guard-rails/README.md

Want to restart your Rails development server whilst you work? Now you can!

guard 'rails', :port => 5000 do
  watch('Gemfile.lock')
  watch(%r{^(config|lib)/.*})
end

Lots of fun options!

• :port is the port number to run on (default 3000)
• :environment is the environment to use (default development)
• :start_on_start will start the server when starting Guard (default true)
• :force_run kills any process that's holding open the listen port before attempting to (re)start Rails (default false).
• :deamon runs the server as a daemon, without any output to the terminal that ran guard (default false).
• :timeout waits this number of seconds when restarting the Rails server before reporting there's a problem (default 20).

This is super-alpha, but it works for me! Only really hand-tested in Mac OS X. Feel free to fork'n'fix for other OSes, and to add some more real tests.
