33 This utility prints the differences between two YAML files using
34 L<Test::Differences>. The purpose of it is to diff the files is
35 F<config/locales> to find out what keys need to be added to the
36 translated files when F<en.yml> changes.
44 Print this help message.
48 Show the hash keys that differ between the two files, useful merging
49 new entries from F<en.yml> to a local file.
51 =item --untranslated-values
53 Show keys that B<exist in both the compared files> and whose values
54 are exactly the same. Use C<--keys> to a list of values that hasn't
57 The values are pruned according to global and language specific
58 blacklists found in the C<__DATA__> section of this script.
60 This helps to find untranslated values.
62 =item --untranslated-values-all
64 Like C<--untranslated-values> but ignores blacklists.
66 =item --validate-variables
68 Check that interpolated Ruby i18n variables (C<{{foo}}> and
69 C<[[foo]]>) are equivalent in the two provided files.
