The purpose of this script is
|
||||
|
||||
1) download the state of the nixpkgs/haskell-updates job from hydra (with get-report)
|
||||
2) print a summary of the state suitable for pasting into a github comment (with ping-maintainers)
|
||||
3) print a list of broken packages suitable for pasting into configuration-hackage2nix.yaml
|
||||
|
||||
Because step 1) is very expensive and takes roughly ~30 minutes the result is cached in a json file in XDG_CACHE.
