gnome-autotheme

Automatically generate theme for GNOME based on current wallpaper and preferred color theme.

Requirements

• Rust/Cargo installed
• ImageMagick (if you want to convert SVG or JXL wallpapers automatically)
• adw-gtk3(Optional) - install if you want to change GTK3 style as well
• Done

Installation

Just 3 simpel commands:

git clone https://github.com/playx18/gnome-autotheme
cd gnome-autotheme
./install.sh

Now try changing wallpaper or change GNOME appearance from Dark style to Default.

How

We use Wallust to extract color theme from wallpaper and generate adw-colors compatible gtk.css. Regular wal cache is also generated which allows using pywal for VSCode/Vim/Firefox/whatever as well.

We get notified of wallpaper change or style change using dbus, you can check Rust source code for the simple program. This program is then served as a user service in systemd.

Adding templates

Simply add your template to templates/ directory, update wallust.toml, wallust-light.toml and execute ./install.sh again.

TODOs

• KDE support: figure out kreadconfig/kwriteconfig and all the available options, dbus on kde?
• Cinnamon/XFCE support: the same, figure out how dbus works there and also add DE detection.
