self anvil

So I am pretty sure you have that moment when you go on a mining trip and your iron pickaxe just almost breaks and you wish you had an anvil but you don't so you are stuck in a cave with no iron pickaxe but with this data pack when you open your crafting table put the tool you want to repair and the ore that it is made of with it in the crafting table and you can have it fully repaired it works with other tools but some exceptions
1. wooden tools like.... why would you need to repair them
2. netherite tools... who would go mining for netherite and just use 1 up for your tools?
3. hoes so... they are useless and break slowly unless you want to get the serious dedication achievement I don't think repairing hoes will be useful.
