I agree that preprocessing code shouldn't be hsc2hs specific. I prefer
c2hs myself. But hsc2hs is distributed with ghc, which makes it as
official as a good many other parts of "modern Haskell".
I also agree that making cabal-ghci work nicely would be ideal, but I don't
think it can be done with
Which FRP frameworks have you been looking at?
In my experience, the most publicized leaks have been time leaks, which are
a particular type of memory leak related to switching. However, the
presence of time leaks mostly arises in terms of the FRP implementation.
Arrowized FRP (e.g. Yampa, netwi
While hsc2hs is a popular FFI preprocessor, it is not the only one.
There is also greencard and a few others.
While hsc2hs can usually get the job done -- it's not clear that it is
really the best choice. I think the Haskell FFI got to the point that
it was 'just good enough' and then people lost

Thanks, it works perfectly like that.

Hi haskellers!
I am trying to make a DSL able to describe a voting system. That DSL should
be able to describe many different voting procedures:
unanimity or majority, open or secret ballot, one or two turns... It should
also work for referendums (yes/no question) or elections (electing one or

Hello, Cafe!
I've heard that one of the problems of FRP (Functional Reactive
Programming) is that it's easy to create memory leaks. However I cannot
find any natural examples of such leaks. Could anybody post some
(pseudo)code demonstrating this phenomenon? Preferably something that
arises when on

How about having a `ghci` command for cabal?
I don't think cabal can provide that. Let's say you're inside a 'cabal
ghci' session. If you modify the hsc file and reload i

I agree. I hope that ByteStrings will be replaced by a Storable.V
Hi Tom,
