Editing Common Lisp (section)

==History==

Work on Common Lisp started in 1981 after an initiative by ARPA manager Bob Engelmore to develop a single community standard Lisp dialect.<ref>{{cite web|url=https://www.cs.cmu.edu/afs/cs/project/ai-repository/ai/lang/lisp/doc/history/cl.txt|title=Roots of "Yu-Shiang Lisp", Mail from Jon L White, 1982|website=cmu.edu}}</ref> Much of the initial language design was done via electronic mail.<ref>{{cite web|url=http://cl-su-ai.lisp.se/maillist.html|title=Mail Index|website=cl-su-ai.lisp.se}}</ref><ref>[http://ccs.mit.edu/papers/CCSWP150.html Knee-jerk Anti-LOOPism and other E-mail Phenomena: Oral, Written, and Electronic Patterns in Computer-Mediated Communication, JoAnne Yates and Wanda J.

The first language documentation was published in 1984 as [[Common Lisp the Language]] (known as CLtL1), first edition. A second edition (known as CLtL2), published in 1990, incorporated many changes to the language, made during the ANSI Common Lisp standardization process: extended LOOP syntax, the Common Lisp Object System, the Condition System for error handling, an interface to the pretty printer and much more. But CLtL2 does not describe the final ANSI Common Lisp standard and thus is not a documentation of ANSI Common Lisp. The final ANSI Common Lisp standard then was published in 1994. Since then no update to the standard has been published. Various extensions and improvements to Common Lisp (examples are Unicode, Concurrency, CLOS-based IO) have been provided by implementations and [[Library (computing)|libraries]].
