Hi,

probably a PEBCAK, but working on updating all our Haskell-related OpenBSD ports, I've currently the problem, that, e.g. for Crypto the Haddock-generated documentation doesn't gets installed where I want it installed ;-)

Is this configurable at Cabal/Haddock runtime? I'd try to play with --datadir, but this appears a little bit dangerous as a general approach, since some packages my actually come with real data, which should *not* go into $prefix/share/doc, of course.

Currently the docs do just use --datadir= and --datasubdir= .

Or do I have to patch Cabal? If so, what about adding just another FilePath like docdir to Distribution.SimpleLocalBuildInfo and use it for the documentation?

I think it'd be perfectly reasonable to follow the lead of autoconf here and have slightly finer grained control with respect to the kinds of files we're installing. Autoconf distinguishes docs (and various kinds of docs, html, ps, pdf, man etc) from the generic datadir. So yes, if you want to extend cabal in this direction I'm happy to review patches. Duncan
