nbt reader

-- 1) Wrap your Block Reader (here on the “back” of the computer)
local reader = peripheral.wrap("back")
if not reader or peripheral.getType("back") ~= "blockReader" then
  error("Block Reader not found on back")
end

-- 2) Grab the full chest NBT
local data = reader.getBlockData()
if not data or type(data.Items) ~= "table" then
  error("No chest data found")
end

-- 3) Helper to recursively dump a table
local function dump(t, indent)
  indent = indent or ""
  for k, v in pairs(t) do
    if type(v) == "table" then
      print(indent .. tostring(k) .. ":")
      dump(v, indent .. "  ")
    else
      print(indent .. tostring(k) .. " = " .. tostring(v))
    end
  end
end

-- 4) Iterate your slots
for _, item in ipairs(data.Items) do
  print(string.format("Slot %d - %s x%d", item.Slot, item.id, item.Count))

  -- 5) Dump full tag to inspect nutrition/expiration fields
  if item.tag then
    print("  Full NBT tag for this stack:")
    dump(item.tag, "    ")
  else
    print("  No tag data present on this item.")
  end

  -- 6) Once you know the path, you can extract directly:
  --[[
  local food = item.tag.FoodData
  if food then
    print("  Nutrition: " .. tostring(food.Nutrition))
    print("  Expiration (ticks): " .. tostring(food.Expiration))
  end
  ]]

  print("---")
