Add FUTO.MDNS Flake

[danthony28]

I've written and tested a flake.nix for FUTO.MDNS

It appears to build FUTO.MDNS as Grayjay.ClientServer expects, but I can't be sure until I test it on Grayjay.Desktop/Grayjay.ClientServer/flake.nix. If someone with more knowledge of dotnet's intricacies (and .csproj files in partilcular, namely Grayjay.ClientServer.csproj) could verify this, I would appreciate it very much.

You can replicate this build to your own satisfaction by running nix build from the repo's root or running nix build github:danthony28/FUTO.MDNS/flake-futo-mdns from pretty much anywhere and digging through the result symlink. My intentions are to use this derivation as-is in the way dotnet build, dotnet publish, etc. expect in the flake.nix for Grayjay.ClientServer; ideally straight from nixpkgs but it's just a flake for now.

I'll commit the lockfile once everything is verified to be working as dotnet expects on Grayjay.ClientServer (not just as I expect).

Note

To the maintainers

I'll be following the "branch stacking" convention for these flakes, so it may be more convenient to merge a different branch, which should be mentioned below. I'll do my best to specifically comment when a branch shouldn't be merged into master (this is usually because it will cause messy conflicts down the road).

• This particular branch must be merged for https://github.com/danthony28/Grayjay.Desktop/tree/flake-grayjay-clientserver to be merged.
• This branch cannot be merged until that same branch has a verified-working flake.nix
• This branch should have a lockfile committed before merging.

Warning

alejandra.toml support is experimental!

Alejandra, my formatter of choice, only added support for alejandra.toml in v3.1.0. All branches of nixpkgs are up-to-date (i.e., package v3.1.0 of alejandra) but your system's software repository may differ. You can run alejandra --version to be sure.
