def_notifier(prefix = "", output_method = click to toggle source

Define a new Notifier output source, returning a new CompositeNotifier with the given prefix and output_method.

The optional prefix will be appended to all objects being inspected during output, using the given output_method as the output source. If no output_method is given, StdioOuputMethod will be used, and all expressions will be sent directly to STDOUT without any additional formatting.
