Installation ​

We have a few different ways to install crush. The easiest is to use your package manager:

bash
# Homebrew
brew install charmbracelet/tap/crush

# NPM
npm install -g @charmland/crush

# Arch Linux (btw)
yay -S crush-bin

# Nix
nix run github:numtide/nix-ai-tools#crush

# FreeBSD
pkg install crush

Windows users:

bash
# Winget
winget install charmbracelet.crush

# Scoop
scoop bucket add charm https://github.com/charmbracelet/scoop-bucket.git
scoop install crush

Nix ​

Crush is available via the official Charm NUR in nur.repos.charmbracelet.crush, which is the most up-to-date way to get Crush in Nix.

You can also try out Crush via the NUR with nix-shell:

bash
# Add the NUR channel.
nix-channel --add https://github.com/nix-community/NUR/archive/main.tar.gz nur
nix-channel --update

# Get Crush in a Nix shell.
nix-shell -p '(import <nur> { pkgs = import <nixpkgs> {}; }).repos.charmbracelet.crush'

NixOS & Home Manager Module Usage via NUR ​

Crush provides NixOS and Home Manager modules via NUR. You can use these modules directly in your flake by importing them from NUR. Since it auto detects whether its a home manager or nixos context you can use the import the exact same way 😃

nix
{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    nur.url = "github:nix-community/NUR";
  };

  outputs = { self, nixpkgs, nur, ... }: {
    nixosConfigurations.your-hostname = nixpkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        nur.modules.nixos.default
        nur.repos.charmbracelet.modules.crush
        {
          programs.crush = {
            enable = true;
            settings = {
              providers = {
                openai = {
                  id = "openai";
                  name = "OpenAI";
                  base_url = "https://api.openai.com/v1";
                  type = "openai";
                  api_key = "sk-fake123456789abcdef...";
                  models = [
                    {
                      id = "gpt-4";
                      name = "GPT-4";
                    }
                  ];
                };
              };
              lsp = {
                go = { command = "gopls"; enabled = true; };
                nix = { command = "nil"; enabled = true; };
              };
              options = {
                context_paths = [ "/etc/nixos/configuration.nix" ];
                tui = { compact_mode = true; };
                debug = false;
              };
            };
          };
        }
      ];
    };
  };
}
