How to split a string in Haskell?

Question

Is there a standard way to split a string in Haskell?

lines and words work great from splitting on a space or newline, but surely there is

Answer 1

Try this one:

import Data.List (unfoldr)

separateBy :: Eq a => a -> [a] -> [[a]]
separateBy chr = unfoldr sep where
  sep [] = Nothing
  sep l  = Just . fmap (drop 1) . break (== chr) $ l

Only works for a single char, but should be easily extendable.
