A simple Fabric Minecraft utility mod to check basic information about an ItemStack.
Usage
This mod is fully command driven. Use one of the following commands to check out the ItemStack's Identifier, ItemGroup and Material.
/what material/wm/info material
All commands will check the player's main hand and if that is empty, the offhand.
You can also specify an ItemStack (just like with the /give command) after all the newly
added Commands. If this command is not executed by a player, specifying the ItemStack is
mandatory.
