nixos VS nixpkgs-config

I don't know. Have been using colorbuddy for ages now and it has always done exactly what I want. I don't need the "instant reaload" that lush advertices, doing :source on the colorscheme file, does the same for me to preview changes instantly. This is my theme, in case you need something to start with: - https://github.com/pinpox/nixos/blob/main/home-manager/modules/nvim/lua/config/pinpox-colors.lua

I use this to serve a directory temporarily.

I can't remember why I put that workaround in there, might not be needed any more. The above config is part of my dotfiles, I use my Bose blueutooth headphones by connecting them via the blueman-applet if the don't pair automatically

Here is an example from my config : I'm using an external flake called "matrix-hook", which is a little tool I wrote and have put in a separate flake. It get's included here. I am then passing self to each of the nixosConfigurations here, this allows me to import the module from the external flake in the configuration.nix of the host where I want to use it.

Yep, I have two different modules with defaults for server and for desktop. Host-specific settings are set in the according /machines//configuration.nix file. Most stuff is modularized into modules that can be reuesed and enabled at will.

Yep, I'm using the toJSON function already. The problem I had, was that not all applications use JSON as configuration format. Also the nix code gets very long, if you have to write the whole template as a string, which I find quite unreadable. Mustache is a pretty simple frequently used templating language, here is an example template that get's rendered by the nix code above.

My system uses a uniform colorscheme defined here. Configs for all applications I use read that and use the same colors. The wallpapers are randomly generated by a tool I wrote, it also automatically matches the colorscheme. Icons and symbols are colored the same way for awesomeWM.

In case you are interested I use this and this to generate colorschemes, awesome config and a matching wallpaper

Check out wezterm it has replaced tmux for me. Very active development, fast and just the right amount of features for my taste. It is configured in Lua, so if you are doing that for neovim already, it's another plus. I use it in combination with awesomeWM. My (not very special) config is here if you need something to start with.

You can also take a look at my server configuration which uses flakes. And my separately-managed home-manager configuration which also uses flakes

My "rice": https://github.com/jonringer/nixpkgs-config

I configure my neovim through home-manager. My configuration. Pulling vimPlugins from nixpkgs should give you something which works with NixOS (or anywhere for that matter, NixOS is essentially a clean room).

My dot file repo.

Home-manager link My example setup

Reference: - home.nix entry - Which refers to it's own dedicated file

If you want to take nix for a spin, i would recommend trying home-manager. It's essentially NixOS, but for dot files. It can install packages and services in addition to manage configuration. Also, I've been able to get it work on NixOS, WSL2, ubuntu, and macOS. Personal configuration if you're curious how it would look.

> And about Home Manager, the reason why I think it's over-hyped is because it provides a declarative approach to something that was... already declarative. Your $XDG_CONFIG directory does not need a leaky Nix abstraction on top of it

I don't really agree, I spent about 30mins to get my home-manager config to support an m1 mac [0]. I don't really want to think how long it would take me to look up all of the homebrew package names, and learn a new package manager. Instead, I just pushed all of the linux-specific items into their own bin, a little more logic, and I was able to get back to a comfortable terminal + git + vim settings.

Also, nix exposes congruent configuration management[1]. The state of my system is an exact reflection of the configuration. With other tools like ansible, vagrant, etc, I would get reconciliation configuration which is close on initial install but configuration drift is an ever-present concern; not to mention that large recipes and playbooks can take a very long time to run. Going the homebrew route would be divergent configuration, it would be very hard for me to get back to a certain configuration. With nix (and by extension home-manager), I can version control the configuration, improve it, roll it back, w/e I want.

> Why would I write my i3 config in Nix??

You do get some type checking, although the iteration time would probably be similar. You could also just do `xsession.windowManager.i3.extraConfig = builtins.readFile ./i3.config;` if you really just wanted to wholesale read in your existing profile.

> I'd rather just use `nix-env` personally.

nix-env is a double edge sword. You can rollback (somewhat, I believe it's just a stack of all changes), which is an improvement. However, nix only retains the "derivation name" to try and management. But for packages like python38, if you try to upgrade it, it will determine that `python-3.11-a3` is the package which is the most up-to-date. I try to discourage using nix-env.
