lens ==== [![Build Status](https://secure.travis-ci.org/ekmett/lens.png?branch=master)](http://travis-ci.org/ekmett/lens) This package provides families of lenses, isomorphisms, folds, traversals, getters and setters. These lenses are compatible with those from lens-family, lens-family-core and lens-family-th, but they provide a great deal of additional flexibility in their composition. Example ------- ghci> :m + Control.Lens Data.Text.Lens ghci> anyOf (traverse.text) (=='y') ["hello"^.packed, "goodbye"^.packed] True Contact Information ------------------- Contributions and bug reports are welcome! Please feel free to contact me through github or on the #haskell IRC channel on irc.freenode.net. -Edward Kmett
