Shameless plug: I am the author.
Are there abstractions available around the XDG specifications to resolve the proper paths?
Use the environment variables.
I do. But you might have misunderstood my question. I was not asking for assistance. I was just curious if there are libraries available which allow easy adoption of the XDG specification. I imagine that such abstractions would be useful for multi-platform software and generally to lower the bar for adoption.
Depends on the programming language. In C# for example, there’s an API to get special folder paths that works in all supported environments (Windows, Linux, MacOS, Android, and I think iOS too). On Linux, it includes fallbacks in case the environment variables aren’t set.
What language? Python has PyXDG.
In shell it’s simply
XDG_DATA_HOME="${XDG_DATA_HOME:-"$HOME"/.local/share}" XDG_CONFIG_HOME="${XDG_CONFIG_HOME:-"$HOME"/.config}" etc.
Thanks, I did not know about PyXDG. That was the type of thing I was asking about.
