Nix Flake Support

This configuration is available as a Nix flake for easy installation on NixOS and other Nix-based systems.

Using the Flake

On NixOS

Add to your flake.nix inputs:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    neovim-config.url = "github:kennethdsheridan/nvim";
  };
  
  outputs = { self, nixpkgs, neovim-config }: {
    nixosConfigurations.your-hostname = nixpkgs.lib.nixosSystem {
      # ... your config
      modules = [
        {
          environment.systemPackages = [
            neovim-config.packages.${system}.default
          ];
        }
      ];
    };
  };
}

Direct Usage

# Run Neovim with this config
nix run github:kennethdsheridan/nvim

# Enter development shell with all tools
nix develop github:kennethdsheridan/nvim

# Install locally
nix profile install github:kennethdsheridan/nvim

Home Manager

{
  inputs.neovim-config.url = "github:kennethdsheridan/nvim";
  
  # In your home.nix
  home.packages = [
    inputs.neovim-config.packages.${pkgs.system}.default
  ];
}

Development Shell

The flake provides a development shell with all necessary tools:

• Language servers (lua-language-server, rust-analyzer, nil, nixd, etc.)
• Formatters (stylua, nixpkgs-fmt, rustfmt, prettier, black)
• Utilities (ripgrep, fd, fzf, lazygit)

Local Development

# Clone and enter development environment
git clone https://github.com/kennethdsheridan/nvim ~/.config/nvim
cd ~/.config/nvim
nix develop

# Or with direnv (if .envrc is present)
direnv allow
