CHICKEN is a compiler for the Scheme programming language. CHICKEN produces portable, efficient C, supports almost all of the current Scheme language standard, R5RS and includes many enhancements and extensions. CHICKEN runs on MacOS X, Windows, and many Unix flavours.
FEATURES
- Includes a full-featured interactive interpreter as well as an optimizing batch compiler
- Full support for tail recursion, first-class continuations and high-level macros
- Highly portable and known to run on many platforms, including x86, x86-64, IA-64, PowerPC, SPARC and UltraSPARC, Alpha, MIPS,
PA-RISC, ARM and S/390
- Distributed free for use and modification under the terms of the BSD License
- Transparent support for dynamically loadable compiled code and linkage to C
- A sophisticated but easy to use foreign function interface for accessing C and C++ libraries from Scheme code
- Lightweight threads based on first-class continuations
- An object system with multiple dispatch, multiple inheritance and meta-object protocol
- Provides the syntax-case enhanced high-level macro system (including R5RS syntax-rules), and
define-macro style low-level macros
- Support for syntactic pattern-matching via Andrew Wright's match package
- Execution profiling, debugging, backtrace and single-stepping support
- A POSIX interface that covers environment and filesystem access, pipes, processes, signals, locks, sockets, and low-level and memory-mapped I/O
- Perl compatible regular expressions
- Support for interpreted or compiled shell scripts under Unix and Windows
- CHICKEN is supported by SWIG so interfacing to C or C++ can be automated
- Support for a large number of Scheme Requests For Implementation (SRFIs)
- Many libraries and extensions are available at "Eggs unlimited"
