Qute: Template attributes in template extensions

[andlinger]

I would like to implement a template extension method to properly format a MonetaryAmount parameter. Here it would be great if I could use the locale attribute of the TemplateInstance, which I already use for the MessageBundles anyway.

It would be great if you could inject the specific value via an annotation.

@TemplateExtension
public class TemplateExtensions {

    public static String formatMoney(MonetaryAmount price, @TemplateAttribute("locale") Locale locale) {
        var formatter = MonetaryFormats.getAmountFormat(AmountFormatQuery.of(locale));
        return formatter.format(price);
    }
}
