Ferret

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 out Ferret's website
