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

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 ?.

source code here

class Name
def initialize
end

end

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.

class Object - RDoc Documentation

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

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.

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
