[Enigma-devel] Please upgrade to Lua 5

[Roland Illig]

Hi,

I would like Lua to be upgraded to version 5 because it allows nicer 
function closures. The attached example does not work with Lua 4, but 
with Lua 5.

If you don't have the time for this upgrade I may help you.

-- uncomment for Lua 4
-- true = (0 == 0)
-- false = not true

onoff = {}
onoff[false] = "off"
onoff[true] = "on"

switches = {}
for y = 0, 4 do
  switches[y] = {}
  for x = 0, 4 do
    switches[y][x] = false
  end -- for
end -- for

function toggle(on, x, y)
  switches[y][x] = on
  print("switch ("..x..","..y..") toggled "..onoff[on]..".")
end -- function

function make_toggle(x, y)
  return function(on)
    return toggle(on, x, y)
  end -- function
end -- function

toggle12 = function(on) toggle(on, 1, 2) end

toggle12(true)
toggle12(false)
