Recursive Require

[yetneverdone]

What error does it throw?

It's a compiler error. Basically in lua you cant do that I suppose

I can't really test it myself right now as I don't have Lua or Love installed on my work computer, but I put the following code in an online compiler:

Code: Select all

local filename = "math.lua"
local tree = {}
tree[filename:gsub(".lua","")] = require(filename:gsub(".lua",""))
print(tree["math"].min(10, 100))

And it compiles and runs fine for me o.o

Compiler I used

Oh, i didn't notice that you're indexing in the tree. That works i think, im going to check it later

Let me know if it works!

Hey, I was just now looking for a way to do a recursove require, and for love2d as well Before I saw this thread I came up with this function, I'm a pretty big noob at Lua so it's probably totally wrong LOL, but oh well at least I tried Basically it is supposed to take the name of your directory where your libraries are, the library directory itself, and a table with the names of the modules you want (in case you don't want all the modules) and it is supposed to return a table with the acquired modules. Here is what I have so far

Code: Select all

function recuire(libsDir, libName, requiredModules)
--create table to store the modules
    local modules = {}
    local currentModule = 1
--fill module table with required modules and return it
    for currentModule, #requiredModules, 1 do
        modules[requiredModules[currentModule]] = require "./"..libsDir..libName.."/"..requiredModules[currentModule]
    end
    return modules
end

Since require doesn't need you to put the .lua at the end of your module file names I don't think I really need to use gsub in this case. BUT I'm not sure if require can use file paths like how I use it here, so if it can't then, well idk hehe, I'll just have to git gud enough to figure it out

If you don't mind the module being a global variable, you can use the built-in global table to assign it a value and use it conveniently:

Code: Select all

_G[MODULE_NAME] = require("flux.lua")

MODULE_NAME.to(...) -- this will work
