How do I iterate a simple Lua table, that is a sequence, from end?
Example of wanted behavior:
local mytable = {'a', 'b', 'c'}
for i, value in reversedipairs(mytable) do
print(i .. ": " .. value)
end
should output
3: c
2: b
1: a
How to implement here reversedipairs
?
Thank you, @Piglet, for useful link.
local function reversedipairsiter(t, i)
i = i - 1
if i ~= 0 then
return i, t[i]
end
end
function reversedipairs(t)
return reversedipairsiter, t, #t + 1
end
Actually, I figured out an easier way may be to
local mytable = {'a', 'b', 'c'}
for i = #mytable, 1, -1 do
value = mytable[i]
print(i .. ": " .. value)
end
