Question

The __repr__ function of python is fancy as it is called when print OBJECT is used automatically.

Is there a ruby equivalence for it? I thought it was to_s, but, I had p OBJECT doesn’t seem to call the to_s method.

Added

I got something wrong, p OBJECT seems to call to_s method as follows.
I got some hints from my the answers to my other question. – Ruby's to_s method question (from Axe book 2nd edition)

# Sample code from Programing Ruby, page 24
class Song
  def to_s
    "Song"
  end
end

class Songson < Song
  def to_s
    super + "<Songson>"
  end
end

song = Songson.new()
p song

Answer 1

  obj.inspect => string

Returns a string containing a human-readable representation of obj. If not overridden, uses the to_s method to generate the string.

   [ 1, 2, 3..4, 'five' ].inspect   #=> "[1, 2, 3..4, \"five\"]"
   Time.new.inspect                 #=> "Wed Apr 09 08:54:39 CDT 2003"

 obj.to_s => string

Returns a string representing obj. The default to_s prints the object‘s class and an encoding of the object id. As a special case, the top-level object that is the initial execution context of Ruby programs returns “main.’‘
