* @defgroup plugin_translatable Annotation for translatable text | |
* @{ | |
* Describes how to put translatable UI text into annotations. | |
* | |
* When providing plugin annotation, properties whose values are displayed in | |
* the user interface should be made translatable. Much the same as how user | |
* interface text elsewhere is wrapped in t() to make it translatable, in plugin | |
* annotation, wrap translatable strings in the @ Translation() annotation. | |
* For example: | |
* @code | |
* title = @ Translation("Title of the plugin"), | |
* @endcode | |
* Remove spaces after @ in your actual plugin - these are put into this sample | |
* code so that it is not recognized as annotation. | |
* | |
* To provide replacement values for placeholders, use the "arguments" array: | |
* @code | |
* title = @ Translation("Bundle !title", arguments = {"!title" = "Foo"}), | |
* @endcode | |
* | |
* It is also possible to provide a context with the text, similar to t(): | |
* @code | |
* title = @ Translation("Bundle", context = "Validation"), | |
* @endcode | |
* Other t() arguments like language code are not valid to pass in. Only | |
* context is supported. | |
* | |
* @see i18n | |
* @see annotation | |
* @} | |
