# Haskell Horizon Platform

[horizon-haskell.net](https://horizon-haskell.net).

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

## 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.
