Lisp historically, LISP is a family of computerprogramming languages with a long history and a distinctive, fully parenthesizedprefix notation. Originally specified in 1. Lisp is the second oldest high level programming language in widespread use today. Only Fortran is older, by one year. 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 and Scheme. Lisp was originally created as a practical mathematical notation for computer programs, influenced by the notation of Alonzo Churchs lambda calculus. It quickly became the 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 hostingcompiler,6 and the readevalprint loop. The name LISP derives from LISt Processor. Linked lists are one of Lisps major data structures, and Lisp source code is made of lists. Thus, Lisp programs can manipulate source code as a data structure, giving rise to the macro systems that allow programmers to create new syntax or new domain specific languages embedded in Lisp. The interchangeability of code and data gives Lisp its instantly recognizable syntax. Lisp historically, LISP is a family of computer programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally. All program code is written as s expressions, or parenthesized lists. A function call or syntactic form is written as a list with the function or operators name first, and the arguments following for instance, a function f that takes three arguments would be called as farg. HistoryeditLisp was invented by John Mc. Carthy in 1. 95. 8 while he was at the Massachusetts Institute of Technology MIT. Mc. Carthy published its design in a paper in Communications of the ACM in 1. Recursive Functions of Symbolic Expressions and Their Computation by Machine, Part I. He showed that with a few simple operators and a notation for functions, one can build a Turing complete language for algorithms. Information Processing Language was the first AI language, from 1. Lisp. Mc. Carthys original notation used bracketed M expressions that would be translated into S expressions. As an example, the M expression carconsA,B is equivalent to the S expression carcons. AB. Once Lisp was implemented, programmers rapidly chose to use S expressions, and M expressions were abandoned. M expressions surfaced again with short lived attempts of MLISP1.

Nov/scraping.jpg' alt='New Boston Python Programming' title='New Boston Python Programming' />Lisp was first implemented by Steve Russell on an IBM 7. Russell had read Mc. Carthys paper and realized to Mc. Carthys surprise that the Lisp eval function could be implemented in machine code. The result was a working Lisp interpreter which could be used to run Lisp programs, or more properly, evaluate Lisp expressions. Two assembly language macros for the IBM 7. Contents of the Address part of Register number and cdr Contents of the Decrement part of Register number,1. See. CAR and CDR for the etymology of the terms. Movie Room Lighting Ideas here. Lisp dialects still use car and cdr and for the operations that return the first item in a list and the rest of the list respectively. The first complete Lisp compiler, written in Lisp, was implemented in 1. Tim Hart and Mike Levin at MIT. This compiler introduced the Lisp model of incremental compilation, in which compiled and interpreted functions can intermix freely. The language used in Hart and Levins memo is much closer to modern Lisp style than Mc. Carthys earlier code. Lisp was a difficult system to implement with the compiler techniques and stock hardware of the 1. Garbage collection routines, developed by then MIT graduate student Daniel Edwards, made it practical to run Lisp on general purpose computing systems, but efficiency was still a problem. This led to the creation of Lisp machines dedicated hardware for running Lisp environments and programs. During the 1. 98. Lisp dialects mostly successors to Maclisp like Zeta. Lisp and NIL New Implementation of Lisp into a single language. The new language, Common Lisp, was somewhat compatible with the dialects it replaced the book Common Lisp the Language notes the compatibility of various constructs. In 1. 99. 4, ANSI published the Common Lisp standard, ANSI X3. Information Technology Programming Language Common Lisp. TimelineeditConnection to artificial intelligenceeditSince inception, Lisp was closely connected with the artificial intelligence research community, especially on PDP 1. Lisp was used as the implementation of the programming language Micro Planner which was used in the famous AI system SHRDLU. In the 1. 97. 0s, as AI research spawned commercial offshoots, the performance of existing Lisp systems became a growing issue. Genealogy and variantseditOver its sixty year history, Lisp has spawned many variations on the core theme of an S expression language. Moreover, each given dialect may have several implementationsfor instance, there are more than a dozen implementations of Common Lisp. Differences between dialects may be quite visiblefor instance, Common Lisp uses the keyword defun to name a function, but Scheme uses define. Within a dialect that is standardized, however, conforming implementations support the same core language, but with different extensions and libraries. Historically significant dialectseditLISP 11. First implementation. LISP 1. 51. 7 First widely distributed version, developed by Mc. Carthy and others at MIT. So named because it contained several improvements on the original LISP 1 interpreter, but was not a major restructuring as the planned LISP 2 would be. Stanford LISP 1. 61. This was a successor to LISP 1. Stanford AI Lab, and widely distributed to PDP 1. TOPS 1. 0 operating system. It was rendered obsolete by Maclisp and Inter. Lisp. MACLISP1. 9 developed for MITs Project MAC no relation to Apples Macintosh, nor to Mc. Carthy, direct descendant of LISP 1. It ran on the PDP 1. Multics systems. MACLISP would later come to be called Maclisp, and is often referred to as Mac. Lisp. Inter. Lisp2. BBN Technologies for PDP 1. Tenex operating system, later adopted as a West coast Lisp for the Xerox Lisp machines as Inter. Lisp D. A small version called Inter. LISP 6. 5 was published for the 6. Atari 8 bit family computer line. For quite some time, Maclisp and Inter. Lisp were strong competitors. Franz Lisp originally a University of California, Berkeley project later developed by Franz Inc. The name is a humorous deformation of the name Franz Liszt, and does not refer to Allegro Common Lisp, the dialect of Common Lisp sold by Franz Inc., in more recent years. XLISP, which Auto. LISP was based on. Standard Lisp and Portable Standard Lisp were widely used and ported, especially with the Computer Algebra System REDUCE. Zeta.
