Modules come from Haskell packages, most of which can be found on hackage.haskell.org. If you are looking for a module but you don't know which package it comes from then feel free to search using hoogle or hayoo!. Obviously manually checking all the seemingly related packages on hackage is also an option (and still practical for sufficiently narrow categories). Hoogle: http://haskell.org/hoogle/?hoogle=Text.Regex Hayoo!: http://holumbus.fh-wedel.de/hayoo/hayoo.html Thomas On Fri, Oct 16, 2009 at 9:17 PM, zaxis wrote:

In Archlinux i can use Text.Regex as below: import Text.Regex let [y,m,d] = map (\x -> read x::Int) $ splitRegex (mkRegex "-") dateStr

However, in Ubuntu 9.10 it doesnot work reporting no Text.Regex module. So i download and install regex-base and regex-posix from Hackage. But it still doesnot work !

If you installed ghc6 from a package you should do: sudo apt-get install libghc6-regex-* Erik -- ---------------------------------------------------------------------- Erik de Castro Lopo http://www.mega-nerd.com/
