure

;;; lazy-sum.clj

(defn positive-numbers

  ([]

   (positive-numbers 1))

  ([n]

   (cons n (lazy-seq (positive-numbers (inc n))))))

(println (->> (positive-numbers)

              (take 5)

              (apply +)))

```

Compile to binary using,

```bash

$ java -jar ferret.jar -i lazy-sum.clj

$ g++ -std=c++11 -pthread lazy-sum.cpp

$ ./a.out

```
