Haskell SIG

Mission

The mission of the Haskell Special Interest Group is to maintain, grow, and guide the packaging of Haskell projects in Fedora.

Communication

Mailing lists

We have two mailing-lists:

• haskell (archives) for general discussion
• haskell-devel (archives) for bugzilla traffic.

Matrix and IRC

• Matrix room: #haskell:fedoraproject.org

Package versions

GHC and Stackage LTS versions

• F41 has ghc-9.6.6 and Stackage LTS 22
• F39/F40 have ghc-9.4.5 and Stackage LTS 21
• EPEL9 has ghc-8.10.7 and Stackage LTS 18
• EPEL8 has ghc-8.2.2 and Stackage LTS 11

See Haskell_Stackage_LTS and Haskell_Platform for older releases.

See Haskell_GHC_LLVM for llvm version requirements.

GHC X.Y packages

These GHC package are available for current Fedora releases and EPEL 9:

• ghc8.10 (8.10.7) (except epel9)
• ghc9.0 (9.0.2)
• ghc9.2 (9.2.8)
• ghc9.4 (9.4.8)
• ghc9.6 (9.6.6)
• ghc9.8 (9.8.2) [not yet for epel9)
• ghc9.10 (9.10.1) [F41+]

They can be parallel installed.

• If you want to make one of them default install ghcX.Y-compiler-default

Note the former ghc module streams are now deprecated.

Haskell Coprs

• https://copr.fedorainfracloud.org/coprs/petersen/haskell-language-server/
• https://copr.fedorainfracloud.org/coprs/petersen/cabal-install/
• https://copr.fedorainfracloud.org/coprs/petersen/cabal-install-3.8/
• https://copr.fedorainfracloud.org/coprs/petersen/cabal-install-3.6/
• https://copr.fedorainfracloud.org/coprs/petersen/pandoc/

Coprs for EPEL 7

These versions of ghc are available:

• https://copr.fedorainfracloud.org/coprs/petersen/ghc-8.6.5/ (includes cabal-install-2.4.1)
• https://copr.fedorainfracloud.org/coprs/petersen/ghc-8.4.4/ (includes cabal-install-2.2)
• https://copr.fedorainfracloud.org/coprs/petersen/ghc-8.2.2/ (includes cabal-install-2.0 and epel6)
• https://copr.fedorainfracloud.org/coprs/petersen/ghc-8.0.2/ (includes cabal-install-1.24)
• https://copr.fedorainfracloud.org/coprs/petersen/ghc-7.10.3/ (includes cabal-install-1.22 and epel6)
• https://copr.fedorainfracloud.org/coprs/petersen/ghc-7.8.4/ (includes cabal-install-1.18 and epel6)
• https://copr.fedorainfracloud.org/coprs/petersen/stack/ (1.9.3)
• https://copr.fedorainfracloud.org/coprs/petersen/idris/ (1.3.1)

If you have Fedora Haskell libraries installed which are not part of ghc, you will need to remove them all first (easiest just to remove ghc-base) to avoid package dependency conflicts

Tasks

• ghc-9.4
• add cabal-installX.Y
• help improve FedoraReview/plugins/haskell.py
• document ghc and package update workflow (GHC_Update_SOP)
• package larger subset of LTS in Copr

Packaging

New Package Process

• Please use cabal-rpm to generate packages for submitting a package review request.
  • It should follow the current Haskell Packaging Guidelines.
  • Please add haskell-devel@lists.fedoraproject.org to the CC list for your review request bug.
• You can use cabal-rpm diff when reviewing packages to check differences from the templates.
• New packages can optionally be added to https://release-monitoring.org/ to track Stackage (or Hackage if not in Stackage).

Package reviews

"ghc" or "haskell" package reviews

Other links:

• Closed haskell-devel package reviews
• Old Haskell-pkg-reviews tracker is no longer used

(Previously we tracked package review requests CC to haskell-devel@lists.fedoraproject.org:

Open haskell-devel package reviews which are split into

• New unassigned reviews (bit.ly/fedora-haskell-new-reviews2)
• Ongoing assigned reviews
  • Assigned reviews
  • Approved open reviews (fedora-review+)
• NotReady stalled reviews

)

Bugs

Non-review bugs can be split into:

• All open URM bugs (saved as haskell-available)
  • Untriaged URM bugs (saved as haskell-available:untriaged)
  • Triaged no missing deps (saved as haskell-available:ok)
  • Triaged missing deps (saved as haskell-available:deps)
• Package bugs
• Tracker for libraries with no revdeps
• ghc bugs not CC haskell-sig

All open Haskell bugs
