25 diff --untranslated-values-all en.yml is.yml
29 This utility prints the differences between two YAML files using
30 L<Test::Differences>. The purpose of it is to diff the files is
31 F<config/locales> to find out what keys need to be added to the
32 translated files when F<en.yml> changes.
40 Print this help message.
44 Show the hash keys that differ between the two files, useful merging
45 new entries from F<en.yml> to a local file.
47 =item --untranslated-values
49 Show keys whose values are either exactly the same between the two
50 files, or don't exist in the target file (the latter file
51 specified). The values are pruned according to global and language
52 specific blacklists found in the C<__DATA__> section of this script.
54 This helps to find untranslated values.
56 =item --untranslated-values-all
58 Like C<--untranslated-values> but ignores blacklists.
