Module:Navpills

local mArguments --initialize lazily local p = {}

-- Returns a table containing the numbers of the arguments that exist -- for the specified prefix. For example, if the prefix was 'data', and -- 'data1', 'data2', and 'data5' exist, it would return {1, 2, 5}. local function getArgNums(prefix, args) local nums = {} for k, v in pairs(args) do local num = tostring(k):match('^' .. prefix .. '([1-9]%d*)$') if num then table.insert(nums, tonumber(num)) end end table.sort(nums) return nums end
