Vagrant is only guaranteeing that the plugin definition superclass (the
Vagrant.plugin("1") part) is backwards compatible. Anything else, such
as Vagrant::Command::Base and so on, will likely change in future
versions. Beacuse of this, plugins should only immediately expose their
definition.
In order to support loading the other classes, plugins should defer
loading to the "activation" phase of a plugin. This can be done using
the `activated` block:
class MyPlugin < Vagrant.plugin("1")
name "my plugin"
activated do
require "myplugin/my_command"
end
command("foo") { MyCommand }
end
Plugin activation is done at two specific times:
* Right when a Vagrant::Environment is created and the global plugins
(such as from ~.vagrantrc) are loaded.
* Right before loading configuration, but after the Vagrantfiles have
been evaluated. This allows plugins to be defined within these files
as well.
Easy commands are well... easy! They don't offer the full power of
creating a completely custom command class, but they let you do the
basics (what almost everyone needs) with minimal fuss. Example:
class MyPlugin < Vagrant.plugin("1")
name "my-plugin"
easy_command "foo" do |action|
puts "HELLO!"
end
end
NOTE: The "action" stuff isn't done yet, but will be soon!
