RPM packaging tool for Haskell Cabal-based packages.

This package provides a RPM packaging tool for Haskell Cabal-based packages.

cabal-rpm has commands to generate a RPM spec file and srpm for a package. It can rpmbuild packages, dnf/yum install their dependencies, prep packages, and install them. There are commands to list package dependencies and missing dependencies. The diff command compares the current spec file with a freshly generated one, the update command updates the spec file to latest version from Stackage or Hackage, and the refresh command updates the spec file to the current cabal-rpm packaging. It also handles Hackage revisions of packages. Standalone packages can also be made, built with cabal-install.

cabal-rpm

cabal-rpm is a tool for RPM packaging of Haskell Cabal-based packages. Firstly it creates RPM spec files from the .cabal files of Haskell packages. It can also install build dependencies using dnf/yum, it prefers package versions from Stackage, and can build and install packages and their dependencies recursively as rpm packages. It can also update packages and refresh spec files.

Cabal-rpm was originally created by Bryan O'Sullivan (see README.orig) to create spec files, and was later updated by Jens Petersen to work with current Cabal and Fedora Packaging Guidelines replacing cabal2spec, and extended with many new features. It is used by Fedora and earlier by OpenSuSE. It is licensed under the terms of the GPL version 3 (see the COPYING file).

Requirements

cabal-rpm assumes you are using ghc-rpm-macros for Haskell RPM packaging.

Usage

To create a .spec file for a package:

$ cabal-rpm spec somepkg

By default it will use the package version in Stackage LTS or else the latest version from Hackage.

You can also specify a version if you wish

$ cabal-rpm spec somepkg-0.1

which will create a spec file for it.

cabal-rpm also works in an rpm package source directory or inside the source of a Haskell package:

$ cabal-rpm spec

cabal-rpm 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.

$ cabal-rpm install [pkg][-ver]

will yum/dnf install any available missing dependencies and build rpms of the package. Additionally it will recursively package and install missing Haskell dependencies.

$ cabal-rpm diff

diffs the current spec file with a freshly generated spec file.

$ cabal-rpm update

updates the package to the latest Stackage or Hackage version

$ cabal-rpm refresh

updates the spec file to the current cabal-rpm packaging.

There are more commands: prep, builddep, depends, requires, missingdeps. See the manpage or help output for more details.

Installation

cabal-rpm is packaged in Fedora and EPEL.

It currently needs at least ghc 8 or newer and Cabal 1.18 or later to build.

The package is on Hackage. If you have cabal-install you can install simply with

$ cabal install cabal-rpm

You can also install it with stack install cabal-rpm.

You can also build and install it from source as normal by running cabal install.

Development

The latest source code is available from: https://github.com/juhp/cabal-rpm

More features are planned and patches welcome. See the TODO file for more details.
