# Darkmatter

A near-black GTK 3 / GTK 4 and xfwm4 theme, built from the [Darkmatter color scheme](https://github.com/stevedylandev/darkmatter-nvim).

>[!WARNING]
>This project is still a work in progress with minimal support for XFCE. Further support and ports can be requested in the issues, PR's welcome.

## Install

Prebuilt stylesheets are checked in, so no build step is required:

```sh
git clone https://github.com/stevedylandev/darkmatter-linux.git
cd darkmatter-linux
sh src/install.sh   # copies into ~/.themes/Darkmatter (+ -hdpi/-xhdpi variants)
```

Then select `Darkmatter` as your GTK theme and window manager theme, e.g.:

```sh
gsettings set org.gnome.desktop.interface gtk-theme Darkmatter   # GTK
xfwm4-tweaks-settings                                            # or via xfce4-appearance-settings / xfwm4-settings
```

`install.sh` only ships the GTK 3/4 stylesheets and xfwm4 decorations. Dunst and Rofi aren't app themes with a single install location, so copy them where each app looks for config:

```sh
cp dunst/dunstrc ~/.config/dunst/dunstrc
cp rofi/darkmatter.rasi ~/.config/rofi/darkmatter.rasi
```

**Icons are untouched.** `index.theme` still names Nordic's `Zafiro-icons`;
pick an icon theme and change that line.
