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 [https://github.com/gambit/gambit/issues issue tracker on github]. Gambit-C has been used to develop large-scale [[Real-world software and services | real-world software and services]] in academic and commercial settings. An overview of the Gambit system was presented by Marc Feeley at the [http://www.international-lisp-conference.org/2010/index 2010 International Lisp Conference].

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 [https://github.com/gambit/gambit Gambit repo on github]. ==Documentation== [[Documentation]] is available. ==Contributing== Learn [[how to contribute]] to Gambit's development. ===Reporting bugs=== Please use the [https://github.com/gambit/gambit/issues issue tracker on github]. Note that the bugzilla bug tracker previously used ([http://www.iro.umontreal.ca/~gambit/bugzilla/ Gambit bugzilla bug tracker]) will be phased out in favour of the github issue tracker. ===Source repository=== [https://github.com/gambit/gambit Gambit repo on github] ==License== Gambit is Copyright &copy; 1994-2020 by Marc Feeley.
