method
Os.save_dir
Os.save_dir(app) -> string
The per-user directory where an application should store save files, named for the app. Which directory that is, is the platform's decision, not the program's:
| | |
| --- | --- |
| macOS | ~/Library/Application Support/<app> |
| Linux | $XDG_DATA_HOME/<app>, or ~/.local/share/<app> |
An XDG variable that is set but empty falls back to the default, as the spec requires. The path is returned as a string; creating the directory and reading/writing files is the filesystem library's job (see the config_dir/cache_dir companions).
On macOS save_dir and config_dir are the same directory — Apple's home for a config file that is not an NSUserDefaults plist is Application Support too. On Linux XDG separates them, and so does this.
