Stylish Lisp programming techniques As the size of software systems being created and more importantly maintained increases, it becomes more important than ever to write clean, robust, modular programs. Hoare's ``Emperor's New Clothes'' is a spectre that haunts anyone engaged in the task of creating complex software systems today. And in a future that promises automatic generation and verification of programs, programming constructs and techniques that have simple, rigorous semantics will be of primary importance to help these intelligent tools function. In light of this, I've put together a short list of lisp programming techniques that increase the clarity, robustness, and elegance of your code. Some have been floating around for years, but I don't think they've ever been collected in one place. So have fun... Technique n-2: Even though dynamically scoped lisps lack the ability to close a function over some piece of local state, we can get the same effect with clever manipulation of quoted constants inside a function. Consider the following function, ELEMENT-GENERATOR . On every call, it side effects a quoted list which is part of its definition. Thus, each time we call it, it returns the next element in its state list.

The Common Lisp Programming Language "The programming language of choice for those who set out to solve the world's very hardest problems." Think of Lisp as an alternative to or refuge from "commodity" languages like Java, C. and C++, especially for your most complex and difficult projects. The Lisp language family was originally designed four decades ago to aid the then-nascent Artificial Intelligence industry, and has proven itself over the interim to be a powerful ally in tackling the world's most difficult kinds of problems: problems that involve planning, problem solving, and learning problems whose specifications are ill-defined or change dynamically problems that involve qualitative reasoning problems involving heterogeneous data or considerable amounts of potentially erroneous data that must be sifted and repaired problems that require very fast time to market problems that must manage complex control flow, including sophisticated error handling Common Lisp is an ideal technology for addressing the problems of the modern web. Common Lisp is ANSI standard language X3.226-1994, renewed in 1999 and available from ANSI in PDF format as

The contest will be held from October 2 to November 15, 2000. First prize is a cash award of $250. Second prize gets $100, and third gets $50. Who is eligible? The contest is open to students at The Ohio State University. Undergraduate, graduate, full-time, part-time, whatever. As long as you're a student, you're eligible. Grad students are eligible, too? That's not fair! Stop whining. What are the rules? You need to produce a program that does something, anything. It also must contain functions needed to descramble CSS encrypted DVD content. We'll be using css_descramble.c by Derek Fawcus and M Roberts as our reference. Whether the CSS decryption is the primary purpose of the program is up to you, but we think it would be an awfully cool side-effect of a program that's really intended to do something else... The program maybe written in any language, but it must run under the CMU CL environment for Common Lisp. That is, if you write it in a language that you created yourself, you must make an interpreter for it in Common Lisp.

About Us Corman Lisp is a Common Lisp development environment for Microsoft Windows operating systems running on Intel platforms. Corman Lisp consists of a Common Lisp native code compiler for Intel processors, 80x86 assembler and disassembler, incremental linker and multi-window text editor. It requires a system running a Microsoft Windows operating system (such as Windows XP, Windows 2000, Windows ME or Windows NT). It is fully integrated with the Win32 API, and all the Windows API functions are readily available from Lisp. Corman Lisp incorporates state-of-the-art compiler technology to bring you a Common Lisp system unmatched on Windows platforms. Among the highlights of Corman Lisp: Fast multi-generational garbage collector . A state-of-the-art garbage collector supports extremely fast collection of short-lived objects, avoiding pauses for collection (which normally takes only a few milliseconds). The collector also supports compaction (automatic defragmentation of the heap), weak pointers, finalization functions and per-thread allocators. No interpreter.

Tutorials Nyquist Nyquist Introduction to Nyquist and Lisp Programming Programming in Nyquist Creating Nyquist Plug-ins Beginning with version 1.1.1, Audacity allows you to use the Nyquist programming language to write your own plug-in effects for Audacity. Unlike VST and LADSPA plug-ins, Nyquist plug-ins can be written using an ordinary text editor and don't need to be compiled. Nyquist was written by Roger B. Dannenberg and was intended to be used as a complete programming language for audio synthesis and analysis, with support for MIDI, audio recording and playback, file I/O, object-oriented programming, profiling, debugging, and more. Audacity uses only a subset of Nyquist's functionality, allowing you to take simple Nyquist functions and use them to process audio data. Audacity doesn't include any support for debugging Nyquist code, so if you are trying to write a complicated plug-in, you may find it easier to get the full version of Nyquist and develop there, then turn it into an Audacity plug-in. Nyquist is available from the Carnegie Mellon University Computer Music Project: CMU Computer Music Project Software - download the full Nyquist here Complete Nyquist Reference Manual at CMU Note that you don't need to download Nyquist in order to write simple plug-ins to use with Audacity.

Lisp Section Home Purchase Download Support ... Site Map Web digitool.com Common Lisp Benefits Common Lisp is available for almost all computers and operating systems. The days of Lisp interpreters have long-since passed; commercially-available Common Lisp systems have without exception included compilers for well over a decade. Thanks to dramatic advances in compiler technology and garbage collection (which makes possible automatic storage deallocation and absolutely eliminates memory leaks), the overall execution speed of Common Lisp programs is comparable to equivalent programs compiled by lower-order languages. Common Lisp is a very small language with a very large library. The library is best suited for complex algorithmic programs, such as those which make extensive use of dynamic data structures to solve problems in knowledge representation, scheduling, network management, and financial modeling. In fact, Common Lisp users have discovered that their programs can actually outperform sufficiently complex programs written in C++, because it is very difficult for a programmer to create efficient abstractions from scratch; Common Lisp users have the advantage of a large, well-defined library which is efficient thanks to constant feedback from many users. Common Lisp programs are among the easiest to port across vendors and platforms. Having a large standardized runtime library ensures that it performs the same way from vendor to vendor. Common Lisp provides more extensive abstractions "out of the box" than do other languages. Even better, its abstractions are designed to be free from dependencies of hardware representation. Common Lisp programs simply do not break because of word-size and byte-order issues when moved to a different platform.

Chapter 1 - Why Bother? Or: Objections Answered Everyone knows Lisp, right? Many of us took a course that introduced us to Lisp along with three or four or more other languages. This is how I was introduced to Lisp around 1975, and I thought it was a pretty useless language. It didn't do anything in the usual way, it was slow, and those parentheses were enough to drive anyone crazy! If your own Lisp experience predates 1985 or so, you probably share this view. But in 1984, the year Big Brother never really became a reality (did it?), the year that the first bleeding-edge (but pathetic by today's standards) Macintosh started volume shipments, the Lisp world started changing. Unfortunately, most programmers never noticed; Lisp's fortune was tied to AI, which was undergoing a precipitous decline The AI Winter just as Lisp was coming of age. Some say this was bad luck for Lisp. I look at the resurgence of interest in other dynamic languages and the problems wrestled with by practicioners and vendors alike, and wonder whether Lisp wasn't too far ahead of its time. I changed my opinion of Lisp over the years, to the point where it's not only my favorite progamming language, but also a way of structuring much of my thinking about programming. I hope that this book will convey my enthusiasm, and perhaps change your opinion of Lisp.

60. W. Richard Stark -- LISP So, lisp programming is entertaining from a mathematical or computationtheoretic point of view. LISP is usually associated with artificial intelligence. http://www.math.usf.edu/~stark/lisp.html

LISP ...) LISP is a computer language that is unique in that it is based on an algebraic structure, the lambda calculus, from pure mathematics. In its purest form, [1] there is no distinction between data and programming code, [2] LISP exists within itself in the form of the eval function, [3] the use of typing on data is optional and necessary only for very large programs, [4] it is not intended to be procedural, the function definitions of a LISP program could be shuffled before being entered into the machine and they would execute just as well, [5] assignment statements do not play a major role in LISP computations function definitions are commonly used assignments. [6] memory is managed in terms of linked structures and garbage collection, [7] LISP is interpreted and so programs can be developed and debugged in an extremely modular form line-by-line, [8] LISP programs easily interact with the host computer’s operating system and other programs, [9] the syntax for LISP is extremely simple and memorable, and [10] procedures from other languages can be incorperated into a copy of LISP. The purest form of LISP is SCHEME, industrial strength LISP is Common LISP [e.g., Gnu’s Austin/Kyoto Common LISP]. A consequence of these properties is that programs can be written for computations which seem almost magical. Programs can be made to alter, or eventually erase, themselves while executing their intended computation. Self-reproducing programs are short and easy. A single FIXED-POINT program can be written which, when given appropriate functions as arguments, performs a sort, a Newton Search, or writes a recursive program. Further, it is easy to rebuild LISP within itself into a call-by-name evaluator which avoids becomming entangled in unnecessary infinite computations. So, LISP programming is entertaining from a mathematical or computation-theoretic point of view. LISP is usually associated with artificial intelligence. But it goes beyond exotic tricks and a.i. to industrial-strength computing.
