The lion's share of Bruce Perry's treatment of the language explains, with a minimum of frills, how each aspect of the AppleScript language works. This is classic O'Reilly, and it works well. For each statement (such as "with transaction") and reserved word (such as "anything"), you get a concise statement of syntax, examples of proper usage, an explanation of what's going on, and caveats where they're required. Classes--the one that the Finder uses to represent folders, for instance--are presented with each of their properties and methods listed alphabetically, and explained, usually with an example. The scripting techniques that are specific to applications, such as Sherlock 2 and the Speech Listener--are similar, with commands and classes presented alphabetically with all options presented explicitly. This book is a comprehensive treatment of a really useful language. Check out Learning Carbon and Learning Cocoa if you want to delve deeper into Mac OS programming. --David Wall

Topics covered:

• The core of the AppleScript language
• The scriptable aspects of Mac OS versions 9, 9.1, and X
• Scripting applications
• Scripting for network configuration
• Scripting additions

• Detailed coverage of AppleScript Version 1.4 and beyond on Mac OS 9 and Mac OS X.
• Complete descriptions of AppleScript language features, such as data types, flow-control statements, functions, object-oriented features (script objects and libraries), and other syntactical elements.
• Descriptions and hundreds of code samples on programming the various "scriptable" system components, such as the Finder, File Sharing, File Exchange, Network scripting, Web scripting, Apple System Profiler, the ColorSync program, and the numerous powerful language extensions called "osax" or scripting additions. Most other AppleScript books are hopelessly out of date. AppleScript in a Nutshell covers the latest updates and improvements with practical, easy to understand tips, including:
• Using AppleScript as a tool for distributed computing, an exciting development that Apple Computer calls "program linking over IP." Programmers can now do distributed computing with Macs over TCP/IP networks, including controlling remote applications with AppleScript and calling AppleScript methods on code libraries that are located on other machines.
• Using the Sherlock find application to automate web and network searching.
• Insights on scripting new Apple technologies such as Apple Data Detectors, Folder Actions, Keychain Access, and Apple Verifier. AppleScript in a Nutshell is a high-end handbook at a low-end price--an essential desktop reference that puts the full power of this user-friendly programming language into every AppleScript user's hands.
