Localization of Qute templates with lots of static text

[cdhermann]

I'm developing a Qute template with lots of static, HTML formatted text and very little of dynamic parts. For the static text I use the MessageBundle feature. For a lot of static text, this isn't quite convenient. Are there localization solutions adressing the following problems?

1. Different template for languages. E.g. template.de-AT.html. For Austrian German, automatically this template is selected
2. Different languages do number formatting differently. Is it possible to retrieve the Locale object inside a qute template which is actually used by Qute when rendering the document to be able to use `{str:fmt(locale,'%tA',now)} or decide on time and date formatting?
3. When using @CheckedTemplate and Templates.TemplateName().renderAsync() how do I specify a different locale than the one defined in the property quarkus.default-locale?

I agree that message bundles are not a good match for this use case.

1. Different template for languages. E.g. `template.de-AT.html`. For Austrian German, automatically this template is selected

This is not supported yet.

2. Different languages do number formatting differently. Is it possible to retrieve the Locale object inside a qute template which is actually used by Qute when rendering the document to be able to use `{str:fmt(locale,'%tA',now)} or decide on time and date formatting?

Not out of the box but you can use an extension method like this:

@TemplateExtension(namespace = "attr")
static String locale(@TemplateAttribute("locale") Object locale) {
   return locale;
}

and then use {str:fmt(attr:locale,'%tA',now)} in the template.

I've just created #25785.

3. When using `@CheckedTemplate` and `Templates.TemplateName().renderAsync()` how do I specify a different locale than the one defined in the property `quarkus.default-locale`?

You can set the locale attribute of a template instance as described in the docs, i.e. something like Templates.TemplateName().setAttribute("locale", Locale.GERMAN).renderAsync(). When using Qute together with RESTEeasy then the locale attribute is derived from the the Accept-Language header if not set manually.

Thanks a lot for your exhaustive answer. Now, I think I also understand https://quarkus.io/guides/qute-reference#localization. This means when using quarkus-resteasy-qute Qute doesn't do any auto formatting with respect to the locale. It just sets the locale attribute for the developer as a convenience feature in addition to selecting the right MessageBundle for the locale.
