BetterCommand

A translatable command API that implements brigadier command node.
The main propose of this project is support cross-platform like Bukkit, Velocity and Fabric.

Example source (Bukkit)

You can see this in CommandTest.java.

//Create command
var command = library.<CommandSourceStack, BetterCommandSource>module("mycommand", p -> {
