module Puppet::Parser::Functions
newfunction(:pick, :type => :rvalue, :doc => <<-EOS
This function is similar to a coalesce function in SQL in that it will return
the first value in a list of values that is not undefined or an empty string
(two things in Puppet that will return a boolean false value). Typically,
this function is used to check for a value in the Puppet Dashboard/Enterprise
Console, and failover to a default value like the following:
$real_jenkins_version = pick($::jenkins_version, '1.449')
The value of $real_jenkins_version will first look for a top-scope variable
called 'jenkins_version' (note that parameters set in the Puppet Dashboard/
Enterprise Console are brought into Puppet as top-scope variables), and,
failing that, will use a default value of 1.449.
