trying to figure out lua class loading

Had to change the LUA_PATH export to this

export LUA_PATH="./?/init.lua;./?.lua;/usr/local/share/lua/5.1/?.lua;/usr/local/share/lua/5.1/?/init.lua;/usr/local/lib/lua/5.1/?.lua;/usr/local/lib/lua/5.1/?/init.lua;/usr/share/lua/5.1/?.lua;/usr/share/lua/5.1/?/init.lua"

The part I added (the interesting bit) on the front looks like this

"./?/init.lua"

That says that when you run this type of code in lua

local HC = require("funk)

That you should look in the directory

./funk/init.lua

To load that module.

I was really doing this trying to figure out why/how to use hardoncollider in a love2d project. That projects looks to only come in a luarocks spec and everything I read indicated that using luarocks and love2d projects is not a good combination.

more stuff on loading once in init.lua

The other interesting thing is that in the file init.lua the variable

lua _NAME

Is set to the module (in my case funk), At that point you can be super selective about loading other modules and they will come from your directory.

require(_NAME .. ".class")

That require needs to be in the init.lua file. That will load another file from here on disk

./funk/class.lua

The point here is that you can control your names (you namespace) with this loading mechanism.

class

Lua out of the box at least for 5.1 does not have a traditional OO class builtin. You must provide it. I usually write this myself and I skip the parts that generally do not matter to me.

HardonCollider has more strict requirements in that area and wants to use something called class commons. See the next section.

common class loading?

Still not sure how any of this works ha.
