![]() No matter how wonderful an app might be, if its developers haven’t provided scripting hooks into its data and features, you cannot engineer them in yourself. Two inherent problems limit what you can achieve in AppleScript: the support built into each application, and the fact that common GUI devices such as dialogs are not fully controlled by AppleEvents. When run, the intermediate code works through macOS to fire off AppleEvents (AEvents) to trigger the target applications to perform the actions. When you’re ready to test your script, it compiles into intermediate code, and the editor automatically checks, formats and colours your source code, reporting any errors that it finds. Unlike the great majority of programming languages, punctuation marks are used sparsely in AppleScript, making it considerably easier to write code that works, rather than tripping over a missing semicolon. It first asks macOS whether it knows that Mail is running, and depending on the answer it executes the code that you insert where the comments (prefaced by ‘-‘ characters) are placed. You might use that code to set up a script that interacts with the Mail application. ![]() Set mailIsRunning to application process "Mail" exists This complexity arises because AppleScript is in fact an object-orientated language as sophisticated as Objective-C, used by pro Mac developers do not be deceived by its apparently relaxed and informal style, with examples such as There are also events, notifications that something has occurred, such as a disk being mounted, or a file being added to a folder. View a dictionary and you will see what at first appears very complex: long listings of data types (classes, which are instantiated into objects when they are used), such as application, window, file, and text, and methods (commands) that are applied to the objects of each class. Rather than having to locate additional documentation sets specific to each application, all a scripter needs do is open the dictionary. Those, and the suites of additional commands that bring joy to the scripter, are documented in standard formats within an application’s dictionary, which can be browsed by Script Editor and other tools. ![]() At their most complex, they can automate intricate and repetitive tasks that are messy in a GUI.Īs a minimum, every application supports a small core of commands to play clean with the Finder and macOS. At their simplest, these can open a document and print it, for instance. The concept behind AppleScript is simple: scripts that compile to a series of instructions for despatch by macOS to their destination application, which in turn is controlled by those commands to perform a co-ordinated sequence of functions. AppleScript is designed to give users and developers direct control over the applications on their Macs, and was quickly supported by professional products such as QuarkXPress, as well as Apple’s own rich software portfolio. The release of Apple’s System 7 Pro, version 7.1.1, in October 1993 brought a new programming language, based on the ‘natural’ English-like syntax of HyperTalk, HyperCard’s scripting language. As an introduction to future articles about Shortcuts and how to get more out of it, this article provides an overview of the last 28 years of scripting the Mac. With the imminent release of macOS Monterey comes a new system for scripting and automating the Mac: Shortcuts. ![]()
