Installation

From github, download the module into your modulepath on your Puppetmaster. If you are not sure where your module path is try this command:

puppet --configprint modulepath

Depending on the version of Puppet, you may need to restart the puppetmasterd (or Apache) process before the functions will work.

Functions

kwalify

This function allows you to validate Puppet data structures using Kwalify schemas as documented here:

http://www.kuwata-lab.com/kwalify/ruby/users-guide.01.html

To validate, create a schema in Puppet:

$schema = {
  'type' => 'seq',
  'sequence' => [
    { 'type' => 'str' }
  ]
}

And create some content that you want validated:

$document = ['a', 'b', 'c']

And then use the function to validate:

kwalify($schema, $document)

The function will throw an error and list all validation errors if there is a problem otherwise it succeeds silently.
