scripts/i18n: add command 'normalize-po-files' The translation files in the Kallithea repository contained references to the location(s) of each string in the repository. This is useful to translators, but is not needed for all other users. The big problem with that information is that it changes very commonly as a result of normal development in Kallithea, causing a lot of unimportant delta in the Kallithea repository, thus causing unnecessary repository growth. In this commit, a basic version of the script is added, only containing the code to normalize the translation files by removing generated and outdated data. This can be used to check or ensure internal consistency between code and translations, by extracting and merging and then removing most of it again with normalize-po-files: ./setup.py extract_messages for po in kallithea/i18n/*/LC_MESSAGES/kallithea.po; do msgmerge --width=76 --backup=none --previous --update $po kallithea/i18n/kallithea.pot ; done scripts/i18n normalize-po-files kallithea/i18n/kallithea.pot kallithea/i18n/*/LC_MESSAGES/kallithea.po Includes contributions from Mads Kiilerich.
