'''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 (text editor)|Hemlock]] editor, and can also be used with [[SLIME]] (a Common Lisp development environment for [[GNU Emacs]]). Clozure CL is [[Open-source software|open source]] and the project is hosted by Clozure Associates.
Clozure CL runs on [[PowerPC]] [[Macintosh]] computer systems under [[Mac OS X]] and [[Linux]], and [[x86-64]] systems under Mac OS X, Linux, and [[FreeBSD]]. Ports to [[IA-32]] and 64-bit Windows are in development.

Formerly known as OpenMCL, Clozure CL (sometimes abbreviated as CCL) is an evolution of [[MCL]]. Clozure CL is [[open source]] and is effectively "owned" by Clozure Associates.

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.
