func Expand ¶

func Expand(path string) (string, error)

Expand resolves shell-style tilde expansions in a path:

• "~" → current user's home directory
• "~/subpath" → current user's home directory + subpath
• "~username" → named user's home directory
• "~username/subpath" → named user's home directory + subpath

All other paths are returned unchanged. "." and ".." components are not resolved here; callers should pass the result through filepath.Abs or filepath.Clean as needed.

Note: "~username" lookup uses the OS user database. An error is returned if the named user does not exist.

func MustExpand ¶

func MustExpand(path string) string

MustExpand is like Expand but returns the original path unchanged on error instead of surfacing the error. Useful in contexts where errors are non-fatal (e.g. serving default directories).
