Translation Generation

PREREQUISITES

Make sure you've completed the datagen setup process first.

Setup

First, we'll make our provider. Remember, providers are what actually generate data for us. Create a class that extends FabricLanguageProvider and fill out the base methods:

public class FabricDocsReferenceEnglishLangProvider extends FabricLanguageProvider {
	protected FabricDocsReferenceEnglishLangProvider(FabricDataOutput dataOutput, CompletableFuture<RegistryWrapper.WrapperLookup> registryLookup) {
		// Specifying en_us is optional, as it's the default language code
		super(dataOutput, "en_us", registryLookup);
	}

	@Override
	public void generateTranslations(RegistryWrapper.WrapperLookup wrapperLookup, TranslationBuilder translationBuilder) {
	}
}

NOTE

You will need a different provider for each langauge you want to generate (eg. one ExampleEnglishLangProvider and one ExamplePirateLangProvider).

To finish setup, add this provider to your DataGeneratorEntrypoint within the onInitializeDataGenerator method.

pack.addProvider(FabricDocsReferenceEnglishLangProvider::new);

Creating Translations

Along with creating raw translations, translations from Identifiers, and copying them from an already existing file (by passing a Path), there are helper methods for translating items, blocks, tags, stats, entities, status effects, item groups, entity attributes, and enchantments. Simply call add on the translationBuilder with what you want to translate and what it should translate to:

translationBuilder.add("text.fabric_docs_reference.greeting", "Hello there!");

Using Translations

Generated translations take the place of a lot of translations added in other tutorials, but you can also use them anywhere you use a Text object. In our example, if we wanted to allow resource packs to translate our greeting, we use Text.translatable instead of Text.of:

ChatHud chatHud = MinecraftClient.getInstance().inGameHud.getChatHud();
chatHud.addMessage(Text.literal("Hello there!")); 
chatHud.addMessage(Text.translatable("text.fabric_docs_reference.greeting"));
