  • The Evolution of Lisp
    1 The Evolution of Lisp Guy L. Steele Jr. Richard P. Gabriel Thinking Machines Corporation Lucid, Inc. 245 First Street 707 Laurel Street Cambridge, Massachusetts 02142 Menlo Park, California 94025 Phone: (617) 234-2860 Phone: (415) 329-8400 FAX: (617) 243-4444 FAX: (415) 329-8480 E-mail: [email protected] E-mail: [email protected] Abstract Lisp is the world’s greatest programming language—or so its proponents think. The structure of Lisp makes it easy to extend the language or even to implement entirely new dialects without starting from scratch. Overall, the evolution of Lisp has been guided more by institutional rivalry, one-upsmanship, and the glee born of technical cleverness that is characteristic of the “hacker culture” than by sober assessments of technical requirements. Nevertheless this process has eventually produced both an industrial- strength programming language, messy but powerful, and a technically pure dialect, small but powerful, that is suitable for use by programming-language theoreticians. We pick up where McCarthy’s paper in the first HOPL conference left off. We trace the development chronologically from the era of the PDP-6, through the heyday of Interlisp and MacLisp, past the ascension and decline of special purpose Lisp machines, to the present era of standardization activities. We then examine the technical evolution of a few representative language features, including both some notable successes and some notable failures, that illuminate design issues that distinguish Lisp from other programming languages. We also discuss the use of Lisp as a laboratory for designing other programming languages. We conclude with some reflections on the forces that have driven the evolution of Lisp.

McClain Submitted to the Department of Electrical Engineering and Computer Science on August 5th, 1994, in partial fulfillment of the requirements for the degrees of Master of Science in Electrical Engineering and Computer Science and Bachelor of Science in Electrical Engineering Abstract In this thesis I describe LOOP, a new architecture for the efficient execution of pro- grams written in Lisp like languages. LOOP allows Lisp programs to run at high speed without sacrificing safety or ease of programming. LOOP is a 64 bit, long in- struction word architecture with support for generic arithmetic, 64 bit tagged IEEE floats, low cost fine grained read and write barriers, and fast traps. I make estimates for how much these Lisp specific features cost and how much they may speed up the execution of programs written in Lisp.

In this paper we inuoked via normal Lisp function call. Methods are present the linguistic mechanisms that we have viewed as partial descriptions of procedures.

White collection on Common Lisp contains material relating to the development and standardization of the programming language Common Lisp and, more generally, the Lisp family of programming languages. Records date from 1963 to 2012, with the bulk of the material ranging from 1978 to 1995, when White was working at MIT’s Artificial Intelligence Laboratory, Xerox PARC (Palo Alto Research Center), Lucid, and Harlequin Group. Throughout many of these positions, White was serving on the X3J13 Committee to formalize a Common Lisp standard, which aimed to combine and standardize many previous dialects of Lisp. This collection consists of conference proceedings, manuals, X3J13 Committee correspondence and meeting minutes, notebooks, technical papers, and periodicals documenting White’s work in all of these roles. Other dialects of Lisp--especially MAClisp--are also major focuses of the collection.

  • Basic Lisp Techniques
    Basic Lisp Techniques David J. Cooper, Jr. February 14, 2011 ii 0Copyright c 2011, Franz Inc. and David J. Cooper, Jr. Foreword1 Computers, and the software applications that power them, permeate every facet of our daily lives. From groceries to airline reservations to dental appointments, our reliance on technology is all-encompassing. And, it’s not enough. Every day, our expectations of technology and software increase: • smart appliances that can be controlled via the internet • better search engines that generate information we actually want • voice-activated laptops • cars that know exactly where to go The list is endless. Unfortunately, there is not an endless supply of programmers and developers to satisfy our insatiable appetites for new features and gadgets. Every day, hundreds of magazine and on-line articles focus on the time and people resources needed to support future technological expectations. Further, the days of unlimited funding are over. Investors want to see results, fast. Common Lisp (CL) is one of the few languages and development options that can meet these challenges. Powerful, flexible, changeable on the fly — increasingly, CL is playing a leading role in areas with complex problem-solving demands. Engineers in the fields of bioinformatics, scheduling, data mining, document management, B2B, and E-commerce have all turned to CL to complete their applications on time and within budget. CL, however, no longer just appropriate for the most complex problems. Applications of modest complexity, but with demanding needs for fast development cycles and customization, are also ideal candidates for CL. Other languages have tried to mimic CL, with limited success.

  • Common Lisp Object System
    Common Lisp Object System by Linda G. DeMichiel and Richard P. Gabriel Lucid, Inc. 707 Laurel Street Menlo Park, California 94025 (415)329-8400 [email protected] [email protected] with Major Contributions by Daniel Bobrow, Gregor Kiczales, and David Moon Abstract The Common Lisp Object System is an object-oriented system that is based on the concepts of generic functions, multiple inheritance, and method combination. All objects in the Object System are instances of classes that form an extension to the Common Lisp type system. The Common Lisp Object System is based on a meta-object protocol that renders it possible to alter the fundamental structure of the Object System itself. The Common Lisp Object System has been proposed as a standard for ANSI Common Lisp and has been tentatively endorsed by X3J13. Common Lisp Object System by Linda G. DeMichiel and Richard P. Gabriel with Major Contributions by Daniel Bobrow, Gregor Kiczales, and David Moon 1. History of the Common Lisp Object System The Common Lisp Object System is an object-oriented programming paradigm de- signed for Common Lisp. Over a period of eight months a group of five people, one from Symbolics and two each from Lucid and Xerox, took the best ideas from CommonLoops and Flavors, and combined them into a new object-oriented paradigm for Common Lisp. This combination is not simply a union: It is a new paradigm that is similar in its outward appearances to CommonLoops and Flavors, and it has been given a firmer underlying semantic basis. The Common Lisp Object System has been proposed as a standard for ANSI Common Lisp and has been tentatively endorsed by X3J13.
