Sorry, cut-and-paste error :(
Removing the
IRB.setup nil
call should help. Here's the code for .irbrc:
module IRB
def IRB.start_session(*args)
workspace = WorkSpace.new(*args)
if @CONF[:SCRIPT] ## normally, set by parse_opts
$irb = Irb.new(workspace, @CONF[:SCRIPT])
else
$irb = Irb.new(workspace)
end
@CONF[:IRB_RC].call($irb.context) if @CONF[:IRB_RC]
@CONF[:MAIN_CONTEXT] = $irb.context
trap 'INT' do
$irb.signal_handle
end
custom_configuration if defined?(IRB.custom_configuration)
catch :IRB_EXIT do
$irb.eval_input
end
end
end
x = Object.new
puts "\nStarted irb shell for x"
IRB.start_session(x)
