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.

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($entry)

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

test_case_description($testcase)

Takes a string (test case ID) and returns the translated test case description.

BUILD

Internal method that's only mentioned here to placate Pod::Coverage.
