Method AddError

shell/shell.go:344–352

AddError adds the given error to the error stack if it is non-nil, and calls the Cancel function if set, to stop execution. This is the main way that shell errors are handled. It also prints the error.

(err error)

// This is the main way that shell errors are handled.
// It also prints the error.
func (sh *Shell) AddError(err error) error {
	if err == nil {
		return nil
	}
	sh.Errors = append(sh.Errors, err)
	logx.PrintlnError(err)
	sh.CancelExecution()
	return err
}
