- Switch to the haskell-updates branch, so that we get Stackage nightly packages
- Remove the hard-coded list of packages, let cabal2nix find out
- A Github Action to exercise the Nix script and warm up a Cachix cache

I think this one would close #122, as we would have an "official" way to install using nix. |

What do you guys think about adding nixfmt to shell.nix packages and use it on all Nix files? This solves all formatting concerns.
This may also help, as e.g. here the let .. in .. was not aligned and I had slight trouble understanding 😅

The Cabal part is unrelated to Nix, as one can use Nix with Stack. How about removing the 2 Cabal commands?

This Nix script is specifically targeted at using with cabal build
The haskell-updates branch is already on Stackage nightly, which allows for a much better cache hit rate (assuming haskell-updates is backed by a Hydra cache, which I'm not quite sure of).
Adds support for auth tokens
Did you try to setup the Cachix binary cache? It should have downloaded all the artefacts for you (and stack will happily ignore them, but at least you don't have to wait for Nix) |
