MantleJS
by Pelemenguin
MantleJS lets Mantle books be written and extended through KubeJS scripts on Forge 1.20.1, for both client and server.
What it does
A KubeJS addon for Mantle, the library behind several Forge mods. Scripts can define custom Mantle books, so a modpack author can add a book without writing Java. The project lists Architectury API, KubeJS, Mantle and Rhino as required dependencies, and it runs on client and server. Released under the MIT License, it is open source, and Forge files exist for 1.20.1 only.
Key features
Custom Mantle books
Scripts create new Mantle book entries, with their own pages and contents, for use in the game.
KubeJS scripting
Book definitions are written as KubeJS scripts, so changes apply without compiling a Java mod.
Example book script
The project includes an example that shows how to create a Mantle book through KubeJS.
