[ 151 ] Chapter 5 If, for some reason, we needed to do a multi-line string, and the syntax is something like this: msgid "" "Original string" "More text..." msgstr "" "New string" "More text..." We should note that the first string is always empty ("") on a multi-line translation. Now let's take a look at a configuration for a string translated by Drupal. formatPlural(): #: day.js:0 msgid "is 1 day" msgid_plural " @count days" msgstr[0] "1 día" msgstr[1] "@count días" Again, the extractor found existing values for us, and the translation is already complete. But the format is a little different than other entries. The msgid line always points to the first string in the Drupal.formatPlural() call. The code that generated the previous configuration was Drupal.formatPlural(i, "1 day", "@count days"). That first string, 1 day, became the message ID. Beneath that is the original plural form: msgid_plural " @count days" Note that in this case, we use msgid_plural instead of just msgid. The last two lines are the Spanish translations of these two strings: msgstr[0] "1 día" msgstr[1] "@count días" Just as with .info files, an array-like syntax is used here. The first item, msgstr[0], is the singular form. The second item is the plural form. And that's all there is to handling the plural format translations. Once we've translated all the strings, we are done with the translation file. Next, we just need to put it in the right place.

Lost in Translations What if a term should remain untranslated? Some of the terms that the extractor finds may be terms you don't want to translate. To leave these terms untranslated, just set the msgstr to be an empty string: msgstr "". To make the translation file available to Drupal's translation system, you should simply put the translation file in the translations/ directory of your theme (or module). For us, the file is placed in sites/all/themes/frobnitz/translations/. From there, Drupal takes over and we're done. While developing a translation, you may have to manually reload your translation in order to coerce Drupal into re-parsing the translation files. See the next section for details. Running the code with the Spanish translation will show text that looks like this: Hoy es Jueves. Quedan 2 dias til Sábado. How is this working? Drupal has taken our translation file and built a new JavaScript file (located in sites/default/files/languages/). When the page loads and Spanish is the selected language, Drupal adds a link to that extra JavaScript file: The highlighted section shows the inclusion of the translation JavaScript that Drupal created for us. The contents of that file look like this: Drupal.locale = { 'pluralFormula': function($n) { return Number(($n!=1)); }, 'strings': { [ 152 ] This material is copyright and is licensed for the sole use by Richard Ostheimer on 18th June 2009 2205 hilda ave., , missoula, , 59801
