Is it possible to scan all the options in a module?

Is it possible for a server script to scan all the options in a module script? What I mean is instead of having like 30 if statements, Could you just get all the options in a module and look for the value im looking for?

I’m not entirely certain what you mean by options in a module script.

Maybe you’re looking for a dictionary?

#3 
local module = {
	exaple = "Example";
	exaple2 = "Example2";
}

return module

The options are example1 - 2, Sorry for the confusion, I want to know how a script could look though all the “options” and if they find them they return true

You could do just module[lookingFor] which is a truthy value if lookingFor exists… well, unless the value is false, but you can do a ~= nil if you only want to know it exists.

Say the value is a string, How could you check that? Please can you send a quick sample script thx

if(module[“potato”]) then
    print(“potato was found and not false”)
end

if(module[“potato”]~=nil) then
    print(“potato exists”)
end

Oh, That isn’t what I meant, Ill re-explain myself, Sorry:

Basically, I have a localscript that sends data to the server (from a textbox) And if that text from the textbox matches with one of the strings in the module, Then it allows access, I dont want to do an if statement for every single key, My question was how you can scan through all the different keys in a module to see if one matches, Sorry for the confusion.

My understanding of your question is that you want to check if a value is in a dictionary, so the easiest way would be to use a for loop.

local function scanTable(tab)
	for k, v in pairs(tab) do
		if v == optionToFind then
			return true
		end
	end
	
	return false
end

An alternative is to structure your ModuleScript like this, with the options being the keys:

local module = {
	["Option1"] = true,
	["Option2"] = true,
}

This way, you don’t have to use a for loop and you can just check module[option], which will return true if the option exists.

Can you make the string you are searching for the key of the dictionary? That’s generally how I try to structure these. That way you can just do like module[text] = true to set it and module[text] = nil to unset it. Then you can just do module[text] to check if it exists. This will only work if the keys you already make don’t hold to much significance though.
