Vegas aims to solve the simple problem of creating executable versions of Sinatra/Rack apps.


Currently, Vegas just includes a single class Vegas::Runner which wraps your Sinatra app to give it command line options, daemon-ization, PID/URL tracking, and browser launching.

Lets say you have a gem with a sinatra application. With Vegas you can create a bin that looks like

#!/usr/bin/env ruby
# ./bin/myapp

require File.expand_path(File.dirname(__FILE__) + "/../lib/myapp")
require 'vegas', 'myapp')

See the website: for full usage/options.


Using vegas (and gems that depend on it) on Windows works but isn't 100% the same. Daemon-ization and browser launching work, but you will see duplicate messages. Some options might also be lost in the process. I suggest running Vegas apps in windows with the -F (foreground) flag.

If you see a warning like:

`expand_path': couldn't find HOME environment -- expanding `~/.vegas' (ArgumentError)

You have to set your HOME path:

c:\> set HOME=%HOMEPATH%


sudo gem install vegas
