# Puppet Labs Standard Library #
This module provides a "standard library" of resources for developing Puppet
Modules. This modules will include the following additions to Puppet
* Stages
* Facts
* Functions
* Defined resource types
* Types
* Providers
This module is officially curated and provided by Puppet Labs. The modules
Puppet Labs writes and distributes will make heavy use of this standard
library.
# Compatibility #
This module is designed to work with Puppet version 2.6 and later. It may be
forked if Puppet 2.7 specific features are added. There are currently no plans
for a Puppet 0.25 standard library module.
# Functions #
Please see `puppet doc -r function` for documentation on each function. The
current list of functions is:
* getvar
* has\_key
* loadyaml
* merge.rb
* validate\_array
* validate\_bool
* validate\_hash
* validate\_re
* validate\_string
## validate\_hash ##
$somehash = { 'one' => 'two' }
validate\_hash($somehash)
## getvar() ##
This function aims to look up variables in user-defined namespaces within
puppet. Note, if the namespace is a class, it should already be evaluated
before the function is used.
$namespace = 'site::data'
include "${namespace}"
$myvar = getvar("${namespace}::myvar")
