Common Lisp
Common Lisp (CL) is a dialect of the Lisp programming language, published in American National Standards Institute (ANSI) standard document ''ANSI INCITS 226-1994 (S2018)'' (formerly ''X3.226-1994 (R1999)''). The Common Lisp HyperSpec, a hyperlinked HTML version, has been derived from the ANSI Common Lisp standard. The Common Lisp language was developed as a standardized and improved successor of Maclisp. By the early 1980s several groups were already at work on diverse successors to MacLisp: Lisp Machine Lisp (aka ZetaLisp), Spice Lisp, NIL and S-1 Lisp. Common Lisp sought to unify, standardise, and extend the features of these MacLisp dialects. Common Lisp is not an implementation, but rather a language specification. Several implementations of the Common Lisp standard are available, including free and open-source software and proprietary products. Common Lisp is a general-purpose, multi-paradigm programming language. It supports a combination of procedural, functional ...

Lisp (programming Language)
Lisp (historically LISP, an abbreviation of "list processing") is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in the late 1950s, it is the second-oldest high-level programming language still in common use, after Fortran. Lisp has changed since its early days, and many dialects have existed over its history. Today, the best-known general-purpose Lisp dialects are Common Lisp, Scheme, Racket, and Clojure. Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though not originally derived from) the notation of Alonzo Church's lambda calculus. It quickly became a favored programming language for artificial intelligence (AI) research. As one of the earliest programming languages, Lisp pioneered many ideas in computer science, including tree data structures, automatic storage management, dynamic typing, conditionals, higher-order function ...

Dynamic Typing
In computer programming, a type system is a logical system comprising a set of rules that assigns a property called a ''type'' (for example, integer, floating point, string) to every '' term'' (a word, phrase, or other set of symbols). Usually the terms are various language constructs of a computer program, such as variables, expressions, functions, or modules. A type system dictates the operations that can be performed on a term. For variables, the type system determines the allowed values of that term. Type systems formalize and enforce the otherwise implicit categories the programmer uses for algebraic data types, data structures, or other data types, such as "string", "array of float", "function returning boolean". Type systems are often specified as part of programming languages and built into interpreters and compilers, although the type system of a language can be extended by optional tools that perform added checks using the language's original type syntax ...

Genera (operating System)
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

SBCL
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. In addition to the compiler and runtime system for ANSI Common Lisp, it provides an interactive environment including a debugger, a statistical profiler, a code coverage tool, and many other extensions. The name "Steel Bank Common Lisp" is a reference to Carnegie Mellon University Common Lisp from which SBCL forked: Andrew Carnegie made his fortune in the steel industry and Andrew Mellon was a successful banker. History SBCL descends from CMUCL (created at Carnegie Mellon University), which is itself descended from Spice Lisp, including early implementations for the Mach operating system on the IBM RT PC, and the Three Rivers Computing Corporation PERQ computer, in the 1980s. William Newman originally announced SBCL as a variant of CMUCL in December 1999. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LispWorks
LispWorks is computer software, a proprietary implementation and integrated development environment (IDE) for the programming language Common Lisp. LispWorks was developed by the UK software company Harlequin Ltd., and first published in 1989. Harlequin ultimately spun off its Lisp division as Xanalys Ltd., which took over management and rights to LispWorks. In January 2005, the Xanalys Lisp team formed LispWorks Ltd. to market, develop, and support the software. LispWorks's features include: * A native-code compiler and an interpreter for an extended ANSI Common Lisp * An implementation of the Common Lisp Object System with support for the metaobject protocol * Support for 32-bit and 64-bit versions * Native threads and symmetric multiprocessing * Unicode support: it can read and write files, and supports strings, so encoded * Foreign language interface (FFI) to interface with routines written in C * A Java interface * The ''common application programming interface'' (CAPI ...

GNU Common Lisp
GNU Common Lisp (GCL) is the GNU Project's ANSI Common Lisp compiler, an evolutionary development of Kyoto Common Lisp. It produces native object code by first generating C code and then calling a C compiler. GCL is the implementation of choice for several large projects including the mathematical tools Maxima, AXIOM, HOL88, and ACL2. GCL runs under eleven different architectures on Linux, and under FreeBSD, Solaris, Mac OS X, and Microsoft Windows. Last stable release of GCL is of April 11, 2025.

Embeddable Common Lisp
Embeddable Common Lisp (ECL) is a small implementation of the ANSI Common Lisp programming language that can be used stand-alone or embedded in extant applications written in C. It creates OS-native executables and libraries (i.e. Executable and Linkable Format (ELF) files on unix) from Common Lisp code, and runs on most platforms that support a C compiler. The ECL runtime is a dynamically loadable library for use by applications. It is distributed as free software under a GNU Lesser Public License (LGPL) 2.1+. It includes a runtime system, and two compilers, a bytecode interpreter allowing applications to be deployed where no C compiler is expected, and an intermediate language type, which compiles Common Lisp to C for a more efficient runtime. The latter also features a native foreign function interface (FFI), that supports inline C as part of Common Lisp. Inline C FFI combined with Common Lisp macros, custom Lisp setf expansions and compiler-macros, result in a custom compile- ...

CMUCL
CMUCL is a free Common Lisp implementation, originally developed at Carnegie Mellon University. CMUCL runs on most Unix-like platforms, including Linux and BSD; there is an experimental Windows port as well. Steel Bank Common Lisp is derived from CMUCL. The Scieneer Common Lisp was a commercial derivative from CMUCL. History 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. Early CMUCL releases did not support Intel's x86 architecture due to a lack of registers. CMUCL strictly separated type-tagged and immediate data types and the garbage collector would rely on knowing that one half of the CPU registers could only hold tagged types and the other half only untagged types. This did not leave enough registers for a Python backend. After CMU canceled the project (in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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 Clozure CL was used by ITA Software for the business logic of a new Airline Reservation System Airline reservation systems (ARS) are systems that allow an airline to sell their inventory (seats).

CLISP
CLISP is an implementation of the programming language Common Lisp originally developed by Bruno Haible and Michael Stoll for the Atari ST. Today it supports the Unix and Microsoft Windows operating systems. CLISP includes an interpreter, a bytecode compiler, debugger, socket interface, high-level foreign language interface, strong internationalization support, and two object systems: Common Lisp Object System (CLOS) and metaobject protocol (MOP). It is written in C and Common Lisp. It is now part of the GNU Project and is free software, available under the terms of the GNU General Public License (GPL). History Haible did not originally intend to distribute CLISP under the GPL, but in a well-publicised email exchange with Richard Stallman, he eventually agreed to do so. The issue at stake was whether CLISP was a derivative work of the GNU readline library. Ports CLISP is extremely portable, running on almost all Unix-based operating systems as well as on Microsoft Windows. Alth ...
