GOG-SYNC

Please note that this is alpha software, you should not trust it.

A small tool to synchronize the stuff in a GOG library with a local folder.

It builds on the work of the unofficial GOG API Documentation.

This is the first time I am building something with rust, so beware :)

Installation

Install from crates.io.

cargo install gog-sync

Configuration

The configuration file is in the config folder as described by the xdg specification with a prefix of gog-sync.

For example on macOS or Linux

~/.config/gog-sync/config.json

A bare configuration with default values before first use:

{
  "gameStorage": ".",
  "movieStorage": ".",
  "content": {},
  "data": {},
  "extras": {},
  "osFilters": [],
  "languageFilters": [],
  "skipMovies": false,
  "skipGames": false
}

• gameStorage: Where to save games
• movieStorage: Where to save movies
• content: A map, content id => hash
• data: A map, data url => hash
• extras: A map, extra url => hash
• osFilters: An array of operating systems. If it is not empty, game data is limited to the ones in the list.
• languageFilters: An array of languages. If it is not empty, game data is limited to the ones in the list.
• resolutionFilters: An array of resolutions. If it is not empty, movie data is limited to the ones in the list.
• skipMovies: Whether to skip movie content
• skipGames: Whether to skip game content

Valid values for osFilter:

• linux
• mac
• windows

Check on gog.com which languages are available.

An incomplete list of resolutions on gog:

• DVD
• 576p
• 720p
• 1080p
• 4k

You should have no need of changing content, data or extras, as these are used to determine whether specific content is up to date.
