This overlay is registered in the Gentoo database as spring (see https://repos.gentoo.org).
How to use that overlay:
eselect-repository is not installed: emerge eselect-repositoryspring repository: eselect repository enable spring/etc/portage/repos.conf/eselect-repo.confemerge --sync spring/var/db/repos/springspring and springlobby packages:echo "games-strategy/spring ~amd64" >> /etc/portage/package.accept_keywords
echo "games-util/springlobby ~amd64" >> /etc/portage/package.accept_keywordsNote: package.accept_keywords can be either a file or a directory (see man portage for details).
Note: installing the engine through emerge is optional, most lobbies can automatically (and insecurely) download it on demand. To disable the later for SpringLobby, do mkdir ~/.spring && touch ~/.spring/engine (SpringLobby will still offer and try to download, but it will actually fail).
Version 105.0 is the current stable, and 9999 is the latest from the master (= maintenance) branch.
Update on 2022-01-02: spring-105.0 is currently broken because of an incomplete source tarball (tracked by https://springrts.com/mantis/view.php?id=6446). Use spring-9999 that is also pointing today to the 105.0 version.
emerge -a '=games-strategy/spring-105.0' # For stable
emerge -a '=games-strategy/spring-9999' # For latestVersion 0.273 is the current stable, and 9999 is the latest from the master branch.
emerge -a '=games-util/springlobby-0.273' # For stable
emerge -a '=games-util/springlobby-9999' # For latest
If you installed the engine via the above procedure, then:
