Re: [Haskell-cafe] file splitter with enumerator package

blah = do fp <- openFile "file" ReadMode run_ $ (ET.enumHandle fp $= ET.lines) $$ printChunks True printChunks is super duper simple: printChunks printEmpty = continue loop where loop (Chunks xs) = do let hide = null xs && not printEmpty CM.unless hide (liftIO (print xs)) continue loop loop EOF = do liftIO (putStrLn "EOF") yield () EOF Just replace print with whatever IO action you wanted to perform.

Sorry, I'm only beginning to understand iteratees, but then how do you access each line of text output by the enumeratee "lines" within an iteratee?

If you used Data.Enumerator.Text, you would maybe benefit the "lines" function:

lines :: Monad m => Enumeratee Text Text m b

It gets arbitrary blocks of text and outputs lines of text.

But there is something I don't get with that signature: why isn't it: lines :: Monad m => Enumeratee Text [Text] m b ??

Lists of lines of text?

Cheers, =)
