Wyvern is a command-line tool written in rust that is meant to make downloading GOG games and associated activities easier and faster on linux. It features:

• Downloading games

• Installing games without need for the graphical installers

• One-command updating of games to their latest versions, while only updating files that have changed between versions.

• GOG Connect functionality so you can scan for and claim games without leaving the terminal

• Syncing save files to a filesystem backup(with integration with cloud services being worked on).

• Optional(compile with the 'eidolonint' feature) integration with eidolon, so that it automatically registers installed games to eidolon.

The GitHub repo is a mirror of the main sr.ht repository.

Wyvern is available on crates.io, installable via cargo:

cargo install wyvern
