Onioning API
Onioning API is a NeoForge library for building nested command scripts that extend standard Minecraft commands, covering version 1.21.1 only.
What it does
A script in Onioning API can nest functions inside one another using onion-skin syntax, so a single expression layers several commands together. Developers, mapmakers and server administrators can use it to automate tasks and to deploy standalone RPG spells, while the library caches persistent coordinates on disk. The client and the server both need the mod, and its latest NeoForge build is 1.0.4-beta for 1.21.1 on the beta channel. The code is under the MIT License and is not open source.
Key features
Nested onion-skin syntax
Expressions can be layered inside one another, letting a script combine several commands in a single line.
Persistent coordinate cache
Positions are stored on disk and reused later, so scripts can refer to places across sessions.
Item NBT bindings
Packed expressions can be bound to item data, so an item can carry and run its own script or spell.
