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

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)

This is the simplest solution of the proposed, in my opinion. Thank you very much.
