Hello everyone Please visit these to pages: http://www.haskell.org/ghc/docs/6.8.3/html/libraries/haskell98/CTypes.html -- ver 0.9 http://www.haskell.org/ghc/docs/6.10.1/html/libraries/haskell98/CTypes.html -- ver 2.3.0 They show documentation produced by Haddock. The problem is: on the second page (for GHC 6.10.1) there is no information about exported module:

module CTypes (module Foreign.C.Types) where import Foreign.C.Types

It seems it has something to do with bug fixed by 2.3.0 version of Haddock: (see http://haskell.org/haddock/CHANGES.txt )

Changed in version 2.3.0: (...) * Fix a bug that made hidden modules show up in the contents & index pages (...)

This is really annoying, especially that documentation on page doesn't contain links for source code. I think this should be fixed too. I also checked that information about exported modules appears when there is more thing to export like in Control.Concurrent. I didn't file a Haddock bug since I failed to make minimal example that reproduces the bug. A.hs:

module A (module B) where

import B

B.hs:

module B (one,two) where

one :: Int one = 1

two :: Int two = 2

Turns out to generate good documentation. Perhaps there is something more to be done to actually trigger the bug. I attach my testing suite (A.hs, B.hs, Makefile, results). All best Christopher Skrzętnicki
