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.
