Exiting a Sinatra App from Within the App

[Keith Bennett]

I'd like to know how to programmatically exit a Sinatra app *from within the app itself*.

I want to use Sinatra as a means of receiving control and configuration commands while my app does something unrelated to the Sinatra stuff.  I'd like one of the control commands to be 'exit'.  Ruby's 'exit' method just seems to result in Sinatra recovering and resuming.  I found this in base.rb that I think confirms this:

  at_exit { Application.run! if $!.nil? && Application.run? }

So far the only way I've found is to call Ruby's exit! method, but that bypasses exit hooks and is not a very clean solution.

Is there no way to programmatically tell Sinatra to stop?

I think this is not possible, and using exit will not work because it raises a SystemExit exception and the exceptions raised inside routes are handled by sinatra.

Maybe you can kill the process, but this will be really ugly.

Not a problem!

In the newest Sinatra from the master branch you do it like that:

require 'sinatra'

get '/' do
  Sinatra::Application.quit!
end

Please note that it is not released yet. This feature will be avaliable in Sinatra 1.5.0.
So if you want to use most recent Sinatra version with this feature right now, use this declaration in your Gemfile:

gem 'sinatra', :github => 'sinatra/sinatra'

Build great apps!

Maybe this will help you.
