Horizon Haskell: Hydra
horizon-hydra is a Package Set targetting hydra and all dependencies required to interact with it.
Package Set Policy
This package set has the following policy.
- GHC will advance as often as possible.
- Non-versioned locations (git, unversioned tarballs) are permitted to allow GHC to advance.
- The following packages must always build:
- cardano-api
- cardano-cli
- cardano-node
- hydra-node
Updating the Package Set
Generating the nix expressions for the package set is a two step process.
-
Edit the
horizon.dhall
file. -
Run
nix run develop/#horizon-gen-nix
You can edit the horizon.dhall
file in one of two ways: manually using a text
editor, or programatically using horizon-shell
.
Tweaking & Hacking
If you need to do additional manual overrides to the nix code, such as
addPkgconfigDepends
, edit the configuration.nix
overlay, which is
applied over the generated derivations.
If you need to nullify libraries, use the configuration/hacking.nix
overlay.
Try to leave a note as to why this library has been nullified.
Feedback
To build all packages, run
nix run develop/#feedback -- build
Hoogle
To run a hoogle server containing the entire package set. Do
