If you think of questions that are appropriate for this FAQ, or would like to improve an answer, please send email to us at lisp-faq@think.com. Topics Covered (Part 6): [6-0] General information about FTP Resources for Lisp [6-1] Repositories of Lisp Software [6-3] Publicly Redistributable Lisp Software [6-6] Formatting code in LaTeX [6-7] Where can I get an implementation of Prolog in Lisp? Search for \[#\] to get to question number # quickly. ---------------------------------------------------------------- Subject: [6-0] General information about FTP Resources for Lisp Remember, when ftping compressed or compacted files (.Z, .z, .arc, .fit, etc.) to use binary mode for retrieving the files. Files that end with a .z suffix were compressed with the patent-free gzip (no relation to zip). Source for gzip is available from: prep.ai.mit.edu:pub/gnu/{gzip-1.0.7.shar,gzip-1.0.7.tar} FTP sites for Lisp and Scheme interpreters and compilers are discussed in the answer to questions [4-0] and [4-2] and in the Scheme FAQ. See the entry on Macintosh Common Lisp in question [4-1] for information on the CD-ROM of Lisp code that Apple distributes with MCL 2.0. ---------------------------------------------------------------- Subject: [6-1] Repositories of Lisp Software There are several repositories of publicly redistributable and public domain Lisp code. The Lisp Utilities collection is accessible by anonymous ftp to any CMU CS machine (e.g., ftp.cs.cmu.edu [128.2.206.173]) or through AFS in the directory /afs/cs.cmu.edu/project/ai-repository/ai/lang/lisp/ If accessing this directory through anonymous ftp, it is important to "cd" to the directory using one atomic operation, as some of the superior directories on the path are protected from access by an anonymous ftp.

Constraint Programming and Non-determinism: SCREAMER: Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to Common Lisp such as CLOS, CLIM and Iterate. In several ways Screamer is more efficient than other implementations of backtracking languages. First, Screamer code is transformed into Common Lisp which can be compiled by the underlying Common Lisp system. Many competing implementations of nondeterministic Lisp are interpreters and thus are far less efficient than Screamer. Second, the backtracking primitives require fairly low overhead in Screamer. Finally, this overhead to support backtracking is only paid for those portions of the program which use the backtracking primitives. Deterministic portions of user programs pass through the Screamer to Common Lisp transformation unchanged. Since in practise, only small portions of typical programs utilize the backtracking primitives, Screamer can produce more efficient code than compilers for languages in which backtracking is more pervasive. Screamer is fairly portable across most Common Lisp implementations. It currently runs under Genera 8.1.1 and 8.3 on both Symbolics 36xx and Ivory machines, under Lucid 4.0.2 and 4.1 on Sun SPARC machines, under MCL 2.0 and 2.0p2 on Apple Macintosh machines, and under Poplog Common Lisp on Sun SPARC machines. It should run under any implementation of Common Lisp which is compliant with CLtL2 and with minor revision could be made to run under implementations compliant with CLtL1 or dpANS. Screamer is available by anonymous FTP from ftp.ai.mit.edu as the file /pub/screamer.tar.Z. Contact Jeffrey Mark Siskind for further information. Screamer is also available from the Lisp Utilities Repository. Databases: Postgres is an object-oriented database, and is available from postgres.berkeley.edu:/pub/postgres* It runs on DecStation 3100s, Sun3 (SunOs), Sun4 (Sparc), and Sequent Symmetry. Eliza and Similar Programs: See Peter Norvig's book and AI_ATTIC (question [6-1] above). The doctor.el is an implementation of Eliza for GNU-Emacs emacs-lisp. Invoke it with "Meta-X doctor" muLISP-87 (a MSDOS Lisp sold by Soft Warehouse) includes a Lisp implementation of Eliza. Implementations of ELIZA for other languages are mentioned in the AI FAQ. The original Parry (in MLISP for a PDP-10) is available in labrea.stanford.edu:/pub/parry.tar.Z. Other programs, such as RACTER, are listed in part 4 of the AI FAQ. Expert Systems: FOCL is an expert system shell and machine learning program written in Common Lisp.

SNePS is a semantic net implementation, available free after signing a license agreement. Contact shapiro@cs.buffalo.edu for more information. COLAB (COmpilation LABoratory) is a hybrid knowledge representation system emphasizing the horizontal and vertical compilation of knowledge bases. It is comprised of cooperating subsystems -- CONTAX, FORWARD, RELFUN and TAXON -- which deal with different knowledge representation and reasoning formalisms. Each subsystem can also be used as stand-alone system. CONTAX deals with constraint nets and constraint-propagation techniques. Relational knowledge in the form of Horn rules is processed by forward (FORWARD) and backward (RELFUN) chaining. Taxonomic knowledge is represented by intensional concept definitions which are automatically arranged in a subsumption hierarchy (TAXON). The COLAB software was developed at DFKI and the University of Kaiserslautern and runs in Common Lisp. (The subsystems have been tested in AKCL and Lucid CL, and possibly also Allegro CL and Symbolics CL.) All the subsystems are available free of charge for research purposes. o RELFUN is a logic-programming language with call-by-value (eager), non-deterministic, non-ground functions, and higher-order operations.

Languages and Alternate Syntaxes: Generalized Lisp (or Glisp for short) is a coordinated set of high level syntaxes for Common Lisp. Initially GLisp consists of three dialects: Mlisp, Plisp and ordinary Lisp, together with an extensible framework for adding others. Mlisp (Meta-Lisp) is an Algol-like syntax for people who don't like writing parentheses. For example, one can write print("abc", stream) instead of (print "abc" stream). Plisp (Pattern Lisp) is a pattern matching rewrite-rule language. Plisp is a compiler-compiler; its rules are optimized for writing language translators. All dialects may be freely intermixed in a file. The translators for all dialects are written in Plisp, as is the Glisp translator framework itself. Support routines for the translators are written in Mlisp and/or Lisp. All dialects are translated to Common Lisp and execute in the standard Common Lisp environment. Glisp is available by anonymous ftp from apple.com or ftp.apple.com:dts/mac/lisp/glisp.tar.Z GLISP runs in MCL and has to be modified for other Common Lisp implementations. CGOL is algol-like language that is translated into Lisp before execution. It was developed originally by Vaughn Pratt. A Common Lisp implementation of CGOL is available by anonymous ftp from peoplesparc.berkeley.edu:pub/cgol.1.tar.Z [128.32.131.14] (The number "1" may increase if newer versions are posted.) It was written by a UC Berkeley graduate student, Tom Phelps, as a term project, so there may still be some rough edges. There is a lot of documentation in the distribution, including the "original" CGOL memo (pratt.memo). For more information, contact Richard Fateman . StarLisp Simulator -- think.com:/cm/starlisp/starsim-f19-sharfile Simulates *Lisp, one of the programming langauges used to program the Connection Machine.

The Automatic Memoization Facility adds a practical memoization facility to Common Lisp. Automatic memoization is a technique by which an existing function can be transformed into one that "remembers" previous arguments and their associated results, yielding large performance gains for certain types of applications. This facility extends the ideas from Norvig's book into what is needed for a practical tool for us in large programs. It adds facilities for bookkeeping and timing, and lets you evaluate of the timing advantages of memoization, and save hash tables to disk for automatic reuse in later sessions. The code is available by anonymous ftp from archive.cs.umbc.edu:/pub/Memoization [130.85.100.53]. Contact Marty Hall for more information. The code includes an overview of memoization and its applications. PLisp - A Common Lisp front end to Postscript. This translates many Common Lisp functions to postscript as well as manage the environment and many lispisms (&optional and &rest arguments, multiple values, macros, ...).

Box 1316, D-5205 Sankt Augustin 1, FRG, email: juergen.kopp@gmd.de CommonORBIT (also called CORBIT) is an object-oriented extension of Common Lisp. It uses a prototype (classless) model of OOP, is easy to use and yet has many sophisticated features found also in KL-ONE type languages. CommonORBIT is a Common Lisp reimplementation of ORBIT, which was originally conceived by Luc Steels around 1981-1983. Because of its delegation-based rather than class-based inheritance, CommonORBIT offers extreme flexibility to define and change practically anything at run-time. Because of the generic functions, it fits well into regular Lisp code. It can co-exist with CLOS but remains completely separate. The source code of CommonORBIT is in the public domain and available by anonymous ftp from the Lisp Utilities Repository, ftp.cs.cmu.edu:user/ai/lang/lisp/ in the oop/non-clos/corbit/ subdirectory as the file corbit.tar.gz. Documentation is available as the files corbit.msword.hqx, corbit.ps or corbit.text. A stripped-down version of CORBIT, known as BOOPS (Beginner's Object-Oriented Programming System), is also available from the repository as boops.tar.Z. For further information, contact the author, Koenraad de Smedt . Parser Generators: Mark Johnson has written a LALR parser generator for Common Lisp. It is fairly small (about 500 lines of code) and can be found in the Lisp Utilities Repository above. IPG (Incremental Parser Generator) is available by email from Jan Rekers . It is an appendix to his thesis. It is written in LeLisp, but should be portable to other Lisp dialects. Zebu 2.8.5 is a parser generator for Common Lisp by Joachim H. Laubsch . It is an extention written in Common Lisp of the Scheme version. It generates a LALR(1) parsing table. To parse a string with a grammar, only this table and a driver need to be loaded. The present version of Zebu contains the ability to define several grammars and parsers simultaneously, a declarative framework for specifying the semantics, as well as efficiency related improvements. The current version compiles a grammar with 300 productions (including dumping of the tables to disk) in approx 2 minutes and 30 seconds on a HP 9000/370. This implimentation has been tested in Lucid CL, Allegro CL, and MCL 2.0b. The current version can also produce a generator in addition to a parser. A copy may be found on cambridge.apple.com:/pub/mcl2/contrib/zebu-2.2.tar.Z. Probabilistic Reasoning and Statistics: BELIEF is a Common Lisp implementation of the Dempster and Kong fusion and propagation algorithm for Graphical Belief Function Models and the Lauritzen and Spiegelhalter algorithm for Graphical Probabilistic Models.

It is available by anonymous ftp from ftp.stat.washington.edu (128.95.17.34), and by email from the author, Russell Almond . Contact the author at almond@statsci.com for information about a commercial version GRAPHICAL-BELIEF currently in the prototype stages. XLISP-STAT is an extensible statistics package which runs in XLISP. It has recently been ported to Common Lisp, and is available as umnstat.stat.umn.edu:/pub/xlispstat/CL/CLS1.0A1.tar.Z [128.101.51.1] The CL port does not yet include the lisp-stat dynamic graphics package, only the numerics. The XLisp version is available from the above site and several mirror sites, such as mac.archive.umich.edu, and runs on the Apple Macintosh, Unix systems running X11 (Vax, PMAX, Sun3, Encore Multimax, and Cray XMP), Sun workstations running SunView, and the Commodore Amiga.

It is particularly geared to the programming languages Scheme and Common Lisp, and has been tested in Chez Scheme, Common Lisp, MIT C Scheme, Elk, Scheme->C, SCM and UMB Scheme on Unix; and MIT C Scheme and SCM on MSDOS. The formatting of the code includes assigning appropriate fonts to the various tokens in the code (keywords, variables, constants, data), at the same time retaining the proper indentation when going to the non-monospace (non-typewriter) provided by TeX. SLaTeX comes with two databases that recognize the standard keywords/variables/constants of Scheme and Common Lisp respectively. These can be modified by the user using easy TeX commands. In addition, the user can inform SLaTeX to typeset arbitrary identifiers as specially suited TeX expressions (i.e., beyond just fonting them). The code-typesetting program SLaTeX is available by anonymous ftp from cs.rice.edu as the file public/dorai/slatex.tar.Z. Send bug reports to dorai@cs.rice.edu. SchemeWEB is a Unix filter that translates SchemeWEB source into LaTeX source or Scheme source. Originally developed for the Scheme dialect of Lisp, it can easily be used with most other dialects.
