AppleScript is a scripting language developed by Apple that empowers users to control both scriptable Macintosh applications and various components of macOS directly. It enables the creation of scripts, which are sets of written instructions designed to automate repetitive tasks, merge features from different scriptable applications, and construct intricate workflows. The 2.0 version of AppleScript is compatible with scripts created for any earlier version from 1.1 to 1.10.7, as well as any scripting addition made for AppleScript 1.5 or newer in macOS and any scriptable application from Mac OS v7.1 onward. A scriptable application is defined as one that can be manipulated through a script, meaning it can respond to inter-application messages, known as Apple events, that are sent when a script command is aimed at it. Although AppleScript itself offers a limited set of commands, it establishes a framework that allows the integration of numerous task-specific commands supplied by both scriptable applications and the scriptable components of macOS. This flexibility makes AppleScript a valuable tool for enhancing productivity and streamlining various computing tasks.

ZenScript was developed from MineTweaker to provide a straightforward programming language that enables users with little to no coding experience to execute basic commands by adhering to its tutorials. Initially, MineTweaker utilized a simple system that parsed one line at a time, but it soon became evident that this approach lacked the necessary flexibility, prompting the creation of a more adaptable parsed language. While this new language functioned adequately, it suffered from inefficiency as each value was unnecessarily encapsulated within its own object. In contrast, ZenScript supports a combination of typed and typeless functionality, eliminating the need for users to specify types explicitly; the compiler intelligently infers types when feasible and defaults to typeless behavior when the type remains uncertain. However, in most scenarios, the type is clearly defined, allowing execution to proceed at the speed of native Java. With the incorporation of types, users can also document and enforce them effectively, enhancing the overall usability and reliability of the language. This evolution towards a more robust scripting environment demonstrates the ongoing commitment to making programming accessible to a wider audience.
