Hedgehog

Yet another Lisp dialect+implementation.

From the website:

  • Hedgehog is a very concise implementation of a Lisp-like language for low-end and embedded devices. It consists of a compiler and a byte code interpreter. The byte code interpreter is written in standard conforming C, is efficient and easily portable, and can be compiled to a very small executable of only some 20 kilobytes in the smallest configuration for the Intel x86 architecture.

  • The Hedgehog Lisp dialect has proper support for local and lambda functions, lexical scoping, variable argument functions, garbage collection, exceptions, macros, and over a hundred predefined functions or special forms. The built-in types are lists, symbols, strings, 32-bit integers, AVL-trees, and tuples up to 16 elements wide. Proper 32-bit wide integers are necessary for various bit-level operations in embedded systems.


A paper and a set of slides describing the implementation is also available.
