Subject: [ruby-talk:23619] sleeping, calling methods inside class defs

ruby 1.6.3 (2001-03-19) [i386-cygwin]

Hi,

1. Why is the following sleeping?

It just sleeps forever; how can I achieve it that it uses the method 
above, not the sleep method?.

-----
class Tobi

   def sleep
     print "rzzzzz..\n"
   end

   sleep

end
-----

2. I know this is basic, but I don't get it:
-----
class Tobi

   def hi
     print "hi!\n"
   end

   hi

end
-----
gives NameError: :7: undefined local variable or method `hi' for Tobi:Class

-----
class Tobi

   def hi
     print "hi!\n"
   end

   self.hi

end
-----
gives 7: undefined method `hi' for Tobi:Class (NameError)

-----
class Tobi

   def hi
     print "hi!\n"
   end

end

Tobi.new.hi
-----
works; but how can I use the method inside the class?


-----
class Tobi

   def hey
     print "hey!\n"
   end

   def hey_ho
     hey
     print "ho!\n"
   end

end

Tobi.new.hey_ho
-----
here I can call the first method inside the second, when calling the 
second method from outside the class def.

How to call a method inside the class def?

-----
class Tobi

   def hey
     print "hey!\n"
   end

   def hey_ho
     hey
     print "ho!\n"
   end

   @hey_ho = self.hey_ho

end
-----
doesn't work.

TIA,

Tobi
