functions with until?

Not this:

until turtle.detectUp() == false then
	turtle.digUp()
	turtle.up()
else

But this:

repeat
	turtle.digUp()
	turtle.up()
until turtle.detectUp() == false

All you had to do was search Google for "Lua repeat": magic.

repeat

    turtle.up()
until turtle.detectUp() == false then
repeat
turtle.down()
until turtle.detectDown == true

repeat
    --Your code that will be repeated
until (condition that makes it stop)

local x = 1
repeat
    x = x + 1
    print(x)
until x == 10

The syntax for a repeat loop is this:

repeat
	--Your code that will be repeated
until (condition that makes it stop)

An exsample of this:

local x = 1
repeat
	x = x + 1
	print(x)
until x == 10

function mineup()
repeat
turtle.digUp
turtle.up
until turtle.detectUp() == false
repeat
turtle.down()
until turtle.detectDown() == true
end

So my code would be:

function mineup()
repeat
turtle.digUp
turtle.up
until turtle.detectUp() == false
repeat
turtle.down()
until turtle.detectDown() == true
end

function mineup()
repeat
turtle.digUp()
turtle.up()
until turtle.detectUp() == false
repeat
turtle.down()
until turtle.detectDown() == true
end

function mineup()
  repeat
	turtle.digUp()
	turtle.up()
  until turtle.detectUp() == false
  repeat
	 turtle.down()
  until turtle.detectDown() == true
end
