module Module can't be found but file exists at location?

[LamboCreeper 0]

Hey,

I haven't worked with Lua in a while and recently my friends and I started a new modded game. I'm currently trying to require another file from another, and to my knowledge have done it to how the syntax describes. However, OpenOS is giving me an error stating the following:

However, when running the cd command it states that core.lua does indeed exist in the directory /home/

This is my code:

-- core.lua

function catch(inp)
	return inp[1]
end

function try(inp)
	status, res = pcall(inp[1])
	if not status then
		inp[2](res)
	end
	return res
end

-- test.lua

function dir()
   local str = debug.getinfo(2, "S").source:sub(2)
   return str:match("(.*/)")
end

-- this is where it breaks:
require(dir() .. "core.lua")

local http

core.try {	
	function()
		http = require("socket.http")
		local body, code = http.request('https://raw.githubusercontent.com/rxi/json.lua/master/json.lua')
		local f = assert(io.open('modules/json.lua', 'wb'))
		f:write(body)
		f:close()
		print('Successfully downloaded json.lua module.')
	end, core.catch {
		function(err)
			print('Caught Error: ' .. err)
		end
	}
}

If someone could please explain to me what I am doing wrong and more specifically how to fix the issue it would be greatly appreciated.

The 'require' function is for modules in your package path. 'load' and 'dofile' are for actual file paths.

Require computes paths by converting periods to slashes. Instead use "/home/core"

 

From what the error spat out it may still not work, but adding .lua certainly isn't helping.
