Hmm, mine also resolves a leading tilde in these variables. And if $HOME is not specified it tries to resolve the user’s home directory by user.Current().HomeDir. Maybe that’s overkill, I have to check the XDG spec.

But I’m definitely missing os.UserDataDir(). That’s a bummer.

Ok, the standard library implementation is wonky at best, at least in regards to XDG, because it really doesn’t implement it properly. https://github.com/golang/go/issues/62382 I stick to my own code then. It doesn’t properly support anything else than Linux or Unixes that use XDG, but personally, I don’t care about them anyway. And the cross-platform situation is a giant mess. Unsurprisingly.
