I am unable to theme with Catppuccin or another theme

[Pierre-Thibault]

In nvim, I only have the default themes available. But, I have a setup with Catppuccin.

Here is my flake:

{
  description = "My NixOS's flake";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.11";
    nix-flatpak.url = "github:gmodena/nix-flatpak/?ref=latest";
    nvf.url = "github:notashelf/nvf"; # Neovim configuration
  };
  outputs =
    {
      nixpkgs,
      nix-flatpak,
      nvf,
      ...
    }:
    {
      nixosConfigurations.pierre-nixos = nixpkgs.lib.nixosSystem {
        system = "x86_64-linux";
        modules = [
          nix-flatpak.nixosModules.nix-flatpak
          nvf.nixosModules.default
          ./configuration.nix
        ];
      };
    };
}

And, here is my module:

{ ... }:

{
  programs.nvf = {
    enable = true;
    settings = {
      vim = {
        languages = {
          enableLSP = true;
          enableTreesitter = true;

          css.enable = true;
          gleam.enable = true;
          go.enable = true;
          html.enable = true;
          lua.enable = true;
          markdown.enable = true;
          nix.enable = true;
          python.enable = true;
          rust.enable = true;
          sql.enable = true;
          ts.enable = true; # This does Javascript too
          yaml.enable = true;
        };

        statusline.lualine.enable = true;
        telescope.enable = true;
        autocomplete.nvim-cmp.enable = true;

        theme = {
          enable = true;
          name = "catppuccin";
          style = "mocha";
          transparent = true;
        };
      };
    };
  };
}

What am I doing wrong?

Everything is fine. My terminal session was pointing an old PATH in the store. 😃
