That is nothing to do with RoR of course, but just write a file.rb run
it by
ruby file.rb
You can use puts etc to access the console.

I want to create a new console using ruby code. From the new console,
i’ll execute my commands.

What do you mean by create a new console? Please describe in more
detail what you are trying to do.
Colin
I’m creating a new object for a class using irb. At that time, if the
object is created successfully, a new console should be open. The newly
opened console should act as the created object.
so that i can execute all the instance methods through the newly opened
console, without prefixing object to the methods.
am i clear?

You can use the ruby method ‘system’ to run system commands to open a
command shell if that is what you mean.
Colin
No Colin, i don’t want to execute system commands.
For eg,
In the above mentioned steps, while i’m creating a object, a new console
should open, which represents the object.
I just give the instance method names in the opened console.i.e,
get_details() instead of @obj.get_details().
Is this making sense?

Which OS are you running (Ubuntu, XP etc)? How do you open the first
console?

Please don’t top post, it makes it difficult to follow the thread,
insert your reply into the previous post, thanks.
So to open a console you open a terminal window and then run irb. If
you want to open another console then AFAIK you will need to run a
system command to open another terminal and run irb. Something like
system( ‘gnome-terminal -e irb’)
Unless someone knows another way.

Sorry Colin, i think you didn’t get my requirement. Thank you very much
for your valuable effort.
Anyway, i’m working on this. If i get the solution, i’ll reply. Thanks.
I think you can use Irb to jump into another object :
http://www.ruby-forum.com/topic/182335
irb Mix Tape — err.the_blog (3rd paragraph)
Here is something that I created for myself to have capybara console:
It creates and object, extends it with the capybara api and jumps into
it.
I couldn’t find an easier way to jump into an object with irb at the
beginning of the session.
I hope this will help.

The concept of nested irb shells is already supported by irb. You
merely
have to use the method “irb ” while in irb to insert yourself
into
the instance’s namespace.
irb(main):001:0> class Test
irb(main):002:1> def test_method
irb(main):003:2> “test method called correctly”
irb(main):004:2> end
irb(main):005:1> end
=> nil
irb(main):006:0> irb Test.new
irb#1(#Test:0x1c67478):001:0> test_method
=> “test method called correctly”
irb#1(#Test:0x1c67478):002:0> quit
=> #<IRB::Irb: @scanner=#RubyLex:0x1bac510,
@context=#IRB::Context:0x1bacbc8, @signal_status=:IN_EVAL>
irb(main):007:0> quit
bash%
