Does hjs depend on regex-base ?
by Marc Weber 09 Jul '07

09 Jul '07

hjs -> regex-compat -> regex-base ghc-6.6.1: unknown package: regex-base-0.91 (dependency of regex-compat-0.90) Preprocessing executables for hjs-0.2... Obviously you can't compile regex-compat without regex-base. Thus you can/should assume that you have also regex-base installed if you find regex-compat, right? Is this intentionally? Mmmh This means I must iterate over the whole dependency tree to collect them all. Marc Weber

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

Need a username for Hackage

Hi Ross. (CC cabal-devel) I'm adding all packages from hackage to the nix distribution system. However I'v noticed some small issues. (eg Renaming FilePath -> filepath) Should I fix the issues in nix only or should I fix the packages on hackage? If so I would need an account on hackage. Marc Weber

The way it is now, it looks too much like an error > message. Mmm, good point. Perhaps we could just change the verbosity of that message for now, so that it doesn't appear at the default verbosity level. Duncan

Should HEAD of Cabal be depending on the new library world order?
by Bryan O'Sullivan 06 Jul '07

06 Jul '07

Hi, all - I just pulled a backlog of changes from the HEAD of the Cabal repo, and now I can no longer build Cabal with ghc 6.6.1. This makes working with it while running GHC 6.6.1 a bit awkward, so my poor cabal-rpm tool is stuck in a limbo where I can't easily build it except against a manually hacked copy of Cabal. Is there any chance that we could bless some revision of Cabal that will compile with GHC 6.6.1, give it a name, and then go back and resplit things in preparation for future greatness? If people see some value in this, I can do the necessary legwork. <b

RFC: Cabal-Configurations patch(es)
by Thomas Schilling 29 Jun '07

29 Jun '07

Hi, you just received a longish patch bundle, that together implement Cabal configurations. I realized too late that there's a way to combine this mail with the actual patch, so consider this an addendum. The implementation can read all old Cabal-files (and should do the same), but unfortunately, I had to change the interface of the confHook function, which I assume will break some setup files. The documentation states, that you shouldn't depend on that interface, but then again do people have to use them if they have special requirements. The most important change is, that Cabal files are now parsed to 'PreparedPackageDescription' which requires a run of 'finalizePackageDescription' to get to the actual 'PackageDescription'. This resolving process is potentially very slow (exponential in the number of flags), especially if there is no possible flag assignment. I plan to correct this by adding some minimum SAT solving capabilities, which will however still be exponential in the worst case. For now, the current implementation should be sufficient, though. My testing is far from exhaustive, as I haven't yet found a good way of setting up a suitable test environment without endangering to break my current setup. I am setting up a ghc-HEAD installation, but there is currently a build error stopping me from it. Incidentally, Cabal itself now needs configurations to build with ghc-head as well as ghc-6.6.1. That said, I'd like to ask you to review the patches and possibly also test it on your projects. A preliminary HOWTO is at: http://hackage.haskell.org/trac/hackage/wiki/CabalConfigurations Thanks, / Thomas
