The Arch Haskell group maintains AUR packages for Haskell. The Arch Haskell packages make up around 10% of total AUR packages (~2000 packages).

To make the task of implementing the Arch Haskell policy of tracking AUR feasible, we take two approaches:

  • massive automation of Hackage to AUR regular conversion, via cabal2arch
  • group participation in updating packages.

The first step ensures a consistent user experience:

  • cabal2arch should be used to generate all Haskell AUR packages,
  • which ensures all naming conventions and other policies are followed,

The second point ensures the Arch Haskell project isn't vulernable to "bus errors" where a user burns out.

The job of an Arch Haskell group maintainer

The concern of an Arch Haskell maintainer is as follows.

  • Ensure AUR tracks Hackage versions of packages.

To do this, the following work is done:

  • Watch the Hackage RSS feed
  • When new packages appear, attempt to build and upload them, with the "build" script (below).

The "build" script

The "build" script is a shell program that wraps cabal2arch. You should always have the latest version of cabal2arch installed. The set of tools you need to run this script are:

  • The haskell-archlinux package.
  • cabal2arch
  • aurploader
  • feed-cli

  1. !/bin/sh

cd /tmp/ set -e

project=`cabal2arch $* 2>&1 | tail -1 | sed 's/Created *//' | xargs basename | sed 's/\..*$//'` echo $project cd $project build || exit 1 cd .. echo "Uploading $project.tar.gz" aurploader -k $project.tar.gz

  1. create meta files: update the package list and build success list

tail -1 ~/.cabal2arch.log | update-aur-log

cp /home/dons/aur.xml /tmp/ url=`/home/dons/bin/get-arch-url $project || cat /tmp/link` echo $url feed-cli new-item -t`cat /tmp/title` --description-file=/tmp/desc -u/tmp/aur.xml -l"$url" rm /tmp/link rm /tmp/title rm /tmp/desc echo scp /tmp/aur.xml code.haskell.org:/srv/code/arch/ cp /tmp/aur.xml /home/dons/

And additional script does the work of building the package:

set -e

pkg=`sed -n '/pkgname/{s/pkgname=//;p;q}' PKGBUILD`

if makepkg -f ; then

   echo "$pkg True" >> $HOME/.build-all.log

else

   exit 1

fi
