- Shotgun
- This is an automatic reloading version of the rackup command that's shipped with
- Rack. It can be used as an alternative to the complex reloading logic provided
- by web frameworks or in environments that don't support application reloading.
- The shotgun command starts one of Rack's supported servers (e.g., mongrel, thin,
- webrick) and listens for requests but does not load any part of the actual
- application. Each time a request is received, it forks, loads the application in
- the child process, processes the request, and exits the child process. The
- result is clean, application-wide reloading of all source files and templates on
- each request.
- Usage
- -----
- Installation:
- gem install shotgun
- Starting a server with a rackup file:
- shotgun config.ru
- Using Thin and starting on port 6000 instead of 9393 (default):
- shotgun --server=thin --port=6000 config.ru
- Running Sinatra apps:
- shotgun hello.rb
- See 'shotgun --help' for more advanced usage.

- The reloading system in Ian Bicking's webware framework served as inspiration
- for the approach taken in Shotgun. Ian lays down the pros and cons of this
- approach in the following article:
