lupdate collecting strings from .lua files

[Kebap]

Hello!
I was looking for a lupdate-like tool to collect string data from source code, so they can be translated (in .ts files) for multi-language applications.
Does your code offer this functionality at all, or could you recommend other ways and tools to reach this goal?
We use Qt lupdate to fetch texts from c++ source as well, but now the lua code grows bigger, so we need to adjust.
Thanks in advance!
