Lisp (programming Language)
Lisp (historically LISP) is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in 1960, Lisp 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 functions, recursion, the self-hosting compiler, and the rea ...

Multi-paradigm Programming Language
Programming paradigms are a way to classify programming languages based on their features. Languages can be classified into multiple paradigms. Some paradigms are concerned mainly with implications for the execution model of the language, such as allowing Side effect (computer science), side effects, or whether the sequence of operations is defined by the execution model. Other paradigms are concerned mainly with the way that code is organized, such as grouping a code into units along with the state that is modified by the code. Yet others are concerned mainly with the style of syntax and grammar. Common programming paradigms include: * imperative programming, imperative in which the programmer instructs the machine how to change its state, ** procedural programming, procedural which groups instructions into procedures, ** object-oriented programming, object-oriented which groups instructions with the part of the state they operate on, * declarative programming, declarative ...

Interlisp
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. In 1970, Alice K. Hartley implemented BBN LISP, which ran on PDP-10 machines running the operating system TENEX (renamed TOPS-20). In 1973, when Danny Bobrow, Warren Teitelman and Ronald Kaplan moved from BBN to the Xerox Palo Alto Research Center ( PARC), it was renamed Interlisp. Interlisp became a popular Lisp development tool for artificial intelligence (AI) researchers at Stanford University and elsewhere in the community of the Defense Advanced Research Projects Agency (DARPA). Interlisp was notable for integrating interactive development tools into an integrated development environment (IDE), such a ...

Cadence SKILL
SKILL is a Lisp dialect used as a scripting language and PCell (parameterized cells) description language used in many EDA software suites by Cadence Design Systems. It was originally put forth in an IEEE paper in 1990. History SKILL was originally based on a flavor of Lisp called Franz Lisp created at UC Berkeley by the students of Professor Richard J. Fateman. SKILL is not an acronym; it is a name. For trademark reasons Cadence prefers it be capitalized. Franz Lisp and all other flavors of LISP were eventually superseded by an ANSI standard for Common Lisp. Historically, SKILL was known as IL. SKILL was a library of IL functions. The name was originally an initialism for Silicon Compiler Interface Language (SCIL), pronounced "SKIL", which then morphed into "SKILL", a plain English word that was easier for everyone to remember. "IL" was just Interface Language. Although SKILL was used initially to describe the API rather than the language, the snappier name stuck. The name " ...

Scheme (programming Language)
Scheme is a dialect of the Lisp family of programming languages. Scheme was created during the 1970s at the MIT AI Lab and released by its developers, Guy L. Steele and Gerald Jay Sussman, via a series of memos now known as the Lambda Papers. It was the first dialect of Lisp to choose lexical scope and the first to require implementations to perform tail-call optimization, giving stronger support for functional programming and associated techniques such as recursive algorithms. It was also one of the first programming languages to support first-class continuations. It had a significant influence on the effort that led to the development of Common Lisp.Common LISP: The Language, 2nd Ed., Guy L. Steele Jr. Digital Press; 1981. . "Common Lisp is a new dialect of Lisp, a successor to MacLisp, influenced strongly by ZetaLisp and to some extent by Scheme and InterLisp." The Scheme language is standardized in the official IEEE standard1178-1990 (Reaff 2008) IEEE Standard for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RPL (programming Language)
RPL is a handheld calculator operating system and application programming language used on Hewlett-Packard's scientific graphing RPN (Reverse Polish Notation) calculators of the HP 28, 48, 49 and 50 series, but it is also usable on non-RPN calculators, such as the 38, 39 and 40 series. RPL is a structured programming language based on RPN, but equally capable of processing algebraic expressions and formulae, implemented as a threaded interpreter. RPL has many similarities to Forth, both languages being stack-based, as well as the list-based LISP. Contrary to previous HP RPN calculators, which had a fixed four-level stack, the stack used by RPL is only limited by available calculator RAM. RPL originated from HP's Corvallis, Oregon development facility in 1984 as a replacement for the previous practice of implementing the operating systems of calculators in assembly language. The last pocket calculator supporting RPL, the HP 50g, was discontinued in 2015. However, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Racket (programming Language)
Racket is a general-purpose, multi-paradigm programming language and a multi-platform distribution that includes the Racket language, compiler, large standard library, IDE, development tools, and a set of additional languages including Typed Racket (a sister language of Racket with a static type-checker), Swindle, FrTime, Lazy Racket, R5RS & R6RS Scheme, Scribble, Datalog, Racklog, Algol 60 and several teaching languages. The Racket language is a modern dialect of Lisp and a descendant of Scheme. It is designed as a platform for programming language design and implementation. In addition to the core Racket language, ''Racket'' is also used to refer to the family of programming languages and set of tools supporting development on and with Racket. Racket is also used for scripting, computer science education, and research. The Racket platform provides an implementation of the Racket language (including a runtime system, libraries, and compiler supporting several compilation mo ...

Portable Standard Lisp
Portable Standard Lisp (PSL) is a programming language, a dialect of the language Lisp. PSL was inspired by its predecessor, ''Standard Lisp'' and the Portable Lisp Compiler. It is tail-recursive, late binding (or dynamically bound), and was developed by researchers at the University of Utah in 1980, which released PSL 3.1; development was handed over to developers at Hewlett-Packard in 1982 who released PSL 3.3 and up. Portable Standard Lisp was available as a kit containing a screen editor, a compiler, and an interpreter for several hardware and operating system computing platforms, including Motorola 68000 series, DECSYSTEM-20s, Cray-1s, VAX, and many others. Today, PSL is mainly developed by and available from Konrad-Zuse-Zentrum für Informationstechnik Berlin (ZIB). Its main modern use is as the underlying language for implementations of Reduce. Like most older Lisps, in the first step, PSL compiles Lisp code to LAP code, which is another cross-platform language. How ...

Picolisp
PicoLisp is a programming language, a dialect of the language Lisp. It runs on operating systems including Linux and others that are ''Portable Operating System Interface'' (POSIX) compliant. Its most prominent features are simplicity and minimalism. It is built on one internal data type: a cell. On the language level, a programmer can use three different data types (numbers, symbols, and lists) being represented by cells and differentiated by bits at the end of the cell. It is free and open-source software released under an MIT License (X11). Features Functions can accept arbitrary types and numbers of arguments. Macros are needed only in rare cases and are implemented using the quote function. PicoLisp does not include Lisp's lambda function. This is because the quote function is changed to return all its arguments unevaluated, not only the car of the first. A special feature is the intrinsic ''create, read, update, and delete'' (CRUD) functioning. Persistent symbols are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NIL (programming Language)
New Implementation of LISP (NIL) is a programming language, a dialect of the language Lisp, developed at the Massachusetts Institute of Technology (MIT) during the 1970s, and intended to be the successor to the language Maclisp. It is a 32-bit implementation, and was in part a response to Digital Equipment Corporation's (DEC) VAX computer. The project was headed by Jon L White, with a stated goal of maintaining compatibility with MacLisp while fixing many of its problems. History The Lisp language was invented in 1958 by John McCarthy while he was at Massachusetts Institute of Technology (MIT). From its inception, Lisp was closely connected with the artificial intelligence (AI) research community, especially on PDP-10 systems. The 36-bit word size of the PDP-6 and PDP-10 was influenced by the usefulness of having two Lisp 18-bit pointers in one word: "The PDP-6 project started in early 1963, as a 24-bit machine. It grew to 36 bits for LISP, a design goal." Lisp was used a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NewLISP
newLISP is a scripting language which is a dialect of the Lisp family of programming languages. It was designed and developed by Lutz Mueller. newLISP is free and open-source software released under the GNU General Public License, version 3 or later. History newLISP design is influenced by the two main Lisp dialects, Common Lisp and Scheme, and by other languages like Pascal and C. newLISP originated in 1991 and was originally developed on a Sun-4 workstation. It later moved to Windows 3.0, where version 1.3 was released on CompuServe around 1993, then became available as a Windows graphical user interface (GUI) graphics-capable application and a DOS console application (both 16-bit). In 1995, with the release of Windows 95, newLISP moved to 32-bit. In April 1999, newLISP was ported to Linux; some of its core algorithms were rewritten, and all Windows-specific code removed. newLISP was released as an open-source software project licensed under the GPL, and developmen ...

MDL (programming Language)
MDL (Model Development Language, or colloquially also referred to as More Datatypes than Lisp or MIT Design Language) is a programming language, a descendant of the language Lisp. Its initial purpose was to provide high level language support for the Dynamic Modeling Group at Massachusetts Institute of Technology's (MIT) Project MAC. It was developed in 1971 on a PDP-10 running ITS and later ran on TENEX, TOPS-20, BSD, and AEGIS. The initial development team consisted of Gerald Sussman and Carl Hewitt of the Artificial Intelligence Lab, and Chris Reeve, Bruce Daniels, and David Cressey of the Dynamic Modeling Group. Later, Stu Galley, also of the Dynamic Modeling Group, wrote the MDL documentation. MDL was initially called ''Muddle''. This style of self-deprecating humor was not widely understood or appreciated outside of Project MAC. So the name was sanitized to MDL. MDL provides several enhancements to classic Lisp. It supports several built-in data types, includi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
