Haskell Horizon Platform

horizon-haskell.net.

Horizon is a haskell package set targetting new builds of GHC.

Getting started

You an can use this package set instead of your haskell packages set in nixpkgs. To see an example you can use the template supplied with this repository.

mkdir myProject
cd myProject
nix flake init -t 'git+https://gitlab.homotopic.tech/horizon/horizon-templates'

Updating the package set

The package set is generated from the horizon.dhall using the following command:

nix run .#horizon-gen-nix

This will generate both the packages folder and the package set file. If you want to regenerate a particular package in the packages folder, delete that file from the packages folder. To regenerate the entire package set from scratch, delete the packages folder.

If you need to do additional manual overrides to the nix code, such as addPkgconfigDepends, edit the configuration.nix overlay, which is applied afterwards.
