Re: Derived instances

Neil Mitchell a écrit :

Use Derive, which does support Generics: http://www-users.cs.york.ac.uk/~ndm/derive/

If you care about portability, and are not using some of the more advanced features of Generics, then you might want to take a look at Uniplate: http://www-users.cs.york.ac.uk/~ndm/uniplate/

Uniplate does generic traversals, but will work on all Haskell 98 compilers, to some degree - read the paper for exact details.

Thanks

Thanks for these links. I will check the tool, but they seem to fit perfectly for my purposes. Fernand
