What's Gambit?
Gambit consists of two main programs: gsi, the Gambit Scheme interpreter, and gsc, the Gambit Scheme compiler. The interpreter contains the complete execution and debugging environment. The compiler is the interpreter extended with the capability of generating executable files. The compiler can produce standalone executables or compiled modules which can be loaded at run time. Interpreted code and compiled code can be freely mixed.
Gambit-C is a version of the Gambit programming system in which the compiler generates portable C code. The main features of Gambit-C are:
- Conformance. The Gambit-C system conforms to the R4RS, R5RS and IEEE Scheme standards and implements all optional features. Tail calls and first class continuations conform to the Scheme semantics. The full numeric tower is implemented, including: arbitrary precision integers (bignums), rationals, inexact reals (floating point numbers), and complex numbers. Several extensions to Scheme are provided, including: lightweight threads, a foreign-function interface (FFI), and extended I/O capabilities (Unicode, networking, subprocesses, ...).
- Portability. Because the system is mostly written in Scheme and the compiler generates portable C code, it is easy to port the system as well as programs compiled with it to any platform with a decent C or C++ compiler. There is no reliance on a particular C compiler, although the system can take advantage of some gcc-specific constructs. The C code generated is oblivious to the endianness and word size of the target environment (32 and 64 bit architectures are currently supported). There are no external library dependencies, and OS API dependencies can be removed so as to run directly on the bare metal. The system includes high-performance bignum support utilizing sophisticated algorithms, implemented in Scheme.
- Performance. The compiler includes several powerful program transformations such as user procedure inlining, partial-evaluation, and lambda-lifting. With appropriate declarations in the source code the executable programs generated by the compiler run roughly as fast as equivalent C programs. Programs containing no declarations are also optimized without compromising the Scheme semantics by speculatively inlining predefined procedures (see the benchmarks page for a comparison with other Scheme implementations and other languages). Thanks to an efficient implementation of continuations, the thread system is very efficient and can support millions of concurrent threads.
- Reliability. Stable releases typically have very few bugs. Bug tracking is done with the issue tracker on github. Gambit-C has been used to develop large-scale real-world software and services in academic and commercial settings.
An overview of the Gambit system was presented by Marc Feeley at the 2010 International Lisp Conference. The slides of the "Gambit Scheme: Inside Out" talk are here. The slides for the talk "Compiling for Multi-language Task Migration" given at DLS 15 are here. The slides for the talk "Tail Calling Between Code Generated by C and Native Backends" given at the Scheme Workshop 2018 are here.
Getting Gambit
Gambit is available as prebuilt and source code distributions. There are prebuilt distributions for Mac OS X, iPhone/iPod touch/iPad (on Apple App Store), Microsoft Windows, and other operating systems. The source code distributions must be compiled with a C or C++ compiler. The latest sources are available at the Gambit repo on github.
