Scarlet

Scarlet is an interpreted programming language built for Minecraft on the Fabric Loader. It is designed to allow quick prototyping for server scripting & content creation.

What is Scarlet used for?

Scarlet makes it easy to add new scripted content to the game without prior Java experience. My primary target audience is (1) people looking to have fun with friends on private servers, and (2) people who need a tool for scripting Minecraft video content or minigames (which isn't a strong point of Java).

Scarlet is also a viable option for modpack event scripting, but for anything serious being shipped to production, I would recommend KubeJS instead.

Give me an example!

Scarlet code goes in your /run/scarlet/ directory with the .scarlet file extension. Reload all Scarlet code by pressing the 'R' key. How about we print a simple greeting when a player joins the server?

Oops! I made a mistake while typing this out and wrote "on join server" instead, you say, wondering how Scarlet will handle it. Scarlet has a friendly error logging system that will show you exactly where the offending code lies:

Give me more examples!

You can find a collection of Scarlet example scripts in the /example_scripts/ directory of this repository. Here are a few of our favorites:

• File IO
• Iteration & Delays
• Java Property Resolving

A Note on Stability

Scarlet is, first and foremost, a fun educational exercise for me in the art of language design. I make no promises about the stability of your scripts or API interactions at the current stage of the project, because the status of the project is based off my personal quest for enjoyment.

My personal gesture regarding stability is that Scarlet will stay in the 0.x.x version scheme while it is unstable and prone to changes. Once 1.x.x arrives, I will focus on keeping API stable, so you can update without worrying about me breaking every script you have ever written. :)

Licensing

Scarlet started out as an educational project based on Crafting Interpreters and other compiler resources, which is why it is licensed as MIT. You can read the LICENSE file for more information, but the tl;dr is that you can use the code inside this repository as long as any significant chunks are accompanied by the license file.
