To people who can actually use computercraft, I need your skill

• start small, write a program which prints the name of the first item in the chest.
• from there, get the stack count of that item, print this out too
• then add your logic, when the stack size is below a number, print a message "stack low"
• then make sure that what you are looking at is the item you are interested in, adjust your logic as needed
• change the stack low message so that it adds more of the low items
• add a check for if the item is not in the chest, display a message
• replace this message so that your program restocks the missing items

chest = peripheral.wrap("right")
slot = chest.getStackInSlot(9)

if slot = nil then
 redstone.setAnalogOutput("back",true)
 sleep(1,01)
 redstone.setAnalogOutput("back",false)
else
 print(slot.name.." is in slot "..i)
end

chest = peripheral.wrap("back") --# Change this to whatever

for i=1,chest.getInventorySize() do
    local slot = chest.getStackInSlot(i)
    --# Basicly what lupus59 said, you need your logic so it knows when to put more in the chest
    if slot then --# If something in the slot if you don't do this it will crash as slot.name won't exist
        --# Add if slot.name equals to food then
        --# And if the quantity is less than whatever emit a redstone signal?
        print("There are "..slot.qty.. " " ..slot.name.." in slot "..i)
    end
