    Elm Comonad Zipper

    type Zipper a
        = Zipper (List a) a (List a)

    This package provides an implementation of a List Zipper as well as its corresponding comonadic interface, namely, the functions extract, duplicate and extend.

    These are useful to perform transformations which depend on the neighborhood of the elements, you can find examples here.

    To run the examples just clone the repo, and run elm-reactor in the examples directory:

    git clone
    cd elm-comonad-zipper/examples
