Usage

You will probably want to see our Getting started guide, but as a TLDR:

1. Import the NixOS and home-manager modules

With Flakes

{
  inputs = {
    nixpkgs.url = "nixpkgs/nixos-unstable";
    catppuccin.url = "github:catppuccin/nix";
    home-manager = {
      url = "github:nix-community/home-manager";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { nixpkgs, catppuccin, home-manager }: {
    # for nixos module home-manager installations
    nixosConfigurations.pepperjacksComputer = pkgs.lib.nixosSystem {
      system = "x86_64-linux";
      modules = [
        catppuccin.nixosModules.catppuccin
        # if you use home-manager
        home-manager.nixosModules.home-manager

        {
          # if you use home-manager
          home-manager.users.pepperjack = {
            imports = [
              ./home.nix
              catppuccin.homeManagerModules.catppuccin
            ];
          };
        }
      ];
    };

    # for standalone home-manager installations
    homeConfigurations.pepperjack = home-manager.lib.homeManagerConfiguration {
      pkgs = nixpkgs.legacyPackages.x86_64-linux;
      modules = [
        ./home.nix
        catppuccin.homeManagerModules.catppuccin
      ];
    };
  };
}

With Nix Channels

sudo nix-channel --add https://github.com/nix-community/home-manager/archive/master.tar.gz home-manager
sudo nix-channel --add https://github.com/catppuccin/nix/archive/main.tar.gz catppuccin
sudo nix-channel --update

For NixOS module installations:

{
  imports = [
    <catppuccin/modules/nixos>
    # if you use home-manager
    <home-manager/nixos>
  ];

  # if you use home-manager
  home-manager.users.pepperjack = {
    imports = [
      <catppuccin/modules/home-manager>
    ];
  };
}

For standalone installations

{
  imports = [
    <catppuccin/modules/home-manager>
  ];

  home.username = "pepperjack";
  programs.home-manager.enable = true;
}

2. Choose your desired flavor with catppuccin.flavor

{
  catppuccin.flavor = "mocha";
}

3. Enable for supported programs with catppucin.enable = true;

{
  programs.starship = {
    enable = true;
    catppuccin.enable = true;
  };
}

4. Enable for all available programs you're using!

{
  catppuccin.enable = true;
}

🙋 FAQ

• Q: "How do I know what programs are supported?"
  A: You can find programs supported through home-manager here, and NixOS modules here

• Q: "How do I set catppuccin.enable for everything I use?"
  A: You can set catppuccin.enable globally

• Q: "What versions of NixOS and home-manager are supported?"
  A: We primarily support the unstable branch, but try our best to support the current stable release. You can check if your stable release is currently supported at status.nixos.org

nix's Issues

yazi: theme installs but no synatx highlighting

The yazi theme decalres the synax highligting to ~/.config/yazi/theme.tmTheme
see https://github.com/catppuccin/yazi/blob/0846aed69b2a62d29c98e100af0cf55ca729723d/themes/mocha.toml#L32

But the flake does not provide that file, this could be solved by useing the bat themes' .tmTheme file.

home-manager.users.usn.gtk.catppuccin.flavor' does not exist

I have catppuccin nix included in nix inputs, and inputs being inherited .

{inputs, ...}: {
  imports = [inputs.catppuccin.homeManagerModules.catppuccin];
  xdg.enable = true;
  gtk = {
    enable = true;
    catppuccin = {
      enable = true;
      flavor = "mocha";
      #accent = "pink";
      #size = "standard";
      #tweaks = [ "normal" ];
    };
  };
}

result home-manager.users.usn.gtk.catppuccin.flavor' does not exist

Publish to flake registries

once we make an actual stable release with #65, this would be useful for those wanting to avoid any breaking changes. https://flakestry.dev/ is my main choice here, but https://flakehub.com/ could be used alongside it

Testing

I'd like to test the output of this module with various configurations, we can probably use some kind of expectation testing.

I'll work on this.

Support Nix Darwin

Would it be something possible to add a module to support nix-darwin system configurations ?

Trying to use catppuccin-nix in a darwin module cause this error (grub isn't a thing in nix-darwin):

error: The option `boot.loader.grub.font' does not exist. Definition values:
       - In `<unknown-file>':
           {
             _type = "if";
             condition = false;
             content = "/nix/store/9dgvl02bvzsadmwsq014r14509bf6fmz-catppuccin-grub-theme/font.pf2";
           }

Use themes from the cattpuccin package?

Nixpkgs has a catppuccin package that has some of the themes this module can set, so it might be a good idea to use it if possible

bat theme not work

bat give me this warning:

[bat warning]: Unknown theme 'Catppuccin-mocha', using default.

split cursors into separate module

as it is now, i have to apply them twice to get them working with all apps like this

SDDM Themeing broke

All i can say for sure is that before the renaming of "flavour" to "flavor" the themeing worked, and after i saw the error being caused by the rename and fixed them, then upgraded it no longer was themed. It looks like the default SDDM Theme, so not the Plasma6 theme or anything, just the default default one.

I will attach a screenshot below, just need to figure out how to do that part.

fix some colours... foot

so i tried your thing in foot and when i ran htop i can't see many text can change colour or anything that can increase the readability of text i tried catppuccin mocha...

(theme name is taribble..)

package options

It would be nice to be allowed to change the package for gtk, as an example. Since its hardcoded see

nix/modules/home-manager/gtk.nix

Line 57 in 57e8376

package = pkgs.catppuccin-gtk.override {

How to follow updates?

I love the project! I find myself coming back about every week to see what's new. Is there a better way? Perhaps a community were announcements are done? If not perhaps releasing a changelog and people can sign up to watch? Thanks!

GTK cursors in GNOME don't enable properly

I am using the gtk home-manager module with the following snippet:

gtk = {
  enable = true;
  catppuccin = {
    enable = true;
    cursor.enable = true;
  };
};

When I rebuild my system, only some of the cursors change and there's just a white square when the cursor is on the desktop. When I manually activate the cursor theme from the gnome-tweaks GUI they work perfectly.

Using dconf, it seems that gnome-tweaks expects a cursor theme named "Catppuccin-${flavour}-${accent}-Cursors" whereas the gtk home-manager module names the cursor theme "Catppuccin-${flavour}-${accent}". I have tested renaming this in a fork and it seems to work fine, but I'm not sure if it breaks in another context.

Why option `xdg.enable` is required?

I've added this module to my home-manager config and I've got Option xdg.enable must be enabled to apply Catppuccin theming error. I wonder why is this option required? What this option does is adding environment variables and allows to change directories for it. But if this option is not enabled, then default directories are used and no environment variables are set. All programs are expected to use default directories if there is no env vars. A specifically didn't enable xdg to not create extra env variables and it all works well. I think this module should not require to set xdg.enable. Am I missing something?

Unreferenced Cursor File Is Stuck In Nix Store

So, I've noticed that the cursor files for the Mocha-Blue cursors are stuck in the store. I've run sudo nix-collect-garbage -d a number of times and the files remain in the store. I've searched through my entire config, and the only place I'm referencing is in my home-manager config, in this file: theme.nix

What follows is a nix-store --query call that shows that the Mocha-Blue cursor files are still in the store.

[root@LATITUDE-NIXOS:/etc/nixos]# nix-store --query --referrers-closure /nix/store/qz1lqp3lqxwby21ggqh3dc2ck6bh2kyp-catppuccin-cursors-0.2.0-mochaBlue

Documentation

I would like to have a site similar to https://rycee.gitlab.io/home-manager/options.html that describes available configuration options.

GTK themes are not applied correctly

I have the following home-manager GTK config:

  catppuccin.flavour = "mocha";

  ...

  gtk = {
    enable = true;
    catppuccin = {
      enable = true;
      size = "compact";
      accent = "pink";
      tweaks = [ "rimless" ];
      cursor = {
        enable = true;
        accent = "dark";
      };
    };
  };

When I switch to this config using home-manager switch --flake, all the GTK apps have the white background. I have tried different revisions of catppuccin/nix flake and figured out that 1fbdfdacf96c14449aea52edba895e5ab419dd13 seems to be the culprit.

Example GTK app before 1fbdfdac:

After:

Waybar support.

Can you add waybar theme support?

Feature request: gtk cursor: be able to set the size

On my laptop with sway, I usually need to increase the size of the cursor.

I use this right now:

{
  home.pointerCursor = {
    package = pkgs.bibata-cursors;
    name = "Bibata-Modern-Ice";
    size = 22;
  };
}

My screen resolution is: 3200x1800

Tbh, I don't know if setting the cursor size is the right way to fix it or not.

System-wide accent option

Hi, thanks for your works!

Currently, there is no accent option on nixos-modules and I know it is not necessary. However it helps to unify theme. Here is some examples.

# configuration.nix
catppuccin = {
  flavour = "mocha";
  accent = "teal";
};

# To pass custom icon to flatpak, you have to install it globally.
environment.systemPackages = with pkgs; [
  (catppuccin-papirus-folders.override {
    flavor = "${config.catppuccin.flavour}";
    accent = "${config.catppuccin.accent}";
  })
];

# home.nix
# You cannot use this on standalone home-manager setup.
{ osConfig, ... }:

{
    catppuccin = { 
      flavour = "${osConfig.catppuccin.flavour}"; 
      accent = "${osConfig.catppuccin.accent}";
    };
}

GTK theme error: 'border-spacing` is not a valid property name

So, I was looking at journalctl output in order to resolve a completely different problem, and noticed a log message saying Theme parsing error: gtk.css:7763:16: 'border-spacing' is not a valid property name. Turns out that, if I run any GTK app from the terminal, I get the same error message printed to the terminal.

After doing some testing, I have found that this issue only occurs when the Home-Manager module option gtk.catppuccin.enable is set to true.

Move to nixfmt

see NixOS/rfcs#166. once there is a stable release, we should probably switch to it in order to conform to the wider community

Use with hyprland-nix

Is there a way I can use this with hyprland-nix: https://github.com/hyprland-community/hyprland-nix. Which doesn't have the same options as the home-manager one.

Currently I get the following error:

    error: The option `wayland.windowManager.hyprland.settings' does not exist. Definition values:
       - In `<unknown-file>':
           {
             _type = "if";
             condition = false;
             content = {
               "\$base" = "rgb(1e1e2e)";

Because there is not settings field when using that flake. Is there a way to ignore the hyprland module in this flake? Probably more of a general question. I haven't tried to enable catppuccin in hyprland btw.

Thanks

Rofi support forces a default option for font that might not work with all users

The rofi themes provided by a recent commit seem to just use the default theme configs from https://github.com/catppuccin/rofi/tree/main/basic/.local/share/rofi/themes

The main issue with this is these 4 themes all have the same line 12: font: "JetBrainsMono Nerd Font 14"; This font isn't installed on my machine, and the options provided here don't give me any ways to change this. I'd prefer this to either install the required fonts for me, or give me a way to change the font myself.

Support NixOS & home-manager's stable branches

i.e., 23.11, 24.05. for now we target and test against nixos-unstable and the master branch of home-manager

recommendations on how to approach this are welcome :)

Port request: tty

Port: catppuccin/tty
Example: https://git.sr.ht/~stonks3141/nixos-config/tree/main/item/modules/system.nix#L49

We'll have to bring in catppuccin/palette to get the hex codes.

Port request: foot

Port: https://github.com/catppuccin/foot
Example: https://git.sr.ht/~stonks3141/nixos-config/tree/main/item/modules/applications/foot.nix

wrong repo url in readme

links in readme is catppuccin/nix, but it should be Stonks3141/ctp-nix?

Bug: bat themes are now a set

System does not build with catppuccin nix, "tofi.settings" does not exist

Releases

Hey, thank you for this!

I was wondering how I could get notified of new modules (however infrequently that may occur).

So I was thinking releases. Just a thought.

Enabling Hyprland setting overwrites configuration

Setting wayland.windowManager.hyprland.catppuccin.enable = true causes this module to overwrite every option declared in wayland.windowManager.hyprland.settings except for the Catppuccin colors. This will most likely leave anyone with a config with no keybinds, etc., unless they use the extraConfig option (not tested, I'm just guessing). With the introduction of wayland.windowManager.hyprland.sourceFirst, I'm guessing the source order issues described in /modules/home-manager/hyprland.nix are no longer present and that this module can use source as normal.

Port Request: waybar

https://github.com/catppuccin/waybar

Are global color overrides possible?

It looks like this is just downloading the respective config files from the other catpuccin repos, but I'm wondering if it would be possible to do global color overrides?

For example if I wanted a darker background color, it would be nice to be able to do that globally like

catppuccin = {
  enable = true;
  flavor = "mocha";
  color_overrides = {
    mocha = {
      base = "#[some other color code]";
    };
  };
};

Expose `lib.ctp` to `config.lib.ctp`

I'm working on exposing lib to config instead of extending nixpkgs' lib so that users can have access to some useful functions like mkUpper

@getchoo are you open to this?

Port Request: Rofi

Rofi themes exist here: https://github.com/catppuccin/rofi
There are a ton of home-manager options that you can play with that should make this easier to do: https://nix-community.github.io/home-manager/options.xhtml#opt-programs.rofi.enable

Honestly, I'd be fine with just basic support if adding support for the Deathemonic version at the same time proves to be infeasible for some reason.

GTK: link GTK 4.0 to correct places

In https://github.com/catppuccin/gtk it suggests that you link gtk 4.0 to given places. See the snippit below

xdg.configFile = {
  "gtk-4.0/assets".source = "${config.gtk.theme.package}/share/themes/${config.gtk.theme.name}/gtk-4.0/assets";
  "gtk-4.0/gtk.css".source = "${config.gtk.theme.package}/share/themes/${config.gtk.theme.name}/gtk-4.0/gtk.css";
  "gtk-4.0/gtk-dark.css".source = "${config.gtk.theme.package}/share/themes/${config.gtk.theme.name}/gtk-4.0/gtk-dark.css";
};

Port Request: qt(kde) theme

https://github.com/catppuccin/kde

Create a docs website

While the current markdown files updated by CI work...it's not great. Ideally we should have a site for these options, like search.nixos.org or the home-manager manual. Having a way to search for options would also be welcome

i plan on implementing this using nixosOptionDoc and mkdocs

Add global `enableAll` setting

Hi,

I'd love to just add this flake to my inputs and use a global toggle to enable the theming on all programs I've installed.
This would've the benefit of not having to check on the progress of the program options now and then and to automatically get satisfied when there is a new program supported :)

What do you think?

PS: Thanks for your work!

expose palette to lib

to allow usage for applications/modules that don't yet have a port

Link palette files to graphics editors

I've written https://github.com/uncenter/flake/blob/main/home/apps/inkscape.nix to solve this issue in my personal flake. It downloads the latest release assets from catppuccin/palette and moves the gimp/ directory to the palettes/ directory of Inkscape. I'm not sure what the other configuration locations are for the other graphics programs the release assets support.

Document modules that need Allow From Derivation

An extra readme segment that specifies which modules require Allow From Derivation
or/and an option to exclude those modules from the global enable option.

Previews

What should the previews show?

formatting/general code style guidelines

we've talked about this a lot, so i think it might be a good time to actually figure out what formatter we're going to use, and what (if any) code style guidelines we would want to put in CONTRIBUTING.md. a good example of how we could approach this is found here in the home-manager manual

Add Dunst Support

I don't think this should be too hard. You already have Dunst themes here:
https://github.com/catppuccin/dunst/tree/main

For Home-Manager integration, you use one of these two options:
