All we need is someone to do the work :-) There is a bug tracking the progress on this issue here: http://code.google.com/p/ndmitchell/issues/detail?id=80 - but its a reasonable amount of work, touching lots of different parts of the Haskell infra.

The files created by the 'hoogle data' command in /usr/share/hoogle should probably all be world readable. The directories should all be world readable and world executable (ie allow anyone to chdir into it). If so, I'll make a new release that just changes the file creation mask to the above during hoogle data (and sets it back after). That makes sense. If you have a darcs repo of the code (or even a tarball), I can check it before create a package.

Neil Mitchell wrote: Hoogle 4.1.3 is now released, which reads and writes Hoogle input files in UTF8 throughout. Please let me know if this doesn't fix your problem. Thanks Neil for the quick response. That definitely has fixed thet problem. The next problem is that hoogle installed as a Debian package would install as root as /usr/bin/hoogle. Then, when I run hoogle data it wants to install the database at /usr/share/hoogle/hoogle-4.1.3/databases which fails because I'm not running as root. So, to install the databases I need to run sudo hoogle data (which is acceptable), but then an unprivelidge user can't run hoogle because they don't have read permission on the database. The solution would be to set the umask before writing the databases. Something like (untested): import System.Posx -- Set umask to world read/execute. Save old umask for -- restoration later. oldumask - setFileCreationMask 0o022 If you need help with this, let me know.
