Function IsLexicallyInRoot

internal/pathrs/path.go:34–38

IsLexicallyInRoot is shorthand for strings.HasPrefix(path+"/", root+"/"), but properly handling the case where path or root have a "/" suffix. NOTE: The return value only make sense if the path is already mostly cleaned (i.e., doesn't contain "..", ".", nor unneeded "/"s).

(root, path string)

// NOTE: The return value only make sense if the path is already mostly cleaned
// (i.e., doesn't contain "..", ".", nor unneeded "/"s).
func IsLexicallyInRoot(root, path string) bool {
	root = strings.TrimRight(root, "/")
	path = strings.TrimRight(path, "/")
	return strings.HasPrefix(path+"/", root+"/")
}

// LexicallyCleanPath makes a path safe for use with filepath.Join. This is
// done by not only cleaning the path, but also (if the path is relative)
