pretty_print(q) public

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.
