[Haskell-cafe] Conduits and Unix Pipes

Has anyone built an adapter between unix pipes and conduits? Something like: upipe2conduit :: String -> Conduit Char Char let someLines = "hello\nworld" nLines <- (read . runResourceT $ sourceList someLines $= upipe2conduit "wc -l" $$ consume) :: Integer If this has been done, is it on hackage? Thanks, - clark
