Do you even nix?

A simple zsh-theme to enhance nix power. This theme express his full potential if you often rely on Nix's features such as shells and flakes. That said, you can still enjoy it without Nix if you like.

Appearence

This is how the theme will look like:

• normally;
• when you enter a directory with a git repo. Note how the current git user is shown. This comes handy when you have multiple remote repository's accounts like me and you are tired of committing stuff under the wrong user 😤;
• when you have something to commit;
• when there's a flake.nix in the current directory;
• when there's a shell.nix in the current directory;
• when you enter a nix shell. This will activate when $IN_NIX_SHELL env variable is valued. As you can see there's also the shell name. You can assign the shell name to pkgs.mkShell.name if you like. If you don't it'll fall back to the default shell name nix-shell-env ("-env" is by default added by nix to the shell name).

Installation

The Nix way 🗿

1. Find where you defined zsh settings in your nix configuration files (could be either in your configuration.nix or in your home.nix if you're using home-manager). It will look something like this:

programs.zsh = {
  enable = true;
  plugins = [ ... ];
  ...
}

2. Add the following value into the programs.zsh.plugins square brackets:

{
  name = "do-you-even-nix";
  file = "do-you-even-nix.zsh-theme";
  src = pkgs.fetchFromGitHub {
    owner = "miche1e";
    repo = "do-you-even-nix";
    rev = "v1.0.0";
    sha256 = "yXQ0YoO+6vebxjzDoH96Jk3IsABs4jMG4ZU9RmLt9u4=";
  };
}

3. Apply the changes :)

With oh-my-zsh

If oh-my-zsh is handling your plugins and themes.

1. Download* the theme file in in oh-my-zsh theme's folder:

wget 'https://raw.githubusercontent.com/miche1e/do-you-even-nix/refs/heads/main/do-you-even-nix.zsh-theme' -O $ZSH/themes/do-you-even-nix.zsh-theme

*If you don't have wget, using curl or cloning the whole project with git and moving the file manually will do the same.

2. Open your ~/.zshrc file, look for the ZSH_THEME variable and set it as follows:

ZSH_THEME=do-you-even-nix

Manual installation (git clone)

1. Clone the repo:

git clone https://github.com/miche1e/do-you-even-nix.git ~/.zsh/plugins/do-you-even-nix

2. Source the theme file in your .zshrc:

echo 'if [[ -f "$HOME/.zsh/plugins/do-you-even-nix/do-you-even-nix.zsh-theme" ]]; then
  source "$HOME/.zsh/plugins/do-you-even-nix/do-you-even-nix.zsh-theme"
fi' >> ~/.zshrc

Personalization

do-you-even-nix have a bunch of variables where special chars and colors are defined. These variables, if not already set, fall back to a default value that you can look up in the theme's file. If you don't like how it looks you can override them to your preference in your ~/.zshrc before sourcing the theme's file.
