[编辑] 简介

Smalltalk

Smalltalk 发行于 1972年(50岁),开发始于 1969 年,The Story of Smalltalk

  • Smalltalk is a vision
  • Smalltalk has few concepts
  • Smalltalk is an environment
  • Smalltalk is a big system
  • Smalltalk as an operating system

Smalltalk 不仅仅是一门语言。Smalltalk-80 最初是作为一个完整的操作系统交付的,旨在运行在一台裸机上。Smalltalk-80 包含 virtual machine 规范。

I like it... It’s nice and clean and simple and pretty. Nice stuff!

— Alan Kay

Smalltalk 是 70 年代初期美国 XEROX 公司开发的,它不仅是一门编程语言,一个窗口系统,也是一个完整的编程环境,一个集编程、调试、运行和输出为一体的统一环境。

Smalltalk 创立了面向对象的思想并一直沿用至今。

Smalltalk is the consummate teaching language, Smalltalk is OOP done right.

The best way to predict the future is to invent it! -Alan Kay

Smalltalk,被公认为历史上第二个面向对象的程序设计语言,和第一个真正的集成开发环境(IDE)。

Smalltalk对其它众多的程序设计语言的产生起到了极大的推动作用,主要有:C++,C#,Objective-C,Actor,JavaRuby等。90年代的许多软件开发思想得利于Smalltalk,例如设计模式、敏捷编程和代码重构等。

Dynamically Typed + Live Environment

DynamicType (SelfType, ClassType, InstanceType)

Live Typing Automatic Type Annotation for Dynamically Typed Languages]

Smalltalk 杀手级功能:

  • 编程语言虚拟机机制
  • 基于镜像(Image-based)的持久性
  • 对象,一切都是对象,对象之间只通过消息进行交流(最纯粹的OO,也是最早的一个)
  • Live(实时)编程
  • 先进的调试技术,如即时修改代码(on-the-fly code changes)
  • 简单、不混乱(uncluttered)的 IDE 界面
  • 特定领域语言(DSL)是 Smalltalk 唯一的工作方式,程序员必须使用对该领域自然的语言和符号来关注问题领域。
