LISP
Definition
LISP is a multi-paradigm family of programming languages. It was and is popular in artificial intelligence research, but also for teaching programming fundamentals in elite schools.
“Lisp is a family of computer programming languages with a long history and a distinctive, fully parenthesized syntax. Originally specified in 1958, Lisp is the second-oldest high-level programming language in widespread use today; only Fortran is older. Like Fortran, Lisp has changed a great deal since its early days, and a number of dialects have existed over its history. Today, the most widely known general-purpose Lisp dialects are Common Lisp and Scheme. (Wikipedia, retrieved 17:56, 10 April 2008 (UTC))”
“Common Lisp is well suited to large programming projects and explorative programming. The language has a dynamic semantics which distinguishes it from languages such as C and Ada. It features automatic memory management, an interactive incremental development environment, a module system, a large number of powerful data structures, a large standard library of useful functions, a sophisticated object system supporting multiple inheritance and generic functions, an exception system, user-defined types and a macro system which allows programmers to extend the language.[ http://www.cons.org/cmucl/ CMUCL], retrieved 17:56, 10 April 2008 (UTC)).”
On a personal note: LISP is the only programming language, the main contributor to this Wiki ever liked. Same is true for a special purpose PC I worked with in the late eighties, a Symbolics 3620. It was the future in many ways. I started this page because I do teach some more recent stuff like JavaScript or PHP basics to non-programmers and sometimes (like today) I just wonder why those languages are so ugly and so unreliable compared to what we had 20 years ago and after some googling I found out that LISP and even AI is well alive and maybe even coming back a bit. Maybe I should trash PHP teaching at TECFA and go for Scheme instead :)
Today, there are still several popular flavors of LISP, e.g.
- CommonLISP (the dominant LISP before the 90' "AI winter"
- Scheme
- EmacsLISP (to program the Emacs editor)
Furthermore, there exist libraries for various programming languages and that implement subsets of LISP or Scheme or implement at least some features.
In education
- A large part (or even the majority) of Intelligent tutoring systems have been programmed in LISP or on top of expert system engines programmed in LISP.
- Lisp-based web servers can be used to implement adaptive hypertext systems.
