Public Instance methods
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 243
243: def pretty_print(q)
244: if /\(Kernel\)#/ !~ method(:inspect).inspect
245: q.text self.inspect
246: elsif /\(Kernel\)#/ !~ method(:to_s).inspect && instance_variables.empty?
247: q.text self.to_s
248: else
249: q.pp_object(self)
250: end
251: end
A default pretty printing method for general objects that are detected as part of a cycle.
# File pp.rb, line 255
255: def pretty_print_cycle(q)
256: q.object_address_group(self) {
257: q.breakable
258: q.text '...'
259: }
260: 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 277
277: def pretty_print_inspect
278: if /\(PP::ObjectMixin\)#/ =~ method(:pretty_print).inspect
279: raise "pretty_print is not overridden."
280: end
281: PP.singleline_pp(self, '')
282: end
