DeepArrow-0.3.3: Arrows for "deep application"

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

This page and the module documentation pages have links to colorized source code and to wiki pages where you can read and contribute /user comments/. Enjoy!

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), a recent extension to GHC. In reading the documentation and code, be aware that infix operators bind more tightly than ->.
