Hi Johannes,
The answer is:
A) You can't, the way haskell-src-exts is built. You need to specify the
%partial directives in the happy grammar, so without editing
haskell-src-exts there's no way you could tack on partiality to the existing
parsing primitives.
B) It's a great feature request (to
Hi all,
I'd just like to add that I succeeded in building gtk2hs in Windows XP 64bit
with GHC 7.0.2, using the 2.16 bundle from [1] and following the
instructions in [2].
However, running the test program of [2] still fails at runtime with The
procedure entry point g_assertion_message_expr could
Thanks for supporting the idea.
I already export a partial parser for top-of-file pragmas,
I see. What I don't see is how such a parser would return the rest of input.

I use

If it's a common pattern, you can even do
opts f _ _ (Opt1 x) = f x
opts _ g _ (Opt2 x) = g x
opts _ _ h (Opt3 x) = h x
. Functions are easier to mess around with than case

If you have only one alternative, then you can simply do:
Opt1 - someIO
E.g., if you are _sure_ that foo returns always a 'Just' within a monad you
can perfectly do :
Just x - foo

Hi Pedro,
Perhaps the libglib-2.0.0.dll that is getting loaded is not the one you
want. You should be able to use a tool like process explorer [1] to see
which specific dlls are getting loaded when you run.

Hello tsuraan,
Most often, when we multi-pattern-match on the return value of a monadic
computation, we talk about Maybe or Either or [], and I often find
myself doing this:
someIO1 :: IO (Maybe A)
someIO2 :: IO (Either A B)
result1 - someIO1 = maybe ...
result2 - someIO2 =

Hi all,
I'm having trouble compiling unix-compat with GHC 7.0.2. I'm fairly
certain that other users are not running into this, but I'm not sure
what would be wrong on my system. Here's the error I'm getting:
Resolving dependencies...
Configuring unix-compat-0.2.1.1...

I've got the same problem.
I don't have acces to the computer where I've go the problem (my home mac).
But if I remember correctly
cabal install unix-compat -V3 yielded more output, the problem
was due to lbutil.h, that was not present. I've experienced the same problem
on an EC2, with a

Thanks Pieter and Paulo, that solved the problem perfectly.
And I'm not surprised you stumbled upon this while installing Yesod,
that's what I was doing too ;).
