Thanks, that does indeed work, but it still requires that unsafe there so

Hi everyone,
I'm pleased to announce a new package I've just uploaded to hackage:
language-sh. It's a set of modules for parsing, manipulating, and
printing sh-style shell scripts. It's being developed alongside shsh,
the Simple Hakell Shell (available at http://code.haskell.org/shsh/,

Hi,
I'm having some difficulty specifying dependencies in my .cabal file
for a package I'm looking to upload to hackage soon. The difficulty
is as follows. I basically want to specify
parsec (= 2.1 3.0.0) || ( 3.0.0 4)
The problem is that 3.0.0 as it exists on hackage is missing a
Hi,
I'm trying to write a small module for conveniently writing functions
that can return any of a finite number of types. That is, I'd like to
be able to write something like
foo :: StringOrInt t = String - IO t
This is pretty easy to do if I hard-code the classes as above, but I
run into
Hi,
I was noticing recently that there seems to be a problem with Hoogle
and Haddock. In particular, I just hoogled bracket and got the
following result:
bracket :: IO a - a - IO b - a - IO c - IO c
Clearly this is the wrong type, as it should be
bracket :: IO a - (a - IO b) - (a
Hi,
I've been trying out the new System.Process and have found it to be
very useful. I was wondering what the plans for it were - I'd rather
not give up support for older versions of ghc just because I want to
use createProcess. Are there plans of releasing process-1.0.1 so that
it's compatible

Hi,
I'm trying to understand how to get pipes working in Haskell, in
particular with the revamped System.Process (though I've tried similar
experiments with System.Posix.IO and Control.Concurrent).
Specifically I'm trying to concatenate the output of two system calls
into the input of a third.

Is there a write up on what makes an implementation lazy vs strict?
I would be interested in seeing this, too!
I like to better understand the trade off between the two and use cases
where one is better than the other.
