Kursive
A Minecraft mod that allows you to run kotlin scripts on the client and the server on the fly!
Quick answer
Which Kursive release should I use?
Kursive 0.4.0-alpha.3+26.3 targets 26.3 with Fabric. Installation on the client is optional. Installation on the dedicated server is optional. All 2 required mods have matching files.
Where it goes
Is Kursive required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does Kursive 0.4.0-alpha.3+26.3 need?
0.4.0-alpha.3+26.3. Change the file and its required mods may change too.
Install Fabric Language Kotlin, Fabric API first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Kursive add?
Kursive
A Minecraft mod that allows you to run kotlin scripts on the client and the server on the fly!
About the Project
The idea of allowing scripts to be run on the Minecraft client originated when
EssentialClient was first being
implemented. My scripting implementation achieved my goal, but it was poorly designed
and due to running on my own interpreted language had severe performance limitations.
After discovering kotlin scripting I decided that it would be an ideal language to
use for a scripting mod. It can compile directly into bytecode to run on the JVM
as well as not requiring wrapper APIs allowing scripts to interface directly with
Minecraft's code.

Documentation
The mod's documentation can be found here.
The documentation details how to start developing your first scripts as well as
detailing how to run scripts on the client and server.
