Player inventory callbacks

[Skulls]

For player inventories are there callbacks like the detached inventory on_take, on_put or do you need to parse from the receive fields? I'm trying to figure out a way to detect when an item was placed in a slot.

Looks like callbacks for the player inventory (non-detached or node) are

minetest.register_allow_player_inventory_action(function(player, action, inventory, inventory_info)
minetest.register_on_player_inventory_action(function(player, action, inventory, inventory_info))

As it says in the lua_api.txt a "move" action will have the item in the "from_list" when it is being checked for allowability, but the "to_list" when it is being placed. This small detail could cause several minutes (or hours... in my case) of frustration because the ItemStack seems to be fine when checked but then nil when placed.
