Something like PPerl for Ruby?

Question

I've used PPerl for deamon like processes.

This program turns ordinary perl scripts into long running daemons, making subsequent executions extremely fast. It forks several processes for each script, allowing many proceses to call the script at once.

Does anyone know of something like this for ruby? Right now I am planing on using a wrapper around curl to call a REST WebService written in Sinatra running on JRuby. I'm hoping there is a simpler option.

Answer 1

You mean like daemons?

Simple example of in-process daemonization

  require 'rubygems'
  require 'daemons'

  Daemons.daemonize


  loop do
    `touch /tmp/me`
    sleep 1
  end

Also, instead of using curl, have you looked at rest-client?

Answer 2

Have you looked at using nailgun? It sets up a background JVM process that your scripts execute in. That way you can use jruby w/o incurring the JVM startup time you would normally get with each script run.
