Language files for modules

When you install a new modul, language file for english is ok, but what do we do with other languages?
It looks wierd to have something lime _CHAT_TOP_MENU_ITEM?

You need to create a new language file for the module.

modules/vendor_name/module_name/install/langs

Make a copy of the en.php file.

Rename to your language. ru.php for russian for example.

Then edit the file. Change the english text to your language.

Then go into admin->tools->modules select the module and recompile the language.

I did that and all that happens is that my language file is rewritten with english and string still looks wierd.

Ok, string is gone but still the whole language file is overwritten with English

Your leaving the copies in the modules/vendor_name/module_name/install/langs folder correct?

Your not moving them to the langs folder in the root of the site are you?

I have never seen those module language folders get over written. I does not make sense to me as dolphin does not write to those folders so i have no idea why that is happening.

I know it's strange. I didn't move them from theri folder.  Luckily it was just 20 lines at the bottom and I added them manually in non-english language file.
