Re: [Haskell-cafe] How to split this string.

max writes:

I want to write a function whose behavior is as follows:

foo "string1\nstring2\r\nstring3\nstring4" = ["string1", "string2\r\nstring3", "string4"]

Note the sequence "\r\n", which is ignored. How can I do this?

cabal install split then do something like import Data.List (groupBy) import Data.List.Split (splitOn) rn '\r' '\n' = True rn _ _ = False required_function = fmap concat . splitOn ["\n"] . groupBy rn (though that might be an abuse of groupBy) -- Jón Fairbairn Jon.Fairbairn@cl.cam.ac.uk
