Ferret is a Lisp (Clojure-inspired) implementation that compiles down to self-contained C++11 code for real-time embedded control systems. Generated code runs on any platform with a C++11 compiler, from microcontrollers with 2KB of RAM to desktop operating systems.

Use cases

  • write embedded firmware in a lisp dialect
  • compile clojure-like code to c++11 for microcontrollers
  • run lisp on arduino or teensy boards
  • prototype real-time control systems in lisp
  • target atmega and arm chips with high-level code
  • generate portable c++ from lisp source

When to choose

  • you want lisp/clojure syntax for embedded or bare-metal targets
  • you need real-time behavior on resource-constrained microcontrollers
  • you want portable C++11 output rather than a VM interpreter

When to avoid

  • you need a full modern Clojure runtime or JVM ecosystem
  • you want an actively developed project with frequent releases
  • your target lacks a C++11 compliant compiler
