But a few months ago, I switched completely to [NixOS](https://nixos.org/), and honestly, I love it. The idea of configuring everything on my system **declaratively**—just by writing code—is what really got me hooked. - -## Sway with Nix - -I use [Sway](https://github.com/swaywm/sway) as my window manager, and setting it up with Nix has been super easy. Instead of messing with dotfiles or installing things manually, I just describe what I want in a config file and let Nix handle it. - -## Neovim + NVF - -One of my favorite changes has been switching my Neovim setup to use [NVF](https://github.com/NotAShelf/nvf). It makes managing plugins and settings way easier. - -Here's a peek at my `nvf.nix` config: - -```nix -{ config, lib, pkgs, ... }: - -{ - programs.nvf = { - enable = true; - settings = { - vim = { - theme.enable = true; - theme.name = "gruvbox"; - - options = { - clipboard = "unnamedplus"; - tabstop = 2; - shiftwidth = 2; - expandtab = true; - autoindent = true; - mouse = "a"; - }; - - telescope.enable = true; - autocomplete.nvim-cmp.enable = true; - - autopairs.nvim-autopairs.enable = true; - - git.enable = true; - - lsp = { - enable = true; - formatOnSave = true; - lspkind.enable = true; - lspSignature.enable = true; - }; - - languages = { - enableTreesitter = true; - - nix.enable = true; - markdown.enable = true; - - clang.enable = true; - css.enable = true; - html.enable = true; - java.enable = true; - ts.enable = true; - go.enable = true; - lua.enable = true; - python.enable = true; - typst.enable = true; - }; - - formatter.conform-nvim.enable = true; - - visuals = { - nvim-web-devicons.enable = true; - }; - - snippets.luasnip.enable = true; - - binds = { - whichKey.enable = true; - cheatsheet.enable = true; - }; - - statusline.lualine.enable = true; - }; - }; - }; - }; -} -``` - -You can check out my full Nix configuration [here on GitHub](https://github.com/schererleander/nix). - -## Firefox, Configured by Code - -I even manage **Firefox** through Nix! From settings to extensions, everything is set up declaratively. It’s cool to see a browser this customizable through config files. - -## Using nix-darwin on macOS - -I’ve got a **MacBook Air**, and I’m using [nix-darwin](https://github.com/LnL7/nix-darwin) on it. It’s not quite as deep as NixOS, but I can still manage most of my tools and configs declaratively. Works great for development stuff. - -## VPS with nix-infect - -My VPS is running Nix too. I used [nix-infect](https://github.com/elitak/nix-infect) to get started, and now I manage things like **[nginx](https://nginx.org/)** and **[Nextcloud](https://nextcloud.com/)** with Nix. It’s super easy to maintain and back up. |
