Hi, I'm newbie in Haskell, and I have some doubts... In this programming language, do we have storable values? Case affirmative, what are the storable types in Haskell, and how can I implement then... thanks! -- Clerton Ribeiro de Araujo Filho Graduando em Ciência da Computação Integrante do PET - Programa de Educação Tutorial Integrante do LIA - Laboratório de Inteligência Artificial Universidade Federal de Campina Grande - UFCG

What exactly is a storable type? -alex

I guess you mean: http://haskell.org/ghc/docs/latest/html/libraries/base/Foreign-Storable.html A type becomes storable by implementing the Storable methods, namely sizeOf, aligment, peek, poke. To this end you can convert to and access the Storable methods of CInt, CDouble and friends.

Not entirely sure what you mean. There is a haskell typeclass called Storable, but it probably isn't what you mean. If you want persistence, serialisation, we have two options: Read/Show is simple, slow and text-based. It's very helpful for debugging but not for high performance. Data.Binary is fast, configurable and binary. That's a good solution for high-throughput persistence. If you need versioning support, then the upper layer of Binary isn't for you. But the "guts" of binary, called Get and Put, make it simple to write your own versioned persistence. Jules
