This package provides a basic interface for the XDG Base Directory Specification
config_home() -> (string, Error)cache_home() -> (string, Error)data_home() -> (string, Error)state_home() -> (string, Error)runtime_dir() -> (string, Error)data_dirs() -> ([]string, Error)config_dirs() -> ([]string, Error)
All procedures will return the directories as configured by their relevant environment variables, if set, or the defaults prescribed in the spec otherwise.
odin-xdg assumes Linux as the host. I may refactor this to be more portable, but Linux is the primary target.
The runtime_dir procedure requires retrieving the UID in order to calculate the return value (default: /run/user/$UID). To my knowledge (and I did hunt) there is no good documented way to do this in Odin yet. Consequently, odin-xdg relies on some of the deeper parts of core that you won't find in the package docs.
I don't know how likely those parts are to change, though I know gingerBill has some packages in there that are dummy packages for future work. As such, I cannot guarantee that a future update to the language won't unexpectedly break this package. Buyer beware.
