❄️ My Personal Neovim Setup ❄️

My Nix-based Neovim configuration. For when you have an unhealthy obsession for declarativity and configurability.

Usage

Option 1: Clone and run

git clone https://github.com/fred-drake/neovim.git
nix run .#

Option 2: Run directly

nix run github:fred-drake/neovim#

Configurations

The default configuration performs editing without settings for any particular language or technology. The following configurations allow for CMP, LSP, Tree-Sitter and DAP in their respective language or technology stack:

• Rust nix run github:fred-drake/neovim#rust
• C# nix run github:fred-drake/neovim#csharp
• Go nix run github:fred-drake/neovim#golang
• Python nix run github:fred-drake/neovim#python
• Javascript nix run github:fred-drake/neovim#javascript
• Infrastructure as Code nix run github:fred-drake/neovim#iac

Install Multiple Configurations

You can have multiple neovim configurations (nvim, nvim-rust, nvim-golang, etc). Take a look at my system configuration flake to see how I do this, but here's the gist:

Create a function that creates neovim links with unique configuration names:

mkNeovimPackages = pkgs: neovimPkgs: let
    mkNeovimAlias = name: pkg:
    pkgs.runCommand "neovim-${name}" {} ''
        mkdir -p $out/bin
        ln -s ${pkg}/bin/nvim $out/bin/nvim-${name}
    '';

And add it to your home-manager imports:

({pkgs, ...}: {
    home.packages =
    (builtins.attrValues (mkNeovimPackages pkgs inputs.neovim.packages.${pkgs.system}))
    ++ [inputs.neovim.packages.${pkgs.system}.default];
})
