Overview
A minimal “shim” adapter to allow Webmachine to interface with Rack. The intention here is to allow Webmachine to run under Rack-compatible web-servers, like unicorn and pow, and is not intended to allow Webmachine to be “plugged in” to an existing Rack app as middleware.
To use this adapter, create a config.ru file and populate it like so:
require 'webmachine/adapters/rack'
# put your own Webmachine resources in another file:
require 'my/resources'
run MyApplication.adapter
Servers like pow and unicorn will read config.ru by default and it should all “just work”.
And for development or testing your application can be run with Rack’s builtin Server identically to the Mongrel and WEBrick adapters with:
MyApplication.run
