go-homedir
This is a Go library for detecting the user's home directory without the use of cgo, so the library can be used in cross-compilation environments.
Usage is incredibly simple, just call homedir.Dir() to get the home directory
for a user, and homedir.Expand() to expand the ~ in a path to the home
directory.
Why not just use os/user? The built-in os/user package requires
cgo on Darwin systems. This means that any Go code that uses that package
cannot cross compile. But 99% of the time the use for os/user is just to
retrieve the home directory, which we can do for the current user without
cgo. This library does that, enabling cross-compilation.
