  • 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.

  • Lisp Tutorial
    Gene Kim 9/9/2016 CSC 2/444 Lisp Tutorial About this Document This document was written to accompany an in-person Lisp tutorial. Therefore, the information on this document alone is not likely to be sufficient to get a good understanding of Lisp. However, the functions and operators that are listed here are a good starting point, so you may look up specifications and examples of usage for those functions in the Common Lisp HyperSpec (CLHS) to get an understanding of their usage. Getting Started Note on Common Lisp Implementations I will use Allegro Common Lisp since it is what is used by Len (and my research). However, for the purposes of this class we won’t be using many (if any) features that are specific to common lisp implementations so you may use any of the common lisp implementations available in the URCS servers. If you are using any libraries that are implementation-specific for assignments in this class, I would strongly urge you to rethink your approach if possible. If we (the TAs) deem any of these features to be solving to much of the assigned problem, you will not receive full credit for the assignment. To see if a function is in the Common Lisp specifications see the Common Lisp HyperSpec (CLHS). Simply google the function followed by “clhs” to see if an entry shows up. Available Common Lisp implementations (as far as I know): - Allegro Common Lisp (acl or alisp will start an Allegro REPL) - CMU Common Lisp (cmucl or lisp will start a CMUCL REPL) - Steel Bank Common Lisp (sbcl will start an SBCL REPL) IDE/Editor It is not important for this class to have an extensive IDE since we will be working on small coding projects.

The more-or-less official documentation for format is at the Common Lisp Hyperspec[X3J]. There is a complete if terse description of it in Paul Graham’s ANSI Common Lisp[Gra96], but my favorite description of format is in Franz’s Common Lisp The Reference[Inc88]. 1 Knowing the details of how something works isn’t the same as knowing how to use it well. Good applications of format aren’t obvious from its documentation. Thus this article. 2 Wanted & To Do Read the original article about format[Wat89]. Possibly incorporate ideas from it, or refer to them. Definitely refer to it in this article so people know it exists. (I didn’t know it existed at all even though I searched the web for such articles before I wrote this one.
