XLISP is a family of multi-platform LISP implementations. They comprise of a Scheme compatible interpreter (bytecode compiler for versions 3 and higher) called XLISP originally written by David Betz. He added few object oriented features taken from Smalltalk to the basic Scheme language. The core runtime is written in C while the rest is implemented in XLISP itself. The program was released into the public domain until about version 2.1 where the license was changed. XLISP 2.1 is also the last version of the original XLISP package to be available in an OS/2 port.
The program was first released in 1983 as eXperimental LISP and was at the time a generic small LISP subset that was not Scheme compatible. When the first Scheme compatible version came out Mr. Betz changed the name of the package to XScheme but changed it back to XLISP after a couple of years. Various versions of the package are used in open source projects externally or internally as scripting engines. It is also the basis for the LISP that is used as an internal scripting engine by AutoCAD (AutoLISP) and some compatible packages like IntelliCAD.
Forks
- XLISP-PLUS
- WINTERP is a derivative of XLISP-PLUS 2.1 that adds widget support for UNIX like operating systems that have the Motif widget library installed.
- XLISP-STAT
- Vienna LISP, also known as VLISP is an XLISP fork that is Common LISP compatible and adds a bytecode compiler, note that Vienna LISP is preferred usage over VLISP since there are at the least five other projects that use the VLISP moniker.
- Nyquist is a music programming language based on XLISP.
- S-Lisp bolts s 3D graphics library onto XLISP. An Image Algebra or ANIMAL was an experimental version that handled image processing.
