Horizon Haskell - Haskell Package Publishing

Version 0.14.0 of the dhall horizon-spec is out. store.horizon-haskell.net View the ChangeLog here: gitlab.horizon-haskell.net/dhall/horizon-…

Just released `ghc-common-hadrian-0.4.0`. This is a flake-parts module that can use the nixpkgs-provided `common-hadrian.nix` function to build GHC versions from 9.4 onwards just using module options. gitlab.horizon-haskell.net/nix/ghc-common…

Just upgraded from a 50GB @cachix_org to 250GB due to cache misses on older compilers! Hope it's enough space now!

Horizon Haskell now has markdown reports of supplied package sets for each GHC version. horizon-haskell.net/Package%20Sets…

@SeungheonO It's back up now.

@horizonhaskell horizon-haskell.net is down

Horizon Haskell combines the stability of stack with the reproducibility of nix

Horizon now has a GHC 9.12 template you can try from the QuickStart page. horizon-haskell.net/QuickStart.html

@horizonhaskell is looking for sponsors for GHC 9.12 compatibility support. We were able to get 500 packages compatible with GHC 9.10 on the day of release. This time we aim to make it 1000. We are looking for a small sponsorship from a Haskell company to pay for expenses.

There is now a template for horizon-cardano on the QuickStart guide. horizon-haskell.net/QuickStart.html

Here is an interesting error from polysemy. Caused by -Woverlapping-patterns.

Everything in horizon-core was more of the same template-haskell change. On to the next package set, horizon-advance.

Starting GHC 9.10 Compatibility Work on three architectures: x86_64-linux, aarch64-darwin, aarch64-linux. Documenting what we find in this thread. 🧵

@TeofilC I took a few patches from head.hackage for some of the remaining libraries and listed the attribution in the LICENSE file. Feel free to copy some of the ones not yet in head.hackage if needed.

@horizonhaskell This sounds quite similar to head.hackage. Perhaps you'd be up for collaborating? Eg, this bifunctors patch is already there

Horizon supports upgrade paths from GHC 8.10 all the way through to mainline.

@horizonhaskell is really nice for doing haskell things. I needed to scaffold a project and get some code out and it just works.

Just merged plutus 1.21 to horizon-plutus. gitlab.horizon-haskell.net/package-sets/h…

Huge improvements to the Horizon CI today. Everything is running in a much tighter feedback loop.

500 packages ready for GHC 9.10. gitlab.horizon-haskell.net/package-sets/h…
