pandoc in the repositories
by Abhishek Dasgupta 24 Feb '09

24 Feb '09

Hi all, pandoc in the [community] repository is by now quite outdated. While there is a haskell-pandoc package in AUR, it cannot be used by people who do not want to install the whole gamut of GHC and the haskell toolchain. I've prepared a PKGBUILD for pandoc 1.1 which depends only on gmp, but makedepends on ghc, haskell-utf8-string and haskell-zip-archive. Is it OK if I move these to [community]? Cheers, Abhishek

lhs2tex
by George Giorgidze 24 Feb '09

Hi Arch-Haskellers, CC Mateusz Herych, Does anyone know why is lhs2tex outdated in AUR? I suggest to (automatically) package it using cabal2arch like most of the Hackage packages are packaged. If it requites some manual intervention I suggest to ask Matesz (the current maintainer) to update it. In case if he is busy and does not have enough time I (or some one else who volunteers) would do it. I think lhs2tex is a nice, useful and mature piece of software and does not deserve to be outdated in AUR ;). IMHO, it is well placed to be included in the community repo as well. Cheers, George -- George Giorgidze http://www.cs.nott.ac.uk/~ggg/

Arch packages and/or Cabal-install ?
by papa.eric＠free.fr 22 Feb '09

22 Feb '09

Hello... a newbie question (not installed Arch yet, only decided to give it a try... new to this list, too) : It seems that haskell packages on Arch can be reliably managed by either cabal-install or arch packages. I suppose that mixing both is is not recommended ? e.g. using an arch package if it exists else caba-install, or obtaining one by arch yaourt but then upgrading it by cabal install... So, what would be the drawback of installing as arch packages the minimum to have GHC and cabal-install, and then using exclusively cabal-install to install and upgrade haskell stuff ? What does arch packages bring more than cabal-install, since both manage dependences ? Thanks, and sorry if the question is naive... Eric

Near past, present & future

Hi guys, As some of you may have noticed (perhaps with some pain), ghc-6.10.1 has been in testing for over a week now. Some performance regressions have been noticed, and some packages fail to build on it (most due to trivial problems). That's why it won't be coming to extra too soon. Nevertheless, I'm using it as my main platform for development, and it works well. Presently, the next big thing will be the Haskell Platform, which is basically a bundle of important packages. We will try to get the packages in it to extra, with a "haskell-platform" group defined. So pacman -S haskell-platform should get you all the goodies now and forever. All this is good. Now for a bit of controversy. I'm not very happy about how AUR works for us. We get good PKGBUILDs and rather painless installation through yaourt, but it feels quite clumsy to me. For at least the following reasons: 1) When we update ghc, there's no good way to update all the packages in AUR that depend on it. Best way to cleanup is pacman -Rc cabal-install, which kinda works but... And if I go back to the other ghc version (like I often did when playing with 6.8.2 and 6.10.1), my old packages are lost. 2) Pacman just doesn't support the sort of versioning we'd need for this. By principle. 3) yaourt often builds dependencies twice. Perhaps just a simple bug in yaourt. There's a simple solution to all these problems: for packages outside the Haskell Platform, we start using cabal-install. This has worked for me very well, and I'm not sure if I see why we should have Arch packages for everything. Of course also we would have some higher profile stuff in extra (like darcs) and community (like xmonad). Any feelings? Rest assured, I'm not gonna go at this blindly. --vk (dons an asbestos suit)
