# wyvern  [](https://builds.sr.ht/~nicohman/wyvern?)
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](https://git.sr.ht/~nicohman/eidolon), so that it automatically registers installed games to eidolon.
The GitHub repo is a mirror of the main [sr.ht](https://git.sr.ht/~nicohman/wyvern) repository.

## Installation
Wyvern is available on [crates.io](https://crates.io/crates/wyvern), installable via cargo:

You can download a binary that's automatically built from the latest git commit [on my website](https://demenses.net/downloads). If you want to, you can also build it from source if you have cargo installed easily:
```
git clone https://git.sr.ht/~nicohman/wyvern && cd wyvern
cargo install --path . --force
```
Plus, it's available on the AUR as
[wyvern](https://aur.archlinux.org/packages/wyvern), helpfully maintained by

In addition, you can install it as a snap [from snapcraft.io](https://snapcraft.io/wyvern).
