There are several good Lisp introductions and tutorials: 1. David S. Touretzky "Common Lisp: A Gentle Introduction to Symbolic Computation" Benjamin/Cummings Publishers, Redwood City, CA, 1990. 592 pages. ISBN 0-8053-0492-4 ($42.95). Perhaps... Read More

John McCarthy developed the basics behind Lisp during the 1956 Dartmouth Summer Research Project on Artificial Intelligence. He intended it as an algebraic LISt Processing (hence the name) language for artificial intelligence work. Early... Read More

There are several books about Lisp programming style, including: 1. Molly M. Miller and Eric Benson "Lisp Style and Design" Digital Press, 1990. 214 pages, ISBN 1-55558-044-0, $26.95. How to write large Lisp programs and improve Lisp... Read More

CLX uses Unix sockets to communicate with the X window server. Look at the following files from the CLX distribution for a good example of using Unix sockets from Lisp: defsystem.lisp Lucid, AKCL, IBCL, CMU. socket.c, sockcl.lisp AKCL, IBCL ... Read More

In short, no single improvement you can make to your AutoCAD system will save you more time, effort, and money. You can spend thousands on the latest generation computers, the fastest video cards, and so on, but that won't make nearly as big a... Read More

Yes, absolutely, and the files are standard LISP code that will run on any AutoCAD system. Read More

By selecting general operations from the tools menu. You can think of the tools as building blocks - each tool corresponding to several lines of LISP code. The tools you use and the order in which you select them defines what your program does. Read More

You are free to come and go from the LISP Generator and do whatever you want in AutoCAD while you are in the middle of creating a program. There are helpful tools in case you forget things like the names of variables you defined. Read More

If you want, extremely complex. The LISP Generator utilizes nearly the entire AutoLISP language. There's no limit to how large your programs can be, and no limit to how complex they can be either. Even though most programs can be written in a... Read More

The newsgroup comp.lang.lisp exists for general discussion of topics related to the programming language Lisp. For example, possible topics can include (but are not necessarily limited to): announcements of Lisp books and products discussion of... Read More

Scheme is a dialect of Lisp that stresses conceptual elegance and simplicity. It is specified in R4RS and IEEE standard P1178. (See the Scheme FAQ for details on standards for Scheme.) Scheme is much smaller than Common Lisp; the specification is... Read More

Many Lisp functions can be defined in terms of other Lisp functions. For example, CAAR can be defined in terms of CAR as (defun caar (list) (car (car list))) It is then natural to ask whether there is a "minimal" or smallest set of primitives... Read More

There is no portable way in Common Lisp of determining whether a file is a directory or not. Calling DIRECTORY on the pathname will not always work, since the directory could be empty. For UNIX systems (defun DIRECTORY-P (pathname) (probe-file ... Read More

There is no standard for dumping a Lisp image. Here are the commands from some lisp implementations: Lucid: DISKSAVE Symbolics: Save World [CP command] CMU CL: SAVE-LISP Franz Allegro: EXCL:DUMPLISP (documented) SAVE-IMAGE (undocumented) ... Read More

In implementations that provide a foreign function interface as described above, there is also usually a "callback" mechanism. The programmer may associate a foreign language function name with a Lisp function. When a foreign object file or... Read More

A Lisp machine (or LISPM) is a computer which has been optimized to run lisp efficiently and provide a good environment for programming in it. The original Lisp machines were implemented at MIT, with spinoffs as LMI (defunct) and Symbolics ... Read More

Most Lisp implementations for systems where Lisp is not the most common language provide a "foreign function" interface. As of now there has been no significant standardization effort in this area. They tend to be similar, but there are enough... Read More

LG3 writes easy-to-read, fully indented AutoLISP programs loaded with detailed comments in English that explain what all of the LISP code is doing. The files are standard ".LSP" files. You can view, edit, or print them with any editor, and run them... Read More

Books about Lisp implementation include: 1. John Allen "Anatomy of Lisp" McGraw-Hill, 1978. 446 pages. ISBN 0-07-001115-X Discusses some of the fundamental issues involved in the implemention of Lisp. 2. Samuel Kamin " Programming ... Read More
