Usage: $self [options]

Options:

   --do-commit    Commit changes to this file.

   -f | --fast    Do not update the transitive-broken.yaml file.

   -h | --help    Show this help.

This script is used to regenerate nixpkgs' Haskell package set, using the

tool hackage2nix from the nixos/cabal2nix repo. hackage2nix looks at the

config files in pkgs/development/haskell-modules/configuration-hackage2nix

and generates a Nix expression for package version specified there, using the

Cabal files from the Hackage database (available under all-cabal-hashes) and

its companion tool cabal2nix.

Unless --fast is used, it will then use the generated nix expression by

running regenerate-transitive-broken-packages.sh which updates the transitive-broken.yaml

file. Then it re-runs hackage2nix.

Related scripts are update-hackage.sh, for updating the snapshot of the

Hackage database used by hackage2nix, and update-cabal2nix-unstable.sh,

for updating the version of hackage2nix used to perform this task.

Note that this script doesn't gcroot anything, so it may be broken by an

unfortunately timed nix-store --gc.
