DeepArrow: Arrows for "deep application"

[ bsd3, combinators, control, library ] [ Propose Tags ]

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

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 ->.

Readme for DeepArrow-0.3.2

[back to package description]

The DeepArrow library provides a framework for type-directed composition
of value editors.  For a fuller description and link to documentation,
please see the Haskell wiki page:

  http://haskell.org/haskellwiki/DeepArrow

You can configure, build, and install all in the usual way with Cabal
commands.

  runhaskell Setup.lhs configure
  runhaskell Setup.lhs build
  runhaskell Setup.lhs install

See src/Control/Arrow/DeepArrow/Examples.hs for examples.
