Re: [Haskell-cafe] [Haskell-beginners] how to modify show for a list of certain types

Check out "unlines"! On Sat, Apr 2, 2011 at 4:32 PM, Manfred Lotz wrote:

Hi there, I have a list of say type Record which I write to a file and read back from the file if required.

The list's content is a single line in the file it doesn't matter how many records the list contains.

I would like to modify show for type Record in a way that show does work like the normal show but additionally adds a newline at the end of the string.

I'm a bit lost how to do that. Any idea?
