With the C pre processor you can write different code for windows and non
windows? Can your package achieve the same?
The name alone makes it sound like an alternative to using CPP.

Hi Haskellers,
I am delighted to announce the release of wxHaskell 0.90. This release
represents a significant milestone for us as it includes support for
wxWidgets 2.9.x.
The release is avalable from Hackage and as a darcs repo from
http://code.haskell.org/wxhaskell. Build and installation instr

Hello!
It seems like you would want to use "reifyInstances" in order to get
all of the instances associated with a class. Then, you can match up
the variables in each instance with the variables in the class
declaration, and create a mapping from the class variables to the
instance parameters. T
Hi all, I think this is the right place for the following questions and I
thank beforehand for your answers :-)
I'm experimenting with typeclasses and TH, and I want to define a 'macro'
that works more or less like this:
Given the name of a typeclass and a function, return the expressions

Hi Cafe,
Is there a way to have (some) cabal flags to autoconfigure themselves ?
For example, a SSE flag, i want the configure to default to on
when the building machine has SSE instruction available, and default
to off otherwise.
(of course, it wouldn't affect the user ability to override the
Dear Cafe, I have the following types:
type Computer a b = ( a -> IO ( Maybe b ) )
type Transformer a b c d = Computer a ( b, c -> d )
For example, a SAT solver:
minisat :: Computer CNF Assignment,
and when I use it to solve an application problem
via transformation to SAT, I need
t :: Transfo
Hi Dan:
Just to share a little bit of my humble experience.
I'm also a beginner and I'm intrested in "directory manipulation" related
code.
Tasks such as printing directory in a tree form etc.
So I search on Hackage and found several projects, most notably the
Directory.Tree project. It's a very
Hi Jeremy,
Thank you for your encouraging reply. I understand your points and agree
for the most part, especially with the mentorship discussion that you made.
I wasn't too sure about attempting to work on a more sizeable project
(although I preferred that) but if you are saying that it's a reaso
