Coding

First, you have to make a loop so the machine keeps running:

while true do
 'Command
end

Now, inside of the loop, you have to add something to detect the block:

while true do
 if turtle.detect() then
 'Command
 end
end

After that, the block must be mined:

while true do
 if turtle.detect() then
  turtle.dig()
 end
end

This detects if a block is present, and then mines it. However, when all the 9 block spaces are filled with blocks (9*64=576 blocks), they must be dropped to collect new blocks:

while true do
 if turtle.detect() then
  turtle.dig()
 end
 itemcount = turtle.getItemCount(9)
 if itemcount == 64 then
 'Drop all stacks
 end
end

To drop all stacks, another loop must be added:

while true do
 if turtle.detect() then
  turtle.dig()
 end
 itemcount = turtle.getItemCount(9)
 if itemcount == 64 then
  for i=1,9 do
  'Select each stack and then drops it
  end
 end
end

To select each stack and drop it, a turtle.select() and a turtle.drop() must be added:

while true do
 if turtle.detect() then
  turtle.dig()
 end
 itemcount = turtle.getItemCount(9)
 if itemcount == 64 then
  for i=1,9 do
   turtle.select(i)
   turtle.drop()
  end
  turtle.select(1)
 end
end

Advanced Generator

This is the generator I created (for use with (height:4 width:2) monitor):

while true do
 if turtle.detect() then
  turtle.dig()
  term.clear()
  term.setCursorPos(1,1)
  a = turtle.getItemCount(1)
  b = turtle.getItemCount(2)
  c = turtle.getItemCount(3)
  d = turtle.getItemCount(4)
  e = turtle.getItemCount(5)
  f = turtle.getItemCount(6)
  g = turtle.getItemCount(7)
  h = turtle.getItemCount(8)
  i = turtle.getItemCount(9)
  print("Row 1: " .. a .. " (" .. math.floor(((a/(a+b+c+d+e+f+g+h+i))*100)) .. "%)")
  print("Row 2: " .. b .. " (" .. math.floor(((b/(a+b+c+d+e+f+g+h+i))*100)) .. "%)")
  print("Row 3: " .. c .. " (" .. math.floor(((c/(a+b+c+d+e+f+g+h+i))*100)) .. "%)")
  print("Row 4: " .. d .. " (" .. math.floor(((d/(a+b+c+d+e+f+g+h+i))*100)) .. "%)")
  print("Row 5: " .. e .. " (" .. math.floor(((e/(a+b+c+d+e+f+g+h+i))*100)) .. "%)")
  print("Row 6: " .. f .. " (" .. math.floor(((f/(a+b+c+d+e+f+g+h+i))*100)) .. "%)")
  print("Row 7: " .. g .. " (" .. math.floor(((g/(a+b+c+d+e+f+g+h+i))*100)) .. "%)")
  print("Row 8: " .. h .. " (" .. math.floor(((h/(a+b+c+d+e+f+g+h+i))*100)) .. "%)")
  print("Row 9: " .. i .. " (" .. math.floor(((i/(a+b+c+d+e+f+g+h+i))*100)) .. "%)")
  totalc = a+b+c+d+e+f+g+h+i
  print("Total: " .. totalc)
  print("-----------------")
  if a<10 then
  a = "0"..a
  end
  if b<10 then
  b = "0"..b
  end
  if c<10 then
  c = "0"..c
  end
  if d<10 then
  d = "0"..d
  end
  if e<10 then
  e = "0"..e
  end
  if f<10 then
  f = "0"..f
  end
  if g<10 then
  g = "0"..g
  end
  if h<10 then
  h = "0"..h
  end
  if i<10 then
  i = "0"..i
  end
  print(" ___ ___ ___ ")
  print("|" .. a .. " |" .. b .. " |" .. c .. " |")
  print("|___|___|___|")
  print("|" .. d .. " |" .. e .. " |" .. f .. " |")
  print("|---|---|---|")
  print("|" .. g .. " |" .. h .. " |" .. i .. " |")
  print("|___|___|___|")
  print(" ")
  print("-----------------")
  print("Cobble Farmer")
  print("By: NewFletcher")
 end
 totalcount = turtle.getItemCount(9)
 if totalcount == 64 then
  term.clear()
  term.setCursorPos(1,1)
  print("Dropping Stacks")
  print("...Please wait.")
  sleep(1)
  for i=1,9 do
   turtle.select(i)
   turtle.drop()
  end
  turtle.select(1)
 end
end
