Re: [Haskell-beginners] [IO String] to IO [String]

Try sequence :: Monad m => [m a] -> m [a] I thinkg sequence f :: IO [String] should be what you want. On 03/31/2013 12:19 PM, Ovidiu D wrote:

I have the function f which reads lines form the stdin and looks like this:

f :: [IO String] f = getLine : f

What I don't like is the fact that the line processing I'm doing will have to be in the IO Monad

I would like to make this function to have the signature f : IO [String] ...such that I can get rid of the IO monad and pass the pure string list to the processing function.

Can I do this?

Thanks
