module Puppet::Parser::Functions
newfunction(:validate_re, :doc => <<-'ENDHEREDOC') do |args|
Perform simple validation of a string against a regular expression. The second
argument of the function should be a string regular expression (without the //'s)
or an array of regular expressions. If none of the regular expressions in the array
match the string passed in, then an exception will be raised.
Example:
These strings validate against the regular expressions
validate_re('one', '^one$')
validate_re('one', [ '^one', '^two' ])
These strings do NOT validate
validate_re('one', [ '^two', '^three' ])
