Should I define a main method in my ruby scripts?

I usually use

if __FILE__ == $0
  x = SweetClass.new(ARGV)
  x.run # or go, or whatever
end

So yes, you can. It just depends on what you are doing.

I've always found $PROGRAM_NAME more readable than using $0. Half the time that I see the "Perl-like" globals like that, I have to go look them up.


if __FILE__ == $PROGRAM_NAME
  # Put "main" code here
end
