Hi all,
Is there some sort of a guide for converting existing code Conduit 0.4?
What happened to Control.Monad.Trans.Resource.with?
What happens to stuff that used to to have a type "C.Source m a" which
now seems to need type "C.Pipe Void a (ResourceT m) a"?
Cheers,
Erik

I transfered my code from 0.3 to 0.4 without any changes. There are type
synonyms in Conduit for that.
Changes were from 0.2 to 0.3. Michael discribed it here

Actually, in 0.4
no changes with Control.Monad.Trans.Resource.

I'm not providing it, the compiler is suggesting it:
Network/HTTP/Proxy.hs:835:47:
Couldn't match expected type `ByteString' with actual type `()'
Expected type: C.

I've been reading the various posts you've been making about Conduit,

Hello!
I am pleased to announce the release of plugins-1.5.2.1:

The plugins library provides facilities to compile and dynamically
load/link Haskell code into a running Haskell application. (The

Hello,
I will update the description. The documentation is not on hackage yet
because the haddock builder only runs a few times a day. That should
correct itself in a few hours -- unless the build fails for some
reason.
However, the API has not changed from the previous version, so these
docs are
I'm pleased to announce the release of version 0.1.0 of pipes-core, a
library for efficient, safe and compositional IO, similar in scope to
iteratee and conduits.
http://hackage.haskell.org/package/pipes-core
This release fixes a mistake in the previous version which violated the
category laws in
A concurring opinion here, and an example.
iff :: Bol -> a -> a -> a
iff True x _ = x
iff False _ x = x
f, g :: Bool -> Bool
f x = x
g x = iff x True False
Are these two functions equal? I would say yes, they are. Yet once you
can pattern match on functions, you can easily tell these functions

It's not that tricky at the end. Just install LLVM 3.0 and some OS
supplied unregisterised GHC. Grab 7.4.1

It should, if not report a bug since I regularly test on ARMv
