Compatdata Redirect

Compatdata Redirect

(wiki is WIP and simplified and feature is not yet committed)

When changing the used Proton Version for a game, files in the Compatdata are changed and renewed. This does not always work good and since recent Proton Versions it is even possible, that the Compatdata has to be removed as it got broken.

stl can circumvent this problem, by allowing to map the currently selected Proton Version to a corresponding Compatdata directory. This can be configured via two different ways, by selecting either single-proton or global-proton in the corresponding "Redirect compatdata" Game Menu option. (by default this option is "disabled" - means the regular Compatdata directory is used)

#single-proton When using this option the custom Compatdata directory is stored in the compatdata/stl subdirectory as as [SteamAppID](https://github.com/frostworx/steamtinkerlaunch/wiki/SteamAppID)-[Proton Version](https://github.com/frostworx/steamtinkerlaunch/wiki/Proton-Versions) (f.e. 31337-proton-6.3-4) besides the regular Compatdata of the game.

The regular Compatdata will be replaced with a symlink pointing to the custom Compatdata If the regular Compatdata already exists, it will be

• reused, if its Proton Version matches
• renamed (with random backup suffix) if it is a real directory and the Proton Version does not match
• re-created if it is already a symlink, but points to a Compatdata using a different Proton Version

The single-proton mode also works perfectly fine in combination with the mighty One Time Proton. When using this option switching between different proton versions can no longer harm a Compatdata

#global-proton

This option works basically almost identical to the single-proton, but the custom Compatdata is stored in $STLPROTCOMPDATDIR/compatdata-[Proton Version](https://github.com/frostworx/steamtinkerlaunch/wiki/Proton-Versions) (f.e. ~/.config/stl/proton/compatdata/compatdata-proton-6.3-4) The Compatdata symlink for the game is created accordingly. Using this option it is possible to share one single Compatdata between all games using this option and the same Proton Version

(maybe adding an option in this combination which restores/migrates configuration files - f.e. files from the steamuser directory from previous Compatdata or from Backup later)
