https://github.com/NixOS/cabal2nix/blob/v2.18.0/CHANGELOG.md
2.18.0 mostly brings bug fixes, especially the one fixing the unclear
error message if a cabal file was missing (which was forgotten in the
changelog). It is not technically a non-breaking change since the
Haskell API changed.
Since there shouldn't be any breakage for users and all known reverse
dependencies of cabal2nix have been broken for a while, the benefits
of backporting outweigh the risks.
Introduces a script that can be used to update the Nix expressions for
the Haskell package set. In service of that, also
- introduces cabal2nix-latest, which pins the hackage2nix version used
- changes all-cabal-hashes to use fetchFromGitHub
- adds update-hackage.sh & update-cabal2nix-latest.sh & update-stackage.sh maintainer scripts
In preparation of the upcoming 0.6.0 release I wanted to fix hls.
It introduces two new plugin packages, which are not on hackage yet.
I remove apply-refact overrides, because current apply-refact versions
are compatible with all ghcs we support, according to their changelog.
I override more of the hls dependencies globally on the whole package
set, to avoid a lot of duplicate compilations. And because @peti changed
my mind about this being a good practice.
hls now uses a released version of ghcide
We had a few "overrides" in configuration-common.nix that were really
extensions. They introduced packages that weren't in hackage-packages.nix.
The advantage of having a dedicated file for these packages is that we can still
place Nix-specific overrides to these packages in configuration-nix.nix. We
weren't able do this before because configuration-nix.nix extended only the
packages from hackage-packages.nix.
