Packaging a Cabal library package in 10 easy steps

This process requires the haskell-utils package.

Here is an example on was created a new Debian package out of an Haskell Cabal library package: mtl.

  1. wget http://hackage.haskell.org/packages/archive/mtl/1.0/mtl-1.0.tar.gz -O haskell-mtl_1.0.1.orig.tar.gz
  2. tar -zxf haskell-mtl_1.0.1.orig.tar.gz
  3. cd mtl-1.0
  4. mkdir -p debian/varfiles
  5. Create debian/varfiles/varfile with your favorite editor: 
        maintainer="Ian Lynagh (wibble) <igloo@debian.org>"
    short_description="Haskell monad transformer library for GHC"
    long_description=" MTL is a monad transformer library, inspired by the paper \"Functional
    Programming with Overloading and Higher-Order Polymorphism\",
    by Mark P Jones (<http://www.cse.ogi.edu/~mpj/>), Advanced School
    of Functional Programming, 1995."
    c_dev_libs=""
    extra_build_deps=""
    (Pay attention to the leading space in long_description. It's necessary due to the format of Debian's control file.)
  6. Create debian/copyright with your favorite editor: 
        Debianised by ...
    Author ...
    Copyright: BSD ... /usr/share/common-licenses/BSD ...
    EOF
  7. dch --create -D unstable --package haskell-mtl --newversion 1.0.1-1
  8. update-debian-haskell-files
  9. debian/rules update-generated-files
  10. debuild -us -uc

With luck the .cabal file will provide most of the text for steps 5 and 6.

When making future changes, apart from adding a changelog entry (use dch), only steps 9 and 10 need to be repeated.

Even if packaging Haskell libraries seems easy, the Debian Policy and the Developers Reference contains a lot of valuable informations on how to create a policy compliant Debian package.

Please subscribe to the debian-haskell mailling-list if you are interested in creating new Haskell packages for Debian.
