Apple
AppleScript is a scripting language created by Apple. It allows users to directly control scriptable Macintosh applications, as well as parts of macOS itself. You can create scripts, and sets of written instructions, to automate repetitive tasks, combine features from multiple scriptable applications, and create complex workflows. AppleScript 2.0 can use scripts developed for any version of AppleScript from 1.1 through 1.10.7, any scripting addition created for AppleScript 1.5 or later for macOS, and any scriptable application for Mac OS v7.1 or later. A scriptable application is one that can be controlled by a script. For AppleScript, that means being responsive to inter-application messages, called Apple events, sent when a script command targets the application. AppleScript itself provides a very small number of commands, but it provides a framework into which you can plug many task-specific commands, those provided by scriptable applications and scriptable parts of macOS.Starting Price: Free -

Pine Script
TradingView
Pine Script® is TradingView’s programming language. It allows traders to create their own trading tools and run them on our servers.

It’s our explicit goal to keep Pine Script® accessible and easy to understand for the broadest possible audience. Pine Script® is cloud-based and therefore different from client-side programming languages. While we likely won’t develop Pine Script® into a full-fledged language, we do constantly improve it and are always happy to consider requests for new features. Because each script uses computational resources in the cloud, we must impose limits in order to share these resources fairly among our users.Starting Price: Free -

ZenScript
CraftTweaker
ZenScript originated from MineTweaker where a simple programming language is needed to allow users without programming knowledge to be able to execute simple commands by following the tutorials for it. Originally MineTweaker had a simple one-line-at-a-time parsed scripting system, but it quickly became clear that it wasn't flexible enough, so a simple parsed language was created. This parsed language worked quite well but was very inefficient as each value was wrapped into its own object. ZenScript allows mixed typed and typeless behavior. You don't need to define types anywhere, the compile will infer them where possible and exhibit typeless behavior when the type is effectively unknown. In nearly all the cases, the type is perfectly known and execution runs at native Java speed. Since there are types, they can be documented and enforced.Starting Price: Free -
