Vim and Ruby script : object callback possible ?

Hi all,

From Vim ruby help, there is this example :

Example Vim script: >

function! RedGem()
ruby << EOF
class Garnet
def initialize(s)
@buffer = Vim::Buffer.current
vimputs(s)
end
def vimputs(s)
@buffer.append(@buffer.count,s)
end
end
gem = Garnet.new("pretty")
EOF
endfunction


Calling by this commannd
command! -nargs=0 FOO call RedGem()


From first call by FOO cmd that make instance from new ruby Object Garnet,the instance is it still alive in order to call another gem.barmethod?

How to keep ruby objects alive in Vim buffer memory in order to reuse them ?

Thank you
Ni Va
