vararg... just how many values are in there? oO

[Xubera]

is there a way i can determine the amount of variables passed through a vararg?

#... and #(...) seem to return the string length of the first value passed... ugh xD lol

Something like this should work.

local function foo(...)
    local args = {...}
    local numargs = #args
end

Wrapping a multiple value return in table brackets results in a keyless table containing the values. So if ... is (1,2,3,5,6,7), you end up with a table like such:

{
    [1] = 1,
    [2] = 2,
    [3] = 3,
    [4] = 5,
    [5] = 6,
    [6] = 7
}

...and numargs will be 6.

You can also get the number of variables by using select.

local therearethismanyvariables = select("#", ...)

Yep, either way should work fine. The table method works great if you're working with a dynamic number of params, while the select method is better if you just want to know if there are more than X number of params.

Whichever you find easier to code with, or fits better. I use the select method for parts of EventHorizon's frame activation, and the table method for a CLI framework that I've been toying with.
