It just unregisters libraries not delete them actually. But I guess it

The "cabal-delete" command does delete libraries and I'm planning to
integrate "cab" and "cabal-delete". But the author of "cabal-delete"
is now suffering from the Tsuna

Hello cafe,
Let me announce a maintenance command of Haskell cabal packages.
http://www.mew.org/~kazu/proj/cab/en/
"cab" is a MacPorts-like maintenance command of Haskell cabal
packages. Some part of this program is a wrapper to "ghc-pkg" and
"cabal".

There were a couple of bugs in
It works fine up to the point when makefdCallback tries to use
GHC.Conc.threadWaitRead on fd
So my example is simplifed in to this:
import System.Posix.IO
import GHC.Conc
main = do
fd <- openFd "/etc/passwd" ReadOnly Nothing defaultFileFlags

You mean a signature with no type variables and types that are know to GHC

thanks for pointing out the openshake implementation.
when i remember correctly neil mitchell mentioned s.th. at the haskell
implementors workshop about making shake available sometimes later.
it's a bit sad to see that shake is completely off the table since it

I find this behaviour a little annoying. Sometimes I *want* the thread

Daniel Fischer and Yves Parès gave you good suggestions about
implementing
I don't know if there's a way to disable it, but you can wrap all your
spawned threads with an exception handler that catches BlockedIndefinitelyOnMVar
and ignores it. If the thread blocks indefinitely, it's as good as dead,
so there won't be any difference in behavior.

I am only a sophomore and haven't taken any course in Computational Physics. So
what I would like will be to take a library or program with some excellent
documentation and use it as a base for learning about computational physics
and Haskell. This is one of the things I plan to do in summer.
Hi all,
I have a package[1] which uses some system libraries (Qt to be
precise). On Linux (and I'm hoping Mac), it's able to use pkg-config
to determine which libraries are necessary and where to find all the
files. On Windows, I've been less than successful using pkg-config.
However, I *was* able
Good catch, that was most definitely a space leak in pool. I've

Hi!
Is there a way to disable throwing BlockedIndefinitelyOnMVar
exceptions? Because I am doing small program where I do not care if
some threads block. As at the end user will have to interrupt the
program anyway.
