Clozure CL is a Common Lisp implementation the PowerPC and AMD64. There is a pre-release x86 version. It is easily the most popular choice on Mac OS X, but it runs equally well on GNU/Linux and FreeBSD/amd64 systems; there is also a beta for Windows. On Mac OS X, CCL features a Cocoa interface. I want to manually set up my own Emacs CL environment on Mac OS X 7 without the SLIME package i.e. It will only use Clozure CL. To put it other way, I want to use the Emacs CL just like I use the 'Inferior Emacs Lisp Mode' (M-x ielm) but instead of the plain old Emacs Lisp, it'll use the Clozure CL.

Clozure CL (CCL) is a Common Lisp implementation. It implements the full ANSI Common Lisp standard with several extensions (CLOS MOP, threads, CLOS conditions, CLOS streams, ..). It contains a command line development environment, an experimental integrated development environment (IDE) for Mac OS X using the Hemlock editor, and can also be used with SLIME (a Common Lisp development environment for GNU Emacs). Clozure CL is open source and the project is hosted by Clozure Associates.

Supported platforms[edit]

Clozure CL supports the Mac OS X, Linux, FreeBSD, Solaris and Microsoft Windows platforms. There are 32 and 64 bit x86 variants for each. Additionally, there are PowerPC ports for Mac OS X and Linux, and a 32-bit ARM port for Linux.

Applications[edit]

Clozure CL was used by ITA Software for the business logic of a new Airline Reservation System.^[3]

Clozure CL is also commonly used as an underlying Common Lisp implementation for the ACL2 theorem prover.^[4]

History[edit]

Formerly known as OpenMCL, Clozure CL is an evolution of Macintosh Common Lisp.

Technology[edit]

CCL contains a precise, generational, compacting garbage collector. CCL's compiler produces native instructions for Lisp expressions and files. By default every expression entered at the REPL is compiled to native code.

Lisp threads are implemented as preemptively-scheduled, native operating-system threads.

CCL implements built-in facilities to easily interface with C and Objective-C libraries (Cocoa bridge) and these are used to implement the IDE amongst other things.

The IDE (based upon the Hemlock editor) is currently labelled as experimental. An effort^{[better source needed][5]} is underway to improve this.

• Excellent Common Lisp environment

  
  
  If one cares to develop in Common Lisp, or just plainly creating great apps, give Clozure Common Lisp (CCL) a chance. You do not need Emacs with this, just jump right in on one of the greatest dev environment available.

• Amazing implementation of an amazing language

  
  
  It's running again under Mojave. Thanks to the clozure for submitting this update.

• AWESOME

  
  
  Really great way to get started with CL on OSX. I just started today to try CL for some web programming (yes lisp is great for web stuff too) and Clozure is simply the best to get up and running soon. It comes with a complete IDE so no need to use EMACS which, by itself, is a great plus.

• Excellent implementation of Common Lisp with a long history..

  
  
  Clozure CL has its roots in MCL, the excellent Macintosh Common Lisp environment developed by Coral Lisp, and at one time actually owned by Apple. CCL is a new, high performance implementation for the Intel architecture. It also runs on Windows, but is a true OS X implementation.Without question, it is the best Lisp on OS X.
