School of Computer Science Carnegie Mellon University Pittsburgh, PA 15213 This is a revised version of Technical Report CMU-CS-87-156. Companion to Common Lisp: The Language Abstract CMU Common Lisp is an implementation of Common Lisp that currently runs on the IBM RT PC under Mach, a Berkeley Unix 4.3 binary compatible operating system. This document describes the implementation dependent choices made in developing this implementation of Common Lisp. Also, several extensions have been added, including the proposed error system, a stack crawling debugger, a stepper, an interface to Mach system calls, a foreign function call interface, the ability to write assembler language routines, and other features that provide a good environment for developing Lisp code.

The Machine That Builds Itself: How the Strengths of Lisp Family
Khomtchouk et al. OPINION NOTE The Machine that Builds Itself: How the Strengths of Lisp Family Languages Facilitate Building Complex and Flexible Bioinformatic Models Bohdan B. Khomtchouk1*, Edmund Weitz2 and Claes Wahlestedt1 *Correspondence: [email protected] Abstract 1Center for Therapeutic Innovation and Department of We address the need for expanding the presence of the Lisp family of Psychiatry and Behavioral programming languages in bioinformatics and computational biology research. Sciences, University of Miami Languages of this family, like Common Lisp, Scheme, or Clojure, facilitate the Miller School of Medicine, 1120 NW 14th ST, Miami, FL, USA creation of powerful and flexible software models that are required for complex 33136 and rapidly evolving domains like biology. We will point out several important key Full list of author information is features that distinguish languages of the Lisp family from other programming available at the end of the article languages and we will explain how these features can aid researchers in becoming more productive and creating better code. We will also show how these features make these languages ideal tools for artificial intelligence and machine learning applications. We will specifically stress the advantages of domain-specific languages (DSL): languages which are specialized to a particular area and thus not only facilitate easier research problem formulation, but also aid in the establishment of standards and best programming practices as applied to the specific research field at hand. DSLs are particularly easy to build in Common Lisp, the most comprehensive Lisp dialect, which is commonly referred to as the “programmable programming language.” We are convinced that Lisp grants programmers unprecedented power to build increasingly sophisticated artificial intelligence systems that may ultimately transform machine learning and AI research in bioinformatics and computational biology. -
Omnipresent and Low-Overhead Application Debugging
Omnipresent and low-overhead application debugging Robert Strandh [email protected] LaBRI, University of Bordeaux Talence, France ABSTRACT application programmers as opposed to system programmers. The state of the art in application debugging in free Common The difference, in the context of this paper, is that the tech- Lisp implementations leaves much to be desired.

Instead, throughout this application programmer to examine the control stack when paper, we assume that, as far as the application programmer an unhandled error is signaled. Most such implementations do is concerned, the semantics of the code generated by the not allow the programmer to set breakpoints (unconditional compiler corresponds to that of the source code. or conditional), nor to step the program after it has stopped.

The Embeddable Common Lisp
ACM Lisp Pointers 8(1), 1995, 30-41 The Embeddable Common Lisp Giuseppe Attardi Dipartimento di Informatica, Universit`adi Pisa Corso Italia 40, I-56125 Pisa, Italy net: [email protected] Abstract The Embeddable Common Lisp is an implementation of Common Lisp designed for being embeddable within C based applications. ECL uses standard C calling conventions for Lisp compiled functions, which allows C programs to easily call Lisp functions and viceversa. No foreign function interface is required: data can be exchanged between C and Lisp with no need for conversion. ECL is based on a Common Runtime Support (CRS) which provides basic facilities for memory management, dynamic loading and dumping of binary images, support for multiple threads of execution. The CRS is built into a library that can be linked with the code of the application. ECL is modular: main modules are the program development tools (top level, debugger, trace, stepper), the compiler, and CLOS. A native implementation of CLOS is available in ECL: one can configure ECL with or without CLOS. A runtime version of ECL can be built with just the modules which are required by the application. 1 Introduction As applications become more elaborate, the facilities required to build them grow in number and sophistica- tion. Each facility is accessed through a specific package, quite complex itself, like in the cases of: modeling, simulation, graphics, hypertext facilities, data base management, numerical analysis, deductive capabilities, concurrent programming, heuristic search, symbolic manipulation, language analysis, special device control. Reusability is quite a significant issue: once a package has been developed, tested and debugged, it is un- desirable having to rewrite it in a different language just because the application is based in such other language. -

Programming Environments John Foderaro In
Programming Environments John Foderaro In this issue we feature a description of Delph! Common Lisp, an enhanced version of Kyoto Common Lisp. Company: Delphi S.p.A. Via della Vetraia, 11 1-55049 Viareggio, Italy tel: + 39 (584) 395225 fax: + 39 (584) 395366 tlx: 501542 DELPlll I Product name: Delphi Common Lisp Version of product described: All versions. This version available when: This year. Contact Delphi for more information. Hardware available on: Sun 3, Sun 4, Sun 386i, general 386-based machines running Unix system V. Available on a wide variety of hardware and operating systems in the near future. Delphi Common Lisp is a full implementation of Common Lisp than runs on a range of general-purpose computers. DCL provides several major facilities on top of the Common Lisp standard to provide a more complete and powerful programming language including - Common Lisp Object System, in complete accordance with the ANSI X3J 13 subcommittee proposal. - CLX, the emerging standard binding between Common l,isp and the X Window system "client" functionality. It's implemented entirely in Lisp (doesn't go through XLib) and provides direct access from Lisp to all X Window client functions. - "Multithread" facility to create and control concurrent threads of program execution. Useful for U.I. design and other applications where interrupts can come from a variety of sources as well as parallel processing research. - ttigh productivity facilities like ZetaLisp LOOP macro, Symbolics-style DEFSYSTEM, autoioad facility, EMACS editor interface Influence: The Common Lisp component of DCL is based on Kyoto Common Lisp, meaning that it's extremely portable and, now, performs quite well. -
