Nix metals

Expose metals as a nix derivation

Usage

Add to your inputs:

nix-metals = {
  url = "github:ghostbuster91/nix-metals/stable";
  inputs.nixpkgs.follows = "nixpkgs";
};

(or use nightly branch if you would like to use snapshot versions)

Configure your editor to use provided metals package.

Example for neovim:

metals_config.settings = {
    metalsBinaryPath = binaries.metals_binary_path,
    showImplicitArguments = true,
    superMethodLensesEnabled = false,
    excludedPackages = {
        "akka.actor.typed.javadsl",
        "com.github.swagger.akka.javadsl",
    },
    enableSemanticHighlighting = false,
}

where metals_binary_path is set to:

"${nix-metals.packages.${system}.metals}/bin/metals",
