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 ...
[3] [4] The main point of divergence at the time was a clean bootstrapping procedure: CMUCL requires an already compiled executable binary of itself to compile the CMUCL source code, whereas SBCL supported bootstrapping from theoretically any ANSI-compliant Common Lisp implementation. SBCL became a SourceForge project in September 2000. [3]
Clozure CL (CCL) Originally a free and open-source fork of Macintosh Common Lisp. As that history implies, CCL was written for the Macintosh, but Clozure CL now runs on macOS, FreeBSD, Linux, Solaris and Windows. 32 and 64 bit x86 ports are supported on each platform. Additionally there are Power PC ports for Mac OS and Linux.
Lisp evaluates expressions which are entered by the user. Symbols and lists evaluate to some other (usually, simpler) expression – for instance, a symbol evaluates to the value of the variable it names; (+ 2 3) evaluates to 5. However, most other forms evaluate to themselves: if entering 5 into Lisp, it returns 5.
CL programmers use the language's package facility to declare which functions or data structures are intended for export. Apart from normal ("primary") methods, there also are :before, :after, and :around "auxiliary" methods. The former two are invoked prior to, or after the primary method, in a particular order based on the class hierarchy.
[5] BBN LISP: 1966: BBN: Based on L. Peter Deutsch's Lisp implementation for PDP-1, which was developed from 1960 to 1964; in time language was expanded until it became its own separate dialect in 1966; later renamed Interlisp [6] Chez Scheme: 1985: R. Kent Dybvig: Scheme dialect: Chialisp: 2019: Bram Cohen
Hemlock is a free Emacs text editor for most POSIX-compliant Unix systems. It follows the tradition of the Lisp Machine editor ZWEI and the ITS/TOPS-20 implementation of Emacs, but differs from XEmacs or GNU Emacs, the most popular Emacs variants, in that it is written in Common Lisp rather than Emacs Lisp and C—although it borrows features from the later editors.
Interlisp (also seen with a variety of capitalizations) is a programming environment built around a version of the programming language Lisp.Interlisp development began in 1966 at Bolt, Beranek and Newman (renamed BBN Technologies) in Cambridge, Massachusetts with Lisp implemented for the Digital Equipment Corporation (DEC) PDP-1 computer by Danny Bobrow and D. L. Murphy.
