- When the user does not specify the PROTONPATH, attempt to download the latest Proton if Proton cannot be found in either the Steam compat tools or local cache. Otherwise, prioritize referring to existing ones -- $HOME/.local/share/Steam/compatibilitytools.d and $HOME/.cache/ULWGL.
- Effectively, new installations will always download the latest Proton, while existing ones will simply be warned of a later version. Downloading is avoided if the latest version already exists in the cache, and the cache will be used as a last resort to set the variable. When we're unable to find an existing Proton or download one, we raise an error.
- Setup can fail when creating the symlink if the pfx somehow exists already. One case this can probably happen is if the user references a Steam created prefix as the WINEPREFIX since pfx directory would exist.
- Also, update the test to check for expected environment variables in the dictionary. Notably, when a valid ULWGL_ID is set, the STEAM_COMPAT_ID and related env var should be the stripped ULWGL_ID.
- Before, the executable and its options were joined as a single string to be executed. Instead, prefer separating them as distinct arguments. As a result, the command as an Array becomes something like:
['/home/foo/.local/share/ULWGL/ULWGL', '--verb', 'waitforexitandrun', '--', '/home/foo/GE-Proton8-30/proton', 'waitforexitandrun', '/home/foo/foo.exe', '-foo', '-bar', '-baz']
- After specifying the executable, all arguments following the first were ignored unless they were escaped to be interpreted as part of the first argument.
- Reimplement parse_args to simply return a single positional argument string or a Namespace object. As a result the new usage will be:
$ gamelauncher.py /home/foo/foo.exe
$ gamelauncher.py /home/foo/foo.exe -opengl ...
$ gamelauncher.py --config example.toml
- Everything following the program will be interpreted as a single positional argument and this removes the need for quotes for the envvar usage. The optional arguments: --exe, --options, --store and --verb will no longer be supported.
- Enable users to optionally specify the game's distribution platform (store). This allows them to properly apply a fix from a specific store rather than Steam's to their game's WINE prefix. As a side effect, this allows users to apply a protonfix from other stores (e.g. gog).
- In its current form, executing the gamelauncher script can be tedious especially when not using a modern shell that supports auto completions. For instance:
$ WINEPREFIX=$HOME/Games/epic-games-store GAMEID=egs PROTONPATH=$HOME/.steam/steam/compatibilitytools.d/GE-Proton8-28 ./gamelauncher.sh $HOME/Games/epic-games-store/drive_c/Program Files (x86)/Epic Games/Launcher/Portal/Binaries/Win32/EpicGamesLauncher.exe -opengl -SkipBuildPatchPrereq
- By rewriting the gamelauncher script in Python, we can support reading from a configuration file(s) instead which increases ease of use and provides better organization. This effectively results in this:
$ gamelauncher.py --config example.toml
- Additionally, due to the rich Python ecosystem, the rewrite leaves room for future features and formal testing if needed.
