How can a moduleScript get the script that required it?
So this is a generic question. So let's suppose we have an active moduleScript:
local module = {}
function module.f()
print("mekool")
end
return module
and a Script requires it:
require(game.ServerScriptService.ModuleScript)
Is there a variable that represents the script that required the module, so we could make something like:
local module = {}
local scriptthatrequiredthis = ?
function module.f()
print(scriptthatrequiredthis:GetFullName())
end
return module
(Since of course the keyword script redirects to the module itself)
Anyways, thank you, your help is very appreciated!

No, ModuleScripts have no in-built variables or information. This can be accomplished through two other ways.
Method 1: Parameters
You can call functions in ModuleScripts and give them parameters. From this, we can simply just use the parameter;
ModuleScript
local module = {}
function module.f(requirer)
print(requirer:GetFullName())
end
return module
Requirer
local module = require(game.ServerScriptService.ModuleScript) module.f(script)
Method 2: Setup
An alternate, and slightly more advanced method is to perform a setup of sorts, using a function in the ModuleScript. This method may cause errors, especially in terms of nil values, if the proper precautions are not performed.
ModuleScript
local module = {}
local requirer
function module.setup(scriptThatRequired)
requirer = scriptThatRequired
end
-- Putting a repeat/while loop here would stop the code, including the script that required it, so therefore it would never get to the setup point
function module.f()
if not requirer then -- If the script has not been setup when the function is called
repeat wait() until requirer
end
print(requirer:GetFullName())
end
return module
Requirer
local module = require(game.ServerScriptService.ModuleScript) module.setup(script) module.f()
Hope I helped!
