DeepArrow

This library provides a framework for type-directed composition of value editors (non-syntactic transformations). The tools enable "deep function application" in two senses: deep application of functions and application of deep functions. These tools generalize beyond values and functions, via the DeepArrow subclass of the Arrow type class. For more information see: The project wiki page http://haskell.org/haskellwiki/DeepArrow Application of deep arrows for composable interfaces in the TV library: http://haskell.org/haskellwiki/TV The motivating idea and paper Tangible Functional Programming: http://conal.net/papers/Eros The primary module is Control.Arrow.DeepArrow. Examples in Control.Arrow.DeepArrow.Examples. Note: Many of the type signatures use infix type operators (as in a~>b). In reading the documentation and code, be aware that infix operators bind more tightly than ->. © 2007-2012 by Conal Elliott (http://conal.net); BSD3 license.
