Class Method Details

.action_hook(name, hook_name = nil, &block) ⇒ Array

Registers a callback to be called when a specific action sequence is run. This allows plugin authors to hook into things like VM bootup, VM provisioning, etc.

Parameters:

  • name (String) —

    Name of the action.

  • hook_name (Symbol) (defaults to: nil) —

    The location to hook. If this isn't set, every middleware action is hooked.

Returns:

  • (Array) —

    List of the hooks for the given action.

def self.action_hook(name, hook_name=nil, &block)
  # The name is currently not used but we want it for the future.
  hook_name = hook_name.to_s if hook_name

  hook_name ||= ALL_ACTIONS
  components.action_hooks[hook_name.to_sym] << block
end

.command(name, **opts, &block) ⇒ Object

Defines additional command line commands available by key. The key becomes the subcommand, so if you register a command "foo" then "vagrant foo" becomes available.

Parameters:

  • name (String) —

    Subcommand key.

  if name.to_s !~ /^[-a-z0-9]+$/i
    raise InvalidCommandName, "Commands can only contain letters, numbers, and hyphens"
  end

  # By default, the command is primary
  opts[:primary] = true if !opts.key?(:primary)

  # Register the command
  components.commands.register(name.to_sym) do
    [block, opts]
  end

  nil
end

.communicator(name = UNSET_VALUE, &block) ⇒ Object

Defines additional communicators to be available. Communicators should be returned by a block passed to this method. This is done to ensure that the class is lazy loaded, so if your class inherits from or uses any Vagrant internals specific to Vagrant 1.0, then the plugin can still be defined without breaking anything in future versions of Vagrant.

Parameters:

  • name (String) (defaults to: UNSET_VALUE) —

    Communicator name.

.config(name, scope = nil, &block) ⇒ Object

Defines additional configuration keys to be available in the Vagrantfile. The configuration class should be returned by a block passed to this method. This is done to ensure that the class is lazy loaded, so if your class inherits from any classes that are specific to Vagrant 1.0, then the plugin can still be defined without breaking anything in future versions of Vagrant.

Parameters:

  • name (String) —

    Configuration key.
