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.

Variables

var DisableCache bool

DisableCache will disable caching of the home directory. Caching is enabled by default.

Functions

func Dir

func Dir() (string, error)

Dir returns the home directory for the executing user.

This uses an OS-specific method for discovering the home directory. An error is returned if a home directory cannot be detected.

func Expand

func Expand(path string) (string, error)

Expand expands the path to include the home directory if the path is prefixed with `~`. If it isn't prefixed with `~`, the path is returned as-is.

func Reset

func Reset()

Reset clears the cache, forcing the next call to Dir to re-detect the home directory. This generally never has to be called, but can be useful in tests if you're modifying the home directory via the HOME env var or something.
