Library not loading?

[superbacon 0]

I've been working on this library to automatically change decimal to hexadecimal, but i've been running into a few problems. The first one being that for some reason when i try to load the library, it returns;

home/test; 1; module 'hex' not found

    no field package.preload['hex']

    no field package.delayed['hex']

/lib/hex.lua; 3; <name> expected near '='

Here's the code:

hex = {}

local function = hex.toHex(input)
	local a = input/16
	local b = a/16
	local c = b/16
	local d = c/16
	local e = d/16
	local g = input%16
	local h = a%16
	local i = b%16
	local j = c%16
	local k = d%16
	local l = e%16
	if g,h,i,j,k,l < 9 then
		if g = 10 then
			g = "a"
		end
		if g = 11 then
			g = "b"
		end
		if g = 12 then
			g = "c"
		end
		if g = 13 then
			g = "d"
		end
		if g = 14 then
			g = "e"
		end
		if g = 15 then
			g = "f"
		end
		if h = 10 then
			h = "a"
		end
		if h = 11 then
			h = "b"
		end
		if h = 12 then
			h = "c"
		end
		if h = 13 then
			h = "d"
		end
		if h = 14 then
			h = "e"
		end
		if h = 15 then
			h = "f"
		end
		if i = 10 then
			i = "a"
		end
		if i = 11 then
			i = "b"
		end
		if i = 12 then
			i = "c"
		end
		if i = 13 then
			i = "d"
		end
		if i = 14 then
			i = "e"
		end
		if i = 15 then
			i = "f"
		end
		if j = 10 then
			j = "a"
		end
		if j = 11 then
			j = "b"
		end
		if j = 12 then
			j = "c"
		end
		if j = 13 then
			j = "d"
		end
		if j = 14 then
			j = "e"
		end
		if j = 15 then
			j = "f"
		end
		if k = 10 then
			k = "a"
		end
		if k = 11 then
			k = "b"
		end
		if k = 12 then
			k = "c"
		end
		if k = 13 then
			k = "d"
		end
		if k = 14 then
			k = "e"
		end
		if k = 15 then
			k = "f"
		end
		if l = 10 then
			l = "a"
		end
		if l = 11 then
			l = "b"
		end
		if l = 12 then
			l = "c"
		end
		if l = 13 then
			l = "d"
		end
		if l = 14 then
			l = "e"
		end
		if l = 15 then
			l = "f"
		end
		local hexnum = tonumber(l..k..j..i..h..g)
		return hexnum
	end
	return hex

Sorry it's so long!

First, replace local function = hex.toHex(input) to function hex.toHex(input).

Second, you can't use = in if condition. If you want to check for equality, use ==.

Third, you must end the function with the end operator.

Fourth, the return hex line is incorrect. You didn't define the hex variable so the line will make the function return nil.

Fifth, you can't do if a,b,c < 42 then. You must check every variable and then "sum" the answer using and, or, not. E.g., a < 42 and b < 42 and c < 42 checks that a, b, c all less than 42.

Sixth, this is the most inefficient dec-to-hex algorithm I've seen so far. The whole function can be replaced with this:

function hex.toHex(num)
  return ("%x"):format(num)
end

How are you trying to load the library?
