## Definition[edit | edit source]

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. 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[edit | edit source]

* 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.

## Software[edit | edit source]

### Common LISP implementations[edit | edit source]

There exist a number of good Common Lisp implementations, including a few free ones (updated 17/2020).

Free implementations

* Steel Bank Common Lisp "is a high performance Common Lisp compiler. It is open source / free 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.". A branch from CMUCL, it runs on a number of POSIX platforms, and experimentally on Windows.

* CLISP. "CLISP includes an interpreter, a compiler, a debugger, CLOS, MOP, a foreign language interface, i18n, POSIX and Perl regular expressions, a socket interface, fast bignums, arbitrary precision floats, and more.". Runs under Linux, MacOS X and Windows (via cywin)

* CMUCL. A free implementation of the Common Lisp programming language which runs on most major Unix platforms.

* GCL The GNU implementation of Common Lisp.

* Clozure CL "(often called CCL for short) is a free Common Lisp implementation with a long history. Some distinguishing features of the implementation include fast compilation speed, native threads, a precise, generational, compacting garbage collector, and a convenient foreign-function interface."

Commercial

* Allegro Common Lisp (Franz Inc.)
* LispWorks. A free (heap and time limited) version is available for personal use.

### Webservers in LISP or Scheme[edit | edit source]

* CL-HTTP was developped at MIT under the lead of J. Mallery. The system seems to be no longer maintained.

* araneida. Araneida is a fairly small free extensible Web server for SBCL and many other Common Lisp implementations .

* Hunchentoot The Common Lisp web server formerly known as TBNL

* Mod_lisp to run a lisp with Apache.

* AllegroServe. a Web HTTP/Application Server. Free (LLGPL), made by John Foderaro (Franz Inc.)

### Repositories[edit | edit source]

* CMU Artificial Intelligence Repository

* See also [CLIKI

### Various links[edit | edit source]

See CLIKI. It "contains resources for learning about and using the programming language Common Lisp, and information about DFSG-compliant free software implemented in Common Lisp."

For example:

* web
* AI

## Links[edit | edit source]

* Cliki The common lisp wiki. Probably the best overal resource currently. Sorted by resources type or application domain.

* Lisp-lang.org. A tutorial.

* Lisperati Funny and serious.

### Collections of links[edit | edit source]

* LISP Links (Paul Graham).

### Opinions[edit | edit source]
