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.
# File pp.rb, line 257 def pretty_print(q) if /\(Kernel\)#/ !~ method(:inspect).inspect q.text self.inspect elsif /\(Kernel\)#/ !~ method(:to_s).inspect && instance_variables.empty? q.text self.to_s else q.pp_object(self) end end
A default pretty printing method for general objects that are detected as part of a cycle.
# File pp.rb, line 269 def pretty_print_cycle(q) q.object_address_group(self) { q.breakable q.text '...' } end
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.
# File pp.rb, line 291 def pretty_print_inspect if /\(PP::ObjectMixin\)#/ =~ method(:pretty_print).inspect raise "pretty_print is not overridden for #{self.class}" end PP.singleline_pp(self, '') end
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]+.
# File pp.rb, line 280 def pretty_print_instance_variables instance_variables.sort end
