Object Lisp was a computer programming language, a dialect of the Lisp language. It was an object-oriented extension for the Lisp dialect Lisp Machine Lisp, designed by Lisp Machines, Inc. Object Lisp was also an early example of prototype-based programming.
It was seen as a competitor to other object-oriented extensions to Lisp at around the same time such as Flavors, in use by Symbolics, Common Objects developed by Hewlett-Packard, and CommonLoops, in use by Xerox.
Object Lisp was also used in early versions of Macintosh Common Lisp. There, the user interface toolkit was written using Object Lisp.
Famous quotes containing the words object and/or lisp:
“It is the nature of our desires to be boundless, and many live only to gratify them. But for this purpose the first object is, not so much to establish an equality of fortune, as to prevent those who are of a good disposition from desiring more than their own, and those who are of a bad one from being able to acquire it; and this may be done if they are kept in an inferior station, and not exposed to injustice.”
—Aristotle (384–322 B.C.)
“Taught me my alphabet to say,
To lisp my very earliest word,”
—Edgar Allan Poe (1809–1849)
