XLISP is a family of Lisp programming language Lisp implementations written by David Betz . The first version was a Lisp with Object oriented programming object oriented extensions for computers with limited power. The second version XLISP 2.0 moved toward Common Lisp , but was by no means a complete implementation. After a long period of inactivity, the author released a new version based on XSCHEME , his Scheme implementation. The most current version follows the Scheme programming language Scheme R3RS standard. Derivatives AutoLISP , a programming and scripting language for AutoCAD , is based on a very old version of XLISP. XLISP PLUS is a derivative of XLISP 2.0 that continues to add Common Lisp features. Winterp is a derivative of XLISP PLUS. XLISP STAT is an implementation of Lisp Stat , an environment for dynamic graphics and statistics with objects. Nyquist programming language Nyquist is an extension of XLISP for sound synthesis. ANIMAL image processing ANIMAL AN IMage ALgebra is an image manipulation environment created by Carla Maria Modena and Roberto Brunelli. A 1989 entry to the IOCCC identifies itself as XLISP 4.0 .

ANIMAL first implementation 1988 revised 2004 is an interactive environment for Image processing that is oriented toward the rapid prototyping, testing, and modification of algorithms. To create ANIMAL AN IMage ALgebra , XLISP of David Betz was extended with some new types sockets, arrays, images, masks, and drawables. The theoretical framework and the implementation of the working environment is described in the paper http tev.fbk.eu people modena Papers BruMod AF 1989.pdf ANIMAL AN IMage ALgebra ref R. Brunelli and C. M. Modena, ANIMAL AN IMage ALgebra , High Frequency, 1989, LVIII 3 255 259 ref . In the theoretical framework of ANIMAL a digital image is a boundless matrix with its history . However, in the implementation it is bounded by a rectangular region in the discrete plane and the elements outside the region have a constant value. The size and position of the region in the plane focus is defined by the coordinates of the rectangle. In this way all the pixel s, including those on the border, have the same number of neighbors useful in local operators, such as digital filter s . Furthermore, pixelwise commutative operation s remain commutative on image level, independently on focus size and position of the rectangular regions . The history is a list which tracks the operations and parameters applied to the matrix. This mechanism is useful to document algorithms and generate new functions. ANIMAL has been ported to R programming language R , a freely available language and environment for statistical computing and graphics. http tev.fbk.eu TM AnImAl.tgz The new implementation is free and is used in a recent book ref R.

unreferenced date February 2012 Infobox programming language name Nyquist logo paradigm year designer Roger Dannenberg developer Roger Dannenberg latest release version latest release date typing implementations influenced by Lisp 28programming language 29 Lisp influenced Nyquist is a programming language for sound synthesis and analysis based on the Lisp programming language . It is an extension of the XLISP dialect of Lisp. With Nyquist, the programmer designs musical instruments by combining functions, and can call upon these instruments and generate a sound just by typing a simple expression. The programmer can combine simple expressions into complex ones to create a whole composition, and can also generate various other kinds of musical and non musical sounds. The Nyquist interpreter can read and write sound files, MIDI files, and Adagio computer music Adagio text based music score files. On many platforms, it can also produce direct audio output in real time. The Nyquist programming language can also be used to write plug in effects for the Audacity digital audio editor. One notable difference between Nyquist and more traditional MUSIC N languages is that Nyquist does not segregate synthesis functions see unit generator from scoring functions. For example Csound is actually two languages, one for creating orchestras the other for writing scores . With Nyquist these two domains are combined. Nyquist runs under Linux and other Unix environments, Mac OS , and Microsoft Windows . The Nyquist programming language and interpreter were written by Roger Dannenberg at Carnegie Mellon University , with support from Yamaha Corporation and IBM .

refimprove date February 2012 AutoLISP is a dialect of Lisp programming language built specifically for use with the full version of AutoCAD and its derivatives, which include AutoCAD Map 3D , AutoCAD Architecture and AutoCAD Mechanical . Neither the application programming interface nor the Interpreter computing interpreter to execute AutoLISP code are included in the AutoCAD LT product line. Features AutoLISP is a small, Scope programming dynamically scoped , dynamically typed Lisp programming language LISP dialect with garbage collection, immutable list structure and settable symbols, lacking in such regular LISP features as Macro computer science macro system , records definition facilities, arrays, functions with variable number of arguments or let bindings. Aside from the core language, most of the primitive functions are for geometry, accessing AutoCAD s internal DWG database, or manipulation of graphical entities in AutoCAD. The properties of these graphical entities are revealed to AutoLISP as association list s in which values are paired with AutoCAD group codes that indicate properties such as definitional points, radii, colors, layers, linetypes, etc. AutoCAD loads AutoLISP code from .LSP files. AutoLISP code can interact with the user through Autocad s graphical editor by use of primitive functions that allow user to pick points, choose objects on screen, input numbers and other data. AutoLisp also has a built in GUI mini language, the Dialog Control Language , for creating modal dialog boxes with automated layout, within AutoCAD. History AutoLISP was derived from a very early version of XLISP , which was created by David Betz . The language was introduced in AutoCAD Version 2.18 in January 1986, and continued to be enhanced in successive releases up to Release 13 in February 1995. After that, its development was neglected by Autodesk in favor of more fashionable development environments like Visual Basic for Applications VBA , .NET Framework .NET and O ... more details
