A default pretty printing method for general objects. It calls pretty_print_instance_variables to list instance variables.

If self has a customized (redefined) inspect method, the result of self.inspect is used but it obviously has no line break hints.

This module provides predefined pretty_print methods for some of the most commonly used built-in classes for convenience.

A default pretty printing method for general objects that are detected as part of a cycle.

Is inspect implementation using pretty_print. If you implement pretty_print, it can be used as follows.

  alias inspect pretty_print_inspect

However, doing this requires that every class that inspect is called on implement pretty_print, or a RuntimeError will be raised.

Returns a sorted array of instance variable names.

This method should return an array of names of instance variables as symbols or strings as: +[:@a, :@b]+.
