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 ...
Steel Bank Common Lisp (SBCL) is a free and open-source Common Lisp implementation that features a high-performance native compiler, Unicode support and threading. It is open source software, with a permissive license.
Common Lisp is sometimes termed a Lisp-2 and Scheme a Lisp-1, referring to CL's use of separate namespaces for functions and variables. (In fact, CL has many namespaces, such as those for go tags, block names, and loop keywords). There is a long-standing controversy between CL and Scheme advocates over the tradeoffs involved in multiple namespaces.
Allegro CL can be used to deliver applications. Allegro CL is available as freeware, a Free Express Edition (with some limits like a constrained heap space) for non-commercial use. [5] Customers can get access to much of the source code of Allegro CL. Allegro CL includes an implementation of Prolog [6] and an object caching database called ...
Scheme is a statically scoped and properly tail-recursive dialect of the Lisp programming language invented by Guy L. Steele, Jr. and Gerald Jay Sussman. It was designed to have exceptionally clear and simple semantics and few different ways to form expressions. Designed about a decade earlier than Common Lisp, Scheme is a more minimalist design.
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.
The earliest implementation predates Common Lisp and was part of Spice Lisp, around 1980.In 1985 Rob MacLachlan started re-writing the compiler to what would become the Python compiler and CMUCL was ported to Unix workstations such as the IBM PC RT, MIPS and SPARC.
CLISP is extremely portable, running on almost all Unix-based operating systems as well as on Microsoft Windows.Although interpreting bytecode is usually slower than running compiled native binaries, this is not always a major issue (especially in applications like Web development where I/O is the bottleneck).
