NAME

       Zonemaster::Engine::Translator - translation support for Zonemaster

SYNOPSIS

           Zonemaster::Engine::Translator->initialize({ locale => 'sv_SE.UTF-8' });

           my $trans = Zonemaster::Engine::Translator->instance;
           say $trans->to_string($entry);

       This is a singleton class.

       The instance of this class requires exclusive control over $ENV{LC_MESSAGES} and the
       program's underlying LC_MESSAGES.  At times it resets gettext's textdomain.  On
       construction it unsets $ENV{LC_ALL} and from then on it must remain unset.

       On systems that support $ENV{LANGUAGE}, this variable overrides the locale() attribute
       unless the locale() attribute is set to "C".

ATTRIBUTES

       locale
           The locale used for localized messages.

               say $translator->locale();
               if ( !$translator->locale( 'sv_SE.UTF-8' ) ) {
                   say "failed to update locale";
               }

           The value of this attribute is mirrored in $ENV{LC_MESSAGES}.

           When writing to this attribute, a request is made to update the program's underlying
           LC_MESSAGES.  If this request fails, the attribute value remains unchanged and an
           empty list is returned.

           As a side effect when successfully updating this attribute gettext's textdomain is
           reset.

       data
           A reference to a hash with translation data. This is unlikely to be useful to end-
           users.

METHODS

       initialize(%args)
           Provide initial values for the single instance of this class.

               Zonemaster::Engine::Translator->initialize( locale => 'sv_SE.UTF-8' );

           This method must be called at most once and before the first call to instance().

       instance()
           Returns the single instance of this class.

               my $translator = Zonemaster::Engine::Translator->instance;

           If initialize() has not been called prior to the first call to instance(), it is the
           same as if initialize() had been called without arguments.

       new(%args)
           Use of this method is deprecated.

           See MooseX::Singleton-new|MooseX::Singleton/"Singleton->new">.

           locale
               If no initial value is provided to the constructor, one is determined by calling
               setlocale( LC_MESSAGES, "" ).

       to_string($entry)
           Takes a Zonemaster::Engine::Logger::Entry object as its argument and returns a
           translated string with the timestamp, level, message and arguments in the entry.

       translate_tag
           Takes a Zonemaster::Engine::Logger::Entry object as its argument and returns a
           translation of its tag and arguments.

       test_case_description
           Returns the translated test case description for a given test case ID.
