OLoad.lua

OLoad.lua is a super simple function for creating function overloads. It's not the best in any regards, but it's there. Usage is as follows:

local overLoad = require("OLoad")

-- create an overloadable function:
local overLoadedFunction = overLoad(
	-- a function overload
	function(a,b,c)
		return "number","string","table"
	end,
	-- the arguments for the previous overload
	{"number","string","table"},
	-- repeat for every initial overload
)

-- add a version to an overloaded function:
overLoadedFunction:add(
	function(a,b,c)
		return "string", "table", "number"
	end,
	{"string","table","number"}
	-- 'add' can handle multiple functions, simply repeat this pattern for each.
)

-- add a default version to the overloaded function:
overLoadedFunction:add(
	function(...)
		local out = {}
		for i,v in ipairs({...}) do
			out[i] = type(v)
		end
		return unpack(out)
	end
)

-- execute an overloaded function:
print(
	overLoadedFunction(1,"str",{}) -- calls the correct version of the function for the given arg types
) -- prints "number	string	table"
