详细说明： The AppleScript language evolved from a revolutionary language called HyperTalk, which was developed in 1987 by Bill Atkinson. HyperTalk, which was part of the programming environment called HyperCard, allowed you to write English-like sentences to accomplish yo ur tasks. Several commercial applications, most notably the popular game Myst, were developed in HyperCard. However, due to various marketing decisions, HyperCard and HyperTalk never gained widespread popularity and support. Like HyperTalk, AppleScript remained a language embraced by a relatively small circle of enthusi- asts. With the surge in popularity of Mac OS X, a powerful operating system based on UNIX, came a surge in the popularity of AppleScript. This was partly due to the fact that more and more applica- tions became scriptable, meaning you could talk to them from an AppleScript program. AppleScript was also found to be well suited for automating repetitive tasks in the workplace, a process known as workflow automation. Finally, AppleScript’s growth in popularity was partly owed to Apple’s recog- nition and adoption of AppleScript as a key technology component in Mac OS X. AppleScript is called a scripting language. Scripting languages are programming languages designed primarily to control or coordinate the operation of other programs. Examples of other popular scripting languages include JavaScript, Perl, Ruby, VBScript, the UNIX shell, and Python. On your Mac, a scripting language might ask the Safari browser to display a particular web page. Or it might ask iTunes to play a particular song. Scripting languages are also often used to coordi- nate the transfer of data between multiple applications to accomplish a task. So a script might con- tain code to go to the website for some data, put it into an Excel spreadsheet, and then email the spreadsheet to your boss. In the past, scripting languages were not well suited for accomplishing general-purpose program- ming tasks because they either lacked sufficient programming capabilities or were simply too ineffi- cient. However, the line between a scripting language and a general purpose programming language has become blurred over the years. In some situations, AppleScript can work just fine as a way to implement a solution to a general programming problem. ...展开收缩
