cabal-rpm

cabal-rpm is a tool for RPM packaging of Haskell Cabal-based packages. It interacts with yum/dnf to install build dependencies and can also act as a cabal-install wrapper installing dependencies packaged in Fedora before running “cabal install”.

Cabal-rpm was originally created by Bryan O’Sullivan (see README.orig) but has since been updated to work with current Cabal and Fedora Packaging Guidelines replacing cabal2spec. It is used by Fedora and OpenSuSE. It is licensed under the terms of the GPL version 3 (see the COPYING file).

You can build from source as normal by running cabal install or via Hackage with cabal install cabal-rpm.

Requirements

cabal-rpm assumes you are using ghc-rpm-macros for Haskell RPM packaging. It currently needs Cabal 1.10 or later to build (ie ghc7), but it should not be hard to patch it to build at least for ghc-6.12.

Installation

The package is on Hackage. If you have cabal-install (part of Haskell Platform) you can install simply with

$ cabal install cabal-rpm

Usage

To create a .spec file for a Haskell src package in the current dir:

$ cblrpm spec

or directly on a .cabal file:

$ cblrpm spec path/to/mypkg.cabal

or on a package source dir:

$ cblrpm spec mypkg-0.1

You can also package directly from hackage:

$ cblrpm srpm somepkg

or

$ cblrpm local somepkg-0.1

will unpack the (latest) ‘somepkg’ package from hackage (if the dir does not exist, otherwise it uses the existing dir), create a spec file for it, and build it.

cblrpm creates .spec files in the current dir and if a .spec file already exists it will append .cblrpm to the generated filename to avoid overwriting an existing file.

$ cblrpm install [pkg][-ver]

will yum/dnf install available missing dependencies and run “cabal install” to build the package.
