I think I’ll keep FTV in a separate repo for a few more weeks/months until it reaches a mature enough state. This will most likely happen after 6.0 is released, so the switch to the new Gramps version will probably happen in my repo. In the current “open beta” phase, I’m pushing new features/improvements/bugfixes several times a week. Once this slows down, I’ll consider opening a pull request for the addons-source. I expect the review of the PR to take some time (currently over 11000 lines in *.py files, including comments and empty lines).
As I understand this post, the content of the template.pot and the XX-local.po files just have to be appended to the merged files (addons.pot, XX.po). Maybe the script also needs to be updated.
I think @kmikkels would have mentioned if there was an obvious flaw in the process. I’ll change the workflow to keep the template.po so we can proceed and see what happens. I’ll post here when the file is available.
