module Puppet::Parser::Functions
newfunction(:validate_absolute_path, :doc => <<-'ENDHEREDOC') do |args|
Validate the string represents an absolute path in the filesystem. This function works
for windows and unix style paths.
The following values will pass:
$my_path = 'C:/Program Files (x86)/Puppet Labs/Puppet'
validate_absolute_path($my_path)
$my_path2 = '/var/lib/puppet'
validate_absolute_path($my_path2)
$my_path3 = ['C:/Program Files (x86)/Puppet Labs/Puppet','C:/Program Files/Puppet Labs/Puppet']
validate_absolute_path($my_path3)
$my_path4 = ['/var/lib/puppet','/usr/share/puppet']
validate_absolute_path($my_path4)
The following values will fail, causing compilation to abort:
validate_absolute_path(true)
validate_absolute_path('../var/lib/puppet')
validate_absolute_path('var/lib/puppet')
validate_absolute_path([ 'var/lib/puppet', '/var/foo' ])
validate_absolute_path([ '/var/lib/puppet', 'var/foo' ])
$undefined = undef
validate_absolute_path($undefined)
ENDHEREDOC
# The deprecation function was being called twice, as validate_absolute_path calls is_absolute_path. I have removed it from here so it only calls deprecation once within is_absolute_path.

require 'puppet/util'

raise Puppet::ParseError, ("validate_absolute_path(): wrong number of arguments (#{args.length}; must be > 0)")
end
args.each do |arg|
# put arg to candidate var to be able to replace it
candidates = arg
# if arg is just a string with a path to test, convert it to an array
# to avoid test code duplication
unless arg.is_a?(Array) then
