# This file is an alternative to shell.nix that uses haskell.nix | ||

# | ||
# To run the shell from this file run: | ||
# | ||
# nix-shell haskell.nix -A shell | ||
# | ||
# Significant differences to shell.nix: | ||
# | ||
# * It uses the `nixpkgs-unstable` pin of nixpkgs from haskell.nix | ||
# instead of the niv pin (this will increase the chances of getting | ||
# a cache hit when using the haskell.nix binary cache). | ||
# | ||
# * Haskell.nix reads the `source-repository-package` config from | ||
# the `cabal.project` and other info from `plan.json`. This means | ||
# it does not depend on `nix/default.nix` and there is no list | ||
# of the projects packages in this file to update. | ||

# Maintaining this file | ||

# * Bump the haskell.nix version using `niv update haskell.nix`. | ||
# This will update the hackage snapshot used to build the | ||
# dependencies of the project and any `tools` set to `latest` below | ||
# will be updated to the latest version in that snapshot. | ||

The
haskell-language-server
Cachix account is limited to 5GB, so this won't work. I recommend using a different Cachix account for the haskell.nix artifacts, I can set up the token if you share it via email ([email protected]).To test it, you will have to open the PR from a GitHub.com/haskell/haskell-language-server branch, otherwise the GitHub action cannot see the token.

Sorry, I just saw this. Do you still need me to do this?
I tried pushing the hkm/haskell-nix branch to haskell/haskell-language-server, but got:
It used quite a lot of github minutes building GHC. Is it possible (and would it make sense) to use the IOHK cache instead of cachix (or better yet as an upstream cache if that is possible)?

Github says that it is awaiting your response:

It makes sense to use the IOHK cache, as long as it freely accessible and also provides Mac OS builds?
