Gambit (Scheme implementation)

Gambit, also called Gambit-C, is a free software Scheme implementation, consisting of a Scheme interpreter, and a compiler which compiles Scheme to C. Its documentation claims conformance to the R⁴RS, R⁵RS, and IEEE standards, as well as several SRFIs. Gambit was first released 1988, and Gambit-C (that is, Gambit with the C backend) was first released 1994.

Termite Scheme is a variant of Scheme implemented on top of Gambit-C. Termite is intended for distributed computing, it offers a simple and powerful message-passing model of concurrency, inspired by that of Erlang.

While the compiler itself produces solely C code, it has full integration support for C++ and Objective-C compilers such as GCC. Thus, software written in Gambit-C can contain C++ or Objective-C code, and can fully integrate with corresponding libraries.
