Code Required for Classwork

This section contains links to code that you will need to do homework assignments.

• a link of great importance :-) coming soon

Code from Paul Graham

The following code comes straight from the author of our textbook:

• code from ANSI Common Lisp -- [local mirror]

• code from On Lisp, Graham's more advanced book [local mirror]

You will also find many useful Lisp resources at Paul Graham's Lisp Resources page. It offers a lots of cool links!)

Helpful Common Lisp Links

This section contains links to sites of general interest. Feel free to read and use anything you encounter here.

• a handy guide for using emacs with Common Lisp

• the full text of Common Lisp: The Language, by Guy Steele

  I especially encourage you to become familiar with this, the Common Lisp bible. Your textbook does not tell you everything you will want to know about Common Lisp, nor will I!

• the CMU Common Lisp Repository

  This site contains all sorts of goodies related to Common Lisp. I have spent (wasted? :-) many hours exploring here.

• free and shareware implementations of Common Lisp

  This CMU repository page has oodles of useful links. If you would like to have Common Lisp running on your own personal computer, then explore the options available there. At this point in time, I would recommend the following implementations...

  • CMU Common Lisp (CMUCL) is installed on the Linux boxes in the local labs, 339 Wright and 112 Wright. It is a free, complete, and fast implementation. Many AI researchers I know recommend it highly.

  • Macintosh Common Lisp, from DigiTool offers a marvelous development environment and a complete Common Lisp implementation, but its free version is available for a limited time only (four weeks, the last time I checked).

  • PowerLisp is a nice Macintosh implementation, but it does not offer a a complete Common Lisp repertoire.

  • GCL for Unix- and Windows-based machines. We have had GCL running on the Linux and Windows boxes in 339 Wright and 112 Wright in the past, but i don't know its current status there. GCL is an almost complete implementation of Common Lisp, and we are able to add most of what we need to make it whole. It does not have a nice development environment, and the interpreter can be hard to work with, but it can be connected to emacs to provide a reasonable working environment.

  • Allegro CL Lite for Linux-, FreeBSD-, and Windows-based machines. Allegro Common Lisp is a premiere commercial Lisp environment, and their free version is quite nice.

  • Xanalys's LispWorks Personal Edition runs on Linux and MS Windows. I have never used it, but it comes to me highly recommended by other AI faculty.

• CLiCC, a Common Lisp-to-C compiler.

• frequently-asked questions listings for Common Lisp and CLOS

• Marty Hall's Common Lisp Links

• Kent Pitman's Common Lisp Info site. Kent has been active for 25 years in the design of Common Lisp, Common Lisp interpreters, and Common Lisp applications.
