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 whose values are either exactly the same between the two
|
|
files, or don't exist in the target file (the latter file
|
|
specified). 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.
