Overview

A DDL file for the data query plugins.

Query plugins can today take only one input by convention in the DDL that is called :query, otherwise the input is identical to the standard input.

metadata :name => “Agent”,

:description => "Meta data about installed MColletive Agents",
:author      => "R.I.Pienaar <[email protected]>",
:license     => "ASL 2.0",
:version     => "1.0",
:url         => "http://marionette-collective.org/",
:timeout     => 1

dataquery :description => “Agent Meta Data” do

input :query,
      :prompt => "Agent Name",
      :description => "Valid agent name",
      :type => :string,
      :validation => /^[\w\_]+$/,
      :maxlength => 20

[:license, :timeout, :description, :url, :version, :author].each do |item|
  output item,
         :description => "Agent #{item}",
         :display_as => item.to_s.capitalize
end
