Haskell Horizon Platform
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.
