Reuse the core translator is possible to generate translations

I'll add that the current way using regex might not be the easiest/safest.
I would try to simply boot the module and get all the translations needed with the prestashop built-in translation system that must be aware of all needed translations.

Plus i think it's @matks that told me about some kind of already built-in translation system in prestashop capable of generating needed translation keys for a module/theme (or something like that).
So now that we have a translation module working, i think it's important that the next step is to get informations about what exists and how we can use it for our needs.

Answer from @matks

So, I know that:

prestashop can translate native modules using one system A
prestashop can translate 3rd party modules (such as this one) using one system B

And system A and system B are not the same (dont asky me why roll_eyes).

Also, we have enabled a system C that uses Symfony translator to be able to translate Symfony modules, and legacy modules (= modules not using Symfony) can use it too ! This one is fully documented here: https://devdocs.prestashop.com/1.7/modules/creation/module-translation/new-system/ and is backward compatible: if a module was using system B and is switching to system C, translations already created for system B can be used by system C.

However this system C is available since PS 1.7.6
