Overview

See {{Translate}} for how/when to use and more documentation.

p.translate

Translates a given key from Data:Dictionary. Manual invocation should only be used when additional parameters are required, such as {{Update layout}}, where the DISPLAYTITLE is generated using a translation key with expected parameters.

For normal usage, use the basic template.

Function parameters

• key – translation key (required).
• Language-specific:
  • lang_code_override (optional, named parameter) – language code overriding the automatic detection. See Data:LangCodes.json.
  • fallback_str (optional, named parameter) – value returned only if translation is missing. If set to empty string or nil, fallback will be empty (useful for detecting missing translations).

Examples

{{#invoke:Dictionary|translate|Update history}} Output: Update history

{{#invoke:Dictionary|translate|Updates|lang_code_override=pt-br}} Output: Atualizações

{{#invoke:Dictionary|translate|Update history|fallback_str=Custom fallback text.}} Output: Custom fallback text.
