Thanks Joey, AmyNow I want to go 'backwards'.For example I have Language.Haskell.Exts.SyntaxI want to dig into it. Where/How do I start?

Using either Hayoo or Hoogle, search for "Language.Haskell.Exts.Syntax". Click on the results to find out more about this module (what package it's in,

what

...

methods it contains, etc.) Does that answer your question?

Trying out the graphviz package...

$ cabal list|grep -i graphviz gives cabal: <stdout>: invalid argument and nothing else

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...

...

But still $ cabal install graphviz still seems to install

What gives?
