Hi,
I have just discovered Generics in Haskell and, writing some code with
GHC, I wondered about the portability of my code. It is possible I
overlooked something in the GHC documentation but I did not found a way
to obtain, let say, the haskell code for the derived classes. I mean,
having

If you use Data.Generics, your code is not portable - no other Haskell
implementation supports the necessary bits.
I can use the -fgenerics to automatically derive
Neil Mitchell a écrit :
Use Derive, which does support Generics:

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:
i'd like to run a ghci command, and capture its ouput as a haskell
String, eg, to pass it on to another ghci command, or to a haskell
function.
It would be possible, but needs a bit of refactoring because all the output
is currently just sent to stdout. I'd go with something like your second

Are type functions checked for termination? If so, where can I find the
details?
