Dan Corson suggests: it would be good to have links to latest versions of a package file available for download.
I agree.
for example: something like {{{ http://hackage.haskell.org/packages/archive/arrows/latest.tar.gz }}} would be a link to {{{ http://hackage.haskell.org/packages/archive/arrows/0.4/ arrows-0.4.tar.gz }}} this would greatly simplify automating installs.
I don't agree. Automated installs should not blindly grab the latest version. cabal-install is the right tool for automatic installs.

I ''think'' that making `latest.tar.gz` redirect to the real file name will behave like that. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/251#comment:1 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

That needs an HTTP Redirect response rather than just a symbolic link on the server. It's more work, but possible. I think I should also move all the tarballs for a package into a single directory, to suit tools like Debian's uscan that scan a directory for new versions. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/251#comment:2 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

The index of course does tell you when new versions are available and it tells you for every package in one download. One doesn't have to use cabal-install for this purpose. For example gentoo has a tool to compare a gentoo package repository with the hackage collection to list packages that are out of date. We wrote it in Haskell but something much simpler using bash + wget + tar + find would be fairly straightforward too I expect. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/251#comment:3 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
