Nix installation?

[spacekitteh]

Anyone have a nix expression to install this?

When I have spare time, I try to keep up with the master branch for GHC 8.6.5 here: https://github.com/korayal/hls-nix It also has a cachix cache for darwin & linux

@korayal I tried out a bunch of different derivations I found floating around.
Yours is the only one that worked out of the box.
If you're happy to maintain this, it would be great to add a link to hls-nix from the haskell-language-server readme. Might prevent a few other people from waiting for GHC builds.

Would anyone like to update the README to reflect this?

@414owen I don't think my version is useful for everyone using nix, because the build is only confirmed on the fixed nixpkgs version I'm using on GHC 8.6.5. The nix expression could be useful for people trying this out on their own versions. I don't plan on maintaining this on any other combinations than what I use at the time. Even 'that' takes ~0-2 hours of my time depending on the change in dependencies.

It would be nice to build a hls clone for all-hies (or ghcide-nix) though. But unfortunately, I do not have the time to do that. but if someone does, I can support and contribute to that effort when I have the spare time.

@korayal fair enough. I might look into supporting more GHC versions and setting up CI.
Thanks for bootstrapping a build :)

Is it ok if I work on this? I am learning Nix packaging and try to build hls on Nix too.

@414owen thanks! Btw, I did kick off a clone of ghcide-nix on a branch here for hls-nix and started a build for hls-ghc865. it could take hours, so I don't know if it will succeed on first try. but I think if we can make it build and push to a cache, it would be pretty easy to maintain. Maybe @domenkozar can help us out here.

@zypeh this can also be useful if you wanted to take on this challenge.

Would you be up to having Nix expressions in this repo? That would really make things easy.
