Intake 
Intake is a command parsing library that can be implemented along various platforms, such as Minecraft.
When a user inputs a command:
/sum 1 2
You can easily handle that request with only a couple lines of code.
public class Commands {
@Command(
aliases = "sum",
desc = "Adds two numbers and returns their result",
perms = "math.sum",
usage = "[number] [number]"
)
public void sum(CommandSender user, int a, int b) {
user.sendMessage(a + b);
}
}Intake allows you to define custom providers for your own classes and handle errors with ease. Check out the detailed breakdown of the project for more details.
Example
To see how easy it is to implement Intake, take a look at the Bukkit module. For game developers that want to extend that module specifically, all you need to do is add this to your JavaPlugin class:
@Override
public void onLoad() {
BasicBukkitCommandGraph cmdGraph = new BasicBukkitCommandGraph();
cmdGraph.getRootDispatcherNode().registerCommands(new Commands());
new BukkitIntake(this, cmdGraph).register();
}An example Bukkit plugin is provided for your convenience here.
