A function to tie together two sorted Haskell Iterators (Producers from the pipes library).
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 ()
(Just 1,Nothing) (Nothing,Just 2) (Just 3,Just 3) (Just 4,Just 4) (Nothing,Just 5) (Just 6,Nothing) (Just 8,Just 8)
Version 126.96.36.199: Initial commit with example, tests and haddock
Version 188.8.131.52: Added a note that input sequences have to be sorted.
V 1.1.0: Added new function to check ordering of incoming pipes
