It's probably possible but may be more trouble then it's worth. What
about something like this instead?
module Ruby
def ruby(cmd, options={}, &block)
temp_name = "/tmp/#{Time.now.strftime("%m%d%H%M%S")}" + ".rb"
begin
put(cmd, temp_name, :mode => 0700)
send(run_method, "ruby #{temp_name}", options, &block)
ensure
delete temp_name
end
end
end
Capistrano.plugin :script, Ruby
task :foo do
script.ruby "10.times { puts `uname -a` }"
end
