It seems that there are changes in the OpenGl library during the last
month. So I decided to load a really young cvs version of the ghc

My Problem is, that I also need the wxHaskell
Hi,
Could you tell us what command line was supposed to generate the
Map.d.in or Map.d file? It may be a bug, there were a few changes in
the driver recently.
Cheers,

I hope I can help you. It would be better Daan would have a look, because it
is his code and he knows
Hi!
I'm working on an IDE for Haskell, written in Haskell.
Currently, I'm looking for a way to parse .hs-files for a module browser
and I recall that Simon Marlow was going to release GHC as a package
soon.
We could also use that package to compile source code without invoking ghc
as a separate

you can get Haskell to derive it for you.

Hello everybody.
I'm working on a haskell project in which I need to evaluate haskell expressions
that are given in an input File.
For instance:
A file containing Peter==Peter or 3+2==5 or home in [a-z]*sex[a-z]* (see
I need to use regular expressions too) is given as input
The file contents

You may want to look at hs-plugins.
Alternatively, Langhage.Haskell.* in fptools may help you do do what you

Send mail to [EMAIL PROTECTED], saying what's in your libraries, and

Yes I think that was what I needed. ;-) It seems I also need
fsplit :: (Functor f, Functor f') =
(f a, f' b) - (f :*: f') (a,b)

Hi
I have a problem with contravariance in the bananas in space setting.
If you take catamorphism from a function space such as A=A-A to a type
such as BxC, then the negative occurrence of X in the functor GXY=X-Y
swaps around BxC into B+C.
This means that maybe in this particular case
