A Gentoo ebuild repository (overlay) for the Flatpak application distribution format.
Note that this only installs the Flatpak application, for usage see the main Flatpak website.
The Flatpak ebuild does not track actual applications installed by Flatpak like Gentoo would. Flatpak uses OSTree to install and track applications and runtimes in /var, so the base Gentoo installation will not be touched. It is also possible to install applications and runtimes on a per user basis only.
There are two main methods for making use of this repository, discussed in the sections below.
For the local repository method, create a /etc/portage/repos.conf/flatpak-overlay.conf file containing the following bit of text.
[flatpak-overlay]
priority = 50
location = <repo-location>/flatpak-overlay
sync-type = git
sync-uri = https://github.com/fosero/flatpak-overlay.git
auto-sync = Yes
Change repo-location to a path of your choosing and then run emaint -r flatpak-overlay sync, Portage should now find and update the repository.
You can also use the Layman tool to add and sync the repository, read the instructions on the Gentoo Wiki.
