Registering MonoRail Extensions Programatically

Hammett inspired me to switch from XML configuration to programmatic configuration of MonoRail with this blog post. But he didn't discuss how to configure MonoRail extensions. I searched around through the source and came up with this solution:

        public void Configure(IMonoRailConfiguration configuration)

        {

            configuration.ViewEngineConfig.ViewPathRoot = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Views");

            configuration.ViewEngineConfig.ViewEngines.Add(new ViewEngineInfo(typeof(NVelocityViewEngine), false));

 

            configuration.ConfigurationSection = new MutableConfiguration("monorail");

            configuration.ConfigurationSection.Children.Add(

                new MutableConfiguration("exception")

                    .CreateChild("exceptionHandler")

                    .Attribute("type", typeof(EmailHandler).AssemblyQualifiedName)

                    .Attribute("mailTo", "to@email.com")

                    .Attribute("mailFrom", "from@email.com"));

 

            configuration.ExtensionEntries.Add(

                new ExtensionEntry(typeof(ExceptionChainingExtension), new MutableConfiguration("")));

        }

This code sets up the EmailHandler that comes with MonoRail.
