How can optionsDb.lua know which module is loaded?

[uboats]

For each module X, there is ...\aircraft\X\Options\optionsDb.lua

 

In X\entry.lua, we can use current_mod_path to know which module is loaded.

 

However, current_mod_path is not available in optionsDb.lua.

 

I want to add something in optionsDb.lua and needs to know the corresponding module (or the path of that module or the path of this optionsDb.lua). Is there any way to achieve it? Something automatic way like current_mod_path, instead of manually write down the path.
