Go, XDG, go!

This is go-xdg, a little library to help you use the XDG base directory spec.

(There are other XDG specs, that might get included in time. Patches welcome.)

Sample usage

Let's say you are writing an app called “frobz”. It has a config file and a sqlite database. You'd do something like this:

configFileName, err := xdg.Config.Find("frobz/config.txt")
if err == nil {
    // a config file exists! load it...
}
dbFileName, err := xdg.Data.Ensure("frobz/frobz.db")
// now the file and all its directories exist; it's up to you to
// determine if it's empty, etc.

Resources

Both Find and Ensure take a resource to construct the path they return.

A resource is usually an application name (or a well-known shared resource pool name, such as icons), followed by a filename. However nothing in the standard nor in this library limits you to that; you may store e.g. your application's configuration in just $XDG_CONFIG_HOME/application.conf (in which case the "resource" here would be just application.conf), or in a sub-directory of an application-specific directory.
