How do I find out which module a package is loaded from?
I have xmonad-contrib-0.9.1 and xmonad-contrib-0.9.2 installed. I did
$ sudo ghc-pkg hide xmonad-contrib-0.9.1
but it seems the module used is still xmonad-contrib-0.9.1 (I *think*).
I have in my xmonad.hs the line
"import qualified XMonad.Util.Dzen as Dzen" which works - but only with
the legacy functions (e.g. dzen , but *not* dzenConfig), hence my hobby
conclusion that it is xmonad-contrib-0.9.1 that is used -- despite the
fact that it is "hidden", but what do I know?
So how *does* GHC find a package, and within it, a module? I have been
using "the Google" and the documentation for a while now, but I've come
up emtpy handed. Is the module system really so badly documented?
