cd Gradience
meson builddir --prefix=/usr/local
sudo ninja -C builddir install

Local build (for testing and development purposes):

git clone https://github.com/GradienceTeam/Gradience.git
cd Gradience
meson builddir
meson configure builddir -Dprefix="$(pwd)/builddir/testdir"
ninja -C builddir install
ninja -C builddir run

[NOTE] During testing and developement, as a convenience, you can use the local.sh script to quickly rebuild local builds.

Building using flatpak-builder:

1. Open Terminal
2. Run git clone https://github.com/GradienceTeam/Gradience.git && cd Gradience
3. Add the gnome-nightly Flatpak repository flatpak remote-add --if-not-exists gnome-nightly https://nightly.gnome.org/gnome-nightly.flatpakrepo
4. Install the master version of GNOME SDK: flatpak install org.gnome.Sdk/x86_64/master org.gnome.Platform/x86_64/master
5. Run flatpak-builder --install --user --force-clean repo/ com.github.GradienceTeam.Gradience.json

Alternatively, open the project with GNOME Builder, then build and run it.

Setup Tutorial

Libadwaita applications

No additional setup is required for native Libadwaita applications.

For Flatpak Libadwaita applications, you need to override their permissions:

• Run sudo flatpak override --filesystem=xdg-config/gtk-4.0 or
• Use Flatseal and adding xdg-config/gtk-4.0 to Other files in the Filesystem section of All Applications

Vanilla GTK 4 applications

Use this guide to theme vanilla GTK 4 applications.

GTK 3 applications

• Install and apply the adw-gtk3 theme (don't forget to install the Flatpak package!)
• For Flatpak applications, you need to override their permissions:
  • Run sudo flatpak override --filesystem=xdg-config/gtk-3.0 or
  • Use Flatseal and adding xdg-config/gtk-3.0 to Other files in the Filesystem section of All Applications
