Function translationContext
Annotates an interface method or class with translation information.
The translation context contains information about supported languages
and the translated strings. Any translations will be automatically
applied to Diet templates, as well as strings passed to
vibe
.
By default, the "Accept-Language" header of the incoming request will be used to determine the language used. To override this behavior, add a static method determineLanguage to the translation context, which takes the request and returns a language string (see also the second example).
Prototype
TranslationContextAttribute!CONTEXT translationContext(CONTEXT)() @property;
Example
struct TranslationContext {
import std .typetuple;
alias languages = TypeTuple!("en_US", "de_DE", "fr_FR");
//mixin translationModule!"app";
//mixin translationModule!"somelib";
}
@translationContext!TranslationContext
class MyWebInterface {
void getHome()
{
//render!("home.dt")
}
}
Example
Defining a custom function for determining the language.
import vibe .http .server;
struct TranslationContext {
import std .typetuple;
alias languages = TypeTuple!("en_US", "de_DE", "fr_FR");
//mixin translationModule!"app";
//mixin translationModule!"somelib";
// use language settings from the session instead of using the
// "Accept-Language" header
static string determineLanguage(scope HTTPServerRequest req)
{
if (!req .session) return null; // use default language
return req .session .get("language", "");
}
}
@translationContext!TranslationContext
class MyWebInterface {
void getHome()
{
//render!("home.dt")
}
}
