I'm not sure what you mean, but every Object has a class method which gives you it's class.

irb(main):008:0> 1.class
=> Fixnum
irb(main):009:0> 'foo'.class
=> String

What do you exactly have in mind ? Ruby classes are already Ruby
objects ... so if you need to manipulate classes as objects you already
can

obj = Class.new

<manipulate obj>

instance = obj.new

source code here
---------------------
class Name
  def initialize
  end
   .....
end
-----------------------

obj=Name.new

now my question is ,how to create above source code ?.

Maybe he means something like extracting Ruby code for the class out of the object... That would be very interesting, because you could really delve in and affect all sorts of bug fixes for compiled extensions.

AFAIK, this is not possible. Take a look at ruby2ruby

I'm guessing something like

a = YourClass.new
a.to_ruby

class Object - RDoc Documentation

source code here

---------------------
class Name
  def initialize

obj=Name.new

now my question is ,how to create above source code from obj?.

actually jruby will create java object to ruby object
but that ruby object(from java object) is not in source code format

so i am asking this question ......

If you want to create the class definition source code when having an
instance only there is no way - at least no standard way. You would
have to dig into the Ruby interpreter to do that.

arggh, i'm feeling dumb, i've just downloaded the gem, but i do not know how to require it. The rdoc does not give an example.

kind regards -botp

pls ignore. dumb indeed. forgot the 'rubygems' require. gotta change my irb ini.

my next question is, will this run on windows?
if yes, examples pls.

thanks and kind regards -botp

Well, it could be sort of possible, but partly pointless:
You could start a ruby process that then loads a file, but before loading, read the file. You could then create objects that contain the code (as a string, probably) for classes in the original file.
Then when you ask an object, "what class are you?", you will have a little clipboard (or PDA) to lookup his/her class name and fetch your class_code string.

From there it would be possible to alter the class_code string, then re"load" that class into the interpreter...
circular? could be
pointless? maybe
fun? probably
