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