With a fresh install of ghc and only ghc, I have a handy-dandy set of documentation rooted at /usr/share/doc/ghc/html. The particularly useful (to me) part is described by libraries/index.html, which points to all the module-specific documentation. Except it doesn't. With just ghc installed, I then added haskell-text, and the documentation isn't updated. I poked around and it appears the documentation under libraries/dist-haddock *is* updated, but the relative paths are broken for most (all?) except the stuff from haskell-text. I also installed haskell-parsec and its documentation shows up only under libraries/dist-haddock. In /etc/pacman.conf, after [core] and before [extra] and [community]: [haskell-core] SigLevel = Optional Server = http://xsounds.org/~haskell/core/$arch Server = http://www.kiwilight.com/haskell/core/$arch [haskell-web] SigLevel = Optional Server = http://archhaskell.mynerdside.com/$repo/$arch Summary: /usr/share/doc/ghc/html/libraries/index.html points to documentation concerning modules shipped with ghc post-install for haskell-text and haskell-parsec runs gen_contents_index, which seems to put their documentation in the index at /usr/share/doc/ghc/html/libraries/dist-haddock/index.html and *NOT* in /usr/share/doc/ghc/html/libraries/index.html /usr/share/doc/ghc/html/libraries/dist-haddock/index.html seems to correctly point to documentation regarding modules from haskell-* packages /usr/share/doc/ghc/html/libraries/dist-haddock/index.html seems to NOT correctly point to documentation regarding modules from the 'ghc' package Did I fat-finger something? Am I wrong to expect all the module docs to be available from /usr/share/doc/ghc/html/libraries/index.html ? I could swear it was previously; maybe it broke during the switch to 7.6? This commit seems relevant: http://www.haskell.org/pipermail/cvs-ghc/2012-January/069567.html but it's not clear (to me) what the difference is between libraries/* and libraries/dist-haddock/*.
