How to access library from folder when loaded in stand-alone interpreter

[christian govella <christian.govella@...>]

Hi,

Lua stand-alone interpreter can be given option -l to require a library into the workspace. The interpreter help says

-l name  require library 'name' into global 'name'

I was trying to load a library lib from a folder named test, so

$ lua -l test.lib

I also tried,

$ lua -l test/lib

But then, how to access the loaded library in the interpreter?

I suppose both dot (.) and slash (/) are not valid characters in a variable name, e.g.

> test.lib.myfun()

stdin:1: attempt to index a nil value (global 'test')
stack traceback:
stdin:1: in main chunk
[C]: in ?

I figured I could use the global _G variable,

> _G['test.lib'].myfun()
42

But is there no more elegant way to do this? Would it not have been good if the directory name was not included in the variable name? Any idea?

I looked in PIL book chapter I.1 The stand-Alone Interpreter but could not find any answer. Using Lua 5.4.3.

Thanks,
