Method FinchRootDir

pkg/path/finch_windows.go:18–30

FinchRootDir returns the path to the Finch root directory, which is %LOCALAPPDATA% on Windows. It also canonicalizes any environment variables that may be unexpanded in the path so that all paths based on it can be passed safely to other programs which may execute outside of the user's context.

// paths based on it can be passed safely to other programs which may execute outside of the user's context.

	if err != nil {
		return "", err

	if strings.Contains(expandedPath, "&") || strings.Contains(expandedPath, `"`) {
		return "", fmt.Errorf("unexpected LOCALAPPDATA path %q", expandedPath)
