Ruby's to_s method question (from Axe book 2nd edition)
- by prosseek
According to the axe book (2nd edition), we can use to_s as follows.
class Song
def to_s
"Song"
end
end
song = Song.new()
song.to_s
But, it doesn't give me anything, in order to print something to the stdout, I should run
def to_s
p "Song"
end
Is there any change since the ruby 1.8.2 when the book was written for?
My ruby version info is 1.8.7 for Mac.
ruby 1.8.7 (2009-06-08 patchlevel 173) [universal-darwin10.0]
