Chris@0 9 * @defgroup plugin_translatable Annotation for translatable text
Chris@0 10 * @{
Chris@0 11 * Describes how to put translatable UI text into annotations.
Chris@0 12 *
Chris@0 13 * When providing plugin annotation, properties whose values are displayed in
Chris@0 14 * the user interface should be made translatable. Much the same as how user
Chris@0 15 * interface text elsewhere is wrapped in t() to make it translatable, in plugin
Chris@0 16 * annotation, wrap translatable strings in the @ Translation() annotation.
Chris@0 17 * For example:
Chris@0 18 * @code
Chris@0 19 * title = @ Translation("Title of the plugin"),
Chris@0 20 * @endcode
Chris@0 21 * Remove spaces after @ in your actual plugin - these are put into this sample
Chris@0 22 * code so that it is not recognized as annotation.
Chris@0 23 *
Chris@0 24 * To provide replacement values for placeholders, use the "arguments" array:
Chris@0 25 * @code
Chris@0 26 * title = @ Translation("Bundle !title", arguments = {"!title" = "Foo"}),
Chris@0 27 * @endcode
Chris@0 28 *
Chris@0 29 * It is also possible to provide a context with the text, similar to t():
Chris@0 30 * @code
Chris@0 31 * title = @ Translation("Bundle", context = "Validation"),
Chris@0 32 * @endcode
Chris@0 33 * Other t() arguments like language code are not valid to pass in. Only
Chris@0 34 * context is supported.
