Overview

A DSL to be included into Ridley::Connection. Instance functions of the same name as Chef a resource are coerced into class functions of a class of the same name.

This is accomplished by returning a Ridley::Context object and coercing any messages sent to it into a message to the Chef resource’s class in Ridley.

Examples:

class Connection
  include Ridley::DSL
end

connection = Ridley::Connection.new
connection.role.all

The 'role' function is made available to the instance of Ridley::Connection by including
Ridley::DSL. This function returns a Ridley::Context object which receives the 'all' message.
The Ridley::Context coerces the 'all' message into a message to the Ridley::Role class and
sends along the instance of Ridley::Connection that is chaining 'role.all'

connection.role.all => Ridley::Role.all(connection)

Any additional arguments will also be passed to the class function of the Chef resource's class

connection.role.find("reset") => Ridley::Role.find(connection, "reset")

instantiating new resources

class connection
  include Ridley::DSL
end

connection = Ridley::Connection.new
connection.role.new(name: "hello") => <#Ridley::Role: @name="hello">

New instances of resources can be instantiated by calling new on the Ridley::Context. These messages
will be send to the Chef resource's class in Ridley and can be treated as a normal Ruby object. Each
instantiated object will have the connection information contained within so you can do things like
save a role after changing it's attributes.

r = connection.role.new(name: "new-role")
r.name => "new-role"
r.name = "other-name"
r.save

connection.role.find("new-role") => <#Ridley::Role: @name="new-role">
