Automatically install your host GTK+ theme as a Flatpak.
Requirements
In addition to bash and coreutils (which should be available out of the box on most distros),
the following binaries are needed:
ostree
appstream-util
The packages that provide these vary by distro:
Fedora Silverblue: These packages should be available out of the box.
Fedora: dnf install ostree libappstream-glib
Debian/Ubuntu and variants: apt install ostree appstream-util
Arch/Manjaro: pacman -S ostree appstream-glib
OpenSUSE: zypper install libostree appstream-glib
Usage
Run ./stylepak install-system and ./stylepak install-user to grab your current GTK+ theme and
install it as a Flatpak into either the system or user installation, respectively. You can also
pass a theme name, e.g. ./stylepak install-user Adapta, and stylepak will install that theme
instead of your current one.
Use ./stylepak clear-cache to clear the theme storage cache.
