pipes-ordered-zip-1.0.0.1: README.md

# pipes-ordered-zip

A function to tie together two sorted Haskell Iterators (Producers from the [pipes library](http://hackage.haskell.org/package/pipes)).

Example:

    import Pipes (runEffect, (>->), each)
    import qualified Pipes.Prelude as P
    import Pipes.OrderedZip (orderedZip)

    main = do
        let a = each [1,3,4,6,8] -- has to be ordered
            b = each [2,3,4,5,8] -- has to be ordered
        let mergedProd = orderedZip compare a b
        _ <- runEffect $ mergedProd >-> P.print
        return ()

prints:

    (Just 1,Nothing)
    (Nothing,Just 2)
    (Just 3,Just 3)
    (Just 4,Just 4)
    (Nothing,Just 5)
    (Just 6,Nothing)
    (Just 8,Just 8)
