Dear all, I am pleased to announce the first release of ivy-web after learning haskell for a year. Ivy-web is a lightweight web framework, with type safe routes, based on invertible-syntax, and i18n support, influenced by Django, Snap and Yesod. The features of this web framework: * Type safe routes, specify url-handler mapping in one place. For example, we want a url mapping for blog as "/blog/year-month-day" to Handler Int Int Int, where year, month and day are integers. We can declare as follows: data Blog = Blog Int Int Int deriving (Show, Eq, Typeable) $(defineIsomorphisms ''Blog) instance Handler Blog where get b@(Blog y m d) _ = do t <- liftIO getClockTime return $ responseHtml $ trans' "blog" ++ show b ++ show t rBlog = blog <$> text "/blog/" *> int <-> int <-> int We can reverse this mapping from handler value automatically, thus don't need to construct url string manually in code, avoiding url errors. ghci>url (Blog 2011 9 19) == "/blog/2011-9-19" * Simple yet elegant handler via type class. class Handler a where get, post, put, delete, handle :: a -> Application handle a req = case requestMethod req of m | m == methodGet -> get a req | m == methodPost -> post a req | m == methodPut -> put a req | m == methodDelete -> delete a req otherwise -> unimplemented req * Flexible template system, utilize exsisting libraries such as Blaze-Html and Hastache. * Easy i18n Wraps around i18n library. * TODO: Auth system Port from snap-auth. * TODO: Modular app system like Django The current route system support modular routes very well. Need works in modular config and data files like static template files. * TODO: Persistent library Improving the DSH library is my current preference. The principle of this library is KISS, and "don't reinvent the wheel" by reusing existing state-of-the-art libraries.
