common-lisp CMUCL is a free implementation of the Common Lisp programming language which runs on most major Unix platforms. It mainly conforms to the ANSI Common Lisp standard. Here is a summary of its main features: * a sophisticated native-code compiler which is capable of powerful type inferences, and generates code competitive in speed with C compilers. * generational garbage collection and multiprocessing capability on the x86 ports. * a foreign function interface which allows interfacing with C code and system libraries, including shared libraries on most platforms, and direct access to Unix system calls. * support for interprocess communication and remote procedure calls. * an implementation of CLOS, the Common Lisp Object System, which includes multimethods and a metaobject protocol. * a graphical source-level debugger using a Motif interface, and a code profiler.
