также SmallTalk (дословно "короткий разговор") [язык программирования] Смолток его разработали в 1972 г. Алан Кей (Alan Kay) и сотрудники исследовательской группы Software Concept Group фирмы Xerox PARK (США). Первый объектно-ориентированный язык сверхвысокого уровня. Характеризуется интерактивным графическим взаимодействием с пользователем. В нём использованы концепции классов и сообщений из языка Simula-67. В своём развитии язык прошел следующие версии: Smalltalk-72, Smalltalk-74, Smalltalk-76, Smalltalk-78, Smalltalk-80, GNU Smalltalk, Smalltalk/V Смотри также: class, message, OOL, OOP
The pioneering object-oriented programming system developed in 1972 by the Software Concepts Group, led by Alan Kay, at Xerox PARC between 1971 and 1983. It includes a language, a programming environment, and an extensive object library. Smalltalk took the concepts of class and message from Simula-67 and made them all-pervasive. In Smalltalk, any message can be sent to any object. The recipient object itself decides (based on the message name, also called the "message selector") how to respond to the message. Because of that, the multiple inheritance system included in the early versions of Smalltalk-80 appeared to be unused in practice. All modern implementations have single inheritance, so each class can have at most one superclass. Early implementations were interpreted but all modern ones use dynamic translation (JIT). Early versions were Smalltalk-72, Smalltalk-74, Smalltalk-76 (inheritance taken from Simula, and concurrency), and Smalltalk-78, Smalltalk-80. Other versions include Little Smalltalk, Smalltalk/V, Kamin's interpreters. Current versions are VisualWorks, Squeak, VisualAge, Dolphin Smalltalk, Object Studio, GNU Smalltalk.
