You can use external lua modules, wrote with the Lua language
You should place it to the modules
folder
A module can be wrote in the single file. In this case module name will be same as filename
An example:
root
|
| modules
| conv.lua
local conv = require('conv')
The module can be placed in one folder with several files. In this case folder must have file init.lua with export code
An example:
root
|
| modules
| conv.lua
| money
| convert.lua
| compress.lua
| init.lua
local money = require('money')
