crate2nix VS nixos

I'll use nixpkgs' buildRustPackage. There's a few other tools, my favorite being crate2nix, but we'll leave that to a future tutorial.

If you want to iterate with nix instead of cargo, crate2nix and cargo2nix provides more caching and more fine control over your dependencies. I haven't used these two so you would have to decide for yourself. You may also want to try out nocargo for something more experimental.

I'm yet to try it out, but from the blog post, the README and the source it appears that Crane builds all dependencies in one derivation (separately from the main crate). This means that if a dependency gets added, removed or changed, all dependencies of a crate will be rebuilt. This is in contrast with https://github.com/kolloch/crate2nix, which does build every dependency in a separate package, thus you don't need to rebuild other dependencies if you only change a small part of the tree.

Yes, you will have to package it if it's not already in nixpkgs.

The good news is once you learn how, it's basically trivial with crate2nix[0], which can autogenerate nix derivations from rust crates

From my quick reading of cargo2nix's webpage yes. https://github.com/kolloch/crate2nix has a workspaces section.

As for your two applications, they're both written in Rust, and I like https://github.com/kolloch/crate2nix as a way to package Rust crates with Nix. BTW, wezterm is already in nixpkgs!

I like the way crate2nix works. I have made a flake template for it here. Sometimes it requires a couple of overrides to fix some misbehaving crates (see https://github.com/balsoft/simple-osd-daemons/blob/master/flake.nix#L29 for an example of such overrides), but otherwise it's fantastic. It doesn't require any hash nonsense, it downloads and builds all the crates separately (unlike naersk or other solutions) so you get all the benefits of Nix (reproducibility and proper caching).

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.
