OpenMCL

OpenMCL is a Common Lisp implementation. It began as a subset of the commercial MCL (Macintosh Common Lisp), and has grown into a full-featured, stable implementation. All of OpenMCL is released under the GNU Lesser General Public License. Commercial MCL does have a nicely integrated IDE and user interface libraries, which were not open-sourced and are not available in OpenMCL.

Note that OpenMCL runs on more systems than just the Macintosh. There are ports to 32/64-bit Darwin/PPC, 32/64-bit Linux/PPC, 64-bit Linux/X86, 64-bit Darwin/X86, and 64-bit FreeBSD/X86.

OpenMCL is maintained by Gary Byers of Clozure Associates, formed by the original developers of MCL. Clozure also offers commercial support and consulting for OpenMCL projects.

The strong points of OpenMCL are:

full source code under LGPL
compile everything strategy, even for code typed to a listener
fast native code compiler
small footprint
fast garbage collection
ephemeral garbage collection for short lived objects
supports threads and multiple Lisp listeners
OS level threading (v 0.14)
support for TCP and UDP via "sockets"
can compile itself quite quickly
based on a mature Lisp implementation (MCL) that was created more than fifteen years ago
native CLOS implementation with very complete MOP support and "primary classes"
can dump Lisp "images" with preloaded code and data
comfortable FFI for integrating foreign code
interface database holding information about foreign functions and data types
FFI bindings for Unix libc, Carbon, Cocoa
lisp routines are callable from foreign code
integrated assembler ("LAP") with support for the Altivec engine found in the PowerPC G4
now runs on MacOS X
ANSI Common Lisp
Works with SLIME and ILISP

Mikel Evins has released Bosco, a "simple template for building Cocoa applications in OpenMCL." It is released under the LLGPL.

Sven Van Caekenberghe has released a full implementation of the XML-RPC protocol for OpenMCL. It is released under the LLGPL. Portable AllegroServe is used for the server side.

Documentation, source and binaries are available from the Clozure website.

OpenMCL is available in Fink or DarwinPorts packages. There is also a package for CLX (openmcl-clx) available through Fink.

OpenMCL is extremely cool - check it out! (Rainer Joswig)

Recently (summer 2004), the documentation for OpenMCL has been taken over by Dan Knapp. It has been edited together into a web-book, with the emphasis being on making things easy to find.
