How to print string translation from object created by MO loader

[jasomdotnet]

Hi, I have been able to load translation.mo with MO loader. Now, how to print translation of string from object created by MO loader, something like:

echo $translations->gettext('Hello world!', 'optional-textdomain');

With my current knowledge I was not able to figure out from documentation. Is it possible?

You need install the gettext/translator package to use a translator in your templates. Once it's installed:

use Gettext\Translator;

$translator = Translator::createFromTranslations($yourMoTranslations);

echo $translator->gettext('Hello world');
echo $translator->dgettext('textdomain', 'Hello world');

[jasomdotnet]

So complete code after

composer require gettext/translator
composer require gettext/gettext

will looks like:

use Gettext\Loader\MoLoader;
use Gettext\Translator;

$loader = new MoLoader();
$translator = Translator::createFromTranslations( $loader->loadFile('languages/file.mo'));

echo $translator->gettext('Hello world');
echo $translator->dgettext('textdomain', 'Hello world');

Right? Do you think you can add this to the main readme file?

Can use __(); function in gettext v5?

Im trying to update version 4.6 to 5.5.1, in 4.6 i was using translations with the gettext extension

@lavitzz The translator functionality is in a different package: https://github.com/php-gettext/Translator

see my previous comments: https://github.com/php-gettext/Gettext/issues/240#issuecomment-559478396

Ok thx, i try: $translator = Translator::createFromTranslations( $loader->loadFile('languages/file.mo')); TranslatorFunctions::register($translator); and __() working perfect :)

@lavitzz can you share complete-example code?

[lavitzz]

@jasomdotnet yes, i use this:

public function __construct(
        MoLoader $moLoader,
        ContainerInterface $container
    ) {
        $this->moLoader = $moLoader;
        $this->langPath = $container->get('LANG_PATH');
        $this->languageRealURL = $container->get('LANGUAGE_REAL_URL');
    }
public function __invoke()
    {
        if (! empty($this->languageRealURL)) {
            $langFilePath = $this->langPath . $this->languageRealURL . '.mo';
            if (file_exists($langFilePath)) {
                $translator = Translator::createFromTranslations($this->moLoader->loadFile($langFilePath));
                TranslatorFunctions::register($translator);
            } else {
                throw new FileNotFoundException('File not found: ' . $langFilePath);
            }
        }
    }

I'm sharing my code so far:

use Gettext\Translator;
use Gettext\Loader\MoLoader;

$lang = 'sk' // set by a side function
define('ROOT', '/path/to/root');

function __( string $string, string $textdomain = null ) {

    static $t = null;

    global $basic_lang;

    $translation = ROOT . '/languages/' . $lang . '.mo';

    if (!file_exists( $translation )) {
        return $string;
    }

    if ($t === null) {

        $loader = new MoLoader();
        $t = Translator::createFromTranslations( $loader->loadFile( $translation ) );
    }

    //return $textdomain ? $t->dgettext( $textdomain, $string ) : $t->gettext( $string );
    return $t->gettext( $string );

}

//echo __( 'Buy a ticket', 'reservation' );
echo __( 'Buy a ticket' );
