ghc-wizards

'wizards' is a package designed for the quick and painless development of /interrogative/ programs, which revolve around a "dialogue" with the user, who is asked a series of questions in a sequence much like an installation wizard. Everything from interactive system scripts, to installation wizards, to full-blown shells can be implemented with the support of 'wizards'. It is developed transparently on top of a free monad, which separates out the semantics of the program from any particular interface. A variety of backends exist, including console-based "System.Console.Wizard.Haskeline" and "System.Console.Wizard.BasicIO", and the pure "System.Console.Wizard.Pure". It is also possible to write your own backends, or extend existing back-ends with new features. While both built-in IO backends operate on a console, there is no reason why 'wizards' cannot also be used for making GUI wizard interfaces. See the github page for examples on usage: <http://www.github.com/liamoc/wizards> For creating backends, the module "System.Console.Wizard.Internal" has a brief tutorial.
