Clozure CL is an implementation of Common Lisp, an object-oriented dynamic programming language. It includes a fast compiler, support for native threads, a sophisticated garbage collector, and a convenient interface for calling C and Objective-C code.


Release Notes:

Compiler updated to version 1.11. Includes bug fixes and performance improvements.

The 1.11.1 update does not pre-load ASDF in the image file. ASDF is still bundled, however, and you load it as normal with (require 'asdf).

Great Common Lisp implementation - We have used CCL for many years. This is not just a great Common Lisp implementation but also a highly agile development platform to create higher level programming languages with.

Review by BillInWebster

Outstanding CL, true Mac UI, no extra junk - I teach AI and Lisp at the university level and was looking for a true Common Lisp implementation for the Mac that will let you develop serious projects, but not have all the Rube Goldberg extras of overly-engineered (and either expensive or limited) alternatives. CCL is the best — and I’ve used Lisp, many development environments, for a lot longer than my students have been alive. Nice, clean interface, easy for a beginnner to learn and manage, but with the full power of Lisp under it. Only complaint is that there’s no way I can see to pay for this software. I woud do that happily, and ask my students to do so as well.
