Multilingual applications

You can either create own classes to load the languages or use the only implemented version (yaml files). To create your own, look at languages\languagemanager and languagecategory interfaces.

The language implementation uses categories to divide language translations into more manageable classes. Each category can be loaded from different sources.

The ViewController contains some magic which makes it really easy to use the language. It uses the controller name to find the correct category and the threads locale to select the correct language.

public class ItemController : ViewController
  public string Welcome()
    // renders public\views\item\welcome.haml which contains the variable "text"
    return Render("text", Language["Welcome"]);

  public LanguageCategory Language
    get { return _langMgr[ControllerName]; }

  public string Submit()
    // validate data
    Validator validator = new FormValidator(Request.Form["user"], Errors, Language);

    //true means that the field is required
    string userName = validator.LettersOrDigits("username", true); 

    // password is letters, digits and all chars specified in Validator.PasswordChars (public static string)
    string password = validator.Password("password", true); 

    if (validator.ContainsErrors)
      return RenderErrors();
      //do something with the validate data

The above code would produce errors like:
Fältet 'Användarnamn' kan endast innehålla siffror och bokstäver.
'Username' may only contain letters or digits.

depending on the language.

YAML files
