consider this :
i want load a 4G file(or some bigger file) ,and the process data operation
just like 010 to 101( XOR bits ) , is it some efficient function down it ?
such hPutStr hPutChar is Char layer , is exist bit layer operations?
thanks for any help

Trying out the graphviz package...
$ cabal list|grep -i graphviz
gives
cabal: <stdout>: invalid argument
and nothing else
But still
$ cabal install graphviz
still seems to install
What gives?

Your example works great for me. What OS are you using, and what
version of cabal?
You could also try:
> cabal list graphviz
But that doesn't give you all of the power of regular expressions.

$ cabal --version
cabal-install version 0.10.2
using version 1.10.1.0 of the Cabal library
[I just did a cabal update cabal. Did not do anything as far as I can see]
$ uname -rv
2.6.32-5-686 #1 SMP Tue Mar 8 21:36:00 UTC 2011
$ cat /etc/debian_version
wheezy/sid
On a related note I find a lot of libghc6-something-or-other which are all
described as dummy packages.
Is Debian not the best system to play around with Haskell?
I gather gentoo is where the most haskell development happens...

My only guess is that something is odd about your terminal - I've
never seen that error message before, on linux or anywhere else.

I used to do Haskell development on Ubuntu - I would install the base
libraries from apt, and then use 'cabal' user installs to do the rest.
These days I work on a Mac, where I start with the Haskell Platform
installer.
There's an active Debian+Haskell group; I don't know much about gentoo
(maybe they don't advertise as much).
Sorry I couldn't be of much help with the odd error.

It seems to be happening elsewhere also:
http://hackage.haskell.org/trac/hackage/ticket/856
Also its more likely a locale issue than a terminal one because I get the
same error when I replace the pipe with a redirection to a file.
And yet my locales dont seem to be odd in any way (I can see)
$ locale
LANG=en_US
LANGUAGE=
LC_CTYPE="en_US"
LC_NUMERIC="en_US"
LC_TIME="en_US"
LC_COLLATE="en_US"
LC_MONETARY="en_US"
LC_MESSAGES="en_US"
LC_PAPER="en_US"
LC_NAME="en_US"
LC_ADDRESS="en_US"
LC_TELEPHONE="en_US"
LC_MEASUREMENT="en_US"
LC_IDENTIFICATION="en_US"
LC_ALL=
$ locale -a
C
C.UTF-8
en_US
en_US.iso88591
en_US.iso885915
en_US.utf8
