I was able to come up with steps leading to the desired state: 0. lock weblate repository 1. update libvirt.pot from the most recent potfile job 2. push to libvirt.git 2. wait for translations update from Fedora Weblate and merge it 3. pull from libvirt.git 4. apply the first 50 patches from this seires (with required changes to make sure all translation strings are updated) 5. update all po files with the attached script 6. update libvirt.pot by running meson compile libvirt-pot 7. apply patch 51 of this series 8. push to libvirt.git 9. wait for translations update from Fedora Weblate and merge it 10. unlock weblate repository The process takes about an hour if we're lucky as weblate is quite slow when processing such large amount of changes. The result can be seen at https://gitlab.com/jirkade/libvirt/-/commits/format-strings and the corresponding weblate repository at https://translate.fedoraproject.org/projects/libvirt/test/ I used d05ad0f15e737fa2327dd68870a485821505b58f commit as a base. If we agree this is a reasonable approach, I think we should apply it just after a release to give translators the whole release cycle to check or update the translations if they wish so. The attached script analyzes a single po file and updates all msgid strings to use permutable format strings. It also tries to update all translations, but only if the format strings in them exactly match (including their order) the corresponding msgid format string. That is, a msgstr will not be updated if format strings in it were incorrect or reordered or they already used the permutable form. That is, the processing should be a NO-OP except for strings that already used permutable format in msgstr, such translations were failing c-format check in weblate before but would be marked as correct now.
