puppet-lint explicit Hiera class parameter lookup check

Extends puppet-lint to ensure there are no explicit calls to hiera() in the class parameters.

In our code base we would rather have a class lookup values for its parameters using Puppets automatic data binding functionality rather than scatter a number of direct, unpredictably name spaced, hiera calls throughout our manifests. This puppet-lint plugin helps us with that goal by finding any explicit hiera calls in a classes parameter section.

class no_explicit_lookups (
  $my_content = hiera('my::nested::key', 'baz')
) {
  file { '/tmp/foo':
    content => $my_content,
  }
}

To use this plugin add the following line to your Gemfile

gem 'puppet-lint-explicit_hiera_class_param_lookup-check'

and then run bundle install.

This plugin provides a new check to puppet-lint.

explicit hiera() lookup of my::sample::key
