Think about that in the other direction.
You have a your git clone of XOOPS-monxoops-Traduction-FR.
You also have your wamp accessible XoopsCore25.
Make a script (*.bat file) that will copy the htdoc directory from XOOPS-monxoops-Traduction-FR to the htdoc directory in XoopsCore25 (i.e. using robocopy). Add another line in the script to copy the upgrade directory, too. (You want to make sure you don't copy the ".git" folder as that would be bad.)
Now, adjust your workflow to edit your translation in your XOOPS-monxoops-Traduction-FR repository, then run the copy script to test everything in wamp.
If you automate this with a script, and always edit in the XOOPS-monxoops-Traduction-FR repository clone, you always have all the updates that need commited in the right place.
A couple of apologies:
Sorry that the language folders are so awkward to work with. Making the translations much easier to work with and install is a high priority in the next generation XoopsCore.
Also sorry to be vauge about the Windows commands -- last time I rebooted into Windows, I had to wait more that two hours for updates and I don't have that much time right now.
