Ben bazen hata bastırılması ile ilgisi var olduğunu biliyorum ama Drupal kod bakıyorum ve ben sözdizimi tanımıyor:

Örnek 1:

$batch = array(
'operations' => $operations,
'finished' => '_install_profile_batch_finished',
'title' => st('Installing @drupal', array('@drupal' => drupal_install_profile_name())),
'error_message' => st('The installation has encountered an error.'),
);

Örnek 2:

drupal_set_title(st('@drupal installation complete', array('@drupal' => drupal_install_profile_name())));

Örnek 3:

$output .= '<p>'. (isset($messages['error']) ? st('Please review the messages above before continuing on to <a href="@url">your new site</a>.', array('@url' => url(''))) : st('You may now visit <a href="@url">your new site</a>.', array('@url' => url('')))) .'</p>';
