AppleScript: The Definitive Guide

Preface

From a technological and historical perspective, AppleScript is one of the greatest innovations and distinguishing features of the Mac OS. The System provides not only a mechanism for applications to communicate with one another, ordering one another about, getting information from one another, and generally collaborating to avail themselves of one another’s strengths and abilities, but also a way for ordinary users to take advantage of this mechanism programmatically. The user can write and execute code in the AppleScript language as a way of automating the behavior of applications, reducing many steps to one, throwing the burden of repetition and calculation onto the computer, and combining the powers of multiple applications into a seamless united workflow. AppleScript is a labor-saving device that lets ordinary users program the computer for themselves; and, after all, labor-saving and programming are just what computers are all about.

Although AppleScript was long treated by Apple itself as something of an unwanted, troublesome step-child—and has even (according to apocryphal legend) at times come perilously near being tossed onto the scrapheap—it has lately prospered, and is now perhaps entering a kind of Golden Age. AppleScript has been embraced and acknowledged and is starting to take its rightful place in the firmament of Apple’s star technologies. It is noticed on Apple’s own web pages as a major aspect of Mac OS X (for example, see http://www.apple.com/macosx/overview/ ...
