Welcome to the CMUCL Trac
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:
- support for static arrays that are never moved by GC but are properly removed when no longer referenced.
- Unicode support, including many of the most common external formats such as UTF-8 and support for handling Unix, DOS, and Mac end-of-line schemes.
- native double-double floats including complex double-double floats and specialized arrays for double-double floats and and complex double-double floats that give approximately 106 bits (32 digits) of precision.
- a sophisticated native-code compiler which is capable of powerful type inferences, and generates code competitive in speed with C compilers.
- generational garbage collection on all supported architectures.
- 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.
- an interface to the X11 Window System (CLX), and a sophisticated graphical widget library (Garnet).
- programmer-extensible input and output streams (Gray streams and simple-streams).
- an Emacs-like editor, Hemlock, implemented in Common Lisp.
- freely redistributable: free, with full source code (most of which is in the public domain) and no strings attached (and no warranty). Like the GNU/Linux and *BSD operating systems, CMUCL is maintained and improved by a team of volunteers collaborating over the Internet.
- ASDF 3.1.4.
- Fixed issue where TIME returned negative cycles on ppc.
- :UTF is no longer an alias for :UTF-8 for external formats.
- Motifd works as a 64-bit binary (thanks to Richard Kreuter)
- NetBSD updated to support 64-bit time_t and related values (from Robert Swindells).
A cross-compile on Darwin/x86 is needed for this release. (To get an updated and corrected EXTERN-ALIEN-NAME.)
CMUCL 20f released
Because of the release, there will not be a 2014-10 snapshot.
The official web presence is at www.cmucl.org with mirrors at www.cons.org/cmucl and at common-lisp.net/project/cmucl/mirror. There may be some duplication between the wiki and the web pages; the wiki tends to be more up-to-date.
