Checking if a table/saved var is empty.

[Grimsin]

Is there a way to check if a table or variable is empty? lets say your saved var table has{
["bars"] = {
{
{
["arcLength"] = 360,
["prowl"] = false,
["spellGlow"] = true
}
}
}
}

and i want to check to see if bars is currently an empty table or not.

how would you do that? I tried doing if blahblahvar.bars ~= {} but that only checks to see if its a table or not i want it to check to see if its an empty table.

if not next(table) then
     -- table is empty
else
     -- table is not empty
end

function empty(t)
  return next(t) == nil; -- next(t) returns the "first" key in t
end

That will actually only check that “blahblahvar.bars” is not the same table as “{}”... and since you just created that table for your comparison, of course it’s not the same one.

If you wanted to see if “blahblahvar.bars” was a table, you’d do it like this:

if type( blabhblahvar.bars ) == "table" then ...

What i needed was the next part the end result was this

if MacaroonSavedState.bars then
if next(MacaroonSavedState.bars) ~= nil then return end
end
