Just make len 0 a special case
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.
