=head1 NAME
locale-diff - Compare two YAML files and print how their datastructures differ
=head1 SYNOPSIS
# --keys is the default
diff en.yml is.yml
diff --keys en.yml is.yml
# --untranslated-values compares prints keys whose values don't differ
diff --untranslated-values en.yml is.yml
# --untranslated-values-all compares prints keys whose values
# don't differ. Ignoring the blacklist which prunes things
# unlikley to be translated
diff --untranslated-values-all en.yml is.yml
# Check that interpolated variables ({{var}} and [[var]]) are the same
diff --validate-variables en.yml is.yml
=head1 DESCRIPTION
This utility prints the differences between two YAML files using
L<Test::Differences>. The purpose of it is to diff the files is
F<config/locales> to find out what keys need to be added to the
translated files when F<en.yml> changes.
=head1 OPTIONS
=over
=item -h, --help
Print this help message.
=item --keys
Show the hash keys that differ between the two files, useful merging
new entries from F<en.yml> to a local file.
=item --untranslated-values
Show keys that B<exist in both the compared files> and whose values
are exactly the same. Use C<--keys> to a list of values that hasn't
been merged.
The values are pruned according to global and language specific
blacklists found in the C<__DATA__> section of this script.
This helps to find untranslated values.
=item --untranslated-values-all
Like C<--untranslated-values> but ignores blacklists.
=item --validate-variables
Check that interpolated Ruby i18n variables (C<{{foo}}> and
C<[[foo]]>) are equivalent in the two provided files.
=item --dump-flat
Dump a flat version of the translation hash in YAML format,
i.e. "foo.bar" instead of "{foo}->{bar}".
