Documentation

escapeHtml :: String -> String Source

scaffold :: (Scaffolded a, Monad m) => String -> a -> Dlg m a Source

The scaffold function builds a user interaction to display and collect information. In a finished web application, this should generally be replaced with a better mechanism for rendering pages, such as a templating engine, XSLT, or something of the sort.

class Scaffolded a where Source

The Scaffolded type class represents data that can be included in a form. To make it easy to compose several of these in a page, rendering and parsing are parameterized with prefix strings so that they may be made unique across a page. Methods render :: String -> a -> String Source parse :: Monad m => String -> ServerPartT m a Source Instances Scaffolded Bool Scaffolded Int Scaffolded String Scaffolded () (Scaffolded a, Scaffolded b) => Scaffolded (a, b) (Scaffolded a, Scaffolded b, Scaffolded c) => Scaffolded (a, b, c)
