Add new configuration directory

[ihaveamac]

Maybe I should add a specific one? Some config files could go here. Don't know exactly what though.

• Windows: %APPDATA%\fuse3ds
• macOS: ~/Library/Application Support/fuse3ds (or maybe use the one below too)
• Linux: ~/.config/fuse3ds

For Linux, does this application support the XDG Base Directory Standard? That would be nice to have.

Also for MacOS, you should support both, have it look at the Application Support first if the files are there, then check in the .config folder.

It doesn't use a standard like that right now, since it has no configuration directory specific to this application. The only paths it checks right now for boot9/seeddb are current dir, ~/.3ds, and ~/3ds. The first one is taken from some of yellows8's projects and shared with another one of mine, the second is easier for Windows users to create, because Windows/File Explorer doesn't easily allow creating directories starting with a period.

This new one would be specific to fuse-3ds and would store more than just boot9/seeddb (if the user wants to put them here). I would need to read more about the standard but it seems XDG_CONFIG_HOME generally points to $HOME/.config.

URL is now https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html (first one did not load for me anymore)

For fuse-3ds specific configuration (e.g. update check/notify settings), I'm thinking of going with only one fixed path per OS: %APPDATA%\fuse-3ds, ~/Library/Application Support/fuse-3ds, and $XDG_CONFIG_HOME/fuse-3ds. Unlike the one that store boot9/seeddb/etc, which can be different paths, since some other programs may now support them (e.g. ctrcdnfetch uses these paths to read certificates).

03d1931 new config_dir variable that contains these paths, but is currently unused.

For Linux, it uses $XDG_CONFIG_HOME/fuse-3ds if it's set, checks paths of $XDG_CONFIG_DIRS (defaults to /etc/xdg if not set) to see if fuse-3ds already exists in one of them, then falls back to ~/.config/fuse-3ds. I think this is how the standard works.

[CuriousTommy]

The only concern I have with using XDG_CONFIG_DIRS is that the user may be required to use root to store files in there (especially if the default location is fuse-3ds), otherwise everything is fine (if you intend to keep it in a config directory).

Thanks again for using the XDG standard!

According to https://wiki.archlinux.org/index.php/XDG_Base_Directory XDG_CONFIG_DIRS is for system directories, and defaults to /etc/xdg. Though the standard also says that XDG_CONFIG_DIRS has a list of extra directories to search in addition to XDG_CONFIG_HOME (if it's not set), so I decided to check it just in case. fuse-3ds would never automatically create a config in any XDG_CONFIG_DIRS directories, only used if the user explicitly sets it up, knowing that it may require elevated privileges.

Commits 3dfc024 8c82ce6 aa75770 58b4529 add support for using update.cfg in this new configuration directory. Only tested on Mac so far.

Tested on Windows & Linux now (including XDG_CONFIG_HOME).

Makes sense. I was thinking why you need to use XDG_CONFIG_DIRS, but I can see why you want to have support for it.
