Scheme is a dialect of the Lisp family of programming languages. Scheme was created during the 1970s at the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) and released by its developers, Guy L. Steele and Gerald Jay Sussman , via a series of memos now known as the Lambda Papers .
Scheme dialect developed in the early 1980s by Jonathan A. Rees, Kent M. Pitman, and Norman I. Adams of Yale University as an experiment in language design and implementation [35] TXR: 2009: Kaz Kylheku: Consists of a Lisp dialect (TXR Lisp) and a pattern language for processing text (TXR Pattern Language) [36]
In the Scheme dialect, which favors the functional style, the names of destructive functions are marked with a cautionary exclamation point, or "bang"—such as set-car! (read set car bang), which replaces the car of a cons. In the Common Lisp dialect, destructive functions are commonplace; the equivalent of set-car! is named rplaca for ...
Scheme was the first dialect of Lisp to choose lexical scope. It was also one of the first programming languages after Reynold's Definitional Language [15] to support first-class continuations. It had a large impact on the effort that led to the development of its sister-language, Common Lisp, to which Guy Steele was a contributor. [16]
The magazine said that the book was not easy to read, but that it would expose experienced programmers to both old and new topics. [ 8 ] A review of SICP as an undergraduate textbook by Philip Wadler noted the weaknesses of the Scheme language as an introductory language for a computer science course. [ 9 ]
The goal of this standards effort was to define a small, core language to help bridge the gap between differing dialects of Lisp. It attempted to accomplish this goal by studying primarily Common Lisp , EuLisp , Le Lisp , and Scheme and standardizing only those features shared between them.
Language[2] Lisp (programming language) Lisp (historically LISP, an abbreviation of "list processing") is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation.[3] Originally specified in the late 1950s, it is the second-oldest high-level programming language still in common use, after
