Re: [Haskell-cafe] serialize an unknown type

Hi, Sorry if it was not enough explicit. I want to write functions like this: serialize :: (Show a) => Event a -> IO () deserialize :: (Read a) => IO () -> Event a The functions would write and read the data in a file, storing/retrieving also the type "a" I suppose...

Nobody on this one? Here is a simplified version:

data Event a where InputChoice :: a -> Event a

How to serialize/deserialize this?

Cheers, Corentin

Hi the list! I have a simple question, how can I serialize/deserialize a structure like this:

data InputChoice c deriving Typeable data Event a where InputChoice :: (Eq c, Show c) => [c] -> c -> Event (InputChoice c) (...)

I'd like that the values of type "c" get serialized to a String... That's the easy part, but for deserializing, oops!

Cheers, Corentin
